Happy Paws charges $20.00 plus $4.50 per hour to keep a dog during the day. Woof Watchers charges $11.00 plus $5.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
The equation is: ______=______
The total cost of the services will be equal at __ hours.
Answer:
The equation is: 20 + 4.5h = 11 + 5.75h
The total cost of the services will be equal at 7.83 or 8 hours.
Step-by-step explanation:
This equation is correct because it shows that these two scenarios equal the same amount of money when there is a certain amount of hours, or "h."
Here is how we solve the equation;
20 + 4.5h = 11 + 5.75h <-----Here is the original equation.
Service A Service B
1. 20 - 20 + 4.5h = 11 - 20 + 5.75h
2.4.5h - 5.75h = -1.15h -9 + 5.75h/5.75 =
3. -1.15h/-1.15 = h 9/-1.15 = 7.83
h = 7.83 or 8 hours when rounded to the nearest hour

Consider the graph of the function f(x)=10^x.
Using graph, the value of g(x) = 8 and the y- intercept at the point (0,-1).
What is graph?A graph is a "mathematical representation of a network and it describes relationship between lines and points".
According to the question,
f(x) = [tex]10^x[/tex]
g(x) = -4f(x) +12
g(x) = -4 (10ˣ) +12
The graph intersect at y-axis then x-coordinate should be zero.
Let take any two points on y-axis (0, 1) and substitute g(0) = -4 (10⁰) + 12
= 8
Hence, the value of g(x) = 8 and the y- intercept at the point (0,-1).

Answer:
No, because it fails the vertical line test ⇒ B
Step-by-step explanation:
To check if the graph represents a function or not, use the vertical line test
Vertical line test: Draw a vertical line to cuts the graph in different positions,
if the line cuts the graph at just one point in all positions, then the graph represents a functionif the line cuts the graph at more than one point in any position, then the graph does not represent a functionIn the given figure
→ Draw vertical line passes through points 2, 6, 7 to cuts the graph
∵ The vertical line at x = 2 cuts the graph at two points
∵ The vertical line at x = 6 cuts the graph at two points
∵ The vertical line at x = 7 cuts the graph at one point
→ That means the vertical line cuts the graph at more than 1 point
in some positions
∴ The graph does not represent a function because it fails the vertical
line test

At a baseball game, 6 hotdogs cost $27. What is the cost of 1 hotdog? How many hotdogs can you buy for $18
Answer:
What is the cost of 1 hotdog?
Answer: $4.50
How many hotdogs can you buy for $18?
Answer: 4
Step-by-step explanation:
If $27 can buy you 6 hot dogs, to find the cost of one, we just divide.
27 divided by 6 = 4.5 ($4.50)
So 1 hotdog costs $4.50
If 1 hotdog is $4.50, and we want to know how much we can buy for $18, then we divide again.
18 divided by 4.5 = 4
So for $18, we can buy 4 hotdogs

HELP! ASAP! 3x - 4y = -7 and 4x + 3y = 24 solve for x and y
Answer:
x = 3
y = 4
Step-by-step explanation:
3x -4y = -7
4x + 3y = 24
write the first equation in terms of y
3x - 4y = -7
3x + 7 = 4y
3x/4 + 7/4 = y
now substitute that into the second equation
4x + 3y = 24
4x + 3(3x/4 + 7/4) = 24
4x + 2.25x + 5.25 = 24
6.25x + 5.25 = 24
6.25x = 24 - 5.25
6.25x = 18.75
x = 18.75/6.25
x = 3
last step, substitute x for 3 in the equation.
y = 3x/4 + 7/4
y = 3*3/4 + 7/4
y = 9/4 + 7/4
y = 4

Mr. Jackson gave an exam worth 50 points.
The mean score on the exam was 38, and the standard deviation was 4.
Mr. Jackson also reported his students’ z-scores.
Corey’s z-score was –1.75. This means that Corey scored points on the exam.
Z = (score - mean)/sd
-1.75 = (x - 38)/4
Multiply both sides by 4:
-7 = x -38
Add 38 to both sides:
x = 31
He scored a 31 points on the exam

Enter the number of rows needed and the number of seats that will be left over.
826 seats and 42 seat per row

Answer:
Assuming the covered digits are _
The sum is 826.
243 + 1_7 + _26 = 826
The objective is to determine the sum of the two unknown digits
So; we need to think about what number can we add put in 1_7 to determine the covered digit in _26
From ; 1_7 , we have the choice to pick from 0 - 9
Assuming the covered digit is 0; let's check if we are right
So; 243 + 107 + _26 = 826
350 + _26 = 826
_26 = 826 - 350
_26 = 476
So; the covered digit is in the position of 4 , but it doesn't tally together
i.e 426 is not the same as 476, which makes our assumption to be wrong.
Let consider the covered digit to be 5 for example.
So; 243 + 157 + _26 = 826
400 + _26 = 826
_26 = 826 - 400
_26 = 426
The covered digit is in the position of 4
SO;
426 = 426
Here , our assumption is right.
As such , the covered digits are 5 and 4
The sum of the two covered digits are = 5 + 4 = 9

Mr. Blanco used 15.75 yards of fabric to make 7 costumes for the school play. How many yards of fabric did he use per costume?
Answer:
2.25 yards per costume
Step-by-step explanation:
if you want to find the unit rate of something put it into a fraction which is also considered dividing. Like if you want to figure out miles per hour or ounces per cup, just divide miles by hour, or divide ounces per cup to get your final answer. In this case divide 15.75 yards of fabric by 7 costumes to get your answer.
Answer:
2.25

Pam, Wesley, and Diana added up how many miles they walked together.
In one week, they walked 38 miles.
Of those miles, Pam walked 13.
How many miles did Diana walk?
Answer:
12.5
Step-by-step explanation:
If they walked 38 miles and Pam walked 13, subtract 38 from 13, you then get 25. Then, divide that by 2. 25 divided by 2 is 12.5. That is your answer, I believe. Please make this the brainliest answer.

3. A googol is a very large number expressed as
10100. Ms. Rogers asked her students to
determine which number is larger, a googol
or 10010. Explain how her students might use
the idea of repeated factors in order to find
the solution.
Answer:
10^100 is larger than 100^10.
Step-by-step explanation:
10^100 compared to 100^10, we have 10^100 greater. 100^50 would equal to 10^100, as 10^2=100. 10^100 would be much more than 100^10.

Given that 529 × 3.8 = 2010.2
write a division with an answer of 5.29
Answer:
Step-by-step explanation:
2010.2/380= 5.29
Answer:
5.29 = 20.102 / 3.8.
Step-by-step explanation:
529 × 3.8 = 2010.2
So 529 = 2010.2 / 3.8
We need 5.29 on the left so we divide both sides by 100:
5.29 = 2010.2 / (3.8*100)
5.29 = 20.102 / 3.8
