An = a1 + (n - 1)(d)
Where a1 is the first term and d is the common difference.
First find d, the common difference.
24, ____, 32
a3 a4 a5
Subtract 32-24 = 8
Subtract a5 - a3 = 2
Divide 8/2 = 4
d = 4
Use d and one of the values they give us to find a1.
a3 = 24
24 = a1 + (3 - 1)(4)
24 = a1 + 2(4)
24 = a1 + 8
Subtract 8 from both sides
16 = a1
an = 16 + (n - 1)(4)
Can also be written
an = 16 + 4n - 4
an = 4n + 12
Answer:
70%
Step-by-step explanation:
49/70 = 0.7
0.7*100 = 70%
Answer:
3/2
Step-by-step explanation:
Assuming you meant fractions, to divide them, you must multiply the reciprocal of that fraction. You'll then have:
4/5x15/8
Reduce the numbers of the greatest common factor which is 5:
4x3/8
Reduce the numbers of the greatest common factor which is now 4:
3/2 is your answer
Answer:
b = -18
Step-by-step explanation:
-1/6b=3
Multiply each side by -6
-6*-1/6b=3(-6)
b = -18
Answer with Step-by-step explanation:
Let the volume be represented by 'V'
Since it is given that Volume varies with height 'h' and square of the girth 'g' we can write
where 'k' is a constant of proportionality
Now it is given that volume is 288 cubic meters for h= 40 meters and g =1.5 meters we can write
Thus the volume of the timber as a relation is
Part b)
Volume of 50 trees with height 75 meters and girth 2 meters is
