Answer:
The length of the circular arc is 8.64 inches
Step-by-step explanation:
Length of circular arc (L) = central angle/360° × 2πr
central angle = pie/4 = 45°, r (radius) = 11 inches
L = 45°/360° × 2 × 3.142 × 11 = 8.64 inches (to two decimal places)
20 imperial gallons = 90.9218 litres
so i'd say you'd need to buy 91 bottles or...
20 US Liquid gallons = 75.7082 litres
so you'd have to buy 76 bottles.
Hope this answers your question! It depends what gallon you're working from.
Refer to below for answer:
Ok, so they are all balanced, so each side of the scale thing is equal to the other side.
A. 3 + x = 8
If we subtract 3 from 8, what’s left is 5 for x
x = 5
B. 2y = 12
Both y weights are equal, so dividing 12 by 2 says each y weight is 6.
y = 6
C. 4z = 11
All z weights are equal, so divide 11 by 4 to find the weight of z
z = 2.75
D. 3 4/5 + w = 13 4/5
Subtract 3 4/5 from 13 4/5 to find the weight of w
w = 10
Let me know if you have questions about this.
Answer:
The distance from Simon's house to the beach is 137.5 miles
Step-by-step explanation:
we know that
The speed is equal to the ratio of the distance and the time
Let
s ----> the speed in mph
x ----> the distance in miles
y ---> the time in hours

we have


substitute in the formula and solve for x
