each of the variables a, b, c, d, e and f represents a different positive real number. given the equations below, which variable

slega [8]

Answer:

The greatest value is "e"

Step-by-step explanation:

We have the following equations:

a. 1.31 a = f

b. 1.12b=f

c. 1.01c=f

d. 0.98d=f

e. 0.31e =f

Then solving for "a", "b", "c", "d" and "e" we have:

a. a = f /1.31

b. b=f/1.12

c. c=f /1.01

d. d=f / 0.98

e. e=f / 0.31

Now, given that in all the equations "f" represents the same number, the gratest value it's going to be the option in which "f" is divided by the smaller number.

The option in which f is divided by the less number is option e because, in this case, f is divided by 0.31.

How are the properties of segments and angles used to determine their measure?

zavuch27 [327]

You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.

There were 30 cookies in a jar. Eileen divided the cookies into 12 equal shares. How many cookies were there in each share?

Sedbober [7]

The answer is 2.5 cookies also known as 2 and 1/2 Because 12 can go into 30, twice , which gives us 24 and 30-24= 6 so we put a decimal point to the right of 2 and we put a 0 and bring the zero down to make 60. 12 goes into 60, 5 times so the answer is 2 1/2 or 2.5

Victoria whit used 578 kw-hr of electricity in December the rate is 9.1 cents per kw-hr find the amount of her electric bill

MatroZZZ [7]

Answer:

The amount of electricity bill is <u>$52.60</u>.

Step-by-step explanation:

Given:

Victoria whit used 578 kwh of electricity.

The rate is 9.1 cents per kw-hr.

Now, to find the amount of her electric bill.

Electricity used = 578 kwh.

Rate of electricity = 9.1 cents per kw-hr.

So, to get the amount we multiply the electricity used by the rate of electricity:

$Amount\ of\ electric\ bill=Electricity\ used\times rate\ of\ electricity$

$Amount\ of\ electric\ bill=578\ kwh\times 9.1\ cents$

$Amount\ of\ electric\ bill=5259.8\ cents.$

Thus, the amount of electricity bill = 5259.8 cents.

Now, converting the amount from cents to $ by dividing:

$1 = 100 cents.

So, 5259.8 cents ÷ 100 = $52.60 .

therefore, the amount of electricity bill is $52.60.
