Use a net to find the surface area of the right triangular prism shown:
erma4kov [3.2K]

Answer:

256 ft²

Step-by-step explanation:

Net comprises: 2 equal triangles, 2 equal rectangles and 1 smaller rectangle

Area of a triangle = 1/2 x base x height

⇒ area of one triangle = 1/2 x 10 x 7 = 35 ft²

Area of a rectangle = width x length

⇒ area of larger rectangle = 6 x 12 = 72 ft²

⇒ area of smaller rectangle area = 6 x 7 = 42 ft²

⇒ Total area = (2 x 35) + (2 x 72) + 42 = 256 ft²

A right cylinder has a radius of r inches and height of 2r inches.
Bess [88]

Answer:

the volume is 6.28r^{3}in^{3}

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cylinder.

Given data

Volume v =  ?

Radius r =  r in

Height h=   2r in

We are expected to solve for the volume of a cylinder, given the above data we can substitute it in the formula for volume of a cylinder to obtain our result

we know that the expression for the volume of a cylinder is

v= \pi r^{2} h

v= 3.142*r^{2} *2r\\v= 3.142*2r^{3} \\v= 6.28r^{3} in^{3} \\

Hence the volume in terms of the radius is 6.28r^{3}in ^{3}

The graphs of the linear functions f and g are shown above. If h(x)=f(x)+g(x), then h′(x)=
SpyIntel [72]

Based on the graph,

     f(x) = 1/2x+3

    g(x) = -x+4

so, h(x) = -1/2 x +7

Since h'(x) is the derivative or slope of h(x) and h is a line,

h'(x) = -1/2, Answer C.

Bethany is paid time-and-a-half for each hour she works above her normal 40 hours each week. Last week, Bethany worked 44 hours
scoray [572]

Answer : $18.75

Bethany is paid time-and-a-half for each hour she works above her normal 40 hours each week. Last week, Bethany worked 44 hours and her gross pay was $575.

Total hours worked = 44 hours

Normal 40 hours + 4 hours extra

Let x be the amount earned for 1 hour for regular 40 hours

1.5x be the amount earned for extra hours

40 (amount earned for normal hours ) + 4(amount for extra hours ) = gross pay

40x + 4(1.5x) = 575

40x + 6x = 575

46 x = 575

Now divide both sides by 46

x = 12.5

1.5x is the amount earned for extra hours

1.5 * 12.5 = 18.75

Bethany earn for each hour of overtime she worked is $18.75
