Step-by-step explanation:
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?
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
Which function has a domain of all real numbers?
A. y = -2(3x)^1/6
B. y = (x +2)1/4
C.y = (2x)^1/3-7
D.y= -x^1/2+5
Answer:
c - (2x)^1/3-7
Step-by-step explanation:
plato
The function [tex]y= -x^{1/2}+5[/tex] has a domain of all real numbers.
Thus, option (D) is correct.
As, Domain is the input value of the function.
In the function [tex]y= -x^{1/2}+5[/tex] .
The square root is defined for all non-negative real numbers (including zero).
When we subtract this square root from 5, the resulting function has a domain of all real numbers.
In options A, B, and C, which involve fractional exponents or roots, option D does not have any restrictions on the values of x.
The function can be evaluated for any real number x, making its domain all real numbers.
Therefore, [tex]y= -x^{1/2}+5[/tex] , has a domain of all real numbers.

Step-by-step explanation:
your goal is to isolate the g
times g/-4 by -4/1 the -4 cancels out the other one so you are just left with g
move the g to the other side of the equation then move the 3 and it to the -5 and then multiply the whole thing but -1 to make the equation positive

Li bought his dog Spot a huge bone that is 15 inches long. Spot chews 4 inches off the bone every day. What is the new length of the bone after 3 days?
Answer:
3 inches
Step-by-step explanation:
If the dog chews off 4 inches every day, you first have to multiply the inches by the number of days, which in this case is 3 x 4, which equals 12. In 3 days, he chewed off 12 of the original 15 inches, leaving only 3 inches left.
pls help just telling me how to do it will help to
Answer:
The Pythagorean Theorem can be used to find the length of the legs and hypotenuse of a triangle. While the distance of a vertical or horizontal line can be counted easily, a diagonal line cannot be determined the same way. A diagonal line, such as the line between the two points shown on the graph, is the hypotenuse of an imaginary right triangle. If you draw the legs of the triangle by drawing straight lines through the points on the graph until the lines meet at a point, you can count the distance of the legs and plug those values into the Pythagorean Theorem.
Step-by-step explanation:
In this case, the meeting point of straight lines drawn through the points is
(-3, -4)
and the distances of the legs of the right triangle are 8 and 6. The theorem is
a² + b² = c²
so 8² + 6² = c² to 64 + 36 = c² to 100 = c² and [tex]\sqrt 100 = \sqrt c^{2}[/tex]
so 10 = c
The distance of the line (hypotenuse) is 10.

4. Emilio asks his classmates what month they were born. He finds that 15
out of 125 classmates were born in July. If there are 1,280 students in
Emilio's school, how many students can he expect to have birthdays in July
based on the experimental probability?
Ok
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

what is he slope of the line and y-intercept PLS HELP ME
Answer:
Slope: 0, y-intercept: -1
Step-by-step explanation:
If a line is completely horizontal, the slope is 0. The equation of this line is:
y = 0x - 1 = -1
The slope is 0 and the y-intercept is -1 because that is the y-coordinate this line intercepts with.
