Solution:
<u>Note that:</u>
- Circumference = 50.24 ft = 2πr = πd
- Dia. = 16 ft.
<u>Divide the diameter both sides.</u>
- 50.24 ft = πd
- => 50.24/d ft = πd/d
- => 50.24/d ft = π
<u>Substitute the diameter in the equation.</u>
- => 50.24/16 = π (Option A)
The two friends will be 150 miles apart, when the sum of the distances covered by the them is 150 miles.
distance = speed x time.
Let the time covered when they are 150 miles apart be x, then:
40x + 35x = 150
75x = 150
x = 150/75 = 2.
Therefore, the two friends will be 150 miles apart in 2 hours.
Answer:
Step-by-step explanation:
y = -x + 1......same as y = -1x + 1.....in y = mx + b form, ur slope is in the m position....so the slope of this line is -1.
a parallel line will have the same slope.
(-1,3)...x = -1 and y = 3
slope(m) = -1
y = mx + b.....we have x,y, and m....now we need to find y int (b)
3 = -1(-1) + b
3 = 1 + b
3 - 1 = b
2 = b
so ur parallel equation is : y = -1x + 2...or just y = -x + 2
