Answer:
45
Step-by-step explanation:
The n th term of a GP is
= a
where a is the first term and r the common ratio
Given a₂ = 6 and a₅ = 48, then
ar = 6 → (1)
a
= 48 → (2)
Divide (2) by (1)
=
, that is
r³ = 8 ( take the cube root of both sides )
r =
= 2
Substitute r = 2 into (1)
2a = 6 ( divide both sides by 2 )
a = 3
Thus
3, 6, 12, 24 ← are the first 4 terms
3 + 6 + 12 + 24 = 45 ← sum of first 4 terms
Answer:
9 batches
Step-by-step explanation:
(Found the full problem online)
1 batch : 4 liters of orange juice and 5 liters of soda water
How do we get from 4 and 5 to 36 and 45? For both we multiply by 9.
4 * 9 = 36
5 * 9 = 45
Therefore, they would be able to make 9 batches.
Hope this helps, please mark brainliest if possible :)
<h2>Addition</h2><h3>Concept</h3>
Add units together in order to reach a sum.
<h3>Utilization</h3>
In this problem, you are told to find the probability (or %) that someone owns either a dog, OR a cat. If they own both - then they do in fact own a dog or cat. So the formula is:
dog owners % + cat owners % + both owners %
Aka,

<h3>Answer</h3>
The answer is 46% of people own either a cat or a dog, because 23% + 18% + 5% is 46%.
