The simplest way to think of this is a ratio. In the original 7 cards used for demonstration, 4 are blue. You can write it like this:
Since there are 84 total cards, and you need to find how many total blue cards there are, you can compare the total of the sample to the complete total, and then solve for an x value of total blue cards.
=
You can solve using cross multiplication. 84*4=336. 7*x=336.
x=48
Compound Interest Formula:
A = P(1 + r/n)^(nt)
A= Accumulated amount with interest P= principal= $1000
R= annual interest rate (decimal)= 0.05
N= # times compounded per year= 12
T= # of years= 10
A= 1000(1 + 0.05/12)^(12*10)
divide inside parentheses first
A= 1000(1 + 0.0041666667)^ (12*10)
add inside parentheses
A= 1000(1.0041666667)^ (12*10)
multiply exponents
A= 1000(1.0041666667)^120
multiply parentheses by exponents
A= 1000(1.6470095043)
multiply last two numbers
A= $1,647.01 amount after 10 years
ANSWER:
D) $1647.01 total after 10 years
Hope this helps! :)
I believe that the answer is D. because 270+90=360, meaning a full turn.
Let me know if this helps! Brainliest is always appreciated!
Answer:
D
Step-by-step explanation:
A proportional relationship is one where the "proportion" of every x to every y is the same.
For example, if you have x=1 y=2 and x=2 y=4, you know they're proportional because 1/2 = 2/4.
The only table that fits this requirement is D, because
1/-8 = 3/-24 = 4/-32 = 6/-48
All the ratios of every x to every y are equal to -1/8!
