Hope this helps!

5/15. You add all the foods together so pasta meals plus seafood meals plus burgers 4+5+6=15. 15 is your total and since seafood is what we want we take that five and it’s 5/15 so sea food out of total food. Reduced it is 1/3

O c.
y= 0

y=-5

Answers

Answer:

x = 0

Step-by-step explanation:

ln x + 5, similarily to ln x, has no right asymptote, because it goes to infinity (very slowly), but also any line y=ax+b raises faster than ln x for positive a.

It has a left asymptote though - ln x deacreases very fast as x approaches 0, so it has a vertical asymptote of x = 0.

Greg has a storage container in the shape of a
rectangular prism that has a volume of 360 cubic
feet. The container's base measures 8 feet long and
9 feet wide. What is the height of the storage
container, in feet?

Answers

Answer:

The answer is 5

Step-by-step explanation:

First you need to know the equation for volume which is: length×width×height

You have the length and the width which those are: l=8 and w=9

Multiply the length and width together: 8×9=72

Then divide 360÷72=5

Check your math: 8×9×5=360

Therefore, the correct answer is 5
