Answer:
64 miles
Step-by-step explanation:
Number of miles driven in 45 minutes = 48 miles
We need to find how many miles will the truck drive drive in one hour. Since the rate is the same, the distance covered in each minute remains the same.
Number of miles driven in 1 minute = miles
Since, 1 hour = 60 minutes, we can write:
The number of miles driven in 1 hour (60 minutes) = miles
This means the truck driver can drive 64 miles in an hour.

0.05x+0.02(2000-x)=77.5
0.05x+40-0.02x=77.5
(0.05-0.02)x=77.5-40
0.03x=37.5
X=37.5/0.03=1250 at 2%
2000-1250=750 at 5%
Factor out the 4 in both equations
8a^2-20^2=(2^2 times a^2 times 2)-(2^2 times 5)
therefor it is also equal to
(2a)^2 times 2-(2^2 times 5)
we can force it into a difference of 2 perfect squares which is a^2-b^2=(a-b)(a+b)
(2a√2)^2-(2√5)^2=((2a√2)-(2√5))((2a√2)+(2√5))
Answer:
Step-by-step explanation:
9.)
z + 3 > 2/3
z > -7/3
You want an unshaded dot on the point -7/3 going towards the right.
10.)
1/2 ≤ c - 3/4
5/4 ≤ c
You want a shaded dot on the point 5/4 going towards the left.
