Answer:
The closet equivalent of the ratio of 'a' to 'c' is:

Step-by-step explanation:
Given
i.e.
a=0.63x
i.e.
c=3/8x
Hence,


Thus, the closet equivalent of the ratio of 'a' to 'c' is:

Answer:
c = 80 ÷ 5
Or
5c = 80
Step-by-step explanation:
It's pretty self explanatory. All you have to do is convert the words into an equation.
Answer:
The correct answer is - 17.
Step-by-step explanation:
Given:
total students = 219
in chemistry = 112
in physics = 45
not enrolled in either of these = 79
solution:
The number of students in both classes can be calculated by
P ( A or B) = P (A) + P (B) - P (A and B)
then putting and solving the given vaues in formula
=> (219-79) = 112+45-x
=> 140 = 157 -x
=> 17 = x
Answer:
A = 58.7 degrees
B = 66.9 degrees
C = 34.1 degrees
Step-by-step explanation:
<u><em>For <A:</em></u>
Tan A = 
Tan A = 
Tan A = 1.6
A = 
A = 58.7 degrees
<u>For <B:</u>
Sin B = 
Sin B = 
Sin B = 0.92
B = 
B = 66.9 degrees
<em><u>For <C:</u></em>
Sin C = 
Sin C = 
Sin C = 0.56
C = 
C = 34.1 degrees
(1.06)60 is greater than 60, because 1.06 multiplied by 60 is 63.6, and 63.6 is greater than 60. Hope this helps fam
