There are 13 diamonds in a regular deck of cards.
So the probability of picking a diamond card is 13/52.
Answer:
1. $132.24
2. $55.89
3. $1336.66
4. $258.19
5. $57.86
Step-by-step explanation:
Simply use this equation.
Substitute in our values, using No.1 as our example.
Cross multiply
922.575 = x100
Solve for x by dividing by 100.
x = 9.22575
Now add x to the initial value.
9.22575 + 123.01 = 132.23575
Round to the nearest hundredth for the answer.
$132.24
Answer:
1a) 1141/660
3/5 + 6/11 +7/12
find the LCM of the denominators
the LCM of 5,11,12 is 660
after finding the LCM divide it with the denominator.
after dividing 660 by 5 i get 132. So i need to multiply it with 3. Now, i got 396. Do the same with the rest of the numbers.
u will get smth like this: 396+360+385/660
and the final answer will be1141/660.
b) 71/40
c) 211/28
d) 103/20
