Answer:
the room will be 80 inches by 100 inches
( 1 inch ----> 20 inches
so 4 inches ----> 80 inches )
or
6 2/3 ft by 8 1/3 ft
The area of the given room is 166 2/3 ft².
What is a scale drawing?A scale drawing is a reduced form in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension.
The area of the room can be calculated as;
The length of the room = 20 x 4 = 80 inches
The width of the room = 20 x 5 = 100 inches.
Now, 1 inch = 1/12 foot
80 inches / 12 = 6 2/3 ft
100 / 12 = 8 1/3 ft
The Area = 6 2/3 x 8 1/3
The Area = 25/3 x 20/3
The Area = 500 / 3
The Area = 166 2/3 ft²
Therefore, The area of the given room is 166 2/3 ft².

okay yes i need a lot of help okay
Answer:
either 78.4cm or 288.4cm
Step-by-step explanation:
rectangle area
A = 15x4
A = 60
Area of 2 triangles
A = 4.6x4/2
A = 9.2x2
A = 18.4
18.4 + 60 = 78.4cm
Maybe the answer
Area of 2 rectangles
A = 15x4
A = 60
A = 15x14
A = 210
Area of 2 triangles
A = 4.6x4/2
A = 9.2x2
A = 18.4
60 + 210 + 18.4 = 288.4cm
either answer hope one is right
Answer:
228.4
Step-by-step explanation:
Both triangle surface:
4x4.6 and then divide by 2 = 9.2
That will be the surface for one triangle
But there are two triangles so we times that by 2
That will be 18.4
Both big rectangle surface: (the top and bottom ones)
15x5=75
But we have two rectangles
So we times that by two and the answer will be =150
Smaller rectangle: (the one between two triangles)
4x15=60
Okay, now we add them all up, the triangles and rectangles
60+150+18.4=228.4

You need to add the bottom and the top of the trapezoid, times the height, and divided them by two.
Answer:
60 m^2
Step-by-step explanation:
The area of a trapezoid of lengths a and b is equal to the average length times the width. Here the average length is 30/2 m, or 15 m, and the width is 4 m. Thus the area is (15 m)(4 m) = 60 m^2 (Answer B)

Coach Cliffman made a deposit of $1,800 into an account that earns 2% annual compound interest. Find the amount of interest that Coach Cliffman earned after 3years.
Answer: 5508$
Step-by-step explanation:
So to find interest your formula is this:
Int=interest rate (percent)*principal
So your problem would be: int=.02*1800
This equals 36. Since its interest, you add your interest (36) and your principal (1800) and get 1836. Now, since you need to find the interest for 3 years, you multiply 1836 by 3.

Answer:
d. 128 cm^3
Step-by-step explanation:
to find the volume its length time width times heights; so 4 cm times 4 cm time 4 cm which is 64. Since the dice are the same size you add 64 cm^3 to 64 cm^3 to get 128 cm^3

Amanda has 227 worth of bills in her purse. she has 6 more $5 dollar bills than $10 bills. The number of $1 bills is three fewer than 25 times the number of $10 dollar bills. How many of each does amanda have?
Answer:
Step-by-step explanation:
x = $5 dollar bills
y = $10 dollar bills
x + y = 15
5x + 10y = 120
5x + 10(15-x) = 120
5x + 150 - 10x = 120
-5x = -30
x = 6, so y = 9
There are six $5 bills and nine $10 bills.
