First convert feet to inches:
18 ft × (12in/1ft)= 216 in
15 ft × (12 in/1ft)= 180 in
divide each side of the room by 9 inches to get number of white tiles per a wall
wall 1(18ft): 216in/9in= 24 white tiles
wall 2(15ft): 180in/9in= 20 white tiles
wall 3(18ft): 216in/9in= 24 white tiles
wall 4(15ft): 180in/9in= 20 white tiles
Lastly, add up all the white tiles and subtract 4 (the tiles that we counted twice because they were the corner tiles and touched both walls)
24+20+24+20-4= 84 white tiles total
Answer:
(x - 5)(x - 5)
Step-by-step explanation:
Given the expression
x^2 - 10x + 25
Look for the factors of x^2 and 25.
The factors are x and 5.
Therefore,
(x -5) (x-5)
When you distribute , you have
X x X - X x 5 - 5 x X - 5 x -5
x^2 -5x - 5x +25
x^2 - 10x + 25
Answer:
The answer is A for this
Since A is the only graph showing correct location of the coordinates of F and G while the others showing different coordinates of these 2 points.
The probability for A is 0.0952380952 and the probability for B is 0.272727273
The measure of m<CBD is 63 degrees
<h3>Circle Geometry</h3>
According to line geometry, the sum of angles on a straight line is expressed as:
arcCD + m<CBF = 180
Given that
arcCD= 5x + 3 and;
m<CBF = 11x - 15
Substitute
5x + 3 + 11x - 15 = 180
16x - 12 = 180
16x = 192
x = 12
Determine the measure of m<CBD
m<CBD = arc CD = 5x + 3
m<CBD = 5(12) + 3
m<CBD = 63 degrees
Hence the measure of m<CBD is 63 degrees
