Mathematics
1 answer:
enot [183]3 years ago
4 0

Answer:

5.66 units

Step-by-step explanation:

A's per our discussion, x is a leg of right triangle.

Therefore, by Pythagoras theorem:

x =  \sqrt{ {9}^{2}  -  {7}^{2} }  \\  =  \sqrt{81 - 49}  \\  =  \sqrt{32}

x =  \sqrt{ {16}^{2}  -  {12}^{2} }  \\  =  \sqrt{256 - 144}  \\  =  \sqrt{112}

The ratio of boys to girls in a class is 5:3. There are 32 students in the class. How many students are boys?
alina1380 [7]
Class ratio of girls to boys is 3:5
So there are 3 girls and 5 boys in 8 students
If there are 32 students, then 3/(3+5) * 32 = 12 girls, and 5/(3+5) * 32 = 20 boys

Need help ASAP <br> Thankss + BRAINLIST only for correct answer
Murrr4er [49]

Answer:

(2, 0)

Step-by-step explanation:

Given the simultaneous equation

2x-y = 4

3x+y = 6

Add both equation

2x+3x = 4 + 6

5x = 10

x = 10/5

x = 2

Substitute x = 2 into equation 1

From1 ;

2x-y = 4

2(2) - y = 4

4 - y = 4

y = 4-4

y = 0

Hence the solution to the system of equation is (2, 0)

Determine if each sequence is arithmetic, geometric, or neither.
Len [333]

9514 1404 393

Answer:

  • geometric
  • arithmetic
  • neither (Fibonacci sequence)

Step-by-step explanation:

If ratios are the same, it is geometric:

  8/4 = 16/8 = ... = 2

If differences are the same, it is arithmetic:

  -4-(-8) = 0 -(-4) = ... = 4

If neither is the case, it is neither:

  3-2 ≠ 5 -3

  3/2 ≠ 5/3

In this last sequence we see that differences equal the previous term. This is characteristic of the Fibonacci sequence, which sees wide use in Nature, and has a relationship to the Golden Ratio. (The ratios of successive terms approach the golden ratio (1+√5)/2 ≈ 1.618.)

HAAALP.... jk but it would be appreciated if you answer this geometry question. ._.
erica [24]

Answer:

33 units²

Step-by-step explanation:

Setting up an equation to find the area of given kite:

Area of the kite = \mathrm{\frac{(2ft+9ft)\times(3ft+3ft)}2}

Area of the kite = \mathrm{\frac{11ft\times6ft}{2}}

Area of the kite = \mathrm{\frac{66ft^2}^2}

Area of the kite = \mathrm{33\;ft^2}

Therefore, the area of our given kite is 33 square feet
