What is the approximate length of the base of the parallelogram in the diagram?
Answers
Answer:
2piR
Step-by-step explanation:
The base of the parallelogram is equal to the circumference.
The length of the base of the parallelogram will be πr.
What is Parallelogram? What is triangle? What is a expression? What is a mathematical equation?In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically - ∠x + ∠y + ∠z = 180°There are different types of triangles such as - equilateral triangle , scalene triangle , isosceles triangle etc.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions.We have a circle converted into a parallelogram as shown.
The angle subtended by each arc at the center =
Ф = (360°/8) = 45°
Length of each arc will be -
L = (Ф/360°) x 2πr
L = (45/360) x 2πr
L = (5/40) x 2πr
L = 1/8 x 2πr
L(A) = πr/4
Length of the base will be -
L(B) = 4 x L(A) = 4 x πr/4 = πr
Therefore, the length of the base of the parallelogram will be πr.

Keisha is babysitting at $8 per hour to earn money for a car. So far she has saved $1300. The car that Keisha wants to buy costs at least $5440. Write and solve an inequality to determine the amount Keisha still needs to earn for the car.
Answers
Answer:
$4100
Step-by-step explanation:
For Kaisha to get this car we have these information available
Amount saved = $1300
The cost of the car = $5400
Let The amount left to complete the car = k
We have this equation
K + $1300 = $5400
K = 5400 - 1300
K = 4100
Therefore Kaisha still needs to earn an additional amount of $4100 for the total amount of the car to be completed.

Assume that a simple random sample has been selected and test the given claim.Claim: The average age of actresses when they win an acting award is more than 34 years oldTo test this claim a simple random sample (SRS) of 27 actresses is used. This sample of 27 actresses had a sample mean of 31.4 years and a standard deviation = 11.2 years. Assume the the distribution of actresses ages is approximately normal.Select all TRUE statements from those given below..For this hypothesis test; H0: ? 34 H1: ?>342. The correct decision is to "support" (fail to reject) the null hypothesis H0.3. We decide to reject the claim that the average age of actresses when they win an acting award is more than 34 years old.4. For this hypothesis test, the P-value = .8815. For this hypothesis test, the test statistic is t = -1.21

a profit of 24% was made wheb a book was sold for birr 34% find the selling price that would have given a profit 28%
Answers
Answer:
$35.20
Step-by-step explanation:
Given that the profit of 24% was made on $34.10,
And Profit = Selling price - cost price,
Where profit is 24%, and selling price is $34.10, cost price = ?
Then, to find the cost price (z):
Assume the cost price be a 100% and the selling price of $34.10 be 124%
Hence, we have
$34.10 = 124%
z = 100%
Substitue
=> z / 34.10 = 100% / 124 %
=> 124z = 34.10 (100)
124z = 3410
Divide both sides by the coefficient of z which is 124
z = $27.50
Therefore, to find the selling price for a profit of 28%
We have 28% of 27.5 = 7.70
With equation of Profit = Selling price - cost price
We have 7.70 = Selling price - 27.50
Removing 7.7 from both sides
We have, Selling price = 27.50 + 7.70
=> Selling price = $35.20
Hence, the selling prices for a profit of 28% is $35.20

a) Find the ratio women : men.
Give your answer in its simplest form.
women : men
Answers
Answer:
13:7
Step-by-step explanation:
We see that the ratio from women:children is 13:4.
Therefore, the number of women is 13.
In the ratio comparing men to children we see that it is 7:3.
Therefore, the number of men is 7.
Now we need to compare the number of women to the number of men which is 13:7.
