Answer:

The percent of increase is 32.43%.

Step-by-step explanation:

Take the difference of his new score and the old score.

37-25 = 12

To find the percent change, take that difference and divide it by the new score. Then multiply that answer by 100%.

12/37 = .3243

.3243 x 100% = 32.43%

a beach ball has a diameter of 10 inches. What is the volume of air contained inside the beach ball? Use 3.14 for pi. Round your
erastova [34]

Answer:

A beach ball is a sphere, so we will need to know how to find the volume of a

sphere. V = 4Pi * (r ^ 3 / 3)

We have the diameter, but not the radius. To find the radius, it is half of the

diameter.

10÷2=5 Now let's plug it in.

4T(5³/3) Let's solve.

4pi = 12.56

5³= 125

125÷3= 41.67 (repeating 6) 41.67x12.56=523.3752

523.33 cubic inches is the volume of

air contained inside the beach ball. The reason I picked that answer is because a repeating 6. So we should expect for

we rounded up to 41.67, when there was

the answer to be a couple decimals lower

from the answer we got. Tell me if this helps!!

How many solutions does the system of equations below have?<br><br> y= 3x + 4<br> 2y -8 = 6x
Cerrena [4.2K]

Answer:

infinitely many solutions (infinite solutions)

Step-by-step explanation:

2y - 8 = 6x

   +8    +8

-------------------------------

2y = 6x + 8

\frac{2y}{2} = \frac{6x}{2} + \frac{8}{2}

-------------------------------

y = 3x + 4

Because 3x + 4 = 3x + 4, there are infinitely many solutions to this system of equations. This is because they're the exact same equations. Any substitution for x will give you a true statement to y when compared to the other equation.
