Answer:
a. C(0.99,280) = $8.66
This represents the cost of driving 280 miles if gas costs $0.99 per gallon.
b. C(1.02, 178)=5.67 would be the cost of traveling 178 miles when the price of gas is $1.02 per gallon
Answer:
4
Step-by-step explanation:
A simple matter of using Pythagoras. The hypotenuse is the ladder, and one of the legs is the wall, and we have to figure out the value of the other leg.
The Pythagorean formuda is (hypotenuse = a): a² + b² = c² (b and c are the other sides)
applying the values: a = 5 and b or c is 3 (I'll put b = 3)
5² = 3² + c²
25 = 9 + c²
25 - 9 = c²
16 = c²
√16 = c
4 = c
c = 4
Answer:
Where, x ≥ 0
Step-by-step explanation:
Given,
The rectangular picture has,
Length = 6 inches,
Width = 8 inches,
Suppose x be the width( in inch ) of the piece of wooden,
After joining the piece,
New length = 6 + 2x ,
New width = 8 + 2x
So, the area of the final figure,
According to the question,
V ≤ 100 inch²
But, width can not be negative,
i.e. x ≥ 0
Answer:
(I don't know if this is correct)
To find the length of the rectangle, you need to first do 20 x 2 = 40 because when you finding the perimeter you have to do W + L + W + L = P (or Wx2 + Lx2 = P). You then subtract 40 from 68 (68 - 40) where you get 28 left. you then just divide 28/2 and you get 14. I may be way off but that's how I learned it.
