What is 55 percent of 160?
Maurinko [17]

Answer: 88

Step-by-step explanation: To find 55% of 160, first write 55% as a decimal by moving the decimal point two places to the left to get .55.

Next, the word "of" means multiply, so we have (.55) x (160).

(.55) (160) = 88

Therefore, 55% of 160 is 88.

Points A, B, and C are collinear. Point B is between A and C. Find the length of of segment AC if the measure of segment AB= 8 a
RoseWind [281]

Answer:

The value of the length of AC is 14

Step-by-step explanation:

When points are collinear, it simply means that the points lie on the same straight line.

In this question , we have three points which lie on same straight line.

These are points A, B and C with B between A and C.

Thus the length AC can be obtained by adding the length of AB to the length of BC

Mathematically, the value of the length of AC will be 8 + 6 = 14
