If Shawn drives 45 miles an hour how far can he go in 40 minutes

30miles in 40minutes

Step-by-step explanation:

1h=60minutes

45miles60minutes

X40minutes

X=45×40/60=45×4/6=45×2/3=15×2=30miles

30 miles in 40 minutes

Step-by-step explanation:

First, find the unit rate by dividing miles over minutes. 45/60 = 0.75. So, Shawn drives 0.75 miles in one minute. Next, multiply 0.75 by 40 to get how far he goes in 40 minutes, which equals 30. So, Shawn travels 30 miles in 40 minutes.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
