X × 75% = £45
x = £45 / 75%
x = £45 / 0,75
x = £60
Answer:
a(4) = 15/4
Step-by-step explanation:
The general formula for a geometric series with common ratio r and first term a(1) is
a(n) = a(1)*r^(n - 1)
and so, if a(1) = 30 and r = 1/2, we have
a(n) = 30*(1/2)^(n - 1)
and the fourth term is then:
a(4) = 30*(1/2)^(4 - 1) = 30/8 = 15/4
Answer:
37.7 = h
Step-by-step explanation:
Area of a rectangle is base * height
A =bh
Substitute what you know
1059.37 = 28.1 * h
Divide each side by 28.1
1059.37/28.1 = 28.1 * h/28.1
37.7 = h
