18 is 60% of what number

Answers

Answer 1

Answer: is means equal

of means multiplication

Soooo

$\sf{18 = (60)/(100) * x}$

And simplifying that

$\sf{18 * (100)/(60) = x}$

And simplifying that more:

$\sf{30 =x}$

So x=30

So the number you are looking for is 30

Answer 2

Answer: 18 is 60% of what number? 30 is your answer.
Let n be the number.

18 = 60% of n
18 = 0.6n
18/0.6 = n
30 = n

A sociologists was investigating the ages of grandparents of high school students. From a random sample of 10high school students, the sociologist collected data on the current ages, in years, of the students' maternal grandparents. A. One of the sociologist's research questions was about the mean difference in age without regard to which grandparent is older. The interval constructed in part (a) does not address such a question. Based on the sample of high school students, give the value of the point estimate for the mean difference in age that could be used to address the sociologist's question.

b. 32

Step-by-step explanation:

a. 12 + 4y

They gave us the value of "y" which is "5", and substitute that into the expression.

12 + 4y

12 + 4(5)

12 + 20

b. 4 (y + 3)

They gave us the value of "y" which is "5", and substitute that into the expression.

4 ( y + 3 )

4 ( 5 + 3)

The degree of the polynomial function is 6. The "fundamental theorem of algebra" tells you the number of roots is equal to the degree of the polynomial.

f(x) has 6 roots.

The mean age of five children is 8 years 4 months. When Amina joins, the mean age becomes 8 years 5 months. How old is Amina. With workings please.

Answers

Answer:8 5/12 - 8 3/4

101/12- 35/4 LCM 12 &4 is 12

101- 35/12= 66/12

=5 6/12

=5 1/2 years

Step-by-step explanation:

Final answer:

The question is about the calculation of Amina's age. From the information provided, Amina's age is calculated to be 9 years 4 months. The calculation is done by first obtaining the total age before and after Amina joins then finding the difference.

Explanation:

Firstly, we know the mean age of five children, before Amina joins, is 8 years 4 months. To get the total age of these children, we multiply the mean by the number of children. So, 8 years 4 months x 5 gives 41 years 8 months in total.

Next, Amina joins, increasing the number of children to six and the mean age becomes 8 years 5 months. To get the new total age, we multiply the new mean by the total number of children, so, 8 years 5 months x 6 gives 51 years.

So, the age of Amina is found by subtracting the initial total age before she joined from the new total age after she joined, which is, 51 years - 41 years 8 months = 9 years 4 months.

Thus, Amina's age is 9 years 4 months.

Two minutes after a diver enters the water, he has descended 52 feet After 5 minutes, he has descended 130 feet At what rate is the scuba diver descending

Answers

Answer:

26ft/minute

Step-by-step explanation:

The question asks to calculate the rate at with a scuba diver is descending.

Firstly, we should know that the rate at which the scuba diver is descending is calculated as the total amount of distance descended, divided by the total amount of time taken.

The total amount of distance descended is 52ft + 130ft = 182ft

The total amount of time taken is 5 + 2= 7 minutes

The rate of descending is thus 182ft/7min = 26ft/minute
