Answer:
Susan works as a plumber. She takes calls and goes to people's houses to fix things. She charges $15 flat fee just for coming to your home and $30 for every hour she is there repairing. Susan also has a competitor, Carla. She doesn't work as much as Susan and only charges $20 no matter what amount of time she is repairing. The inequality is 30x+15>20. The answer to this solution is x>1/6. You solve this by moving the constant to the right and changing it's sign, subtracting the two numbers, and dividing both sides by 30x to get x>1/6. On the number line it will appear as a closed circle on 1/6 on the number line (less than one) and an arrow going right.

Barbara plotted an elevation below sea level on a number line and labeled it A. She plotted Point B above 0, a distance that is exactly as far from 0 as Point A is. Explain what you know about Point B.
thx
Answer: Because Point A is negative and the same distance below 0 on the number line as Point B is above it, Point B is both positive and the opposite of Point A.
Answer:
both
Step-by-step explanation:
Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown:
A support structure is shown in which a right triangle PQR is formed with the right angle at Q. The length of PQ is shown as 14 feet, and the length of QR is shown as 9 feet..
Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer stating the theorem you used. Show all your work. (5 points)
Part B: The length of rod PR is adjusted to 18 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)
Answer:
Triangle PQR is a right triangle therefore you can use the pythagorean theorem to find the length of PR which is the same as the hypothenuse
Step-by-step explanation:
Theorem:
(QP)² + (QR)² = (PR)²
(6)² + (14)² = 232 ⇒ (PR)² = 232 then PR = √232 = 15.23
If PR is adjusted to 16 feet then we use the Pythagorean theorem again to find the height QR
(QR)² + (14)² = (16)²
(QR)² = 256 - 196 = 60 ⇒ QR = √60 = 7.75.

A dress cost p dollars. An 8% sales tax must be added to the dress. Martha wants to multiply the cost of the dress by 0.08 to find the tax and then add it to the cost of the dress. Esther thinks that the cost of the dress should be multiplied by 1.08. The expressions for the two methods are shown below.
Martha: p+0.08p
Esther: 1.08p
Are the two expressions equivalent? Explain.
What does this mean in terms of the methods outlined by Martha and Esther?
Answer:
no they aren't equivalent Martha's expression is in the hundredths instead of the tenths
IT means that Esther's methods are much more easy and effect compared to Martha's

WHAT DID HE DO WRONG
333/1,000 = 0.333 =0.3
Answer:
He dropped 2 of the 3 in the last simplification and you can't do that. You can't just get rid of two of the values that make up the number. The farthest you are able to simplify is 0.333.
He thought the 0.333 was continuing, so he rounded. However, the answer ISN'T continuing, so he shouldn't round.

Harper knows he is 50 yards from school. The map on his phone shows that the school is 2/3 inch from his current location. How far is Harper from home, if the map shows the distance as 3 inches?
Actual distance of the Harper from the school = 50 yards.
According to map the distance from the school = 34 inch.
We could say 34 inches represents 50 yards.
So, 1 inches could be represented by 50/34 = 25/17 yards.
In order to find the actual length of 3 inches in yards, we need to multiply 1 inches value of yards by 3.
Therefore, 3 inches = 3* 25/17 = 75/17 = 4 7/17 yeards in decimals 4.412 yards approximately.
Therefore, Harper from home is 4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.
Answer:
Actual distance of the Harper from the school = 50 yards.
According to map the distance from the school = 34 inch.
Step-by-step explanation:
If one inch represents 12 feet, what dimensions would you use to make a scale drawing of a building 75 feet by 80 feet.????
Answer:
6.25 inch by 20/3 inch (6.67 inch).
Step-by-step explanation:
Answer:
1 inch = 12 feet
length of the drawing building=75 feet
12 feet = 1 inch
75 feet= 75 / 12
=6.25 inches
Breadth of drawing building= 80 feet
12 feet=1 inch
80 feet= 80/12
=6.66 inches

The table shows the number of cups of caramel required for different amounts of flour in a caramel cookie recipe. The ratio of cups of caramel to cups of flour is constant.
Cups of Flour 5 10 20 25
Cups of Caramel 3 6 c 15
Let c = cups of caramel needed when using 20 cups of flour
Which proportion can be used to determine the value of c?
A.
B.
C.
D.
Answer:
c=12
Step-by-step explanation:
if 3 cups of caramel is 5 cups of flour we can count/multiply by 5's t get the answer. 3:5 can be scaled from using first the cups of flour to determine how much we must scale by to get 20. Then we scale using the multiples of 3.
3:5 can be scaled to 10:12
Answer: The answer is C) 20/c = 5/3

Which equation represents a proportional relationship?
y = 5x + 1
y=15x
y=−x
y=−5(x+1)
Answer:
y = 15x
Step-by-step explanation:
A proportional relationship is of the form
y = kx ← k is the constant of proportionality
The only relationship fitting this relationship is
y = 15x with k = 15
y=15x
