he is incorrect. you first have to find the least common denominator and that is 6. so then you would have 3/6- 2/6. that would equal 1/6.

Answers

Answer:

Three ppl, Twelve dogs

Step-by-step explanation

x=hoomans

y=doggos

x+y=15

2x+4y=54

x=15-y

2(15-y)+4y=54

30-2y+4y=54

2y=24

y=12

so that means there are 12 doggos

and since x=15-y, which is 15-12, which is 3,

A recipe for sparkling grape juice calls for
1/2
quarts of sparkling water and 3/4
quarts of grape juice

a. How much sparkling water would you need to mix with 9 quarts of grape juice?

b. How much grape juice would you need to mix with 15/4
quarts of sparkling water?

c. How much sparkling water would you need to make 100 quarts of punch?

d. How much grape juice would you need to make 100 quarts of punch?

Answers

A) 3/4 is equal to 0.75. 1/2 is equal to 0.5. You need to find out how many parts of the grape juice you have. So you take your 9 quarts and divide it by 0.75. That equals 12. So for the 9 quarts you need, you will add 12 parts of the 3/4. Now you need to add 12 1/2s as well. So 1/2 (or 0.5) multiplied by 12 is 6. So your answer would be 6 quarts

Answer:. A.) 6 quarts

B.) 45/8 quarts

C. 40 quarts sparkling water and 60 quarts of grape juice.

Once you get the basic ratio which is the amount of sparkling water is 2/3 the amount of grape juice, you can use that to set up as n equation for the next two questions.

Step-by-step explanation:

15/4 = 2x/3

Multiply both sides by the reciprocal:

3/2(15/4 = 3/2(2x/3)

45/8 = x

That is 5 5/8 quarts when simplified.

15/4 is 3 3/4 quarts

2 parts sparkling water to 3 parts grape juice is another useful ratio. Using that, 2x + 3x= 100 we can calculate

5x = 100

x 20. 2(20)=40 and 3(20)= 60

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to S(3, 4) and continues to T(3, −1). The total length of the walking trail is ___
units. (Input whole numbers only.)
HELPP ME PLSS

Answers

Answer:

Length from R(-2, 4) to S(3, 4) is sqrt((3 - (-2))^2 + (4 - 4)^2) = sqrt(5)^2 = 5 units

Length from S(3, 4) to T(3, -1) is sqrt((3 - 3)^2 + (-1 - 4)^2) = sqrt(-5)^2 = 5 units

Therefore, total length = 5 + 5 = 10 units.

A factory produced toy cars at a rate of 400 cars per hour. If 12 cars are defective each hour, what percent of the toys are defective?

Answers

Answer:

3% are defective

Step-by-step explanation:

400 cars are 100%

12 cars are x %

so x=12*100/400= 12/4=3 %

change/original times 100
change = 400-12
388/400(original)times 100=97
