A rectangle has a length of 5 square root of 16 and a width of 2 1/5 inches. Find the area of the rectangle
Svetllana [295]

Area of the rectangle is 44 in²

Step-by-step explanation:

  • Step 1: Find the area of the rectangle.

Length of the rectangle = 5√16 in = 5 × 4 = 20 in

Width of the rectangle =  2 1/5 in = 11/5 in            

Area of the rectangle = length × width

                                    = 20 × 11/5 = 44 in²

Answer:

x = 25 degrees

Step-by-step explanation:

All the angles in a triangle must add up to 180 degrees.

That means: 2x + 15 + x + 10 + 3x + 5 = 180

Collect the like terms and put it on one side and put the whole numbers on the other.

2x + x + 3x = 180 - 15 - 10 - 5

6x = 150  

x = 25

Is the point (20,15) on the line? How do you know?
elena-s [515]

Answer:

1. (4, 3) and (8, 6)

2. Yes. The line shows a direct proportion. y = 0.75x

Try (20, 15) in the equation.

15 = 0.75(20)

15 = 15

Point (20, 15) works in the equation, so point (20, 15) is on the line.

3.

Let x = 100.

y = 0.75x

y = 0.75 × 100

y = 75

Since x = 100 gives y = 75, point (100, 75) is on the line.

4.

Let x = 90

y = 0.75x

y = 0.75 × 90

y = 67.5

For x = 90, y must be 67.5. Since this point is (90, 68), it is not on the line.
