Answer:
Surface area:
Step-by-step explanation:
(Imagine there's line separating the rectangle and square)
<u>Rectangle</u>
l × w × h
3 cm × 13 cm × 3 cm
117 cm^3
<u>Square</u>
l × w × h
5 cm × 2 cm × 3 cm
30 cm^3
<u>Total Area</u>
117 cm^3 × 30 cm^3
3,510 cm^3

Answer:
the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)
= -5 = -2x + 15
Step-by-step explanation:
Write an equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5).
Using the slope intercept equation,
y = mx +c
m = slope = 1/2
For two lines to be perpendicular, the product of their slopes is -1
Let the slope of the other line be m2
m1×m2 =-1
1/2×m2 = -1
m2 = -1/(1/2) = -2
Slope of line = -2
For points (10, -5), x = 10, y =-5
-5 = -2× 10 +c
-5 = -20+ c
c = -5+20= 15
the equation of the line that is perpendicular to y = 1/2x + 3 and passes through the point (10, -5)
-5 = -2x + 15
