What is 8 minus the product of 9 and r?

If we assume that "r" is unknown: -9r+8 or 8-9r It cannot be simplified further.


Find the possible value or values of r in the quadratic equation r2 -7r - 8 0?

I think you mean r2 -7r -8 = 0. If so, then factor it: (r+1)(r-8) = 0 Then set r+1 = 0, r+1-1=-1, r = -1 Set r-8 =0, r-8+8 = 8 so r = 8


What is one-eighth of r?

If the compound interest accrued on an amount of Rs 15000 in two years in Rs 2496 what is the rate of interest pcpa?

The total value after 2 years is 15000 + 2496 = 17496.So 17496 = 15000*(1 + r/100)2That is, (1 + r/100)2= 17496/15000 = 1.1664(1 + r/100) = sqrt(1.1664) = 1.08so r = 8% pa.The total value after 2 years is 15000 + 2496 = 17496.So 17496 = 15000*(1 + r/100)2That is, (1 + r/100)2= 17496/15000 = 1.1664(1 + r/100) = sqrt(1.1664) = 1.08so r = 8% pa.The total value after 2 years is 15000 + 2496 = 17496.So 17496 = 15000*(1 + r/100)2That is, (1 + r/100)2= 17496/15000 = 1.1664(1 + r/100) = sqrt(1.1664) = 1.08so r = 8% pa.The total value after 2 years is 15000 + 2496 = 17496.So 17496 = 15000*(1 + r/100)2That is, (1 + r/100)2= 17496/15000 = 1.1664(1 + r/100) = sqrt(1.1664) = 1.08so r = 8% pa.


Find the smallest number in a GP whose sum is 38 and product 1728?

Let the three numbers in GP: a/r, a, ar---------(A)Where '^' is power of . . .Sum of these numbers are:a/r +a +ar = 38a(1\r+1+r) = 38 ---- (1)Product of these numbers are:a^3 = 1728= (12)^3a = 12Putting the value of a in (1) you will get:12(1\r+1+r) = 38And factorising, we getr = 2/3 or r = 3/2Sub. the r and a value in (A), we get8,12,18 or 18,12,8. When a = 12And smallest no. is 8.

How do you convert 78 to a decimal?

78.0 Or do you mean 7/8 ( Seven Eights) In which case. 8)7.0000 = Eight into seven will not go . So '0' in the answerm followed by a decimal point 8)700000 =( 0. Then eight into 70 = 8 remainder 6' Hence 8)70000 - 64 R 6. ( = 0.8 > 8)6000 = Eight into 60 = 7 Remainder 4. Hence 8)40000 - 5 R 0 = ) 0.875 The answer. Hence 8)60000 - 56 R 4 = ) 0.87
