Kareem cannot decide which of two washing machines to buy. the selling price of each is $495. 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 kareem 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 $
nothing.
(round to the nearest dollar as needed.) (then find the second one )

See explanation

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:

The second washing machine:

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

$495 - 100%

$y - 100% - 20% = 80%

Find y:

Now,

$396 - 100%

$z - 100% - 10% = 90%

Find z:

Thus, 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.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
