Answer:
Geometric sequence
common ratio
1/8 (or 0.125)
Step-by-step explanation:
To get to the next number we have the mulitply the one before by 1/8
Because we are multiplying each time it's a geometric sequence
Because it's a geometric sequence we have a common ratio
I wrote before that to get to the next number we have to multiply it by 1/8 so that's the common ratio
Answer:
b, c, d, e
Step-by-step explanation:
a) 18/24 = 75%
b) 18/20 = 90%
c) 36/40 = 90%
d) 54/60 = 90%
e) 81/90 = 90%
Answer:
In order to fulfill the mathematical expression you must add a negative to the right side.
Hence: -=-
<u><em>Answer:</em></u>
(c) 4.1 km
<u><em>Explanation:</em></u>
We are given that the height of the balloon is 4 km and that it is 1 km away from the station.
Setting up the diagram that describes the given scenario, we would end up with a right-angled triangle as the one shown in the attached image
<u>where:</u>
height of the balloon = 4 km represents one side of the triangle
distance between the base of the balloon and the station = 1 km represents the other side
distance between the balloon and the station is the length we want to find and it represents the hypotenuse of the triangle.
<u>To get the length of the hypotenuse, we will use the Pythagorean theorem</u>
<u>Substitute with the givens:</u>
= √17 ≈ 4.1 km
Hope this helps :)
