George wants to put carpeting in a rectangular living room and a square bedroom. The length and width of the living room is 12 feet and 18 feet. One side of the square bedroom is 13 feet. It will cost $3.50 per square foot to carpet the rooms. A. Write an expression that can be used to find the total amount George will pay for carpeting. B. Evaluate the expression. How much will George pay for the carpeting?

Answers

Answer 1

Answer: Well, 12x18 = 216 sq. feet and 13x13 = 169 sq. feet. Add that together and that equals 385 sq. feet total. 3.50x385 = 1347.50. So, George will have to pay $1,347.50 to get his living room and bedroom carpeted.

a bar graph shows that sports books received 9 votes. if the scale is 0 to 20 by twos, where should the bar end for the sports books?

Answers

If the scale is 0 to 20 by twos, then it includes bar numbers 0, 2, 4, 6, 8, 10, 12, 14, 16, 18 and 20.

Since the bar graph shows that sports books received 9 votes, then the bar should end in the middle between 8 and 10 (because 9-8=1 and 10-9=1).

Answer: in the middle between 8 and 10

The answer to this question would be: between 8 and 10

In this question, the sports book get 9 votes but the ranges are made by twos which mean only even number will be placed on the track. The closest even number from 9 would be 8(1 number below) and 10(1 number above). So, the bar should be between 8 and 10

A triangle has an area of 45 square units. Its height is 10 units.What is the length of its base?

Answers

Area = (1/2)*base*height

45 = (1/2)*base* 10

45 = base*5

45/5 = base

9 = base

base = 9

The length of the base is 9 units.

Sam is determining the area of a triangle. In this triangle, the value for the height is a terminating decimal, and the value for thebase is a repeating decimal. What can be concluded about the area of this triangle?

Answers

Answer:

The area is rational because the numbers in the formula are rational.

Step-by-step explanation:

All repeating decimals are still rational because they can be expressed as fractions. For example,

$$(1)/(7)=0.\overline{142857}$\end{document}$

So every recurring decimal must be a fraction.

Also every terminating decimal can be represented as a fraction.

0.25 = $(1)/(4)$

So the area is rational because the numbers are rational.

Area = $(1)/(2)$ X Base X Height

Base is Rational and Height is Rational. Hence Area=Rational.

When these rational numbers are substituted into the formula,the area must be rational.

would you describe the situation with a negative number. The Titanic rests at a depth of about 12,000 feet

No, the number would remain positive since you have already mentioned the word "depth". Using a negative umber just wouldn't make sense, nor would it add any beneficial information too the answer.
