rectangle has area 80 square centimeters. the rectangle is dilated using A as a center and a scale factor of 1/2 what is the area of the image

Answers

Answer 1

9514 1404 393

Answer:

  20 square centimeters

Step-by-step explanation:

The area of the dilated figure is the original area multiplied by the square of the dilation factor. The center of dilation is irrelevant.

  dilated area = (1/2)² × original area

  dilated area = 1/4 × 80 cm²

  dilated area = 20 cm²

24 swimmers are swimming in the pool. 9 of them are female. What fraction of swimmers are male?

Answers

Answer:

15/24 or 5/8

Step-by-step explanation:

Well 9 are female

The rest of the 24 has to be male so

24-9=15

15/24 or 5/8

The fraction of male swimmers is 5/8.

Given,

24 swimmers are swimming in the pool.

9 of them are female.

We need to find what fraction of male swimmers.

How do we find fraction of items from the total items?

We write in two parts numerator and denominator.

= Numerator / Denominator

= Number of required items / Total number of items

Find the total number of swimmers.

= 24

Find the number of male swimmers.

= Total swimmers - Female swimmers

= 24 - 9

= 15

Find the fraction of male swimmers.

= Number of male swimmers / Total number of swimmers
= 15 / 24

Taking out the common factor

= 3 x 5 / 3 x 8

= 5/8

Thus the fraction of male swimmers is 5/8.

Rachel is treating her three friends to go see The Avengers: End Game. Each movie ticket costs x dollars. Rachel orders each of them (including herself) candy that cost $3.75 each and drinks that cost $4.25 each.

Answers

Answer:

4(x+8) OR 4x+32

Step-by-step explanation:

4x+(4*3.75)+(4*4.25)

There are four people, so there are four tickets, four drinks, and four pieces of candy, so everything must be multiplied by four. Next, you need to either factor or simplify the equation.

If you want to factor it, the answer would be 4(x+8)

If you want it simplified, it would be 4x+32

You have a jar of Marbles in front of you 2 are Cordovan, 9 are yellow, 3 are white and 7 are red. What is the probability, as a fraction of selecting a marble that is white or yellow, followed by a marble that is Cordovan?​

Answers

Answer:

2/35

Step-by-step explanation:

Assuming that this is without replacement,

The total amount of marbles is 2+9+3+7, or 21.

9 are yellow, 3 are white. this makes 12.

The probability of selecting a white or yellow marble is 12/21.

Now without replacement (comment if it is with replacement.), there are 20 marbles left, and 2 are Cordovan. This means there is a 2/20 chance then of picking a Cordovan marble.

After multiplying the fractions we get

(12/21) * (2/20) = 2/35.

There is a 2/35 chance of selecting a yellow or white, then a cordovan marble.

Using the following data set calculate the mean 9,14,14,9,20,6,8,19,17,13,9

Answers

12.545 is the answer

Answer:

12.54

Step-by-step explanation:

When finding the mean, first you add all the numbers in the data:

9+14+14+9+20+6+8+19+17+13+9=138

And then you divide it by the following numbers in the set. In this data set, since there are 11 numbers, you would divide 138 by 11.

138\11=12.5454545

So the answer would be 12.54 if your rounding to the nearest hundred. If your rounding it by a whole number, it would be 13.

[tex]V=\pi r^{2}[/tex]

[tex]751=\pi r^{2}(10.7)[/tex] now we multiply pi and 10.71- i left it in the hundreths

place when i get my final answer ill round it to the tenths)

[tex]751=33.62r^{2}[/tex],  we need the [tex]r^{2}[/tex] alone so we now dive with 33. 62 on both sides, elimenating the 33.62. Now 751/ 33.62= 16.98.

now we square root it

[tex]\sqrt{16.98}[/tex] = 4.12 which rounded is 4.1

Answer:

solution given.:

radius=[r] let

height[h]=10.7in

volume[V] of cylinder=751 in³

π=3.14

we have

volume[V] of cylinder=πr²h

751=πr² ×10.7

r²=[tex] \frac{751}{10.7×3.14} [/tex]

r=[tex] \sqrt{22.353} [/tex]=4.73inch

so radius is 4.73in
