there are 360 degrees in a complete circle
360/18 = 20
so the answer is C
Answer:
It costs $42.43
Step-by-step explanation:
Lets explain how to solve the problem
- The cost of
kilogram of candy is $7.5
- We need to find the cost of
kilogram
We can use the ratio to find the answer
======= Dollar : Kilogram
======= 7.5 : 
======= c :
By using cross multiplication
∴ c ×
= 7.5 × 
∵
= 
∴
= 
∴ c ×
= 7.5 × 
∴ c ×
= 
Divide both sides by 
∴ c =
÷ 
Change the division sign to multiplication sign and reciprocal the
fraction after the division sign
∴ c =
×
∴ c =
= 42.43 dollars
∵ c represents the cost of
kg
∴ It costs $42.43
Answer:
a. around 36.36 hours; around 28.57 hours
b. $134.21; $159.38
Step-by-step explanation:
Answer:
w=[-14.1667, ∞)
Step-by-step explanation:
the variable w can be any real number less than the value of 85, thus -6 multiplied by any number greater than the value of 14.1667 shall be less than 85. the value for the minimum limit number is obtained dividing 85 by -6 due to the varibale -6w and the value 85 as the maximum limit.
Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx
