Answer:
y = (1/3)x
Step-by-step explanation:
If this is truly a line, then we can find its equation using any two of the three given points. If we go from (3, 1) to (27, 9), x increases by 24 and y increases by 8. Thus, the slope of this line is m = rise / run = 8 / 24, or m = 1/3.
Using the point (3, 1) and the slope m = 1/3, the slope-intercept form y = mx + b becomes 1 = (1/3)(3) + b. Thus, b = 0, and the line is y = (1/3)x.
To solve this problem you must divide the total salary by the total hours to figure out how much is earned each hour
$48/6 hours = $8 per hour
$67.50/9 hours = $7.50 per hour

Answer:
105 sq. cm
Step-by-step explanation:
The shortest altitude will ⊥ to the longest side.
A = (1/2)bh
=.5(30)(7)
= 105 sq. cm
Answer:
The radius of the cylinder is: r = 11 yards
Step-by-step explanation:
Given
The height of cylinder = h = 16 yards
Volume of cylinder = V = 6079.04 cubic yards
To determine
The radius of cylinder = r = ?
Using the formula involving volume of the cyliner
V = πr²h
substituting h = 16, V = 6079.04 and π = 3.14
6079.04 = 3.14 (r²) 16
r² = [6079.04] / [(3.14) (16)]
r² = 6079.04 / 50.24
r² = 121


As radius can not be negative.
Therefore, the radius of the cylinder is: r = 11 yards
