Answer:

Step-by-step explanation:

\(2-\frac{3}{4}x =\frac{2}{5}\\8-3x=\frac{8}{5}\\40-15x=8\)

I simply multiplied the equation on both sides by the denominators of each fraction to get whole numbers. You can also do this by multiplying by 20, since the product of the denominators is 20 and will guarantee to create a numerator that creates a fraction that is also a whole number.

20(3/4)=60/4=15

20(2/5)=40/5=8

20(2)=40

Answer:

the tens place

Step-by-step explanation:

The tens place value would help you write 50/1,000 as 5/100 because to get 50 to 5, you would need to get rid of the tens place. In other words, you would need to divide by 10.

50 divided by 10 is 5

1,000 divided by 10 is 100

Answer: a

Step-by-step explanation:

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Part A: To calculate the measures of center, we can find the median and the mean for each school.

For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.

To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.

For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.

To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):

18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.

Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.

The measures of center for Seaside School are: median = 15, mean ≈ 15.9.

Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.

For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.

To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.

For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.

To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.

Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.

The measures of variability for Seaside School are: range = 15, IQR = 6.

Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

Answer:

50.23 and 50.24 are both rational numbers.

Step-by-step explanation:

Rational numbers can be written like a ratio.

●Whole numbers (2, 15, 77) are rational bc just put a 1 underneath it (2/1, 15/1, 77/1) now its a ratio.

●Fractions are rational bc the fraction is exactly the ratio (1/2, 5/8, 65/111)

●Decimals that "terminate" that is end or stop are rational like your problem (50.23, 50.24) and ALSO decimals that repeat (2.33333..., 7.666666...) We can do some math on these and find the ratio that is equal to the decimal.

50.23

= 50 + 23/100

= 50•(100/100) + 23/100

= 5000/100 + 23/100

= 5023/100

50.23 is equal to 5023/100.

50.24 = 5024/100 = 2512/50 = 1256/25

Briefly, decimals that do not end either with no pattern or even with a pattern, but not repeating...they are Irrational. (pi, e, and any weird 4.531874569131187732678...no pattern, and 3.1121231234pattern but not a repeat)

Square roots of not-a-perfect square are Irrational (sqrt3, sqrt7, sqrt24) probably tmi, but hope this helps!

how it works with life

Answer & Step-by-step explanation:

The following sentence correctly uses parallel structure: "The scientific method consists of proposing your hypothesis, conducting your experiment, analyzing your data, and reporting your findings." In this sentence, all of the phrases are in the same form and describe actions that are part of the scientific method. Each phrase begins with a verb (proposing, conducting, analyzing, and reporting) and is followed by a noun that describes the action (hypothesis, experiment, data, and findings). This structure is parallel because each phrase has the same grammatical structure and describes a similar action.

The other sentences do not use parallel structure because they do not have the same grammatical structure or they do not describe similar actions. For example, in the first sentence, the phrases "propose a hypothesis" and "end with a reporting" are not parallel because they do not have the same grammatical structure. In the second sentence, the phrases "proposing your hypothesis" and "reporting your findings" are not parallel because they do not describe the same type of action (proposing is a mental process, while reporting is a physical action). In the third sentence, the phrases "begins with a hypothesis" and "reporting findings" are not parallel because they do not have the same grammatical structure (one begins with a verb and the other ends with a verb). Finally, in the fourth sentence, the phrases "hypothesize" and "reporting" are not parallel because they do not have the same grammatical structure (one is a verb and the other is a gerund).

Answer:

The scientific method begins with a hypothesis, continues with an experiment, then analyzing data, and reporting findings

Answer:

The images are;

A’ (5,2) B’ (2,1) and C’ (1,3)

Step-by-step explanation:

Firstly, we want to reflect across the x-axis

When we reflect a point (x,y) over x-axis, we get (x,-y)

So;

A ( 2,5) becomes (2,-5)

B (1,2) becomes (1,-2)

C ( 3,1) becomes (3,-1)

Then we proceed to rotate 90 degrees counterclockwise about the origin

Here we have;

(x,y) becomes (-y,x)

(2,-5) becomes (5,2)

(1,-2) becomes (2,1)

(3,-1) becomes (1,3)

Answer:

10?

Step-by-step explanation:

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

So our answer in pi form is 30.25π

Step-by-step explanation:

The circumference of a circle is given by the formulas :

\(2\pi r\) or \(\pi d\)  where r is radius and d is the diameter

Since

11π = 2πr

We can solve for r to use it in the area of a circle formula:

\(\frac{11\pi }{2\pi } = r\)

r = 5.5

The area of a circle is given by the formula:

\(\pi r^{2}\) where r is the radius/.

Since we found r we can find the area:

π(5.5)² = 30.25π

So our answer in pi form is 30.25π

Answer:

As you have not specified the format in which to give the answer, I am giving three ways of writing it:

\(\sf 30.25 \pi \ units^2\)

\(\sf \dfrac{121}{4} \pi \ units^2\)

95.03 units² (nearest hundredth)

Step-by-step explanation:

Formulae

(where r is the radius)

Given:

Therefore, use the given value and the circumference equation to find the radius:

⇒ circumference = 11π

⇒ 2πr = 11π

⇒ 2r = 11

⇒ r = 5.5

Now we have found the radius, simply substitute this into the equation for area of circle:

⇒ area of a circle = πr²

                             = π5.5²

                             = 30.25π units²

Answer:

the two dimensions are represented by rows and columns.

Step-by-step explanation:

The surface area of the top open cylinder is 6810.149 sq.cm.

A cylinder is a three-dimensional solid that consists of two congruent surfaces (bases) and one lateral surface.

Surface area of a cylinder = Base area + Lateral area

Base area of a cylinder = 2 × π × r²

Lateral area of a cylinder = (2 × π × r) × h

Therefore, here base area of a cylinder = 2× π × 12²

                                                                  = 5837.27 sq.cm.

And, lateral area of a cylinder = (2 × π × 12) × 2

                                                  = 972.8784 sq.cm.

Therefore, total surface area of a cylinder = 5837.27 + 972.8784

                                                                      = 6810.149 sq.cm.
