A store has clearance items that have been marked down by 30%. They are having a sale, advertising an additional 60% off clearan
Schach [20]

Answer:

28%

Step-by-step explanation:

We get 30% off the original price

The new price is (100-30) = 70$ of the original price

Let x = the original price

The new price is .7x

Now get get an additional 60% off.  We pay (100-60) = 40 percent of the price

Take .7x * .4

The new price is .7*.4 x

                               .28x

This is 28 percent of the original price x

Jamilia has a weather station in her backyard. She uses a rain gauge to track the total rainfall during two storms.
Zielflug [23.3K]

Answer:

1) The graph is linear, because it has an upwards slope of 5, we can tell because 3*5 =15 and 6*5=30.  

2)Real world meaning is the delta change. Hence in this case it's the increase in rain over time. More rain or raining harder as time progresses.

3)It is not linear because the second sample shows a slope of 7.5 meanwhile the third sample shows a slope of 6 which allows us to conclude that it is not linear.

4)The y intercept means the total rain that was present at the start of the recording which essentially means there was no rain when she started the experiment.

Surface area of a cylinder. (see attached image please)
Zolol [24]

Answer:

\large{ \tt{❃ \: EXPLANATION}} :

  • Firstly you need to remember the formula to find out surface area of a cylinder - Surface area of a cylinder = 2πr ( r + h ) where r is the radius of a circular face and h is the height of the cylinder.

  • We're provided : Diameter of cylinder = 12 which means radius ( r ) = 6 cm [ Radius is the half of diameter ] & Height ( h ) = 25 cm & we know pi ( π ) = 22/7.

\large{ \tt{❁ \: LET'S \: SOLVE}} :

\large{\boxed{  \tt{☄TOTAL \: SURFACE \: AREA \: OF\: CYLINDER= 2\pi \: r \: ( \: r + h)}}}

- Plug the values & then simplify !

\large{↦2 \times  \frac{22}{7}  \times 6(6 + 25) }

\large{↦2 \times  \frac{22}{7}   \times 6 \times 31}

\boxed{\large{↦1169.14  \: \tt{ {cm}^{2} }}}

  • Hence , The surface area of given cylinder is 1169.14 cm²
