A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 miles. What

e-lub [12.9K]

Answer:

Actual area = 21600 Sq.miles

Step-by-step explanation:

We are given;

length; L = 4 inches

Width; W = 6 inches

The scale of the map; 1 inch for every 30 miles i.e. 1 : 30

Since the scale is 1:30, let's find the find the actual dimensions and then the actual area

For the Length,

Since 1 inch represents 30 miles,

Then, 4 inches = (4 × 30)/1 = 120 miles

For the width;

Since 1 inch represents 30 miles,

Then,6 inches = (6 × 30)/1 = 180 miles

Therefore, the actual dimensions are 120 miles and 180 miles

Now, formula for area of rectangle = length × width

Thus;

Actual area = 120 × 180

Actual area = 21600 Sq.miles

A rectangle is placed around a semicircle as shown below. The width of the rectangle is 6 yd. Find the area of the shaded

morpeh [17]

Answer:

15.48 yd squared

Step-by-step explanation:

This is because 6 yards can be used as the radius of your circle. square your radius, so 6x6 which is 36 then multiply by 3.14. You then get 113.04. Since it is a semicircle, divide it by 2. You now get 56.52. If you know your radius, you know your diameter which is 12. 12 is also the length of the rectangle so 6x12 is 72 which is the area of the rectangle. Now subtract 56.52 from 72 to get 15.48 which is the shaded region of the rectangle. So I believe that you are doing yards, so 15.48 yd squared. I hope this helps :)

What is the factorization??

aivan3 [116]

We first find the zeros of the function , the zeros of the function are those at which points the graph of the function crosses or touches the x axis

here we can see in the graph that graph crosses the x axis at two points , 1 and 7

So the zeros of the function are

x=1 and x=7

It means the factor are

(x-1) and (x-7)

So the factorization is given by

(x-1)(x-7)

Solve the system of equations by using substitution.

Flauer [41]

Answer:

x = -3 , y = 2 thus D) is your answer

Step-by-step explanation by substitution:

Solve the following system:

{-9 = x - 3 y

6 - 2 x = 6 y

Hint: | Choose an equation and a variable to solve for.

In the first equation, look to solve for x:

{-9 = x - 3 y

6 - 2 x = 6 y

Hint: | Reverse the equality in -9 = x - 3 y in order to isolate x to the left hand side.

-9 = x - 3 y is equivalent to x - 3 y = -9:

{x - 3 y = -9

6 - 2 x = 6 y

Hint: | Solve for x.

Add 3 y to both sides:

{x = 3 y - 9

6 - 2 x = 6 y

Hint: | Perform a substitution.

Substitute x = 3 y - 9 into the second equation:

{x = 3 y - 9

6 - 2 (3 y - 9) = 6 y

Hint: | Expand the left hand side of the equation 6 - 2 (3 y - 9) = 6 y.

6 - 2 (3 y - 9) = (18 - 6 y) + 6 = 24 - 6 y:

{x = 3 y - 9

24 - 6 y = 6 y

Hint: | Choose an equation and a variable to solve for.

In the second equation, look to solve for y:

{x = 3 y - 9

24 - 6 y = 6 y

Hint: | Isolate y to the left hand side.

Subtract 6 y + 24 from both sides:

{x = 3 y - 9

-12 y = -24

Hint: | Solve for y.

Divide both sides by -12:

{x = 3 y - 9

y = 2

Hint: | Perform a back substitution.

Substitute y = 2 into the first equation:

Answer: {x = -3 , y = 2
