in a marathon race (42.195 km), the winner’s time is 2 hours, 13 minutes, and 9 seconds, while the second-place time is 2 hours,

algol [13]

in a marathon race (42.195 km), the winner’s time is 2 hours, 13 minutes, and 9 seconds, while the second-place time is 2 hours, 26 minutes, and 6 seconds . The distance is 2.664 km.

D = distance of marathon = 42.195 km = 42195 m

tw = time taken by winner = 2 h 17 min = 2 (60) + 17 = 137 min = 137 (60) = 8220 sec

Vw = speed of winner

speed of winner is given as

Vw = D /tw = 42195/8220

ts = time taken by second place = 2 h 26 min 14 sec = 2 (60)(60) + (26)(60) + 14 = 8774 s

Vs = speed of second place

speed of second place is given as

Vs = D /ts = 42195/8774

distance of the second place holder from the finish line is given as

D' = Vs (ts - tw)

D' = (42195/8774 )(8774 - 8220)

D' = 2664.24 m

D'= 2.664 km

Work out the area of Triangle ABC

Tema [17]

The main idea is using the Pythagorean formula to find the length of line segment $DB$ .

Alr so you use the formula $A^2 + B^2 = C^2$

$C^2$ is already given and is $2\sqrt{5}$

and $A^2$ is $3\sqrt{2}$

So using algebraic rules you'll get $B$ as:

$\sqrt{2}$

Now using the formula: $\frac{1}{2} b * h$ , you can find the area of tri ABD and CBD which would be $3$ and $1$ so add them up and you get $4$ !

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

We know that 12 out of 30 employees said they work overtime on a regular basis. If we assume that this sample represents well all the employees, we can extend this proportion to all employees:

$12\div 30 = x \div 200 \iff x = \dfrac{12\cdot 200}{30} = 80$

So, if 12 out of 30 randomly selected employees said they work overtime on a regular basis, we assume that 80 out of all the 200 employees work overtime on a regular basis.

Note that this is a strong assumption: in the worst case, there are 12 employees working overtime, and we have been unlucky to pick them all in our sample.

Anyway, if our assumption is correct, knowing that 80 out of 200 employees work overtime on a regular basis leads to a percentage of

$\dfrac{80}{200}=\dfrac{40}{100}=40\%$
