Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole given a part and the percent.
Answer:
158 ribbons even half of one still counts.
Step-by-step explanation:
With inverse functions you just swap 'x' and 'y' and solve for 'y'.
Swap 'x' and 'y':
Add 7 to both sides:
Take the square root of both sides:
Answer:
The radius and height of the cylinder of maximum volume is 9 unit and 9 unit.
Step-by-step explanation:
Given that,
Radius = 9
According to figure,
Radius of cylinder = Radius of hemisphere
Center of cylinder base is also center of sphere.
Circular top of cylinder touching the top of hemisphere.
So, Height of cylinder = radius of hemisphere
Hence, The radius and height of the cylinder of maximum volume is 9 unit and 9 unit.
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.)
