Step-by-step explanation:
Find the cross-sectional area first of the trapezium
[tex]\frac{1}{2} (a+b)h[/tex]
So, [tex]\frac{1}{2}(6+34)15[/tex]
which is 40 / 2 x 15 = 20 x 15 = 300 [tex]cm^{2}[/tex]
Since there are 2 trapeziums (on the front and back): 300 x 2 = 600[tex]cm^{2}[/tex]
Find the Area of the Rectangles
The first rectangle on the top would be: 6x30 = 180 [tex]cm^{2}[/tex]
The slanted rectangle on the right would be: 25x30 = 750 [tex]cm^{2}[/tex]
The rectangle on the bottom would be: 30x34 = 1020 [tex]cm^{2}[/tex]
The hidden rectangle on the left would be: 17 x 30 = 510 [tex]cm^{2}[/tex]
So by combining all these calculations, you will get the total surface area which is:
600 + 180 + 750 + 1020 + 510 = 780 + 1770 + 510 = 2550 + 510 = 3060 [tex]cm^{2}[/tex]

Answers
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

Step-by-step explanation:
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?
Answers
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.

A shape is rotated counterclockwise 110 degrees about the origin. What is another way to describe the rotation?
Answers
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.

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.
Answers
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

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!
Answers
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.
