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.

Which of the following is not a correct name for the line shown?
Talja [164]

Answer:

D

Step-by-step explanation:

The line can be named with small latin letters or with two large latin letters which represent two points lying on the line.

Consider all options:

A. Points V and X lie on the line, so you can name the line as VX (true option)

B. Points W and X lie on the line, so you can name the line as WX (true option)

C. p represents the line (small letter given on the diagram) - (true option)

D. You cannot name the line using point V and line p, so this option is false

The diagonals of an isosceles trapezoid are 3x + 7 and 5x – 11. What is the value of x?
Alja [10]
In a trapazoid the diagonals are the same so therefore the two equations equal echother

3x+7=5x-11  solve for x by combining like terms

18=2x  then divide to unto multiplication

9=x

9 is the value of x

I hope I've helped!

Which equation below would be perpendicular to the line y = 2?
nadya68 [22]
Answer:
A) y=1/5x
Step-by-step explanation:
Coz, the way you identify a perpendicular line is by looking for its negative reciprocal. The neagtive reciprocal of 5= 1/5
Now, to check the ans we can multiply the negative reciprocal by "m"
(m in y=mx+c or y=mx+b)
in this case the "m" is stated as 5, so all we need to do is 1/5*5 if the ans is 1 then your ans is right....and over here it is
So thats how you identify & check perpendicular lines!
