Jake buys a car for $1500 and sells it for $1800. What is Jake’s percentage profit?

Westkost [7]

step by step explanation:

Jake brought a car = 1500rs

Jake sell the car = 1800

profit = sp-cp

so profit = 1800-1500 = 300

profit percent = gain/cp×100

profit percent = 300/1500×100

profit percent = 20% (double zero are cancel and 300 divided by 15)

This is super easy here is the steps to find the answer:

1. First the base of the cone
Pii*radius*radius

3.14*10*10 which equals 314

2. Now multiply 314 and 14 and you should get 4396

3. Now divide by 3 and you should get 1465.33

If the least value of n is 5, which inequality best shows all the possible values of n?

ZanzabumX [31]

Answer:

First option

Step-by-step explanation:

The inequality says greater than or equal to 5. Which means n is greater than or equal to (≥) 5.

It's not the second option because less than or equal to means that n is less than or equal 5, which doesn't check out since 5 is the smallest value of n.

It's not the third option since it says that 5 is greater than n, when we know that one of n's values is 5.

It's not the fourth option since it says that that n is greater than 5, when we know again that one of the values of n is 5.

Your answer is the first option "n ≥ 5."

Hope this helps.
