Answer:
One less than 25, 24, times five is 120, and that is 4 times as much as 30 so you already know it is wrong.
Step-by-step explanation:
Answer:
b = 6
Step-by-step explanation:
In (y^b)^4=1/y^24 we can re-write (y^b)^4 as y^(4b) and then equate this result to y^24. Setting the exponents equal to one another, we get 4b = 24, or b = 6.
Answer:

balance = 200 - 5 m where m = number of months
Answer:
Step-by-step explanation:
Mathematically, the area of a sector can be calculated using the formula below;
area of sector = angle/360 * pi * r^2
From the question, angle = 180
pi= 22/7
r = d/2 = 5.6cm/2 = 2.8 cm
So the area of the sector is as follows;
A = 180/360 * 22/7 * 2.8^2
A = 2 * 22/7 * 2.8^2 = 49.28
which is 49.3 cm^2 to the nearest tenth
