Answer:
Step-by-step explanation:
We can use the relationship between a radius and a diameter to find which circle has a greater area without calculating it.
We know that the diameter is twice the size of the radius.
- The diameter is the distance across the circle at the center
- The radius is the distance from the center of a circle to the edge
Using this, we can find the radius of a circle that has a diameter of 6.
Since the diameter is twice the radius, the radius will be half the diameter.
Since the diameter is 6, the radius is 3.
Circle areas can be calculated with the following formula, where r is the radius:
Using this, we know that a higher value of r will get us a greater area. Therefore, we know that the greater value (3 or 4) will get us the greater area.
Since 4 is greater than 3, we know that the circle with the radius of 4 (Ava’s) will have a greater area.
Hope this helped!
The answer to you’re question is 5 1/2 multiplied by 5 1/3. I submitted a photo showing how to put the answer.
Im guessing that your teacher wants you to apply the fact that no matter what order your numbers are in when adding or multiplying your outcome will be the same. So one multiplication fact is 16*147=2352 . Also if you multiply a negative times a negative you will get a positive number so -147*-16=2352 .
I hope this helps a lil:)
add 4 each time
the nth term is a_n or f(n)
the next term after that is a_{n+1} or f(n+1)
so each term is 4 more than previous
basically
a_{n+1}=4+a_n or
f(n+1)=4+f(n)
same thing
Answer:
a and c are the correct answers

Step-by-step explanation:
simplify each equation and look for ones which solve to a simple numeric equality:
First equation solves to -3/7=-18/42...take a 6 from 18 and 42, and you get -3/7. -3/7=-3/7 which is true - that means that, no matter what value is inserted for x, a true equation will result = infinite number of solutions
Second equation simplifies to 3x=-30. Nope
Third equation simplifies to -18=-18 = infinite number of solutions
Fourth eq: 5=-7/2 = No solution
5th eq: 6.2x=-3.5-16.2 = nope
