Answer:
5/14
Step-by-step explanation:
The total number of cards is 8
There are 5 blue cards
P(1st card is blue) = blue/total = 5/8
We take away a blue card
The total number of cards is 7
There are 4 blue cards
P(2nd card is blue) = blue/total = 4/7
The probability of blue blue is P(blue blue ) =
P(1st card is blue)*P(2nd card is blue) =
5/8* 4/7
20/56
We can divide the top and bottom by 4
5/14
Divide each term in
3x=27 by 3.3x3=27/3
Reduce the expression by cancelling the common factors.
Cancel the common factor.
3x3=27/3
Divide
x by 1.x =27 /3
Divide
27 by 3.x=9
Divide each term by 3 and simplify. hope this helps :)
-16 and -3
I just used 24 and 2, adding &/or subtracting to opposite sides until I got 16*3=48, whether they be positive or negative.
Add -16 and -3 together and you get -19.
Hope this helps you! :)
Here is the completed table:
Hours Weeks
168 1
1008 6
840 5
<h3>How to complete the table? </h3>
The mathematical operation that would be used to determine the missing values are division and multiplication. In order to convert hours to weeks, divide by 168 hours. To convert weeks to hours, multiply by 168.
1008 hours to weeks = 1008 / 168 = 6 weeks
5 weeks to hours = 5 x 168 = 840 hours

Answer:
h=24
Step-by-step explanation: In order to solve this we have to apply the Pythagorean Therom which states a^2+b^2=c^2. c^2 being the the hypotenuse. First we have to plug in the values so the new equation is a^2+7^2=25^2. Now we simplify to get a^2+49=625. We can now subtract 49 from both sides to get a^2=576. The final step is to square it to get a=24. So h=24
