Greetings, Agent OOZero. Your mission, if you choose to accept it, is to use the
Olegator [25]

Answer:

Gertrude's favorite is <em>George Burn</em>

What we know from the beginning:

<u>Comedians</u>:

  • George Burn
  • Jack Benny
  • David Letterman
  • Jerry Springfield

<u>Lucy</u>: Jerry Springfield is her favorite

<u>David</u>: Does not like David Letterman

<u>Gertrude</u>: Does not like David Letterman, Does not like Jack Benny anymore

Solving:

  • Since we know that <em>Jerry Springfield is Lucy's favorite</em>, he is not longer an option. This leaves George Burn, Jack Benny, and David Letterman.
  • David and Gertrude do not like <em>David Letterman</em>, so he must be <em>Jose's favorite</em>. This leaves George Burn and Jack Benny
  • Gertrude does not like Jack Benny anymore, so the only one left to be <em>her favorite is George Burn</em>

What is the value of f(−1) when f(x)=2x+2
mart [117]

Answer:

<h2>f( - 1) = 0</h2>

Step-by-step explanation:

f(x)=2x+2

To find f(−1) , substitute the values of x that's - 1 into f(x). That is for every x in f(x) replace it with - 1

That's

f( - 1) = 2( - 1) + 2 \\  =  - 2 + 2

We have the final answer as

f( - 1) = 0

Hope this helps you

Hans is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is feet and its width is feet
Tomtit [17]

Answer:

number of cans Raina will be needed in court floor is 14 cans

Step-by-step explanation:

CHECK THE COMPLETE QUESTION BELOW;

Raina is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is 46 feet and its width is 35 feet. Suppose each can of wood stain covers 115 square feet. How many cans will she need to cover the court?

CALCULATION;

Given:

length of the rectangular shape =46 feet

width of the the rectangular shape = 35 feet.

The floor of the court room is having a rectangular shape, then we need to calculate the surface Area of the rectangular shape first in order to know the number of cans that Raina will be needed

Surface Area= Length × Width

= 46feet × 35 feet

=1610 square ft

Then to get the number of cans , we need to divide the surface Area by each can of wood stain covers which is 115 square feet,

number of cans Raina will be needed in court = 1610 square ft / 115 square ft = 14

number of cans Raina will be needed in court floor is 14cans
