Answer:
= 29.82 yards/second
Step-by-step explanation:
The speed is given in the problem. We just need to convert its units. The multiplicative identity (that is, 1) may be used to change the units without changing the value. (note: do you know what the additive identity is?)
61 miles per hour
(61 miles) / (1 hour)
(61 miles)/(1 hour)*1
((61 miles)/(1 hour))*((5280 feet)/(1 mile))
((61 miles)/(1 hour))*((5280 feet)/(1 mile))*((1 yard)/(3 feet))*((1 hour)/(60 minutes))*((1 minute)/(60 seconds))
note: miles, feet, hours, minutes cancel out; leaving yards per second
(61/1)*(5280/1)*(1/3)*(1/60)*(1/60) yards/second (note: I write that way to paste into Excel)
Answer: The greatest number of cups of yogurt MOnica can buy is 14.
Step-by-step explanation:
If she need to buy a gallon of milk then it means that $2.50 will be deducted from the money .
Use the the inequality to solve for how many cups of yogurt Monica can buy
1.20x + 2.50 ≤ 20
-2.50 2.50
1.20x ≤ 17.5
x≤14.5833...
which means the greatest number of cups of yogurt Monica can buy is 14.
M = 9
7 times 9 equals 63 and then you add 8 it equals 71.
7x9=63+8=71
