Answer:
Slope is -3
Step-by-step explanation:
rise over run
The rise is negative so it turns into a negative #
down 3 right 1
-3/1
= -3
Answer:
Area: 3.7 ft²
Ratio: 73.14 : 1
Step-by-step explanation:
Perimeter of an octagon = 8*side
Replacing with perimeter = 7 ft:
7 = 8*side
side = 7/8 ft = 0.875 ft
that is, each side of the model is 7/8 ft length.
Area of an octagon = 2*(1 + √2)*side²
Area of an octagon = 2*(1 + √2)*(7/8)²
Area of an octagon = 3.7 ft²
Perimeter of real gazebo = 8*8 = 64 ft
Then, the ratio of the perimeters (in feet) of the real gazebo floor to the model gazebo floor is 64:0.875. Multiplying each term by 8/7, we get 73.14:1
Answer: 100 rides are needed to break even.
Step-by-step explanation:
C(x)=15x+2000 - x is the number of rides.
R(x)=35 x , where x is the number of rides
35x=15x+2000
35-15x=2000~subtract 15x from both sides~
20x=2000 ~simplify~
x=2000/20 ~dividing both sides by 20~
x=100
1/3 * 1/4
1/12
Hope this helps
Answer:
44°
Step-by-step explanation:
From sin rule:
a / sin A = b / sin B = c / Sin C
3.6 / sin b = 5.1 / sin 100
Cross multiply :
5.1 * sinb = 3.6 * sin 100
Sin b = 3.5453079 / 5.1
Sin b = 0.6951584
b = sin^-1(0.6951584)
b = 44.039
b = 44°
