Select Proportional or Not Proportional to correctly classify each pair of ratios. Proportional Not Proportional 12/30 and 18/45 O O

Answers

Answer 1
Answer: 12/30 = 18/45....cross multiply
(30)(18) = (12)(45)
540 = 540...proportional

another way to tell is to see if they are equivalent...because proportions are nothing but equivalent fractions.
12/30 = 2/5
18/45 = 2/5
so yes, they are proportional
Answer 2
Answer:

12/30 = 18/45, so first you're going to cross multiply and you'll get (30)(18) = (12)(45). Then you can see that 540 = 540 same number so they're proportional...

BTW THIS WAY IS A LOT EASIER.

12/30 = 2/5

18/45 = 2/5

So yes, in summary, they're proportional to each other. Hope this helps, have a BLESSED and wonderful day! :-)

Answers

Answer:

c) 286

Step-by-step explanation:

Since Annabelle paid 200 euros

And Myra wants to pay Annabelle back in U.S. dollars.

Let Myra paid amount to Annabelle in U.S. dollar be x

\frac{1}{0.7}=\frac{x}{200}

⇒\frac{1*200}{0.7}=x

⇒\frac{200}{0.7}=x

⇒285.7=x

⇒285.7≈286

What is co-ordinate geometry?

Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.

Given:

The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.

A figure is in quadrant IV. the figure is reflected in the y-axis.

The rule for a reflection over the y -axis is (x,y)→(−x,y) .

The image is reflected in III quadrant.

∴(x,-y)→(−x,-y) .

Therefore, the image is reflected in III quadrant.

well for 3.  you use the Pythagorean theorem to say that 28^2 - 18^2= x^2 so 21.4  and for 4. the Pythagorean theorem says a^2 + b^2 = c^2 with c being the hypotenuse of any right triangle so the sums of the two smaller squares make the sum of the larger square making the answer b 

11/14-?/4=4/14 show the missing number

Answers

Hey there, we keep the denominators the same because they are both common denominators, (14). 11-4=7, Therefore, the missing number is 7 because 11/14-7/14=4/14
the missing number is 2/4.
11/14 - 2/4 = 4/14.
