Answer:
9 and a half complete trays.
Step-by-step explanation:
A dozen is 12. Amy bakes 114 buns. Equation: 114 ÷ 12 = 9.5. Amy will have 9 and a half complete trays.
Saturday and Sunday: 8 1/4 hours + 6 1/4 hours = 33/4 + 25/4 = 58/4 = 29/2 hours = 14 1/2 hours
A total of 88 1/2 miles = 177/2 miles for both days.
If you would like to know how long does it take him to ride one mile on his bike, you can calculate this using the following steps:
88 1/2 miles ... 14 1/2 hours
1 mile ... x hours = ?
88 1/2 * x = 1 * 14 1/2
177/2 * x = 29/2 /*2
177 * x = 29 /177
x = 29/177 hours
x = 0.16 hours
Result: It takes him 0.16 hours to ride one mile on his bike.
Answer:
$2070.14
Step-by-step explanation:
Credit card terms vary, as do methods of computing interest and new balance. Here, we'll assume that no payment has been made (<em>in violation of the terms of the credit card</em>), and that the finance charge is only applied to the previous balance.
The finance charge is ...
$1853.68 × 0.249 ÷ 12 = $38.46 . . . . . . . the monthly rate is 0.249÷12
Then the new balance will be the sum of the previous balance, finance charge, and new transaction(s):
$1853.68 +38.46 + 178.00 = $2070.14
_____
<em>Comment on lack of payment</em>
Because no payment has been made, there may also be a late-payment charge added to the balance.
Answer:
1200
Explanation:
y represents the estimated population
t represents the number of years.
The equation that predicts the population after t years is given as:
Substitute t = 3/2 into the equation
The closest valuie to the value of y is 1200
