Select all ratios equivalent to 1:3 A. 9:21 B. 5:15 C. 4:12

Answers

Answer 1
all of the answers would be correct/ equivalent to 1:3
Answer 2
It’s B, and C because 1 x 9 is 9 and 9 x 3 is 27 which proves its incorrect.

And 1 x 5 is 5 and 3 x 5 is 15 so its correct.

Lastly, 1 x 4 is 4 and 3 x 4 is 12 so that proves that this is correct.




Hope this helps! :)

Answer: if I’m wrong I think it’s 56

Step-by-step explanation: it’s an educational guess

Answer: (F) 56 large stickers.

Out of 96 stickers, divide that by the sum of the 7 and 5 in the ratio: 96 / 12 = 8.

Multiply 7 * 8 = 56.
5 * 8 = 40, and 56 + 40 = 96.

Answers

Answer:

840cm²

Step-by-step explanation:

The two small triangle areas:

b × h / 2 = 12 × 5 = 60 / 2 = 30cm²

So two triangles would be 60cm²

Now, for the top rectangle:

b × h = 26 × 12 = 312cm²

The middle rectangle:

b × h = 26 × 13 = 338cm²

And the bottom last triangle:

b × h = 26 × 5 = 130cm².

Now to add them all: 60 + 312 + 338 + 130 = 840cm²

I advice you to just check to make sure the calculations were right! Good luck with the rest of your finals :)

It would be 840
