Which of the following girls will have the greatest percent of change in height if they each grow 3 inches over the summer?Girl Current Height
Ann 60 inches
Betty 62 inches
Carol 64 inches
Diana 66 inches

Answers

If you would like to know which of the girls will have the greatest percent of change in height, you can calculate this using the following steps:

x% of 60 inches is 63 inches
x% * 60 = 63
x/100 * 60 = 63
x = 63 * 100 / 60 = 105% ... 5%

y% * 62 = 65
y/100 * 62 = 65
y = 65 * 100 / 62 = 104.84% ... 4.84%

w% * 64 = 67
w/100 * 64 = 67
w = 67 * 100 / 64 = 104.69% ... 4.69%

z% * 66 = 69
z/100 * 66 = 69
z = 69 * 100 / 66 = 104.55% ... 4.55%

The correct result would be Ann (60 inches).

Answer:

ann 60 inches

You and your friends pick up seven movies to watch over a holiday. You have time to watch only two. In how many ways can you select the two to watch?

Answers

Answer:

There are 21 ways to select the two movies to watch.

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

${n\choose k}=(n!)/(k!(n-k)!)$

It is provided that there are n = 7 movies to watch.

But we only have time for k = 2.

Compute the total number of ways in which we can select 2 movies from 7 as follows:

${7\choose 2}=(7!)/(2!(7-2)!)$

$=(7!)/(2!* 5!)\n\n=(7* 6* 5!)/(2!* 5!)\n\n=(7*6)/(2* 1)\n\n=21$

Thus, there are 21 ways to select the two movies to watch.

2+7x=4-3x I need help solving

Answers

X=1 for the first equation for the second X=9 Because 2+7=9*1=9 then you do 4-3=1*9. GOOD LUCK!(:

   2 + 7x = 4 - 3x
      + 3x + 3x
   2 + 10x = 4
- 2    - 2
   10x = 2
      10 10
   x = 0.2

Find the area of the shaded region. Round your answer to the nearest hundredth.

Answers

4 semicircles of 90º=1 circle

Area of the shade region=area of the square - area of a circle

1)we calculate the area of the square.
area of a square =slide²
slide=8 m

area of a square=(8 m)²=64 m².

2) we calculate the area of the circle:
area of a circle=πr²
r=4 m

area of a circle=π(4 m)²=16π m²≈50.27 m²

3) we calculate the area of the shaded region:

Area of the shaded region=64 m² - 50.27 m²=13.73 m²

answer:The area of the shaded regios is 13.73 m²

8 times 8 is 64 so rounded to the neArest hundreth it is 100
