Stephen spends 10% of his salary on food, 15% of it on transportation, and saves the remaining 2000. what is his salary?
Ber [7]

Answer:

His salary is $2666.68

Step-by-step explanation:

First add the percent of the costs.       10% + 15% = 25%

Then subtract 25% from 100% to find the percentage that 2,000 is of the total salary.                                                           100% - 25% = 75%

$2,000 is 75% of the total salary. Divide 2,000 by three to find the amount of money 25% of the salary is. ( 75% is 3/4 of 100)                                                         2,000 divided by 3 = $666.67

25% of the salary is $666.67

Multiple that by 4 and you get the total salary.

666.67•4= $2666.68

Are you sure those were all the correct numbers because that was not a very nice number at the end there lol but that answer is correct with the numbers you gave me.

lora16 [44]

Answer:

The scale factor is \frac{3}{2}

Step-by-step explanation:

Yes the figures are similar to each other. The ratio of their linear measurements is in uniform ration

The ration of radius of large cylinder (R) to that of the smaller cylinder (r) is

\frac{18}{12} \\\frac{3}{2}

Like wise the ration of height of large cylinder (H) to that of the smaller cylinder (h) is

\frac{30}{20} \\\frac{3}{2}

The scale factor is \frac{3}{2}
