Answer:
9%
Step-by-step explanation:
10kg=R 20
5kg= R 15
??kg=R22
You add kgs it gives you 15kg and the and money it will give you R35 then
15kg=R35
???=R22
22/35×15 = 9,428571429
=9 %
The height of the triangle would be
7.2 bc
10x7.2:72
So to find the area of a triangle u have to divide by 2, so
72 divided by 2 is 36, so 7.2 is the height
Answer:
41.8887 cm^2
Step-by-step explanation:
area of a circle
A = pi * r^2
A = pi * (3 + 4)^2
A = pi * 49
A = 153.94
120 / 360 = 1/3
153.94 / 3 = 51.3134
now area of inner circle
A = pi * 3^2
A = pi * 9
A = 28.274
28.274 / 3 = 9.4247
subtract
51.3134 - 9.4247 = 41.8887
Set up the equation like 4b+61=0, subtract 61 from both sides, and that'll be 4b=-61. Divide both sides by 4. b=15.25
