Answer:

The answer is 7.

Step-by-step explanation:

You have to substitute the value of x into the function :

$f(x) = \sqrt{x - 8} + 3$

$f(24) = \sqrt{24 - 8} + 3$

$f(24) = \sqrt{16} + 3$

$f(24) = 4 + 3$

$f(24) = 7$

Jill and Erika made 4 gallons of lemonade for their lemonade stand. How many quarts did they make if then charge $2:00 per quart

notka56 [123]

Answer:

Number of quarts=16

Money earned=$32

Step-by-step explanation:

Given

4 Gallons of lemonade is prepared
They charge $2 for a quart

1 Gallon= 4 Quarts

Therefore Number of quarts

$= \text{number of gallons} \times 4\\= 4 \times 4\\=16$

Therefore Number of quarts of lemonade prepared by them = 16 quarts

As they charge $2 for each quart

⇒

Total money made if they sell it all

$=\text{number of quarts} \times 2\\= 16 \times 2\\=32$

Therefore, if they are to sell all the lemonade that they prepared

They would earn=$32

How do you solve this using substitution method 17x+7y=20 Y=20x-42

Nutka1998 [239]

Answer:

17 x + 7 y = 20

y =20x - 42

17 x + 7(20x - 42) = 20

17x + 140x - 294 = 20

157 x = 20 + 294

157x ÷ 157 = 314 ÷ 157

x = 2

y = 20x - 42 

y = 20 (2) - 42

y = 40 - 42

y = -2

there for x = 2 and y = -2 is the solution

The formula for volume is Length x width x height.

Bottom: 18 * 12 * 8 = 1728 cubic centimeters.

Middle: 12 * 8 * 6 = 576 cubic centimeters.

Top = 4 *4*4 = 64 cubic centimeters.

Total: 1728 + 576 + 64 = 2368 cubic centimeters.

in a circle, a 60° sector has an area of a 36π cm^2. find the radius of the circle. round your answer to the nearest whole centi

hammer [34]

Area of circle = $\frac{ \theta }{360^o} \times \pi r^2 \\ 36 \pi = \frac{60^o}{360^o} \times \pi r^2 \\ r^2=216 \\ r= \sqrt{216} =14.70 \ cm \\ r=15 \ cm \ to \ the \ nearest \ whole \ centimeter.$
