Answer:
a, b, e (only)
Step-by-step explanation:
The circle centered at A is all of the points that are distance AB from A.
The circle centered at B is all of the points that are distance AB from B.
The points C and D are points that are distance AB from both A and B.
The line joining those points (C and D) consists entirely of points that are equal distances from A and from B. CD is the perpendicular bisector of AB.
Point M is one of the points on line CD, and is also on segment AB. Because it is on CD, we know it is the same distance from A as from B. That means AM = BM, and M is the midpoint of AB.
__
Points B, C, D are not on the same line, so can form a triangle. As with any triangle, the sum of any two segments is greater than the length of the third. Here, this is expressed as CB + BD > CD.
__
With some work using the Pythagorean theorem, you can show that ...
CM = AM×√3
Similarly, MD = BM×√3.
Adding these two relations tells us ...
CM +MD = √3(AM +BM)
CD = AB×√3 . . . . . AB and CD are not the same length
__
AM and BM are on the same line, so cannot be perpendicular to each other.

When you are studying compass and straightedge constructions, you would do well to actually perform these constructions using those tools on paper. This gives you a feel for what is going on and helps you remember the steps. A computer screen is no substitute for hands-on.

You have the side lengths of the two legs, n and n.
Then, using the pythagorean theorem you have to find the length of the third side:
[tex]a^2 + b^2 = c^2\\n^2 + n^2 = c^2\\2n^2 = c ^ 2\\\sqrt{2n^2} = c[/tex]
where c is the third side

A rotating lawn sprinkler sprays water in a circular area of grass, as shown in the picture. The diameter of the circular area of grass is 16 ft.
Answer: G) 50.24
Step-by-step explanation: you have to find the circumference of the circle. Since you already have the diameter which is 16 all you have to do is multiply that by 3.14. If you only had the radius then you will have to multiple the radius times 2 times 3.14. The formulas for circumference are: pi(3.14) x diameter or pi(3.14) x radius x 2
Jenny bought scrapbooking supplies for $145.00. She paid $11.60 in sales tax. What was the sales tax rate on the supplies? If necessary, round your answer to the nearest tenth.
a) 7%
b) 8%
c) 9%
d) 7.5%
The sales tax rate is 8%.
The correct option is (b).
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Jenny bought scrapbooking supplies for $145.00.
She paid $11.60 in sales tax.
let the tax rate be x%.
So, the price without sales tax = 145 - 11.6 = $133.4
Thus, x% of 133.4 = 11.6
133.4 x = 1160
x = 8.65%
x= 8%
Hence, the tax rate is 8%.

Student Council held a bake sale to raise money for the local food pantry. They sold a total of 40 items which included pies and cakes. Pies were $10 each and cakes were $8 each. They raised $356. How many pies and how many cakes did they sell?
Answer: 18 pies, 22 cakes
Step-by-step explanation:
Let the number of pies sold be represented by p.
Let the number of cakes be represented by c.
The information in the question can then be represented in an equation as:
p + c = 40 ........ i
10p + 8c = 356 ....... ii
Multiply equation i by 10
Multiply equation ii by 1
10p + 10c = 400 ....... iii
10p + 8c = 356 ....... iv
Subtract iv from iii
2c = 44
c = 44/2
c = 22
22 cakes were sold
Since 40 items were sold, the number of pies sold will be:
= 40 - 22
= 18 pies

The perimeter of a rectangular pool is 72 meters. If the length of the pool is twice its breadth. Its length is_________.
Answer:
Length = 18 meters
Step-by-step explanation:
Let the length of the rectangular pool = l meters
And breadth of the pool = w meters
Perimeter of the rectangular pool = 2(l + 2w)
Since, perimeter of the rectangular pool is 72 meters.
2(l + 2w) = 72
l + 2w = 36 --------(1)
If length of the pool is twice of its breadth,
l = 2w
w = [tex]\frac{l}{2}[/tex] -------(2)
By substituting the value of 'w' from equation (2) to equation (1),
[tex]l+2\times{\frac{l}{2}}=36[/tex]
2l = 36
l = 18 meters

6x - 4 = 2x -1
4x = 3
x= 3/4
Answer:
x=3/4
Step-by-step explanation:
Remove parentheses.
3x-2=\frac{2x-1}{2}3x−2=22x−1
Multiply both sides by 22.
6x-4=2x-16x−4=2x−1
Add 44 to both sides.
6x=2x-1+46x=2x−1+4
Simplify 2x-1+42x−1+4 to 2x+32x+3.
6x=2x+36x=2x+3
Subtract 2x2x from both sides.
6x-2x=36x−2x=3
Simplify 6x-2x6x−2x to 4x4x.
4x=34x=3
Divide both sides by 44.
x=\frac{3}{4}x=43
