Answer:
Step-by-step explanation:
Represent Celsius with C and Fahrenheit with F.
So, we have:
Solving (a): Represent as a linear equation
First, we calculate the slope:
This gives:
The linear equation is then calculated using:
Where
Make F the subject
Solving (b): The value of F when C = 30
Substitute 30 for C in
Answer:
Step-by-step explanation:
We have been given that on a compass, due east is a 1/4 turn clockwise from due north.
Since we know that a compass is in form of a circle and the measure of degrees in a circle is 360 degrees.
To find the number of degrees in a one-fourth turn, we will divide 360 by 4.
Therefore, there are 90 degrees in a 1/4 turn of compass.
Question 4 is d question 3 is c
Answer:
Step-by-step explanation:
If two values are inversely proportional, their product must be maintained. That way, if one value goes up, the other goes down by the same extent.
Therefore, if and vary inversely, their product will be the same for all values of and .
Let and as given in the problem. Substitute values:
Hence, the maintained product is .
Thus, we have the following equation:
Substitute to find the value of when :
