Which of the following formulas correctly solves for F?
F = 9 over 5C + 32
F = 9 over 5C − 32
F = 9C + 32 over 5
F = 9C − 32 over 5
Answer:
Option 1 - F = 9 over 5C + 32
Step-by-step explanation:
Given : The equation below shows the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F:
C = 5 over 9(F − 32)
To find : Which of the following formulas correctly solves for F?
Solution :
We can write the equation as
Now, we solve for F,
Multiply both side by 9,
Open the brackets,
Divide both side by 5,
Solve,
So, The value of F is F=9 over 5C +32.
Therefore, Option 1 is correct.

$431.85
$249.85
$396.85
$492.75
Answer: Swimming will cost $431.85 for Marla (per year).
Step-by-step explanation:
Hi, to solve this we have to calculate how many weeks are in a year:
If a year has 365 days, we have to divide it by 7 ( the number of days in a week)
So: 365 / 7 =52.14 = 52 weeks
Now, with the information given we have to multiply the number of weeks by the cost per visit multiplied by 2 ( because marla swims twice a week) and add the quipment cost ($32.85) and the membership cost ($35).
Mathematically speaking:
$3.50 x 2 x 52 w + $32.85 + $35 =
$364 + $32.85 + $35 =$431.85
In conclusion, swimming will cost $431.85 for Marla (per year).
Answer:
Step-by-step explanation:
If I'm understanding this correctly, your problem is as follows:
The area of a circle is given by the formula
The area of the circle is changing at a rate of . Find the rate of change of the radius, , when r = 8.
Assuming that is what you are asking, we will begin by finding the derivative of the area of a circle using implicit differentiation.
Filling in what we have:
which simplifies a bit to
Divide both sides by 16π to get:
The π's cancel leaving the rate of change of the radius as
inches per second
In system A, the first equation multiply by 4
8x - 4y = 12 (1st)
3x + 4y = 10 (2nd)
--------------------add
11x = 22
So answer is B.
