A school is going on a field trip to a museum. The ratio of men to women to children is 1:3:20 and there are 216 people on this trip. What is the difference between the number of children and adults?
Answer:The difference between the number of children and adults=153
Step-by-step explanation:
ratio of men to women to children is 1:3:20
Total RATIO = 1+ 3+ 20= 24
Number of men = ratio of men / Total ratio x Total Number of people on the trip =
= 1/24 x 216= 9 men
Number of women=ratio of women / Total ratio x Total Number of people on the trip = 3/ 24 x 216 = 3x 9= 27 women
Number of children=ratio of Children/ Total ratio x Total Number of people on the trip = 20/24 x 216= 20 x9 = 180 children
The difference between the number of children and adults will be 180 -27 = 153

Write the equation of the line that passes through the points (1, -6) and (8, 9). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
[tex]y-9 = \frac{15}{7} (x-8)[/tex]
Step-by-step explanation:
Point-slope form is represented by [tex]y-y_1 = m (x-x_1)[/tex]. To write an equation with it, we need the slope of the line and a point the line crosses through. We already have at least one point the line crosses through, so let's figure out the slope.
To find the slope, use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line crosses, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line crosses. So, using the x and y values of (1, -6) and (8, 9), substitute them into the formula and solve:
[tex]\frac{(9)-(-6)}{(8)-(1)} \\= \frac{9+6}{8-1} \\= \frac{15}{7}[/tex]
Thus, the slope is [tex]\frac{15}{7}[/tex].
2) Now, using the point-slope form of [tex]y-y_1 = m (x-x_1)[/tex], substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values in order to write an equation in point-slope form. The [tex]m[/tex] represents the slope, so substitute [tex]\frac{15}{7}[/tex] in its place. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point on the line. So, choose any one of the points given - either one is fine - and substitute its x and y values for [tex]x_1[/tex] and [tex]y_1[/tex]. (I chose (8,9)). This gives the following equation and answer:
[tex]y-9 = \frac{15}{7} (x-8)[/tex]

An online shopping club has 13000 members when it charges $7 per month for membership. For each $ monthly increase in membership fee, the club loses approximately 500 of its existing members. Write and simplify a function R to represent the monthly revenue received by the club when x represents the price increase.
Hint: Monthly revenue = # members•monthly fee
Just a answer with work will do, ill brainliest the best one.
Answer:
The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]
Step-by-step explanation:
Total members=13000
Membership charge per month=$7
Increase in Membership charge per month=$1
For each $1 monthly increase in membership fee, the club loses approximately=500 members
For 1 month, 1 dollar decrease is 500 × 1
For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]
The increase in membership fee is 7 + [tex]x[/tex]
After that,
Monthly revenue = Number of members × Monthly fee
Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]
[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

A female cheetah left her cubs to hunt for food. She sprinted 30 m away from her den in two seconds. Next, she turned around and traveled 10 meters back toward her den in three seconds. She suddenly stopped and listened intently for 1 second. Then, she traveled 40 meters away from her den in four seconds.
What is her average velocity in m/s?
Answer:
Step-by-step explanation:
total distance = 30+10+40 = 80 meters
time = 2+3+4 = 9 seconds
average velocity = 80/9 = 8 8/9 meters per second.
The equation y=9.50 +0.4 represents the line of best fit for the distance in feet) that Marcella traveled over time
(in seconds) based on several races she ran.
Based on this equation what is Marcella's average speed in feet per seconds?
Enter the answer as the correct value without units.
marking brainlist
Answer:
9.9 feet per second
Step-by-step explanation:
y=9.5+0.4
y=9.9
Marcella's average speed in feet per seconds is,
⇒ y = 9.54 feet
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The equation which represents the line of best fit for the distance in feet) that Marcella traveled over time (in seconds) based on several races she ran is,
⇒ y = 9.50x + 0.4
Hence, Marcella's average speed in feet per seconds is,
y = 9.50x + 0.4
Put x = 1;
y = 9.50 × 1 + 0.4
y = 9.50 + 0.4
y = 9.54 feet
Thus, Marcella's average speed in feet per seconds is,
⇒ y = 9.54 feet

Step-by-step explanation:
Vertical angles are equal. Set these equal to each other to solve. 7x-18 = 6x+ 7. Add 18 to both sides. 7x = 6x + 25. Subtract 6x from both sides. X=25

Answer: B -4
Step-by-step explanation:
Value of coefficient of the squared term in the parabola's equation = -4
Correct option is B.
What is parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.
Given,
Vertex of parabola (h,k) = (3, 5)
y = 6 for x = -1
Parabola opens horizontally left side
Vertex-form equation of parabola
x = a(y - k)² + h
-1 = a(6 - 5)² + 3
-1 = a(1) 3
a = -4
Hence, -4 is value of coefficient of the squared term in the parabola's equation.

Answer:
most likely asking for something like this
Step-by-step explanation:
Answer:
Read the step-by-step for the entire answer!!!
Step-by-step explanation:
Whenever you have situations like these you have to look at it from the perspective given.
If you are throwing a ball it's going to start at ground 0 where the child is, therefore the height of the child is how high off the ground the ball is at 0 seconds.
If it is thrown, and it is stuck in the tree for a few seconds, then that means on the graph you will see an incline of the graph, and then a stale line for a few seconds as the ball is stuck in the same height for a few seconds.
After the ball falls down, then so will the height of the ball.
t - a function of time, is always on the x-axis because time variables are usually on the x-axis of a graph.
I choose seconds as a measurement of time because in a realistic situation a ball will be in the air for seconds.
h - the height of the ball, will be on the y-axis of the graph because it is a dependent variable (i.e. the height of the ball is dependent on how long the ball is in the air for).
The image below is the graph.
