Answer:
The number of students in each van = 14
The number of students in each bus = 43
Step-by-step explanation:
Let the number of students that can fill a van be v.
Let the number of students that can fill a bus be b.
The senior class at High School A rented and filled 13 vans and 9 buses with 569 students.
13 vans will have (13v) students
9 buses will have (9b) students
13v + 9b = 569
High School B rented and filled 14 vans and 3 buses with 325 students
14 vans will have (14v) students.
3 buses will have (3b) students.
14v + 3b = 325
Combining these two simultaneous equations
13v + 9b = 569
14v + 3b = 325
Solving simultaneously,
v = 14 students.
b = 43 students.

Brooke solved the equation below: 6r = 72 6r − 6 = 72 − 6 r = 66 Is Brooke’s solution correct? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation.
Answer:
see below
Step-by-step explanation:
6r = 72
We need to divide each side by 6, not subtract 6 from each side
6r/6 = 72/6
r = 12
Answer:
Brooke's solution is incorrect
Divide both sides by 6
r=12
Step-by-step explanation:
The equation is:
6r=72
Brooke solved the equation like so:
6r-6=72-6
r=66
Brooke's solution is incorrect. She subtracted 6 from both sides of the equation.
Here is how the equation should be solved:
6r=72
We want to solve for r, so we have to get r by itself. 6 and r are being multiplied (6*r=6r). The inverse of multiplication is division, so we must divide both sides by 6 (not subtract 6 from both sides).
6r/6=72/6
r=72/6
r=12
Brooke's solution is incorrect. She subtracted 6 instead of dividing by 6. The correct solution is r=12.

One number is seven less than a second number. Five times the first is 2 more than 6 times the second. Find the numbers. The value of the first number is _____.
Answer:
[tex]\Large \boxed{\sf \ \ 40 \ \ }[/tex]
Step-by-step explanation:
Hello,
Let's not a and b the two numbers.
One number is seven less than a second number.
(1) b = a - 7
Five times the first is 2 more than 6 times the second.
(2) 5a = 2 + 6b
(2)+5*(1) gives
5a + 5b = 2 + 6b + 5a - 35
b = 35 - 2 = 33
a = 40
The value of the first number is [tex]\large \boxed{\sf \ \ 40 \ \ }[/tex]

What is the range of the function for the given domain? y = 2x − 5 D: {-2, 0, 2, 4}
Answer:
Range of Function : { - 9, - 5, - 1, 4 }
Step-by-step explanation:
We know that y = 2x - 5 provided the domain ( x - values ) { - 2, 0, 2, 4 }. Let us substitute each element in this set of domain as x in the equation "y = 2x - 5" as to solve for the y - values, otherwise known as the range of the function.
{ - 2, 0, 2, 4 }
y = 2( - 2 ) - 5 = - 9,
y = 2( 0 ) - 5 = - 5,
y = 2( 2 ) - 5 = - 1,
y = 2( 4 ) - 5 = 4
We have the set of y - values as { - 9, - 5, - 1, 4 }. This is the range of our function.
The formula for calculating simple interest is I = prt. Which is the equivalent equation solved for r? StartFraction I Over p t EndFraction = r StartFraction p t Over I EndFraction = r I minus p t = r I + p t = r
Answer: r = I/pt
Step-by-step explanation:
Interest divided by the principal × time gives the rate. It's usually expressed as a percentage per year.
The equivalent equation for r is r=I/pt which is option a.
What is equation?Equation is relationship between two or more variables that are expressed in equal to form. Equation of two variables look like ax+by=c. It is of many types like linear equation, quadratic equation, cubic equation, etc.
How to find equation?We have been given an equation I=prt and we have to find the equivalent equation which is solved for r.
I=prt
In this p is principal, r is rate of interest and t is time period.
Divide both sides by pt.
I/pt=prt/pt
I/pt=r
Hence the equation equivalent to I=prt is r=I/pt which is option a.

WILL MARK BRAINLIEST Give a real world example of an equation which the constant of proportionality is 15. What would the graph look like?
Answer:
Let's say someone is selling lemonade at a lemonade stand. The more cups of lemonade this person sells, the more money they get. If 1 cup= $1, then he would get $2 for 2 cups.
Step-by-step explanation:
The price of the lemonade cup and the lemonade cup are a constant of proportionality. They are proportional to each other. The more lemonade you sell, the more money you get.
The graph would be a straight diagonal line. The y would be the money, and the x would be the amount of lemonade sold. Since they are the same and proportional, they would go in a straight line.
Which are the roots of the quadratic function f(q) = q? - 125? Select two options.
Oq=515
Oq=-575
Oq=3/5
Oq=-375
Oq=25/5
Answer:
A and C
Step-by-step explanation:
The roots of the quadratic function f(q) = q² - 125 are q = 5 and q = -5.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The quadratic function f(q) = q² - 125 can be factored as (q - 5)(q + 5).
Now,
To find the roots, we set the function equal to zero and solve for q:
So,
q² - 125 = 0
(q - 5)(q + 5) = 0
q - 5 = 0 or q + 5 = 0
q = 5 or q = -5
Therefore,
The roots of the quadratic function f(q) = q² - 125 are q = 5 and q = -5.

Write an equation in slope-intercept form for the line that satisfies the following condition.
passes through (29,8), perpendicular to the graph of y= 5x +17.
Select one:
a. y = 385x + 1
b.y = -132 +385
c. Y = 12 +385
d.y= -132 + (-13)
Answer:
y = - x + 69
Step-by-step explanation:
Given the following :
Point on graph : (29, 8)
Equation of line ; y= 5x +17.
From the equation slope of line = 5
Intercept = 17
Slope of perpendicular line = - 1/5 ( negative reciprocal)
Using the equation :
y - y1 = m(x - x1)
From the Point given:
x1 = 29, y1 = 8
y - 8 = (- 1/5)(x - 29)
y - 8 = -1/5x + 29/5
y = -1/5x + 29/5 + 8
Multiply through by 5
y = - x + 29 +40
y = - x + 69
A company is building a new park in the shape of a circle with a 25 ft diameter. Portions of the new park will be covered with grass. A diagram of the park is given below, with the shaded region representing the areas that will be covered in grass. Use 3.14 for. Note: image is not drawn to scale. The area of the regions covered by grass is approximately sq ft.
Answer: The area of the regions covered by grass is approximately 313.375 sq ft.
Step-by-step explanation:
Given: A company is building a new park in the shape of a circle with a 25 ft diameter.
Then radius = [tex]\dfrac{25}{2}=12.5\ ft[/tex]
Required area = Area of circle - Area of rectangle + Area of triangle
Formula: Area of circle = [tex]\pi r^2[/tex]
Area of rectangle = length x width
Area of triangle = 0.5 x base x height
Area of circle = [tex](3.14)(12.5)^2=490.625\ \text{ft}^2[/tex]
Area of rectangle = 20 ft x 10ft = 200 ft²
Area of triangle = 0.5 x 7 x 6.5 = 22.75 ft²
Required area = 490.625 -200+22.75 = 313.375 ft²
Hence, The area of the regions covered by grass is approximately 313.375 sq ft.

A) One
B) Two
C) An infinite number
D) No solution
Answer: The correct answer is: [D]: " No solution " .
______________________________________
Step-by-step explanation:
We are given the following system of equations:
2x − 3y = 10 ;
-4x + 6y = -20 ;
_______________________________________
Let us take the second equation:
-4x + 6y = -20 ;
and multiply each side by "-1 " ; to get rid of the "negative numbers" ; and to rewrite the equation without the "negative numbers" :
- 1 * { - 4x + 6y } = -1 * (-20} ;
to get:
4x − 6y = -20 ;
Now, let us simply this equation further; by divide each side of the equation by "2" ;
(4x − 6y) / 2 = (-20) / 2 ;
→ [ (4x) / 2 ] − [ (6y) / 2 ] = -10 ;
to get: 2x − 3y = -10 ;
Then we have: 2x − 3y = 10 ;
Note: 10 ≠ -10 .
_______________________________________
So the answer is: [D]: " No solution."

Which of the following cross sections cannot be produced by slicing a right rectangular prism? A. pentagon B. circle C. rectangle D. trapezoid
Answer:
The answer is option B.
Step-by-step explanation:
Since it's a rectangular prism slicing will produce either a rectangle or trapezoid and not or a circle since it's round
Hope this helps you
Answer: B. Circle
Step-by-step explanation:
Since the base is a rectangle and the faces are rectangular, there is no way to slice the prism to get a a circle.
The trapezoid ? Maybe. A diagonal slice starting on a corner will create a quadrilateral with uneven sides.
Pentagon? Imagine starting on the top near a corner-- but not on the corner-- with a diagonal line, slicing down towards the opposite corner. You should be able to get an irregular pentagon.
A rectangle is easy!
No circles!
