Answer:
150 grams
Step-by-step explanation:
The weight of the full jar of honey is equivalent to x + y, where x is equal to the weight of honey and y is equal to the weight of the jar.
x+y = 750
2x/3+y = 550
You can solve for y in the first equation and get:
y = 750-x
Plug that in to the second equation and you get:
-x/3+750 = 550
Subtract 750 from both sides:
-x/3 = -200
Multiple -3 on both sides:
x = 600 grams
The weight of the jar is 750-600 or 150
One fleece jacket is made with 20 bottles. That means we have to divide the 280 bottles by 20 to determine the number of jackets.
280/20=14.
14 fleeces can be made with 280 bottles.
When the order of something happens it is a permutation.
There are a total of 52 cards and you want to pick 2 different cards.
The equation for this is:
52! / (52 - 2!)
Simplified becomes 52! / 50!
Answer = 2,652 ways.
Answer:
Step-by-step explanation:
Ok so to find constant of proportionality, you need to find K.
X would be gallons and y is cost.
To find k you need to do k=y/x
k=17.50/5
k=3.5
That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.
k=35/10
k=3.5
k=52.50/15
k=3.5
For all of those 3.5 was constant.
Because they are constant, that means the data in the graph is a proportion.
An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.
k=52.50/16
k=3.28
That be different from the other 3.5's meaning its not proportional. But that's just an example.

Answer:
Step-by-step explanation:
So we are assuming only the times listed count toward telling us how long the game was, so you just add the three numbers together. 155, 175 and 30
