Answer:
80 ft (b)
Hope it helps
Step-by-step explanation:
Circumference= π * diameter
Since the circumference is given..
250 = πd
d = 250/π
= 250/3.14
= 79.6
= 80 feet approx
You have to set up 2 proportions.
If the 6.9 goes with the 5 then the proportion will look like this.
6.9/5 = x/6 Cross multiply
6 * 6.9 = 5x
41.4 / 5 = x
x = 8.28 or 8.3
If on the other hand the 6.9 goes with the 6 then the second proportion is
6.9/6 = x/5
6.9 * 5 = 6X
34.5 / 6 = x
x = 5.75
Answer: D <<<<<<<<======
Answer:
Step-by-step explanation:
x = larger number, y = smaller number
x + y = 57
x = 2y - 3
2y - 3 + y = 57
3y - 3 = 57
3y = 57 + 3
3y = 60
y = 60/3
y = 20 <=== the smaller number
x = 2y - 3
x = 2(20) - 3
x = 40 - 3
x = 37 <=== the larger number
<span>Distance = d miles ; rate = 60 mph ; time = d/60 hrs
distance = d miles ; rate = 50 mph ; time = d/50 hrs
----------------------
Round-trip DATA:
distance = 2d miles ; rate = 55 mph ; time = (2d)/55 hrs
-----------------------------------------------------------
Equation:
Roundtrip time - other time = -1/2 hr
(2d)/55 - [(d/60)+(d/50)] = -1/2
(2d)/55 - [(110d)/(50*60)] = -1/2
---
600(2d) - 11[110d] = -16500
1200d - 1210d = -16500
-10d = -16500
distance = 1650 miles

Hey there, 125/5=25 and 25*5=125, Therefore, ∛125=5
