Answer:

108 : 1

Step-by-step explanation:

1 foot = 12 inches

81 foot = 81 * 12 = 972 inches

Scale factor = 81 feet  : 9 inches

                    = 972 : 9

                    = 972 ÷ 9  : 9÷9

                    = 108 : 1

What is the answer to the equation 5+2(x-1)=12
S_A_V [24]
5+2(x-1)=12 \\ \\ 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \\ \\ 2(x - 1) = 7 \ / \ simplify \\ \\ x - 1 =  \frac{7}{2} \ / \ divide \ each \ side \ by \ 2 \\ \\ x =  \frac{7}{2}  + 1 \ / \ add \ 1 \ to \ each \ side \\ \\ x =  \frac{9}{2} \ / \ simplify \\ \\

So, the answer to this problem is x = 9/2 or x = 4.5.

Brian invests £1850 into his bank account. He receives 2.7% per year simple interest. How much will Brian have after 3 years? Gi
Rama09 [41]

Answer:

£1999.85

Step-by-step explanation:

A = P(1 + rt)

Where:

A = Amount after t years

P = Initial amount invested = £1850

r = Interest rate = 2.7%

t = Time in years = 3 years

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.7%/100 = 0.027 per year.

Solving our equation:

A = £1850(1 + (0.027 × 3))

A = £1999.85

Therefore, Brian will have £1999.85 after 3 years.
