Let x = Initial Price

If we increase x by 5%, we are adding 0.05x

Therefore, the new price = x + 0.05x = 1.05x

If the ticket has increased by £2.30, £2.30 is 5% of the initial price, or 0.05x

0.05x = 2.30

x = 2.30/0.05

x = 46

Therefore, the price of the ticket before the increase was £46

You can also check this backwards by doing 46*0.05 = 2.30

What fraction is equivalent to 20 in simplest fraction form
SIZIF [17.4K]

Answer:

I believe its 20% or 20/100 or 1/5

Step-by-step explanation:

i mean, 20% is 20/100 or 1/5. the number already a fraction. the denominator is out of 100.

20% = 20/100

then you change it to simpliest form.

20 / 20 = 1

100 / 20 = 5 = 1/5

Hellllllllllllllllllllllllllllp!!!!!!!!!!!!!!!! will give brainliest
zavuch27 [327]

Answer:

Step-by-step explanation:

3in/4 = 0.75in(Diameter) for each circle

r = 0.375

A = πr^2

A(for 1 circle) = 0.141π

A(for 1/4 circle) = 0.035π

A x 4 because we have 4 circles =

0.141π

0.141π(area of middle) + 0.141π(area of circle) =

0.282π or 0.886in^2
