Answer:

15.8%

Step-by-step explanation:

The percent of the total population that are students may be computed by expressing the ratio of the number of students to the total population of people as a percentage.

Given that there are 9860 students and  the total population of people is 62400, the percent of the total population is students

= 9860/62400 * 100%

= 15.8%

A certain mixture of paint contains 5 parts white paint for every 4 parts blue paint. If a can of paint contains 75 ounces of wh
Len [333]

Answer:

60 ounces

Step-by-step explanation:

A certain mixture of paint contains 5 parts white paint for every 4 parts blue paint, that is, the white paint (w) to blue paint (b) ratio is 5:4. We can apply this ratio to different units such as ounces. This means that the mixture has 5 ounces of white paint to 4 ounces of blue paint. If a can of paint contains 75 ounces of white paint, the ounces of blue paint in the can are:

75 oz w × (4 oz b/5 oz w) = 60 oz b

The fourth term of a sequence is 108. Each term after the first is 3 times the previous term. Write an explicit expression that
marishachu [46]

Answer:

f(n)=4(3)^{n-1}

Step-by-step explanation:

Let the first term be x, then the terms of the sequence are:

x,3x,9x,27x,81x,....

Since the fourth term is 108, we have

27x=108

\implies x=4

Hence the sequence becomes:

4,12,36,108,324,....

The explicit expression for a geometric expression is given by:

f(n)=ar^{n-1}

where a=4 and r=3

The required formula is:

f(n)=4(3)^{n-1}

On a coordinate plane, a line goes through (negative 4, 0) and (4, negative 4). A point is at (2, 3).
Valentin [98]

9514 1404 393

Answer:

  (b)  x +2y = 8

Step-by-step explanation:

The only offered line that includes the given point is ...

  x +2y = 8

__

We can check the other choices:

  x + 2y = 2 +2(3) = 2+6 = 8 . . . matches B (not A)

  2x +y = 2(2) +3 = 4+3 = 7 . . . . not a choice

_____

<em>Getting there from scratch</em>

The standard form equation for a line can be written from ...

  (y2 -y1)x -(x2 -x1)y = constant

  (-4 -0)x -(4 -(-4))y = constant . . . . using the given points (-4, 0) and (4, -4)

  -4x -8y = constant

For standard form, we need the leading coefficient to be positive, and we need common factors removed. We can get there by dividing by -4.

  x +2y = constant

The value of the constant will be whatever it takes for the given point to lie on the line. For (x, y) = (2, 3) to be a solution, we must have ...

 x +2y = (2) +2(3) = constant = 8

The desired line has the equation ...

  x +2y = 8
