Answer:

x = 12

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2 +b^2 =c^2 where a and b are the legs and c is the hypotenuse

9^2 +x^2 = 15^2

81 +x^2 = 225

Subtract 81 from each side

81-81 +x^2 = 225-81

x^2 = 144

Take the square root of each side

sqrt(x^2) = sqrt(144)

x = 12

Answer:

$\frac{20y^{2} a^{2} }{41bx^{3} }$

Step-by-step explanation:

1) Flip the second fraction and change the operation to multiplication:

$\frac{5x^{2}y^{3} }{2a^{5}b^{4} } * \frac{8a^{7}b^{3} }{41x^{5}y }$

2) Cross cancel factors:

$\frac{5y^{2} }{2b } * \frac{8a^{2} }{41x^{3} }$

3) Multiply:

$\frac{40y^{2} a^{2} }{82bx^{3} }$

4) Simplify:

$\frac{20y^{2} a^{2} }{41bx^{3} }$

The volume of a rectangular pyramid

Given a rectangular pyramid of width W, length L, and Height H, the volume is

$V=\frac{\text{WLH}}{3}$

We have to assume the pyramid given in the question has a square shape of length and width of L=34.5 feet and W = 34.5 feet, and a height of H=55 feet, thus the volume is:

$V=\frac{\text{34.5}\cdot34.5\cdot55}{3}=21,821.25ft^3$

1/4+4x/5=31/15 please show your work.

Novosadov [1.4K]

Answer: x = 109/48

Step-by-step explanation:

1. Simplify 4 x x/5 to 4x/5

1/4 + 4x/5 = 31 15

2. Subtract 1/4 from both sides

4x/5 = 31/15 - 1/4

3. Simplify 31/15 - 1/4 to 109/60

4x/5 = 109/60

4. Multiply 1both sides by 5

4x = 109/60 x 5

5. Simplify 109/60 x 5 to 545/60

4x = 545/60

6. Simplify 545/60 to 109/12

4x = 109/12

7. Divide both sides by 4

x = 109/12/4

8. Simplify 109/12/4 to 109/12 x 4

9. Simplify 12 x 4 to 48

x = 109/48

Hope this helps & happy halloween! :)
