Answer:
3
Step-by-step explanation:
The tenths is the closest to the ones places.There is more than 4 so we can add 1 to the whole number and take off the extras,and there you have it!
Answer:
-5 and 17
Step-by-step explanation:
-5+17 = 12
-5*17 = 12
Answer:
4.432432 * 10^(13)
Step-by-step explanation:
We need to divide
(1.64 x10^(-24))
---------------------
(3.7 x10^(-38))
We can first divide (1.64/3.7)
0.4432432 * (10^(-24))
---------------------
(10^(-38))
Since the term consists of a division with the same base, we just need to subtract the exponents
0.4432432 * (10^(-24 - (-38)))
= 0.4432432 * 10^(-24 +38)
= 0.4432432 * 10^(14)
= 4.432432 * 10^(13)
9514 1404 393
Answer:
yes
Step-by-step explanation:
The tower is about 50.1 meters tall. The guidebook is correct.
__
The distance from the base of the tower to the angle vertex is ...
d1 = h/tan(46°)
d2 = d1 +50 = h/tan(27°)
Then the height of the tower is ...
h/tan(46°) +50 = h/tan(27°)
50 = h(cot(27°) - cot(46°))
h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692
h ≈ 50.1544 . . . meters
The tower is more than 50 meters high.
