Answer:</h3>
no
<h3>
Step-by-step explanation:</h3>
The triangles are only similar if B lies on AD and C lies on AE.
There is nothing in the given information indicating B lies on AD, or that C lies on AE. AB and BD are identified as separate segments, so don't necessarily lie on the same line. C is not identified as being anywhere in particular. "The figure shown" cannot be assumed to have any characteristics not specifically identified.

<em>Comment on the problem</em>
The answer depends somewhat on the context of the problem. If this comes from course material in which you are routinely asked to make assumptions about figures, then the correct answer here is probably "yes." If this comes from course material that expects you to exercise critical thinking and to make no assumptions about geometrical figures, then the answer here is definitely "no."
In my opinion, one of the main purposes of studying math is to learn critical thinking—to pay attention to given facts and any assumptions you need to make.
Answer:
429/7 kg or 61 2/7 kg
Step-by-step explanation:
I'll answer according to how I understand this problem, but I'm not sure this is correct.
"39 kg of rice is taken out of bag of rice. If 8/22 of the rice is left, what was the original weight of the rice in the bag?"
8/22 is a strange number to work with because it could have been given as 4/11. This is another reason I'm not too sure about this problem.
8/22 = 4/11
If 4/11 is left, then since 11/11 - 4/11 = 7/11, 7/11 of the rice remains.
7/11 x = 39
x = 39 × 11/7
x = 429/7
x = 61 2/7
You'll be solving:
-5t^2 + 20t + 15 = 3t + 3
5t^2 - 17t - 12 = 0
(t - 4)(5t + 3) = 0
t = 4 or t = -3/5, but let's assume t ≥ 0
Step-by-step explanation:
The box of 100 would be the better deal, considering buying 2 boxes of 50 would turn out to be $47.00
we are given
we know that
sum of all angles in any quadrilateral is 360
so, we can write it as
now, we can combine it
now, we can subtract both sides 258
so, this is FALSE..........Answer
