Write the equation for the perpendicular bisector of a segment that has endpoints (–1, 10) and (3, 6).
A) y = x – 7
B) y = x + 7
C) y = –x + 9
D) y = x + 11
Answer:
y= x+7
Step-by-step explanation:
find the midpoint using the midpoint formula
you get (1,8)
find the slope
-1 and the opposite reciprocal is 1
put the midpoint and the opposite reciprocal slope in
the formula y-8= 1(x-1)
simplify y=x+7
Suppose Huston deposit $600 into a savings account with a simple interest rate of 2.5%. How many years would he have to keep his money in the bank in order to earn at least $120 in interest?
Answer:
At least 8 yearsStep-by-step explanation:
Deposit = $600
Interest rate = 2.5% simple
Time = x years
Target interest amount ≥ $120
600*0.025*x ≥ 12015x ≥ 120x ≥ 120/15x ≥ 8 yearsAt least 8 years
These two images show steps in a proof of the Pythagorean theorem. Which
of the following statements about the proof is false?
A. The triangles in step 1 have the same combined area as the triangles in step 2.
B. The area of the interior square in step two is greater than the combined area of the two interior squares in step 1.
C. The proof shows that a2+ B2=C2
D. If you subtract the sum of the areas of the four triangles from the complete figure in both steps, the remaining areas are equal.
Answer: B, the area of interior square in step 2 is greater than the combined area of the two interior squares in step 1.
Step-by-step explanation: I took the quiz and got it right
The area of the interior square in step 2 is greater than the combined area of the two interior squares in step 1. Then the correct option is B.

7(3 + 4y) - 15y = 73
( Multi-step equations)
show work please and thank you
Answer:
Step-by-step explanation:
7(3+4y)-15y=73
21 plus 28y-15y=73
21 plus 13y = 73
13y=51
y=4
Step-by-step explanation:
Step 1: Multiply the 7 into the bracket.(make sure that your signs are correct)
Step 2: Minus the 21 from the 73.( Because when you take a value over the equal sign the value's sign changes)
Step 3: Minus 15y from 28y.
Step 4: Divide 52 by 13( because when you take the 13 over it divides ,because on the other side lf the equal the 13 multiples with the y)
A glacier travels 10 kilometers in 20 years, what is its speed?
Answer:
To change from meters per day into kilometers per year, you just have to change from meters to kilometers and from days to years. You just multiply/divide by the unit conversions (for example, 1000 meters per kilometer) in a way that cancels out the units and leaves just kilometers and years:

Hi, I am confused on this question:
The sequence 12, 15, 18, 21, 51, 81, ... consists of all positive multiples of 3 that contain at least one digit that is a 1. What is the 50th term of the sequence?
(Source: 2006 National Target #5)
Answer:
321.
Step-by-step explanation:
The next term after 81 is 102 .
Between 102 and 198 inclusive we have (198-102) / 5 + 1 = 96/3 + 1 = 33 terms - these will all have at least one 1 and be divisible by 3.
So 198 = 6 + 33 = 39th term.
After 198 we have 201, 210, 213, 219, 231, 261, 291, 312, 315, 318, 321
The answer is 321..

A'Reana earns a weekly allowance for doing chores around the house and for keeping all of her grades above a C. During a particular week, she gave
$10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50. How much is
A'Reana's weekly allowance?
Answer:
Answer: A'Reana's weekly allowance is $100
Step-by-step explanation:
Backward Solution
To solve some problems, we can work backward, using the inverse operations, to arrive at the solution.
The problem explains a sequence of expenses A'Reana does with her weekly allowance. In the end, she had $37.50.
That final balance came when she last spent $7.50 on a pizza. Thus, before that, she had $37.50+$7.50=$45
This balance is half of her previously remaining money. The other half was spent on a new shirt. Thus she had 2*$45=$90.
Those $90 were left after she gave $10 to her friend Taylor, thus, the initial money was $90+$10 = $100
Answer: A'Reana's weekly allowance is $100

Bridget goes to the mall and buys a shirt for $15.50, a pair of jeans for $32.00, and a belt for $24.30. She has a coupon and ends up getting $14.36 off her purchase. What percent off was her coupon for?
Answer:
20%
Step-by-step explanation:
Cost of Shirt = $15.50
Cost for a pair of jeans = $32.00
Cost for a belt = $24.30
Total cost = $15.50 + $32.00 + $24.30 = $ 71.8
Given that, coupon discount = $14.36
To find:
The percentage off on the coupon.
Solution:
The percentage off will be calculated on the total cost.
[tex]\text{Percentage\ off} = \dfrac{Coupon\ discount}{Total\ Cost}\times 100\\\Rightarrow \text{Percentage\ off}= \dfrac{14.36}{71.8}\times 100\\\Rightarrow \text{Percentage\ off} = 0.2\times 100\\\Rightarrow \text{Percentage\ off} = \bold{20\%}[/tex]
Therefore, the answer is:
20%

If I were to simplify the expression 10-19 would my answer be a positive or a negative an why
Answer:
It would be negative. 10 subtracted by any number higher then 10 will always be negative. Make a number line and go backwards 19 if you need the help.
Step-by-step explanation:
Answer: It will be negative because 19 is greater than 10 and 19 itself is being subtracted from 10.
Step-by-step explanation:
10-19 is equal to -9.
An example is using the number line to plot the solution, you will start from 10 and move backwards 19 units because you are subtracting 19 from 10. If a bigger number is being subtracted from a smaller number, the solution will be always negative.
