Set up and solve an equation of ratios. Comparing shadow lengths, we get 100/6; comparing heights, we get x/8. Set these two ratios equal to one another and solve the resulting equation for x:
100 x
----- = ------ Then 6x=800, and x = 800 feet^2 over 6 feet. Your answer
6 8
must have the unit of measurement "ft."
Answer:
Step-by-step explanation:
5y + 3 + 2y - 7
=7y - 4
Answer:
1/2.25 or 4/9
Step-by-step explanation:
Answer:
y = -⅔x + ²²/₃
Step-by-step explanation:
1. Calculate the slope of EF
Assume E is at (-2, 5) and F is at (1, 3).
m₁ = (y₂ - y₁)/(x₂ - x₁) = (3 - 5)/(1 -(-2)) = -⅔
2. Calculate the slope of the parallel line
m₂ = m₁ = -⅔
3. Calculate its y-intercept
y = mx + b
6 =-⅔(2) + b
Simplify
6 = -⁴/₃ + b
Add ⁴/₃ to each side
b = 6 + ⁴/₃ = ¹⁸/₃ + ⁴/₃ = ²²/₃
The y-intercept is at (0,²²/₃).
4. Write the equation for the line
y = -⅔x + ²²/₃
The diagram shows EF in red. The parallel line in black passes through (2, 6) with a y-intercept at (0,²²/₃).
If the total sales are $23152.81 and the sales tax is 5%, take the total sales divided by 1.05 $23152.81/1.05 = $22050.30 (gaves you the sales) to get the sales tax, subtract the total sales from the sales= Sales are $22050.30Tax is $1102.51 hope this helps :)
