Answer:

$4.25

Step-by-step explanation:

Let price of drink be x

price of tub y

You have 4x+2y=32.5 (1) and

x = y -3.5 (2)

Plug for x from (2) into (1):

4(y-3.5) + 2y = 32.5

4y -14 +2y = 32.5

6y = 14+32.5

y = (46.5)/6 = $7.75 the price of tub

x= y-3.5 = 7.75 - 3.5 = $4.25

-1/2 divided by 1 3/4 as a fraction in simplest form

$-\displaystyle\frac{1}{2} :1\frac{3}{4}$

First , convert the mixed number (the fraction we are dividing by in the given maths problem) into an improper fraction .

Multiply the whole part (1) times the denominator (4) and add the numerator . The result is the numerator of our fraction , and the denominator stays the same .

So now our maths problem looks as follows :

$-\displaystyle\frac{1}{2} :\frac{7}{4}$

Now turn the fraction you are dividing by over :

$-\displaystyle\frac{1}{2} *\frac{4}{7}$

Now multiply the numerator of the first fraction times the numerator of the second fraction :

Perform the same operation with the denominators :

-4/14

So the result is :

$-\displaystyle\frac{4}{14}$

Since the above fraction is not in it's simplest form , we divide the top and bottom by 2 (a common factor of both 4 and 14) :

$-\displaystyle\frac{2}{7}$

From an elevation of 3.5m below the surface of the water, a northern bottle nose whale dives at a rate of 1.8m/s.Write a rule th

Nookie1986 [14]

Answer:

$d(t)=-108*t-3.5$ .

435.5 meters below water surface.

Step-by-step explanation:

We have been given that from an elevation of 3.5 m below the surface of the water. A northern bottle nose whale dives at a rate of 1.8 m/s.

Let us convert whale's dive rate in terms of meters per minute.

Since we know that 1 minute=60 seconds so we will multiply whale's dive rate by 60 to convert it in meters per minute.

$1.8\frac{\text{meters}}{\text{second}} =1.8*60\frac{\text{meters}}{\text{minute}}$

$108\frac{\text{meters}}{\text{minute}}$

We can write a rule that gives the whale's depth d as a function of time in minutes as:

$d(t)=-108t-3.5$

Therefore, our function will be $d(t)=-108*t-3.5$ .

Now let us find whale's depth after 4 minutes by substituting t=4 in our function.

$d(4)=-108*4-3.5$

$d(4)=-432-3.5$

$d(4)=-435.5$

Therefore, after 4 minutes whale will be 435.5 meters below water surface.
