What is the minimum cuts
needed to cut a circle into 8
equal parts?
What is the minimum cuts needed to cut a circle into 8 equal parts ?
A : 4 cuts
Answer:
4 cuts.Step-by-step explanation:
When we have a circle, each cut (supposing the curst are in the exact middle) which give use two haves. So, if we cut one time, we'll have two equal parts, if we cut a second time, we'll have 4 equal parts, a third time, we'll get us 6 equal parts, and if we cut a fourth time, we'll have 8 equal parts.
So, whenever we have this kind of problem dividing circles, we just say that each cut in the exact middle equals two equal haves, so if we have 4 cuts, we just multiply them by 2, 4(2)=8. Therefore, we have 8 equal parts.

The graph shows the relationship between time and the number of soda bottles a machine can make. Use the points (4,80) and (7,140) to find the number of soda bottles the machine can make each minute.
This is a mathematics problem involving the calculation of the slope of a line graph. The machine produces 20 soda bottles per minute as concluded from the given coordinates (4,80) and (7,140).
Explanation:The subject of this question falls under Mathematics, specifically the topic of linear relationships or functions. The task is to calculate the rate at which soda bottles are made per minute using the given coordinates of the graph, (4,80) and (7,140).
First, we need to calculate the slope of the line represented by these points since the slope corresponds to the number of soda bottles produced per minute. In a linear relationship, the slope of the line can be found using the formula: slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.
In this case, (x1, y1) is (4,80) and (x2, y2) is (7,140). Plugging these values into the slope formula, we get: slope = (140 - 80) / (7 - 4) = 60 / 3 = 20.
So, the machine produces 20 soda bottles per minute.

A long-distance telephone company charges a rate of 8 cents per minute or a 50-cent minimum charge per completed call, whichever is greater. Find the cost, in cents per minute, for a 3-minute call.
Answer:
Cost of a 3 minute call is 50 cents at a rate of 16.67 cents per minute.
Step-by-step explanation:
We are given the following in the question:
Plan A
A rate of 8 cents per minute.
Plan B
A 50-cent minimum charge per completed call.
We have to find the cost, in cents per minute, for a 3-minute call.
Cost according to plan A:
[tex]\text{Cost per minute}\times \text{Call length in minutes}\\= 8 \times 3\\=24 \text{cents}[/tex]
Cost according to plan B:
50 cents for a 3 minute call
Rate =
[tex]\displaystyle\frac{\text{Total cost}}{\text{Duration of call}} = \frac{50}{3} = 16.67 \text{ cents per minute}[/tex]
The company chooses the plan with greater cost, thus, it chooses plan B.
Thus, cost of a 3 minute call is 50 cents at a rate of 16.67 cents per minute.

Nathan estimated 67*36 by finding 70*40. Nathan’s estimate be greater than or less than the actual product? Explain.
Answer:
Nathan's estimate would be greater than the actual product.
Step-by-step explanation:
Let a, b, c, d be natural numbers such that a<c and b<d
Multiplying a positive number on both sides doesn't affect the inequality
⇒a×b < c×b and c×b < c×d
⇒a×b < c×d
Here 67<70 and 36<40
∴67×36<70×40
Hence, Nathan's estimate would be greater than the actual product.

A jacket that originally cost 20 is on sale for 75% off what is the sale price of the jacket? What was the amount of the discount?
Thus, a product that normally costs $20 with a 75 percent discount will cost you $5.00, and you saved $15.00. You can also calculate how much you save by simply moving the period in 75.00 percent two spaces to the left, and then multiply the result by $20 as follows: $20 x .75 = $15.00 savings.
Answer: $35
Step-by-step explanation:

Eli took out a 20-year loan for $135,000 at 4.8% interest, compounded
monthly. If his monthly payment on the loan is $876.09, how much of his first
payment went toward note reduction?
O A. $876.09
B. $336.09
O
c. $540.00
D. $420.48
Answer:
B. $336.09
Step-by-step explanation:
Monthly payment = $876.09
Interest rate = 4.8%
Convert the annual interest rate to monthly rate = 4.8% / 12
Monthly rate = 0.4% or 0.004
Amount going towards interest payment = 0.004* loan amount
Interest = 0.004 * 135,000
Interest = $540
Therefore, from the monthly payment of $876.09 , $540 goes towards paying interest and the balance is the note reduction;
Note reduction = $876.09 - $540 = $336.09

336.09

There are 12 pupils in a class.
They are each asked whether they have a brother or a sister.
9 say they have a brother.
7 say they have a sister.
2 say they have neither.
Fill in the Venn diagram.
Answer:
The value in box of circle B is 3 and the value in box which belongs in both circle B and S is 6 and value which belongs in circle S is 1 and the value of box outside both the circle is 2.
Step-by-step explanation:
In given Venn diagram
ε = class of 12 pupils
pupils who have brother B = 9
pupils who have sister S = 7
pupils who have neither brother nor sister = 2
Hence the Venn diagram is drawn in the attachment for your reference.
n(E) =12
n(neither B nor S) = 2
So, n(B or S)= n(E) - n(neither B nor S)= 12-2=10
n(B) = 9
n(S) = 7
Now, addition theorem,
n(B or S) = n(B) + n(S) - n(B and S)
[tex]10=9+7-n(B\ and \ S)\\n(B\ and \ S) = 6[/tex]
So the value in box which is in both circle B and S is 6.
So the Box which contains only brothers = n(B) - n(B and S) = 9 - 6 = 3
Value in box of circle B is 3.
So the Box which contains only Sisters = n(S) - n(B and S) = 7 - 6 = 1
Value in box of circle S is 1.
There are 12 pupils in a class so, the number of pupils having both brother and sisters are 6 and the pupils had either brother or sister are 10.
Given :
There are 12 pupils in a class.9 say they have a brother. 7 say they have a sister. 2 say they have neither.Given that there are pupils in a class that is, n(E) = 12
Pupils who have brother, n(B) = 9
Pupils who have sister, n(S) = 7
Pupils who have neither brother nor sister, n(neither B nor S) = 2
So, n(B or S) = n(E) - n(neither B nor S)
= 12 - 2 = 10
n(B or S) = 10
Now, through the addition theorem:
n(B or S) = n(B) + n(S) - n(B and S)
10 = 9 + 7 - n(B and S)
n(B and S) = 6

A scientist has two solutions which she has labeled solution A and solution B. Each contains salt. She knows that solution A is 30% salt and solution B is 55% salt. She wants to obtain 60 ounces of mixture that is 45% salt. How many ounces of each solution should she use?
Answer:
A= 24 ounces and B= 36 ounces.
Step-by-step explanation:
Given: Solution A contain 30% salt= 0.30 salt.
Solution B contain 55% salt= 0.55 salt.
New mixture should be of 60 ounces with 45% salt.
Let x be the amount of mixture for solution A. Let y be the amount of mixture of solution B.
Scientist need to to obtain 60 ounce of mixture from solution A and B.
∴ [tex]x+y= 60\ ounces[/tex]
y= [tex]60-x[/tex] equation 1
Now, solving to get final solution.
∴ [tex]0.3x+0.55y=0.45\times 60\ ounces[/tex]
Substituting the value of y from equation 1
⇒ [tex]0.3x+ 0.55\times (60-x)= 27[/tex]
⇒ [tex]0.3x+33-0.55x= 27[/tex]
⇒ [tex]-0.25x= -6[/tex]
∴ x= 24 ounces
Next, finding y
y= 60-x
∴ y= [tex]60-24= 36\ ounces.[/tex]
y= 36 ounces.
Now, we can say scientist would require 24 ounces of solution A and 36 ounces of solution B to obtain mixture of 60 ounces with 45% salt.
Kayla is buying fruit for packed lunches. She needs to buy an assortment of at least 15 apples and oranges and spend less than $20.00. Apples (x) cost $0.65 each, an oranges (y) cost $0.78 each. Which system of linear inequalities models this situation?
Final answer:
The system of linear inequalities for Kayla's fruit purchase is x + y ≥ 15 to represent the quantity of fruit, and 0.65x + 0.78y < 20 to represent the budget constraint.
Explanation:
The student's question is asking for a system of linear inequalities that would model the situation in which Kayla wants to buy at least 15 fruits consisting of apples and oranges, without spending more than $20. Given that apples (x) are $0.65 each and oranges (y) are $0.78 each, we can set up the following inequalities:
x + y ≥ 15
0.65x + 0.78y < 20
The first inequality represents the requirement that Kayla needs to buy at least 15 pieces of fruit. The second inequality represents the constraint that she needs to spend less than $20 on her purchase.

15. Which of the following equations was
used to graph the line shown?
A. y=6 + x
B. y=6 - x
C. y=x- 6
D. y=6x
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c (m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 0)
m = [tex]\frac{0-6}{6-0}[/tex] = [tex]\frac{-6}{6}[/tex] = - 1
Note the line crosses the y- axis at (0, 6 ) ⇒ c = 6
y = - x + 6 or y = 6 - x ⇒ B
