Answer:
the number of boxes that would take fill
the storage completely is 6<u>0 boxes.</u>
Step-by-step explanation:
given:
A storage unit has the dimensions 6 ft. x 7 1/2 ft. x 4 1/2 ft.
find:
What number of
1 1/2 ft. x 1 1/2 ft. x 1 1/2 ft. cardboard boxes would it take to completely
fill this storage unit?
Volume of a storage unit = 6 x 7.5 x 4.5
Volume of a storage unit = 202.5 ft³
Volume of a cardboard box = 1.5 x 1.5 x 1.5
Volume of a cardboard box = 3.38 ft³
to get the number of cardboard boxes to fill in the storage unit,
Number of boxes = <u> 202.5 ft³ </u>
3.38 ft³
Number of boxes = 60
therefore,
the number of boxes that would take fill the storage completely is 60 boxes.
Answer:
B seems right
Step-by-step explanation:
Answer:
f(x) = 1/25x² - 1
Step-by-step explanation:
Given that:
The quadratic function f(x) = y = ax² + bx + c
Replace (x,y) = (5,0)
0 = a5² + b5 + c
0 = 25a + 5b + c ---- (1)
The differential eqaution;dt/dx = 2ax + b at (x,y) = (0, -1) it has minimum.
Thus, dy/dx = 0
2ax + b = 0
2a(0) + b = 0
0 + b = 0
b = 0 --- (2)
Now, replace (x,y) = (0, - 1) into equation (1)
Then;
-1 = 0 + 0 + c
c = -1
From equation (1)
0 = 25a + 5(b) + c
0 = 25a + 5(0) + c
c = - 25a
a = - c/25
a = -(-1)/25
a = 1/25
Therefore; the derived quadratic equation:
y = ax² + bx + c
y = 1/25x² + (0)(x) - 1
y = 1/25x² - 1
f(x) = 1/25x² - 1
Answer:
18x + 91
Step-by-step explanation:
Well, we know the number must be above 350,000 because it was rounded up to 400,000. In order for the number to round down to 350,000 the number would have to be between 350,000-354999. So, the number could be any number in between those two numbers.
For example: The number COULD be 351,000 but, that is not the only possible answer<span>.
make sense?
