Answer: Check out the filled out diagram below.

===================================================

Explanation:

To get the percentage, we divide the actual number by the total surveyed. This produces the decimal form of the percentage. Don't forget to move the decimal point 2 spots to the right to convert to the percentage.

For the first row, we have 480 people out of 1500 who said the personal computer was the most important invention.

So, 480/1500 = 0.32 = 32% of the people surveyed say the personal computer was the most important invention.

The fourth row will be handled the same way:

150/1500 = 0.10 = 10%

-------------

To go from a percentage to the actual number, we'll multiply the decimal form of the percentage by the number surveyed.

26% chose pacemaker, so 0.26*1500 = 390 people chose this item. Notice that 390/1500 = 0.26 = 26%

For the the third row, we have 0.18*1500 = 270 people who chose wireless communication as the most important.

-------------

To deal with the last row labeled "other", you'll need to keep in mind that percentages always add up to 100% as that's the highest it can go in many practical situations.

The percentages we calculated so far were: 32%, 26%, 18%, 10%

Those percentages add to: 32%+26%+18%+10% = 86%

The missing item must be 14% since 100% - 86% = 14%

Therefore, 14% of the 1500 people surveyed picked "other".

14% of 1500 = 0.14*1500 = 210 will go in the "actual number" column for this bottom row. Notice that 210/1500 = 0.14 = 14%

Also, notice that all the values in the "actual number" column add up to 1500

480+390+270+150+210 = 1500

This helps confirm our answers.

Liam has $250. Then, he and his classmates bought a present for their teacher, evenly splitting the $p cost among the 24 of them
Semenov [28]

Answer: The required expression will be

\frac{6000-p}{24}

Step-by-step explanation:

Since we have given that

Amount that Liam has = $250

Amount that he and his classmates spent on  present for their teacher =$p

Number of students in which $p will split = 24

According to question,

Amount that left to Liam is given by

250-\frac{p}{24}\\\\=\frac{6000-p}{24}

Hence, the required expression will be

\frac{6000-p}{24}

100 is 1/10 of what?
lawyer [7]

\boxed{ \ 100 \ is \ \frac{1}{10} \ of \ 1,000 \ }  

<h3>Further explanation  </h3>

The question can be rewritten to \boxed{ \ 100 \ is \ \frac{1}{10} \ of \ M \ }  

This case about equations with one variable. We have to solve this calculation to obtain the value of M. Our task is to isolate the variable M alone at the end of the process on one side of the equation until the variable will be equal to a value on the opposing side.  

Let's arrange it into an equation, i.e., \boxed{ \ 100 \ = \ \frac{1}{10} \times \ M \ }  

Turn this equation over so that the position of variable M is on the left side.  

\boxed{ \ M \times \frac{1}{10} = 100 \ }  

Both sides are multiplied by 10 to isolate M on the left side. The fraction are eliminated.  

\boxed{ \ M \times \frac{1}{10} \times 10 = 100 \times 10 \ }  

M = 1,000  

Therefore, we have calculated the number that was asked.  

Hence \boxed{ \ 100 \ is \ \frac{1}{10} \ of \ 1,000 \ }  

<u>Note:  </u>

The significant thing to carry out is how to manipulate both sides of the equation with the algebraic properties of equality such as:  

  • Adding  
  • Subtracting  
  • Multiplying, and/or  
  • Dividing both sides of the equation with a similar number

And the commutative property of multiplication, i.e., \boxed{ \ a \times b = b \times a \ }

The Calef family likes to paddle along the Susquehanna River.
xxTIMURxx [149]

<u><em>Answers:</em></u>

a. \frac{14}{3}=4.667 miles/day

b. 14 miles

<u><em>Explanation:</em></u>

<u>Part a:</u>

We are given that they paddled a total distance of 14 miles for 3 days. To get the distance paddled each day, we will divide the total paddled distance by the number of days

<u>This is done as follows:</u>

Distance paddled each day = \frac{14}{3}=4.667 miles/day

<u>Part b:</u>

<u>Now, we are given that:</u>

<u>i. They went half their daily distance:</u>

Daily distance = \frac{1}{2}*\frac{14}{3}=\frac{7}{3} miles/day

<u>ii. They extended the trip twice as many days</u>

Number of days = 2 × 3 = 6 days

The total distance paddled will be equivalent to the product of the distance paddled each day and the total number of days

<u>This means that:</u>

Total distance = \frac{7}{3}*6=14 miles

Hope this helps :)
