Answer:
it depends on what type of track, and who you are. so if its me and if its a typical quarter-mile track, it would be about a minute and 15 max. then multiply that by 20 and and yod have 25 minutes for 20 laps aka 5 miles
Step-by-step explanation:
Answer:
She could plant 9 plants.
Step-by-step explanation:
1 1/2 hours = 90 minutes, so 12 plants per 90 minutes. Which would mean 6 plants per 45 minutes. So in between 45 and 90 minutes (1 hour), and in between 6 and 12 plants (9).
Sorry if you didn't understand, I'm bad at explaining.
Answer:y=12
Step-by-step explanation:
If this is just factoring, x^2 + x - 90 turns into this:
(x - 9)(x + 10)
If your trying to solve for x, we take the factored expression and set it equal to 0.
(x - 9)(x + 10) = 0
Set each binomial into two equations.
x - 9 = 0 and x + 10 = 0
Solve for x and we get two answers.
x = 9
x = -10
We know that perimiter is
p=2legnth+2width
the equation they gave us is
p=2(2w)+2w
so we know that 2(2w)=2legnth so 2w=legnth
so p=2(2w)+2w
p=4w+2w
p=6w
A. we were not given specific legnths so this is false
B.the perimiter is 6 times the legnth p=6w so this is the answer
C. we were not given specific legnths so this is false
D. this is false because perimeter is 6 times the width
the answer is B
