Answer:

28.6 m²

Step-by-step explanation:

The measurements of the square are 4 by 4; this gives us an area of

4(4) = 16 m²

The quarter circle has a radius of 4 m.  The area of a circle is given by

A = πr².

Since we have a quarter circle, we multiply this by 1/4:

A = 1/4πr²

Using 3.14 for π and 4 for r,

A = 1/4(3.14)(4²) = 1/4(3.14)(16) = 3.14(4) = 12.56 m²

Together this gives us a total area of 16+12.56 = 28.56 m².

This rounds to 28.6 m².

In a recent year, 31% of all college students were enrolled part-time. If 8.6 million college students were enrolled part-time t
Ronch [10]

Answer:

28 million college students.

Step-by-step explanation:

We can represent all college students as x. This means that all part-time college students are \frac{31}{100}x. Because all part-time college students are also equal to 8.6 million, we have 8,600,000=\frac{31}{100}x. To find the number of total college students, or x, we have to multiply by 100/31 to get rid of the fraction on the other side:

8,600,00\cdot\frac{100}{31}=x

The left side of the equation evaluates as 27,741,935.5. Because we are asked to round to the nearest million, we have to round to 28 million, which is the closest.

-f(3f-7)=0 solve equation<br>​
kenny6666 [7]

Answer:

F=0 or (7/3)

Step-by-step explanation:

When F is 0, the equation reads -0(3(0)-7)=0. The outside 0 will multiply by everything and make it equal 0. When F is 7/3, the inside of the parenthesis read 3(7/3)-7. This equals 7-7. It'll end up being (7/3)0, which equals 0.
