Answer:2
Step-by-step explanation:
Number by x
Answers:
25c= 1/2
Then R3.50 is 3/50
Step-by-step explanations:
25c as a fraction is 25/50, so you have to simplify 25/50 to its simplest form , and you get the result of 1/2
For this you have to first find the GCD (or HCF) of numerator and denominator. GCD of 3 and 50 is 1.
3 ÷ 150 ÷ 1.
Reduced fraction: 350. Therefore, 3/50 simplified to lowest terms is 3/50.
Answer:
The value of y when x = 90
y = 22.5
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
The value of y is directly proportional to the value of x.
Y∝ X
y = k x
If y = 45 when x = 180
45 = k ( 180)

<u><em>Step(ii):</em></u>-
The value of y when x = 90
y = 0.25 × 90 = 22.5
y = 22.5
Review the meaning of "straight angles."
Here 110 and A are "straight angles," and so 110 + A = 180 (degrees).
Then A = 70 degrees.
Using variable concepts, it is found that the explanatory variable is the age.
<h3>Explanatory and response variables:</h3>
- The variables of an experiment are divided into explanatory and response.
- The response variable is the one that is the focus of the study, that is, the one that can be changed.
- The explanatory is the one that explains the reason of the change in the response variable.
In this problem, the <u>age can effect the political party preference</u>, hence:
- The variable that is changed is the political party preference, hence it is the response variable.
- The reason is the age, hence it is the explanatory variable.
