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

Answer:
Step 1: Draw the points TUVW using the given coordinates (you already did T).
Step 2: For the reflection, in each coordinate replace the x coordinate with -x. E.g., T becomes T' (6,1). Reflection in y axis means the x coordinates swap their sign.
Step 3: Draw the reflected rectangle T'U'V'W'.
Step 4: Replace each coordinate of step 3 with x-5 and y+7, e.g., T' becomes T'' (1, 8)
Step 5: Draw T''U''V''W''
Answer:
see explanation
Step-by-step explanation:
(a)
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , thus
T(- 6, 1 ) → T'(6, 1 )
U(- 1, 0 ) → (1, 0 )
V(- 2, - 5 ) → V'(2, - 5 )
W(- 7, - 4 ) → W'(7, - 4 )
(b)
The translation rule (x, y ) → (x - 5, y + 7 ) means
Subtract 5 from the original x- coordinate and add 7 to the original y- coordinate, that is
T(- 6, 1 ) → T'(- 6 - 5, 1 + 7 ) → T'(- 11, 8 )
U(- 1, 0 ) → U'(- 1 - 5, 0 + 7 ) → U'(- 6, 7 )
V(- 2, - 5 ) → V'(- 2 - 5, - 5 + 7 ) → V'(- 7, 2 )
W(- 7, - 4 ) → W'(- 7 - 5, - 4 + 7 ) → W'(- 12, 3 )
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.

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

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

En un colegio hay 315 alumnos de los cuales 1/3 son mujeres y el resto hombres. 2/7 de los hombres juegan al fútbol y el resto al baloncesto. ¿Cuántos hombres juegan al baloncesto?
Answers
Answer:
150 hombres juegan baloncesto.
Step-by-step explanation:
En una escuela hay 315 alumnos de los cuales 1/3 son mujeres y el resto son hombres.
Paso 1
Encontramos el número de estudiantes que son mujeres
= 1/3 × 315
= 105 mujeres.
Se nos dice que el resto son hombres. Por lo tanto, el número de hombres que son estudiantes se da como:
= 315 - 105 mujeres
= 210 hombres
Paso 2
2/7 de los hombres juegan fútbol y el resto baloncesto.
Esto significa que 2/7 de 210 hombres juegan al fútbol
= 2/7 × 210 hombres
= 60 hombres
Por tanto, 60 hombres juegan al fútbol.
Paso 3
También se nos dice que el resto juega al baloncesto.
El número de hombres que juegan baloncesto se calcula como:
210 - 60
= 150 hombres.
Por tanto, 150 hombres juegan baloncesto.

The day you were born your parents invested $5,000 in CD account (Certificate of Deposit).
The account pays 0.88% annual interest rate. How much money will be in your account by
your high school graduation (18 years)?
Plz help. I need an answer and explanation step by step plz
Answers
Answer:
You will have $5,792 in your account by your high school graduation
Step-by-step explanation:
Simple Interest
Interest calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
The parents invested P = $5,000 in CD account that pays r=0.88% annual interest rate. The rate must be converted to decimal, thus r=0.88/100 =0.0088.
We are required to calculate the total money in the account after t=18 years.
First, we calculate the interest:
I = $5,000 * 0.0088 * 18
I = $792
Adding interest to the principal, we have the future balance in the account:
A = $5,000 + $792 = $5,792
You will have $5,792 in your account by your high school graduation
