Answer:
80 minutes
Step-by-step explanation:
We can solve this problem using rule of three:
The ratio of number of minutes and number of miles is 24 to 3, that is, for each 24 minutes running, she runs 3 miles.
So, if to run 3 miles she needs 24 minutes, to run 10 miles, how much time she will need:
3 miles -> 24 minutes
10 miles -> X minutes
3/10 = 24/X
X = 10 * 24 / 3 = 80 minutes.
She will take 80 minutes to run 10 miles.
I might not be correct but i think Perimeter=31. Since the problem tells me that the area is 42 square inches i divided the given area (42 inches) by the given side length (12 inches), and I got 3.5. I did this because the formula for area is a=lw therefore 12×3.5=42 inches. Now that I know the missing measurement of the other side length, I can plug the numbers I have into either one of these equations.
P=SIDE++SIDE+SIDE+SIDE OR P=2(length)+ 2(width). Please let me know whether or not you understand or have any other questions I will be more than happy to answer. Later when you reach 9th grade and become a freshmen you will learn theorems that will help make it a little bit easier and they will also remove A LOT of the algebraic work that's required to solve questions such as this one. My name is Takira and I go to LaGuardia High School for Performing Arts. Please let me know if you have any more questions.
If i understand your question completely its 7/12 of the yard because 21/36 is simplified to 7/12.<span />
Answer: y=0
Step-by-step explanation:
The y axis or the ordinate(my bad for the mis-spelling) cuts is the line of symmetry for this shape, so to 'highlight' that line you have to say y=0
