Answer:
200cm^2
Step-by-step explanation:
When we need to find length of a rectangle we need to divide area by breadth.
Length of a rectangle = Area ÷ breadth.
ℓ = A ÷ b.
Similarly, when we need to find breadth of a rectangle we need to divide area by length.
Breadth of a rectangle = Area ÷ length.
I am gonna say like a 76 percent hope this helps p.s. nice macbook
Answer:
Colin gets 
of the total money
Step-by-step explanation:
If we let the total amount be "90" (or any multiple of 9), then the solution gets much easy.
Let total money be 90.
Caroline gets 1/9, so that is:
1/9 * 90 = 10
Remaining is 90 - 10 = 80
This 80 is divided in the ratio 1:3, that means Colin gets 1 part and Sarah gets 3 part. That is 1 + 3 = 4 parts altogether.
80 divided in 4 parts is 80/4 = 20 each part.
Colin gets 1 part, that is 1 * 20 = 20
Colin gets 20 OUT OF 90 (total initial).
<em>What proportion is that? We simply divide and reduce!!</em>
<em />
20/90 = 2/9
Colin gets of the total money
Answer:
No
Step-by-step explanation:
Lets find out the ratios for the bracelet and the necklace. Remember that a ratio between a and b if the relation between the amounts of a respect to the amount of b and can be written as a:b or a/b.
So, the bracelet has 14 red and 19 gold, so the ratio between red and gold is 14/19. We cannot simplify this ratio as there are not common factors between 14 and 19, because 19 is a prime number.
Now lets find out the ratio for the necklace. As there are 84 red and 133 gold the ratio will be 84/133. For this ratio to be equal to 14/19 it should be that 84 is multiple of 14 and 133 multiple of 19, and both multiples must the same, this is:
84/133 = 14/19
or
84/14 = 133/19
And we know that 84/14 = 42/7 = 6
And 133/19 = 7
So, both ratios are not equal. If we verify on a calculator we have:
14/19 = 0.743
84/133 = 0.63
Thus, we can confirm they do not have the same ratio of red to gold beads.
Multiply by 12. The answer is 105in.
