Answer:

Step-by-step explanation: Let variable x represent the 15¢ stamps, and variable y represent 20¢ stamps.

x= 3y-8

0.15x+0.20y = 4

Replace x in the second equation by (3y-8)

0.15(3y-8) + 0.20y = 4

0.45y - 1.2 +0.20y = 4

Collect like terms;

0.45y+0.20y = 4+1.2

0.65y = 5.2

Divide both sides by 0.65 to solve for y;

y= 5.2/0.65

y = 8

Replace in equation " x=3y-8 " to solve for x;

x = (3*8) -8

x=24 - 8

x = 16

Therefore, the 15¢ stamps are 16 in number, and the 20¢ stamps are 8 in number.

The total area to be painted is 8,316 square inches.

The bench has a rectangular base with dimensions 63 in by 14 in. The height of the bench is 54 in. The two faces that rest on the ground do not need to be coated with paint, so the total area to be coated is the sum of the areas of the four remaining faces.

The area of one of the longer faces is:

63 in × 54 in = 3,402 in²

The area of the other longer face is the same, so the total area of the longer faces is:

2 × 3,402 in² = 6,804 in²

The area of one of the shorter faces is:

14 in × 54 in = 756 in²

The area of the other shorter face is the same, so the total area of the shorter faces is:

2 × 756 in² = 1,512 in²

The total area to be coated with paint is the sum of the areas of the four remaining faces:

6,804 in² + 1,512 in² = 8,316 in²

Therefore, the total area to be coated with paint is 8,316 square inches.

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Step-by-step explanation:

When we're solving with scale factors, we either divide or multiply.

If the shape becomes larger, we multiply to get the new length.

If the shape becomes smaller, we divide to get the new length.

We're given:

Because the shape becomes larger, we have to multiply the original side length by the scale factor, 6, to get the new side length.

2.5 x 6 = 15

Answer:

(x, y) = (4, 11).

Step-by-step explanation:

We have two equations:

3(y-2x) = 9

x - 4 = 0

From equation 2, we have x = 4. We can substitute this value into equation 1 and solve for y:

3(y-2x) = 9

3(y-2(4)) = 9 (substitute x = 4)

3(y-8) = 9

3y - 24 = 9

3y = 33

y = 11

Therefore, the solution to the system of equations is (x, y) = (4, 11).

Answer:

Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.

Step-by-step explanation:

The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.

For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.

I've enclosed an attachment for that.

Answer:

probably my last question for the day but the answer is 28.26 square centimeters.

Step-by-step explanation:

The formula to find the area of a quarter circle is:

A = (1/4)πr^2

where A is the area and r is the radius.

Substituting the given values:

A = (1/4) × 3.14 × 6^2

A = 28.26

Rounding to the nearest hundredth, the approximate area of the figure is 28.26 square centimeters.

Answer:

On Monday, Marco practiced the piano for 7/10 hour. On Tuesday he practiced for 11/6 hour. To find out how many hours he practiced in total for these two days, we need to add these two amounts together.

We can add these two amounts together by converting them to a common denominator, in this case 24:

7/10 hour = (7/10) * (24/6) = 724/60 = 72/5 = 14/5 hour

11/6 hour = (11/6) * (24/6) = 114/6 = 112/3 = 22/3 hour

So the total number of hours he practiced for these two days is (14/5) + (22/3) = (14+44)/(5*3) = 58/15 hour

He is supposed to practice 5/4 hours each day. To find out how many hours he is still supposed to practice, we have to subtract the total number of hours he practiced from the total number of hours he is supposed to practice per day:

5/4 hour - 58/15 hour = (53)/(43) - (58/15) = 15/12 - 58/15 = (180-58) / (12*15) = 122/180 hour or 0.67 hour

So Marco is supposed to practice 0.67 hour more to meet his daily practice goal.
