Q9.
This question can't be answered. It is necessary to get the dimensions of the figure.
Q10.
Let's find a conclusion having statements step by step.
a) If 3 cans of soup cost a total of $0.85, then 1 can of soup costs:

b) If I get n cans of soup the equation I need to use is multiply the previous equation by n:

The conclusion is: G. Multiplying n by the cost of 1 can.
Q11.
Let's find a conclusion having statements step by step.
a) The company charges $40 to hook a vehicle, so this is a constant variable. Then:
c = 40$
b) There is a second statement that states that for each mile the vehicle is towed the cost increases $1.70, so:
c = $40 + 1.70m
So, the answer is
B.
Answer:
y= 3x-2
Step-by-step explanation:
standard form
y= mx + c
c represents y intercept
m represents slope or gradient
y= 3x-2
The slope is 3 and the y intercept in -2
You must use the trigonometric function.

Answer:
6.7
Step-by-step explanation:
9. 131+106+67+x=360
237+67+x=360
304+x=360
x=56
10. 90+90+146+w=360
180+146+w=360
326+w=360
w=34
Answer:
central angle=18
arc length=2.5 π feet
area of a sector=31.25π square feet
Step-by-step explanation:
Given
wheel radius=25 feet
attached cars=20
Space between cars along the circumference of wheel= 360/20
=18
Finding arc length:
arc length= radius x angle(in radians)
angle in radian = 18 x π/180 = 0.1π radians
arc length = 25 x 0.1π
=2.5π feet
Area of the circle = πr^2
Area of the circle = π(25)^2
Area of the circle = 625π square feet.
As the ratio of the central angle to the full circle angle is proportional to the area of the sector to the complete circle:
central angle/360=area of sector/area of circle
Area of sector= area of circle x 18/360
= 625π(1/20)
=31.25π !
