Step-by-step explanation:
Y can be repeated but X can't
Answer:
ITS A
Step-by-step explanation:
Answer:
4 feet
Step-by-step explanation:
see the attached figure with letter to better understand the problem
we know that
A board is half way up each ladder
so
point B is the midpoint segment AC and point F is the midpoint segment AG
Than means
AB=AC/2 -----> AB=10/2=5 units
BF is parallel to segment CG ----> by Triangle midpoint segment theorem
step 1
In the right triangle ABD
Find the length side AD
Applying Pythagorean Theorem
solve for AD
step 2
Find the length of segment DE (h)
Remember that
If two triangles are similar, then the ratio of its corresponding sides is proportional
In this problem
Triangles ABD and ACE are similar by AA Similarity Theorem
so
substitute the given values
----> by segment addition postulate
substitute
solve for DE
therefore
The distance from the bucket to the ground is 4 feet
Initial amount, .
Final amount, .
Time taken, t = 6:00 - 2:00 = 4 hour.
We know,
Therefore, the half-life of the isotope is 1.024 hours.
Hence, this is the required solution.
Well a flat line equals 180 so you use the angle of a and try to find the other side of the angle, so you you do 180 subtracted by 125 which you get 55. Since B is parallel to the angle, the answer is 55 degrees.
