28/11.2 = 2.5
since they are similar and openly stated as parrallelograms, you know that they have a scale of the longest edge of EFGH to the longest edge of JKLM
4.) The lateral area of a figure is the area of the figure with the exception of the bases.
Given a prism with right triangle bases, the lateral area of the prism is the sum of the areas of the rectangles making up the prism.
This is given by
Lateral area = (8.94)(41) + (4)(41) + (8)(41) = 366.54 + 164 + 328 = 858.54 ≈ 859 m^2
The surface area is the sum of the bases plus the lateral area. The area of a rectangle is given by half base times height.
Surface area = 1/2 x 8 x 4 + 1/2 x 8 x 4 + 859 = 16 + 16 + 859 = 891 m^2
5.) The surface area of a cylinder is given by pi r^2h where r is the radius = 12 inches and h is the height = 17 inches.
Surface area = π x (12)^2 x 17 = 2,448π = 7,690.62 in^2 ≈ 7,691 in^2
Answer:
The Tip amount is $ 9
Step-by-step explanation:
Given as :
The total dinner bill = $ 61.31
Rounding the bill to nearest ten dollars
The value of bill after rounding it to ten dollars = $ 60
Now The percentage of tips = 15% of dinner bill
So, The amount given as tip = 15% × $ 60
Or, The amount given as tip = $ 9
Hence The Tip amount is $ 9 Answer
Answer:
D
Step-by-step explanation:
1 1/4 + 1 1/2
First change the mixed fractions into improper fractions.
Do this by multiplying the denominator by the whole number, then adding that to the numerator, leaving the denominator the same.
5/4 + 3/2
Now change the fractions so that they have a common denominator.
Here, you can use 4 as the CD, so leave the first fraction alone and just change 3/2.
3/2 = 6/4
5/4 + 6/4 = 11/4
11/4 can be changed into 2 3/4.
So the answer is 2 3/4 or 2.75.
