Step-by-step explanation:

For a school fundraiser, Percy bought a big box of rubber ducks and wrote prize amounts, in dollars, on the bottom of each rubber duck. The prize amounts were $5, $10, $20, $50, and $100. The number of ducks with each prize amount varied so that the total value for all the ducks with each prize amount was always $500.

Percy then put all the rubber ducks in his school’s swimming pool. At the fundraiser, participants used a long net to catch a duck from the pool. They won the amount written on the bottom of the rubber duck, and then they threw the duck back into the pool before the next person’s turn. Since the ducks were returned to the pool after they were caught, the chances of winning any particular amount remained the same.

Answers

Answer:

$50 for Brian

$90 for Tim

$100 for Kenny

Step-by-step explanation:

Let 5x = amt for Brian

     9x = amt for tim

     10x = amt for ken

5x + 9x + 10x = 240

24x = 240

x = 10

5x = 5(10) = $50 for Brian

9x = 9(10) = $90 for Tim

10x = 10(10) = $100 for Kenny

Answer:

Step-by-step explanation:

5x + 9x + 10x = $240

x = $10

Brian got 5x = $50

Tim got 9x = $90

Kenny got 10x = $100

A playground is rectangular with a length of 12 miles. If the area of the playground is 58 square miles, what is its width? Input your answer as a fraction.

Answers

ABC is a straight line. Work out the size of the angle marked x

Answers

Answer:

x = 57°

Step-by-step explanation:

angles on a straight line add up to 180°. to work out x, we need to subtract 70 and 53 from 180, to get the remaining angle, aka angle x. 180-70=110.

110-53= 57. therefore, x = 57°.

The measure of angle x in the straight line ABC is 57 degrees

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

From the diagram:

x + 53 + 70 = 180° (sum of angles in a straight line).

Hence:

x = 57°

The measure of angle x in the straight line ABC is 57 degrees
