find the area and circumference of a circle with a radius of 5 cm use the value 3.14 do not round your answer
Answer:
area= 78.5 cm²
circumference= 31.4 cm
Step-by-step explanation:
[tex]\boxed{Area \: of \: circle= πr²}[/tex]
Given that the radius is 5cm, r= 5. Substitute r= 5 and π as 3.14 into the equation:
Area of circle
= 3.14(5²)
= 78.5 cm²
[tex]\boxed{circumference \: of \: circle =2πr }[/tex]

What is the approximate area of the shaded region? Use 3.14 for 4 in 5 in KONA. 19 square inches A. O B. 23.14 square inches ( C. 16.86 square inches 0 D. 18.43 square inches
Answer:
16.86 in²
Step-by-step explanation:
Area of rectangle = 5 * 4 = 20 in²
Area of circle = π(1)² = 3.14 in²
So the area of shaded region = 20 - 3.14 = 16.86 in²

The model for long-term average temperature f (x), in degrees Celsius, at the Willburn airport is represented by the equation f of x is equal to 5 times sine of the quantity x over 12 end quantity plus 14 and 5 tenths period If x represents the month of the year, in which months will the temperature be 17°C?
x equals pi over 6 plus 2 times pi times n and x equals 5 times pi over 6 plus 2 times pi times n
x equals pi over 6 plus 24 times pi times n and x equals 5 times pi over 6 plus 24 times pi times n
x = 2π + 2πn and x = 10π + 2πn
x = 2π + 24πn and x = 10π + 24πn
Answer:
need more info
Step-by-step explanation:
what are we sloving
The expression that represents the month of the year, in which months will the temperature be 17°C is x = 2π
How to determine the month of the year?The function is given as:
f(x) = 5sin(x/12) + 14.5
When the temperature is 17°C, the equation becomes
5sin(x/12) + 14.5 = 17
Subtract 14.5 from both sides
5sin(x/12) = 2.5
Divide both sides by 5
sin(x/12) = 0.5
Take the arc sin of both sides
x/12 = π/6
Multiply both sides by 12
x = 2π
Hence, the expression that represents the month of the year, in which months will the temperature be 17°C is x = 2π

Given :-A boy wishes to divide a board of 20 cm long into 3 pieces He divided the board in the ratio of 1 : 2 :4 To Find :- We have to find the length of each divided piece of board Let's Begin :-Let the given ratios be 1x, 2x and 4x
The total length of the board is 28 cmHe divided it in ratio 1 : 2 : 4 Therefore,According to the question,
[tex]\sf{ x + 2x + 4x = 28}[/tex]
[tex]\sf{ 7x = 28}[/tex]
[tex]\sf{ x = }{\sf{\dfrac{28}{7}}}[/tex]
[tex]\sf{ x = }{\sf{\cancel{\dfrac{28}{7}}}}[/tex]
[tex]\bold{ x = 4}[/tex]
Thus, The value of x is 4
Now,Length of first piece = 4 cm
Length of second piece
[tex]\sf{ = 2}{\sf{\times{4}}}[/tex]
[tex]\bold{ = 8\: cm }[/tex]
Length of third piece
[tex]\sf{ = 4}{\sf{\times{4}}}[/tex]

a water tank holds 208 gallons but is leaking at a rate of 3 gallons per week. a second water tank holds 312 gallons but is leaking at a rate of 5 gallons per week. after how many weeks will the amount of water in the two tanks be the same?
Answer:
x = 64 weeks
Step-by-step explanation:
Based on the quantity of water in the tanks and the leakage rate, the two tanks will be equal after 64 weeks.
The first tank has 256 gallons and is leaking at 3 gallons per week. Assuming the number of weeks is x, the expression is:
= Water in tank - (Gallons leaking per week x No. of weeks)
= 256 - (3 × x)
= 256 - 3x
The second tank:
= 384 - 5x
To find the number of weeks they would be equal, equate both tanks:
384 - 5x = 256 - 3x
384 - 256 = -3x + 5x
128 = 2x
x = 128 / 2

where a is the starting amount, r is the rate in decimal format, and x is the number of years
Given:
Starting amount = $600Annual return = 5% = 0.05[tex]\implies g(x) = 600 \cdot 1.05^x[/tex]

Compare:
X and X decreased by 50% and then increased by 50% of the result
Step-by-step explanation:
100% = X
50% = 100%/2 = X/2
X decreased by 50 means X - 50% = X - X/2 = X/2
now,
100% = X/2
50% = 100%/2 = X/2 / 2 = X/(2×2) = X/4
increasing the previous result by 50% means
X/2 + 50% = X/2 + X/4 = 2X/4 + X/4 = 3X/4
so, comparing this to the original X (= 4X/4), we are X/4 short.

10
46
74
99
Answer:
74°
Step-by-step explanation:
m(arc)JKL = 2 × 99° = 198°
8x - 6 + 12x + 4 = 198
20x - 2 = 198
20x = 200
x = 10
m(arc)KJ = 8x - 6 = 8(10) - 6 = 74°

Will a fraction increase or decrease and by what percent if its numerator is increased by 20% and its denominator is increased by 50%? The fraction will increas...
Answer:
decrease of 80%
Step-by-step explanation:
See image.
Use variables for the fraction.
Numerator means the top number.
Denominator means the bottom number.
Change percents to decimals to calculate.
.8 is 80%.
80% will make the whole fraction smaller.
see image
Answer:
The fraction will decrease by 20%.
You can suppose other fractions too you will get the same answer though.
Step-by-step explanation:
Let the fraction be 1/2
Now,
1/2
=> 1 + 20% of 1 => 1 + 20/100 => 6/5
=> 2 + 50% of 2 => 2 + 1/2 * 2 => 2 + 1 => 3
so,
6/5/3 => 2/5
Now,
1/2 - 2/5 => 1/10
Now,
1/10/1/2 * 100%
= 1/5 * 100%
= 20%
