The admission fee at an amusement park is $15.50 for children and $20.00 for adults. One day 217 people entered the park and the total admissions fees collected was $3.782
Define your variables as
"C" = # of children
"a" = # of adults
Write a system of equations to represent this information solve the system to find out how many children and how many adults came to the amusement park that day.
Answer:
Children = 124
Adults = 93
Step-by-step explanation:
x = children
y = adults
x + y = 217
x = 217 - y
15.50x + 20y = 3782
15.50 (217-y) + 20y = 3782
3363.50 - 15.50y + 20y = 3782
4.5y = 3782 - 3363:50
y = 418.50/4.5
y = 93
x + 93 = 217
x = 217 - 93
x = 124

A bag of apples cost $3.56. It cost $0.62 less than a bag of peaches. Ramses bought two bags at apples and a bag of peaches. He paid with a ten dollar bill. How much change does Ramses get
Answer: Ramses gets no change, in fact, he still owes money.
Step-by-step explanation: If one bag of apples costs $3.56 two bags will cost $7.12. If a bag of apples costs $0.62 less than a bag of peaches a bag of peaches costs $4.18 ($3.56 + $0.62). $3.56 + $3.56 + $4.18 = $11.30
$11.30 > $10.00
Ramses still owes $1.30
The highest common factor (HCF) of two numbers is 6.
The lowest common multiple (LCM) of the same numbers is 60
What are the two numbers?
Please explain every step
Answer:
12 and 30
Step-by-step explanation:
HCF = 6 = 2×3 means they both have in common a factor of 2 and a factor of 3, but at least one of the numbers has no more than one of each of these factors.LCM= 60=2²×3×5 means That the combined product of their factors counting only once the ones they have in common is 60.so they could be 2×2×3 = 12 and 2×3×5 = 30

Write an equation in Slope-Intercept Form using the table below.
Answer:
y = x + 46
Step-by-step explanation:
When writing an equation of a line, keep in mind that you always need the following information in order to determine the linear equation in slope-intercept form, y = mx + b:
1. 2 sets of ordered pairs (x, y)
2. Slope (m)
3. Y-intercept (b)
First, choose two pairs of coordinates to use for solving the slope of the line:
Let (x1, y1) = (0, 46)
(x2, y2) = (1, 47)
User the following formula for slope
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
Plug in the values of the coordinates into the formula:[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{47 - 46}{1 - 0} = \frac{1}{1} = 1[/tex]
Therefore, the slope (m) = 1.
Next, we need the y-intercept, (b). The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The y-coordinate of the point (0, 46) is the y-intercept. Therefore, b = 46.
Given the slope, m = 1, and y-intercept, b = 46, the linear equation in slope-intercept form is:
y = x + 46

A salesperson works 40 hours per week at a job where has two options for being paid. Option A is an hourly wage of 23$. Option B is a commission rate of 10% on weekly sales. How much does need to sell this week to earn the same amount with the two options
Answer:
$9200
Step-by-step explanation:
Since he works 40 hours a week and would make $23 for every hour with option A, we just multiply 40 by 23
40 x 23 = 920
This means 10% of the sales will need to equal to 920
Let x = sales
We multiply x by 0.1 to get 920
0.1x = 920
Divide both sides by 0.1
0.1x/0.1 = 920/0.1
x = 9200

Select all of the points which satisfy the linear inequality below.
-2x + 3y > 4
Answer:
x < − 2 + 3 y/ 2 linear inequality for x
y > 4/3 + 2x/3 linear inequality for y
Step-by-step explanation:
The point which satisfies the linear inequality is (-1,5) so option (C) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given inequality,
-2x + 3y > 4
Put (-1,5) into the above inequality,
-2(-1) + 3(5) > 4
2 + 15 > 4
17 > 4 (True) thus (-1,5) will satisfy the inequality.
The rest points are not satisfying the inequality.
Hence " The point which satisfies the linear inequality is (-1,5)".

Find the measure of the indicated angle in each triangle, to the nearest degree.
Answer:
Y = 98
C = 104.8
Step-by-step explanation:
All triangle are 180 degrees
A.
17 + 65 = 82
180 - 82 = 98
B.
73 + 2.2 = 75.2
180 - 75.2 = 104.8
