give one examples of proportion. How do you know they are proportions? Then give three non-examples of proportion. How do you kn

Ratling [72]

Answer:

If two ratios are equivalent to each other, then they are said to be in proportion. For example, the ratios 1:2, 2:4, and 3:6 are equivalent ratios.

Step-by-step explanation:

Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

A box contains cards number 1-10. A card is drawn at random, then replaced, and a second card is drawn. What is the probability

aliina [53]

You would solve this by determining how many numbers from 1-10 can be multiples of 5. That's obviously 5 and 10. So that's 2/10 or reduced to 1/5. Now the second question you have to find how many numbers from 1-10 are prime. Prime is a number that can only be divided by 1 and itself. So that would leave you with 1, 3, 5, 7. I think where the trick comes into play is if you drew a 5 or 10 the first time, then you didn't place those cards back in the box, you couldn't draw them again. So the answer would 4/10 or 2/5 if you could draw the 5 again. Or I supposed if you had drew the 10 the first time and not the 5. I assume however, they want you to exclude 5 and 10 because it was part of the first section of this equation. So that would mean only 1, 3, and 7 or 3/10.

Find the perimeter of the rectangle whose: length = 1m, breadth = 75cm

Arte-miy333 [17]

Length of the rectangle = 1 m
Breadth of the rectangle = 75 cm = 0.75 m
We know, perimeter of a rectangle = 2(length + breadth)
Therefore, perimeter of the rectangle
= 2(1 + 0.75) m = 2(1.75) m = 3.5 m

Answer:

The perimeter of the rectangle is 3.5 m or 350 cm.

Hope you could get an idea from here.
