Hi, I’m Lena and I will be answering your question to the best of my ability. If you have any further questions after my answer, do not hesitate to ask me! ツ
♡ Let’s look at the main important thing(s) that will lead you in the correct path.
♥ The perimeter is the outside, it is <em>around</em> the figure. When you see those inner triangles, do not pay attention to them! They are just there to make your overthink the question.
♡ Let's solve!
♥ To begin, let's take LM. It already gives you half the segment, so all you need to do is double the number. 9*2=18.
♥ Now, let's take a look at NR. They already give you the segment as a whole, so you do not need to worry about it!
♥ Look at SR. You do the same thing as you did to LM, double the number. 8*2=16.
Now, we add all the numbers to get our final answer.
18+16+16=50.
Given:
The given expression is:
According to Kylie,
To find:
The correct statement for Kylie's explanation.
Solution:
We have,
According to the perfect square trinomial 
.
Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly.
Therefore, the correct option is C.
Answer:
x = -2
Step-by-step explanation:
x^a × x^b = x^(a+b)
Similarly,
(5/3)^(-5) × (5/3)^(-11) = (5/3)^(-5-11)
= (5/3)^(-16)
-16 = 8x
x = -2
Answer:
6.25%
Step-by-step explanation:
Percent error is calculated by taking the difference of measured value and correct value divided by correct value and multiplied by 100%.
Mathematically,
Percent error = (correct value - measured value)/correct value * 100%
_________________________________________________
in the problem given
measured value = 75 degrees Celsius
correct value = 80 degrees Celsius ( as given in reference book)
thus,
Percent error = (80 - 75)/80 * 100%
Percent error = (5/80 )* 100% = 6.25%
Percent error calculated by him is 6.25%.
Answer:
24
Step-by-step explanation:
let 'x' = number
x/2 - 2 = 10
add 2 to each side to get:
x/2 = 12
cross-multiply to get:
x = 24
