"c" is the hypotenuse of the largest triangle, and "a" is that triangle's shortest side. Thus the ratio is
... (longest side)/(shortest side)
Since all the triangles in the figure are similar, to complete the proportion, you need to recognize the triangle that "a" is the longest side of, then find the shortest side of that triangle.
"a" is the longest side (hypotenuse) of the smallest triangle. The shortest side of that triangle is "r". So, your proportion is ...
... c/a = a/r
The appropriate choice is the 2nd one, ...
... r
Answer:
5..(b)
Step-by-step explanation:
Pythagoras theorem states that
Hypotenuse(squared)=opposite(squared)+ adjacent(squared)
hypotenuse=?,opposite=3,adjacent=4
hyp(squared)=3(squared)+4(squared)
hyp(squared)=9+16
hyp(squared)=25
find the square root of both sides
hypotenuse=5
Marisol biked a total of 71 miles. On the other hand, she biked about 10 more miles on Wednesday than on Thursday.
<h3>How to round numbers?</h3>
The general rule is to move the decimal number to its nearest tenth. For example, 5.6 should be rounded as 6 but 5.1 should be rounded as 5.
Now, let's round the distance covered by Marisol each day:
- Monday: 12.3 = 12
- Tuesday: 14.1 = 14
- Wednesday: 17.7= 18
- Thursday: 11.8 = 12
- Friday: 15.2 = 15
<h3>What distance did Marisol covered?</h3>
To know this just add the distance every day:
- 12 + 14 +18 + 12 + 15 = 71 miles
<h3>How much more did she bike on Wednesday than on Thursday?</h3>
Distance covered on Wednesday - distance covered on Thursday
Note: This question is incomplete; here is the missing information:
- Monday 12.3
- Tuesday 14.1
- Wednesday 17.7
- Thursday 11.8
- Friday 15.2
