Answer:
3.14 x 14 = 42 + 1.96 = 43.96 (units) sq. or cm^2
Step-by-step explanation:
We remember that; for pi multiplications;
10 x 3 = 30
4 x 3 =12 = 42
That decimals 0.14 x 10's =1.4
That decimal 0.14's x 4 units = 0.56
= (+ 1.4 = 0.56) + 42 = 43.96
Answer:
(b) a = 50 * 2^(t/4)
(c) 951
Step-by-step explanation:
After t hours
a = 50 * 2^(t/4)
After 17 hours
a = 50 * 2^(17/4)
a = 50 * 2^(4.25)
Use calculator
a = 951.3656920022
Rounded
a = 951
Answer:
x = 13
Step-by-step explanation:
First start with the blank equation
![a^{2} + b^{2} = c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2B%20b%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.
![5^{2} + 12^{2} = c^{2}](https://tex.z-dn.net/?f=5%5E%7B2%7D%20%2B%2012%5E%7B2%7D%20%3D%20c%5E%7B2%7D)
Then solve
25 + 144 = ![c^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D)
169 =![c^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D)
![\sqrt{169} = \sqrt{c^{2} }](https://tex.z-dn.net/?f=%5Csqrt%7B169%7D%20%3D%20%5Csqrt%7Bc%5E%7B2%7D%20%7D)
c = 13
We can use proportions
12/x = 10/5
12*5 = 10x
60 = 10x
x = 6
Check
12/6 = 10/5
2 = 2
