The exponent is a positive number, so you move the decimal point, that many places to the right:
3.276 x 10^9 = 3,276,000,000
Forgive me if this is wrong. I haven't done stat in a year, but comment if you need clarification!
Answer:
Terry initially had £390
Step-by-step explanation:
The ratio of the original amount is 3:7
Let the original amount Terry has be t and the original amount Faye has be f
3/7 = t/f
or simply 3f = 7t ••••••(i)
Terry putting 220 means he now has
t + 220
Faye withdrew 300
He now has f-300
These values are equal
t + 220 = f-300
f = t+220+300
f = t + 520 ••••••(ii)
Put ii into i
3(t + 520) = 7t
3t + 1560 = 7t
7t-3t = 1560
4t = 1560
t = 1560/4
t = 390
<span>t's call P the number of art brushes that Monique has.
Chelsea has 11xP (that is 11 times as many as Monique)
Together they have:
P + 11xP = 12xP
That means 12xP = 60 (60 is the number of art brushes they have together)
In order to find how much is P, we need to divide:
60 Ă· 12 = 5 brushes
P = 5 ; that means has Monique 5 art brushes.
Chelsea has 11 times as many art brushes as Monique:
11 x 5 = 55 brushes</span>
