The answer is $240.
If you round each amount to the nearest ten you get $130.00, $60.00, and 50.00. When you add all of those together you get an estimated amount of $240.
Answer: 
Step-by-step explanation:
The resultant can be calculated using triangular law of vector addition as :
The answer is
q + d = 12
0.25q + 0.10d = 2.40
q - the number of quarters
d - the number of dimes
You have 12 <span>coins, all quarters and dimes:
q + d = 12
The value of 1 quarter is $0.25.
The value of 1 dime is $0.10.
Therefore, if you want to pay </span>$2.40 you will have q quarters of value $0.25(0.25q) and d dimes of value $0.10d (0.10d).
The second equation is:
0.25q + 0.10d = 2.40
Ok here is how you do this:
you need to replace y with 20 and then solve to find x, i.e. solve this equation
20=2/5x
1. Simplify 2/5x to 2x/5
20=2x/5
2. Multiply both sides by 5
20 * 5=2x
3. Simplify 20 * 5 to 100
100=2x
4. Divide both sides by 2
100/2=x
5. Simplify 100/2 to 50
50=x
6. Switch sides
x=50
so your answer is B. 50

<span>Two events are said to be independent if the probability that one event occurs in no way affects the probability of the other event occurring.
Given that </span><span>Marco has a bag of red, blue, and green tiles.
The set of events that can be considered independent are:
</span>1.) <span>A tile is drawn and replaced, and then a second tile is drawn.
and
2.) </span><span>Two tiles are drawn at the same time.</span>
