The equation would be:
3/4x=16 1/2
So you would divide both sides by 3/4
and get 44 bags for the leftover 16 1/2 lb. of cookies.
Hope this helps a lot!

Find the volume of the following. Please round your answer to the nearest tenth. Please do not put units. Hint: You need to use
Sophie [7]

Answer:

<em>V = 1,568</em>

Step-by-step explanation:

<u>The Volume of a Square Pyramid</u>

Given a square-based pyramid of base side a and height h, the volume can be calculated with the formula:

\displaystyle V=\frac{1}{3}a^2h

We are given a square pyramid with a base side a=14 ft but we're missing the height. It can be calculated by using the right triangle shown in the image attached below, whose hypotenuse is 25 ft and one leg is 7 ft

We use Pythagora's theorem:

25^2=h^2+7^2

Solving for h:

h^2=25^2-7^2=625-49=576

h=\sqrt{576}=24

The height is h=24 ft. Now the volume is calculated:

\displaystyle V=\frac{1}{3}*14^2*24

V = 1,568

Lines a and b are perpendicular. The equation of line a is y=1/3x+3. What is the equation of line b
kykrilka [37]
Perpendicular lines have slopes that are negative reciprocals to each other, that is, if one slope is a/b, the other is -b/a
in this case, the given slope is 1/3, so the other line's slope is -3/1, which is -3
from the graph we see that the y intercept of line b is -4, so the equation of line b is: y=-3x-4

What is the domain function on the graph
sattari [20]
ANSWER

All real numbers greater or equal to -3.


EXPLANATION

The domain of the given function are values of x that make the function defined.


We can see from the graph that, the domain are x-values greater than or equal to -3.



In other words, we can find a corresponding y-value for all x-values greater than or equal to -3.

The correct answer is option D.
