A) 3 2/3 - 1 5/12 we’ll convert to 12ths by multiplying the numerator and denominator of the first mixed number by 4.
3 8/12 - 1 5/12 = 2 3/12 = 2 1/4

b) 3 3/10 - 1 4/5 we’ll convert to 10ths by multiplying the numerator and denominator of the second mixed number by two.

3 3/10 - 1 8/10
Now we need to borrow from the three wholes to create more tenths
2 13/10 - 1 8/10 = 1 5/10 = 1 1/2

Or you can convert the first one to 33/10, and the second one to 9/5, which becomes 18/10.
33/10 - 18/10 = 15/10 = 1 1/2
Do whichever one makes more sense to your brain.

c) 4 5/9 - 3 1/2 we will convert both to 18ths.
4 10/18 - 3 9/18 = 1 1/18

d) 7 5/6 - 2 1/4 we will convert both to 12ths.
7 10/12 - 2 3/12 = 5 7/12

Please let me know if you have questions on these.

Answer:

(a)2 1/4

(b)1 1/2

(c)1 1/18

(d)5 7/12

Step-by-step explanation:

(a) 11/3 - 17/12 = 44/12 - 17/12 = 27/12 = 9/4 = 2 1/4

(b) 33/10 - 18/10 = 15/10 = 3/2 = 1 1/2

(c) 41/9 - 7/2 = 82/18 - 63/18 = 19/18 = 1 1/18

(d) 47/6 - 9/4 = 94/12 - 27/12 = 67/12 = 5 7/12

Hope it helped :)

Water flows through a pipe at a rate of 91 fluid ounces every 2.5 weeks. Express this rate of flow in cups per hour. Round your
Ulleksa [173]

Answer:

Step-by-step explanation:

First, we convert:

  • ounces to cups
  • weeks to hours

Result of conversion:

  • 91 fluid ounces = 11.375 cups  (1 cup = 8 ounces)
  • 2.5 weeks = 420 hours (1 week = 168 hours)

To get the rate, we must divide the number of cups by number of hours

  11.375 cups / 420 hours = 0.027 cups per hour = 0.03 cups per hour (approximated)

Hope that helps!

The number of rows in an auditorium can be represented by the function f(x) = 80x. The number of seats in each row can be repres
rusak2 [61]

Answer:

h(x) = 80x^2 + 560x

Step-by-step explanation:

To find the function h(x), that represents the total number of seats, we just need to multiply the functions f(x) (number of rows) and g(x) (number of seats per row):

h(x) = f(x) * g(x)

h(x) = 80x * (x+7)

h(x) = 80x*x + 80x*7

h(x) = 80x^2 + 560x

So the function that represents the total number of seats is:

h(x) = 80x^2 + 560x
