Bailey made risotto using a recipe that called for 223 cups of liquid. Bailey added 23 cup of liquid to the risotto every 10 minutes. Drag and drop to complete the equation to find how many times Bailey added 23 cup of liquid.

Answers

Answer:

4 times

Step-by-step explanation:

Given that :

Cups of liquid required = 2 2/3

Fraction of liquid cup added per 10 minutes = 2/3

The number of times 2/3 cups of liquid is added :

Total cups of liquid required / amount of liquid added at a time

2 2/3 ÷ 2/3

8/3 ÷ 2/3

8/3 * 3/2

24 / 6

= 4 times

Emelia is booking a flight to San Francisco. The airline charges 5270 for the ticket and 16% for taxes and fees. How much will Emelia pay for her flight?
(show your work)

Answers

ANSWER:
$6113.20


EXPLANATION:
There is two ways to make an expression to solve this which is
y = 1.16x
or
y = x + 0.16x

Here is the explanation for the first expression, it is more thorough:

The airline makes her pay x amount in dollars for the ticket alone. Then, the airline charges an additional 16% of that x amount. Just a policy they’ve required.
Therefore:
y = x + 0.16x

• x is the ticket price
• 0.16x is 16% of that ticket price

Plug x with the initial charge amount:
y = 5270 + 0.16(5270)
y = 6113.20



10% of 5270 = $527
5% of 5270 = $263.50
1% of 5270 = $52.70
6% of 5270= $316.20
16% of 5270 = $843.20

$843.20 + $5270 = $6113.20

The opposite of angle r is 45

the adjacent of angle r is 28
