A barista averages making 16 coffees per hour. At this rate, how many hours will it take until she's made 1,200 coffees?

Answers

Answer 1
Answer: 16 times x=1200 or 
16x=1200
divide both sides by 16
1200/16
so we  simplify 1200/16 by factoring out the ones (4/8=1/2 times 4/4 since 4/4=1)
1200=3*2*2*2*2*5*5
16=2*2*2*2*1
so we notice that there are four 2's in both so those are the 'ones' so cross them off and get
3*5*5/1 or 75/1 or 75 hours 
Answer 2
Answer: 75 hours
1200 coffees/16 coffees= 75 hours

A recipe for sparkling grape juice 1 1/2 quarts of sparkling water and 3/4 of grape juice. How much sparkling water woild you need to mix with 9 quarts of grape juice. How much grape juice would you need to mix with 15/4 quarts of sparkling water?

Answers

According to the recipe the ratio of sparkling water to grape juice = 1 1/2 : 3/4.

Let us convert 1 1/2 into improper fraction and that is 3/2.

Now, 3/2: 3/4 or 3/2 ÷ 3/4 = 3/2 × 4/3 = 2/1 or 2:1.

Therefore, sparkling water quantity is two times of the quantity of grape juice.

Now, we need to find the number of quarts of sparkling water need to mix in 9 quarts of grape juice.


Since, sparkling water quantity is two times of the quantity of grape juice.

Therefore, we need 2 × 9 = 18 quarts of sparkling water to mix in 9 quarts of grape juice.


And now we need to find the number of quarts of grape juice would we need to mix with 15/4 quarts of sparkling water.

Therefore, we need 1/2 × 15/4 = 15/8 quarts of grape juice to mix with 15/4 quarts of sparkling water.



Answer:

a)x = 18\,qt, b)y = 1\,(7)/(8)\,qt

Step-by-step explanation:

a) The amount of sparkling water needed is determined by simple rule of three:

x = (9\,qt)/((3)/(4)\,qt)* (3)/(2)\,qt

x = 12* (3)/(2)\,qt

x = 18\,qt

b) The amount of grape juice needed is found by simple rule of three:

y = ((15)/(4)\,qt)/((3)/(2)\,qt ) * (3)/(4)\,qt

y = (30)/(12)* (3)/(4)\,qt

y = (90)/(48)\,qt

y = (15)/(8)\,qt

y = 1\,(7)/(8)\,qt

C=25. S=a. B=4c-s2. What would b equal to

Answers

Answer: B = 100 - a^2

Solution:

Step 1: Substitute all the values that are given in the equation

that would be C = 25 and S = a


Step 2: when substituted the equation would be

B = 4 (25) - (a)^2

B = 100 - a^2 Would be the answer

Note: if there was a numerical value to s then the answer would be a number but since s=a so the answer has variable too.
