Step-by-step explanation:
Vanessa works 32 hours per week at her job. Her boss offers her a full time job (40 Hours per week) and a 2 dollar per hour raise. She says "this is great now I'll make 200 more per week". What is Vanessa's hourly wage before the raise?
Answer:
$35.75 per hour
Step-by-step explanation:
In order to calculate this, we first need to calculate how much she made with her current hourly wage. We do this by multiplying the hours she worked by her current hourly wage plus her raise.
32 hours * (40+2) = $1,344
Now we subtract $200, since this is how much more she is making with her raise, and then we divide that amount by the 32 hours she is working per week.
(1,344 - 200) / 32 = $35.75 per hour
Finally, we can see that Vanessa's hourly wage before the raise was $35.75 per hour

On Monday. I bought 3 shirts and 7 pairs of pants for a total cost of $17.25. On
Tuesday, I bought 3 shirts and 9 pairs of pants for a total cost of $20.25. Can you
find the price of each item?
Answer:
Shirt: $2.25. and Pants: $1.50
Step-by-step explanation:
Set up equations with shirts as s and pants as p.
3s+7p=17.253s+9p=20.25Subtract them as there are two variables and two equations:
-2p=-3Make positive, 2p=3Divide, p=1.5To find s:
3s+7(1.5)=3s+10.5=17.25, so 3s=6.75 and s=2.253s+9(1.5)=3s+13.5=20.25, so 3s=6.75 and s=2.25here is a better picture

Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.
Complete question :
On average, light emitted from the Sun takes 8 minutes 19 seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.
Answer:
1.497 * 10^8km
149700000 km
Step-by-step explanation:
Given that:
Time taken = 8 minutes 19 seconds
Speed of light = 3 * 10^8 m/s
Distance from earth to sun :
Speed * time
(3 * 10^8) * ((8 * 60) + 19)
(3 * 10^8) * 499
= 1497 * 10^8 m or 1497 * 10^5 km = 1.497 * 10^8km
= 149700000000 m
= 149700000 km
= 1497

Jenna has one more logic puzzle to solve!
Write a system of equations to represent this puzzle, using b to represent the value of each book and m to represent the value of each music note. Then solve the system for b and m.
Type the correct answer in each box. Use numerals instead of words.
The value of each book is
.
The value of each music note is
.
Answer:
The value of each book is 7
The value of each music note is 6
Step-by-step explanation:
The first equation includes the sum of 3 books and 2 music notes, so 3b + 2m = 33.
The second equation includes the sum of 1 book and 3 music notes, so b + 3m = 25.
This is the system that represents the puzzle:
3b + 2m = 33
b + 3m = 25
Solve the second equation for b, and then substitute the equivalent expression for b in the first equation. The value of each music note is 6.
Then, Substitute the value of m into one of the original equations to find the value of b . The value of each book is 7.

Answer: 3mn^2.
Step-by-step explanation: GCF stands for Greatest Common Factor, as you know. The greatest common factor of 75 and 27 is 3. For the rest, we just use the smallest values. Thus, the answer is 3mn^2.
The sum of a whole number and twice the square of the number is 10. Find the number
Answer:
Hey there !
Solution:
Let the number be x
=> x + 2x² = 10
=> 2x² + x - 10 = 0
Factorising the quadratic equation we get,
=> 2x² + 5x - 4x - 10 = 0
=> x ( 2x + 5 ) -2 ( 2x + 5 ) = 0
=> ( x - 2 ) ( 2x + 5 ) = 0
=> x = 2, -5/2
Since x is a whole number, -5 / 2 wont be applicable.
Hence x = 2.
Hence the number is 2.

What is the midpoint of the line segment with endpoints (-2,-4) and (4,6)?
A. (-6,10)
B. (-3,5)
C. (1,1)
D. (2.2)
E. (3,5)
Answer:
Answer: C. (1,1)
Step-by-step explanation:
Midpoint
Given a segment defined by points (x1,y1) and (x2,y2), the midpoint (xm,ym) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
The endpoints are (-2,-4) and (4,6).
Calculating the midpoint:
[tex]\displaystyle x_m=\frac{-2+4}{2}=\frac{2}{2}=1[/tex]
[tex]\displaystyle y_m=\frac{-4+6}{2}=\frac{2}{2}=1[/tex]
The midpoint is (1,1).
Answer: C. (1,1)
A candle has been burning for 20 min and is now 25 cm tall. In an hour it will be 10 cm tall. Which equation models the height y of the candle in centimeters, x minutes after it was lit?
Answer:
(y - 25) = - 0.25(x - 20)
Step-by-step explanation:
Given that :
Height of candle after burning for 20 minutes = 25 cm
Height after burning for 1 hr (60 minutes) = 10 cm
Height (y) in cm of candle x minutes after being lit:
Using the equation :
(y - y1) = m(x - x1)
m = (change in y / change in x)
Change in height within 60 minutes :
Height at 20 minutes = 25cm
Height after an hour = 10
Change in height per hour = (25 - 10) = 15cm
Hence, m = change in height per minute
15cm / 60 = 0.25cm ( - 0.25) (decrease in height)
y1 = 25 ; x1 = 20
(y - y1) = m(x - x1)
(y - 25) = - 0.25(x - 20)

Step-by-step explanation:
y=3/4x-2
Answer:
y=3/4x-2
Step-by-step explanation:
slope-intercept formual: y = mx + b
m (the slope) = (y2-y1) / (x2-x1) so right here we insert (4-1) / (8-4) = 3/4
b =w here the line touches the y-asix = -2
now insert those numbers in the formual: y = (3/4)x + (-2)
final answer: y=3/4x-2

Factorise 4(x+y)(3a-b)+6(x+y)(2b-3a)
Please solve this fast.
Show your calculation.
Answer:
(-3a+4b) (2x+2y)
Step-by-step explanation:
Expand.
4(x+y)(3a-b)+6(x+y)(2b-3a) = 4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)
4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay) = 12ax+12ay-4bx-4by+12bx+12by-18ax-18ay
Calculate like terms.
12ax+12ay-4bx-4by+12bx+12by-18ax-18ay = -6ax-6ay+8bx+8by
Factorise.
-6ax-6ay+8bx+8by = -3a(2x+2y) + 4b(2x+2y)
Factorise further.
-3a(2x+2y)+4b(2x+2y) = (-3a+4b) (2x+2y)

Answer:
x = 17
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
6x - 15 + 4x - 7 + 2x - 2 = 180, that is
12x - 24 = 180 ( add 24 to both sides )
12x = 204 ( divide both sides by 12 )
x = 17
5n + 20 -10 + 15n=50
Solve for the variable
Step-by-step explanation:
2n is the answer because you combined the two variables then you do 20n plus 20n minus. 10 equals 50 then subtract 10 from 50 and get forty the divide that by 20 which equals 2
