Answer:

I think the answer is 171.

Step-by-step explanation:

Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)

I am pretty sure this is right...I hope this helps!

A circle has a radius of 5 in. A central angle that measures 150° cuts off an arc.

marishachu [46]

Answer:

Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in

Part 2) The approximate value of the arc length is 13.1\ in

Step-by-step explanation:

ind the circumference of the circle

The circumference of a circle is equal to

C=2\pi r

we have

r=5\ in

substitute

C=2\pi (5)

C=10\pi\ in

step 2

Find the exact value of the arc length by a central angle of 150 degrees

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

by proportion

\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in

Find the approximate value of the arc length

To find the approximate value, assume

\pi =3.14

substitute

\frac{25}{6}(3.14)=13.1\ in

Mariana is taking a multiple choice test with a total of 80 points available. Each question is worth exactly 4 points. What woul

Sladkaya [172]

Mariana's score if got right if she got 5 wrong is 60 points.

Mariana's score if got right if she got xx wrong is 80 - 4xx.

<h3>What is Mariana's score?</h3>

The first step is to determine the number of questions that Mariana got right. In order to get the number of questions that she got right, subtract the total number of number of questions from the questions that he got wrong.

Questions that Mariana got right = total number of questions - questions he got wrong

Total number of questions = total number of points / point of each question

Total number of questions = 80 / 4

Total number of questions = 20

Questions that Mariana got right if he got 5 wrong = 20 - 5 = 15

Mariana's score = questions she got right x number of points per question

Mariana's score = 15 x 4 = 60 points

Questions that Mariana got right if he got x wrong = 20 - xx

Mariana's score = (20 - xx) x 4

Mariana's score = 80 - 4xx
