Answer:
yes
number of tiles needed = (200 x 200) / (30 x 30) = 44.4
Step-by-step explanation:
number of tiles needed = Area of comfort room / area of tiles
Area of a square = length²
convert area of comfort room to cm
100 cm = 1 meter
2 x 100 = 200
number of tiles needed = (200 x 200) / (30 x 30) = 44.4
50 tiles are more than enough to tile the room
We need to convert this equation to slope-intercept form first.
We can do that by solving for y.
x - 5y = 15
<em><u>Add 5y to both sides.</u></em>
x = 5y + 15
<em><u>Subtract 15 from both sides.</u></em>
x - 15 = 5y
<em><u>Divide both sides by 5.</u></em>
y = 1/5x - 3
We now know the slope is 1/5.
The slope of the line perpendicular to the line with a slope of 1/5 is -5.
The slope of a perpendicular line is the negative reciprocal of the original slope.
Using a graphing calculator, we know the y-intercept of the line that is perpendicular to the original line must have a y-intercept of -6 to run through the points (-2, 5).
The equation of the new line is y = -5x - 6.
First a reciprocal is a fraction but flipped over. So so if we have x/y, it's recipricam is y/x.
this helps to know when you understand that dividing by a fraction is the same thing as multiplying by that fractions reciprocal.
So ifnwenhave b/c and divide it by x/y we can also say b/c multiplied by y/x. it isnthensame thing.
now to use this for your problem.
5/31 divided by 15/23
or
5/31 times 23/15
all we have to do is multiple the 2 numerator and denominator and get:
115/465
now to reduce. divide both by 5 first
23/91
both numbers are prime so that would be answer
