Answer:

1/4

Step-by-step explanation:

The fraction of the juice Alisa drank was

3/8 liter

--------------------

3/2 liters

and this fraction can be simplified by inverting the divisor (3/2 liters) and multiplying instead:

3 2

------ * ----- = 2/8 or 1/4

Determine whether the relationship between the two quantities is proportional. Explain.

ira [324]

Answer:

Option B. No, because the graph of the line connecting the ordered pairs does no pass through the origin.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

step 1

Connect the ordered pairs of the graph

The y-intercept is the point (0,20)

see the attached figure

That means, that the line not passes through the origin

therefore

The relationship between the two quantities is not proportional

F(x)=5500(1.65) at what percent are the bacteria growing each hour

kodGreya [7K]

So exponenetial growth or decay

it goes like this
f(t)=P(1+r)^t
r=rate of decay or grouth
if r>0 then it is grouth by r
if r<0 then it is decay
i
P=initial amount
so
given
f(x)=5500(1.65)^t
f(x)=5500(1+0.65)^t
0.65>0 so it is growing by 65%
