Sarah gave the same answer when asked to round 4 7/8 to the nearest inch and half a inch. Explain why Sarah is correct.
Answers
u would round it up to 5 again for the nearest half inch because 7/8 is closer to 1 than 1/2 which brings it to 5

Answer:
140 deg
Step-by-step explanation:
The sum of the measures of the interior angles of an n-gon is
(n - 2)180
In a 9-gon, there are 9 sides, so n = 9.
The sum of the measures of the interior angles of a 9-gon is
(n - 2)180 =
= (9 - 2)(180)
= 7(180)
= 1260
A regular polygon has congruent interior angles. A 9-gon has 9 congruent interior angles. The measure of each interior angle is the sum of the measures of the interior angles divided by the number of angles.
1260/9 = 140
3x+4=2x-7x-9

Group everything together
When isolating the variable do the opposite operation and do it on both sides.
You'll see what I mean
So for this it's 3x+4 = 2x-7x-9. So on the side with the -9 group the two variables together. Now you have -5x.
3x+4=-5x-9.
Now just subtract four from the side with 3x, as we are isolating the variable, and subtract it also from the other side, follow the rule. Now you have 3x=-5x-13. Next do what I did with the 4 and ADD 5x to each side, now you have 8x = 13. Divide each side to isolate even further and get x = 13/8.
Your final answer is:
x = 1 5/8

Prime numbers are numbers that can only be divided by 1 and itself.
99 ÷ 3 = 33
33 ÷ 3 = 11
11 ÷ 11 = 1
1 x 3 x 3 x 11 = 99
3 and 11 are the prime factors of 99.
3² x 11 = 99
The required primefactorization of 99 is: 3 * 3 * 11.
To find the prime factorization of 99, we can follow these steps:
- Step 1: Divide the number by the smallest prime number, which is 2. However, 99 is not divisible by 2.
- Step 2: Divide the number by the next prime number, which is 3. 99 is divisible by 3.
99 ÷ 3 = 33
- Step 3: Now, we focus on the quotient, which is 33. We repeat the division process using prime numbers until we cannot divide further.
33 ÷ 3 = 11
- Step 4: The quotient is now 11. Since 11 is a prime number, we stop here.
Therefore, the prime factorization of 99 is: 3 * 3 * 11.

'f' of the frames are size 4 by 6, and cost 5.8
that means 20 - f frames are size 5 by 7, and cost 9.6
And the total is 80.8
So... we get:
5.8f + (20-f)9.6 = 80.8
