Answer:
24 Bricks.
Step-by-step explanation:
We know the radius is 6 feet and that the diameter is twice that.
We also know the radius is 12 'bricks' in length.
If we divide both numbers by 12, we get that 1 'brick' is half a foot.
Since that's the radius and we want the diameter, we multiply the radius by 2 to get the diameter.
This results in 12 feet, or 24 'bricks'.
Let x represent the length of the shorter leg.
Longer leg: 5x +19
Hypotenuse: 5x +20
Pythagorean theorem:
.. x^2 +(5x +19)^2 = (5x +20)^2
.. x^2 +25x^2 +190x +19^2 = 25x^2 +200x +20^2 . . . . . . eliminate parentheses
.. x^2 -10x -39 = 0
.. (x -13)(x +3) = 0
.. x = 13 . . . . . . . . . . leg lengths must be positive
The side length of the triangle are 13, 84, 85 feet.
Answer:
0.375
or
3/8
Step-by-step explanation:
used a calculator to do 3/4 and added it to -3 then divided that by -10
Number of kittens Ryan has = 8
Number of white kittens = 2
Number of not white kittens = 8 -2 = 6
Fraction of number of not white kittens = 6/8
To write the fraction in lowest form find the greatest common factor of numerator and the denominator. Divide the numerator and the denominator by the greatest common factor .
Now the greatest common factor of 6 and 8 is 2.
= 
=
