Answer:</h2>
<h2>12 miles</h2>
Step-by-step explanation:
Given information :
Mr. Gonzalez drove 30 miles in March. In January, she drove 1/5 as much as in March.
30 ÷ 5 = 6 miles in January
in JanuaryShe drove 2 times as many miles in February as she did in January. In January, she drove 30 miles.
6 x 2 = 12 miles in February
It is already in simplest form, since 17 is a prime number.
This is an easy one.
first you move 2/3 to the other side
x=3-2/3
so you get
x=1/3
Answer:
The sound intensity is about 101.9 dB
Step-by-step explanation:
Sound intensity is the amount of sound energy per unit area.
The intensity of the dog bark is 10⁻⁵ W/in². The intensity of sound in decibels is given by:
I = 10⁻⁵ W/in² = 0.0155 W/m²
Therefore:
The sound intensity is about 101.9 dB
It can be solved by factoring or taking the root of both sides.
x= 2 radical 3. and -2 radical 3
