Rotation counterclockwise 90 degrees has the rule

(x,y) -> (-y,x)

So the image is obtained, according to the rule, 
(2,3) -> (-3,2)

A motor club has estimated that a 325 mile car trip will take 6 1/2 hours. What is the club assuming to be the average speed mil
In-s [12.5K]

<u>Answer: </u>

The average speed that the club is assuming is 50 miles per hour

<u>Solution: </u>

We know that Distance = Speed × Time.

Here it is given that distance is 325 miles and the time to cover 325 miles is 6_{2}^{1} hours which is equal to \frac{13}{2} hours.

Now to find the average speed mile per hour we use the formula

\begin{aligned} \text { Speed } &=\frac{\text { Distance }}{\text { time }} \\ &=\frac{325}{\frac{13}{2}} \\ &=\frac{325 \times 2}{13} \end{aligned}

By cancelling 325 by 13 we get 25

= 25 × 2  

= 50 miles per hour

Thus the average speed that the club is assuming is 50 miles per hour.

Does anyone know how to solve this?
kondaur [170]

Answer:

Step-by-step explanation:

<2 + <1 + 20 = 180                 A straight line has 180 degrees.

<2 is given as 90 degrees.

90 + <1 + 20 = 180                Combine like terms

<1 + 110 = 180                        Subtract 110 from both sides

<1 = 180 - 110

<1 = 70

<1 + <2 + <3 = 180

<1 = 70

<2 = 90

70 + 90 + <3  = 180

160 + <3 = 180                    Subtract 160 from both sides

<3 = 180 -  160

<3 = 20

20 + 20 + <4 = 180            Straight line theorem stated above.

40 + <4 = 180                     Subtract 40 from both sides

<4 = 180 - 40

<4 = 140

It takes Ty 4 hours 30 minutes to read his favorite book, reading at a constant rate of 100 pages
AysviL [449]

Answer:

540 pages

Step-by-step explanation:

100 pages = 50 mins

??? pages = 270 mins (converted 4hrs 30 mins to minutes)

Now you could cross multiply to find what the number of pages are:

100 pages x 270  mins = 50 mins x ??? pages

27000 = 50 mins x ??? pages

27000/50 = ??? pages

540 = ??? pages

So there are 540 pages in his favourite book.
