horsena [70]

Answer:74.55 beat per minute

Step-by-step explanation:

Given

Heart beat is 52 beat per minute

i.e. B=\frac{52}{60} beat per sec

If heart rate is increases 1.25 % each sec

suppose B is the heart beat at first second therefore heat beat at 2 nd second

B_2=B+1.25 \% B

B_2=B(1+1.25 \% )

For 3 rd sec

B_3=B(1+1.25\%)+1.25\%B(1+1.25\%)

B_3=B(1+1.25\%)^2

similarly for 3 sec

B_{30}=B(1+1.25\%)^{29}

B_{30}=1.433B

B_{30}=1.242\ \text{beat per second }

B_{30}=74.55\ \text{beat per minute}

Landon babysits and works part time at tge water park over the summer. onw week, he babysat for 3 hours and worked at the water
Tems11 [23]
B = hourly rate for babysitting and w = hourly rate for working at water park

3b + 10w = 109...multiply by -8
8b + 12w = 177...multiply by 3
----------------------
-24b - 80w = - 872 (result of multiplying by -8)
24b + 36w = 531 (result of multiplying by 3)
---------------------add
- 44w = - 341
w = -341/-44
w = 7.75 <=== hourly rate for working at water park

3b + 10w = 109
3b + 10(7.75) = 109
3b + 77.50 = 109
3b = 109 - 77.50
3b = 31.50
b = 31.50/3
b = 10.50 <== hourly rate for babysitting
