ELEN [110]

Answer:

A \approx 113.10cm^2

Step-by-step explanation:

The circle is a flat surface or area limited or closed by a circumference. It is a two-dimensional figure and is formed by making a curve where it will always have the same distance to the center. Its area can be calculated using the following formula:

A=\pi r^2\\\\Where:\\\\r=radius

Therefore the area of the circular baking tray is:

A=\pi (6)^2=\pi*36=36 \pi=113.0973355\approx 113.10 cm^2

Hello from MrBillDoesMath!

b = 0.6


Discussion:

The question can be written as

b - 7.4 = -6.8  =>           (now add 7.4 to each side)

b - 7.4 + 7.4 = -6.8 + 7.4 =>       ( note: -7.4 + 7.4 = 0)

b = 0.6

Thank you,

Last year, James earned £1,100 per month. This year, he's had a 4% increase in his monthly pay. He worked 40 hours per week for
avanturin [10]

Answer:

A = £7.15 per hour

James' average pay per hour this year is £7.15 per hour

Step-by-step explanation:

Given;

Last year pay = £1,100 per month

This year, he's had a 4% increase in his monthly pay

This year pay P = 1,100 + 4% of 1,100 = 1,100 +1,100(0.04)

This year pay P = £1,144 per month

Yearly pay Tp= 12 × P = 12 × £1,144 = £13,728

Number of hours worked this year;

He worked 40 hours per week for 48 weeks in the year

N = 40 hours per week × 48 weeks per year

N = 1920 hours per year

Average pay per hour this year A;

A = Yearly pay/Number of hours worked this year

A = Tp/N

A = £13,728/1920hours

A = £7.15 per hour

James' average pay per hour this year is £7.15 per hour
