11Alexandr11 [23.1K]

Answer:

Kirsten travels 7.5 miles to go to work.

Step-by-step explanation:

Bike: 10 MPH

Time: 1/4 Hour

1/4 of 10 = 2.5

Distance travelled on bike: 2.5 miles

Train: 20 MPH

Time: 1/4 Hour

1/4 of 20 = 5

Distance travelled by train: 5 miles

Add the distances together.

5 + 2.5 = 7.5

7.5 miles

1. -10=xy+z, solve for x please? 2. h-4/j =k, solve for j please?

ANEK [815]

Answer:

$x=\frac{-10-z}{y}$

Step-by-step explanation:

1 Subtract z from both sides.

$-10-z=xy$

2 Divide both sides by y

$\frac{-10-z}{y} =x$

3 Switch sides.

$x=\frac{-10-z}{y}$

2nd question

Answer: $j=-\frac{4}{k-h}$

Step-by-step explanation:

1 Subtract h from both sides

$-\frac{4}{j} =k-h$

2 Multiply both sides by j.

$-4=(k-h)j$

3 Divide both sides by k−h.

$-\frac{4}{k-h}=j$

4 Switch sides.

$j=-\frac{4}{k-h}$

A man is parasailing on a lake. The rope he is holding is 150 feet long and he is 45 feet above the water. What is the horizonta

ss7ja [257]

9514 1404 393

Answer:

143.1 ft

Step-by-step explanation:

Assuming the rope is tied to the boat, and that the geometry can be modeled by a right triangle, the Pythagorean theorem is helpful.

150² = 45² + d²

d = √(150² -45²) = √20475 ≈ 143.1 . . . . feet

The horizontal distance between the man and the boat is about 143.1 feet.
