The length of a rectangle is 9 inches more than twice it’s width. If the perimeter of the rectangle is 48 inches find its length and width.

Answers

Answer:

$Length=19 inches\n\nWidth=5 inches$

Step-by-step explanation:

Let the width of the rectangle be 'w' inches

length of the rectangle= (2w+9) inches

Perimeter of the rectangle= 48 inches

Perimeter of a rectangle= 2(Length+Width)

$48=2((2w+9)+w)\n\n48=2(2w+9+w)\n\n48=2(3w+9)\n\n48/2=3w+9\n\n24=3w+9\n\n3w=24-9\n\n3w=15\n\nw=15/3\n\nw=5 inches$

$Width= 5 inches$

$Length=(2w+9)=2(5)+9=19 inches$

$Length=19 inches\n\nWidth=5 inches$

Answer: $30.52

Step-by-step explanation:

Hi, to answer this question we have to calculate the surface area of the ornament:

Surface Area of a sphere = 4π r²

Replacing with the values given:

A = 4(3.14) (9)² = 1,017.36in2

Finally, we have to multiply the surface area by the price per square inch of glass.

1,017.36 (0.03)= $30.52

Feel free to ask for more if needed or if you did not understand something.

Answer:

$30.52

Step-by-step explanation:

4 x 9^2 x 3.14 x 0.03 = around 30.52

Adam’s house is 2 centimeters from Juan’s house on a map. If each centimeter on the map represents 6 kilometers, how far apart are the two houses?

Answers

If one centimeter on the map represents 6 kilometers, then all you need to do to find out how far Adam's house is from Juan's is to multiply the distance between the two houses on the map in centimeters by the amount of kilometers that each centimeter on the map represents.

2 * 6 = 12

Which is our answer.
Adam's house is 12 kilometers from Juan's house.
Hope that helped! =)

12 kilometres.

If one centimetre is equivalent to 6 kilometres then two centimetres is equivalent to 12.

We know that for every 5 red bricks there were 2 gray bricks.

The total amount of red bricks and grey bricks in this sample is 7.

5 red bricks + 2 grey bricks = 7 bricks

Now, we divide 175 "total number of bricks used" by 7 "5 red bricks + 2 grey bricks = 7 bricks" and we will get a quotient of 25.

Now we know that 25 bricks is $(1)/(7)$ of the wall. The gray bricks are $(2)/(7)$ so we can multiply 25 by 2 and we will get a product of 50. If 1/7 = 25 grey bricks so 2/7 would be the grey bricks.

175 - 50 = number of red bricks.

Therefore, there were 125 red bricks.

There were 125 bricks knowing that for every 5 bricks there are 2 gray bricks
