200 flying insects she catch for her project .
<u>Step-by-step explanation:</u>
We have , Heather had to collect insects for her biology project. She was able to collect 225 total insects. She collected 8 times as many insects that could fly as insects that couldn't fly. That means insects ratio of non-fly to fly is 1:8 .
There are a total of 225 insects , and for every one non fly insect there are 8 fly insects , Let x be the number of insects that can't fly so:
⇒
⇒ 
⇒ 
⇒ 
⇒ 
So , Number of fly insects = 8x = 8(25) = 200 . ∴ 200 flying insects she catch for her project .
2nd angle measures 50
90 is the total so all that was needed is to subtract 40 from 90
Angle 4 is congruent to Angle 7 because of the theorem If 2 parallel lines are cut by a transversal then corresponding angles are congruent (Thats the reason for statement 2). The 3rd statement is correct if the reason for it is not supplementary angles but is angle addition postulate (The reason for the third one is angle addition postulate). Lastly, the answer isnt transitive property but is substitution propert because you substitute angle 7 with angle 4 (last reason is substitution).
Hope I helped
Answer:
2/7
Step-by-step explanation:
This is basically asking how many 7/10 's fit in 1/5. Or 1/5 divided by 7/10.
1/5 divided by 7/10 is the same as 1/5 times the reciprocal, 10/7. Therefore it is 1/5*10/7, or 10/35.
That simplifies to 2/7.
The answer to this problem is 4
