Tatiana [17]

Answer:

35%

Step-by-step explanation:

40% + 25% = 65% minus that bye 100 you would get 35% the reason the answer isn't 65 is because add 40+25+65=130 which a whole is equal to 100 but if you do 40+25+35= 100 so thr answer is 35% :)

What is the average (with 0 decimal places) across all schools for the total score? Group of answer choices 1287 1215 1221 1229

Irina18 [472]

Answer:

See explanation

Step-by-step explanation:

Required

The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

$\bar x = \frac{\sum x}{n}$

Assume the data is:

$1287\ 1215\ 1221\ 1229$

This means that the number of schools is 4

So:

$\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}$

$\bar x = \frac{4952}{4}$

$\bar x = 1238$

The average of the assumed data is 1238

A flying disc has a circumference of 75.36 centimeters. What is the area of the flying disc? (Use 3.14 for .)

Hatshy [7]

The area of flying disk is 452.16 square centimeters

Step-by-step explanation:

The disc is in circular shape so we will use the formulas for circle in this question.

Given

Circumference = C = 75.36 centimeters

We have to find the area of the disc for which we have to find the radius first.

Let r be the radius

Then

Circumference is given by:

$C=2\pi r$

putting the values

$75.36 = 2*3.14*r\\75.36 = 6.28r$

Dividing both sides by 6.28

$\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm$

The area of circle is given by:

$A = \pi r^2$

Putting the values

$A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2$

Hence,

The area of flying disk is 452.16 square centimeters

Kristy makes 5$ per hour babysitting and 12$ per hour giving music lessons. One weekend, she worked a total of 18 hours and made

MariettaO [177]

Let Karen works x hours baby sitting
So, she worked (18-x) hours giving music lessons
So,
According to question
5x + 12(18-x)=139
This gives
7*x=77
x=11
So,
Karen worked 11 hours baby sitting and (18-11)=7 hours giving music lessons
