Explanation:

To find what is 30% of 150, we will need to write an equation. We will convert 30% into fraction form, then multiply 150 with the fraction. Once multiplied, we will get our result.

Solution:

  • 30% = 30/100
  • => 30/100 x 150
  • => (30/50 × 2) × 3 × 50
  • => 15/50 × 3 × 50
  • => 15 × 3
  • => 45

Final Answer:

30% of 150 is 45.

then multiply .3 and 150

150 x 0.3 = 45

An account earns simple interest. $1800 at 6.5% for 30 months Find the interest earned.
horrorfan [7]
Okay. The formula for simple interest is prt. You multiply the principal (initial amount) by the rate (percentage) by the time (months or years). $1,800 is the principal and 6.5% is the percentage rate. 1,800 * 6.5% (0.065) is 117. You earn $117 in interest annually. The time period is 30 months. There are 12 months in 1 year. Divide the amount of months by 12 to put it in a decimal. 30/12 is 2.5. Now, multiply 117 by 2.5 to find the total amount of interest earned. 117 * 2.5 is 292.5. There. The total amount of interest earned is $292.50.

3p - 2(p-4) = 7p + 6
Serggg [28]

For this case we must find the value of the variable "p" of the following equation:

3p-2 (p-4) = 7p + 6

We apply distributive property on the left side of the equation taking into account that +*-=-  and - * - = +:

3p-2p + 8 = 7p + 6

We add similar terms:

p + 8 = 7p + 6

We subtract 7p  from both sides of the equation:

p-7p + 8 = 6\\-6p + 8 = 6

We subtract 8 from both sides of the equation:

-6p = 6-8\\-6p = -2

We divide by -6 on both sides of the equation:

p = \frac {-2} {- 6}\\p = \frac {1} {3}

Answer:

p = \frac {1} {3}

A won a race at the local fair by running 10.5 miles in exactly 2 hours. At this constant​ rate, how long does it take the same
Luba_88 [7]

Answer:

The dog will run the 21-mile race in 4.04 hours

Step-by-step explanation:

The first thing we need to do is find out how far he ran the race at the local fair in 1 hour.

To do this, we can set up a simple relationship:

If he ran 10.5 miles in 2 hours,

He will run x miles in 1 hour

Cross multiplying, we have

x = (10.5 X 1)/2 = 5.25 miles in 1 hour.

We can now comfortably say that he runs at the rate of 5.2miles/hr

He now goes to the state fair race, which is 21 miles long.

if he runs at the rate of 5.2 miles in 1 hour,

He will run 21 miles in y hours

y = 21 / 5.2 = 4.04 hours

The dog will run the 21-mile race in 4.04 hours
