What is the Unit price of 20 tickets for $14.00 ?
chubhunter [2.5K]

Answer: 1 ticket = 70 cents.

Step-by-step explanation:

If you get 20 tickets for 14.00, then we have to divide 14 by 20.

14 ÷ 20 = 0.7, or 70 cents. Because of this, each ticket will cost 70 cents.

Christopher estimates it will take him half an hour to complete his math homework. He is able to complete it in 25 minutes. What
marin [14]

Answer:

The percent error in his estimate is<u> 16.67%</u>.

Step-by-step explanation:

Given:

Christopher estimates it will take him half an hour to complete his math homework.

He is able to complete it in 25 minutes.

Now, to find the percent error  in his estimate.

Time estimates of completing homework = 30 minutes.

Time actual taken to complete homework = 25 minutes.

Error in estimate = Time estimates of completing homework - Time actual taken to complete homework.

Error in estimate = 30 minutes - 25 minutes.

Error in estimate = 5 minutes.

Now, to get the percent error:

Percent\ error =\frac{Error\ in\ estimate}{Time\ estimates\ of\ completing\ homework} \times 100.

Percent\ error=\frac{5}{30} \times 100

Percent\ error=\frac{500}{30}

Percent\ error=16.67\%.

Therefore, the percent error in his estimate is 16.67%.

Can someone help me with this question????
frutty [35]

Answer:

Hi! I think I got the answer, it is a tricky one! The answer I got was C) 1029.

Step-by-step explanation:

1. It is good to first know that 40%more means 1.4 (some number). So, if n is 40% more than the sum of the other three numbers: n= 1.4* (<em>l +m+p)</em> .

2. Also note that: <em>n+l+m+p= </em>1764; so, <em>n = 1764-l-m-p.</em>

3. Since we have two expressions for n, we can equate them to each other. Giving, 1.4* (<em>l +m+p) =1764-l-m-p . </em>Simplifying we get 2.4 (<em>l +m+p)</em>=1764.

4. <em>l +m+p =1764/2=735.</em>

5. 1764-735=1029

Hope that helps! Feel free to message back if there are any questions!

How much water can this container hold
harina [27]

Answer:

972π cm³

Step-by-step explanation:

Okay so this container is a sphere, so you're going to want to use the volume of a sphere equation V = (4/3) * π * r³. In this case, you've got the diameter (d = 18), so divide by 2 to get r = 9.

So now you have all the variables you need to solve. Substituting those values into the volume equation, you get:

V = (4/3) * π * 9³ = 972π cm³.
