Happy Paws charges $20.00 plus $3.50 per hour to keep a dog during the day. Woof Watchers charges $10.00 plus $4.75 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.
Answer:
8 hours
Step-by-step explanation:
Create an equation that sets the costs equal to each other, where h is the number of hours
3.5h + 20 = 4.75h + 10
Solve for h
3.5h + 20 = 4.75h + 10
20 = 1.25h + 10
10 = 1.25h
8 = h
So, it will take 8 hours for the costs to be equal

Answer:
180
Step-by-step explanation:
This basically means that one and a half of the amount of people that took a biking class ran on the treadmill.
There are two ways to solve
1. [tex]\frac{150*120}{100}[/tex]
2. [tex]120+\frac{120\\}{2}[/tex]
To do the first one:
1. Multiply the values in the numerator
18000/100
2. Divide
180
To do the second one:
1. Divide the fraction
120 + 60
2. Add
180
Mr. Dieter wants to tile the family room in his basement. He has selected a pattern of square tiles that measure 9 inches by 9 inches each. The shape of the floor to be tiled is shown below. a. What is the area of the family room in square feet? b. How many of the 9 inch by 9 inch tiles will it take to cover the floor? (NOTE: You will need to convert the area in Part a from square feet to square inches.) c. If the tile is sold only in boxes of 12 tiles per box, how many boxes will Mr. Dieter have to buy to tile the family room?
Answer:
146 ft²
21.6 tiles
1.8 boxes
Step-by-step explanation:
Please find attached an image of the family room used in answering this question
the family room has the following shapes : 2 triangles and one rectangle
the area of the family room can be determined by calculating the area of each of the shape and adding the 3 areas together
area of a rectangle = length x breadth
16 x 7 = 112 ft²
Area of a triangle = 1/2 x base x height
Area of the smaller triangle = (1/2) x 4 x 3 = 6 ft²
Area of the bigger triangle = (1/2) x 8 x 7 = 28 ft²
Sum of the areas = 112 + 6 + 28 = 146 ft²
b.
1. First convert the area of the room to inches
1 ft = 12 in
146 x 12 = 1752 in²
2. the next step is to determine the area of the tile
area of a square = length²
9² = 81 in²
3. Divide the area of the room by the area of the tile
1752 / 81 = 21.6 tiles
c. total number of boxes that would be bought = 21.6 /12 = 1.8 boxes

Answer: B
Step-by-step explanation:
∠A and \angle B∠B are complementary angles. If m\angle A=(6x+22)^{\circ}∠A=(6x+22) ∘ and m\angle B=(7x+16)^{\circ}∠B=(7x+16) ∘ , then find the measure of \angle B∠B.
Answer: B = 44
Step-by-step explanation:
The measure of ∠B = 44°.
We have two angles ∠A and ∠B which are complementary of each other.
We have to find the measure of ∠B.
What are Complementary angles?Two angles are said to be complementary if their sum is equal to 90°.
Mathematically - x + y = 90°
According to the question -
∠A = (6x+22)°
∠B = (7x+16)°
Now, ∠A and ∠B are Complementary angles. Therefore -
∠A + ∠B = 90°
(6x + 22) + (7x + 16) = 90
13x + 38 = 90
13x = 52
x = 4
Therefore -
∠B = 7x + 16 = 7 x 4 + 16 = 44°.
Hence, the measure of ∠B = 44°.

Zeke earned 23 extra credit points. Sofia earned e fewer extra credit points than Zeke. Write
an expression that shows how many extra credit points Sofia earned.
Answer:
s = 23 - e
Step-by-step explanation:
In this expression, s is equal to the amount of extra credit Sofia earns. She earns e less points than the 23 points Zeke earns.
So, s (Sofia's points) = 23 (Zeke's points) - e (the difference in points).
The expression is s = 23 - e.
Good luck ^^
