The perimeter of a rectangular swimming pool is 414 meters. The length of the pool is 7 meters more than four times the width. F

PolarNik [594]

Answer:

Width = 40 meters

Length = 167 meters

Step-by-step explanation:

Let

Width of the pool = x meters

Then

Length of the pool = 4x + 7 meters

and

Perimeter $=2(x+4x+7)=2(5x+7)=10x+14$ meters

Hence,

$10x+14=414\\ \\10x=414-14\\ \\10x=400\\ \\x=40\ meters\\ \\4x+7=4\cdot 40+7=167\ meters$

Find the value of x to the nearest tenth. *

Alla [95]

Answer:

x ≈ 61.8

Step-by-step explanation:

Using the sine ratio in the right triangle

sin15° = $\frac{opposite}{hypotenuse}$ = $\frac{16}{x}$ ( multiply both sides by x )

x × sin15° = 16 ( divide both sides by sin15° )

x = $\frac{16}{sin15}$ ≈ 61.8 ( to the nearest tenth )

Solve for the value of x: x/2 + x/3 = 2x/5 + 3 , also I need a very thorough explanation for this.

Alona [7]

Answer:

$x=\frac{90}{13} .$

Step-by-step explanation:

$\frac{x}{2} +\frac{x}{3} =\frac{2x}{5} +3;$

$30*(\frac{x}{2} +\frac{x}{3} )=30*(\frac{2x}{5} +3);$

15x+10x=12x+90; ⇔ 13x=90;

$x=\frac{90}{13}.$
