Answer:
Step-by-step explanation:
Oldest friend=X+2; Middle friend=X+1; Youngest friend=X
X+(X+1)+(X+2)=180
3X+3=180 Subtract 3 from each side.
3X=177 Divide each side by 3
X=59 Youngest friend is 59.
X+2=59+2=61 ANSWER: Oldest friend is 61.
X+2=59+1=60 Middle friend is 60.
CHECK:
Sum is 180
59+60+61=180
180=180
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

Answer:
its B. A = 0t3 B = (–0.6t2) C = 18t D = (–8)
the next answer is D. 1.3^3 - 0.2t^2 - 6t - 8
$-8 was the total change in value of the stock over the four-day period
