45 45 90 triangle
legs are x and hypotonuse=x√2
10=furst x
10=x
hypotonuse=10√2
that hypotonuse is the leg of the other triangle
the hypotonuse is √2 times that
10√2=x of bigger triangle
hypotonuse=x√2=10√2 times √2=10*2=20
answer is 20 units
Answer:
1.97 ounces
Step-by-step explanation:
-The exponential decay function is given by the formula:
Given that the half-life is 4 days, we can substitute in the formula to solve the rate of decay for a single half-life:
#Since, 1 week has 7 days, 3 weeks is a 21-day period, thus, t=21.
#We substitute and solve for the amount remaining after 21days of decay:
Hence, the amount remaining after 3 weeks of decays is approximately 1.97 ounces
<span>P: y + z = 6
Q: 8y + 7z = 1
A. This makes y = -8Y which will eliminate the "y"'s when the equations are added.

Step-by-step explanation: You multiply $85 by .2 to get this answer.
Answer:
1200
Explanation:
Order does not matter, if we said xyz order, it would still not make a difference if it was zyx or yzx hence we use the combination formula:
nCr = n! / r! * (n - r)!
where n= total number of items
r= number of items chosen at a time
Combinations are used when the order of events do not matter in calculating the outcome.
We calculate using the formula:
(30×20×12)÷3!=1200
There are therefore 1200 ways for the three distinct items to not be in same row or column
