Answer:
according to my calculations he will be 69.6942069420 inches
Step-by-step explanation:
5 pounds = 80 ounces
80 days = 80/7 weeks = 11 weeks and 3 days, about 11 weeks
.55 when rounded up but this is the actual answer: 0.548461538461538
What do I need to find?
Your answer is correct.
What information do I need to use?
100% = 240 miles, she has already driven 15% of 240, so she has driven x miles.
How will I use the information?
Set up a proportion. If she has already driven 15% out of 100% of the distance, then you should write 
for the first fraction. This is proportional to 
. This means that 
. Wait, but this is confusing. How on Earth do we solve it? Let's take a closer look. If 
is supposed to equal 15/100, then this means that x/240 divided by 15/100 should give us the answer. So, even though it looks complicated, all you have to do is cross multiply like this:
Now isolate x:
So x = 36, which means she has already driven 36 out of 240 miles. Lucia still has to drive 204 miles to reach her destination.
1.) In this case, 56 = 100% and 25% of the sandwiches were tuna. This means that 75% of the sandwiches were not. If 
and you use the same method above, x is equal to 14. If 14 is 25% then that means the other 75% = 14 * 3. So 42 sandwiches were not tuna.
2.) 
--> 
---> 
He still has $270 left to pay.
Answer:
Slope = 0
slope is the same as gradient, so you will use the formula
M = y2 - y1 / x2 - x1 in this case (2,2) and (-1.2)
the first 2,is x1.then the other 2 in the first coordinate is y1 , for the last coordinate -1 is x2 and 2 is y2, use the formula I gave you , you will see that the answer is 0
