You need to multiply the four numbers and then takeway
Answer:
B
Step-by-step explanation:
To answer this, we need to see the to see to the fact that they are both in the same unit before we can take the ratio.
Firstly, we know that 1 foot = 12 inches. 9 feet would this be 9 * 12 = 108 inches.
Now we are told to get the ratio of length of car to length of model.
This means 108:6 = 18:1
Answer:
y = 4
Step-by-step explanation:
The graph passes through the point (3, 4), which means that the value of the function is 4 when x=3.
Answer:
80m
Step-by-step explanation:
The height of giant redwood tree is 100m.
so half of it is 50m
The height of redwood tree is 30m+ 50m= 80m
Correct Answer:Second option
Solution:The given sequence is:
2.2, 6.6, 11, ...
If we observe the sequence it is an Arithmetic Sequence as the difference between two consecutive terms is the same.
6.6 - 2.2 = 4.4
11 - 6.6 = 4.4
First we find the general term for this sequence.
![a(n)= a_{1}+(n-1)d](https://tex.z-dn.net/?f=a%28n%29%3D%20a_%7B1%7D%2B%28n-1%29d%20)
![a_{1}=](https://tex.z-dn.net/?f=%20a_%7B1%7D%3D%20)
first term = 2.2
d = 4.4
So,
![a(n) = 2.2 +(n-1)*4.4 \\ \\ a(n) = 2.2 + 4.4n - 4.4 \\ \\ a(n) = 4.4n - 2.2](https://tex.z-dn.net/?f=a%28n%29%20%3D%202.2%20%2B%28n-1%29%2A4.4%20%5C%5C%20%20%5C%5C%20%0Aa%28n%29%20%3D%202.2%20%2B%204.4n%20-%204.4%20%5C%5C%20%20%5C%5C%20%0Aa%28n%29%20%3D%204.4n%20-%202.2)
This general term will be placed inside the summation sign with limits from 1 to 5 to give the sum of first 5 terms of the given sequence. So the correct answer is Second Option
