40x18=720 for the whole thing
720-320= 400 for the deck
Answer:
B. 
Step-by-step explanation:
The given quadratic trinomial is;

Comparing this to
, we have a=5,b=17,c=6.

Two factors of 30 that add up to 17 is 15 and 2.
We split the middle term to obtain;

We factor by grouping;

Factor further

The correct answer is B.
Answer: 70 - 40 = 30
Step-by-step explanation:
Answer:
g = - 5
Step-by-step explanation:
2 - 8g = -3 - 9g
Add 9g to both sides of the equation:
2 - 8g + 9g = -3 - 9g + 9g
2 + 1g = - 3
Subtract 2 from both sides of the equation:
2 - 1g - 2 = - 3 - 2
1g = -5
Divide both sides of the equation by 1:

g = -5
The complete question in the attached figure
Part A) How much sand is currently in the container?
[sand currently in the container]=(5)*(4 1/2)*(2.25)-----> (5)*(4.5)*(2.25)
[sand currently in the container]=50.625 in³
the answer Part a) is 50.625 in³Part B) How much more sand could the container hold before?
[sand could the container hold before]=[5*4.5*3]-[50.625]
[sand could the container hold before]=[67.5]-[50.625]------> 16.875 in³
the answer Part B) is 16.875 in³
Part C) What percent of the container is filled with sand?
the volume of container is [5*4.5*3]=67.5 in³
the volume filled with sand=50.625 in³
therefore
if 100%----------------> 67.5 in³
X---------------------> 50.625 in³
X=(50.625*100)/67.5=75 %
the answer Part C) is 75%
