grand coulee dam (g) contains 2.5 times as much concrete as the hover dam (h)
Therefore,
g = 2.5 * h
h = 3.5 million
g = 2.5 * 3.5
g = 8.75 million yards of concrete
Answer:
$ 1349.746624
Step-by-step explanation:
The volume of a cylinder
The formula for calculating the volume of a cylinder is expressed as:
V=πr²h
where:
r is the radius
h is the height
Given the following parameters
r = d/2 = 1.5/2 = 0.75ft
h = 30ft
Get the volume of the cylinder
V=π(0.75)²(30)
V= 53.0144...ft³
If the wod costs $25.46 per cubic foot, hence the cost of the wood will be 53.0144*25.46 = $ 1349.746624
Answer:
$133.77
I am pretty sure that this is the answer.
Step-by-step explanation:
1 + (1.25)^29 = 646.23
200 + (20 x 29) = 780
780 - 646.23 = 133.77
Tell me if I am wrong.
If right, please give me brainliest.
The polynomial is 3x^2 + 10x + 3 and the two factors are (3x+1) and (x+3), because
(3x+1)(x+3) = 3x^2 +9x + x +3 = 3x^2 + 10x +3
7^50
= 1.798 × 10^42
