The figure below is made of 2 rectangular prisms. What is the volume of this figure?

mixer [17]

Answer:

6536 cubic in

Step-by-step explanation:

1. Split both the prisms apart- In doing so, you can simplify the problem.

2. Put in the #'s for the formula which in this case is V=L*W*H, we will start with the formula for the front one, V=7*8*1 or V=7*8

3. answer for the front is 56 cubic in, now we solve for the other half.

4. V=9*1*90 or V=9*90 which is 6480 cubic in.

5. add 6480 and 56 and your answer is 6536 cubic in as your answer.

Hope this helped ;D

This is the graph of f(x). What is the value of f(3)

zubka84 [21]

Answer:

exponential function, cool

Step-by-step explanation:

looks like f(x) = e ^x

So f(3) would be e^(3)

you can work this out on your calculator.

press [2ndf] [e^x]] [3] = 20

Best thing is draw a line up from x-axis to the curve, where it hits the curve you will have your answer

QUESTION 1

The given equation is

$2.5(10 - x) + 10 = 72 - 1.5(5x + 12)$
Clear the decimal by multiplying through by 10 to get,

$25(10 - x) + 100 = 720 - 15(5x + 12)$

Expand the bracket using the distributive property to get;

$250 - 25x + 100 = 720 - 75x - 180$

Group similar terms to get,

$- 25x + 75x = 720 - 250 - 100 - 180$

$50x = 720 - 530$

$50x = 190$

Divide through by 50 to get,

$x = \frac{190}{50}$

$x = \frac{19}{5}$

QUESTION 2

We want to solve the inequality,

$16x \: > \: 12(2x - 6) - 24$

We expand the bracket using the distributive property to obtain,

$16x \: > \: 24x - 72 - 24$

Group similar terms to get,

$16x - 24x \: > \: - 72 - 24$

Simplify to get,

$- 8x \: > \: - 96$

We divide both sides of the inequality by -8 and reverse the sign to obtain,

$x \: < \: \frac{ - 96}{ - 8}$

$x \: < \: 12$

QUESTION 3

Step 1.

Given:4(-6x – 3)+24x= -72x + 132

Step 2.

Distributive property:
-24x – 12 + 24x = -72x + 132

Step 3.

Combine like terms:
–12 = -72x + 132

Step 4.

Addition property of equality:

-144 = -72x

Step 5.

Division property of equality:

2=x

All the properties stated are correct.

Margot could pickle 500 cucumbers in 2 hours. She got tired and reduced her rate by one half. How long would it take her to pick

Mariulka [41]

Margot could pickle 500 cucumbers in 2 hours.
She got tired and reduced her rate by one half.
=> 250 cucumber in 2 hours
Let's solve how long would it take her to pickle 2000 cucumbers at thenew rate.
=> 2000 / 250 = 8 times 2 hours
=> it will take her 16 hours to do so.

What is the equation, in point-slope form, for a line that goes through (8, −4) and has a slope of −56 ?

olga55 [171]

The point-slope form:

$y-y_1=m(x-x_1)$

We have the point (8, -4) and the slope m = -56. Substitute:

$y-(-4)=-56(x-8)\\\\\boxed{y+4=-56(x-8)}$
