To win a game, you need at least 45 points. Each question is worth 3 points. Write and solve an inequality that represents the number of questions you need to answer correctly to win the game.

Answers

Answer 1

Answer:

Answer:

$3x\geq 45$ ; At-least 15 questions.

Step-by-step explanation:

Let x represent the number of questions you need to answer correctly..

We have been given that each question is worth 3 points. The points earned from answering x right questions would be $3x$ .

Since we need at-least 45 points to win the game, so points earned from answering x questions would be greater than or equal to 45. We can represent this information in an equation as:

$3x\geq 45$

$(3x)/(3)\geq (45)/(3)$

$x\geq 15$

Therefore, you need to answer at-least 15 questions correctly to win the game.

Answer 2

Answer: 3x=45
(divide each side by 3)
x=15
You need to answer 15 correctly.

What is the volume of the rectangular prism?

Let the prism with a length of L, a width of W, and a height of H. Then the volume of the prism is given as

V = L x W x H

Water weighs about 62 pounds per cubic foot. The pond is 6 feet long and 4 feet wide. If the water pond is 2 feet deep. Then the volume of the water pond is calculated as,

V = L x W x H

V = 6 x 2 x 4

V = 48 cubic feet

Then the weight of the water in the pond will be given as,

W = 62 x 48

W = 2,976 pounds

The volume of the pond is 48 cubic feet. Then the weight of the water in the pond will be 2,976 pounds.

a veterinarian purchases some medication for $19.50 and wants to make a $2 profit. what is the percent markup on this medication

Answers

so he has to sell it at 19.5+2=21.5 dollars

so assume19.5=100%
the markup is 2 dollars
2=x%
find x if 19.5=100%

so since they are proportionite
19.5:100 and 2:x
if we make them fractions and flip one of them then multiply we will get 1 since
2/4=1/2
2/4 times 2/1=4/4=1 so

19.5/100 times x/2=19.5x/200=1
19.5x/200=1
multiply both sides by 200
19.5x=200
divide both sdies by 19.5
x=10.256 aprox
x=10.3% markup
