Answer:

Step-by-step explanation:
The computation of the thickness of tire rubber for every lost 1,000 driven is shown below:
Data provided in the question
Inches of tread = 
In case of replaced = 
Based on the above information
Now in 40,000 miles, the ratio is

And for every 1,000 miles driven, the thickness is

hence, the thickness of tire rubber is 
We have to realize a simple rule of three
if 1 cup of corn------------------------- > 7.87 g of fat
2.5 cup--------------------------- X
X=2.5*7.87=19.675 gr
the answer is 19.675 grams of fat in 2.5 cup of corn
Answer: 61 children attended the musical last night.
Step-by-step explanation:
Let x represent the number of children that attended the musical last night.
Let y represent the number of adults that attended the musical last night.
The musical charges $3.50 for children's tickets and $5.00 for adults tickets. If the tickets sales totaled $823.50. It means that
3.5x + 5y = 823.5- - - - - - - - - - 1
Last night, twice as many adults attended the musical than children. It means that
y = 2x
Substituting y = 2x into equation 1, it becomes
3.5x + 5 × 2x = 823.5
3.5x + 10x = 823.5
13.5x = 823.5
x = 823.5/13.5
x = 61
y = 2x = 2 × 61
y = 122
Answer:
190.9 in³
Step-by-step explanation:
Whenever one is asked to find how much(quantity of something) a certain container can hold,all you need to understand is that you are been asked about the volume of that container
We all know that the volume of a sphere is 4/3 × 22/7 × r³
And since we are dealing with a container in the shape of half a sphere,the volume of that container will now be volume of a sphere divided by 2
If the formula that was given initially was divided by 2,the new formula will look like this:
4/6 × 22/7 × r³
And we have the diameter but not the radius and we know that to find the radius, all we need to do is to divide the diameter by 2
That is 9/2 = 4.5
Putting the values in the formula,we can now derive the volume of that sphere
4/6 × 22/7 × 4.5³
= 190.9 in³ of soil
