Answer:

12(x+3) square inches.

Step-by-step explanation:

Given:

A square green rug has a blue square in the center.

The side length of the blue square is x inches as shown in the figure:

The width of the green band that surrounds the blue square is 6 inches.

Question asked:

What is the area of the green band ?

Solution:

<u>Side length of blue square = </u>x<u />

First of all we will calculate area of blue square.

As we know:

Area of square=(Side)^{2}

                       =x^{2}

Thus, area of blue square = x^{2}

Now, we will calculate area of square green rug:

Side length of green rug = Side length of blue square + width which surrounds the blue square

Side length of green rug = x+6

Thus,  area of square green rug = =(x+6)^{2} \\

<em><u>Now, we will find area of the green band ( shaded region with green color as shown in the figure)</u></em>

Area of the green band = Area of square green rug -  Area of blue square        

                                       =(x+6)^{2} -x^{2} \\=(x+6+x)(x+6-x)\               [a^{2} -b^{2} =(a+b)(a-b)]

                                       =(2x+6)6\\=12x+36\\

                                       =12(x+3)\ taking\ 12\  as\ common

Therefore, the area of the green band is 12(x+3) square inches.

A convertible is traveling at 45 miles per hour, and its wheels have a diameter of 48 inches. How many complete revolutions do t
neonofarm [45]
To answer this question you will need to know how many inches the car travels Per minute.

1. To find this out you will first divide 45 miles by 60 to get the number of miles per minute.

The convertible travels 0.75 mi./min.

2. Next you will convert this number of miles to inches.

There are 63,360 inches per mile.

0.75 x 63360 = 47520 inches per minute.

3. You then need to find the distance the wheel travels in one rotation. You will need to find the circumference of the wheel.

C = pi x d
3.14 x 48
C = 150.72 inches
Each rotation is about 150.72 inches.

4. Finally, divide the total distance traveled in a minute by the circumference(distance of one rotation) to get the total number of rotations in a minute.

47520/150.72 is about 315.3 rotations per minute.

devlian [24]
Since 1/2 is equal to a half, you divide 50 and 40 by 2 and you'll get 25 and 20 and then you subtract 25 and 20 and you get 5 which is the answer!

I need help with number 19
inysia [295]
Let's start by understanding that the graph is a linear line. We have a common difference if 4.5 for every 10x we have more.

We can start by finding the gradient, using rise over run. Let's take (10, 4.5) and (20, 9)

Our rise is 9 - 4.5 = 4.5 and our run is 10. Then, our gradient becomes 4.5/10 = 0.45

Now, we can substitute points using the point-slope form.

y - 4.5 = 0.45(x - 10)
y - 4.5 = 0.45x - 4.5
Hence, our line becomes y = 0.45x and you can verify by substituting in points from the table.
