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

The history museum is hosting a special exhibition on history of flight. The admission ticket for each adult costs $3 and the admission ticket for each child costs $2. On the opening day of the exhibition, 60 tickets were sold for a total of $160. How many adults visited the special exhibition?
Use simultaneous equation for this problem
y= number of adults
x = number of children
3y + 2x = 160
y + x = 60
then we double the second equation
3y + 2x = 160
2y + 2x = 120
we cancel x by elimination
3y - 2y = 160 - 120
y = 40
40 adults visited the special exhibition at the museum
Let x represent the number of admission ticket for adult and y represent the number of admission ticket for child.
60 tickets were sold for a total of $160. Hence:
x + y = 60 (1)
3x + 2y = 160 (2)
Solving equations 1 and 2 simultaneously gives:
x = 40, y = 20
Therefore 40 adults visited the special exhibition at the museum.

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 is the length of side AC of the triangle? Pls hurry
Answer:
Step-by-step explanation:
According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that you cannot draw a triangle that has side lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12.

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

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.

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.
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.
