Answer:

2 2/19

Step-by-step explanation:

5 cases in 2 3/8 hours

The unit rate of cases per hour is calculated by dividing the number of cases by the number of hours.

5/(2 3/8) = 5/(19/8) = 5 * 8/19 = 40/19 = 2 2/19

Evaluate 1/3 m- 1- 1/2 n when m=21 and n=12

liq [111]

Answer:

Step-by-step explanation:

First we have to identify 1/3 m. We know that m is 21 and 1/3 of 21 is 7.

Then we find 1/2 on n which we know is 12 so 1/2 of 12 is 6.

Then we subtract. 7-1 is 6 and 6-6 is 0

Hope this helped!!! :D

The current cost of gourmet coffee Is $14 per pound At the corner market the cost has increased 10% Per year over the past few y

KonstantinChe [14]

Answer:

$11.57

Step-by-step explanation:

Let's call the price of the coffee two years ago by X.

The price increased 10% per year (that is, the price is multiplied by 1+0.1=1.1) over two years, so the current price is:

X * 1.10 * 1.10 = X * 1.21

If the current price is $14, we have that:

X * 1.21 = 14

X = 14/1.21 = 11.57

The price of the coffee two years ago was $11.57

The LCM of two numbers is 36 their GCD is 3 one of the number is 9 find the other number

Aleks04 [339]

Answer:

Step-by-step explanation:

The LCM of 9 and x = 36

The GCD is 3, that means the number has to be divisible by 3 as well.

We can look at all the factors of 36, and see which numbers fit the description

36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

1: Does not have a GCD of 3

2: Does not have a GCD of 3

3: Has a GCD of 9, but LCM is 3, not 36

4: Does not have a GCD of 3

6: Has a GCD of 3, but LCM is 18, not 36

9: Number is given

12: Has GCD of 3, and LCM is 36

18: Has GCD of 9

36: Has GCD of 9

The only number that works is 12, with a GCD of 3, and an LCM of 36
