Step-by-step explanation:
School guidelines require that there must be at least 2 chaperones for every 25 students going on a school trip. How many chaperones must there be for 82 students? A. 6 chaperones B. 41 chaperones C. 7chaperones D 3 chaperones
Answer:
A. 6 chaperones
Step-by-step explanation:
Since it's 2 chaperones per 25 students you would need to see how many times 25 can fit into 82
82/25 = 3.28
You can round that number to 3
Then you'll multiply 3 by 2 to get your number of chaperones for the school trip
3 x 2 = 6
There's still students left but not enough for there to be another chaperone so the answer is 6
How many 1 fourths are in 3 fourths?
Answer:
12
Step-by-step explanation:
This question means 3/(1/4). The rule for division of fractions is invert the denominator and multiply. 3/(1/4) = 3 * 4 = 12. Another way to think of it is to imagine you have 3 pies each divided into quarters.

Given the points P(2, –6) and R(8, 3), what is the component form of Vector P R?
⟨6, -3⟩
⟨10, -3⟩
⟨6, 9⟩
⟨10, 9⟩
Answer:
C
Step-by-step explanation:
The component form of vector PR is ⟨6, 9⟩.
How to determine the component form of vector PRTo find the component form of vector PR, we need to subtract the coordinates of point P from the coordinates of point R.
The x-component of the vector is obtained by subtracting the x-coordinate of point P from the x-coordinate of point R:
x-component = 8 - 2 = 6
The y-component of the vector is obtained by subtracting the y-coordinate of point P from the y-coordinate of point R:
y-component = 3 - (-6) = 3 + 6 = 9
Therefore, the component form of vector PR is ⟨6, 9⟩.

Natalie found a tennis ball outside a tennis court. She picked up the ball and threw it over the 12-foot fence into the court. The height of the ball, h, and time t seconds is given by the equations h(t) = -16t^2 + 18t +5. Will she make it iver the fence?
Answer:
Natalie cannot make it over the fence.
Step-by-step explanation:
After reading the statement, we must demostrate if the following inequation is possible, that is:
[tex]-16\cdot t^{2}+18\cdot t+5 \ge 12[/tex]
After some algebraic handling we find this equivalent expression:
[tex]16\cdot t^{2}-18\cdot t +7\le 0[/tex] (1)
The polynomial is factorized by the Quadratic Formula:
[tex]\left(t-0.563-i\,0.348)\cdot (t-0.563+i\,0.348)\le 0[/tex]
Since all roots are complex, we conclude that Natalie cannot make it over the fence.

Answer:
15
Step-by-step explanation:
Answer:
x=15
Step-by-step explanation:
Substutting in q(x) makes 3=4/5x-9
Add 9 to both sides to get 12=4/5x
Divide both sides by 4/5 and get 15=x
Thus, x=15
Which equation matches the graph y=-1x+3 , y=1x, y1x+3, y=-1x can you guys tell me which equation matches the graph with explanation
Answer:
y = 1.x + 3
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Since, y-intercept and x-intercepts are equal,
Let the given line passes through (0, 3) and (-3, 0),
Slope of the line (m) = [tex]\frac{3-0}{0+3}[/tex] = 1
y-intercept of the line 'b' = 3
Equation of the line will be,
y = 1.x + 3

a. 4x+x^3
b. 4x^4
c. 4x^3
d. (4x)^3
Answer:
f(g(x)) = 4x³
Hence, option C is true.
Step-by-step explanation:
Given
[tex]f(x) = 4x[/tex][tex]g\left(x\right)\:=\:x^3[/tex]Determine:
f(g(x)) = ?
solving the f(g(x))
f(g(x)) = f(x³)
= 4x³
Therefore,
f(g(x)) = 4x³
Hence, option C is true.

Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form
Answer:
y=2(x+3.5)^2+0.50
Step-by-step explanation:
we have
y=(x+3)^2+(x+4)^2
y=x^2+6x+9+x^2+8x+16
y=2x+14x+25
rewrite now in vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
y-25=2x^2+14x
Factor the leading coefficient
y-25=2(x^2+7x)
Complete the square. Remember to balance the equation by adding the same constants to each side
y-25+24.50=2(x^2+7x+3.5^2)
y-0.50-2(x^2+7x+12.25)
Rewrite as perfect squares
y-0.50=2(x+3.5)^2
y=2(x+3.5)^2+0.50
the vertex is the point (-3.5,0.50)
therefore the answer is
y=2(x+3.5)^2+0.50

How much will a group of 12 students save by choosing the science center?
Answer:
147
Step-by-step explanation:
If they go to the science center it will cost 3 people 36.75 cents so for 12 people it would be 36.75*4=147( I think let me know if I am wrong).

Percy's Pizzeria made 4 pizzas with pepperoni and 59 pizzas without pepperoni. What is the ratio of the number of pizzas with pepperoni to the number of pizzas without pepperoni? I had got 15/59 i wanna know if it is correct.
Answer:
4 : 59
Step-by-step explanation:
Close. But good try
So what is "ratio?"
Well seems like you got 15/59 i think you meant 15:59 right? ratio has a : in it.
But, you see there is only 4 pizzas with pepperoni in it so actually it should be
4 : 59
Good attempt anyways Trying is always better than nothing.
Find the slope of a line that passes through the points (2,3) and (4,1)
Answer:
The slope is -1
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
use y2-y1/x2-x1=m to find slope so if you plug both of the points in you would get 1-3/4-2=-2/2 and that would equal -1
