Answer:
r ≅ 10.2m
Step-by-step explanation:
Use formula: s = r * θ
s = arc length
r = radius
θ = angle in radians
8 = r * π/4
r = 32/π
r ≅ 10.2m

Step-by-step explanation:
The diagonals of a rectangle have length 12 and intersect in a 40 degree angle. Find the length and width rounded to the nearest tenth.
Answer:
Length is 7.7 and width is 9.2
Step-by-step explanation:
The length and width of the rectangle will be the y and x coordinate of the diagonal line at angle of 40 degrees
Length L = dsin theta
Width W = d coos theta
d is the length of the diagonal
Given
d = 12
theta = 40°
Substitute
Length = 12sin40°
Length = 12(0.6428)
Length = 7.7135
Length ≈ 7.7
Width = 12cos 40
Width = 12(0.7660)
Width = 9.192
Width = 9.2
Hence the length is 7.7 and width is 9.2
Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana's account can be
represented by the equation y = 25x + 125, where x is the number of weeks she has been mowing the lawn. What does the y-intercept of the graph
represent in this situation?
Hi there! x would be 6 weeks..
Explanation:
So here says that Jana earns $25 per week for mowing the lawn. But in “x” weeks, she earns $125...this means that you would have to divide 125 with 25 or 25 multiply by x to find the answer of x.
How much does 25 go to 100? Well it would be 5. So for $100 it would be 5 weeks. We also know that 25 is 1 week. So add 5 with 1. 5 plus 1 would be 6.
Therefore, for $125, Jana would have to work for 6 whole weeks.

Mrs.Browns rectangular kitchen is 10 ft wide and.16 ft long, if she creates a scale drawing.With a length of 4 inches, what would be the width
Answer:
2.5 inches
Step-by-step explanation:
1 feet = 12 inches
The length is 16 ft x 12 = 192 inches
The length was scales by an unknown measure which i would represent with x . The equation is as follows
192 inches x a = 4 feet
a = 48
The kitchen was scaled by 48
10 x 12 = 120 inches
120/48 = 2.5 inches
-8+2n+10+5n simply the expression .
Find X Give your answer in simplest form
Given:
A figure of a right angle triangle.
To find:
The value of x.
Solution:
In a right angle triangle,
[tex]\tan \theta = \dfrac{Opposite}{Adjacent}[/tex]
In the given triangle,
[tex]\tan (30^\circ) = \dfrac{x}{7}[/tex]
[tex]\dfrac{1}{\sqrt{3}}=\dfrac{x}{7}[/tex]
On multiplying both sides by 7, we get
[tex]\dfrac{7}{\sqrt{3}}=x[/tex]
Therefore, the value of x is [tex]x=\dfrac{7}{\sqrt{3}}[/tex].

Answer:
11 1 /2 ( 11 and a half)
Step-by-step explanation:
If you noticed 7 and 2 are five numbers away.
To solve this I just added one to both of them until the sum was equal to 28.
If I had added one to 16 and 11, it would have given me 29, so I added a half.
That gave me 28.

The function P(1) - 5,000(1.098)' models the value, in dollars, of a painting after t years. What is the initial value of the painting?
Answer:
the answer is $5,000
Step-by-step explanation:
the question is asking what the initial value of the painting is and in the equation, they are trying to find out how much the painting will cost after t years. the 1.098 is how much the painting decreases each year and it is being multiplied by &5000 so $5000 is the original value of the painting.

Rochelle is competing in a marathon. She knows that once she runs 14.7 km she will have completed 35% of the marathon
Given :
Rochelle is competing in a marathon.
She knows that once she runs 14.7 km she will have completed 35% of the marathon.
To Find :
Total length of the marathon.
Solution :
Let, total distance of the marathon is x km.
So, 35% of x is 14.7 .
In mathematics :
[tex]14.7 = x\times \dfrac{35}{100}\\\\x = \dfrac{14.7\times 100}{35}\\\\x = 42\ km[/tex]
Therefore, total length of the marathon is 42 km.

If the price of a sweater was $37.38 after a 35% discount, what was the original price? Round your answer to the nearest cent.
Answer:
$57.51
Step-by-step explanation:
If the price of a sweater was $37.38 after a 35% discount, what was the original price? Round your answer to the nearest cent.
The formula for the original price =
= Sales price/1 - Percentage discount
Percentage discount = 35% = 0.35
Original price = $37.38/1 - 0.35
= $37.38/0.65
= $57.507692308
Approximately = $57.51
Therefore, the original price H= $57.51
