Answer:
c. 50kg = 50,000g
Step-by-step explanation:
We have to solve these following rule of three to see which of the following is a correct conversion of 50kg.
a)
Each kg has 1000g
So
1kg - 1000g
50kg - xg
x = 50*1000
x = 50,000g
Conversion a) is wrong
b)
Each kg has 1000000mg
So
1kg - 1000000g
50kg - x mg
x = 50*1000000
x = 50,000,000 mg
Conversion b) is wrong
c)
In a), we have already converted 50kg to g. We have verified that 50kg = 50,000g. So c. is correct
d)
In b), we have already converrted 50kg to mg. We have verified that 50kg = 50,000,000g. So d. is wrong
1. 13.75= 0.25b +0.50
-0.50 -0.50
13.25 = 0.25b; divide both sides by 0.25 to isolate b and you get:
53 = b
2. 10w + 4w = -84
Add like terms!
14w = -84; divide both sides by 14 to isolate w and you get:
w = -6
4.02 so around 4 dollars :) hope this helps
Answer:
1/13
Step-by-step explanation:
I'm assuming you need the probability of choosing a 7 when pulling one card from a standard deck of playing cards.
There are four 7's in a deck of 52 cards.
Probability = (number of desired outcomes)/(number of possible outcomes)
The number of desired outcomes is 4 because there are 4 chances of pulling a 7 from a deck when choosing one card.
The total number of possible outcomes is 52 because there are 52 different cards to choose from when choosing one card.
So the probability is
P(7) = 4/52
P(7) = 1/13
