Plz only find the shaded area only I would appreciate if you did this on paper and showed all steps

The area of the shaded portion is 106 square m. I got this number by finding the area of the WHOLE figure (120 because that’s what 10 times 12 equals) then I subtracted that by the area of the white portion (14 because 7x2 equals that). Then I just subtract 14 from 120 and get 106. Hope this helps

Answer:

3x + 5y = 2

Step-by-step explanation:

y = -3/5 x + 2

multiply both sides by 5

5y = -3x + 2

add 3x to both sides

3x + 5y = 2

note: if it really has to be equal to 20, then multiply both sides by 10, which will result in 30x + 50y = 20

large popcorn: $8

small drink: $3.75

= $8 + $3.75

Answer:

$11.75d

Step-by-step explanation:

add 8.00 and 3.75

you get 11.75 since U don't know how much it is for the drink, then U put d 11.75 so when U find d, you'll know that U can add it with your sum.

Which rule defines S, for an = 3(0.7)n?

Sn=7(0.7n)

Sn = 2.1(0.7n)

Sn= 7(1-0.7n)

Sn= 2.1(1-0.7n)

Answers

Answer: C

Sn= 7(1-0.7n)

Step-by-step explanation:

The rule that defines S for [tex]a_n = 3(0.7)^n[/tex] is:

[tex]S_n = 7(1 - 0.7^n)[/tex]

The rule of S means that we calculate the rule that defines the sum of n terms of the geometric progression.

Given that:

[tex]a_n = 3(0.7)^n[/tex]

Rewrite as:

[tex]a_n = 3 (0.7)^n \times 1[/tex]

Replace 1 with 0.7/0.7

[tex]a_n = 3 (0.7)^n \times \frac{0.7}{0.7}[/tex]

Rewrite as:

[tex]a_n = 3 *0.7 \times \frac{(0.7)^n}{0.7}[/tex]

Apply law of indices

[tex]a_n = 3 \times 0.7 \times (0.7)^{n-1}[/tex]

[tex]a_n = 2.1 \times (0.7)^{n-1}[/tex]

The n term of a geometric progression is:

[tex]a_n = ar^{n-1}[/tex]

Compare [tex]a_n = ar^{n-1}[/tex] to [tex]a_n = 2.1 \times (0.7)^{n-1}[/tex]

[tex]a = 2.1[/tex] --- the first term

[tex]r = 0.7[/tex]

The sum of n terms of a geometric progression is:

[tex]S_n = \frac{a(1 - r^n)}{1 -r}[/tex]

This gives:

[tex]S_n = \frac{2.1(1 - 0.7^n)}{1 -0.7}[/tex]

[tex]S_n = \frac{2.1(1 - 0.7^n)}{0.3}[/tex]

[tex]S_n = 7(1 - 0.7^n)[/tex]

why is the petrol price cheaper at coastal than inland

Answers

Answer: If a litre of fuel at the coast (95 octane) costs R13,89, then 38% is tax. The difference between inland and coastal fuel prices is mainly due to transport costs of the fuel from depots at the coat to inland outlets.

The petrol price is cheaper at coastal than inland due to the cost of transporting the petrol to inland. Deposits are found along the coast, so the price to transport the petrol is much cheaper than having to transport it all the way from the coast to inland. Therefore, transportation costs are the cause of petrol prices being cheaper at the coast than it is inland.
