The question is incomplete, below is the complete question:

The volume of a flask has been determined to be 26.918 mL, and the mass of the flask has been determined to be 32.634g. The student then emptied the flask and dried it once again. To the empty flask, he added pieces of metal until the flask was about half full. He weighed the stoppered flask containing the metal and found that its mass was 100.356g. Next, he filled the flask containing the metal with water, stoppered it, reweighed it and obtained a total mass of 121.860g.

a.) Find the mass of the metal in the flask. (show work)

b.) Find the mass of water in the flask. (show work)

c.) Find the volume of water in the flask. (show work)

d.) Find the volume of metal in the flask (show work)

e.) Find the density of the metal. (show work)

Answers:

a.  mass of metal in the flask = 67.722g

b. mass of water in the flask = 21.504g

c. volume of water in the flask = 21.562mL

d.) volume of metal in the flask = 5.356mL

e.) density of the metal = 12.644g/mL

Step-by-step explanation:

a.) mass of metal in the flask = (mass of flask + metal) - mass of empty flask

= 100.356 - 32.634 = 67.722g

b.) mass of water in the flask = (mass of flask when filled with metal and water) - (mass of flask when filled with metal alone)

= 121.860 - 100.356 = 21.504g

c. volume of the water in the flask :

in order to calculate the volume of water in the flask, the density formula is used as follows:

density = mass ÷ volume

volume = mass ÷ density.

where:

Density of water = 0.9973 g/mL

Mass of water as calculated above = 21.504g

∴ volume of water = 21.504 ÷ 0.9973 = 21.562mL

d.) volume of the metal in the flask:

Next, to calculate the volume of the metal in the flask:

volume of flask = volume of metal + volume of water

∴ volume of metal = volume of flask - volume of water

where:

volume of flask = 26.918mL (given)

volume of water = 21.562mL (calculated above)

∴ volume of metal = 26.918 - 21.562 = 5.356mL

e.) density of the metal:

Density = mass ÷ volume

where:

mass of metal = 67.722g ; volume of metal = 5.356mL

∴ Density of metal = 67.722 ÷ 5.356 = 12.644g/mL

When locating points or other mathematical objects precisely on a region, such as Euclidean space, a coordinate system is a technique that uses one or more numbers or coordinates. Locating a point or item on a the double plane requires the use of coordinates, which are pairs of integers. Two numbers called the x and y vectors are used to define a point's location on a 2D plane. a collection of numbers that indicate specific locations.

Here,

The slope method can be used to calculate the patient's heart rhythm after 42 minutes that use the secant line connecting the points with the specified values of t:

Heartbeat change / time change is the trend.

The heart rate can then be estimated using this slope value along with the number for heartbeats at t = 42 minutes.

A)Using coordinates 36, 2510, and 42, 2915 as examples:

Cardiac rate at 42 minutes = 2510 + (42 - 36) * 75 = 3140 Slope = (2915 - 2510) / (42 - 36) = 75

b) Using coordinates (38, 2647) and (42, 2915), respectively:

Cardiac rate at 42 minutes = 2647 + (42 - 38) * 67 = 2915 Slope = (2915 - 2647) / (42 - 38) = 67

c) Applying the values (40, 2784) and (42, 2915):

Heart rate at 42 minutes = 2784 + (42 - 40) * 65.5 = 2915.5 Slope = (2915 - 2784) / (42 - 40) = 65.5

Using coordinates (42, 2915), and (44, 3048), respectively:

Cardiac rate at 42 minutes = 2915 + (42 - 42) * 66.5 = 2915 Slope: (3048 - 2915) / (44 - 42) = 66.5

Answer:

No value

Step-by-step explanation:

No number exists because x is always x and 0 is never -5.

Answer:

  any value

Step-by-step explanation:

You want to know a value of x that makes x=x-5 a false statement.

The value x is never equal to a value 5 less than itself. The given equation is false no matter what the value of x is.

 x = x -5 is false for all values of x

Answer:

if those lines are parallel, then the m∠ = 92°

Step-by-step explanation:

The angle rule of corresponding angles or the corresponding angles postulate states that the corresponding angles are equal if a transversal cuts two parallel lines. Corresponding angles are equal if the transversal line crosses at least two parallel lines.

Since y is not equal to 10, hence the coordinate point does not fall on the line graph.

Since we are not given a graph, we will use the attached graph as a reference:

The equation of a line is expressed as y = mx + b

m is the slope

b is the y-intercept

Get the slope of the line

\(m = \frac{0-(-2)}{-2-0}\\m=\frac{2}{-2}\\m = 1\)

Since the line suts the y-axis at y = -2, hence b = -2

Get the equation of the line:

Recall that y = mx + b

y = x + (-2)

y = x - 2

Next is to check if the coordinate (5, 10) lies on the line

If x = 5

y = x - 2

y = 5 - 2

y = 3

Since y is not equal to 10, hence the coordinate point does not fall on the line graph.

Answer:

yehh it would be efffective

The tip of the minute hand on a clock travels a distance of 4π inches in 15 minutes.

The distance traveled by the tip of a minute hand on a clock can be calculated using the circumference formula.

The circumference of a circle is given by the formula:

C = 2πr C is the circumference, π is pi (approximately 3.14159) and r is the radius.

The distance from the center of the clock to the tip of the minute hand is the radius is 8 centimeters.

The circumference of the circle traced by the tip of the minute hand is:

\(\text{C} = 2\pi \text{r}\)

\(= 2\pi (8)\)

\(= 16\pi \ \text{centimeters}\)

Since the minute hand travels the full circumference of the circle in 60 minutes, in 15 minutes it will cover 15/60 = 1/4 of the circumference.

The distance traveled by the tip of the minute hand in 15 minutes is:

\(\text{Distance} = \huge \text(\dfrac{1}{4}\huge \text) \times C\)

\(= \huge \text(\dfrac{1}{4}\huge \text) \times (16\pi)\)

\(= 4\pi \ \text{centimeters}\)

Answer:

4π cm ≈ 12.6 cm

Step-by-step explanation:

The clock can be modelled as a circle, where the radius (r) is equal to the length of the minute hand:  r = 8 cm.

A clock face is divided into 12 equal sectors (numbered 1 to 12).

It takes 60 minutes for the minute hand to complete one revolution of the clock. Therefore, each sector represents the passing of 5 minutes.

This means that 15 minutes equals 3 sectors, which is a quarter of the circle.

To find the distance the tip of the minute hand travels in 15 minutes, we need to find a quarter of the circumference of a circle with radius 8 cm.

The formula for the circumference of the circle is C = 2πr, where r is the radius. Therefore, the equation to find the distance the tip of the minute hand travelled in 15 minutes is:

\(\sf Distance=\dfrac{2 \cdot \pi \cdot 8}{4}\)

Simplifying, we get:

\(\sf Distance=\dfrac{16 \cdot \pi}{4}\)

\(\sf Distance=4 \pi\)

Therefore, the minute hand will travel 4π cm or approximately 12.6 cm (to the nearest tenth) in 15 minutes.

Answer:

To convert euros to pounds, we have to multiply the amount in euros by the exchange rate. So, the sunglasses cost 90 * 0.875 = 78.75 pounds.

To use a suitable approximation, we can round the exchange rate to the nearest hundredth, which is 0.88. This makes the calculation easier and gives a close estimate of the actual value.

Using the rounded exchange rate, the sunglasses cost 90 * 0.88 = 79.2 pounds.

We can see that both the exact and the approximate values are greater than 70 pounds, so Elyas is wrong. The sunglasses cost more than 70 pounds

Step-by-step explanation:

Given that a line passes through two points

A(-2, -4) and B(4, 2)

Another point P(0, 4)

To find:

Which points lie on the line that passes through P and is parallel to line AB ?

Solution:

First of all, let us the find the equation of the line which is parallel to AB and passes through point P.

Parallel lines have the same slope.

Slope of a line is given as:

\(m=\dfrac{y_2-y_1}{x_2-x_1}\)

\(m=\dfrac{2-(-4)}{4-(-2)} = 1\)

Now, using slope intercept form (\(y = mx+c\)) of a line, we can write the equation of line parallel to AB:

\(y =(1)x+c \Rightarrow y = x+c\)

Now, putting the point P(0,4) to find c:

\(4 = 0 +c \Rightarrow c = 4\)

So, the equation is \(\bold{y=x+4}\)

So, the coordinates given in the options which have value of y coordinate equal to 4 greater than x coordinate will be true.

So, the correct options are:

The equation that can be used to determine the number of cans, c, the sophomores collected is c = 428 - x and c = 295.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Let x be the cans collected by Freshmen

Now it is given that,

Sophomores collected, c = 62 + x

Total cans collected = 428

⇒ Cans collected by Freshmen + Sophomores collected = 428

⇒ Sophomores collected = 428 -  Cans collected by Freshmen

⇒ Sophomores collected = 428 - x

⇒  c = 428 - x

this is the equation used to determine the number of cans, c, the sophomores collected.

∴ 62 + x = 428 - x

Taking alike terms together we get,

x + x = 428 - 62

⇒ 2x = 366

or, x = 133

Thus, Sophomores collected, c = 428 - 133

⇒  Sophomores collected, c = 295.

Thus,The equation that can be used to determine the number of cans, c, the sophomores collected is c = 428 - x and c = 295.

A personal example of a measurement I use routinely is converting weight from U.S. customary units to metric units. Let's convert pounds to kilograms.

To convert pounds to kilograms, we use the conversion factor of 1 pound = 0.453592 kilograms.

For example, if I have a weight of 150 pounds, I can calculate the equivalent weight in kilograms as follows:

150 pounds * 0.453592 kilograms/pound = 68.0388 kilograms

Therefore, 150 pounds is approximately equal to 68.0388 kilograms.

In this conversion, we multiply the weight in pounds by the conversion factor to obtain the weight in kilograms. By using the appropriate conversion factor, we can accurately convert weights from U.S. customary units to metric units.

It's important to note that conversion factors may vary slightly depending on the rounding used and the exact value of the conversion factor.

a) Probability will be \(nb(x; 2, 0.4) = (x + 1 choose 2) * (0.4)^2 * (0.6)^(x)\)

b)Probability is b(2; 4, 0.4) = \((4 choose 2) * (0.4)^2 * (0.6)^2\) = 0.2304 (rounded to four decimal places)

c)b(2; 2, 0.4) =\((2 choose 2) * (0.4)^2 * (0.6)^0\) = 0.16

d)E(X) = r*(1-p)/p = 2*0.6/0.4 = 3 boxes

(a) The probability that x boxes do not have the desired prize can be modeled by a negative binomial distribution with parameters r=2 (since we want to obtain 2 prizes), p=0.4 (since the probability of obtaining the prize in any given box is 0.4), and x being the number of boxes purchased before obtaining the second prize. Therefore, the probability is given by:

\(nb(x; 2, 0.4) = (x + 1 choose 2) * (0.4)^2 * (0.6)^(x)\)

(b) The probability of purchasing four boxes and obtaining two prizes can be modeled by a binomial distribution with parameters n=4 (since four boxes are purchased), k=2 (since we want to obtain two prizes), and p=0.4 (since the probability of obtaining the prize in any given box is 0.4). Therefore, the probability is given by:

b(2; 4, 0.4) = \((4 choose 2) * (0.4)^2 * (0.6)^2\) = 0.2304 (rounded to four decimal places)

(c) The probability of purchasing at most four boxes and obtaining two prizes can be found by summing the probabilities of purchasing 2, 3, or 4 boxes and obtaining two prizes. Using the binomial distribution with parameters n=2 and p=0.4 for the case of purchasing 2 boxes and obtaining two prizes, we have:

b(2; 2, 0.4) =\((2 choose 2) * (0.4)^2 * (0.6)^0\) = 0.16

Using the negative binomial distribution with parameters r=2 and p=0.4 for the case of purchasing 3 boxes and obtaining two prizes, we have:

nb(1; 2, 0.4) = (1 + 2 choose 2) * (0.4)^2 * (0.6)^1 = 0.288

Using the negative binomial distribution with parameters r=2 and p=0.4 for the case of purchasing 4 boxes and obtaining two prizes, we have:

nb(2; 2, 0.4) = (2 + 2 choose 2) * (0.4)^2 * (0.6)^2 = 0.3456

Therefore, the probability of obtaining two prizes in at most four boxes is:

0.16 + 0.288 + 0.3456 = 0.7936 (rounded to four decimal places)

(d) The expected number of boxes without the desired prize can be found by multiplying the number of boxes needed to obtain the prize (on average) by the probability of not obtaining the prize, which is given by:

E(X) = (1 - p)/p = 0.6/0.4 = 1.5 boxes

The expected number of boxes needed to obtain two prizes can be found using the negative binomial distribution with parameters r=2 and p=0.4, which gives:

E(X) = r*(1-p)/p = 2*0.6/0.4 = 3 boxes

The property you are referring to is called the associative property of multiplication. According to this property, when multiplying three numbers, the grouping of the numbers does not affect the result. In other words, you can change the grouping of the factors without changing the product.

In the equation you provided: 3x(5x7) = (3x5)7

The associative property allows us to group the factors in different ways without changing the result. So, whether we multiply 5 and 7 first, or multiply 3 and 5 first, the final product will be the same.

Step-by-step explanation:

In order to find the value of x, which coincides with one of the diagonals of the rhombus, use the following formula for the area of a rhombus:

A = (d1 · d2)/2

where d1 and d2 are the two diagonals of the figure.

In this case, you have:

A = 45

d1 = BD = 6

d2 = AC = x

replace the previous values of the parameters into the formula for A, and solve for x, as follow:

45 = (6·x)/2

45 = 3x divide by 3 both sides

45/3 = x

15 = x
