I think it's the second one on the top, because the dotted one is actually inside the bigger one and you can get a clear representation of the sizes.

What is the value of x? <br> (x + 40)° (3x)°<br><br> A. 20<br> B.35 <br> C. 60<br> D. 70
Olenka [21]
Hello!

We are given the equation below.

x+40=3x

We want to get all of the variables on side. First of all let's subtract 40 from both sides.

x=3x-40

Now we rearrange our equation so the commutative property will work.

x=3x+(-40)
x=-40+3x

Now we subtract 3x from both sides.

-2x=-40

We divide both sides by -2.

x=20

Our answer is A) 20.

I hope this helps!

The picture shows the graphs of the functions expressed by a formula of the following type: y = kx + b.
ollegr [7]

Answer:

line 1: y= 1x+ 2

line 2: y= -1x-0.5

(usually 1 is omitted but I added for clarity)

Step-by-step explanation:

slope (x)= yfinal-yintial/xfinal-xinitial

b= where line intersects y axis

line 1:  (-1,0), (0.5,1.5)

(1.5-0)/(0.5-(-1))

(1.5)/(1.5)

slope= 1x

y=x+ 2

line 2: (-0.5,0), (0.5,-1)

(-1-0)/(0.5-(-0.5))

(-1)/(1)

slope= -1x

y=-x-0.5

Find the volume of a cylinder with height 14.7 cm and diameter 10.5 cm.
velikii [3]

Hello!

The volume of a cylinder is found by using the formula: V = πr²h.

The problem has given us the height of the cylinder, which is 14.7 centimeters, and the diameter which is 10.5 centimeters. The volume of a cylinder requires the radius, so therefore, to find the radius, divide the diameter by half, and that will give the radius.

R = 10.5 / 2

R = 5.25 centimeters

With that radius and the height, we can find the volume of the cylinder.

V = π(5.25)²(14.7)

V = 27.5625(14.7)π

V = 405.17π, 1272.23 (multiplied by 3.14), 1272.88 (multiplied by π)

Therefore, the volume of this cylinder is 1272.88 centimeters³.
