If blueberries cost $4.00 per pound, how many pounds of blueberries can you buy for $1.00?

Masteriza [31]

If x is the number of berries you can buy with 1 dollar,

1 pound of blueberries = $4.00

x pound of berries = $1.00

Lets set up a proportion- because these are directly proportional- when there is more pounds of berries, it will cost more.

$\frac{1}{4.00} = \frac{x}{1.00}$

Cross multiply

4x=1

Divide both sides by 4 to isolate x

x=1/4 or $0.25

PLEASE HELP! NO ONE HAS BEEN HELPING WITH MY QUESTIONS SO IT WOULD MEAN A LOT IF YOU DID!

Answer:

80 m²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h (a + b)

where h is the perpendicular height between bases and a, b are the bases

Here h = 8, a = 14 and b = 6, thus

A = $\frac{1}{2}$ × 8 × (14 + 6) = 4 × 20 = 80 m²
