Step-by-step explanation:

from Lami's theorem:

\frac{7}{ \sin(40 \degree) }  =  \frac{x}{ \sin(81 \degree) }  \\  \\ x =  \frac{7 \sin(81 \degree) }{ \sin(40 \degree) }  \\  \\ x = 10.8 \: cm

Step-by-step explanation:

\frac{ \sin(81) }{x}  =  \frac{ \sin(40) }{7}  \\ x  \times \sin(40)  = 7 \times  \sin(81)  \\ x =  \frac{7 \times  \sin(81) }{ \sin(40) }  = 10.75 = 10.8 \: cm

What is the next two term in the sequence 6, 10, 14, 16
8090 [49]

Answer:

  • Next two terms of the sequence is 20 and 24.

Step-by-step explanation:

The arithmetic sequence is 6, 10, 14 , 16

First term (a) = 6

Subtract the first term from the second term:

  • 10 - 6 = 4

Subtract the second term form the third term:

  • 14 - 10 = 4

Subtract the third term from the Fourth term:

  • 16 - 14 = 4

Here, You will notice that each time you move from one number to the next one it increases by four. So, the difference between one and the next term is four.

So,

Next two terms are:

⟶ 16 + 4 = 20

⟶ 20 + 4 = 24

Hence,

  • <u>Next two terms of the sequence is 20 and 24.</u>

Ed buys a box of eggs costing £2.80, two packs of bacon for £2.40 each and two tins of baked beans. He pays with a £10 note and
guajiro [1.7K]

Answer:

£0.8

Step-by-step explanation:

egg = 2.80

Bacon = 2 * 2.40 = 4.80

Baked beans = 2 tins

Amount issued = 10

Change obtained = 80p = 0.8

Let cost per baked beans = x

Hence,

2.80 + 4.80 + 2x = 10 - 0.8

7.60 + 2x = 9.20

2x = 9.20 - 7.60

2x = 1.6

x = 1.6 / 2

x = 0.8

Hence, a tin of baked beans cost £0.8
