Answer:
z = (xy)/(x+y)
Step-by-step explanation:
Taking logarithms base 10, we have ...
x·log(2) = y·log(5) = z·log(10)
z = x·log(2) = y·log(5) . . . . . . . . log(10) = 1
__
Then z/x = log(2), and z/y = log(5), so ...
z/x +z/y = log(2) +log(5) = log(2·5) = 1
z = 1/(1/x +1/y) = 1/((x+y)/(xy))
z = (xy)/(x+y)
Answer:
Step-by-step explanation:
it's 12 by 10, 12 x 10 = 120. because it's a triangle, you divide 120 by 2.
120 / 2 = 60. therefore the area of the triangle is 60. I also don't know the unit im supposed to use. is it centimeters? inches? miles?
Answer:

Answer:
B. Side <em>a</em> is 7 inches long and side <em>b</em> is 6 inches long.
Step-by-step explanation:
Since the scale drawing is three times bigger than the actual object, divide both numbers by three to find the object size.
Side a:
21/3 = 7 inches
Side b:
18/3 = 6 inches
