Answer:

g(f(-1)) = 2

Step-by-step explanation:

f(x) = 2 + x

g(x) = 3 - x

if you need to find g(f(-1)); find f(-1) first

f(-1) = 2 + (-1) = 1

f(-1) =1; now plug this into g(1)

g(1) = 3 - 1 = 2

Answer:

55% percentage mark up

Step-by-step explanation:

Formula = Gross profit / Cost of item * 100 First we find the Cost of item = 39.99 / 06 = 66.65 as 66.65 * 0.60 = 39.99 then we find the Gross profit 66.65 - 29.99 = 36.66 then plug into the formula 36.66/66.65 * 100 =55.0037509% = 55%

Helen has 48 cubic inches of clay to make a solid square right pyramid with a base edge measuring 6 inches. Which is the slant h

Nikitich [7]

Answer: 5 inches

Step-by-step explanation:

Given: Volume of clay = 48 cubic inches

If we make a solid square right pyramid with a base edge a= 6 inches.

Then its base area = $a^2=6^2=36\ inches^2$

we know that volume of square right pyramid= $\frac{1}{3}\times\ a^2h$

Therefore, volume of square right pyramid made by all of clay= $\frac{1}{3}\times\ a^2h$ =48 cubic inches

$\Rightarrow\frac{1}{3}\times\ (36)\times\ h=48\\\Rightarrow12h=48\\\Rightarrow\ h=4\ inches.....\text{[Divide 12 on both sides]}$

Now, slant height $l=\sqrt{(\frac{a}{2})^2+h^2}$

$\\\Rightarrow\ l=\sqrt{3^2+4^2}\\\Rightarrow\ l=\sqrt{9+16}\\\rightarrow\ l=\sqrt{25}\\\Rightarrow\ l=5$

The slant height of the pyramid if Helen uses all the clay=5 inches

What is another way to write the equation 7/8x3/4=-6

prohojiy [21]

Another way to write the equation is 7x + 54 = 0

<h3>How to rewrite the equation</h3>

Given the equation;

$\frac{7}{8}x + \frac{3}{4} = -6$

Find the LCM on the left side, which is 8

$\frac{7x + 6}{8} = -6$

Cross multiply

$7x + 6 = -6$ × $8$

$7x + 6 = -48$

Collect like terms

$7x = -48 - 6$

$7x = -54$

Take all to one side

$7x + 54 = 0$

Thus, another way to write the equation is 7x + 54 = 0
