Answer:

2a²

Step-by-step explanation:

Pair 'like' terms with 'like' terms, ie numbers go with numbers, and 'a's go with 'a's.

Lets deal with the top of the fraction first:

4ax3a³

Rearrange it so you have numbers beside numbers and 'a's beside 'a's:

(4x3)x(axa³)

12x(a⁴) <em>(because nᵃxnᵇ=nᵃ⁺ᵇ)</em>

12a⁴

Now, instead of (4ax3a³)/6a², we have 12a⁴/6a²

First divide the numbers: 12/6 =2

Now divide the 'a' parts: a⁴/a²=a² <em>(because nᵃ/nᵇ=nᵃ⁻ᵇ)</em>

Now we have 2a²

Answer:

<h2>a) 24.39</h2><h2>b) 13.78</h2><h2>c) 7.92</h2><h2>d) expanding the business.</h2><h2>h) \frac{1}{5}</h2>

Step-by-step explanation:

a) The growing percentage for delivery of packages is \frac{5.1 - 4.1}{4.1} \times100 = \frac{10\times100}{41} = 24.39

b) The required percentage is \frac{454000 - 399000}{399000} \times100 = \frac{55000}{399000}  \times100 = 13.78(approximately)

c) Delivery vehicles has grown by \frac{119000 - 101000}{101000} \times100 = \frac{8000}{101000} \times100 = 7.921(approximately)

d) As it is cleared that UPS has increased the values with time, it can be possible that It was expanding with time.

e), f) and g) has shown in the given image.

h) The slope is \frac{5.1 - 4.1}{2017 - 2012} = \frac{1}{5}

Here the slope means the change of number of packages with time.

Answer:

189

Step-by-step explanation:

Since the series is geometric with common ratio r, then

r = 6 ÷ 3 = 2

The terms in the series are twice the previous term, that is the series is

3 + 6 + 12 + 24 + 48 + 96 ← summing the terms gives

sum = 189
