Answer:
About 4.2 ft
Explanation:
The area of the traingle can be calculated in two ways.
where width = 4.4 ft and length = 13.6 ft.
Putting in the values for width and length gives
The other way that the area can be calculated is
where height = vertical length and base = 14.3 ft; therefore.
This must equal the area of the triangle we found above; therefore,
dividing both sides by 7.15 gives
which is our answer!
This is the start to the approach that would be taken to get both variables in terms of only one so it can be solved but since the numbers are so small you could easily test out numbers and figure out that it's 6 and 10 feet.
length = width + 4
length * width = 60
(width + 4) * width = 60
Answer:
B
Step-by-step explanation:
The number 
is 8 times greater than 
thus, 
multiply both sides by 
we get 
if we take a = 2.5 and b = 3.1 we get 2.5/3.1 = 0.8
then B is the answer
Volume of cylinder = πr²h = π x 4² x 6 = 96π
volume of cone = 1/3πR²H = 1/3π x 8² x 12 = 256π
You can see that volume of cone is more than twice of volume of cylinder. So she is not correct
Answer:
-7
Step-by-step explanation:
-7
EXPLANATION
The only numbers that have a distance of 7 from zero on the real number line are -7 and 7.
-7 is to the left of zero while 7 is to the right of zero.
But this two numbers are all 7 units from zero.
In other words, the absolute values of this numbers is 7.
