Max's deck also has 40 blue cards, and for every 5 blue cards in his deck there are 9 red cards. His blue cards can be divided exactly into 8 groups (8 times 5 is 40), so he should also be able to divide his red cards into exactly 8 groups of 9 cards each. So there are 72 red cards in his deck (8 times 9 is 72).
Answer:
your work is hard
Step-by-step explanation:
The top answer. You can spin the top and get an A and spin the bottom and get 1,2 or 3. Same applies to B
In this question a vital information has been provided. This information can be used for determining the answer to the question that is asked. It is given that 120% of a certain number is 360 pound. The 100% value of the number needs to be determined.
Let us assume the number to be = x
Then
120x/100 = 360
12x/10 = 360
12x = 360 * 10
12x = 3600
x = 3600/12
= 300
Now we can say that the 100% of the number or the actual number is 300 pounds. I hope the problem is clear to you and you can understand the trick involved in the question.
Answer:
x=√2, x= -√2
Step-by-step explanation:
6x²+1=13
<em>Subtract 1 from both sides</em>
6x²+1-1=12-1
<em>Simplify</em>
6x²=12
Divide both sides by 6
6x²/3 = 12/6
<em>Simplify</em>
x²=2
<em>For x²= f(a) the solutions are x=√f(a), √-f(a)</em>
x=√2, x= -√2
