Answer 1

Answer:

2√2

Step-by-step explanation:

< C = 180-15-45 = 120°

AC/sin 45° = AB/sin 120°

AC = 2√3 × sin 45° / sin 120°

= 2√3 × ½√2 / ½√3

= 2√2

Rory would finish first!
To find the amount of pages they read you divide the amount of pages by the time
140/5 = 28
200/7.5 = 26.6
To find how long it would take them you take the number of pages they need and divide it by there average amount of pages per hour
350/28 = 12.5 hrs
350/26.6 =13.2 hrs

Find the mean, median mode and range of: 75, 80, 60, 90, 85, 80, -7, 90, 70, 65

Answers

Answer:

Mean: 68.8.

Median: 77.5

Mode: 80, 90

Step-by-step explanation:

-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90 = 688. Then divide by 10 because there are 10 numbers.

-7 + 60 + 65 + 70 + 75 + 80 + 80 + 85 + 90 + 90

(75, 80) are the middle numbers, so add them both, then divide by 2.

80, 90 appear more than the other numbers.

Range is highest - lowest. 90 - (-7) = 97, or it could be 83. I don't know.

The mean is 68.8

The median is 77.5

The mode is 80 and 90

The range is 97

(adding more to this but since the question only asked for one answer this should be enough!)

Step-by-step explanation:

a : 59

b : 59

c : 121

d : 121

f : 59

g : 90

h : 59

j : 31

k : 31 (everything in bold is uncited knowledge from me doing this years ago :,)

m : 90

so g must = 90 because not only is it in a right triangle, but also the corner of the rectangle. this goes for hk, m and jf, they all must add up to 90.

given a = 59 we can also find d from this, as it must add up to 180.

then adding g [90] + a [59] we get 149, which we then subtract from 180 to get j.

we get 31 from that and can now subtract 90 from that to find f, which is also 59, so f=59.
