Enrique predicts that he can make additional money from sales of accessories and services for computer
products sold by his store. The table at the right
shows predicted percent returns for such sales. For
example, if the store makes x dollars selling computer
products, Enrique predicts the store will make 0.05x
dollars from selling accessories.
Part A
In January and February of this year, the store made $2,500 from sales of
accessories and services. Let x represent the amount the store will make from
sales of computer products from March through December. Write an equation
that represents the predicted amount y that the store will make from sales
of accessories and services for the entire year. If Enrique predicts sales from
accessories and services for the entire year will be $5,000, about how much
money must be made from computer product sales from March through
December? Explain. PL HELP NOW

8y^50

step-by-step explanation:

addition

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
