Answer:
Step-by-step explanation:
Triangle ABC is a 45-45-90 right triangle. That means that segment BC also measures 10.
The big triangle as a whole is a 30-60-90. The side length across from the 30 degree angle is 10, so the whole length of BD is 10√3. However, since we already have the length of BC as 10, then segment CD measures
10√3 -10 which is 7.32
Answer:
10,93,500.
Step-by-step explanation:
On first February total number of rabbits were 500.
Now it is given that after each month rabbit population will become triple of initial.
So, after one month rabbits will become 3×500.
After two months they will become
×500.
Thus , after m months total number of rabbits will become
×500.
Now,
On August 1 , 7 months will get passed from February 1 so putting m = 7 in the equation we get ,
Total number of rabbits =
×500 = 10,93,500.
Answer:
6%.
Step-by-step explanation:
We have been given that Tammy deposited $520 in the bank account that earns simple interest every year after 5 years she had earned $156.
To find the interest rate we will use simple interest formula.

I= Interest.
P= Principal amount.
r=Annual interest rate (in decimal form).
T= Time in years.
We have been given that I=156, T=5, P=520
Upon substituting our values in above formula we will get,




Let us multiply 0.06 by 100 to convert annual interest rate in percentage.

Therefore, the annual interest rate was 6%.
I=prt
i=2000 X .04 X 7
i = 560
So you earned 560 after 7 years, plus your 2000 you started with
You can get C
Answer:
That is true.
Step-by-step explanation:
A supplementary angle equals 180 degrees and and a right angle is 90, so 90+90=180
