Kareem cannot decide which of two washing machines to buy. The selling price of each is 650​$. The first is marked down by 40​%. The second is marked down by ​10% with an additional ​30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why should buy the first washing machine rather than the second if the machines are the same except for the selling price.

Answers

Answer 1
Answer: this is long divide
Step-by-step explanation: first 585 - 50% = ?
Then do that first total and add or subtact 50 % then add I think or it might be the other way for your real total. it should not change the price for the first machine and that is why would want it. Sorry it's been a while since I have done math use a caluator if you have to
Answer 2

Answer:

The first one cost $390, while the second one cost $409.50

Step-by-step explanation:

650 x .10 =65

650-65=585

585 x .30 = 175.5

585-175.5=409.5

650 x .4 =260

260<409.5

Since the second washing machine is being marked off by 10% first then by 30% percent second, the 30% would be taking away less of the total price than if you did all 40% at one time. I hope this helps

1) find the function AND solution of (y = 5x - 4 when x = 5) (y = - 2/5 x + 3/8 when x = 1/3) (y = 3x + 12 when x = 4)
-
2) Show set of data that is a function using at least 5 domain values and 5 range values. It can be shown
in a format of your choice (graph, table, set notation).

Answers

Answer:

Step-by-step explanation:

1)

y = 5x-4 when x=5

y = 5*5-4

y = 25-4

y = 21

y = -2/5x + 3/8 when x = 1/3

y = -2/5 * 1/3 + 3/8

y = -2/15 + 3/8

y = -6/120

y = -1/20

y = 3x + 12 when x = 4

y = 3*4 + 12

y = 12 + 12

y = 24

Predict how many times you would expect to land on a 5 if you roll a standard number cube 36 times.

Answers

Since we're dealing with probability, you have a 1/6 chance to land the dice on 5. and since 6 is a multiple of 36, we can conclude that

1/6 = ? / 36

6 x 6 = 36

6 x 1 = 6

Answer: you should approximately roll a 5 about 6 times

Answer:

6

Step-by-step explanation:

The probability of getting a '5' on one toss is 1/6.  Thus, if you roll the cube 36 times, the predicted number of '5's will be 36(1/6) = 6

The correct option is B.

What is a cylinder?

A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.

Given:

Sandra bought coffee in a cup shaped like a cylinder with a radius of 10 centimeters and a height of 20 centimeters.

Sandra fills the cup with coffee, but she leaves 5 centimeters of space at the top to have room for cream.

The volume of coffee in her cylindrical cup,

= (3.14) (100) (15)

= 4710 cubic centimeters.

Therefore, the volume is, 4710 cubic centimeters.
