53×0.2 = 10.6
53×0.06= 3.18
53+3.18+10.6= 66.78
So the answer is $66.78 / number 2
Pythagorean Theorem: a^2 + b^2 = c^2
-A and B are legs of the triangle
-C is the hypotenuse
#1.
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
c = 10
#2.
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
c = 13
#4.
10^2 + 4^2 = c^2
100 + 16 = c^2
116 = c^2
c =
#5.
15^2 + 9^2 = c^2
225 + 81 = c^2
306 = c^2
c =
#6.
120^2 + b^2 = 150^2
14400 + b^2 = 22500
b^2 = 8100
b = 90
#7.
144^2 + b^2 = 194^2
20736 + b^2 = 37636
b^2 = 16900
b = 130
Hope this helps!! :)
Answer:
3.77 rounded is 3.8
Step-by-step explanation:
0=-4.9t^2+70
+4.9t^2
4.9t^2=70
divided by 4.9 on (both 4.9 and 70)
t^2=squareroot 14.285= 3.77
