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

kali runs 12 laps around a track each day. Each lap around the track is 400 meters. How many days will it take Kali to run the total of 12 kilometers?

Answers

Answer: 2.5 days

Step-by-step explanation:

First we should convert 12 kilometers to meters so that is 12000 meter. Now we know that she runs 12 laps each day and each lap is 400 meters so lets find out how much she runs in one day. 12 laps*400meters= 4800 meters

So an easy way to figure out how many days is to divide 4800 meters she runs each day from the total 12,000 meters she needs to run so 12,000/400=2.5.

It will take kali a total of 2.5 ( two and a half days) to run 12000 meters or 12 kilometers

Use Substitution to solve the following System of Equations.
y = 2x - 4
y= 12 +3

Answers

Answer:

x = 9.5

this should be the right answer if the same one you had to solve.

Step-by-step explanation:

y = 2x - 4

y = 12 + 3                             combine them

2x - 4 = 12 + 3

    +4         +4                   The 4's cancel each other out

2x = 12 + 7                     Add then divide

 2x = 19

  2x = 19

  ----   ----

   19   19

 x = 9.5

. Jumbo bought 5 books, each with a whole-number price.
The mean price of the books was $10. The median price was $8.
The most expensive book cost $15 and the cheapest cost $6.
What are the possible prices for the other books?

Answers

Mean is average. Multiply total books by the mean to find the total cost:

5x 10 = $50 total.

Subtract the highest and lowest prices to find the total of the remaining 3 books.

50 - 15-6 = 29

The median price was 8, this is the middle number, subtract 8 from 29 to get the cost of the last 2 books:

29-8 =21

Now you need a price lower than the median but higher than the lowest cost so that has to be 7

Subtract 7 from 21 to get the cost of the last book 21-7 = 14

The price of the remaining books is $7 and $14

two vertical poles of heights 12 inches and 22 inches are separated by a horizontal distance of 24 inches. what will be the distance between the tops of these poles?

Answers

Answer: 26 in.

Step-by-step explanation:

Given

Heights of Poles are [tex]12\ in., 22\ in.[/tex]

distance between them is [tex]x=24\ in.[/tex]

the difference in heights of the pole is [tex]y=22-12=10\ in.[/tex]

From the figure, using Pythagoras theorem, distance L is given by  

[tex]\Rightarrow L^2=y^2+x^2\\\Rightarrow L^2=10^2+24^2\\\Rightarrow L^2=100+576=676\\\Rightarrow L=\sqrt{676}=26\ in.[/tex]

The distance between tops is 26 in.

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
