Step-by-step explanation:

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

A or B think it's A tho not sure

Answer:

B. -4

Step-by-step explanation:

The slope is -8/2 which is the same as -4.

Another way you could do it is down 4 and right 1. That would be -4/1 which is the same as -4.

Answer:

12 scoops of dog food are needed for 6 dogs,

Step-by-step explanation:

Proportions

The number of scoops of dog foods and the number of dogs are proportional variables.

We are given that 10 scoops of dog foods are used for 5 dogs. This gives a proportion of 10/5=2 scoops per dog.

We also know that 16 scoops are used for 8 dogs. The proportion is also 16/8=2 scoops per dog.

Thus, the constant of proportionality is 2.

For 6 dogs, you need to prepare 2*6 = 12 scoops of dog food.

12 scoops of dog food are needed for 6 dogs,

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.

Step-by-step explanation:

Multiply them then divide them by 2

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.

Answer:

g=7

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

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.

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

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.
