128 degrees.
An angle's supplement, when added to the original angle, will form a straight (180 degree) angle.
Step-by-step explanation:
23. area of rect,r = 11 x 3.5 = 38.5cmsq
area of tri, t = 6 x3.5/2 = 10.5 cmsq
area of shaded region, sr = r-t
=> sr = 38.5- 10.5 = 28.5cmsq
24. area of square, s = 10x10 = 100mmsq
area of circle, c = pi x 5^2 = 78.5mmsq
area of shaded region, sr = s - c
=> sr = 100- 78.5 = 22.5mmsq
25. area of circle, c = pi x 6^2 = 113.04insq
area of tri, t = 6x12/2 = 36insq
area of shaded region, sr = c - t
=> sr = 113.04 - 36 = 77.04insq
Answer:
n = 12.546
Step-by-step explanation:
to find the value of n we need to transpose
n ÷ 102 = 0.123
n = 0.123 × 102
n = 12.546
Answer:
33.2%
Step-by-step explanation:
Calculate the z-scores.
z = (x − μ) / σ
z₁ = (82 − 100) / 15
z₁ = -1.2
z₂ = (98 − 100) / 15
z₂ = -0.133
Use a chart or calculate to find the probability.
P(-1.2 < Z < -0.133) = P(Z < -0.133) − P(Z < -1.2)
P(-1.2 < Z < -0.133) = 0.4470 − 0.1151
P(-1.2 < Z < -0.133) = 0.3319
Rounded to the nearest tenth, the percentage is 33.2%.
Answer:
The number of books in the owner's office are 4.
Step-by-step explanation:
It is given that the book store had a new bookshelf that could hold 62 books the owner put 5 books on each of the shelves and the rest back in his office.
Now, let us assume the there are 'n' number of total books that the owner have with him;
=> total books = n
and the total books the shelf could hold is;
=> total books the shelf could hold = 62
Further, it is provided that the owner put 5 books on each of the shelves and the rest back in his office;
=> n = 62/5
=> n = 12.4
Therefore, the number of books in the owner's office are 4.
