Answer:14
Step-by-step explanation:
A nickel is 5 cents (20% of dollar)
and a quarter is 25 cents (25% of dollar)
We have given a pile of 42 coins worth of $4.90
Let x be the no nickels and
y be the no of quarter
therefore
x+y=42 -----1
+
=4.90 ---2
Solving 
we get
x=14 & y=28
Therefore no of nickels is 14 & no of quarters is 28
You draw a line and then a = and another line on another side
like this but bigger ––=––
Answer:
Initial Amount=1
Decay Factor=0.99987
Decay Rate=0.013%
Step-by-step explanation:
If P = 0.99987ᵃ
I. Initial amount
The initial amount is when a=0
P = 0.99987⁰ = 1
The Pressure at Sea Level=1
II. Decay factor
This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.
III. Decay Rate = 1-0.99987 = 0.00013
Expressed in Percentage = 0.013%
Answer:
B) 2
Below I wrote the steps on how I would find the answer.
Step-by-step explanation:
1. Yep, so basically cba = cbl + lba.
2. So you need to find x
3. So basically if you set up the equation 61x - 2 = 13x - 1 + 95
4. Then you can solve for x
5. X = 2
D.) 1.805 multiplied by 107
