A 3-yard roll of wrapping paper costs $13.14. What is the price per foot?
Answer:
Step-by-step explanation:
1 yard is equal to 3 feet.
since you have 3 yards, it'll be 9 feet.
13.14/9 to get your answer
or $1.46 per foot
The price per foot of wrapping paper is $1.46.
First, we need to convert 3 yards to feet. There are 3 feet in 1 yard, so 3 yards is equal to 3 * 3 = 9 feet.
The price per foot is simply the total price divided by the number of feet. In this case, the total price is $13.14 and the number of feet is 9, so the price per foot is:
price per foot = $13.14 / 9 feet
= $1.46 per foot
Therefore, the price per foot of wrapping paper is $1.46.

Answer:
60
Step-by-step explanation:
The exterior angles of the polygon are the supplement of the interior angles, so are ...
180° -174° = 6° . . . . measure of each exterior angle
The sum of exterior angles is 360°, so ...
n(6°) = 360°
n = 360°/6° = 60
The polygon has 60 sides.
Answer:
The polygon has 60 sides.
Step-by-step explanation:
Each interior angle = 174°
Each exterior angle = 180° - 174° = 6°
Sum of all exterior angles = 360°
6x = 360° (x = no. of exterior angles)
x = 360°/6
x = 60
If it has 60 exterior angles it has 60 interior angles.

What are the x and y intercepts
Answer:
x= -27 y=18
Step-by-step explanation:
plug in zero for x to find y and plug in zero for y to find x
Answer: The x-intercept is (-27,0)
The y intercept is (0,18)
Step-by-step explanation:
For the x- intercept, Substitute 0 for y and solve for x
-2x + 3(0) = 54
-2x + 0 = 54
x = 54/-2
x = -27
For the y -intercept, Substitute 0 for x and solve for y
-2(0) + 3y = 54
0 + 3y = 54
y = 54/3
y = 18
