Answer:
40 Km
Step-by-step explanation:
Cross-multiply (rule of three)
2.5 cm--------10 Km
10 cm-----------x Km
2.5/10 = 10/x
so
x = 100/2.5 = 40 Km
4x4=16. So think of it like this now..
3x-16=65
Add 16 in each side and you get 3x=81. Divide 3 with 81 and should be 27, or x=27.
Then you check it by putting in the #'s
3(27)-4(4)=65
81-16=65
65=65 ✔️
<span>So you need to find the value of x that would make these equal.
2+x = 6+0.5x Subtract 0.5x from both sides.
2+0.5x = 6 Now subtract 2 from both sides.
0.5x = 4 Finally, divide both sides by 0.5
x = 8
So in 8 years, the two trees will be the same height.</span>
Growth factor is identified as the factor by which the quantity multiplies itself over time.
Sales tax = 10.5%
Sales price = 100%
Growth factor = 100% + 10.5% = 110.5% or 1.105
The growth factor for any item purchased at your local circle mart is 1.105.
