Answer:
33.45
Step-by-step explanation:
Just multiply
Just put it like normally, forget the decimal for now, you don’t have to line it up due to it not being addition Or subtraction
You’ll get 3345 without the decimal
now there are 2 decimal places from 0 so
just move the decimal place 2 times to the left
33.45
Answer:
Step-by-step explanation:
Remark
The angles are marked as alternate interior angles. To be parallel, they must be equal. In other words x - 20 must equal 52. That's all you have to do. Just equate the 2 givens and solve.
Givens
x - 20 is one angle
52 is the other.
Solution
x - 20 = 52 Add 20 to both sides.
x - 20 + 20 = 52 +20 Combine
x = 72
Answer: C
It’s D, I graphed on a calculator and the line was straight
Answer:
C. Amplitude = 3 feet; period = 8 hours; midline: y = 4
Step-by-step explanation:
The midline is halfway between the lowest point and the highest point.
y = (1 + 7) / 2
y = 4
The period is the time it takes for a full cycle. So the period is 8 hours.
The amplitude is the distance from the midline to the lowest or highest point.
a = 4 − 1 = 3, or a = 7 − 4 = 3
It's also half the distance between the lowest and highest points.
a = (7 − 1) / 2
a = 3
