Answer:

It will take 25 minutes to reach first in line.        

Step-by-step explanation:

Data given in the question:

Distance between Jackson and his friend = 40 feet

Rate at which the line is moving = 16 feet per 10 minute

Thus, time taken by Jackson to reach the position his friend is standing is given by:

\text{Time taken = }\displaystyle\frac{\text{Distance}}{Rate}

\text{Time taken} = \displaystyle\frac{40\text{ feet}}{16\text{ feet per 10 minute}}

= \displaystyle\frac{40\times 10}{16} = 25\text{ minutes}

Proportion used can be written as

Time:10::40:16

The average of 10 numbers is −10. If the sum of 6 of them is 100, what is the average of the other 4? 20pts
Allushta [10]

Answer:

The sum of the other 4 numbers is -200

Step-by-step explanation:

Let

x------> the sum of 6 numbers

y-----> the sum of the other 4 numbers

we know that

\frac{x+y}{10}=-10 -----> equation A

x=100

substitute the value of x in the equation A

\frac{100+y}{10}=-10

\frac{100}{10}+\frac{y}{10}=-10

10+\frac{y}{10}=-10

\frac{y}{10}=-10-10

\frac{y}{10}=-20

y=-20*10=-200

She paid 26.35 for something that would usually be 31 dollars. what percent discount did she get
Alex17521 [72]

<u>Answer:</u>

She paid 26.35 for something that would usually be 31 dollars. The percentage discount she got is 15%

<u>Solution:</u>

A lady paid $26.35 for something that is usually $31, so she got a discount for the product.

Now, we have been asked to find out how much percentage discount she got.

To do that we first have to check how many dollars she got off the product.

To do so we have to subtract the discounted price from the initial price.

Therefore we get:

31 - 26.35 = 4.65

To find the percentage discount we need to do the following

\begin{array}{l}{=\frac{4.65}{31} \times 100} \\\\ {=0.15 \times 100 = 15}\end{array}

Therefore she got a discount of 15%

Help with 7 please. Please show work and explain
jolli1 [7]

Answer:

Blue: 13/100 = 0.13 = 13%

Purple: 130/100=1.3=130%

Step-by-step explanation:

The picture shows 100 cubes in a grid that's 10 by 10. This means the shaded amount is a number out of 100. The first is 13 out of 100 which converts to 0.13 and 13%. The second has all the cubes shaded which means 100/100 which is 1 or 100% plus the last has 30 cubes out of 100 which converts to 0.30 or 30%. Together this makes 130/100 or 1.30 or 130%.
