Answer the question correctly for good luck
1 answer:
Answer:
- The equation connecting c and d is: c = kd
- The value of c when d=8 is: 48
- The value of d when c=54 is: 9
Step-by-step explanation:
Proportion can be defined as the effect of changing one quantity on the other.
Given that
‘c’ is directly proportional to‘d’
It can mathematically be written as:
c∝d
A constant is introduced in the equation when the proportionality symbol will be removed. The constant is called constant of proportionality
Given that
c = 24 when d = 4
Putting the values
Putting the value of k
Putting d = 8
Putting c = 54
Hence,
- The equation connecting c and d is: c = kd
- The value of c when d=8 is: 48
- The value of d when c=54 is: 9

Step-by-step explanation:
Notice how each congruent square is divided into four equal parts. Since each square has four parts and there are four squares, there are of these parts in total. Because each of these parts make up
of each square, all parts are equal. Therefore, you can count the total number of shaded parts to get your percentage.
The top left and bottom right both have one part shaded each for a total of parts.
The top right and bottom left have and
parts shaded, respectively, for a total of
parts.
Therefore, in total, there are parts shaded out of
total parts.
Thus, the percentage of the total area that is shaded is:
