Answer:
x=20
Step-by-step explanation:
just use the pythagorean theorem!!
square 12 and 16 to get 144 and 256
add those together to get 400, and then just take the square root of 400 (which is 20)
this means that x=20!
hope this helps!! :)
Answer:
Their is 10% of males and females.
Step-by-step explanation:
Because if you subtract 50% and 40%you would get 10% that means their is more females.
If y varies directly with x, means that they can be modeled by a linear equation, lets choose a line with 0 y intercept, that is:
y = mx + b
y = mx
where m is the slope of the line, now we plug in the data we have:
y = mx
20/3 = m(30)
solving for m:
m = (20/3)(1/30)
m = 20/90
m = 2/9
so the line equation, or function modeling the y and x relationship is:
y = (2/9)x
Answer:
A. -1/8 x + 3/16
Step-by-step explanation:
Distribute -1/2 over the parentheses
-1/2 ( 1/4 x - 3/8 )
-1/2 (1/4 x) - 1/2 (-3/8 )
multiply fractions to simplify
-1/8 x + 3/16
A is correct
Answer:
If it is using pi as 3.14, it is 56.52.
If it is just the pi symbol, it is 18π.
Step-by-step explanation:
We do 9 x 3.14 = 28.26 and then you multiply that by 2 to get 56.52.
We do 9 x π = 9π. Then multiply by 2 to get 18π.
