19. Macy bought new tires for her car. She chose tires that cost $73 each. However, the tire store was offering a Buy 3Get 1 Free Sale. After this special sale, she had to pay % sales tax . What was , Macy's final cost for all 4 tires?

First we need to turn 3 1/3 into an improper fraction:

3 1/3 = 10/3

Because we are dividing, multiply 57 my the reciprocal (the faction flipped upside down) of 10/3:

57 x 3/10

Which can also be written as:

57/1 x 3/10

Now we just multiply:

171/10

Therefore 171/10 is ur answer

Hope this helped :)

Answer:

27 cups

Step-by-step explanation:

Amount of orange juice in the mixture = 3 quarts

Therefore, number of cups of orange juice = 3 × 4 cups [Since, 1 quarts = 4 cups]

                                                                        = 12 cups

Amount of milk in the mixture = 5 pints

Therefore, amount of milk in cups = 5 × 2  [Since, 1 pint = 2 cups]

                                                         = 10 cups

Amount of pineapple juice in the mixture = 5 cups

Amount of mixture = Amount of Orange juice + Amount of pineapple juice + Amount of milk

= 12 + 10 + 5

= 27 cups

Therefore, total amount of smoothies = 27 cups

the formula of circumference is 2×radius×pi.. so given=radius=7.5

pi=3.14

2×7.5×3.14=47.1

Answer:

+ 5 or - 5

Step-by-step explanation:

Using pythagoras theorem;

y^2 = 3^2 + 4^2

y^2 = 9 + 16

y^2 = 25

y = [tex]\sqrt{25}[/tex]

y = + 5 or - 5

Answer:

Its 0 because thats the only value not bigger than 4

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Any value to the left of 4 is a solution to x < 4

The only value on the list that is left of 4 is 0 → B

Answer:

Step-by-step explanation:

3⅔ = 11/3

1¼ = 5/4

length = area ÷ width

= (11/3) ÷ (5/4)

= (11/3) × (4/5)

= 44/15

= 2 14/15 inches

Answer:

x= -7/5

y=-6/5

one solution I believe. Hope this helps!

Answer:

$1,800

Step-by-step explanation:

If Mo pays 1/2 of the rent then he is paying 50%. Charlie is paying another 25%. This leaves the remaining 25% that Andy pays. Since Andy's payment amount is 450 then that means that 450 is equal to 25% of the total rent. Therefore, we simply need to multiply this amount by 4 to get the 100% of the overall rent.

450 * 4 = $1,800

Finally, we can see that the total rent amount is $1,800

Answer:

Yes they are equivalent.

Step-by-step explanation:

since 16 times 3/4 is 12 and a times b is ab. Put those together and you get 12ab. Since 3/4 of 24 is 18 and the variable is a, it is 18a. Hope this helped.

Answer:

Step-by-step explanation:

yes congruent, by AAS

the angles are stating , w/ the little red lines that they are the same.. so we know two angles of the triangles are the same, and we also know that one side touching is the same.   so yes.. AAS.  

Answer:

about 3.2 gallons. (3.2, 12)

Step-by-step explanation:

If gas costs $3.75 per gallon and Berto has $12, then he can purchase 12/3.75 gallons. This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12)

about 3.2 gallons. (3.2, 12)

Answer:

45/8 or 5 5/8

Step-by-step explanation:

2 1/4. 2 times 4 is 8 plus 1 is 9 (9 over 4 (9/4)). 2 1/2. 2 times 2 is 4 plus one is 5. (5 over 8 (5/2)). 9/4 x 5/2. 9 times 5 is 45, 4 times 2 is 8.  you get the improper fraction 45/8. 45 simplified is 5 5/8. hope i helped.

Answer:

45/8 or 5 5/8

Step-by-step explanation:

When multiplying fractions, it ALWAYS so much easier to make them into improper fractions (for me at least). When doing this, multiply the denominator to the whole number and add the numerator and keep the denominator the same. So, for 2 1/4, you could use the equation 2(4) + 1 = x/4. You should get 9/4. Doing this for the other mixed fraction, you get 5/2.

Multiplying fractions is pretty straightforward after that. You don't have to change the denominators to match each other like you do when adding, instead you just multiply straight across. Multiply both of the numerators and then the denominators.

                                      Numerators: 9 x 5 = 45

                                      Denominators: 4 x 2 = 8

So, you get 45/8. If you're wanting a mixed number fraction, just divide 45 by 8. 8 goes into 40 5 times, and you get a left over number 5. Therefore, as a mixed fraction you get 5 5/8.

I don't know how you wanted me to show my work, but I tried the best I could to explain.

Answer:

C

Step-by-step explanation:

Okay so on Saturday there is a 30% sale plus she comes early so +10% and that makes 40% off.

10% of 400=40

multiply by 4 to get 40%, 40*4=40%

40%=160

400-160=240

Hope this helps

400 x 0.30 = 120

400 - 120 = 280

280 x 0.10 = 28

280 - 28 = 252

So 252 is you answer.
