John works 20 hours per week at a part-time job. His original pay rate was $10.50
per hour, but he recently received a pay cut of x dollars per hour for being late to
work too many times. His total weekly pay, y, is represented by the equation
y=20(10.50-x).
If John's earned $160 for the week, what was the amount of his pay cut?
$1.50
$2.50
$2.00
$1.00
Answers
Answer:
2.50$
Step-by-step explanation:
y=20(10.50-x).
160 = 20 (10.50-x)
160 = 210 - x
160 - 210 = -x
-50 = -x
50 = x
50$ Is the total per week, divided by the number of hours 20. You’ll have the cut per hour.
50/20 = 2.50
Answer:
x = $2.50
Step-by-step explanation:
y = 20(10.5 - x)
$160 = 20(10.5 - x ) {use distributive property}
160 = (20*10.5) - (20*x)
160 = 210 - 20x {Add 20x to both sides}
160 +20x = 210 {Subtract 160 from both sides}
20x = 210 - 160
20x = 50
x = 50/20
x = $2.50

Step-by-step explanation:
THATS IT I THINK sorry caps
Answer:
0 and - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(a)
y = 3x or y = 3x + 0 has c = 0 ← y- intercept
Thus line passes through the origin
(b)
y = - x - 2 has m = - 1 ← slope
A landscaping business bought 8 rose bushes and 15 daylilies for $193. They went back later and bought 3 more rose bushes and 12 daylilies for $117. How much does each daylily cost?
Answers
Answer:
Each daylilies cost $7
Step-by-step explanation:
Step one:
let roses be x
and daylilies be y
so
8x+15y=193--------------1
also
3x+12y=117--------------2
we can solve equations 1 and 2 by substitution
8x=193-15y
x=(193-15y)/8
put x= (193-15y)/8 in 3x+12y=117
3((193-15y)/8)+12y=117
(579-45y)/8+12y=117
579-45y=8(117-12y)
579-45y=936-96y
collect like terms
579-936=-96y+45y
-357=-51y
divide both sides by -51
y=-357/-51
y=7
Hence each daylilies cost $7
put y=7 in eqn 1
8x+15(7)=193
8x+105=193
8x=193-105
8x=88
x=88/8
x=11
rose cost $8

The length of the garden is 10 feet more than twice its width. The perimeter of the garden is 170 feet.
What are the length and width of the garden?
Answers
Answer:
Width is 25 ft
length is 60 ft
Step-by-step explanation:
Here, we want to calculate the length and width of the garden
From the question, we are told that the length is 10 ft more than twice its width
So if the width is x ft
Length = 2x + 10
Mathematically, the perimeter of a rectangle i s 2(l + b)
So;
2(x + 2x + 10) = 170
2(3x + 10) = 170
3x + 10 = 85
3x = 85-10
3x = 75
x = 75/3
x = 25 ft
length is;
2(25) + 10 = 50 + 10 = 60 ft

If the red square has an area of 200 square centimeters and the green square has an area of 60 square centimeters, then was is the area of the yellow square?
Answers
Answer:
140
Step-by-step explanation:
You want the area. You do not have to take the square root. First of all you have to assume this is a right angle triangle.
c^2 = b^2 + a^2
c^2 = 200
b^2 = 60
a^2 = ?
200 = 60 + a^2
200 - 60 = a^2
a^2 = 140
Brad buys two packages of mushrooms. He paid $11.25 for 2/3 lb of Cremini mushrooms and $7.99 for 1/2 lb of Chanterelle mushrooms. Which mushroom cost less per pound?
A. Cremini mushrooms cost less by $0.10
B. Chanterelle mushrooms cost less by $0.10
C. Chanterelle mushrooms cost less by $0.90
D. Cremini mushrooms cost less by $0.90
Answers
I think the answer is B if you ask me
Answer:
C. Chanterelle mushrooms cost less by $0.90 is correct.
Step-by-step explanation:
1. For the Cremini mushrooms, we know it costs $11.25 for 2/3 lb. So, let's divide this amount by 2 to get the amount of money per 1/3 lb of Cremini mushrooms.
11.25 ÷ 2 = 5.63 when rounded to the nearest cent.
Now, let's multiply this by 3 to get the price of 1 lb of Cremini mushrooms.
5.63 x 3 = 16.89
Therefore, 1 pound of Cremini mushroom is $16.89.
2. For the Chanterelle mushrooms, we know that it cost $7.99 for 1/2 lb. So, let's multiply this amount by 2 to get the price per pound.
7.99 x 2 = $15.98
Therefore, 1 pound of Chanterelle mushroom is $15.98.
3. To find the difference between two prices, subtract the price of the smaller quantity (Chanterelle mushroom) from the larger quantity (Cremini mushroom.)
16.89 - 15.98 = $0.91
Even though this answer doesn't match with the exact answer, because we rounded to the nearest cent, we can agree that C. is correct.

Answer:
12 yards per second = 36 feet per second
Formula: multiply the value in yards per second by the conversion factor '3'.
So, 12 yards per second = 12 × 3 = 36 feet per second.
Step-by-step explanation:
To calculate a yard per second value to the corresponding value in ft/s, just multiply the quantity in yd/s by 3 (the conversion factor).
Here is the formula:
Value in ft/s = value in yd/s × 3
Suppose you want to convert 12 yd/s into ft/s. Using the conversion formula above, you will get:
Value in ft/s = 12 × 3 = 36 ft/s

A roller coaster climbs to a height of 248m before it goes into an underground tunnel that is 16m below ground. What is the height difference between the highest point and the lowest?
A) -232
B) -264
C) 264
D) 232
Answers
===========================================================
Explanation:
Draw a vertical number line. Mark the values 248, 0, and -16 on the number line. The negative value is to indicate it is below 0, while the positive number is above 0.
The distance from 248 to 0 is 248 units. Let A = 248.
The distance from 0 to -16 is 16 units. Let B = 16
The total distance mentioned so far is A+B = 248+16 = 264
So basically if we start at the highest point (248) and go to the ground level, we traveled 248 meters. Then we travel another 16 meters to go from ground level to the lowest point (-16) leading to a total of 248+16=264 meters in total distance from highest to lowest point.
