Which situation represents a proportional ralationship

1 answer:

6 0

A situation represents a proportional relationship if you can write equivalent ratios of related quantities in that situation.

Step-by-step explanation:

The proportional relationships can be represented in many ways:

i) One way is considering a straight line graph passing through the origin.

ii) A verbal description describing the directly proportional relationship between two quantities.

iii) An equation y=kx, here k= constant of proportionality.

For example:

1/2 and 5/10 have a proportional relationship

Both of them are same.

The proportional relationship can help in dealing with the real life problems. Some of them are scaling a diagram, adjusting a recipe and finding increase/decrease in percentage.

Answer:

If gabe has a gift card for $50 then it will cover the cost of jeans.

Step-by-step explanation:

Given:

Gabe is buying a pair of jeans at a local store that are priced at $45.

He knows that the country he lives in has an 8% tax added onto the list price.

Now, if gabe has a gift card for $50 to get will it cover the cost of jeans.

Price of a pair of jeans = $45.

Tax = 8%.

Now, getting the amount of jeans including tax:

$45 + 8% of $45.

= $45+\frac{8}{100} \times 45$

$=45+0.08\times 45$

$=45+3.6$

$=48.6$

Thus, the amount of jeans including tax = $48.60.

As, given Gabe has gift card of $50.

Now, subtracting the amount of jeans from amount of gift card:

$50-48.60=1.40$

So, $1.40 is still remaining.

Therefore, if gabe has a gift card for $50 then it will cover the cost of jeans.

What is perimeter and area of this object?

Artist 52 [7]

Answer:

Step-by-step explanation:

You have a circle with radius r = 3 ft and a 3-by-12 rectangle.

Area of circle = πr² = 9π ft²

Area of rectangle = 3 × 12 = 36 ft²

Total area = 36 + 9π ≈ 64.3 ft²

Perimeter of circle = 2πr = 6π ft

Perimeter of rectangular projections = 18 ft

Total perimeter = 6π +18 ≈ 36.8 ft
