The answer is 2. Imagine Maria can paddle 4 miles in either direction if there was no current in 2 hours. But if we add the current then we would subtract 2 when she goes upstream so she would get 4-2 which is 2 miles. And would get an extra 2 miles going downstream. So 4+2= 6 miles.

So the speed of the current is 2 mph.

Hope this helps!

Answer:

The correct answer is: Δ ARS ≅ Δ AQT

Step-by-step explanation:

Given:

1) AR = AQ

2) ∠1 ≅ ∠3

If AR = AQ then ΔARQ is equilateral triangle, angles on the base of the equilateral triangle are the same.

3) ∠R ≅∠Q

According to this we have statement Angle-Side-Angle

Δ ARS ≅ Δ AQT

Answer:

A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.

A leaf is falling from the top of a tree. The height of the leaf in feet, y, can be found using the function y = -3.5x + 28, whe
Bess [88]

Answer:

It took 8 seconds for the leaf to reach the ground.

Step-by-step explanation:

The height of the leaf in feet can be found using the function:

y = -3.5*x + 28

where x is the time in seconds the leaf has been in the air.

You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:

0= -3.5*x + 28

and solving you get:

-28= -3.5*x

(-28)÷ (-3.5)=x

8=x

<u><em> It took 8 seconds for the leaf to reach the ground.</em></u>
