Answer:
about 11.5 cm.
Step-by-step explanation:
I know the measurement of the other leg is about 11.5 cm. I know because I used the Pythagorean theorem.
a^2+b^2=c^2.
"a" and "b" are the values of the legs of the triangle, while "c" is the measure of the hypotenuse. We know that 8cm is the measure of one of the legs, and 14 cm is a measure of the hypotenuse.
8^2+b^2=14^2 simplified: 64+b^2=196
Then, I subtracted 64 on both sides, so I would have "b" by itself.
b^2=132
Next, I found the square root of both b^2 and 132, so I would find the true value of "b."
b=11.4891252931
So, the measure of the other leg rounded to the nearest tenth is about 11.5.
Answer:
k=10
Step-by-step explanation:
4k + 12= 52
minus 12 on both sides
4k=40
now divide by 4
k=10
First you ask yourself, can 8 go into 1? The answer is no. Can 8 go into 12? Yes, 1 time. So you put 1 on top of the 2 and subtract 8 from 12. That gives you 4. Then you pull down the 8 from 128 and ask how many times can 8 go into 48? The answer is 6. So your answer is 16. Hope I helped!
To convert from decimal to percent, just multiply the decimal value by 100. In this example we have: 0.768 × 100 = 76.8%
The ease way:
1) Move the decimal point two places to the right: 0.768 → 7.68 → 76.8.
2) Add a % sign: 76.8%
"<u>Answer: 76.8%"</u>
Hope this helps!
Thanks!
