Answer:
£480
Step-by-step explanation:
x = the original price of a computer
£x = 100% of the original price
The price of a computer was decreased by 30% to £336.
This means:
£336 = 100% - 30%
£336 = 70% of the original price
From this, we will find 1% of the original price.
£336 ÷ 70 = 1%
£4.8 = 1%
Since the original price ( x ) = 100% of the original price, we will find 100% of the original price.
£4.8 × 100 = 100%
£480 = 100%
Therefore, the original price of a computer = £480

<span>The <u>correct answer</u> is:
$64.
Explanation<span>:
We will mulitiply the first two numbers first.
We will first write 1200 as a fraction by putting it over 1:
1200/1 * 8/100.
We now multiply straight across: (1200*8)/(1*100) = 9600/100 = 96.
Now we will multiply this by the last fraction. Again we will make the whole number, 96, a fraction by placing it over 1:
(96/1)*(240/360).
Again we multiply straight across: (96*240)/(1*360)=23040/360.
When we divide this out, we get 64.</span></span>
Answer:
tan(θ) = 0, 0.577, -0.577
Step-by-step explanation:
3tan³(θ) - tan(θ) = 0
tan(θ)(3tan²(θ) - 1) = 0
tan(θ) = 0
tan²(θ) = ⅓ tan(θ) = +/- sqrt(⅓)
tan(θ) = 0, sqrt(⅓), -sqrt(⅓)
tan(θ) = 0, 0.577, -0.577
To find θ values, domain is required
