The number 18 is which percent of 15

Answers

Answer 1

Answer: The number 18 is a 120% of the number 15. That is because when you divide the two numbers you get 1.2. Then you multiply this number by a hundred to see what the percentage number is and you get 120 which means that 18 is a 120% of the number 15. Similarly, if you had for example 7, you would divide 7 by 15 and multiply and see that it's just under 50%. This is the basic formula for calculating percentage.

NEED HELP FAST PLEASE URGENT!!!!( the James family went out to eat and their total bill was $110. Since the service was great, they will leave a 20% tip. How much money should the family leave for tip? Answer is in money format and should include the dollar sign in front of the solution)

Answers

The family should leave $22

All we have to do is multiple 110 by 0.20 to get the answer.

If we multiple the two numbers, we get the number 22, so the James family should leave a $22 tip.

By the by, if we combine the two numbers, we get 132, meaning that the James family will spend $132 in total.

PLEASE HELPA group of students were surveyed to find out if they like bike riding and/or roller skating as a hobby. The results of the survey are shown below:

80 students like bike riding
20 students like bike riding but do not like skating
90 students like skating
40 students do not like bike riding

Make a two-way table to represent the data and use the table to answer the following questions.

Part A: What percentage of the total students surveyed like both bike riding and skating? Show your work.

Part B: What is the probability that a student who does not like bike riding also does not like skating?

Answers

A. The percentage of the total students surveyed like both bike riding and skating is 73.91%

B. The probability that a student who does not like bike riding also does not like skating is 0.261

Calculation of the percentage & probability:

Since

80 students like bike riding

20 students like bike riding but do not like skating

90 students like skating

40 students do not like bike riding

So,

a. The percentage should be

$= (80 + 90)/ = (80 + 20 + 90 + 40)\n\n= 170 / 230$

= 73.91%

b. The probability is

$= (20 + 40) / 230\n\= 60/ 230$

= 0.261

An expression is shown below. What is the product of the two factors ?

Answers

Answer: The required product is $x^2.$

Step-by-step explanation: We are given to find the product of the following two factors.

$P=(x^(4)/(3))(x^(2)/(3)).$

We will be using the following property of exponents:

$a^x* a^y=a^(x+y).$

We have

$P\n\n=(x^(4)/(3))(x^(2)/(3))\n\n=x^(4+2)/(3)\n\n=x^(6)/(3)\n\n=x^2.$

Thus, the required product is $x^2.$

Simplify the expression....
you have...
$( x^{ (4)/(3) } )( x^{ (2)/(3) } )$
simplifying it...
$x^(2)$
The product of the two factors....
Thus, your answer.
