Answer:
x = 2
Step-by-step explanation:
3x + 4 - x = 8
Combine like terms
2x + 4 = 8
-4 from both sides
2x = 4
Divide by 2
x = 2
Answer:
I think it's A AND C. The diameter is just the radius multiplied by 2 at the end of the day.B is just wrong.
Answer:
14.2 years
Step-by-step explanation:
The multiplier of the population each year is 1 +5% = 1.05, so after n years the population has been multiplied by 1.05^n. You want to find the value of n that makes this expression equal to 2:
2 = 1.05^n
log(2) = n·log(1.05) . . . . . take logarithms
log(2)/log(1.05) = n ≈ 14.2
Growing at a rate of 5% per year, it will take about 14.2 years for the population to double.
Given:
.
To find:
The value of 
, rounding to the nearest thousandth.
Solution:
We know that,
On substituting , we get
Therefore, the value of is 0.646.
Considering that there are 1/2 cup of grapes and 2/3 of strawberries, we can add them together to get 1 and 1/6 cups. This is done by adding 3/6 + 4/6. I'm not sure if this is correct, since it's kind of easy for a high school problem... I hope this helps anyway :D
