Sisters Helen and Anne live 332 miles apart. For Thanksgiving, they met at their other sister's house partway between their home
Blababa [14]

Answer:

Helen: 60mph and Anne: 50mph

Step-by-step explanation:

3.2r+2.8(r-10)=332 is the equation that we use, given the information we have.

We distribute and combine like terms and add 28 to both sides and divide by 6.

3.2r+2.8(r-10)=332

3.2r+2.8r-28=332

                6r=360

             6r/6=360/6

                  r=60  So, Helen's speed is 60mph.

Next, we'll solve Anne's speed.

r-10=50

60-10=50  So, Anne's speed is 50mph.

A pair of parallel lines is cut by a transversal, as shown (see figure):
Anestetic [448]
The answer
let p' be the corresponding angle of the angle p (that is because of the prallelism and the transversal, look the image)
but p' and p are correspondant angles implies p'=p,
looking at the figure, p' and q are opposite angles
so q=p' and p'=p implies   q=p
the answer is
<span>p = q</span>

A motorboat travels 441 kilometers in 9 hours going upstream and 388 kilometers in 4 hours going downstream. What is the rate of
lianna [129]

Answer:

The rate of the boat in still water is 73 km per hour, and the speed of the current is 24 km per hour.

Step-by-step explanation:

Given that a motorboat travels 441 kilometers in 9 hours going upstream and 388 kilometers in 4 hours going downstream, to determine what is the rate of the boat in still water and what is the rate of the current, the following calculation must be performed:

Upstream = 441/9 = 49 km per hour

Downstream = 388/4 = 97 km per hour

(97 + 49) / 2 = X

146/2 = X

73 = X

97-73 = 24

49-74 = -24

Therefore, the rate of the boat in still water is 73 km per hour, and the speed of the current is 24 km per hour.
