Line up the decimal point to each number in order from left to right and subtract to get the difference which should be -0.248
Answer:
21, 17, 13
Step-by-step explanation:
Find the mean of the 2 given values
mean = 
= 
= 17
Noe find the mean of 25 and 17 and 17 and 9
mean = 
= 
= 21 and
mean = 
= 
= 13
Thus the 3 means are 21, 17 and 13, that is
25, 21, 17, 13, 9
Answer:
Area of the field that the cow graze = 235.71 sq. ft
Step-by-step explanation:
Area of the field that the cow graze = (120 / 360) * πr²
= (1/3) * (22/7) * 15 * 15
= (22 * 5 * 15) / 7 = 1650 /7
= 235.71 sq. ft
1. Take the two x-axis intersections.
For Q 31 it is:
x = -4 and x = 0
2. Reorganise the previous equations
x +4 = 0 and x = 0
3. Put the x side in brackets
x(x+4)
4. Done
—-
Q 32
x = -1
x = 5
x + 1 = 0
x - 5 = 0
(x+1)(x-5)
