Diano4ka-milaya [45]

Answer:

t_a = 7 s

t_w = 5 s

Step-by-step explanation:

Given:

- The average speed in air v_a = 16 m/s

- The average speed in water v_w = 3 m/s

- The total distance D = 127 m

- The total time T = 12 s

Find:

How long did the stone fall in air and how long did it fall in the water?

Solution:

- Lets time taken by stone to drop through air as t_a = t_a.

- The time taken in water would be t_w = (12 - t_a)

- The total distance covered can be calculated as:

                            D = v_a*t_a+ v_w*(12 - t_a)

                            127 = 16*t_a + 3*(12 - t_a)

Simplify and solve for t:

                            91 = 16*t_a - 3t_a

                            13*t_a = 91

                            t_a = 7 s

                            t_w = 5 s

The equation y = 1.55x + 110,419 approximates the total cost, in dollars, of raising a child in the United States from birth to
Mariana [72]

Answer:

The answer to your question is The cost to raise a child from birth to 17 years in a household is $194119.

Step-by-step explanation:

Equation

                      y = 1.55x + 110,419

Annual income = $54,000

To solve this problem just substitute the annual income and simplify to find the cost.

                    y = 1.55(54,000) + 110419

Simplify

                    y = 83700 + 110419

Result

                    y = $194119

A rectangle has a width of 10 feet and a length of 40 feet. What is the length of the side of a square with the same area?
never [62]
First find the area of the rectangle: 10 * 40 = 400

Now, since the square has the same area, we'll find the side lengths of the square by just finding the square root of 400 which is 20. You can do this with a calculator. So the side length of any side on the square is 20.
