Answer:
20 mph
Step-by-step explanation:
First problem:
The new speed is 26 mph.
The old speed was x.
The new speed is 30% higher than the old speed.
1.3x = 26
x = 20
Answer: 20 mph
Second problem:
A number, perhaps a percent or a fraction, is missing from the problem.
Answer:
The correlation coefficient is close to -1. There is a strong negative correlation between the amount of time spent working out and the amount of weight lost.
Step-by-step explanation:
I did it on USATestprep. -0.9547 is close to -1. This indicates a strong negative correlation. When the workout time increases, Jason's weight decreases.
Here's a really cool website that let's you input 3D points!

From the attached picture you can see that the point has moved back 5 units, to the left 5 units, and up 5 units.
Answer:
53
Step-by-step explanation:
58÷1.095= 53 is the answer
2x + 2x + 32 = 256
-32
2x+2x = 224
4x=224
/4
x= 56
lenght = width+16
perimeter = width + width + (width + 16) + (width + 16)
perimeter = x + x + (x+16) + (x+16)
perimeter = 2x + 2((x+16)
therefore width = 56
length = 72
