Answer:
0.96%
Step-by-step explanation:
We are looking for the percent that represents "6 out of 625"
Divide to find the decimal answer:
6/625 means
6 ÷ 625
= 0.0096
Then multiply by 100 to change to a percent.
0.0096 × 100
= 0.96%
A certain pond has a minnow population of 20,000, and the population of minnows is increasing at a rate of 5% per year. The algae that the minnows eat is diminishing due to an excess amount of UV light, and the number of minnows it can support is shrinking by 750 each year. How is the population of minnows growing, and how is the supply of algae declining
Answer:
20000(.05)^x-750

At what point does the line given by the following equation cross the y-axis?
y = 6/9x+3
a. (0,3)
b. (3,0)
c. (0,-)
d. (-9/2,0)
Answer:
A
Step-by-step explanation:
In a slope-intercept equation, the format goes like this:
y = mx + bM = Slope
B = Y-intercept
In the equation, y = 6/9x + 3:
The slope is 6/9
The y-intercept is 3.
So what the question means by "cross the y-axis" is when the line on the graph is going through the y-intercept point.
Because the y-intercept is 3, the ordered pair would look like this:
(0, 3)
Note: The y-intercept is when the x-intercept has a value of 0 and the y-intercept is only on the y-axis, never the x-axis.
Therefore, the answer would be Option A. (0, 3)

Sharon brought $19.50 to the state fair. She bought a burger, a souvenir, and a pass. The burger was 1/3 as much as the souvenir, and the souvenir cost 1/2 the cost of the pass. Sharon had $2.00 left over after buying these items.
What was the cost of each item?
The cost of pass is $10.5, the cost of burger is $1.75, and the cost of souvenir is $5.25 if the Sharon brought $19.50 to the state fair.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the cost of the pass is $x
The souvenir cost 1/2 the cost of the pass, which is x/2
The burger was 1/3 as much as the souvenir, which is (1/3)(x/2) = x/6
x + x/2 + x/6 + 2 = 19.50
x = 21/2
x = $10.5
The cost of pass = $10.5
The cost of burger = $1.75
The cost of souvenir = $5.25
Thus, the cost of pass is $10.5, the cost of burger is $1.75, and the cost of souvenir is $5.25 if the Sharon brought $19.50 to the state fair.

3n - 2what is the area of a heptagon with an apothem of 15.5 and side length of 15
Answer:
813.75
Step-by-step explanation:
area of a regular polygon = side length × # of sides × apothem × 1/2
here side length = 15 , # of sides = 7 ( a heptagon has 7 sides ) and apothem = 15.5
so area = 15 × 7 × 15.5 × 1/2
==> multiply 15 by 7 by 15.5
area = 1627.5 × 1/2
==> divide 1627.5 by 2
area = 813.75

is perpendicular to y = -8x + 2
and contains the point (-4, 1).
Answer:
Step-by-step explanation:
Perpendicular lines will have negative inverse slopes of each other. In this case, the slope of the known line is -8. The negative of -8 or -(-8) is just +8. The inverse of +8 is +1/8.
Now we know the slope of the line perpendicular to y=-8x+2 and we are given the point (-4,1).
All linear lines have the form of y=mx+b and we know the slope.
y=1/8x+b
We plug in (-4,1) into the equation:
1=1/8 * -4 +
1=-1/2+b
b=3/2
We now have the b constant and can simply just write the equation:
y=1/8x+3/2

Find 3 consecutive positive integers such that the product of the larger 2 is equal to twice the second integer plus twice the sum of all 3 integers
Step-by-step explanation:
x, x+1, x+2 are the 3 consecutive positive integers.
(x+1)(x+2) = 2(x+1) + 2×(x+x+1+x+2)
x² + 3x + 2 = 2x + 2 + 2×(3x + 3)
x² + 3x + 2 = 2x + 2 + 6x + 6 = 8x + 8
x² - 5x - 6 = 0
we can solve this by finding the factoring.
that means we find a, b so that
(x - a)(x - b) = x² - 5x - 6 = 0
because then x = a and x = b are the 2 solutions of the quadratic equation.
we have
x² - ax - bx + ab = x² - (a+b)x + ab = x² - 5x - 6
a+b = 5
ab = -6
that means, either a or b must be 6 and the other -1.
so we get
(x - 6)(x + 1) = 0
x = 6
or
x = -1
since we are only looking for positive integers, the x = -1 solution is invalid, and we get only x = 6 as solution.
therefore the 3 consecutive positive integers are
6, 7, 8

Explain how to identify the restrictions on the variable when adding or
subtracting rational expressions.
Rational expressions are those that have fractional terms. We state restrictions because it may cause the equation to be undefined in some values of x. The most common restriction for rational expressions is N/0. This means any number divided by zero is undefined.
What is rational expressions and examples?A rational expression is nothing more than a fraction in which the numerator and/or the denominator are polynomials. Here are some examples of rational expressions.
To find the restrictions on a rational function, find the values of the variable that make the denominator equal 0.
