Alice spends $3 per day, so for in a week and upto 5 weeks, Alice spend =$3*5*5 = $75
Betty spends $ 25 every 2 weeks, so for 5 weeks , she spends= 25+25+12.5
= $62.5
Cindy spends $ 75 per month, and on an average there are less then 5 weeks in a month . SO for 5 week, it must be greater than $75 .
So the order is
Cindy>Alice>Betty
Answer:
Step-by-step explanation:
I find it hard to believe that you were asked to find the solution to a cubic by any other method than graphing it, which I have given below. Not only that, the numbers are very awkward.
The best you could do I think is equate the two equations after you have looked at the graph.
The x value must satisfy
0.5(x - 4) = 2x^3 - 2x - 3
0.5x - 2 = 2x^3 - 2x - 3
2x^3 + 0.5x - 2x - 3 +2 = 0
3x^3 - 1.5x - 1 = 0
from which you can get y
My calculator gives the solution as
x = 0.5
y = - 1.75
I have corrected the mistake I made doing this. The answer is now correct. The graph shows the original two equations which agrees with the combined equation given above.
Answer:
The product is 3^16
Step-by-step explanation:
When you multiply two numbers with the same base, you simply add the exponents.
9 + 7 = 16
Answer:
The triangles are not similar.
Step-by-step explanation:
First, what's all the information we know?
We know we're trying to prove that triangle BAC is similar to triangle DEC.
We know AC=12 and EC =12 (proving 1 side equal).
We know angle BCA and angle DCE or equal.
However, we do not know any information further than this, and there is no postulate/theorem for AS. Therefore, the triangles are not similar.
