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

The shape below contains a rectangle and four semi-circles. What is the perimeter of the shape above? What is the area of the sh
Colt1911 [192]

Answer:

Step-by-step explanation:

lets find out the perimeter P

P rectangle= 2*L+2*W=(2*5)+(2*13)=10+26=36

P small semi-circle ( we have 2), where the d=5, r=2.5

Circumference small circle=2*3.14*r= 2*3.14*2.5=15.70

P 2 small circles=15.70*2=31.40

but we need just half of this, because we have semicircles=15.70

Circumference big semicircle (we have 2), where d=13, r=6.5

C big circle=2*3.14*6.5=40.82

Ps big circle=2*40.82=81.64

we need half of this also, so is 40.82

P total figure=36+15.70+40.82=92.52

Area rectangle=5*13=65

Area small circle, basically the 2 semicircle = 1 circle

Area=3.14*r^2=3.14*2.5^2=19.63

Area big circle=3.14*6.5^2=132.73

Area total figure=65+19.63+132.73=217.36

What is the slope of the line that<br> contains the points (13,-2) and (3.-2)
Allushta [10]

Points are

  • (13,-2)
  • (3,-2)

\boxed{\sf Slope(m)=\dfrac{y_2-y_1}{x_2-x_1}}

\\ \sf\longmapsto m=\dfrac{3-13}{-2+2}

\\ \sf\longmapsto m=\dfrac{-10}{0}

\\ \sf\longmapsto m=0

Nadya [2.5K]

Answer:

-13/2

Step-by-step explanation:

7(y+3)=5y+8

7y+21=5y+8

7y-5y+21=8

2y+21=8

2y=8-21

2y=-13

y=-13/2

Find 2 sum whose sum is 4806 and difference is 1050 explanation​
arlik [135]

Answer:

The two numbers are 2928 and 1878

Step-by-step explanation:

Given this information, we can set up two equations:

x + y = 4806

x - y = 1050

We can solve these simultaneous equations by elimination, which means we can either add or subtract the two equations to solve one of the variables.

In this case, adding the equations together will eliminate y so we can solve for x (remember that y + - y is the same as y - y):

   x + y = 4806

+  x - y = 1050

____________

   2x     = 5856

This can then be simplified to x = 2928 (by dividing by 2)

Now we know x, we can substitute this value into any equation to find y:

2928 + y = 4806 so y = 4806 - 2928 which is 1878.

The two numbers are 2928 and 1878.

Hope this helps!
