Answer:
Mai
Step-by-step explanation:
To find the rate, you must determine who is going faster per minute. To do this, you must divide the total number of miles by the total number of minutes.
Mai: 5 miles / 15 minutes = 1/3 miles per minute
Jada: 4 miles / 14 minutes = 2/7 miles per minute
Then, use a common denominator to make calculations easier:
Mai: 1/3 * 7/7
Jada: 2/7 * 3/3
You should get:
Mai: 7/21 miles per minute
Jada: 6/21 miles per minute
By looking at this, you can see that Mai is traveling slightly faster, going more miles than Jada per minute.
If m1 and m2 are the slopes of each line, for them to be perpendicular you gotta solve
m1 * m2 = -1
Answer:
13-gon
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides is:
S = 180° (n − 2)
If S = 1980°, then:
1980° = 180° (n − 2)
11 = n − 2
n = 13
Answer:
12
Step-by-step explanation:
a=3b
b=2c
c=4d
a*c/b*d = (3(2(4d)))*(4d)/(2(4d))*d
= 96d^2/8d^2
= 12
