Answer:
75.39 in^2
Step-by-step explanation:
circumference=2πr
30.8=2(3.14)r
30.8=6.28r
4.9=r
Now that we know the radius, we can plug it in for the area equation
area=πr^2
area=(3.14)(4.9)^2
area=(3.14)(24.01)
area=75.39 in^2

The angles are supplementary.
x + 82 + x + 36 = 180
2x + 118 = 180
2x = 62
x = 31
m<ABC = x + 82 = 31 + 82 = 113

A rectangular field is 36
meters long and 15 meters
wide How many more meters
18 it to walk on the sidewalk
rother than cutting through
the field diagonally?
Answer:
12meters
Step-by-step explanation:
Given data
Lenght = 36 meters
Width = 15 meters
The dimension of the diagonal can be gotten via Pythagoras theorem
D^2= L^2+W^2
Substitute
D^2= 36^2+ 15^2
D^2= 1296+225
D^2= 1521
D= √1521
D= 39 meters
Hence the distance while walking on the side is
=36+15
=51 meters
Hence the difference is
=51-39
=12meters

The ratio of pages read to minutes for Hang is 5:8. Select all the people who have a greater ratio of pages read to minutes than Hang.
Kira: 2 pages read every 4 minutes
Joe: 6 pages read every 9 minutes
Quon: 5 pages read every 7 minutes
Lulu: 10 pages read every 13 minutes
Lorenzo: 1 page read every 3 minutes
Answer:
Step-by-step explanation:
B, C, and D
By doing 5÷8 = .625 you know that Hang can read .625 of a page per minute.
You can do this for the rest of the people finding that Kira reads .5 page per minute which is a slower/ smaller ratio, Joe rate is .66, Quon's ratio is .71 and Lulus rate is .76, the only rate that is smaller than Hangs is Kira,s, leaving you with Joe, Quon, and Lulu to be your answer

- 12 = 6y +18-9y
Answer:
[tex] \boxed{y = 10} [/tex]
Step-by-step explanation:
-12 = 6y + 18 – 9y
[Group like terms 6y and -9y]
-12 = (6y – 9y) + 18
[Simplify the expression]
-12 = -3y + 18
[Subtract 18 from both sides, subtraction property of equality, to isolate the variable and the value]
-12 = -3y + 18
–18 –18
-30 = -3y
[Divide by -3 from both sides, division property of equality, to get the variable y by itself]
-30 = -3y
÷(-3) ÷(-3)
10 = y
[Symmetric property of equality, if b = a, then a = b]
y = 10
Why do you think sum or difference formulas will be helpful with finding the exact
ues of uncommon angles?
Answer:
The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle. The angle sum identities take two different formulas: sin(A+B) = sinAcosB + cosAsinB. cos(A+B) = cosAcosB − sinAsinB. The difference formula for cosines states that the cosine of the difference of two angles equals the product of the cosines of the angles plus the product of the sines of the angles. The sum and difference formulas can be used to find the exact values of the sine, cosine, or tangent of an angle.

Carrie will spin the arrow on the spinner four times. What is the probability that the arrow will stop on A, then B, then C, Then D?
Answer:
1 / 256
Step-by-step explanation:
Sample space Total sections of spinner = (A, B, C, D) = 4
P(spinner stops on A) = 1 /4
Second spin :
P(stops on B) = 1/4
Third spin :
P(stops on C) = 1/4
Fourth spin :
P(stops on D) = 1/4
Hence,
P(A then B then C then D)
1/4 * 1/4 * 1/4 * 1/4 = 1

What is the solution to this equation?
8(e)^2x+1=4
Answer:
A
Step-by-step explanation:
hello :
8(e)^2x+1=4
(e)^2x+1=4/8 = 1/2
so : 2x+1 = ln(1/2)
2x = ln(1/2) - 1
x = (ln(1/2) - 1)/2
The solution to the given exponential function is x = [ ln(0.5) - 1]/2
Solving exponential equationsThe standard exponential equation is expressed as y = ab^x
Given the expression
8(e)^2x+1=4
Divide both sides by 8
(e)^2x+1=4/8
(e)^2x+1 = 1/2
Take the ln of both sides
ln(e)^2x+1 ln(1/2)
2x + 1 = ln(0.5)
2x = ln(0.5) - 1
x = [ ln(0.5) - 1]/2
Hence the solution to the given exponential function is x = [ ln(0.5) - 1]/2

A landscaping company placed two orders with a nursery. The first order was for 13 bushes and 4 trees, and totaled $327.50. The second order was for 6 bushes and 2 trees, and totaled $142.96. Sam tried to use system of equation to solve the problem.
Answer:
Step-by-step explanation:
A landscaping company placed two orders with a nursery. Sam tried to use system of equation to solve the problem.
Let us represent
Cost of bushes = x
Cost of trees = y
The first order was for 13 bushes and 4 trees, and totaled $327.50.
Hence
13x + 4y = 327.5......Equation 1
The second order was for 6 bushes and 2 trees, and totaled $142.96.
Combined both Equations
13x + 4y = 327.5......Equation 1
6x + 2y = 142.96 ........ Equation 2
We solve using Elimination method
We Multiply Equation 1 by 2 and Equation 2 by 4 to Eliminate y
26x + 8y = 655 ..... Equation 3
24x + 8y = 571.84 ..... Equation 4
We substract Equation 4 from Equation 3
2x = 83.16
x = 83.16/2
x = $41.58

Answer:
26, 37, 40, 48
Step-by-step explanation:
Whole numbers between 20 and 50 will have 10s digits in the range 2–5.
When 4 is added to these numbers, we get ...
2+4 = 6
3+4 = 7
4+4 = 8
5+4 = 9
When 4 is subtracted from these numbers, we get ...
2-4 = -2
3 -4 = -1
4 -4 = 0
5 -4 = 1
__
The numbers we can make using the given 10s digits and their corresponding 1s digit(s) are ...
26, 37, 40, 48
__
We note that any number with a 10s digit of 5 and a 1s digit other than 0 will be out of range.
