Answer:
40 min
Step-by-step explanation:
As unitary method
3.6 miles in 30 min
1 miles in (30÷3.6)=8.333 min
Then
4.8 miles in (4.8×8.33)=40 min.
So to cover 4.8 miles i will take 40 min..
Answer:
x=52
Step-by-step explanation:
90+34
124
180 (sum of all interior angles) - 124
56
x+72+56=180 (straight line)
x+128=180
-128 -128
x=52
*replace to verify*
52+72= 124
124+56= 180 (straight line)
I believe the answer is c
X= 30/r is the answer because if you divide both sides by r you are left with x=30/r because you cant divide 30 by r
Answer:
-6
Step-by-step explanation:
Let x =1
F(x)=-x^3-2x^2+7x-10
F(1) = - (1)^3 -2(1)^2 +7(1) -10
= -1 -2 +7-10
= -3+7-10
=-6
