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

100= queen rooms

>:(

Answers

Answer:

I think it may be 14.1593% or something around that. If not, forgive me.

The percent error of the measurement, to the nearest tenth of a percent, will be 14.16%.

What is the error percentage?

The amount of error is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

In 1846 the depth of the river was 2.5 feet deep. In 1847 it rose 9%. This year, 1848, it dropped 6%. How deep is the river now?

Answers

Answer:

So the answer is 2.5615 feet.

Step-by-step explanation:

So the river is 2.5 feet deep, and when you find that 9% is, using the cross-multiplication formula to find the percent then 9% of 2.5 is 0.225, and when you add that to 2.5 you get 2.725, and when you find 6% of 2.725, you get 0.1635, and since it dropped, you subtract, and you end up with 2.5615

Hope I helped

The depth of the river in 1848 is 2.5615 feet.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

The % formula is used to calculate a percentage of a whole in terms of 100. You may use this formula to express a number as a fraction of 100. If you look closely, calculating percentages indicated above can be readily computed using the formula below:

Percentage = (Value/Total Value) × 100

To solve this problem, we can start by finding the depth of the river in 1847 after it rose by 9%.

Depth in 1847 = 2.5 + (9% of 2.5)

Depth in 1847 = 2.5 + 0.225

Depth in 1847 = 2.725 feet

Next, we need to find the depth of the river in 1848 after it dropped by 6%.

Depth in 1848 = 2.725 - (6% of 2.725)

Depth in 1848 = 2.725 - 0.1635

Depth in 1848 = 2.5615 feet

Therefore, the depth of the river in 1848 is 2.5615 feet.
