Dana bikes 10 miles in 50 min. at this rate how far can she bike in 90 min?

1 answer:

3 0

Dana would go 18 miles in 90 minutes because she is going a mile for every five minutes, so if she bikes for another forty minutes she will have biked 8 miles. This means that you would multiply 8 miles (remember its a mile per 5 minutes) by five minutes and that would give you forty. Then just add that on to the 50 minutes she has already biked.

What are the values of K and M? And please show all work on how you got your answer

ipn [44]

Answer:

k = 7

m = 8

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, so the two halves of each diagonal are the same length. That means ...

m = 8

and

k +4 = 11

k = 7 . . . . . subtract 4 from both sides of the equation

The relationship between a bacteria population p, in thousands, and time d, in days, since it was measured to be 1,000 can be re

Assoli18 [71]

d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

<h3>What is an exponential function?</h3>

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let p represent the bacteria population in thousand after d days.

Since each day, the bacteria population grows by a factor of 2, hence:

$p=2^d$

Hence, d = log₂p represents a logarithmic function

The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

(fg)-1(5)=g-1f-1(5)

larisa86 [58]

Answer:

f = g/ g+1

Step-by-step explanation:

Remove Parenthesis.

fg - 1 x 5 = g - 1 x f - 1 x 5

Cancel -1 x 5 on both sides.

fg = g - 1 x f

Simplify 1 x f to f.

fg = g - f

Add f to both sides.

fg + f = g

Factor out the common term f.

f (g + 1) = g

Divide both sides by g + 1

f = g/ g + 1
