Answer:
7 cm, 4.4 cm
Step-by-step explanation:
The side lengths can be found from the law of cosines. Each triangle has legs 3 cm and 5 cm. The angle between these will be 60° or 120°. Then the two sides of the parallelogram are ...
s = √(a² +b² -2ab·cos(C))
s = √(3² +5² -2·3·5·(±1/2)) = √(34 ±15) = {√49, √19}
The two side lengths are 7 cm and about 4.4 cm.
<h3>
You are correct. The answer is the second choice.</h3>
BC = JC by the single tickmarks shown
CD = CD because of the reflexive property
The angles between these two pairs of sides, that you've marked in the second answer choice, are needed to use SAS (side angle side).
See the diagram below. In the diagram, angle BCD (green) is between segments BC and CD. Also, angle JCD (blue) is between JC and CD.
The question demands that we find a fraction of a given quantity.
The 'of ' means multiplication.
So the total distance of the journey was

But they walked ¼ of the whole journey. We are supposed to find




Hence they walked 3.25 miles.
Answer:
19.5
Step-by-step explanation:
I'm presuming the scale factor's 1.75/1
14*1.75=21.5
21.5-2=19.5
1 ticket =.5
12=.42
25=.40
50=.5
120=.42
I would suggest that they constantly lower the rate per ticket as the number of tickets increases so for example
1t=.5/ticket
12t=.42/ticket
25t=.38/ticket
50t=.35/ticket
120t=.30/ticket
