Express the answer in terms of π .

Answers

Answer:

36π mm

Step-by-step explanation:

The arc length formula is s = rФ, where Ф is the central angle (in radians).

If r = 48 mm and Ф = 3π/4, then the arc length is:

s = rФ = (48 mm)(3π/4) = 36π mm

Fran is struggling with her priorities for the next few weeks: homework due tomorrow, an essay due in two weeks, a research outline due by the end of the week, and a test next week. How should she list her priorities, starting with the most important task?

Answers

Answer:

C

1. homework

2. research outline

3. test

4. essay

Step-by-step explanation:

The tasks will be prioritized based on the ones with the closest date to today.

Her homework due tomorrow, therefore it is the first priority.

Her research outline due by the end of the week, therefore it is the second priority.

She has a test next week, and therefore it is the third priority.

Then finally, in 2 weeks, she has an essay and as such it should be the fourth priority.

The only option that has these tasks arranged in the correct order of priority based on the most important tasks as I have listed is Option C.

6th grade work fast and easy

Answers

Answer: 56 times

Step-by-step explanation:

If his ratio of goals to misses is

6:7

then we must find out how many times he missed seeing he scored 48

so

48:?

to solve find out if 6 goes into 48 and it does 8 times so multiply both sides by 8 to get the new ratio

6*8:7*8

48:56

So the new ratio is 48:56 which also means he missed 56 shots

what is 6 divided by 1,932

Answers

Step-by-step explanation:

do u mean 1,932 divided by six?

Answer:

1932 divided by 6 in decimal = 322

1932 divided by 6 in fraction = 1932/6

1932 divided by 6 in percentage = 32200%

Step-by-step explanation:

The number 1932 is called the numerator or dividend, and the number 6 is called the denominator or divisor.

The quotient of 1932 and 6, the ratio of 1932 and 6, as well as the fraction of 1932 and 6 all mean (almost) the same:

1932 divided by 6, often written as 1932/6. 1932 divided by 6 = 322

The result of 1932/6 is an integer, which is a number that can be written without decimal places.

1932 divided by 6 in decimal = 322

1932 divided by 6 in fraction = 1932/6

1932 divided by 6 in percentage = 32200%
