Answer:

Step-by-step explanation:

This is the only problem that could be answered with this equation, because you would add the bracelets he made (2+4) then times that number by the days he made them, 5, then divide by the number of groups, 6. Which equals 5 x ( 2 + 4 ) divided by 6.

I hope this helps!

The perimeter of the triangle below is 99 units. Find the length of side WX.

frez [133]

Answer:

Step-by-step explanation:

Perimeter= 99

XV+VW+WX=99

4z+3z+1+z+2=99

8z+3=99

8z= 96

z=96/8

z= 12

WX= z+2= 12+2= 14.

Perpendicular=P=4
Base=B=4

Hypotenuse be H

Apply Pythagorean theorem

$\\ \tt\hookrightarrow H^2=P^2+B^2$

$\\ \tt\hookrightarrow H^2=4^2+4^2$

$\\ \tt\hookrightarrow H^2=32$

$\\ \tt\hookrightarrow H=\sqrt{32}$

$\\ \tt\hookrightarrow H=5.8units$

The loudness, L, of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d, from

kifflom [539]

Answer:

The jetski is 2.28 dB loud when the person is 41 feet away.

Step-by-step explanation:

Loudness (L) ∝ 1 / Distance² (d²)

Introduce a constant 'K'

L = K (1/d²)

L = K/d²

K = Ld²

Find the K from a previously known information: If a person 8 feet from a jetski hears 60 decibels loud

∴ d = 8 ft , L = 60 db

K = 60(8²) = <em>3840</em>

How loud is the jetski when the person is 41 feet away?

Distance is now 41 ft

since: L = K/d²

∴ L = 3840 / 41²

L = 3840 / 1681

L = 2.28 db
