Question Help Writing Suppose the relationship between x and y is proportional. When x is 29, y is 275.5. Find the
constant of proportionality of y to x. Use the constant of proportionality to find x when y is 408.5. Use
pencil and paper. Explain how you can tell a relationship that is proportional from a relationship that is
not proportional.
The constant of proportionality is I.
(Type a whole number or a decimal.)

a) I=9,5

b) x=43

c) I is same for every  value of y and x if the relationship is proportional.

Step-by-step explanation:

The constant of proportionality I can be found as:

a)

We are given: x= 29, y=275.5 we need to find constant of proportionality I

Using formula:

So, constant of proportionality I = 9.5

b)

Now, we need to find x when y is 408.5.

Using the above formula we can find x

c)

A relationship is proportional if for every value of x and y we have a relation: where I is constant. The value of I is same for every value of y and x.

If a relationship is not proportional then for every value of x and y we have don't have a relation: where I is constant. The value of I is different for every value of y and x.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

answer:

your answer is: c. 196 7/8 in^3.
