Find the total number of cards in a deck. Count all the # 3’s total cards/#3 cards
Count all the clubs total card/ clubs
Not sure if you are counting 3’s & clubs together. If you are, total cards/ both
So all you have to do is count & then divide to get the probability.
12/50 is the probability of rolling a 3
12/50= He has a 24% chance of rolling a three
False in a triangle 2 sides are the same and one is different
Answer:
11.)
We can let the scores we don't know by x, and we know that tokay had 14 more points than Lodi. This can be shown as the following:
x + (x+14) = 162
2x+14=162
162-14= 148
148/2 = 74
Therefore Lodi scored 74 points.
12.)
We can substitute the prices we don't know by x and have the following:
4x+x=6.50
5x=6.50
6.50/5= 1.3
4x1.3= 5.2
Therefore the sandwich cost $5.20 and the drink costs $1.30
We have an equation: 250/?= 50/100
Cross multiply:
50*?= 250*100
⇒ ?= 250*100/50= 500
The number is 500~
We have another equation: ?/500= 80/100
Cross multiply:
100*?= 80*500
⇒?= 80*500/100= 400
80% of 500 is 400~
