There are 10 students. 30% of the students returned their calculators at the end of class. How
many students returned their calculator at the end of class?

Answers

Answer 1
3 because 10% of 10 is 1 times by 3 fir 30% is 3 students
Answer 2
Answer: 3

We can find 10% by dividing the number of students by 10.
10/10 = 1

We need to work out 30%, and we already have 10% so we just multiply 10% by 3.
1 x 3 = 3
So 30% = 3

Therefore, 3 students retuned their calculator at the end of class.

The scale on a map is 1 inch = 14 miles. The measurement between two cities on the map is 7 inches. What is the distance between the two cities?

Answers

Given:

The scale on a map is 1 inch = 14 miles.

The measurement between two cities on the map is 7 inches.

To find:

The actual distance between the two cities.

Solution:

We have,

1 inch = 14 miles

Multiply both sides by 7.

7×1 inch = 7×14 miles

7 inch = 98 miles

The measurement between two cities on the map is 7 inches and using the given scale, we get 7 inch = 98 miles.

Therefore, actual distance between the two cities is 98 miles.

four pieces of pie were eaten from a pie cut into equal parts. The 5 pieces that remained created an angle that measured 200°. What was the angle measure of one piece of pie

Answers

Step-by-step explanation:

The 5 pieces that remained created an angle that measured 200 degree means that the 4 pieces made 360-200 degrees 160o.

If all four made 160 then each has to be 160/4 = 40o

200/5 also gives you 40 (the five remaining)

360/9 would also give you 40 9the 5 remaining and the 4 eaten)

Answers

Answer:

8192

Step-by-step explanation:

The pattern here is that each term multiplied by 4 is the next number. You can keep multiplying by 4 until you reach the 7th term. So the 5th term will be 128x4 = 512. The 6th term will the 512x4 = 2048. And finally, the 7th term will be 2048x4 = 8192.

Answers

Answer: -4/5

Step-by-step explanation: It's important to understand

that perpendicular lines have negative reciprocal slopes.

"Negative reciprocal" is just a fancy way

of saying flip the fraction and change the sign.

So if we flip the fraction 5/4 we get 4/5 and

if we change the sign we get -4/5.
