Answer:

I dont know how many pounds are in an ounce but I'll give you an explanation using kilograms and grams as an example and I'll talk you through it

Step-by-step explanation:

there are 1000 grams(g) in a kilograms (kg) just so you know

let's say I have a 13 g box of cereal for $3.99.

I do a ratio to work out 1 kg

13 g : $3.99

1000g : x

In your case your going to write

13 ounces : $3.99

[here write how many

ounces are in a pound] : x

to find x you 1st have to take the 2 numbers you do know and divide them

so in my example I do 1000g÷13 g = 76

then I take 76.92 and I multiply it by the other side

$3.99 x 76.92 = 306.91

for me 1kg of cereal is worth $306.91

all you need to do is replace my 1 kg with how many ounces are in a pound

Is the expression x3•x3•x3 equivalent to x3•3•3? Why or why not? Explain your reasoning.

Sunny_sXe [5.5K]

If the first expression reads x(cube) • x(cube) • x(cube) and x(cube • cube • cube), then the answer is no. They are not equal.

x(cube) • x(cube) • x(cube) will be equivalent to x(to the 9th power) while x(cube • cube • cube) will be equivalent to x( to the 27th power).

r Flag For Review A certain city with a population of 132,000 is to be divided into 11 voting districts, and no district is to h

Alex787 [66]

Answer:

$P = \frac{132000}{12}=11000$

So then P =11000 is the minimum that the least populated district could have.

Step-by-step explanation:

We have a big total of N = 132000 for the population.

And we know that we divide this population into 11 districts

And we have this info given "no district is to have a population that is more than 10 percent greater than the population of any other district"

Let's assume that P represent our minimum value for a district in the population. The range of possible values for the population of each district would be between P and 1.1 P

The interest on this case is find the minimum value for P and in order to do this we can assume that 1 district present the minimum and the other 10 the maximum value 1.1P in order to find which value of P satisfy this condition, and we have this:

$P + 10 (1.1P) = 12 P= 132000$
