Answer:
The constant of proportionality determines the steepness of the straight-line graph that represents a proportional relationship. The steeper the line is, the greater the constant of proportionality.
Step-by-step explanation:
The steeper the graph, the larger the constant of proportionality.
This is because y = kx represents any direct proportion equation. Note how k plays the role of the slope. Also, k = y/x. The steeper the graph, the larger the slope value will be.

Greg earns 18.5$ in a hour
2. /
1387.5÷18.5 =75h
75h>60h
So yes they will buy him

Your long distance telephone provider offers two plans. Plan A has a monthly fee of $15 and $0.25 per minute. Plan B has a monthly fee of $20 and $0.05 per minute. Write and solve an equation to find the number of minutes that you must talk to have the same cost for each of the plans.
Answer:
15+ 0.25x = 30
-15 -15
0.25x=15
x=60
So for plan a, you can talk for 1 hr for $30
20+0.05x = 30
-20 -20
0.05x=10
200x=10
Plan B you can talk for 200 mins for 30 dollars.

Answer: The blue car gets 26 2/3 mpg
The silver car gets 34 mpg
The silver car can travel farther on one gallon of gas. By about 7 1/3 miles.
Step-by-step explanation:
Divide miles by amount of gas.
Blue: 35 1/2 ÷ 1 1/2 = mpg
71/2 ÷ 3/2 => 71/2 × 2/3= 71/3
Simplify 26 2/3 mpg
Silver: 27 1/5 ÷ 4/5 =>136/5 × 5/4
136/4 Simplified = 34 mpg
Priscilla’s grandmother’s fruit salad recipe calls for one part apple, one part orange, four parts strawberry, two parts cherry, and three parts grape.

Therefore, the ratio of quantity of apples with the quantity of grapes = [tex]1 : 3.[/tex]
The sentence comparing the quantity of apples with the quantity of grapes in Priscilla’s grandmother’s fruit salad recipe is given below:
For every one apple, there are three grapes in Priscilla’s grandmother’s fruit salad recipe.
Part B
The quantity of apples in recipe = one part = 1.
The quantity of strawberries in recipe = four parts = 4.
Therefore, the ratio of quantity of apples with the quantity of strawberries = [tex]1 : 4.[/tex]
The sentence comparing the quantity of apples with the quantity of strawberries in Priscilla’s grandmother’s fruit salad recipe is given below:
For every one apple, there are four strawberries in Priscilla’s grandmother’s fruit salad recipe.
Part C
The quantity of cherries in recipe = two parts = 2.
The total amount of fruits in the recipe = [tex]1 part of apple + 1 part of orange + 4 parts of strawberries + 2 parts of cherry + 3 parts of grape[/tex] = 11.
Therefore, the ratio of quantity of cherries with the total amount of fruits = [tex]1 : 11.[/tex]
The sentence comparing the quantity of cherries with the total amount of fruits in Priscilla’s grandmother’s fruit salad recipe is given below:
For every two cherries, there are a total of 11 part of fruits in Priscilla’s grandmother’s fruit salad recipe.
Part D
The total amount of fruits in the recipe = [tex]1 part of apple + 1 part of orange + 4 parts of strawberries + 2 parts of cherry + 3 parts of grape[/tex] = 11.
The quantity of oranges in recipe = one part = 1.
Therefore, the ratio of the total amount of fruits with the quantity of oranges = [tex]11 : 1.[/tex]
The sentence comparing the total amount of fruits with the quantity of oranges in Priscilla’s grandmother’s fruit salad recipe is given below:
For every one orange, there are a total of 11 part of fruits in Priscilla’s grandmother’s fruit salad recipe.

A cylindrical log has a length of 3 meters and a radius of 3/20 of a meter. how much space does the log occupy?
A. 9/20 PI m^3 B. 3/20 PI m^3 C. 27/400 PI m^3 D. 9/400 PI m^3
Answer:
0.212 sq-m
Step-by-step explanation:
(refer to attached)
Volume of a cylinder is given by
V = πr² h, where 3 is the radius and h is the height
in this case, h is given as the length of the cylinder of 3 m
r is given to be (3/20)m
hence,
V = πr² h
V = π(3/20)² (3)
V = π (9/400) (3)
V = π (27/400) (assuming π = 3.142)
V = 3.142 (27/400) = 0.212 sq-m
