Your gym teacher needs to put 96 students into 12 equal groups. Complete the equation to show which operation to use and how many students will be in each group. Then complete the sentence to explain your reasoning.
Answer:
8
Step-by-step explanation:
We will use the math operation division to find the answer. Division takes a total and divides it into equal amounts. We have a total of 96 and need equal amounts in to each of the 12 groups.
96/12=8 students per group
To divide 96 students into 12 equal groups, you perform a division operation. Using 96 / 12, we find that there are eight students per group.
To determine how many students will be in each of the 12 equal groups, you use division. The total number of students which is 96 will be divided by the number of groups which is 12. Therefore, the equation you need is 96 / 12 = eight students per group.
This division operation is similar to when five students working on a group assignment divide it into five equal parts. Each of the students completes one part. In our scenario, instead of five parts, we are dividing 96 students into 12 parts, hence creating equal groups for the gym class activity.

Answer: 8.50 dollars
The result is positive, so this is a gain (instead of a loss)
====================================
Explanation:
Focus on the "stock JKL" row only when it comes to the percentages we'll use. We need to convert them to decimal form
15% ---> 0.15
65% ---> 0.65
20% ---> 0.20
I just moved the decimal point over 2 spots, or you can divide by 100 (eg: 15% = 15/100 = 0.15)
Multiply each of these values by their corresponding loss or gain. Use negative numbers for losses
15% chance of losing $25 ---> 0.15*(-25) = -3.75
65% chance of winning $5 ---> 0.65*(5) = 3.25
20% chance of winning $45 ---> 0.20*(45) = 9
Now add up those results: -3.75+3.25+9 = 8.50

Which point on the unit circle corresponds to −4π/3 ?
(1/2, −3√/2)
(-3√/2, 1/2)
(-1/2, 3√/2)
(3√/2, −1/2)
Answer:
[tex]\left(-\frac{1}{2},\frac{\sqrt{3}}{2}\right)[/tex]
Step-by-step explanation:
We know that coordinate of any point on unit circle is given by
[tex]\left(\cos\left(\theta\right),\sin\left(\theta\right)\right)[/tex]
Given that [tex]\theta=-\frac{4\pi}{3}[/tex]
So we just need to plug the value of given angle [tex]\theta=-\frac{4\pi}{3}[/tex] into above formula:
[tex]\left(\cos\left(\theta\right),\sin\left(\theta\right)\right)[/tex]
[tex]=\left(\cos\left(-\frac{4\pi}{3}\right),\sin\left(-\frac{4\pi}{3}\right)\right)[/tex]
[tex]=\left(\cos\left(2\pi-\frac{4\pi}{3}\right),\sin\left(2\pi-\frac{4\pi}{3}\right)\right)[/tex]
[tex]=\left(\cos\left(\frac{2\pi}{3}\right),\sin\left(\frac{2\pi}{3}\right)\right)[/tex]
[tex]=\left(-\frac{1}{2},\frac{\sqrt{3}}{2}\right)[/tex]
Hence choice (3) is correct.

Chapman’s brickyard sells bricks and blocks. A brick costs $0.38 and a block costs $1.56. The brickyard filled a $24.80 order, which contained 28 items
a. Write a system of equations that can be used to find the number of bricks and blocks in the order.
b. How many blocks were in the order?
Answer:
(a) A system of equations:
[tex]0.38x+1.56y = 24.80[/tex]
[tex]x+y = 28[/tex]
(b) Number of blocks were in the order is, 12
Step-by-step explanation:
(a)
Let x represents the number of bricks and y represents the number of blocks.
As per the given statement:
A bricks costs $ 0.38 and a block costs $1.56.
Total bricks costs = 0.38x and total block costs = 1.56y
The brickyard filled $24.80 order.
⇒ [tex]0.38x+1.56y = 24.80[/tex] ......[1]
Since, it contained 28 items.
⇒[tex]x+y = 28[/tex] ....[2]
Multiply equation [2] both sides by 0.38 we have;
[tex]0.38(x+y) = 0.38 \times 28[/tex]
Using distributive property: [tex]a\cdot (b+c) = a\cdot b + a\cdot c[/tex]
0.38x +0.38 y = 10.64 ......[3]
Subtract equation [3] from [1] to get x eliminated ;
[tex]0.38x+1.56y -0.38x -0.38y= 24.80 - 10.64[/tex]
Combine like terms;
1.18y =14.16
Divide both sides by 1.18 we have;
[tex]\frac{1.18y}{1.18} = \frac{14.16}{1.18}[/tex]
Simplify:
[tex]y = 12[/tex]
Substitutes this y value in equation [2] to solve for x;
x + 12= 28
Subtract 12 from both sides we get;
x +12-12 =28-12
Simplify:
x = 16
Therefore, a system of equations that can be used to find the number of bricks and the number of blocks in the order:
[tex]0.38x+1.56y = 24.80[/tex]
[tex]x+y = 28[/tex]
(b)
The number of blocks are in order(y), is 12.

Find the coordinates of the midpoint of the segment. MN with endpoints M (6, 14) and N( −4, −4)
The midpoint of line segment MN with endpoints M (6, 14) and N (-4, -4) can be calculated using the formula: ( (x1 + x2) / 2, (y1 + y2) / 2 ) which gives the midpoint coordinates as (1, 5).
Explanation:In order to find the midpoint of a line segment in a 2-dimensional space, you can use the midpoint formula: ( (x1 + x2) / 2, (y1 + y2) / 2 ). For the given endpoints M (6, 14) and N(-4, -4), substitute the respective values into the formula:
X-Midpoint = (6 + -4) / 2 = 1
Y-Midpoint = (14 + -4) / 2 = 5
Thus, the coordinates of the midpoint of segment MN are (1, 5).

A jar contains 5 green, 3 black, and 2 red marbles. Brandi draws a marble from the jar and then puts it back. She then draws another marble. What is the probability that Brandi draws
2 green marbles_____? 2 red marbles_______? A black and green marble_____? A green and a red marble______?
Answer:
The answers are as follows:
2 Green = 25%
2 Red = 4%
1 Black 1 Green = 15%
1 Green 1 Red = 10%
Step-by-step explanation:
In order to find any of these, we first have to find the probability of pulling any of them individually. To find that, we simply divide the number of marbles by the total in the jar.
Green = 5/10 = 50%
Black = 3/10 = 30%
Red = 2/10 = 20%
Now to find any combination, simply multiply the percentages together. For instance, for 1 black and 1 green, multiply those percentages together.
Black * Green
30% * 50% = 15%
You can do this for any number of combinations

A. [tex]F(x)=2x^{9} -4x^{2} +4[/tex]Step-by-step explanation:
First of all, par and odd functions have their graphic particularities.
Specificially, if the grade of the polynomial is pair, then the function has a symmetric graph, the curve will have a returning point, like the parabola. On the other and, if the grade of the polynomial is odd, then the graph of the function won't have an symmetry like pair ones, and it won't have a returning points like parabolas
So, in this case, the raph doesn't have a returning point like a parabola or an U movement, that means possible answers are A and B.
Choice B cannot be the answer because the negative sign in the first term indicates a reflection accros the vertical axis, and the graph is showing an original function.
Therefore, the right answer is A. [tex]F(x)=2x^{9} -4x^{2} +4[/tex]

An evil supervillian has launched a drone from his/her submarine. The drone's height, in meters above sea level, as a function of time, t , in seconds, is given by h ( t ) = − 4.9t^2 + 133t + 152
What is the maximum height? Round your answer to three decimal places.
Answer:
the maximum height is 1054.500 meters
Step-by-step explanation:
h ( t ) = − 4.9t^2 + 133t + 152
a= -4.9 , b= 133 and c= 152
To find maximum height , we find vertex
[tex]x= \frac{-b}{2a}=\frac{-133}{2(-4.9)}= 13.5714 [/tex]
Now plug in 13.5714 for 't' in h(t)
[tex]h(t) =-4.9t^2 + 133t + 152[/tex]
[tex]h(t)=-4.9( 13.5714)^2 + 133( 13.5714)+ 152=1054.500[/tex]
the maximum height = 1054.500 meters
The maximum height of the drone is approximately 1347.174 meters.
To find the maximum height of the drone, we need to find the vertex of the quadratic function h(t) = -4.9t^2 + 133t + 152. The vertex of a quadratic function in the form f(t) = at^2 + bt + c is given by the coordinates (t, f(t)) where t = -b/2a and f(t) is the maximum value.
Plugging in the values from our function, we have t = -133/(2*(-4.9)) = 13.67347. Substituting this value of t back into the function, we get h(13.67347) = -4.9*(13.67347)^2 + 133*(13.67347) + 152 = 1347.174 meters. Therefore, the maximum height of the drone is approximately 1347.174 meters.

Solve the system of linear equations by substituting. Check your solution
4# y=5x-7
-3x-2y=-12

6# -7x-2y=-13
x-2y=-13
Answer:
4. x=2 y=3
5. x=-3, y=-6
6. x=0, y=6.5
Step-by-step explanation:
A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. To use substitution, we substitute a equivalent expression in for a variable and solve for the remaining variable. We then substitute again to find the other variable.
y=5x-7 & -3x-2y=-12
We will input for y, the expression 5x-7 into -3x-2y=-12. We will then isolate x to solve for it using inverse operations.
-3x-2(5x-7)=-12
-3x-10x+14=-12
-13x+14=-12
-13x+14-14=-12-14
-13x=-26
x=2
We substitute back in now to solve for y. y=5(x)-7=5(2)-7=10=7=3
-4x+y=6 & -5x-y=21
We will input for y, the expression 6+4x into -5x-y=21. We will then isolate x to solve for it using inverse operations.
-5x-(4x+6)=21
-5x-4x-6=21
-9x-6=21
-9x-6+6=21+6
-9x=27
x=-3
We substitute back in now to solve for y. y=4(x)+6=4(-3)+6=-12+6=-6
-7x-2y=-13 & x-2y=-13
We will input for x, the expression 2y-13 into -7x-2y=-13. We will then isolate y to solve for it using inverse operations.
-7(2y-13)-2y=-13
-7(2y)+-7(-13)-2y=-13
-14y+91-2y=-13
-16y+91=-13
-16y+91-91=-13-91
-16y=-104
y=6.5
We substitute back in now to solve for x. x=2y-13=2(6.5)-13=13-13=0.
