Just Need A Little Help And Explanation On This One. I Always Mess Up And Get Confused, Which Causes

Answers

Answer 1
first you will convert -2 1/3 to an improper fraction which will leave you with -7/3 - (-5) then you remove the parentheses which will change -7/3 - -5 to -7/3+5 since two negatives = a positive. Then make the denominators the same by multiplying 5 by 3, then you have -7+15
———
3

then you will subtract -7+15 to get you
8/3 and then simplify the improper fraction to get the difference of 2 2/3

your final answer is 2 2/3

Answers

45(x)-20

x=hours

7 hours

x=7

45(7)-20 =295

Answer:

y = 45(7) - 20

Step-by-step explanation:

Money earned: 45x.

Money spent: 20

Total money: 45x-20

A hotel has a total of 172 rooms. About 58% of the hotel rooms have 2 queen beds in each room and the rest of the rooms have 1 king bed. How many rooms have queen beds?

Answers

Answer:

99.76 = 100

Step-by-step explanation:

Answer:

Queen rooms: 99.76 but since it is a real world problem round it to the nearest tenth

king rooms: 72

Step-by-step explanation:

172 x 58% or 172 x 0.58= 99.67.

rounded = 100.00

172 - 100 = 72

100= queen rooms

72= king rooms

Find the area of the rectangle with measurements shown; reduce to lowest terms:
Length: 1 4/5 feet; Width: 1 5/8 feet
1 1/8 feet
2 37/40 square feet
1 5/40 square feet.
1 1/8 square feet

Answers

The area of the rectangle given is: B. 2 37/40 square feet.

What is the Area of a Rectangle?

Area of rectangle = length × width.

Given:

Length = 1 4/5 = 9/5 feet

Width = 1 5/8 = 13/8 feet

Thus:

Area of Rectangle = 9/5 × 13/8

Area of Rectangle = 117/40

Area of Rectangle = 2 37/40 sq. ft

Therefore, the area of the rectangle given is: B. 2 37/40 square feet.

Do 2 or more shapes with the same perimeter have to have the same area? Explain with examples. AND Do 2 or more shapes with the same area also have to have the same perimeter? Explain.

Answers

Yes. Take for example a square and an ellipsis with the same perimeter. The family of ellipses with the same perimeter can have any area between that of a circle to zero (if it is extremely “thin” i.e. if its eccentricity is large). The circle has the maximum area of any other shape with the same perimeter, so the square has the same area of one of the intermediate ellipses.

13) A football team completed three passes for 18 yards each and two runs for 12 yards each, but was also assessed four penalties which cost them 5 yards each. Write a numerical expression which would determine how many yards they have gained or lost.

Answers

Answer

18(2)+12(2)-4(5)

36+24-20

60-20

40

Step-by-step explanation:

since they had two-18 yard passes and two 12 yard runs, that's the first part of the expression, and then they had four penalties that cost them 5 yards, and that was the last term. When you simplify, you end up with 40 yards gained.

In math

Passes: 18(2)

Runs: 12(2)

Penalties:4(5)

equation

18(2)*12(2)-4(5)

Hope it helped

18(2)+12(2)-4(5)

*PLEASE SHOW YOUR WORK

940,000 is your answer
You have to divide 135 from 540,000 and then multiply 100. Which is 400,000.
