Answer:
c= 20h + 60
Step-by-step explanation:
The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.

Answer:
£8 : £12
Step-by-step explanation:
2:3 means that there are 5 parts in total. Let parts be represented as p. 5p = £20, p = £4. That meant 2 parts = £8 and 3 parts = £12. Hence to share £20 in the ratio 2:3 is £8 : £12
To solve the problem shown in the figure attached, you must apply the proccedure shown below:
1. You have that the equation for calculate the area of a circle is:
A=πr²
2. You have that the formula for calculate the diameter of a circle is:
d=2r
Therefore, the radius is r=d/2
where r is the radius of the circle
3. Keeping the information above on mind, you have the correct sequence of the equations by clearing the diameter d, is shown below:
A=π(d/2)²
A=πd²/4
4A=πd²
d²=4A/π
d√(4A/π)
Therefore, as you can see, the answer is:
A=π(d/2)²
A=πd²/4
4A=πd²
d²=4A/π
d√(4A/π)
