Answer:
(A) 1
(B) -2
(C) 3.5
(D) -0.5
Step-by-step explanation:
We can treat each thermometer like a vertical number line and read the values on each.
A is right on 1.
B is right on -2.
C is in the middle of 3 and 4, so 3.5
D is in the middle of 0 and -1, so -0.5
Hope this helped!
Since GH bisects CF, therefore:
CD = (1/2) CF
3y - 11 = (1/2) (2y -2) (multiply both sides by 2)
6y - 22 = 2y - 2
6y - 2y = -2 + 22
4y = 20
y = 5
Substitute with the value of y in the equation of CD, you get:
CD = <span>3y-11 = 3(5) - 11 = 15 - 11 = 4 cm</span>
Answer:
c
Step-by-step explanation:
absolute value of -15 is 15, 15 us more than 10
Answer:
It's a proportion.
2 is to x as 15 is to 9, or 2/x = 15/9.
Multiply the means and extremes
15x = 18
divide both sides by 15 to get x by itself.
x = 1.2

Answer:
4 seconds
Step-by-step explanation:
where h=height reached after t seconds
= Initial Height of the ball
The ball is dropped from a height of 205 feet,
= 205 feet
We want to determine the time it takes the ball to reach the ground.
i.e. when height of the ball, h=0
Substituting = 205 feet and h=0 into the formula
Add 
to both sides
Divide both sides by 16
≈ 4 Seconds
It takes approximately 4 seconds for the ball to reach the ground.
