The equation of an ellipse is x²/a² + y²/b² =1
a being the distance between the center & x intercept =7
b being the distance between the center & y intercept =5
Hence the equation of this ellipse is:
x²/49 + y²/25 =1
A number that has a negative sign in front of it, opposite from positive numbers, and below zero are all phrases that can describe negative numbers.

Answer:
Question 1
Volume of a cylinder = πr²h
r= radius h= height
diameter = 2*radius
diameter = 2* 4cm= 8cm
Volume = π × 4² × 11
= 553.14cm³
Answer:
12.5%
Step-by-step explanation:
In order to find the percentage the worker spent traveling, we can make us of the following ratio:

where number is how many hours he spent traveling, ammount is the total ammount of hours he reported and percent is the percentage we want to find. So we can solve the ratio for the percent, so we get:

now, we need to find the total amount of hours he spent traveling, this is gotten by adding the provided data:
6hrs+5hrs=11hrs
next we need to find the total amount of hours reported:
42hrs+46hrs=88hrs
so now we can substitute the data the problem provided us with:

which yields:
percent=12.5%
The only thing you should do is to divide 3,072 by 96 and the answer is 32.
So each of them should read 32 books :)))

have a nice day
