Answer:
a) The radius of the wheel is 1) more than 25.0 cm.
b) The radius of the wheel is approximately 40.925556... cm
Step-by-step explanation:
S = rθ is the formula to find the radius of the wheel using the arc and the angle discovered, S being the arc and θ the angle. The angle, however, must be in radians. θ = 
is used to convert it. So:
θ =
θ = 
S = rθ
25 = r
900 = 7
r
r = 
r = 40.925556... cm
Answer:
The dimensions of swimming pool are:
Length = 26.2 feet
Width = 16.3 feet
Height = 5 feet
During a few hot weeks during the summer, some water evaporates from the pool, and Jill needs to add 8 inches of water to the depth of the pool.
We will convert 8 inches o feet.
1 inch = 1/12 feet
So, 8 inch = 
feet
Now we have to tell how much water will be there in 0.66 feet depth.
So, volume = 
cubic feet.
1 cubic feet has 7.480 gallons
So, 281.86 cubic feet will have 
gallons of water.
Answer:
$61.18
Step-by-step explanation:
The price last week was an unknown. We will call it x. x is an entire amount, so it is 100% of x.
This week, the price is 15% lower. Since 100% - 15% = 85%, the price this week is 85% of what it was last week. Last week it was x, so this week, the price is 85% of x.
85% of x = $52
0.85x = $52
Divide both sides by 0.85:
0.85x/0.85 = $52/0.85
x = $61.1764...
Answer: $61.18
Answer:
643
Step-by-step explanation:
Answer:
100 texts
Step-by-step explanation:
Let the amount of text messages be x. Since we are looking at making both plans equal, we add the fixed monthly charges to the number of messages multiplied by the cost.
The total amount charged by Totally will be 30 + 0.2x
The total amount charged by Gnarly will be
40 + 0.1x
Now since we are trying to get the number of text messages that make both charges equal, we equate the two charges and that is:
30 + 0.2x = 40 + 0.1x
40 - 30 = 0.2x - 0.1x
0.1x = 10
x = 10/0.1 = 100 texts
