Answer:

  70, 140, 280, 350

Step-by-step explanation:

Obviously, it must have the factors 2, 5, 7 as a minimum, so the smallest value is 2×5×7 = 70.

Any of these primes can be added to the product. In increasing order, the smallest additional factors will be 2, 4, 5, 7, 8, 10, ...

So, the four smallest numbers with prime factors of 2, 5, and 7 are ...

  70 = 2·5·7

  140 = 2²·5·7

  280 = 2³·5·7

  350 = 2·5²·7

Find the percent of increase to the nearest whole from 12 to 20
ankoles [38]

Answer:

The answer is

<h2>67\%</h2>

Step-by-step explanation:

To find the percentage increase we use the formula

<h3>Percentage \:   change =  \frac{change}{original \:  \: quantity}  \times 100\%</h3>

From the question

The original value = 12

To find the change we subtract the smaller value from the larger one

That's

Change = 20 - 12 = 8

So the percentage increase is

<h3>\frac{8}{12}  \times 100 \%\\  =  \frac{2}{3}  \times 100\% \\  = 66.67\%</h3>

We have the final answer as

67\% to the nearest whole number

Hope this helps you
