Answer:

61.8 feet to nearest tenth.

Step-by-step explanation:

USING THE PYTHAGORAS THEOREM:

55*2 = 21^2 + h^2  where h is the height of the top of the ladder from the ground.

h^2 = 55^2 - 21^2

      =  2584

h = √2584

   =  50.83 ft.

So the height of the building

= 11 + 50.83

= 61.83 feet.

turin the numbers 5x-4 6x-23 -2x+33 into a expression and them simplify the expression. PLZ HELP ME!!!!!!!!!!!!!!!!!!!!!! ITS WO
lapo4ka [179]

Answer:

This expression is missing operators and has no meaning. If you add commas to separate the expressions, and equals signs where appropriate, then assistance can be given.

Assuming that the blank spaces between terms are meant to be plus signs, then the final answer would be 9x.

Step-by-step explanation:

To make some sense of this, let's assume that the operator between "5x-4" and "6x-23" is a plus sign, and that the minus sign on "-2x + 33" is itself the operator there.  If that is the case then this can be solved by simply grouping like terms and summing them up:

5x - 4 + 6x - 23 - 2x + 33

group like terms:

5x + 6x - 2x - 4 - 23 + 33

(5 + 6 - 2)x + (-4 - 29 + 33)

The numbers with no coefficient add up to zero:

9x + (0)

Leaving us with the final answer.

9x

I believe the answer would be 300. One eighth of the class would be 100 and 1/2 of the class would be 400. 800-(400+100)=300. Hope this helped!
