Answer:
65,279,520,000 i hope this helps! :)
Step-by-step explanation:
69 * 60 = 4140 number of minutes in an hour
4140 * 24 = 99,360 number of hours in a day
99,360 * 8,760 = 870,393,600 number of hours in a year
870,393,600 * 75 = 65,279,520,000 number of years
an average of 65,279,520,000 heart beats in 75 years
see below
Since RT bisects QRS
1/2 QRS = TRS
1/2 ( 9x+214) = -9x+53
Multiply each side by 2
9x +214 = -18x+ 106
Add 18x from each side
9x +214+18x = 106
27x +214 = 106
Subtract 214 from each side
27x = 106-214
27x =-108
Divide by 27
27x/27 = -108/27
x = -4
TRS = -9x+53
=-9 *-4 +53
= 36+ 53
=89
14/336 ----------> 0.41
you substituto 2 week to 336 cause there are 336 hours in 2 weeks therefore 14/336 = 0.41
the unit rate is 14/336
First we need to find the length. So we do 126/3 to get 42. The length is 42. Now to find perimeter we do 2(42)+2(3) or 42+42+3+3.
Both ways are right ways. The perimeter is 90 meters.
Hope that helps!!
