9514 1404 393

Answer:

  about 100 years

Step-by-step explanation:

2020 -1920 = 100

Outdoor lights were made safe about 100 years ago. (using information given in the problem statement)

_____

<em>Additional comment</em>

2020 -1930 = 90. So, the actual length of time is <em>between 90 and 100 years</em>.

Using additional research, we find mercury vapor lights were made to have a practical color in about 1929, so 91 years ago. They were invented somewhat before the 1920's but had a greenish color. Fluorescent phosphor coating was added in 1929 to make them produce a whiter light.

Solve for m: am/c = n
chubhunter [2.5K]

Hey there! I'm happy to help!

We want to get m all by itself on one side of the equation. To do this, we use inverse operations on both sides of the equation to cancel out variables on one side to isolate m.

am/c=n

We multiply both sides by c.

am=nc

We divide both sides by a.

m=(nc)/a

I hope that this helps! Have a wonderful day! :D

I don’t like to beg but I guess I’m in need..
djverab [1.8K]

Answer:

-4 < n ≤ 5

Step-by-step explanation:

Since the left inequality is an open circle and going to the right, the sign will be >

Since the right inequality sign is a closed circle and is going left, the sign would be ≤

The open circle ends at -4 so, n > -4

The closed circle ends at 5 so, n ≤ 5

You combine them and it looks like this:

-4 < n ≤ 5

Can anyone help Me Please
kari74 [83]

Range of values of x is 32.

<u>Step-by-step explanation:</u>

With Rule of concurrency of two triangles,  we have,

\frac{Angle1}{Side1}  = \frac{Corresponding Angle}{Corresponding Side}

⇒\frac{x+2}{13} = \frac{37}{14}

⇒ 14(x+2) = 37(13)

⇒ 14x + 28 = 481

⇒14x = 453

⇒ x = \frac{453}{14}

On simplifications,  x = 32.37

∴Range of values of x is 32.
