If you’re looking for the ratio:
75cm = 750mm
250:750
1:3
The answer is 1:3
<span>A set of data that is made of two paired variables is called bivariate data. This simply means 2 variables exist in the data. Both of them are usually linked to each other. As one variable changes value there is a proportionate change in the other value. However sometimes one value may remain constant while the other changes.</span>
For the answer to the questions above,
A) Parrots are following a Geometric Progression of 15% increase.
20(1.15), 20(1.15)², 20(1.15)³,
Function = 20(1.15)^n Where n is at the end of year, n =1, 2, 3, ..
Snakes are increasing by 4.
28, 32, 36,....
Function = 24 + 4n n = number of end year, n =1, 2, 3,...
<span>B) After 10 years: </span>
Parrot = 20(1.15)¹⁰ = 80.91115471
Snakes = 24 + 4(10) = 64
<span>C) After what time they are the same: </span>
We use trial and error:
Test: n 20(1.15^n) (24 + 4n)
1 23 28
2 26.45 32
<span> 3 30.41 36 </span>
4 34.98 40
5 40.23 44
6 46.26 48
7 53.20 52
8 61.18 56
9 70.36 60
After year 7, the Parrots increases far more.
<span>At year 7 they are roughly the same.</span>
-5.4 - (2.1 + 1.8)=-9.3
So I would say A. Thanks for asking your question today and have a good day on Brainly.com! :)
Answer:
Soft Tacos = 2
Burritos= 3
Step-by-step explanation:
You
3 x 2 = 6
18 - 6 = 12
12/4= 3
You spent 6$ on soft tacos and 12$ on burritos.
Your friend
2 x 2 = 4
10-4 = 6
6/2 = 3
Your friend spent 4$ on soft tacos and 6$ on burritos.
I hope I explained this well.
