Find the central angle using a ratio in regards to angle and circumference.
The radius is 27 units, so use the following equation to calculate circumference:
C = 2rπ
Therefore:
C = 2(27)π = 54π
Since we have the total circumference, we can write the following proportion:
[tex]\frac{x}{360} = \frac{18\pi}{54\pi}[/tex]
Cross multiply:
54πx = 6480π
Divide both sides by 54π to isolate for x:
x = 120°

Answer:15
Step-by-step explanation:
Answer:
The answer is B) 75
Step-by-step explanation:
The angle shown is a 90-degree angle. Therefore if the other angle is 15 degrees, that means that all we have to do is subtract 15 from 90.
90-15= 75 which means the angle known as x is a 75-degree angle.

1) 4k = 24
2) 34 + h = 60
3) 1/5x = 30
4) m-42 = 85
Answers
Isolate the variable, note the equal sign, what you do to one side, you do to the other.
1) 4k = 24
Isolate the variable, k. Divide 4 from both sides of the equation:
(4k)/4 = (24)/4
k = 24/4
k = 6
2) 34 + h = 60
Isolate the variable, h. Subtract 34 from both sides of the equation:
34 (-34) + h = 60 (-34)
h = 60 - 34
h = 26
3) 1/5x = 30
Isolate the variable, x. Multiply 5 to both sides of the equation:
(5) * (1/5)x = (30) * (5)
x = 30 * 5
x = 150
4) m - 42 = 85
Isolate the variable, m. Add 42 to both sides of the equation:
m- 42 (+42) = 85 (+42)
m = 85 + 42
m = 127

Answers
Answer:
1) 5% of 90m= 4.5m
2)25% of 88kg = 22kg
3) 75% of 264= 198
Step-by-step explanation:
1) 90m = 100% (divide by 10)
9 = 10% (divide by 2)
4.5 = 5%
2) 88kg = 100% (keep on dividing by 2)
44kg = 50%
22kg=25%
3) 264 = 100%
132 = 50%
66 = 25% (add)
198=75%

Your restaurant bill comes to $46.27. Estimate a 10% tip.
Answers
If the bill of the restaurant comes to $46.27 then the tip of 10% is equal to $4.627.
What is percentage?Percentage is number or ratio that is expressed as a fraction of 100. It is shown by % sign. It shows some quantity over other quantity. The number which shows the percentage is the number in the quantity itself.
How to calculate percentage?We have been given that the bill of the restaurant comes to $46.27 and 10% is the tip. We have to calculate the tip.
Tip=Bill*10/100
=46.27*10/100
=4627*10/100*100
=46270/10000
=$4.627
Hence if the bill of the restaurant is $46.27 then tip will be $4.627.

The graph shows the relationship between the distance a car is driven and the number of gallons of gasoline used. Identify the value in d in the point (1, d). What does that point represent?
A. d=25; the unit rate is 25 miles per gallon
B. d=25; the unit rate is 25 gallons per mile
C. d=50; the unit rate is 50 miles per gallon
D. d=50; the unit rate is 50 gallons per mile
Answers
Answer:
A. d = 25; the unit rate is 25 miles per gallon
Step-by-step explanation:
The point (1, d) on the graph represents (x, y), where,
x = gasoline used = 1 gallon
y = distance = d = 25 miles
That is, (1, d) represents when x = 1, y = 25.
Thus, (1, 25) is the unit rate which is 25miles per gallon.

The number that has 1/10th the value of 0.3 is 0.03.
Each place value to the left of a decimal place is 10x the value of the one closer to the decimal, and each place value to the right of a decimal is 1/10th the value of the place closer.
Answer: D) 2.33 meters
==========================================================
Explanation:
The hundredths digit is 1/10 of the tenths digit. Because of this, the tenths and hundredths digit must be the same digit.
Only choice D fits the description.
The digit in the tenths place represents the value 0.3
Taking 1/10th of this leads to (1/10)*0.3 = 0.1*0.3 = 0.03
So the hundredths place represents the value 0.03
Note that,
2 + 0.3 + 0.03 = 2.33 meters
