Answer:
C. 40
Step-by-step explanation:
Start with multiplying the 120 students who took the computing and networking courses with 1160 hours. 120 times 1160 = 139200
That means that 139200 hours of the 164800 hours are by the students who took computing and networking classes, so now we have to subtract.
164800 - 139200 = 25600
Now divide 25600 with 640, because 25600 is the hours for the business course. 25600/640 = 40
So there's 40 students

2x - 3y = 12
Answer:
y= -2/3x - 4
x= 3/2y + 6
Step-by-step explanation:
2x - 3y = 12 (plus 3y)
2x = 3y +12 (divide by 2)
x = 3/2y + 6
2x - 3y = 12 (minus 2x)
-3y = 2x + 12 (divide by -3)
y = -2/3x - 4

a. $761.60
b. The store bought the dishwasher for the price they are currently selling it at. They are receiving no profit when it is on sale.
Step-by-step explanation:
give brainliest pls
If 20% is the greatest possible markdown the store can give without losing money, then the price of the dishwasher is $761.60
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that the Sales price = $952
Markdown % = 20%
The Sales price = (100 - 20)% x $952
The Sales price = 80% x $952
The Sales price = $761.60
If 20% is the greatest possible markdown the store can give without losing money, then the price of the dishwasher is $761.60

An exterior angle equals the sun of the two opposite inside angles:

-1/3-(-3/5)=
reduce to the simplest form.
The simplest form after solving the given expression, -1/3-(-3/5), is
According to the question,
We have the following expression:
-1/3 -(-3/5)
We know that when a number or a sign is in bracket then it means that it should be multiplied with the numbers or sign outside of the bracket.
We also know that multiplication of two negative numbers gives us the positive result.
-1/3 + 3/5
Now, we change the order of fractions without changing their signs.
3/5 - 1/3
Now, we will make the denominator same by taking least common factor of 5 and 3 (which is 15) and we will subtract the fraction:
(3*3 - 1*5)/15
(9-5)/15
4/15
Now, this fraction can not be divided by the same number in numerator and denominator. So, this is the simplest form.
Hence, the simplest form after solving the expression is 4/15.

Rosa Went to have a manicure that cost $25 she wanted to tip the technician and 15% and tax is 7% how much did she spend total for the manicure
The correct answer is $30.5 or $31 if rounded
Explanation:
To find the total Rosa spent on the manicure, it is necessary to calculate the money spent on taxes and the money she tipped to the technician. The process is shown below:
Taxes:
$25 represents 100% of the cost and 7% percent represents the total taxes.
1. Write the values using x as the value you want to know
25 = 100
x = 7
2. Use cross multiplication
x 100 = 175
3. Solve this equation
x = 175 / 100
x = 1.75 (Total price for taxes)
Tip:
Repeat the process but in this case calculate the 15% of $25
25 = 100
x = 15
x 100 = 375
x = 375 / 100
x = 3.75
Total: Finally, add the three values
$25 (cost of the manicure) + $ 1.75 (taxes) + $3.75 (tip) = $30.5 or $31 if rounded

Which of the following lines is parallel to the line y = −

x + 1 and contains the point (4,-2)?
Answer:
y=-32+126
Step-by-step explanation:
So the equation you've given me is: y=-32x+1 which is already in slope intercept form.
The slope remains the same so let's look at the y-intercept (b) which is not going to come into solving it.
Plug in the points into the equation to become: -2=-32(4)+b
Solve the equation to get 126=b
Plug it into your new equation: y=-32x+126
The graph of a polynomial function f is shown
a. Is the degree of the polynomial odd or even? Explain how you know.
b. That is the constant term of the polynomial
Answer:
The degree of the polynomial is even because it is a 4th degree polynomial. 4 is even, so the graph will behave roughly like a quadratic; namely, its graph will either be up on both ends or else be down on both ends.
The y-intercept is the constant term. The constant term is -4 because it is the only number on the y-axis.

1. Parallelogram WXYZ is shown on the coordinate plane ect...
Added photo plz help!!
Answer:
Step-by-step explanation:
12.718 units
Step-by-step explanation:
The coordinates of the vertices of parallelogram WXYZ are given to be W(0,-1), X(4,0), Y(3,-2) and Z(-1,-3).
So, the perimeter of the parallelogram will be 2(WX + XY) {Since opposite sides of parallelogram are same in length}
Now, length of WX = units, To find the units click this link :
https://tex.z-dn.net/?f=%5Csqrt%7B(-1)%5E%7B2%7D%20%2B%204%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B17%7D%20%3D%204.123
And, length of XY = units, To find the units click this link :
https://tex.z-dn.net/?f=%5Csqrt%7B(4-3)%5E%7B2%7D%20%2B%20(0-(-2))%5E%7B2%7D%7D%20%3D%20%5Csqrt%7B5%7D%20%3D%202.236
Therefore, the perimeter of the parallelogram WXYZ = 2(4.123 + 2.236) = 12.718 units. (Answer)
