Answer:

  $3.05

Step-by-step explanation:

Let b represent the one-way bus fare. Then Carly's expenses were ...

  8.25 + 3.85 + 2b = 18.20

  2b = 6.10 . . . . subtract 12.10

  b = 3.05 . . . . . divide by 2

Carly spent $3.05 on bus fare each way.

f(x) = 20(1.5)x. Let your dependent variable in the function be y. Write the function that models the independent variable in te
mars1129 [50]

Answer:

x=log_{1.5}(\frac{y}{20})

Step-by-step explanation:

Considering the function:

f(x) = 20\, (1.5)^x

The independent variable is "x" and we are asked to model it in terms of the variable "y":

f(x) = 20\, (1.5)^x\\y=20\, (1.5)^x

Then, in order to solve for x (which resides in the exponent), we need to use the logarithm function.

Since the base of the exponent is 1.5, we need to use the logarithm base 1.5, to lower that exponent "x":

y=20\, (1.5)^x\\\frac{y}{20} =(1.5)^x\\log_{1.5}(\frac{y}{20}) =x\\x=log_{1.5}(\frac{y}{20})

A number is greater than 50 and less than 85 the number has 13 and 3 as factors
alina1380 [7]

Answer:

The Answer is: 78.

Step-by-step explanation:

This one makes you think!

Let n = the number.

The number is greater than 50 and less than 85:

50 < n < 85

Some of the factors are 13 and 3.

So, multiply 13 * 3 = 39.

Multiply again by 2:

39 * 2 = 78.

78 can be factored as:

13 * 3 * 2 = 78, and it is greater than 50 and less than 85.

The number is 78.

Hope this helps! Have an Awesome Day!! :-)

Is the least common multiple of a pair of numbers ever less than both numbers
nadezda [96]

well It never could be less than both numbers. the LCM of 2 numbers shd either be greater than the 2 numbers .... or the answer should be equal to either one of the numbers ...

lets see some examples to prove this conclusion:

now, lets find the LCM of 2 and 6 ... so if we do it ... we get the answer 6 .. which is ..as we said equal to one of the numbers

another example : 5 and 7 ... in this ... if we do it .. .we get the LCM as 37 ... which is greater than both the numbers

another case where both the numbers are same ....

where we need to find the LCM of 7 and 7 ... the answer will be 7 itself .....
