6t - 20 - 32u
When t = 6, u = 1/4
6(6) - 20 - 32(1/4)
36 - 20 - 8
16 - 8

Which fraction is equivalent to 2/5? A. 4/10 B. 2/10 C. 1/2 D. 4/6

Lelechka [254]

Hey there James!

So, just remember, 2/5 is almost half of 1.

When it is almost half of 1, this means that it would have to be 2.5/5

This would mean that 4/10 would be your answer, because it is almost half of 1 also.

Hope this helps.

A figure is composed of a semicircle and a right triangle. Determine the area of the shaded region. Use 3.14 for π and round to

Aliun [14]

Answer:

$A=9.5\ ft^2$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of triangle plus the area of semicircle

$A=\frac{1}{2}bh+\frac{1}{2}\pi r^{2}$

we have

$b=4\ ft$

Find the height of the right triangle applying the Pythagorean Theorem

$5^2=h^2+4^2$

$h^2=9\\h=3\ ft$

The radius of the semicircle is half the height of triangle

$r=3/2=1.5\ ft$

substitute in the formula

$A=\frac{1}{2}(4)(3)+\frac{1}{2}(3.14)(1.5)^{2}$

$A=6+3.5=9.5\ ft^2$

9(2w−y)=21w−9y Solve for y

valentinak56 [21]

9(2w−y)=21w−9y

First you multiply the numbers in the parenthesis by 9

$18w-9y=21w-9y$

subtract. 21w-18w=3w

$-9y=3w-9y$

add. -9y+9y=0

$0=3w$

divide.

$0=w$

Final answer is 0.
