Step-by-step explanation:
x=10
y=7.5
CE = 6
BD=4.5
Explanation:
Use similar triangles. Since you know one side length of the larger triangle, divide it by the hypotenuse of the smaller triangle to get the factor you are multiplying you side lengths by.
12.5 / 5
= 2.5
Multiply every other side length by 2.5
4 x 2.5 = 10
x = 10
3 x 2.5 = 7.5
y = 7.5
To get CE and BD subtract your values:
CE = 10 - 4
CE = 6
BD = 7.5 - 3
BD = 4.5

Ronnie charges his customers a flat fee of $25 to fix a computer. Then, he charges $30 for each hour he spends working on the computer. If his first job cost $175, how many hours did he spend working?
Answers
Answer:
Ronnie spent 5 hours working.
Step-by-step explanation:
From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:
c=25+30x, where:
c is the total cost of the job
x is the number of hours
Now, you can replace c with 175 and solve for x:
175=25+30x
175-25=30x
150=30x
x=150/30
x=5
According to this, the answer is that Ronnie spent 5 hours working.
Answer:
7.5
Step-by-step explanation:
Ronnie charges $25 plus $20 per hour. This means that he made the following depending on how many hours he spent on it:
Hours Dollars
0 25 = 25 + 0(20)=25
1 25+20 = 25 + 1(20)=45
2 25+20+20 = 25 +2 (20)=65
3 25+20+20+20 = 25 +3 (20)=85
4 25+20+20+20+20 = 25 +4 (20)=105
5 25+20+20+20+20+20 = 25 +5 (20)=125
......
n 25+n(20)=175
To find how many hours he worked for $175 we solve the equation using inverse operations:
25+n(20)=175
25-25+n(20)=175-25
n(20)=150
n= 7.5 hours

Bart had an income of $38,250 last year. If the inflation rate is 4.5%, what is his purchasing power?
A. $33,614.85
B. $34,543.75
C. $34,998.15
D. $36,528.75
Answers
Answer: D) $36,528.75
=======================================================
Explanation:
Positive inflation eats away at the purchasing power of money.
If inflation is 4.5%, then the purchasing power goes down by 4.5% meaning his purchasing power is 100% - 4.5% = 95.5% of what it used to be.
95.5% of $38,250 = 0.955*38250 = 36,528.75
So his purchasing power is $36,528.75
The purchasing power of Bart by the income of last year is option D. $36,528.75.
What is Inflation?Inflation can simply be defined as the increase in the rate of the prices over a period of time. In other words, inflation describes how much more expensive has a commodity or service becomes in a period of time.
It is clear that, inflation decreases the purchasing power of money.
Given that, the inflation rate is 4.5%.
Also, Bart had an income of $38,250 last year.
Purchasing power will get decreased by 4.5%.
Purchasing power = $38,250 - ($38,250 × 4.5%)
= $38,250 - (1721.25)
= $36,528.75
Hence the purchasing power of Bart is $36,528.75.

Answers
Answer:
Only A, the first equation is true.
Step-by-step explanation:
A. (y + 6)(y – 7) + 42 = y² + 6y –7y – 42 + 42 = y² – y. This means A is true
B. (x + 3)(X – 8) = x² + 3x – 8x – 24 = x² – 5x – 24. This means B is false.

When Ellen’s family had completed 70% of a trip, they had traveled 35 miles. How far is the trip overall? (I need a number sentence/A complete sentence)
Answers
Answer:
If Ellen traveled 35 miles and this was 70% of her trip, then 100% of her trip would be 50 miles.
Step-by-step explanation:
You can solve this by setting up a proportion. 35/70 = ?/100. To solve this, cross-multiply 35 and 100 to get 3,500. Divide this by 70 and get 50. This means that 35/70 = 50/100.

Emilio's school, how many students can he expect to have birthdays in July
based on the experimental probability?
Ok
Answers
Answer:153
Step-by-step explanation:
From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.
If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:
= 3/25 × 1280
= 153.6
There will be 153 students expected

Answer:
1. no, 2. yes
Step-by-step explanation:
You need to use the triangular inequality thereom, which goes by if any side lengths are added together, they are greater than the remaining one. So, for number one, although 20+9=29>8 and 20+8=28>9, 9+8<20 since 9+8=17, which is less than 20. For number two, yes because 1) it is a right triangle triple and 2) 3+4=7>5, 4+5=9>3, and 5+3=8>4.
Answer:
Number 1 is Not a triangle so No and you don’t need to classify becuase it’s not aa triangle
Number 2 is a triangle becuase its ta Pythagorean triplet and even if you checK, it adds up.
Step-by-step explanation:
1) So using Pythagorean Theorem
8^2+9^2=20^2
64+91=400
That is not true
2) 3^2+4^2=5^2
9+16=25
That is true
