Answer:
153.94
Step-by-step explanation:
The formula for the area of a circle is
A =
If the diameter is 14 in the to get the radius all you have to do is divide it by 2 to get 7
R is radius
R = 7
plug in 7 for R in the equation
*
and you will get 153.94
Answer:
don't take my word for it
Step-by-step explanation:
1. J
2. E; exponent tells us how many times a number is used as a factor
3. L; if the GCF of a fraction is 1, then we cannot simplify it further.
4. C; Binary, means something w/ 2 components (0s and 1s in this case).
5. same as 12, crossed out
6. G
7. I
8. K
9. M
10. D; Divisible, by definition (no remainder/trailing digits e.g.: 1.<u>3495</u>).
11. A; Algebraic factor, it has common symbols used in algebra (e.g.: x)
12. crossed out
13. E; exponent, when we have , x is the number telling us this.
Answer:
10 and 19
Step-by-step explanation:
- In Algebra, an even number = 2x, because anything multiplied by 2 is even.
- There are two numbers in the question, I'll define the first one as 2x
- the other number is 1 less than twice of the first, so I'm going to define it <u>in algebra as 2(2x) - 1</u>, which is just 4x - 1
- the square of the first is
- the square of the second is
- add them together:
- this equation = 461, so
- simplify to
- I wont explain how to solve this here, since it is very complicated, if you don't know search up solving quadratics.
- the <u>solutions are 5 or -4.6</u>, it cannot be -4.6 since the question says positive, so the solution for <u>x = 5</u>
- substitute x into our equations for the two numbers in steps 1 and 2
- the <u>first number = 10, the second = 19</u>
