Answer:

3/4n + 10 = 16

Step-by-step explanation:

3/4 of a number is 3/4 multiplied by a number (3/4n); increased by 10 is the sum of ten and 3/4n; Sixteen is what 3/4n + 10 equals :)

The repeating decimal, 0.27..., is converted to the fraction 0.27..=3/x

marysya [2.9K]

Answer:

The value of x is 11.

Step-by-step explanation:

The given number is 0.27272727..., and it is converted to the fraction as

$0.272727...=\frac{3}{x}$ ..... (1)

Multiply both sides by 100.

$0.272727...\times 100=\frac{3}{x}\times 100$

$27.272727=\frac{300}{x}$ .... (2)

Subtract equation (1) from equation (2),

$27.272727-0.272727...=\frac{300}{x}-\frac{3}{x}$

$27=\frac{300-3}{x}$

Multiply both sides by x.

$27x=297$

Divide both sides by 27.

$x=\frac{297}{27}$

$x=11$

Therefore the value of x is 11.

Answer:

<h2> B and C are not independent events </h2>

Step-by-step explanation:

This is a probability question, basically on independent events.

B and C are said to be independent if the occurrence of either event does not affect the occurrence of the other.

And now considering the fact that C will always present a head any way anyhow, the occurrence

of C will affect the outcome of B and C.

<em>Hence B and C are not independent events</em>

A researcher has funds to buy enough computing power to number-crunch a problem in 5 years. Computing power per dollar doubles e

amm1812

A) In t months, the number of months required to number-crunch the problem will be
60*2^(-t/23)
By waiting t months, the researcher has made the total time f(t) to the solution of his problem be
f(t) = t + 60*2^(-t/23)

The derivative of this is
f'(t) = 1 + 60*ln(2)*(-1/23)*2^(-t/23)
We want to find the value of t that makes this be zero.
0 = 1 - 60*ln(2)/23*2^(-t/23)
2^(-t/23) = 23/(60*ln(2))
(-t/23)*ln(2) = ln(23/(60*ln(2)))
t = -23/ln(2)*ln(23/(60*ln(2))) ≈ 19.655

In order to finish his problem as soon as possible, the researcher should wait 19.7 months to buy his computers.

b) For this part of the problem, we want to find the value of "60" that makes t=0 be the solution. Taking the last expression and substituting t=0, 60=c, we get
0 = -23/ln(2)*ln(23/(c*ln(2)))
1 = 23/(c*ln(2)) . . . . . taking antilogs
c = 23/ln(2) ≈ 33.2

The largest value of c for which he should buy the computers immediately is 33.2.
