I'm assuming it is asking for surface area.

SA = 2(lw) + 2(hw) + 2(lh)
SA = 2(3*4) + 2(4*8) + 2(3*8)
SA = 2(12) + 2(32) + 2(24)
SA = 24 + 64 + 48
SA = 136 square feet

HELP PLEASE
Anna [14]
For a cone, the equation for volume would be
V = π r^2 h/3.

( volume = pi x radius squared x height / 3)

To find the volume for this question, you would set up the equation like this:

V = π x 2^2 x 12 / 3

Then, following the order of operation, you would do the following:

V = π x 4 x 12 / 3

(You get the 4 from 2 squared)

V = π x 4 x 4

(You get the second 4 from dividing 12 by 3)

V = π x 16

(You get 16 from multiplying 4 and 4)

V = 16π

(You get 16π from multiplying 16 and π, and the number is always in front of the π, so you would never get a π16, it would only be 16π)

So, your volume would be 16π, which is answer D.

Write an equation in standard form of the line that passes through the given point and has the given slope. (5,0) m=4/3
sveticcg [70]

\text{The standard form of a line:}\ Ax+By=C

\text{The point-slope form:}

y-y_1=m(x-x_1)

\text{We have the point (5, 0) and the slope}\ m=\dfrac{4}{3}

\text{substitute:}\\\\y-0=\dfrac{4}{3}(x-5)\qquad|\text{use distributive property}\\\\y=\dfrac{4}{3}x-\dfrac{20}{3}\qquad|\text{multiply both sides by 3}\\\\3y=4x-20\qquad|\text{subtract 4x from both sides}\\\\-4x+3y=-20\qquad|\text{change the signs}\\\\\boxed{4x-3y=20}

One day last week, 6 teachers joined 5/7 of the members of the running club in an after-school run. Priya counted a total of 31
Blababa [14]

Answer:

The running club has 35 members

Step-by-step explanation:

Let

x ----> the total members of the running club

we know that

The total members of the running club multiplied by 5/7 plus 6 must be equal to 31 people

so

\frac{5}{7}x+6=31

Solve for x

\frac{5}{7}x=31-6

\frac{5}{7}x=25

x=25(7)/5

x=35\ members

therefore

The running club has 35 members
