Answer:
396 miles / 22 gallons = 18 miles per gallon
468 miles / 18 miles = 26 gallons of gasoline
What I did is I took the number of miles and divided it by the number of gallons to find how many gallons of gasoline were used per mile. Then I took that number of miles and divided 468 by it because that's the number of gallons we are trying to find. We ended up with 26 gallons of gasoline for 468 miles.
Top One
The equation for the top one looks like it is
y = (5/3) * x
So for example (5/3) 15 = 25 which is y is shown to be in the table of values.
Varies directly
Middle Table
Stupid as the question may seem, the answer is varies inversely. As the number of parachutes goes down the price per shute goes up. Maybe it does make sense.
Varies inversely.
Last Table
This one at least makes sense. As the cost of making the parachute goes up, so does the selling price.
Varies directly.
I'll take it that it's implied that we're only subtracting 2 everyday, and only triple 4 once.
So, let's break this down.
Triple 4. This means to multiply by 3, or self-add 4 three times.
It should look like this:
4 + 4 + 4
or
4(3) or 4 • 3.
Let's go with the addition path, as it's easier to understand.
4 + 4 + 4. (Total of three 4's)
4 + 4 = 8 (Get rid of two 4's)
We are now left with one 4.
Add it to our current sum, 8.
8 + 4 = 12.
We now have 12 total.
However, since we're subtracting 2 EACH day, we'll have to divide 12 by 2 to find how many days until we reach zero.
12 / 2 = 6.
It will take 6 days for you to have zero.
I hope this helps!
Answer: 42650
Step-by-step explanation:
The tens place is behind the ones place.
The number in the tens place in 42653 is 5.
So to round to the nearest tens you have to change three to 0 because if the number in the ones place is 5 or more, then the number in the tens place would be 1 higher than it used to be while the number in the ones place turns to 0.
However if the number in the ones place is less than 5, then that's the only thing that changes, the ones place would change into a '0.'
Hope that helped!
