Answer:
Step-by-step explanation:
The measure of the floor of the rectangular room that is 12 feet by 15 feet. The formula for determining the area of a rectangle is expressed as
Area = length × width
Area of the rectangular room would be
12 × 15 = 180 feet²
The tiles are square with side lengths 1 1/3 feet. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet
Area if each tile is
4/3 × 4/3 = 16/9 ft²
The number of tiles needed to cover the entire floor is
180/(16/9) = 180 × 9/16
= 101.25
102 tiles would be needed because the tiles must be whole numbers.
Answer:
6.45 feet
Step-by-step explanation:
He starts 17 and 1/2 feet off the ground
Elevation relative to ground: 17 1/2
Then he increases the height by 4 and 3/4
Expression: 17 1/2 +4 3/4
Elevation relative to ground: 22 1/4
Next he decreases the elevation by 15.8 feet
Expression: 22.25-15.8
Elevation relative to ground: 6.45
The answer 6.45 feet from the ground
For perimeter you can find it 2 ways:
l=length, w=width
(2)l+(2)w=perimeter
or just:
l+l+w+w= perimeter
Hope this helps!!!
Answer:
Mean: 49
Step-by-step explanation:
The mean is the sum of all of the numbers divided by the total number of numbers. So, there are 7 numbers you gave.
The sum of 45+50+47+52+53+45+51 = 343.
Divide 343 by 7 and you get 49.
Answer:
Median: 50
Step-by-step explanation:
The median is the middle number when you sort out the entire list. First, you have to sort out the entire list:
45, 45, 47, 50, 51, 52, 53
Then, pick out the middle number. The middle number will always have the same number of numbers on either side. 50 is in the middle, and there are three numbers on either side of the 50.
