Answer: 60
Step-by-step explanation:
Answer:
Every prism has as many faces, and edges, as its base has sides. Thus, a prism with an octagonal (eight sided) base has eight lateral faces, and eight lateral edges. Each lateral face meets two other lateral faces, as well as the two bases. As a consequence, each lateral face is a four sided polygon.
Time taken to practice dance on Monday = hours
In decimals it is 1.25 hours
Time taken to practice dance on Wednesday = = or in decimal form it is 2.125 hours
Time taken to practice dance on Friday = 2.6 hours
Now comparing all the values in hours that is 1.25 , 2.125 and 2.60 ,the closest number to 2 is 2.125
1.25 is 35 minutes less than 2.
2.60 is greater far and from 2.
And 2.125 is closest to 2.
Hence, she practiced closest to 2 hours on Wednesday.
Answer/Step-by-step explanation:
1. x*21 = 24*14 (intersecting chords theorem)
21x = 336
x = 336/21
x = 16
2. 27*x = 45² (secant-tangent rule)
27x = 2,025
x = 2,025/27
x = 75
3. (x + 5)*5 = (4 + 6)*6 (Intersecting secants theorem)
5x + 25 = (10)*6
5x + 25 = 60
5x = 60 - 25
5x = 35
x = 35/5
x = 7
4. (4x + 2)*8 = (5x + 1)*7
32x + 16 = 35x + 7
Collect like terms
32x - 35x = -16 + 7
-3x = -9
x = -9/-3
x = 3
