This is a simple one. we have the base price of 14 dollars for renting the boat. We also have an unknown number for the number of hours we decide to rent this boat.

The equation would be 14×h=c

HOPE THIS HELPED. HOPE YOU CAN GIVE ME A <em><u>5</u></em><em><u> </u></em><em><u>STAR</u></em><em><u> </u></em><em><u>RATING</u></em><em><u>,</u></em><em><u> </u></em><em><u>A</u></em><em><u> </u></em><em><u>HEART</u></em><em><u>,</u></em><em><u> </u></em><em><u>AND</u></em><em><u> </u></em><em><u>PUT</u></em><em><u> </u></em><em><u>THIS</u></em><em><u> </u></em><em><u>ANSWER</u></em><em><u> </u></em><em><u>AS</u></em><em><u> </u></em><em><u>THE</u></em><em><u> </u></em><em><u>BRAINLIEST</u></em><em><u> </u></em>THAT WOULD BE VERY MUCH APRECIATED!!!

Nat2105 [25]

Answer:

  $4127

Step-by-step explanation:

The amortization formula is good for finding this value.

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the amount invested at rate r for t years.

  A = $600,000(0.055/12)/(1 -(1 +0.055/12)^(-12·20)) = $4127.32

You will be able to withdraw $4127 monthly for 20 years.

Biologists have found that the number of chirps some types of cricket make per minute depends upon the temperature this relation
Alex Ar [27]

Answer: Crickets make 172 chirps/min at 80 degrees Fahrenheit

Step-by-step explanation:

Step 1

Using the point slope formulae for Linear functions , we have that

y - y1 = m(x - x1)

where x  and y are two points  representing the  temperature and chirps /min respectively

And  

m= slope

Step 2 : Finding the slope , m

where x1=60

           y1=92

           x2= 75

           y2=152

m= (y2-y1)/ (x2-x1)

= (152- 92)/(75-60)

=60/15 =4

Bringing down the point/slope formula and imputing the known values to find our equation to show the relationship cricket make per minute and  the temperature

y - y1 = m(x - x1)

y - 92= 4(x - 60)

y - 92 = 4x -240

y = 4x - 240 + 92

y = 4x - 148

Step 3

To find the number of chirps be per minute (y) if the temperature is 80 degrees Fahrenheit( x)

y = 4(80) - 160

y = 320 - 148

y = 172 chirps/min at 80 degrees Fahrenheit

Find an equation of variation in which y varies jointly as x and z and inversely as the product of w and​ p, where yequalsstartf
leva [86]

To solve this problem you must apply the proccedure shown below:

1. You have that y varies jointly as x and z and inversely as the product of w and​ p. Therefore, you can write the following equation, where k is the constant of proportionality:

y=k(\frac{xz}{wp} )

2. Now, you must solve for the constant of proportionality, as following:

k=\frac{ywp}{xz}

3. Susbtiute values:

y=\frac{7}{28} \\ x=7\\ z=4\\ w=7\\ p=8

k=\frac{(\frac{7}{28})(7)(8))}{(7)(4)}  =0.5

4. Substitute the value of the constant of proportionality into the equation:

y=0.5(\frac{xz}{wp})

The answer is: y=0.5(\frac{xz}{wp})

How do you evaluate 3ab
dimaraw [331]
Lets say a=2 and b=5  you now plug in you numbers to get 3x2x5 we know 3x2=6 so now take 6 and multiply it by 5 so 6x5=30  you can also set this equal to 0 3ab=0 then divide by either a or b ill show you both if you divide by a you are left with 3b=a if you divide by b than you get 3a=b
