Kwesi is putting on sunscreen. He uses 3 ml to cover 45 cm2 of his skin. He wants to know how many milliliters of sunscreen (9) he needs to cover 240 cm? of his skin. He assumes the relationship between milliliters of
sunscreen and area is proportional.
How many milliliters of sunscreen does Kwesi need to cover 240 cm? of his skin?

x = 12

y = 15

step-by-step explanation:

one that is bigger than 3 1/2

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
