Answer:

About 11.31

Step-by-step explanation:

a^2 + b^2 = c^2

4^2 + b^2 = 12^2

16    + b^2 = 144

-16                  -16

b^2 = 128

Take the square root of both sides

b= approximately 11.31

The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 40 cm, find its area
mel-nik [20]

Answer:

96

Step-by-step explanation:

The length of a rectangle is 4 cm longer than its width. If the perimeter of the rectangle is 40 cm, find its area

width + 4 = length

width = width

2l + 2w = p

width+width +width +width +4 +4 = 40

4width +8  = 40

4width =  32

width = 8

length x width = area

width = 8

length = 12 (width + 4)

12x 8 =  96

Lorenzo drew 3 triangles, 4 rectangles, and 7 arrows in a set of 20 shapes. The only other type of shape in the set is a circle.
djyliett [7]

Answer:

\large\boxed{6/20}

Step-by-step explanation:

In this question, we're trying to find how many circles are there and represent it as a fraction.

We know that he drew:

  • 3 triangles
  • 4 rectangles
  • 7 arrows
  • Set of 20 shapes

We need to find how many circles are there.

3 tiangles + 4 rectangles + 7 arrows = 14 shapes

We know that there is suppose to be 20 shapes, this means that the remaining amount would be circles (6 circles)

We now know that there are 6 circles and 20 shapes in total.

This means that the fraction that would represent circles is 6/20
