Answer 1
Answer:
-- I have my eye on a real spiffy car that I want to buy.

-- It costs  $5,400  and it will only be available for 4 months.

-- How much do I have to save every month if I want to
buy the car just before it disappears ?

The equation is               (4) x (Monthly saving) = $5,400 .

Divide each side by 4 :            Monthly saving = $5,400 / 4

                                           There's your division equation.

Bryan purchased two triangular wall shelves. The sides of each shelf are 8 inches, 10 inches, and 12 inches. He's trying to build a similar, larger triangular shelf to hang between the smaller ones. Which of the dimensions can Bryan use for the larger shelf so that it is similar to the ones he purchased? Justify why the three triangles are similar.A) 4 inches, 5 inches, and 6 inches; All of the side lengths of the smaller triangles have been multiplied by 1/2 which guarantees side-side-side similarity . B) 16 inches, 20 inches, and 24 inches; All of the side lengths of the smaller triangles have been multiplied by 2, which guarantees side-side-side similarity. C) 16 inches, 20 inches, and 24 inches; All of the side lengths of the smaller triangles have been multiplied by 2, which guarantees side-angle-side similarity. D) 16 inches, 20 inches, and 24 inches; All of the side lengths of the smaller triangles have been multiplied by 2, which guarantees angle-angle-side similarity.

How to add and subtract fractions

Answers

You need to find the common denominator of all of the fraction and you also have to do whatever you did to the bottom to the top. So if you times the bottom by 2 you need to times the top by two. Then once you have that you can add and subtract! 
You need to find the common denominator.

In your question : 


4 2/7 -  2 1/5
= 4/1 * 2/7 - 2/1 * 1/5
= 8/7 - 2/5 ⇒ There, the common denominator is 7 * 5 = 35
= (8*5)/(7*5) - (2*7)/(5*7)
= 40/35 - 14/35
= (40-14)/35
= 26/35

2.11. Tariff is the cost or charge for a service.

2.2.2. The cost of refilling the pool with 15kl of water is R285.90.

2.2.3. The VAT inclusive cost for 15kl is R328.79.

2.11. Tariff is the cost or charge for a particular service or resource. It can be thought of as a rate or price that is applied to a specific quantity or volume of the resource being used.

2.2.2. To calculate the cost of refilling the pool, we need to determine the amount of water required and then multiply it by the appropriate tariff rate.

In this case, 15 kilolitres of water needs to be refilled, and based on the provided tariffs, the cost would be: 15 kl x R19.06/kl = R285.90.

2.2.3. To calculate the VAT inclusive amount for using 15 kl, we need to include the value-added tax (VAT) to the cost. VAT is calculated as a percentage of the initial cost.

Assuming a VAT rate of 15%, the VAT inclusive cost would be: R285.90 + (15/100 x R285.90) = R328.79.

the answer would be option C :)

Answer:

Second diagram

Step-by-step explanation:

Basically, for any of these options to be functions, each value in the domain must correspond to only one value in the range.  So any option that has a value in the domain section with arrows pointing to multiple values in the range section is not a function, and not our answer. We must look for the option where there is only one range value for each domain value. So our answer is the second option.
