The average of 5 numbers is 20. what is the sum of these same numbers?

1 answer:

4 0

Average = (A₁+A₂+A₃+A₄+A₅)/5. Since average = 20 (GIVEN), then:

20 = (A₁+A₂+A₃+A₄+A₅)/5

Or (A₁+A₂+A₃+A₄+A₅) = 20x5

(A₁+A₂+A₃+A₄+A₅) = 100

The ratio of students who prefer pineapple to students who prefer kiwi is 12 to 5. Which pair of equivalent ratios could be used

AlexFokin [52]

Answer:

105 students could prefer kiwi if there are 357 total students.

Step-by-step explanation:

Given:

The ratio of students who prefer pineapple to students who prefer kiwi is 12 to 5.

Now, to find number of students prefer kiwi if there are 357 total students.

Let the students prefer pineapple be $12x.$

And the students prefer kiwi be $5x.$

Total students = 357.

So, we set an equation to get the number of students who prefer kiwi.

According to question:

$12x+5x=357$

$17x=357$

Dividing both sides by 17 we get:

$x=21.$

Thus, students prefer kiwi are:

$5x$

$=5\times 21=105.$

Therefore, 105 students could prefer kiwi if there are 357 total students.

Choose the correct conic section to fit the equation.

yanalaym [24]

Answer:

Option A) Circle.

Step-by-step explanation:

We are given the equation:

$(x - 3)^2 + (y - 12)^2 = 25$

A general equation of the circle is of the form:

$(x-h)^2 + (y-k)^2 = r^2$

where (h,k) is the center of the circle and r is the radius of circle.

Comparing the two equations, we get,

$(h,k) = (3,12)\\r = \sqrt{25} = 5$

Thus, the given equation is equation of a circle centered at (3,12) and of radius 5 units.

The larger of two numbers is four more than the smaller. if the larger is x what is the smaller?

Lelu [443]

Answer:

x-4

Step-by-step explanation:

Since the larger of two numbers is four more than the smaller one, this means that there is a difference of 4 between the two numbers. In order to find the smaller of both numbers, you can obtain the smaller from the largest by subtracting 4.
