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
Answer:
Step-by-step explanation:
Area of the field = pi * r^2
r = 230/2 = 115
Area of the field = 3.14 * 115^2 = 41526.5 square feet.
Number of bags = 41526.5/400 = 103.82 bags
Answer:
60 degrees
Step-by-step explanation:
I see 3 lines in the graphic.
1 horizontal line that gets crossed by 2 other lines - one at a 25 degree angle (and that line ends at the crossing point), and one at 60 degrees.
so, above and below the horizontal line, the line with 60 degrees and x degrees is the same line.
and therefore, as per the laws of crossing lines, the angles above and below the crossed line must be the same. they are just left-right mirrored.
therefore, x must be the same as the diametrically opposing angle above the horizontal line. and that is 60 degrees.
Answer:
D
Step-by-step explanation:
You need to sum up all and equal to 180
360 mm^3. There is 15 pennies also in the right side and you are already told the left side, which has 15 pennies is 360 mm^3.
