Meredith is playing games at an arcade to earn tickets that she can exchange for a prize. She has 255 tickets from a previous vi

aliya0001 [1]

Answer:

20 games.

Step-by-step explanation:

Given:

Meredith is playing games at an arcade to earn tickets that she can exchange for a prize.

She has 255 tickets from a previous visit.

She earns 6 tickets for each game she plays.

Meredith needs 375 tickets to exchange for the prize she wants.

Question asked:

How many games does Meredith need to play?

Solution:

Total tickets needed to exchange for the prize = 375

Meredith already have = 255 tickets

More tickets needed = 375 - 255 = 120 tickets

By unitary method:

She earns 6 tickets by playing = 1 game

She earns 1 ticket by playing = $\frac{1}{6}$ game

She earns 120 tickets by playing = $\frac{1}{6}\times120=\frac{120}{6} =20\ games$

Therefore, she needs to play 20 games to earn 120 more tickets.

In combining like terms, what do these equations equal?

tester [92]

Answer:

Look below. The answers are bolded!

Step-by-step explanation:

1. 10x + 23

5+6(2x+3)-2x

Distribute first!

5 + 12x + 18 -2x.

Now you can combine like terms.

23 + 10x

2. 18x + 6

3(4x+8) + 3(2x-6)

Distribute first!

12x + 24 + 6x - 18

Now you can combine like terms.

18x + 6

3. -2x + 8

(32-8x)

____ ___

Divide 32 and -8x by 4.

32/4 = 8

-8x/4 = -2x

-2x + 8

4. 4x + 3

24x+18

______

Divide 24x and 18 by 6

24x/6 = 4x

18/6 = 3

4x + 3

Find the distance between the points (5, -6) and (-1, 3).

emmasim [6.3K]

Answer:

$\sqrt{117}$

Step-by-step explanation:

Use the distance formula.

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

$d = \sqrt{(-1 - 5)^2 + (3 - (-6))^2}$

$d = \sqrt{(-6)^2 + 9^2}$

$d = \sqrt{36 + 81}$

$d = \sqrt{117}$

The volume of a sphere is 288pi cm^3 What is the radius of the sphere?

Otrada [13]

Answer:

radius = 6 cm

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = $\frac{4}{3}$ πr³ ← r is the radius

Given V = 288π, then

$\frac{4}{3}$ πr³ = 288π

Multiply both sides by 3 to clear the fraction

4πr³ = 864π ( divide both sides by 4π )

r³ = 216 ( take the cube root of both sides )

r = $\sqrt[3]{216}$ = 6

Thus the radius of the sphere is 6 cm
