Answer:
5 cm
Explanation:
First, let's find the perimeter of the rectangle.
The perimeter of a rectangle is:
p=2l+2w
In this rectangle, we know that the length is 7 centimetres and the width is 3 centimetres.Therefore, we can substitute 7 in for l and 3 for w.
p=2(7)+2(3)
Multiply 2 and 7
p=14+2(3)
Multiply 2 and 3
p=14+6
Add 14 and 6
p=20
We know the perimeter of the rectangle is 20 centimeters. We also know that the perimeter of the square is equal to the perimeter of the rectangle.
The perimeter of a square is:
p=s+s+s+s or p=4s
We know that the perimeter of the square is equal to the rectangle. The rectangle's perimeter is 20. Therefore, we can substitute 20 in for p.
20=4s
Now, we want to find what the side length is. We have to get s by itself. 4 and s are being multiplied. To reverse this, divide both sides by 4.
20/4=4s/4
20/4=s
5=s
The side length of the square is 5 centimeters.
Answer:
$13,308
Explanation:
5.8% of 6000 is 348. 348 times 21 is $7,308. add 6,000 to 7,308 and you get $13,308
Answer:
Spreading axis
Explanation:
Oceanic crust is constantly being pushed horizontally away from the ridge crest toward an oceanic trench. This ridge crest is known as spreading axis or spreading center. The phenomenon itself is known as seafloor spreading. Seafloor spreading as a theory was first proposed by Harry Hess in 1962. He proposed that sea floor moves, as well as continents. The seafloor moves at a rate of about 1-24 cm per year.
