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>

20/90 = 2/9
Colin gets
of the total money
We know that
circumference of a circle=2*pi*r
for r=200 miles
circumference of a circle=2*pi*200-----> 1256 miles
if 360° (full circle) has a length of------------------> 1256 miles
X°----------------> 1000 miles
x=1000*360/1256------> x=286.62°
the answer is
286.62 degrees
12 /4 st your answer would be 3 st
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number
We are given that a(5)=1/16 and r=1/4 so we can say:
1/16=a(1/4)^(5-1)
1/16=a(1/4)^4
1/16=a/256
256/16=a
16=a
So the initial term is 16 so our formula is:
a(n)=16(1/4)^(n-1)
Answer:
c) 2x+1
Step-by-step explanation:
Let's x be number of Nick's goals.
Emma has scored 1 more than twice the number of Nicks.
1 more is +1, of twices the number is 2x.
so 2x+1=15
