Answer:
I think one tailed correct me if im wrong
He would need exactly 20 more dimes.
42 x 18 = 756
776 divided by 756 = 20
Answer: 84 ft^2
Step-by-step explanation:
The whole prism can be divided into 5 surfaces.
Two triangles and 3 rectangles.
Find the area of each of the 5 shapes and add them together.
The triangle has a base of 4 and a height of 3.
Area of triangle 1: A= 4*3 * 1/2
A = 6
Area of triangle 2: A = 4*3 * 1/2
A = 6
Area of rectangle 1 : A= 4*6
A = 24
Area of rectangle 2; A = 3*6
A = 18
Area of rectangle 3: A= 5 *6
A = 30
Now add the areas together
6 + 6 + 24 + 18 + 30 + = 84 ft^2
Answer:
c) (7, 9)
Step-by-step explanation:
Simply add the corresponding coordinates.
Answer:
30 square feet
Step-by-step explanation:
Number of tiles used for covering the kitchen floor = 10
Area covered by the floor = 6 * 5 feet^2
= 30 square feet
Length of each tiles = 3 feet
Width of each tiles = w feet
Area covered by each tiles = 3w square feet
Then the equation can be written as
3w * 10 = 30
30w = 30
w= 30/30
= 1 feet
10 *3w = 30
