The area of a rectangle is 47.5 square centimeters. The
base of the rectangle is 5 centimeters. What is the height of
the rectangle in centimeter?

Answers

Answer 1
SHORT ANSWER: 84cm

Let width = w

Let length = w + 5

The area of a rectangle is found by multiplying its width by length and the problem states that the area is 84 cm2.

(Width)(Length) = 84

(w)(w + 5) = 84

w2 + 5w = 84

w2 + 5w - 84 = 0

(w + 12)(w -7) = 0

w + 12 = 0

w = -12

The width of a rectangle can't be NEGATIVE!!! Forget about that!

w - 7 = 0

w = 7

Now go back to naming the variables and replace the w with 7.

Length = w + 5 = 7 + 5 = 12

Width is 7 cm. Length is 12 cm.

Check it. Is 7 x 12 = 84? Yes.

If two sweaters and four shirts cost $150, and four sweaters and three shirts cost $200, find the price of each shirt and each sweater.

Answers

Answer:

shirt = $20

sweater = $35

Step-by-step explanation:

This question would be solved using simultaneous equation

Let the price of sweater be represented by a

Let the price of shirt be represented by b

The following equations can be derived from the question

2a + 4b = 150   equation 1

4a + 3b = 200   equation 2

Multiply equation 1 by 2

4a + 8b = 300    equation 3

Subtract equation 2 from 3

5b = 100

divide both sides of the equation by 5

b = 20

substitute for b in equation 1

2a + 4(20) = 150

2a + 80 = 150

collect like terms

2a = 150 - 80

2a = 70

divide both sides by 2

a = 35

Price of sweater = $35

Price of shirt = $20

A grocery store stocks different flavors of peppermint sticks in 15 jars. The number of sticks in each jar varies from 0 to 49. Suppose you are creating a histogram to represent the situation. A. Which axis should be labeledas the num ber of jars for each flavor? B. What are possible intervals that COULD be appropriate for the histogram?

Answers

Answer:

The correct answers are:

A. The Vertical axis should be labelled as the Number of Jars for Each Flavour

B. an interval of 7 could be appropriate

Step-by-step explanation:

A. The number of jars for each flavour is the dependent variable against the flavour type, which is the independent variable, hence it is displayed on the vertical axis to show the height of the bars.

B. since the number of sticks in a jar vary from 0 to 49, dividing 49 by 7 will give 7 without a remainder, hence, an interval of 7 will be ideal for the plot, nd a total of 7 bars will be plotted. Intervals are: 0-7, 8-14, 15-21, 22-28, 29-35, 36-42, 43-49.

Three teachers buy prizes to put in the prize bin at school. Mrs. Maiers spends $7.68 on stickers. Mr. Lang spends $11.52 on balloons. Mrs. Connor spends $17.64 on pencils.

Answers

Answer: $12.28

Step-by-step explanation:

Here's the complete question:

Three teachers bought prizes to put in a bin at school. Mrs. Maier spent $7.68 on stickers. Mr. Lang spent $11.52 on balloons. Mrs. Connor spent $17.64 on pencils. The teachers divided the cost evenly. How much did each teacher pay?

Cost of stickers = $7.68

Cost of balloons = $11.52

Cost of pencils = $17.64

Total spent = $7.68 + $11.52 + $17.64 = $36.84

The amount that each teacher will pay when the total cost is evenly shared will be:

= $36.84 / 3

= $12.28
