If we divide the 7th term by the third it gives us r^4   (  common ratio to power 4).

r^4 = 7104/444 =   16

so r =  4th root of 16  = 2

So 6th term will be the 7th term / 2 = 7104 / 2 =  3552

Given the value of t3 and t7, and t7 = t3 * r^4, where r represents the geometric quotient. 

So 7104 = 444 * r^4 -> solve for r, you will get r = 2 or -2

So, for r = 2, t6 = t7 / r = 7104 / 2 = 3552

For r = -2, t6 = -3552

1 litre is approximately 1.75 pints, 1 gallon = 8 pints, calculate the approcimate number of gallons that are equal to 48000cm3
Umnica [9.8K]

Answer:

10.5\ gal

Step-by-step explanation:

we know that

1,000\ cm^{3} =1\ l

1\ l=1.75\ pints

1\ gal=8\ pints

we have

48,000\ cm^{3}

step 1

Convert to liters

48,000\ cm^{3}=48,000/1,000=48\ l

step 2

Convert to pints

48\ l=48*1.75=84\ pints

step 3

Convert to gallons

84\ pints=84/8=10.5\ gal

Find the value of the expression 3m^2+2p^2-15 when m =3 and p = 10
mylen [45]

3m {}^{2}  +  {2p}^{2}  - 15
m = 3
p = 10

3 \times 3 {}^{2}  + 2 \times  {10}^{2}  - 15 =
3 \times 9 + 2 \times 100 - 15 =
27 + 200 - 15 =
212

Hence, the answer is 212.
