Answer:

150 in^2

Step-by-step explanation:

The ends have the smallest surface area.  The total surface area of the ends is thus 2(3 in)(4 in) = 24 in^2

The top and bottom together have the total surface area 2(9 in)(3 in) = 54 in^2.

Finally, the front and back surface areas together are 2(9 in)(4 in) = 72 in^2

Thus, the total surface area is (24 + 54 + 72) in^2 = 150 in^2

A pair of shoes are on sale for 25% off their regular price of $180. Students at Pikesville Middle can get an additional 10% off
Nikolay [14]

Answer:

$121.5

Step-by-step explanation:

$180 × 0.25 = $45 <-- because it is a discount, we will subtract

$180 - $45 = $135 <-- price with 25% discount

$135 × 0.10 = $13.5

$135 − $13.5 = $121.5

2. Perpendicular to y=1/3X-5 and goes through the point (3, -5)
Rudiy27

Answer:

Step-by-step explanation:

To be perpendicular the product of the two slopes is equal to negative one.

m1(m2)=-1, in this case the slope of the reference line is 1/3 so the other line will have a slope

m/3=-1

m=-3 so our perpendicular line is

y=-3x+b, using point (3,-5) we can solve for the y intercept b

-5=-3(3)+b

-5=-9+b

b=4 so the completed perpendicular line passing through point (3,-5) is

y=-3x+4
