5 0

Answer:

B. 5*\frac{1}{7}

Step-by-step explanation:

5÷7 is also \frac{5}{7}--that divided sign is what the fractional bar represents in a fraction.

now multiply 5*\frac{1}{7}=\frac{5}{1}*\frac{1}{7}=\frac{5*1}{1*7}=\frac{5}{7}

both are the same result, so your answer is Choice B.

A new price of an item is $39.32. The percent increase was 16%. What was the original price?
Fiesta28 [93]

Answer:

let x =the original price

then 116x/100=$39.32

116x=100×39.32

116x=3932

116x/116=3932/116

x=33.89655

A web server hosting company advertises 99.999 percent guaranteed network uptime. (a) how many independent network servers would
miv72 [106K]
The solution for this problem would be:
Given that there is 99.999%.

Let denote n as the network servers and p as the reliability of each server.
So the probability that the network uptime = 1 - (1 - p)^n

Therefore, (1-p) ^n = 0.00001


a. x= log(1-.99999)÷log(1-.97)= 3.2833 is the answer


1-(1-.97)^3= 0.99999 + 0.0001 = 1


b. x = log(1-.99999)÷log(1-.88) = 5.43 is the answer


1-(1-.88)^3= 0.99 + 0.0001 = approx 1

4. Lee wanted to buy his mother flowers for Mother's Day. He bought 8
enot [183]

Answer:

Each tulip costs $1.50

Step-by-step explanation:

First, write an equation using the numbers given. It should look like this:

2.25(8) + 5x = 25.50

Next, multiply 2.25 by 8 to get: 18 + 5x = 25.50. Then, subtract 18 from both sides:

18 + 5x = 25.50

-18           -18

5x = 7.50

Finally, divide both sides of the equation by 5 to get $1.50

So, each tulip costs $1.50. Hope this helped!
