Answer:
The normal heart rate of the bear is 50 bpm
Step-by-step explanation:
20% of the normal rate (let's assign the letter 'x' to this) is 10 bpm.
So we can write the equation:
![0.2\,*\,x =10\\x=\frac{10}{0.2} \\x=50](https://tex.z-dn.net/?f=0.2%5C%2C%2A%5C%2Cx%20%3D10%5C%5Cx%3D%5Cfrac%7B10%7D%7B0.2%7D%20%5C%5Cx%3D50)
Answer:
2) 1.77 in squared
3) 508.68 in squared
4) 50.24 ft squared
5) 562.6
6) 170.3
Step-by-step explanation:
2) A=r^2pi
d= 2r
3in= 2r
r= 3/2
(3/2)^2pi
7.06858/4
1.77 in^2
3) (18)^2pi
324(pi)
1017.876/2
508
4) (8)^2pi
64pi
201.062/4
50
5) A= 1/2(b1+b2)h
25 -4.2= 20.8
1/2(18+26)20.8
1/2(44)(20.8)
22(20.8)
457.6cm^2
A=lw
25(4.2)
105cm^2
105+457.6= 562.6
6) 2 triangles(1/2(6.2(5)))
31 m^2
18.3(11)
201.3m^2
201.3 -31= 170.3m^2
(-2)(3)^(10-1)
The 10th term is -39366
