Amanda and Katie are twins. At birth, Amanda was 6 3/10 pounds and Katie was 5 9/10 pounds. What is their combined birth weight?

Answers

Answer:

10 2/10

Step-by-step explanation:

because together it equals 9 12/10 but that cant happen so you add 1 to the 9 and get 10 so you have 2 left over

12.2 or 12 1/5

6 + 5 = 11
3/10 + 9/10 = 12/10
11 + 1 = 12 + 2/10
simplified is 1/5

12 1/5

Which graph
or equation represents a nonproportional relationship?

Answers

Answer:

The equation that represents a proportional relationship must have this form:

y=mx

And the graph of a proportional relationship must be a a line that passes thorugh the origin.

Step-by-step explanation:

Since the graph is not attached, I will give you a general explanation about how to solve the exercise.

The equation of a line that passes through  the origin is the following:

y=mx

Where "m" is the slope of the line.

The proportional relationships have the following form:

y=kx

Where "k" is the Constant of proportionality.

Therefore, the graph of proportional relationships is a line that passes through the origin.

Therefore the equation that represents a proportional relationship must have this form:

y=mx

And the graph is a a line that passes thorugh the point (0,0)

Final answer:

A nonproportional relationship is represented by equations or graphs in which the ratio of the variables does not remain constant, like the equation y = x².

Explanation:

A nonproportional relationship is one in which the ratio between the two variables does not remain constant. In terms of graphs or equations, a nonproportional relationship would not be a straight line when graphed. A simple example is the equation y = x². In this case, as x increases, y increases at a changing rate, not a constant rate, which shows it is nonproportional.

 

Furthermore, when you graph the equation y = x², it forms a parabola, not a straight line. A straight line would indicate a proportional relationship with a constant ratio, while a curve like a parabola indicates a nonproportional relationship.

If you used 3/4 of the blue paint to make flames on one of the cars, and need 7 3/4 pints of blue paint to paint another car, what amount of blue paint do you need to buy?

Answers

3/4 of 7 pints were used. of, in this case, means to multiply. 3/4 x 7= 21/4= 5 and 1/4 pints. Now we subtract 5 and 1/4 (because this is how much was used) from 7. 7- 5 and 1/2 = 1 and 1/2
