Denise is going to shop with the $250.00 that she earned from doing chores. She wants to save 20% of her money to put into a savings account. She buys a pair of jeans for $75.00 and a new leather coat for $110.00, with 5% sales tax on both items. Does Denise still have the amount of money she planned to put into her savings account?
Answer:
Yes
Step-by-step explanation:
Money to put into Savings Account
20% of $250.00 = 0.2 × $250.00
= $50.00
Cost of Jeans with sales tax
$75.00 + 5% = 105% of $75.00
= 1.05 × $75.00
= $78.75
Cost of Coat with sale tax
$110.00 + 5% = 105% of $110.00
= 1.05 × $110.00
= $115.50
Total money spent
= $78.75 + $115.50
= $194.25
Money left
= $250.00 - $194.25
= $55.75
$55.75 > $50.00
As the money left is more than 20% of $250.00 she does still have the money she planned to put into her savings account.
Tim uses a food delivery service to order dinner for himself and a friend. He paid $37.05 for dinner, which included the cost of the food and a delivery fee of 14% of the cost of the food. What was the cost of their dinner before the delivery fee?
Please explain!
Answer:
$31.86
Step-by-step explanation:
You can use a proportion here.
37.05 = 100%
x = 86% (100%-14% which is a delivery fee)
x = (37.05*86)/100
x = 3186.3/100
x = 31.86
The cost of their dinner before the delivery fee was $31.86.

For a 5.0 µC point charge moved within an electric field, the electric potential difference is mathematically given as
du=2*10^6
What is the electric potential difference before and after the charge was moved?Generally, the equation for the change in potential energy is mathematically given as
dV=qdu
Therefore

The surface area of a rectangular prism is 1220 cm^2.
What is a rectangular prism?A rectangular prism is a 3-d solid shape that has 6 rectangular faces in which all the pairs of opposite faces are congruent. It has 8 vertices, 6 faces, and 12 edges.
For the given situation,
A rectangular prism has dimensions,
Length = 17 cm
Breadth = 14 cm
Height = 12 cm
The formula to find the surface area is A= ( lb + bh +lh)
⇒ [tex]A=2[(17)( 14) + (14)( 12) + (17)( 12)][/tex]
⇒ [tex]A=2(238+168+204)[/tex]

Answer: -35.375 or -283/8
Step-by-step explanation:
Begin with the parenthese: (-1.5+9.5)=8 and (7+11)
Then you have 5/8+0.4(18)/-0.2.
Multiply 0.4 times that 18 and you get 7.2.
Then you have 5/8+7.2/-0.2
Simplify 7.2/-0.2 which equals -36
Then you have 5/8+-36
5/8+-36=-35.375 or in fraction form -283/8

A shape is rotated counterclockwise 110 degrees about the origin. What is another way to describe the rotation?
At max a rotation can be equal to π or 180°
So if it's rotated 110° counterclockwise then it's equal to rotation of supplementary angle clockwise
Supplementary angle=180-110=70°
70° rotation clockwise
When a shape is rotated counterclockwise 110 degrees about the origin, the rotation is described as 70 degrees clockwise.
What are supplementary angles?The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.
A shape is rotated counterclockwise 110 degrees about the origin which is given in the question
A rotation can have a maximum of 180 degrees.
So a rotation of 110 degrees counterclockwise equals a rotation of supplementary angle clockwise.
According to the property of supplementary angle,
⇒ 180° - 110°
⇒ 70°
Thus, when a shape is rotated counterclockwise 110 degrees about the origin, the rotation is described as 70 degrees clockwise.

The regression equation of sales of coffee is ŷ = -22.7x + 130.3, and the regression equation of sales of tea is ŷ = -22.7x + 119.0
How to determine the regression equations of the drinks?The dataset of coffee is given as:
Price: 1.50 2.20 2.70 2.50 2.90 2.00 1.60 2.10 3.00 1.80
Sales: 96 79 70 73 64 85 94 83 63 91
Using a graphing calculator, we have the following calculation summary:
Sum of X = 22.3Sum of Y = 798Mean X = 2.23Mean Y = 79.8Sum of squares (SSX) = 2.521Sum of products (SP) = -57.14b = SP/SSX = -57.14/2.52 = -22.7a = MY - bMX = 79.8 - (-22.67*2.23) = 130.3The regression equation is represented as:
ŷ = bx + a
So, we have:
ŷ = -22.7x + 130.3
The dataset of tea is given as:
Price: 2.40 1.50 1.10 1.60 2.50 1.30 1.00 1.70 2.20 2.00
Sales: 64 85 94 83 63 91 96 79 70 73
Using a graphing calculator, we have the following calculation summary:
Sum of X = 17.3Sum of Y = 798Mean X = 1.73Mean Y = 79.8Sum of squares (SSX) = 2.521Sum of products (SP) = -57.14b = SP/SSX = -57.14/2.52 = -22.7a = MY - bMX = 79.8 - (-22.67*1.73) = 119.0The regression equation is represented as:
ŷ = bx + a
So, we have:
ŷ = -22.7x + 119.0
Hence, the regression equation of sales of coffee is ŷ = -22.7x + 130.3, and the regression equation of sales of tea is ŷ = -22.7x + 119.0

URGETN DUE IN 20 MINUTES PLEASE HELP. Tammy went to Outback for dinner, and took Sue with her. The total bill cost $68.72. Service
was good so they left a 22% tip. If they split the bill, what did each of them pay for dinner.
Answer:
Step-by-step explanation:
find the tip
68.72 * 0.22 (22%) = 15.1184
I was hoping that 68.72 + 15.1184 would equal a nice round number, like if it had been 80 total, then they both could have dropped 40 dollars. which would make sense, and is probably what would really happen. But this is math, :D and it really doesn't have to make sense, it just has to be accurate.
so 68.72+15.12 = 83.84
83.84 / 2 =41.92 they each paid 41.92 or for crying out loud, would they really dig around for 92 cents? just give the waiter one whole dollar. So for accuracy they would each pay $41.92, but really they would each pay 42.00 dollars.. and to even be more real. they would each pay $40.00

The scale drawing is a parallelogram with a base of 8 inches, a height of 3 inches, and a side length of 4 inches.

The perimeter of the actual logo in inches whose base is 8 inches, height is 3 inches, and side length is 4 inches be,
Perimeter= 6 inches
What is scale factor?A scale factor is the ratio between corresponding measurements of an object and a representation of that object. If the scale factor is a whole number, the copy will be larger. If the scale factor is a fraction, the copy will be smaller.
The scale drawing of parallelogram having dimensions,
length= 8 inches,height= 3 inchesside length= 3 inchesPerimeter of scale drawing of parallelogram be,
= 2 ( length + side length)
= 2( 8 + 4 )
= 2 x 12

The drawing has a scale of 4: 1 (Here 4 represent for scale diagram and 1 represent for the actual diagram)
As scale factor,= [tex]\frac{Perimeter \;of\; Scale\; logo}{Perimeter \;of \;Actual\; logo}[/tex]
[tex]\frac{4}{1} = \frac{24}{Perimeter\; of \; Actual\; logo}[/tex]
Perimeter of Actual logo =[tex]\frac{24}{4}[/tex]
