The equation shows a linear relationship, but not a proportional relationship.
The equation shows a linear relationship and a proportional relationship.
The equation does not show a linear relationship or a proportional relationship.
The equation shows a proportional relationship, but not a linear relationship.

Answers

The statement that is true based on the given equation is (c) The equation does not show a linear relationship or a proportional relationship.

How to determine the true statement?

The equation of the function is given as:

y = 25x^2 + 60

Linear equations can take any of the following forms

Ax + By = C

y = mx + c

y - y1 = m(x - x1)

Any equation that takes a form different from the above forms is not a linear equation

Hence, the statement that is true based on the given equation is (c) The equation does not show a linear relationship or a proportional relationship.

t is 22
A triangle is 180 degrees so you set up an equation
2t+t+26+4t=180
adding this together turns into
7t+26=180

7t=154
divide both sides by 7

At a restaurant, hot chocolate can be purchased in two different cup sizes. A 12-ounce cup costs $4.80 and a 16-ounce cup costs $6.40.

Is the linear relationship between cup size and cost also proportional? Why or why not?

Yes, there is no constant of proportionality.
Yes, the constant of proportionality is 0.4.
No, the constant of proportionality is 0.4.
No, there is no constant of proportionality.

Answers

Answer:

Yes, the constant of proportionality is 0.4.

Step-by-step explanation:

[tex] \frac{4.80}{12} = \frac{48}{120} = \frac{2}{5} = .4[/tex]

[tex] \frac{6.40}{16} = \frac{64}{160} = \frac{2}{5} = .4[/tex]

Yes, the given relation is proportional with a constant of proportionality is 0.4 thus option (B) is correct.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

A 12-ounce cup costs $4.80.

The ratio of cost to ounce = 4.80/12 = 0.4

A 16-ounce cup costs $6.40.

The ratio of cost to ounce = 6.40/16 = 0.4

So constant of proportionality is 2.5.

Hence "Yes, the given relation is proportional with a constant of proportionality is 0.4".

Suppose a hurricane traveled 130 miles from point in the Atlantic Ocean to Florida coastline in 6 1/2 hours. How many miles per hour did the hurricane travel?

Answers

Answer:

The hurricane traveled 260 miles per hour.

Step-by-step explanation:

Given,

Distance covered by hurricane = 130 miles

Then time = [tex]\frac{6}{12}[/tex] hours=[tex]0.5[/tex] hour

Distance=Speed*Time

Speed=[tex]\frac{Distance}{Time}[/tex]
Speed=[tex]\frac{130}{0.5}[/tex]

Speed=260 miles per hour

So, the hurricane traveled 260 miles per hour

speed = 170 mph
