Luke is building a storage building and needs to have a slab of concrete poured. He knows the contractor charges an initial cost
of $95 plus an additional $3.50 per square foot of concrete. Which function can be used to determine the cost, in dollars, to pour a concrete slab with an area of x square feet? A) f(x) = 3.5x + 95 B) f(x) = 9.5x + 3.5 C) f(x) = 95x + 3.5 D) f(x) = 98.5x
y is the total cost, than you would need to multiply x, the number additional number of square feet, which is 3.5x. you would then add 95 dollars to the equation to represent the initial fee. So the equation would look like Y=3.5x+95.
2*2-1/3 yards= 4-2/ yards =14 feet. THE SHADOW IS HALF THE HEIGHT OF OBJECT, SINCE A 6 FEET BOY CASTS A 3 FEET . SO THE POLE WILL BE TWICE THE LENGTH OF ITS SHADOW. try this
