Answer:

Step-by-step explanation:

surface area = bh + L(s1 + s2 + s3)

where b = 24 ft.

h = 9 ft.

s1 = 15 ft.

s2 = 15 ft.

s3 = 24 ft.

L = 40 ft.

<u>plugin values into the formula:</u>

A = 24*9 + 40(15 + 15 + 24)

= 216 + 40(54)

= 2,376 ft²

29,700 / 12 =$2,475 per month.

Multiply his monthly pay by 7%:

2,475 x 0.07 = $173.25 into his 401(k) per month.

A line passes through the origin and has a slope of -3 what is the equation of the line that is perpendicular to the first line

Marianna [84]

Answer: $y=\frac{1}{3}x+3$

Step-by-step explanation:

The equation of the line is Slope-intercept form is:

$y=mx+b$

Where "m" is the slope and "b" the y-intercept.

The slopes of perpendicular lines are negative reciprocal.

Then, if the slope of the first line is -3, the slope of the other line must be:

$m=\frac{1}{3}$

Substitute the point (3,4) into the equation and solve for b:

$4=\frac{1}{3}(3)+b\\ 4-1=b\\b=3$

Then the equation of this line is:

$y=\frac{1}{3}x+3$
