Sebastian swam laps every day in the community swimming pool. He swam an hour each day, 5 days each week, for 12 weeks. In
that time, he swam 1,800 laps. What was his average rate in laps per hour?
Answer:
0.25
Step-by-step explanation:
1,800 laps ÷ 12 weeks = 150 laps
150 laps ÷ 5 days each week = 30 laps per day
30 laps per day ÷ 120 hours per week = 0.25 per hour

Multiply.
31.2 x 10 x 3
Answer:
936
Step-by-step explanation:
You multiply 31.2 by 10, so you move the decimal one place to the right, so it's 312, And then, you multiply those numbers by 6 like 3, 1, and 2. For the ones digit 2 x 3 = 6, for the tens digit, 1 x 3 = 3, and for the hundreds digit, 3 x 3 = 9. Therefore, the answer is 936!

which graph shows the solution to the system of linear inequalities below?
y<-1/3x+1
y ≤ 2x-1
The graph that shows the solution set for the system of inequalities is graph C.
Which is the graph of the system of linear inequalities?
Here we have the system of linear inequalities:
[tex]y < (-1/3)*x + 1\\\\y \geq 2x- 1[/tex]
For the first one, we can see a line with a negative slope, and y is strictly smaller than that. So we will have a dashed line that goes down, and we need to shade the region below that line.
For the second inequality, we can see that y can be equal to or larger than the line, so this time we will use a solid line (because the points on the line are solutions). and we will shade above that line.
Also notice that this time the slope is positive, so this line goes upwards.
With that general description, we conclude that the correct option will be graph C.

There are 50 dogs signed up for a dog show. There are 36 more small dogs than large dogs. How many small dogs have signed up to compete?
There are 43 small dogs signed up in the competition
How to determine the number of small dogs?Represent the small dogs with x and the large dogs with y.
So, we have the following equations
x + y = 50
x = 36 + y
Make y the subject in x = 36 + y
y = x - 36
Substitute y = x - 36 in x + y = 50
x + x - 36 = 50
Evaluate the like terms
2x = 86
Divide both sides by 2
x = 43
Hence, there are 43 small dogs in the competition

Write an equation in slope-intercept form of the line that contains the point (-2, 2) and has the slope = -5.
Answer:
[tex]y=-5x-8[/tex]
Step-by-step explanation:
Given the following question:
To calculate the slope intercept of a line/point we need to use the formula for slope intercept, substitute, and solve for b.
Formula for slope intercept:
[tex]y=mx+b[/tex]
[tex]m=-5[/tex]
[tex]y=2[/tex]
[tex]x=-2[/tex]
[tex]2=-5(-2)+b[/tex]
Solve for b:
[tex]2=-5(-2)+b[/tex]
[tex]-5(-2)=10[/tex]
[tex]2=10+b[/tex]
[tex]10-10=0[/tex]
[tex]2-10=-8[/tex]
[tex]-8=b[/tex]
[tex]b=-8[/tex]
Substitute for the following:
[tex]y=mx+b[/tex]
[tex]b=-8[/tex]
[tex]m=-5[/tex]
[tex]y=-5x-8[/tex]
Your answer is "y = -5x - 8."

GEOMETRY Find the perimeter of the regular polygon. A regular polygon with three sides. The two sides are labeled 5 minus 2 x, and negative 4 x plus 9. The perimeter of the polygon is____units.
Answer:
19 units
Step-by-step explanation:
A regular polygon has equal-length sides. This fact can be used to solve for the value of x, and for the side length. Knowing the side length, we can find the perimeter.
__
side length5 -2x = 4x +9 . . . . . marked sides are the same length
-4 = 6x . . . . . add 2x -9
-2/3 = x . . . . . divide by 6
5 -2(-2/3) = 5 +4/3 = 6 1/3 . . . . length of one side
perimeterThe perimeter is the sum of the side lengths, or 3 times the length of one side.
P = 3s = 3(6 1/3)
P = 19 . . . . units
The perimeter of the polygon is 19 units.

What are the zeros of the function using the quadratic formula
By the quadratic formula, we find that the two zeroes of the quadratic function y = x² - 20 · x + 32 are x₁ = 10 + 2√17 and x₂ = 10 - 2√17, respectively.
How to find the zeroes of a second order polynomial
A value of x is a zero of a polynomial if and only if [tex]\sum\limits_{i=0}^{n} c_{i}\cdot x^{i} = 0[/tex], the quadratic formula for second order polynomials of the form a · x² + b · x + c = 0 is presented below:
[tex]x =\frac{-b \pm \sqrt{b^{2}-4\cdot a \cdot c}}{2\cdot a}[/tex]
If we know that a = 1, b = -20 and c = 32, then the roots of the second order polynomial are:
[tex]x = \frac{20 \pm \sqrt{(-20)^{2}-4\cdot (1)\cdot (32)}}{2\cdot (1)}[/tex]
[tex]x = 10 \pm 2\sqrt{17}[/tex]
By the quadratic formula, we find that the two zeroes of the quadratic function y = x² - 20 · x + 32 are x₁ = 10 + 2√17 and x₂ = 10 - 2√17, respectively.
