Answer:
188
Step-by-step explanation:
Find the total of everything he is using:
1 1/2 + 1/4 + 1/4 = 2 total cups.
For every two cups of trail mix he uses 1/4 cup of pretzels.
15 cups/ 2 cups = 7.5
7.5 x 1/4 cup of pretzels = 1 7/8 cups of pretzels.
Answer:
A: initial value: $750; rare of change: $60
B: y = 60t + 750
Step-by-step explanation:
Initial value = value when he started ( in 2000) =$ 750
Each year he add a constants to that value
'y' will be the amount he get after t years a amount increase each year
y = 750 + at
In 2010 his free = 1350
t = 2010 - 2000 = 10 year
y = 1350
y = 750 + at
1350 = 750 + 10 a
600 = 10a
a = 60
y = 750 + 60t ( his fee as a function of time)
In slope form: y = 60t + 750
He increases he fee by $60 a year.
Answer:
321.
Step-by-step explanation:
First, divide 2250 by 7 to see how many times 7 can go in. You should get 321 and 3 as your remainder. To put it into mixed number format, it would put 321 as your whole number and your remainder divided by 7. It would be 321 3/7. Hope this helps :)
