The answer
the question is not clear
if it is to determine how to write this phrase as a mathematics equation, it is as follow:
let be x the unknown number
so <span>ighty-seven decreased by three times a number is greater than one hundred sixty-five means  87 - 3x>165, 
so we can solve it easily as 87 - 165> 3x, and then 3 x > 32, and finally the value of x is x > 32/3=10.66</span>

Help asap Which explains how to find the quotient of the division below? -3 1/3 divided by 4/9
noname [10]

Answer:

-7\frac{1}{2}

Step-by-step explanation:

To find the quotient, convert the mixed number to an improper fraction first

-3\frac{1}{3}=-\frac{3*3+1}{3}=-\frac{10}{3}

Find the quotient now

\frac{(-10/3)}{(4/9)}=-\frac{10*9}{4*3}\\ \\=-\frac{90}{12}

Simplify

Divide by 6 both numerator and denominator

=-\frac{15}{2}=-7.5

Convert to a mixed number

-7.5=-(7+0.5)=-(7+\frac{1}{2})=-7 \frac{1}{2}

two men A and B stand on opposite sides of a 100 metre tower.A observes the angle of elevation of the top of the tower as 45 and
Zepler [3.9K]

9514 1404 393

Answer:

  273 m

Step-by-step explanation:

The tower represents the short side of a 30°-60°-90° right triangle. The distance from the tower represents the long leg, not the hypotenuse, of that triangle. It is √3 times the short side. In this geometry, man B is 100√3 = 173.2 meters from the tower.

The tower represents one of two congruent sides of a 45°-45°-90° right triangle. Man A will be standing 100 meters from the tower.

The distance between A and B is 100 +173.2 = 273.2 meters. The men are about 273 meters apart.
