Answer:

B. -19 4/3

Step-by-step explanation:

Opposite numbers add to 0.

For example, -1 and 1 are opposite since -1 + 1 = 0

Let's say x is the answer:

19 4/3 + x = 0

19 4/3 - (19 4/3) + x = 0 - (19 4/3) => subtract 19 4/3 on both sides to isolate x

0 + x = -19 4/3

x = -19 4/3 ==> Answer is B

In a city, there are 16 swimming pools. On weekends, 6 of the pools are open.
George says the ratio of pools open on weekends to the total number of pools is 6:16.
Emma says the ratio of pools open on weekends to the total number of pools is 6:11.

Which student is correct? Explain.

Answers

Answer:George

Step-by-step explanation: George is correct because Emma said that the total number of pools in the city is 11 even though it says there are 16 pools in the city, but she got the number of how many are open, George is right because it says what is the ratio of pools open on the weekends to the total amount of pools, and it says there are 6 pools open on the weekend and there are 16 pools in the city in total so he would do 6:16.

George is correct they said that the ratio of pools open on weekends to the total number of pools is 6:16.

What are ratios and proportions?

A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other. For example, if there is one boy and three girls, the ratio could be written as 1: 3. (for every one boy there are 3 girls) One-quarter are boys and three-quarters are girls.

Given that In a city, there are 16 swimming pools. On weekends, 6 of the pools are open.

George says the ratio of pools open on weekends to the total number of pools is 6:16.

Emma says the ratio of pools open on weekends to the total number of pools is 6:11.

George is right that the ratio of the open pools to the total pools will be 6:16.

The circle graph describes the distribution of preferred transportation method from a sample of 300 randomly selected San Francisco residents. circle graph titled San Francisco Residents' Transportation with five sections labeled walk 40 percent, bicycle 8 percent, streetcar 15 percent, bus 10 percent, and cable car 27 percent Which of the following conclusions can be drawn from the circle graph? Cable Car is the preferred transportation for 75 residents. Bicycle is the preferred transportation for 30 residents. Together, Streetcar and Bus are the preferred transportation for 25 residents. Together, Bus and Bicycle are the preferred transportation for 54 residents.

Answers

The following conclusions can be drawn from the circle graph:

Cable Car is the preferred transportation for 75 residents. (27% of 300 = 81 residents)

Together, Streetcar and Bus are the preferred transportation for 25% of residents. (15% + 10% = 25% of 300 = 75 residents)

The other two statements are incorrect:

Bicycle is the preferred transportation for 8% of residents, not 30. (8% of 300 = 24 residents)

Together, Bus and Bicycle are the preferred transportation for 18% of residents, not 54. (10% + 8% = 18% of 300 = 54 residents)
