Alchen [17]

Answer:

The difference between their bonus is £2.60

Step-by-step explanation:

The bonus Tom receives is 30% of £96

Tom's bonus

=  \frac{30}{100}  \times 96

= 28.8

So the bonus Tom received is £28.8

From the question, Sally gets a bonus of £31.40

This given by:

£31.40 -£28.8=£2.60

Find the value of X round your number to the nearest tenths<br><br><br> Explain it please
Anarel [89]

In this case, we must use trigonometry to find the value of x:

        tan(\alpha )=\frac{side-opposite-angle}{side-beside-angle} \\tan(70) = \frac{x}{3} \\3*tan(70) = x\\x = 3*tan(70)\\x = 8.24

Thus the value of x rounded to the nearest tenth is <u>8.2</u>

<u></u>

Hope that helps!
