Reasoning Joanne cannot decide which of two washing machines to buy. The selling price of each is $440. The first is
marked down by 30%. The second is marked down by 20% with an additional 10% off. Find the sale price of each washing
machine. Use pencil and paper. Explain why Joanne should buy the first washing machine rather than the second if the
machines are the same except for the selling price.
The sale price of the first washing machine is $
(Round to the nearest dollar as needed.)

Answers

Step-by-step explanation:

The selling price is $495.

The first washing machine:

- is marked down by 30​%

$495 - 100%

$x - 100% - 30% = 70%

Find the value of x:

x=$495*0.7=$346.50=$347

The second washing machine:

- is marked down by 20​% with an additional 10​% off

$495 - 100%

$y - 100% - 20% = 80%

Find y:

Y=$495*0.8=$396

Now,

$396 - 100%

$z - 100% - 10% = 90%

Find z:

Z=$396*0.9=$356.40=$356

the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.

Answer: the price of the first washing machine is $347 and the price of the second washing machine is $356. Then compare them 347 O 356

It would be < because the sale price of the machine is more.

Step-by-step explanation: The first machine is marked down(in price) by 30% so 440-100 ($440 is = to 100 because its saying the price is 100% no mark downs or anything. Then you find the price is $347 since it has a 30% mark down.

The second machine is marked down by 20% with an extra 10% off, so 440-100 (100% in price) now you find how much that turns into, and it turns into $356

so the first machine is this better one and cheaper one.

least to greatest 11/20,1/2,0.51

Answers

Answer:

1/2, 0.51, 11/20

Step-by-step explanation:

11/20 = 0.55

1/2 = 0.50

0.51

Least to greatest ---> 1/2, 0.51, 11/20

Answer:

1/2, 0.51, 11/20

Step-by-step explanation:

To find out which one is least to greatest, I suggest turning all the numbers into decimals. In order to do this you need to divide the 11 by 20 on a calculator which equals 0.55. Then, we already know that 1/2 = 0.50, and that leaves us with 0.51. So, know we order them.

Find the exact sum or difference.

7/15+9/10

A. 7/9

B. 1 13/15

C. 2 2/9

D. 1 1/15

Answers

Ok so to solve this question you need to find the least common denominator of both fractions which is 30. To get 15 to 30 you have to multiply it by 2. So multiply both sides of the fraction by 2 and you get 14/30 + 9/10
Do the same thing with 9/10 but multiply it by 3
That gives you 14/30 + 27/30 which = 41/30 which is 1 and 11/30
So none of these answers are correct
if you add it’s 1 11/30 and if you subtract it is -13/30 . so therefore they had a typo in the answers or you asked the question wrong sorry. have a great day ! :)

Answer:

[tex]y=1/2x+1[/tex]

Step-by-step explanation:

We have two points: (0, 1) and (2, 2). Let's first look at the b. This is the y-intercept(the y-value when the line intercepts the y-axis). This is 1. Now, let's calculate the slope. The formula for this is rise over run, so we'll take the difference of two y-coordinate points divided by the difference of two x-coordinate points. This gives [tex](2-1)/(2-0)[/tex]. This is 1/2. So, the slope is 1/2.
