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

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

There are about 76.9 million pet dogs and 87 million pet cats in the United States. The number of pet dogs is what percent less

Dmitriy789 [7]

Answer:

The number of pet dogs are 11.61% less than the number of pet cats.

Step-by-step explanation:

Number of pet dogs in the United states = 76.9 million

Number of pet cats in the United states = 87 million

Difference between the number of cats and dogs :

$=87 million- 76.9 million = 10.1 million$

Percentage of number of pet dogs less than pet cats:

$=\frac{\text{Difference}}{\text{Number of cats}}\times 100$

$=\frac{10.1 million}{87 million}\times 100=11.61\%$

The number of pet dogs are 11.61% less than the number of pet cats.
