At a store there are 5 vases each vase has the same number of flowers 16 flowers are sold now there are 24 flowers left how many

Drupady [299]

Let f=number of flowers in a vase, then:

5f-16=24 add 16 to both sides

5f=40 divide both sides by 5

f=8

So there were 8 flowers per vase in the beginning.

Find the area of a circle with a circumference of <br> 18.84

Anton [14]

Answer:

9π OR 28.26

Step-by-step explanation:

The formula for circumference is C = 2πr.

Substitute circumference = 18.84 for C.

18.84 = 2πr

Work backwards to find the radius of your circle.

$\frac{18.84}{2(3.14)} =r$

r = 3

Now, use the formula for the area of a circle: A = π $r^2$ .

Substitute r = 3 into the equation:

A = π $3^2$ = 9π ≈ 28.26

The area of a rectangular wall of a barn is 153 square feet. Its length is 8 feet longer than the width. Find the length and wid

r-ruslan [8.4K]

Answer and Step-by-step explanation:

Area (A) = 153

Length (l) = 8 + w

Width (w) = w

A = lw

153 = (8 + w)(w)

153 = $w^{2} + 8w$

0 = $w^{2} + 8w$ - 153

$w^{2} -9w + 17w - 153$

(w - 9)(w + 17)

w = 9

w = -17

We can't have a negative length, so we only use 9.

w equals 9.

That means l equals 17 (9 + 8 = 17).

Length = 17

Width = 9

A car used 16 gallons of gas to travel 240 miles . How many gallons would the car use to travel 180 miles

Nikitich [7]

Answer: 12 gallons

Step-by-step explanation:

The car uses 16 gallons to travel 240 miles. You need to calculate how many miles is in a gallon. So, divide 240 by 16 (you get 15). That is 15 miles per gallon. Next, you divide 180 by 15 to calculate how many gallons it would take you to travel 180 miles if there are 15 miles in a gallon.
