Answer:
1 1/7 miles
Step-by-step explanation:
Since Kenny can run 2/7 of a mile in 1/4 of a hour we can multiply 2/7 by 4 and we end up with 1 1/7 miles ran.
Answer:
x=13/2
Step-by-step explanation:
3/4x=4 7/8
x= 4 7/8 divided by 3/4
x=13/2
check
3/4*13/2=39/8
=4 7/8
Answer:
the answer is E
Step-by-step explanation:
hope this helps!
When you represent intervals on the number line, you're including full dots, excluding empty dots, and you're considering numbers highlighted by the line.
In the first case, you've highlighted everything before -2 (full dot, thus included), and everything after 1 (empty dot, excluded). So, the set would be

or, in interval notation,
![(-\infty,-2]\cup (1,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-2%5D%5Ccup%20%281%2C%5Cinfty%29)
In the second case, you are looking for all numbers between -3 and 5. This interval is symmetric with respect to 1: you're considering all numbers that are at most 4 units away from 1, both to the left and to the right.
This means that the difference between your numbers at 1 must be at most 4, which is modelled by

where the absolute values guarantees that you'll pick numbers to the left and to the right of 1.
-circumference is equal to pi×diameter, area is equal to pi×radius^2
-28.26÷3.14=9, 9÷2=4.5, 4.5×4.5=20.25, and 20.25×3.14=63.585
-rounded to the nearest hundredth, the answer is 63.59
