Ksivusya [100]

Answer:

$125\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

In the right triangle ABC find the length side BC

we know that

$tan(62\°)=\frac{124}{BC}$

$BC=\frac{124}{tan(62\°)}$

step 2

In the right triangle ABD find the length side BD

we know that

$tan(33\°)=\frac{124}{BD}$

$BD=\frac{124}{tan(33\°)}$

step 3

we know that

The distance between the two boats is the length side CD

$CD=BD-BC$

substitute the values

$CD=\frac{124}{tan(33\°)}-\frac{124}{tan(62\°)}=125\ ft$

A man can paint one house in 12 hours. At this rate, how many houses could 18 men paint in 6 hours? A) 3 houses B) 6 houses C) 9

Mademuasel [1]

Answer:

The correct option is C. 9 houses could 18 men paint in 6 hours.

Step by step explanation:

Let the number of houses paint by 18 men in 6 hours be x.

One man can paint one house in 12 hours.

The part of house painted by a man in 1 hour is $\frac{1}{12}$ .

The part of house painted by a man in 6 hour is

$\frac{6}{12}=\frac{1}{2}$

The total number of men is 18. Therefore the number of houses painted by 18 men is

$x=\frac{1}{2}\times 18=9$

Therefore correct option is C. 9 houses could 18 men paint in 6 hours.
