The difference of two numbers is 44 1/2 . If the smaller of the two numbers increases 7 times then the difference will be 10 3/1

Kobotan [32]

Answer: The smaller number is 9 and 5/42. The larger number is 53 and 13/21.

To find these answer you have to write the following two equations.

x - y = 44 and 1/2
7y - x = 10 and 3/14

Then, you can use the substitution method to solve them. Change the first equation to: x = 44 + y. Substitute that into the second equation and solve for y. Once you have that, plug it back into the first equation and solve for x.

For a given geometric sequence, the 9th term, a9, is equal to 43/256 and the 14th term, a14, is equal to 172. Find the value of

EastWind [94]

Answer:

$18th=44032$

Step-by-step explanation:

From the question we are told that:

9th term $a9=\frac{43}{256}$

14th term $a14=172$

Generally the equation for Geometric sequence is mathematically given by

$a_n=a_1r^{n-1}$

For 9th term

$\frac{43}{256}=a_1r^{8}$

For 14th term

$172=a_1r^{13} \\a_1=\frac{172}{r^13}$

Substitute in 9th term

$\frac{43}{256}=\frac{172}{r^13}*r^{8}$

$\frac{43}{256*172}=r^{-5}$

$r=^5sqrt{\frac{44032}{43}}$

$r=4$

Therefore First term a is given as

$a_1=\frac{172}{4^13}$

$a_1=2.563*10^{-6}$

Generally the equation for the 18th term is mathematically given by

$18th=a_1r^{17}$

$18th=2.563*10^{-6}*4^{17}$

$18th=44032$

Find the value of 0.16÷0.064<br>

irina1246 [14]

This is a division we can write those numbers as fractions to make it simpler

0.16= $\frac{16}{100}$

0.064= $\frac{64}{1000}$

when we divide two fractions we can multiply the divided with the inverse divisor

$\frac{16}{100}*\frac{1000}{64}$

we simplify

$\frac{1}{1} *\frac{10}{4}$

which is equal to

$\frac{10}{4}$

or

$\frac{5}{2}$

we can leave it like this or divde to get
