We can use the Pythagorean theorem to solve for the perimeter of the kite.

a² + b² = c²

3² + 4² = UV²

9 + 16 = UV²

25 = UV²

√25 = √UV²

5 = UV

In the kite, adjacent sides are the same so UV = VW

3² + 9² = UX²

9 + 81 = UX²

90 = UX²

√90 = √UX²

9.49 ≈ UX or 3√10 ≈ UX

Now, add to find the perimeter.

5 + 5 + 9.49 + 9.49 or 5 + 5 + 3√10 + 3√10

28.98 or 10 + 6√10

Therefore, the perimeter is approximately 28.98 or 10 + 6√10

Best of Luck!

21 Last year Chelsea and Sonya took 236 pictures during Thanksgiving. This year Chelsea and Sonya each took the same amount of p

Leokris [45]

Let 'c' represent the number of pictures Chelsea took.

Let 's' represent the number of pictures Sonya took.

For last year's Thanksgiving, c + s = 236

For this year's Thanksgiving, let 'x' represent the number of photos taken in total. x = c + s, where c and s are two integers that are the same (c = s).

And we know that for both years, c + s + x = 500.

As we know that c + s is already 236 from last year, we can remove c + s from the equation in bold and replace it with 236 instead.

236 + x = 500.

Now we have to isolate the x term.

x = 500 - 236

x = 264.

We know that x = c + s, where c and s are the same, so we can just use one of the variables and double it (so you either get 2c or 2s - it doesn't matter which one you pick because they're both the same).

2c = 264

c = 132

c = s

s = 132.

Both took 132 pictures this year.

What is x? 6(x+4)+3x-2

valina [46]

That is impossible to answer because this is an expression. you can only solve for x in equations

A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chess

maxonik [38]

Answer:

Total weight of the wheat placed on 45th square will be = $1.26\times 10^{6}tons$

Step-by-step explanation:

King rewarded the inventor of chess by giving grain of wheat on every square of the chess board. He places one grain of wheat on first square, 2 on second, 4 on 3rd, 8 on 4th and so on.

In fact he places grains of wheat in a progression S = 1, 2, 4, 8, 16.........n terms where value of n is 64.

We can rewrite the progression as S = 2°, 2, 2², 2³,.........n terms (n = 64)

In a geometric progression we know the nth term = $a(r^{n-1})$
