Angelo makes x dollars for y hours of work. Sarah makes the same amount of money working 1 hour less. Which of the following expressions represents the positive difference between the two people's hourly wage? Enter a, b, c, d, or e. a. -1 - b. - y-1 c. y 1 + d. Y- 1 y-1 w х у e. y х Enter
Answer:
A
Step-by-step explanation:
x/y - x/y-1
But remember the fraction with the bigger denometer is the smaller number
x/y is the smaller number
therefore the answer is:
x/y-1 - x/y or A
The expression represents the positive difference between the two people's hourly wage is x.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Given that, Angelo makes x dollars for y hours of work.
Money made by Angelo =x×y
= xy
Sarah makes the same amount of money working 1 hour less.
Number of hours Sarah worked is y-1
Money made by Sarah =x×(y-1)
= xy-x
So, difference in their money
xy-(xy-x)
= xy-xy+x
= x
Therefore, the expression represents the positive difference between the two people's hourly wage is x.

I need this fast!
Answer: 8 1/20 or 8.05.
Step-by-step explanation: First you would want to make 9 3/4 - 2 1/5 to 39/4 - 11/5. We need to get the LCD or Least Common denominator of 4 and 5, which is 20. The rule is what you multiplied the denominator by you must multiply the numerator by, so our new equation is 195/20 - 44/20, which is 151/20. Now, we have to find the LCD of 2 and 20, which is 10. So 151/20 + 10/20 is 161/20 or 8 1/20.

i have a question for u
using the elimination method, what is x and y ( please explain, I am still slightly confused)
x + 3y= -1
-2x - 3y=5
Answer:
(- 4, 1 )
Step-by-step explanation:
Given the 2 equations
x + 3y = - 1 → (1)
- 2x - 3y = 5 → (2)
Adding the 2 equations term by term will eliminate the y- term
- x + 0 = 4
- x = 4 ( multiply both sides by - 1 )
x = - 4
Substitute x = - 4 into either of the 2 equations and solve for y
Substituting into (1)
- 4 + 3y = - 1 ( add 4 to both sides )
3y = 3 ( divide both sides by 3 )
y = 1
solution is (- 4, 1 )

Brady needs to cut a piece of scrapbook paper
12 centimeters long. He cuts pieces of the following
lengths. Which cut results in a percent error of 15%?
Select all that apply.
Answer:
Option A and Option C
Step-by-step explanation:
If we know that we have to cut a peice of paper 12 centemiters long, that means a 15% error would be cutting out one of the following lengths....
12 - 12(0.15) = 10.2 cm
or
12 + 12(0.15) = 13.8cm
So from this, we see that the answers are Option A and Option C

Answer:
The distance is 29.3 feet
Step-by-step explanation:
Here, we want to find the distance from the diving board to the bottom of the pool
To get this, we will need to add the height of the diving board above the ground plus the distance of the bottom of the pool below the ground
Mathematically, we can have this as:
12.4 + 16.9
= 29.3 feet

Sqaure root of 3 divided by 2
Step-by-step explanation:
The value of function sin 60° is √3/2.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
We need to find the value of sin 60°
Sin 60 degrees is nothing but sin π/3
The sine function we obtain by dividing the opposite side by hypotenuse.
sin theta = Opposite side/ hypotenuse
sin 60=√3/2
The value of sin 60 degrees is square root of three by two.
Hence, the value of function sin 60° is √3/2.
