When a river flows, the strength or force of the river depends on how far the river falls vertically compared to how far it flows horizontally find the slope of the river shown to the right. 81ft width 384 is the length

The slope of the river is 0.210 ft.

Step-by-step explanation:

Given : When a river flows, the strength or force of the river depends on how far the river falls vertically compared to how far it flows horizontally, 81 ft width 384 is the length.

To find : The slope of the river?

Solution :

Slope is defined as how many units we move along the y-axis when we move along the x-axis.

We have given length i.e. horizontal distance or x-axis of the river is 384 ft.

and width i.e. vertical distance or y-axis of the river is 81 ft.

By definition of slope,

Therefore, The slope of the river is 0.210 ft.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
