Answer:

B) 345.6 m^2

Step-by-step explanation:

Surface Area of Cylinder

= 2(Area of Base) + Area of Curved surface

= 2(pi × 5^2) + 2pi(5)(6)

= 345.6 m^2

Answer:

The answer would be 345.6

Step-by-step explanation:

The reason why i said that is because to find the surface area of a cylinder, you would have to do A=2 π r h+2 π r 2 ( Spaced it out so you can see. BTW the r stands for radius and h stands for height. If you do the formula correctly, you would get 345.6

I don’t understand this and I did take notes on this on the computer but I still don’t understand it.

Answer:

I'[−3, −2], Q'[2, 0], ?'[0, 1], E'[−3, −1]

Step-by-step explanation:

The line of reflection is at y = −2, so looking at the line and where the coordinates of the shape are, you will have this:

I[−3, −2] → I'[−3, −2] (on the line, so it remains the same)

Q[2, −4] → Q'[2, 0]

?[0, −5] → ?'[0, 1]

E[−3, −3] → E'[−3, −1]

What is the slope of the line determined by the equation -1/2x+3/4y=0

kvasek [131]

Answer:

The slope is 2/3

Step-by-step explanation:

-1/2x+3/4y=0

To find the slope, we need to get the equation in the form y= mx+b

Add 1/2x to each side

-1/2x+ 1/2 x+3/4y=0+1/2x

3/4 y = 1/2x

Multiply by 4/3 to isolate y

4/3 * 3/4 y = 4/3 * 1/2 x

y = 2/3 x

The slope is 2/3 and the y intercept is 0

A $450 TV is discounted 10%, and then another 10% a week later. Explain why taking 20% off the original price will not help you

ExtremeBDS [4]

Answer:

Because the price did not stay the same when they discounted it by 10% percent before.

Step-by-step explanation:

10% percent of 450 is 45 so Subtracting that from 450 would give you,405.

They deducted another 10% percent a week later 10 percent of 405 would be 40.5 so you would subtract that from 405 which would make it 364.5

If you took 20% off originally then 20% of 450 is 90 so subtracting that would make 450 into 360 which is different from 364.5
