A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Maia says that the lines in this system of linear eqations are parallel. is she correct? explain.
2x+y=14
2y+4x=14

Answers

Answer:

yes, they are parallel because their slopes are the same

Step-by-step explanation:

if you put each equation into slope-intercept form and compare slopes you can see whether they are parallel or not

2x + y = 14

y = -2x + 14

slope = -2

2y + 4x = 14

2y = -4x + 14

slope = -4/2, which simplifies to be -2

Yes they are parallel

determine the solution to the equation.

Which measurement is closest to the circumference of a circle with an area of 36 square feet?
A
12.0 feet
B
21.3 feet
С
103.2 feet
D
113.0 feet

Answers

It’s D! Have a great day

The measurement of the circumference of a circle is 21.3 ft.

What is Circumference of Circle?

The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.

Here, given area of circle = 36 ft²

Area of Circle = πr²

           36 = 3.14 X r²

           r² = 11.46

          r = 3.38 ft.

Circumference of Circle = 2πr

                                       = 2 X 3.14 X 3.38

                                      = 21.25 ft. ≈ 21.3 feet

Thus, the measurement of the circumference of a circle is 21.3 ft.
