Answer:
1. The correct answer is graph b
2. the correct answer is t>100
Step-by-step explanation:
Answer:
C 9
D 12
Step-by-step explanation:
9 is a corresponding angle to 5 and 12 is an opposite angle to 9
Also by convention, grid lines are at right angles to each other so 5, 6, 7, 8, 9, 10, 11, and 12 are all equal at x = 90°
Answer:
A. 0.72
Step-by-step explanation:
When the ball hits the ground, h = 0.
0 = -16t² + 6t + 4
0 = 8t² − 3t − 2
Solve with quadratic formula:
t = [ 3 ± √(9 − 4(8)(-2)) ] / 16
t = (3 ± √73) / 16
t = 0.72
Answer:
24 people in the history class.
Step-by-step explanation:
Let the total number of people in the class = x. I do this rather a long way because people often have trouble dealing with the division of fractions.
Equation
75/100 * x = 18 Multiply by 100
Solution
75x = 18*100
75x = 1800 Divide by 75
x = 1800/75
x = 24
There are 24 people in the class
