A water pipe is 4 7/12 feet beneath the surface of the road. What is the elevation of the pipe, in feet, expressed as a decimal?

Furkat [3]

Answer:

4.5833feet

Step-by-step explanation:

Given the elevation of a water pipe as 4 7/12 feet

Expressing as decimal

4 7/12

= 4 + 7/12

= 4 + 0.5833

= 4.5833

Hence the elevation of the pipe expressed as a decimal is 4.5833feet

What is the solution set of (3x - 1)^2 = 5?<br><br><br> HEEEELLLLLLLLLLLPPPPPPPPP

babunello [35]

*I'll be keeping the solutions in exact form*

So firstly, square root both sides. This will split the equation into two:

$3x-1=\sqrt{5} \\ 3x-1=-\sqrt{5}$

Next, add 1 on each side: $3x=\sqrt{5}+1 \\ 3x=-\sqrt{5}+1$

Next, divide 3 on both sides, and your answers will be $x=\frac{\sqrt{5}+1}{3},\frac{-\sqrt{5}+1}{3}$

Answer:

Step-by-step explanation:

Angle FEG and angle DEF are supplementary (They both form a 180 degree angle) so you can conclude:

180 = 119 + angleFEG

angleFEG = 61 degrees

Angle HEG and DEF are vertical angles so you can conclude:

angleHEG = angleDEF

andgleHEG = 119
