31,680 feet per hour.
There are 5280 feet in a mile, so 6(5280)=31,680
Answer:
10 feet
Step-by-step explanation:
- Multiply 20 by 6 which will give the answer 120 (in inches).
- Then convert 120(inches) to feet by dividing with 12.
- The answer will be 10(feet) needed for six shelves.
20x6= 120
120/12=10
=10 ft
Answer:
(-8,8)
Step-by-step explanation:
It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)
Let x be the width of the room. I<span>f the width is 3.5 feet less than the length, then the length is x+3.5. The perimeter is x+x+x+3.5+x+3.5=4x+7.
</span>
Since the perimeter is equal to 67, then 4x+7=67, 4x=60, x=60÷4, x=15 ft and x+3.5=15+3.5=18.5 ft.
Answer: the width is 15 ft, the length is 18.5 ft.
