Answer:

Change two-thirds to a decimal and then multiply the decimal and your number. To convert 2/3 to decimal, divide the numerator by the denominator: 2 / 3 = 0.66666 ... 7, which you can round to 0.67. For example, to find 2/3 of 21: 0.67 * 21 = 14.07.

39. Find the length of each arc shown in red. Leave your answer in simplified radical form.

andre [41]

Answer:

The length of the arc shown in red is $\frac{22}{9}\pi\ in$

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference is equal to

$C=2\pi r$

we have

$r=4\ in$

substitute

$C=2\pi (4)$

$C=8\pi\ in$

step 2

Find the length of the arc in red

Remember that the length of the circumference subtends a central angle of 360 degrees

by proportion find the length of the arc by a central angle of 110 degrees

$\frac{8\pi}{360}=\frac{x}{110}\\ \\x=8\pi*110/360\\ \\x=\frac{880}{360}\pi\ in$

Simplify

$\frac{880}{360}\pi=\frac{22}{9}\pi\ in$

If Susie is 14, what was her age x years ago?<br><br> x - 14<br> 14 - x<br> 14x

andreyandreev [35.5K]

The answer is 14 - x.

If she is 14 now, and the question is looking for her age x years ago, it is basically just asking you to subtract x from 14.

It also can't be x - 14, because that means Susie's age is x and the question is asking for her age 14 years ago, and it can't be 14x, because that's 14 multiplied by x.
