Given :
Lulu tells her little brother, Jack, that she is holding 20 coins, all of which are either dimes or quarters.
They have a value of $4.10. She says she will give him the coins if he can tell her how many of each she is holding.
To Find :
How many dimes and quarters in Lulu holding?
Solution :
4.10 dollar = 410 cents
Let, number of dimes and quarter are x and y.
So, x + y = 20 ...1)
Also, 10x + 25y = 410 ...2)
Putting value of 1) in equation 2), we get :
10x + 25( 20 - x ) = 410
10x + 500 - 25x = 410
15x = 90
x = 6
y = 14
Therefore, number of dimes and quarters are 6 and 14 respectively.
Hence, this is the required solution.
Answer:
combined like terms and then follow the order of operations.
Step-by-step explanation:
Answer:
5 degrees
Step-by-step explanation:
We are given that during a science experiment
The temperature of a solution in a beaker 15 degrees below zero
The temperature of solution in a beaker 2 was opposite of the temperature in beaker 1
We have to determine the temperature of beaker 2.
It mean temperature of beaker 1 solution=-5 degrees
According to question
Temperature of beaker 2 solution =5 degrees
Hence, the temperature of solution in a beaker 2=5 degrees
Answer:
0.99, 0.6, 1, 0.01, 0, 0.3 respectively
Step-by-step explanation:
This event is extremely likely but there will be some occasions when it does not occur. The correct match is 0.99
This event will occur more often than not. The correct match is 0.6
This event will always occur. The correct match is 1
This event is very unlikely, but it will occur once in a while in a long sequence of trials. The correct match is 0.01
This event is impossible. It can never occur. The correct match is 0
This event is reasonably likely, and will occur sometimes, but not most of the time. The correct match is 0.3
