An artist makes a scale drawing of a new lion enclosure at the zoo. The scale is 1 in : 25 ft. On the drawing, the length of the enclosure is 7.25 inches. What is the actual length of the lion enclosure in feet?

Answers

Answer:

The actual length of the lion enclosure is 181.25 feet.

Step-by-step explanation:

Given:

An artist makes a scale drawing of a new lion enclosure at the zoo.

The scale is 1 in : 25 ft.

On the drawing, the length of the enclosure is 7.25 inches.

Now, to find the actual length of the lion enclosure in feet.

Let the actual length of the lion enclosure in feet bex.

As given the  scale is 1 in : 25 ft.

So, 1 in is equivalent to 25 ft.

Thus, 7.25 inches is equivalent to x.

Now, to get the actual length of the lion enclosure by using cross multiplication method:

(1)/(25) =(7.25)/(x)

By cross multiplying we get:

x=181.25\ feet.

Therefore, the actual length of the lion enclosure is 181.25 feet.

The measure of angle Jkl can be represented using the expression 3x+5 What is the Degree of JKL

Answers

Answer:

65^\circ

Step-by-step explanation:

It is given that the measure of angle JKL can be represented by (3x+5).

And from the figure we can see that the measure of angle JKL is,

(45^\circ+x^\circ)

Both the measures must be equal, hence equating both the angles we get,

(3x+5)=45+x

Solving for 'x' we get,

3x+5=45+x

3x-x=45-5

2x=40

x=(40)/(2)

x=20

Putting the value of 'x' we can calculate the measure of angle JKL,

45^\circ+x^\circ=45^\circ+20^\circ=65^\circ

Therefore, the measure of angle JKL is, 65^\circ.

9/10 divided by (1/10 plus 2/5)

Answers

\boxed{ ( (9)/(10) )/(( (1)/(10) + (2)/(5) )) = ( (9)/(10) )/( (1)/(2) ) = (9)/(10) . (2)/(1) = (18^(/2))/(10^(/2)) ~\to~\boxed{ (9)/(5)} }
1.8 is the answer

1/10+2/5 is equal to 0.5

That divided by 9/10 is 1.8 or 1 8/10
