Answer:
Amelia drove 90 miles in 3 hours.
Step-by-step explanation:
she drove 10 miles in 20 minutes
we multiply this by 3, and get
30 miles in an hour ( 60 minutes)
then we multiply this by 3 and get
90 miles in 4 hours (180 minutes) :)
x
factor out both equations and then cancel any of the common factors. You should be left with 4x/4, which simplified is x
Use Pythagoras theorem
Hypotenuse²=Base²+ Height ²
H²=(8)²+(6)²
H²=64+36
H²= 910
H²=10√91 cm Solution
we have that
Let
we know that
so
Is a geometric sequence
Find the value of
Find
therefore
the answer is
