If the shelter has 5 times as many cars as dogs if the shelter has a total of the 18 Dogs and cats how many dogs does the shelte
bija089 [108]

Answer:

No. of dogs = 15

Step-by-step explanation:

Let the number of cats be x and the number of dogs be y. The shelter has 5 times as many cats as dogs.

It means, y = 5x ...(1)

Total no of cats and dogs are 18. So,

x+y = 18 ...(1)

Put equation (1) in (2),

x+5x = 18

6x=18

x = 3

No. of cats = 3

Put the value of x in equation (1).

y = 5(3)

y = 15

Hence, there are 15 dogs in the shelter.

A 96 foot tree casts a shadow that is 120 feet long. What is the angle of elevation of the sun? Round to the nearest degree.
zysi [14]

Answer:

\alpha \approx 39^{\circ}

Step-by-step explanation:

Let assume that tree grows perpendicular to surface. The statement is geometrically represented in the attachment included below, which resembles a right-angled triangle. Lastly, the angle of elevation of the sun is determined with the help of the following trigonometric relationship:

\tan \alpha = \frac{96\,ft}{120\,ft}

\tan \alpha = \frac{4}{5}

\alpha = \tan^{-1}\left(\frac{4}{5} \right)

\alpha \approx 38.660^{\circ}

\alpha \approx 39^{\circ}
