Can someone help me please? What is 6 times 6 plus 9 divided by 10 in the second power?

Mathematics

Dovator [93]3 years ago
5 0

First of all, it would be easier to write down this problem, wouldn't it? ;)

6 x 6 + 9 ÷ 10^2

According to PEMDAS, we will start off with the exponent part of the equation, since there are no parenthesis.

10^2 = 100

Now, we will multiply 6 x 6, which equals 36.

Then, you will divide 9 by 100, which makes 0.09. Now we can add 0.09 to 36 and see what we get as a final answer.

0.09 + 36 = 36.09

FINAL ANSWER --

36.09

At a local high school football game, twice the number of students attended as adults. If student tickets were $6.50, adult tick
lesantik [10]

Answer:

454

Step-by-step explanation:

set up a system of equation

let y be the number of students

let x be the number of adults

because there are twice the amount of students attended as adults, we can use y=2x as one equation

the other equation will be 6.5y+9x=4972 because this represents the total amount of money

plug 2x for y : 6.5(2x)+9x=4972 : x=226

plug 226 in for the first equation : y=2(226) : y=452

How do I find the answers to 17, 19, and 20?
Irina18 [472]

Answer:

17. 6

18. 18 (as shown)

19. 10/3 = 3 1/3

20. 20/3 = 6 2/3

Step-by-step explanation:

17. For this, you can subtract the given length GB=12 from the length you found for problem 18, BF=18. Doing that tells you FG = 18-12 = 6, as you have marked on the diagram.

19. As with median BF, the point G divides it into two parts that have the ratio 1:2. The distance from G to D is the shorter of the distances, so you have ...

... GD = (1/3) CD = (1/3)·10 = 10/3

... GD = 3 1/3

20. You can subtract GD from CD to get CG, or you can multiply CD by 2/3. The result is the same either way.

... CG = CD -GD = 10 -3 1/3

... CG = 6 2/3

_____

<em>Comment on centroid and median</em>

The centroid (G) divides each median into parts in the ratio 1:2. Hence the shorter of those parts is half the length of the longer one, or 1/3 the total length of the median.

The longer of the parts is double the length of the shorter one, or 2/3 the total length of the median.

Your marking of median BF seems to show an understanding of these relationships. (Total length: 18; length of parts: 6 and 12.)
