The sum of Ellie’s ages an Genya’s age is 60. In 6 years, genus will be 8 times as old as Ellie. How old is Ellie now?

Aleonysh [2.5K]

Ellie's age = 58 years

Genya's age = 2 years

Step-by-step explanation:

Let e represent Ellie's age

and

g be Genya's Age

Then

$e+g = 60\ \ \ Eqn1$

In six years

Ellie will be e+6 years old and Genya will be g+6 years old

then

$g+6 = 8(e+6)\\g+6 = 8e+48\\g = 8e+48-6\\g = 8e+42\ \ \ Eqn2$

Putting g= 8e+42 in equation 1

$e+8e+42 = 60\\9e +42 -42 = 60-42\\9e = 18$

Dividing both sides by 9

$\frac{9e}{9} = \frac{18}{9}\\e=2$

Putting e = 2 in equation 1

$e+g = 60\\2+g = 60\\g = 60-2\\g = 58$

Hence,

Ellie's age = 58 years

Genya's age = 2 years

Tobias sent a chain letter to his friends, asking them to forward the letter to more friends. The number of people who receive t

dybincka [34]

Answer:

$P(t)=37\cdot 4^{t/9.1}$

Explanation:

This is an exponential growing: there is a constant growing factor which multiplies the value number of letters sent every week.

The growing factor 4 letters every 9.1 weeks means that every 9.1 weeks the number of letters is multiplied by 4.

Then, if the number of weeks is t, the number of times the number of letters increase is t/9.1.

Then, the exponential function that models the number of people who receive the email t weeks since Tobias initially sent the chain letter, has the form:

$P(t)=Initial\text{ }value\cdot 4^{(t/9.1)}$

Tobias initially sent the chain letter to 37 friends; thus, the initial value is 37, and the complete function is:

$P(t)=37\cdot 4^{t/9.1}$ , where t is the number of weeks since Tobias initially sent the chain letter.

To bill customers for water usage, one city converts the number of gallons used into units. This relationship is represented

-Dominant- [34]

Answer:

g is the independent variable.

u is the independent variable.

Step-by-step explanation:

According to the question, the data mentioned is as follows

Equation g = 748u

where,

g = the total number of gallons of water used

And, u = the number of units.

As we've seen, Consumers are using the number of units of water.

The volume of water units does not depend on the total quantity of gallons of water that is being used.

So, the number of units i.e u represents an independent variable.

hence,

The value of the total quantity of gallons is entirely dependent on the number of units used, and the g represents the dependent variable

Therefore,

The third and fourth option is correct
