Question

Q8a)i-Write down the degree of polynomial: xy - yz + 2x
ii-Write down the number of terms in: 6 + xy.
ii)-Write down the coefficient of p in -px.
08b) Find the ratio of 7.80 to 65 paise in simplest form.
Q8c) Find the H.C.F of 147, 210 and 294​

Answer 1

Answer:

I) Degree of polynomial : 2

II) No. of terms : 2

III) Simplest form of ratio 7.80₹ to 65 paise = 12:1

IV) HCF of 147, 210, 294 is 7

Step-by-step explanation:

I) In first term power is = x¹y¹ = 2

II) 6 & xy are two different terms.

III)

1₹ = 100 paise

Therefore, 7.80 = 7*100 + 80

= 780

Ratio of 780 to 65 = 780 / 65

= 65 * 12 / 65 * 1

= 12 / 1

= 12 : 1

IV) 147 = 2 * 7 * 7

210 = 2 * 3 * 5 * 7

294 = 2 * 3 * 7 * 7

Therefore, common multiple is 7
