88 % students of the class hand in their projects on time
<em><u>Solution:</u></em>
Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time
Total number students = 25
Students hand in their projects on time = 22
<em><u>To find: percent of the class hand in their projects on time</u></em>

Substituting the values, we get

Thus 88 % students of the class hand in their projects on time

Answer:
A and B
Step-by-step explanation:
using the law of exponents
•
=
, hence
=

note that (- 3)² = 9 = 3², hence
= (3²)³ =
→ B
Using volume of ball bearings, a manufacturer makes 10 ball bearings from 5.2 cm³ of molten steel to make ball bearings that each have a diameter of 1 centimeter.
According to the question,
It takes 5.24 cubic centimeters of molten steel to make ball bearings that each have a diameter of 1 centimeter.
Radius = 1/2 = 0.5 cm
volume V of one ball bearing is: V=(4/3)*π*r³
= 4/3 * π * (0.5)³
=0.524 cm³
In order to find number of ball bearings out of molten steel only if we divide the volume of steel by the volume of the ball bearing
5.24/0.524=10.
Hence, using volume of ball bearings, a manufacturer makes 10 ball bearings from 5.2 cm³ of molten steel to make ball bearings that each have a diameter of 1 centimeter.

Answer:
D. the segment has two endpoints
Step-by-step explanation:
In math, a line is a mark that goes both ways (opposite directions) indefinitely, or forever. A line segment goes both ways, but also has two endpoints, one at the "beginning" and "end". This means is it only part of a line. All of the other answers are false or void.
