Answer:
Hypotenuse² = Base² + Altitude²
35² = 15² + x²
1225 = 225 + x²
x² = 1225 - 225
x² = 1000
<u>X = 10√10</u>
Answer: y = -3
Explanation:
-8 = 2y - 2
-2y = -2 + 8
y = 6/-2
y = -3
Answer:
3. 16
Explanation:
Factor the numerator and denominator and cancel the common factors.
5 x 5/2 = 25/2
answer
25/2 units
First we need to calculate the volume which is Base*depth or length*width*depth
first we have to change all the units so they are the same, 3 inches in this case will equal 1/4feet
multiply all the numbers together
35ft*12ft*1/4foot= 105 cubic feet
however the problem says the cost per cubic *yards*
so take the 105 cubic feet and divide by 3 (3 feet to a yard)
105/3 = 35 cubic yards
the cost of 35 cubic yards of concrete =
35*125= $4375
