Answer:

a=11 yards

Step-by-step explanation:

The two triangles are similar as it states. The area is also similar as the sides are similar.

38.5/7 is 5.5

5.5*2 which is the corresponding similar side length, is 11 so a, the missing side length must be 11

Find g(a - 1) when g(x) = 5x - 4.

lesya692 [45]

Answer:

${ \tt{g(x) = 5x - 4}}$

• solve when x is a - 1:

${ \tt{g(a - 1) = 5(a - 1) - 4}} \\ \\ { \tt{g(a - 1) = 5a - 5 - 4}} \\ \\ { \boxed{ \tt{g(a - 1) = 5a - 9 \: }}}$

if y represents total earnings in dollars and x represents hours worked, then which equation models the wages of someone who mak

Klio2033 [76]

Answer: $y=11.50x$

Step-by-step explanation:

1. You have the following information given in the problem above:

- y represents total earnings in dollars .

- x represents hours worked.

2. Keeping on mind that the expression must model the wages of someone who makes $11.50 in an hour, this amount of money per hour must multiply the hours worked, which is represented by x.

3. Therefore, you can write the following equation:

$y=11.50x$

A solid oblique pyramid has a square base with edges measuring x cm. The height of the pyramid is (x + 2) cm. Which expression r

zavuch27 [327]

we know that

the volume of a solid oblique pyramid is equal to

$V=\frac{1}{3}*B*h$

where

B is the area of the base

h is the height of the pyramid

in this problem we have that

B is a square

$B=b^{2}$

where

$B=x^{2}\ cm^{2}$

$h=(x+2)\ cm$

substitute in the formula of volume

$V=\frac{1}{3}*x^{2}*(x+2)\\ \\V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}$

therefore

<u>the answer is</u>

$V=\frac{1}{3}*[x^{3} +2x^{2}]\ cm^{3}$

The formula for the area of a trapezoid with altitude k and bases m and n is . A=k/2 (m+n) solve for m..

SashulF [63]

Answer:

$m=A\times\frac{2}{k}-n$

Step-by-step explanation:

Given : The formula for the area of a trapezoid with altitude k and bases m and n is $A=\frac{k}{2}(m+n)$

We have solve for m .

Consider the given formula $A=\frac{k}{2}(m+n)$

Multiply both side by $\frac{2}{k}$ , we have,

$A\times\frac{2}{k}=m+n$

Now subtract n both side, we have,

$A\times\frac{2}{k}-n=m$

Thus, $m=A\times\frac{2}{k}-n$
