The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wrap costs $1.00 and the chicken wrap costs $1.50. Today they made $135.50 from the 117 wraps sold. How many of the wraps sold were vegetarian?
Answer:
Number of vegetarian wraps = 80
Number of chicken wraps = 37
Step-by-step explanation:
Let
Number of vegetarian wraps = x
Number of chicken wraps = y
x + y = 117 (1)
x + 1.5y = 135.50 (2)
Subtract (1) from (2) to eliminate x
1.50y - y = 135.50 - 117
0.50y = 18.50
y = 18.50/0.50
y = 37
Substitute y = 37 into (1)
x + y = 117 (1)
x + 37 = 117
x = 117 - 37
x = 80
Number of vegetarian wraps = 80
Number of chicken wraps = 37
A hiking trail rises 6 feet for every horizontal change of 100 feet. What is the slope of the hiking trail?
Given:
A hiking trail rises 6 feet for every horizontal change of 100 feet.
To find:
The slope of the hiking trail.
Solution:
We have,
Rise = 6 ft
Run = 100 ft
We know that
[tex]Slope=\dfrac{Rise}{Run}[/tex]
[tex]Slope=\dfrac{6}{100}[/tex]
[tex]Slope=0.06[/tex]
Therefore, the slope of the hiking trail is 0.06.
The slope of the hiking trail is equal to 0.06.
Given the following data:
Vertical distance (rise) = 6 feetHorizontal distance (running) = 100 feetTo find the slope of the hiking trail, we would use the following formula:
Slope is the ratio of the vertical distance measured to the horizontal distance measured.
Mathematically, the slope of a hiking trail is given by the formula:
[tex]Slope = \frac{Rise}{Running}[/tex]
Where:
V is the rising vertical distance of an object.H is the horizontal distance an object runs through.Substituting the given parameters into the formula, we have;
[tex]Slope = \frac{6}{100}[/tex]
Slope = 0.06

The equation of line L is 2x+y=3
Line M is parallel to line L and passes through
(1,−6)
Work out the equation of line M.
Give your answer in the form
y=ax+b
(3 marks)
Answer:
y = -2x - 4
Step-by-step explanation:
We transform the line equation of L:
2x + y = 3 --(-2x)--> f(x) = y = -2x + 3
We now know that L intersects the y-axis at 3 and it has a slope of -2.
In order to construct a parallel line M, it needs to have an identical slope to L.
All we need to do now is to move one step from the given point (1,-6) towards 0 with the predetermined slope of -2, resulting in the point (0,-4).
Since we know slope and intersection with the y-axis (0,-4), we can construct the line equation:
f(x) = y = -2x - 4 for line M.

Answer:
Slope=10 Y=15
Step-by-step explanation:
Goes up by 10
Starts at 0,15
The slope of an equation is 10 and the y-intercept is 15. Therefore, option B is the correct answer.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, the equation y= 10x + 15 represents a gym that charges.
By comparing y=10x+15 with y=mx+c, we get
Slope (m)=10 and y-intercept (c)=15
Therefore, option B is the correct answer.

A store manager wants to determine how much to pay her employees. The number of hours the employees work is x, and the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation 10y-30x=20 . The business owner states that the employees should be paid a wage given by the equation 6y+30x=60. If the two equations were added then simplified to determine hourly wage, y, how much would the employees be paid?
Answer:
The employees will work for 1 hour, will earn $5 per hour and will be paid $5
Step-by-step explanation:
System of Equations
The number of hours the employees work is x.
And the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation
10y-30x=20
The business owner states that the employees should be paid a wage given by the equation
6y+30x=60
Adding both equations we have:
16y = 80
Dividing by 16:
y = 80/16 = 5
Substituting into the first equation:
10*5-30x=20
Operating and simplifying:
50-30x=20
50 - 20 = 30x
30x = 30
x = 30/30 = 1
Thus, the employees will work for 1 hour, will earn $5 per hour and will be paid $5

How do I solve the triangles ?
Answer:
I'm so sorry I only found the area of the first triangle with the measurements 11, 10 and 17
I'll show you how to find the area
Step-by-step explanation:
The formula for a triangle is base x height divided by 1/2
For the first triangle the base is 11 and the height is 10
base(11) x height(10) = 110 then divide 110 by 1/2 = 55
so the area of the first triangle is 55.
Sorry again this is only the area of the first triangle.

Answer:
x² + 9x + 14 can be factored as (x+2)(x+7)
Step-by-step explanation:
The general form is ax² + bx + c. If a=1, then you can start looking for two numbers that multiplied give c and added give b.
14 = 2*7
and
9 = 2+7
hence the easy factorization
(x+2)(x+7)
Keep in mind that it only works if a=1.
Answer:
