Is the relationship between the number of slices of salami in a sandwich and the number of calories proportional? explain.

slices of salami | calories

1 | 66
2 | 96

3 | 126

4 | 156

The number of slices of salami and the number of calories are not proportional

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x -----> the number of slices of salami

y ----> the number of calories

Find out the value of the constant of proportionality k

For (1,66) -----> ---->

For (2,96) -----> ---->

For (3,126) -----> ---->

For (4,156) -----> ---->

The values of k are different

therefore

The number of slices of salami and the number of calories are not proportional

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

answer: 1722

step-by-step explanation:

given: the mass of saturn=

the mass of mercury=

the number of times the mass of saturn is greater than the mass of mercury

hence, the mass of saturn is 1722 times greater than the mass of mercury.
