Kwesi is putting on sunscreen. he uses 3\text{ ml}3 ml to cover 45 \text{ cm}^245 cm 2 of his skin. he wants to know how many milliliters of sunscreen (g)(g) he needs to cover 240\text{ cm}^2240 cm 2 of his skin. he assumes the relationship between milliliters of sunscreen and area is proportional.

Kwesi needs 16 ml or 16 g of sunscreen to cover 240 cm² of his skin.

Step-by-step explanation:

It is given that Kwesi is putting on sunscreen. He uses 3 ml to cover 45 cm² of his skin.

Let Kwesi needs x ml of sunscreen to cover 240 cm² of his skin.

It is given that relationship between milliliters of sunscreen and area is proportional.

Divide both sides 45.

We know that

Therefore Kwesi needs 16 ml or 16 g of sunscreen to cover 240 cm² of his skin.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
