A = \frac{1}{2} ab sin C

QPR contains two sides and the included angle

XYZ has one side and the two angles

DEF has only three sides

Dr yang buys a violin for £13200 plus vat at 20% dr yang pays a deposit for the violin he then pays the rest of the cost in 12 e
Andre45 [30]

Answer:

8/3

Step-by-step explanation:

Given that:

Cost of violin = 13200 plus VAT at 20%

Cost of violin = (100 + 20)% * 13200

Cost of violin = 1.20 * 13200 = £15,840

Instalment pay = (360 * 12) = 4320

Therefore, deposit made equals ;

Total cost - Instalment pay

£(15,840 - 4320) = £11,520

Hence, ratio of deposit made to the total Instalment payment made ;

£11520 / £4320 = 8 / 3

Write a linear equation. Choose three input values and find the corresponding output values. Show your work.
erma4kov [3.2K]

Example of linear equation:

y = mx + b

Let's have the linear equation;

y = 2x + 3

<h3 /><h3>Put x=1</h3>

y = 2 \times 1 + 3  \\ y = 2 + 3 \\ y = 5

(x,y) = (1,5)

<h3>Put x=2</h3>

y = 2 \times 2 + 3 \\ y = 4 + 3 \\ y = 7

(x,y) = (2,7)

<h3>Put x=3</h3>

y = 2 \times 3 + 3 \\ y = 6 + 3 \\ y = 9

(x,y) = (3,9)

Nitella [24]

Answer:

244.80 If I'm not wrong.

Step-by-step explanation:

Add all of the deductions together and subtract them by 880

By using g00gle I found out that 195.82 + 63.60 + 134.64 + 176.00 = 635.24.

So now you subtract it by her salary down below:

880.00 - 635.24 = 244.76  

244.80 or 245 if I'm not wrong
