3) Wages of £4.50 per hour are increased by 8%. Find the new hourly wage.

Answer: $\textsf{4.86 per hour}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Initial wage = 4.50, Increase = 8\%}$

Find: $\textsf{New hourly wage}$

Solution: The first step would be to create an expression to incapsulate the scenario and then we would solve for the new hourly wage and we would get our answer.

Create an expression

$\textsf{New = Initial * (1 + Increase)}$

$\textsf{New = 4.50 * (1 + 8\%)}$

$\textsf{New = 4.50 * (1 + 0.08)}$

Simplify the expression

$\textsf{New = 4.50 * (1.08)}$

$\textsf{New = 4.86 hourly wage}$

We were able to determine that the new hourly wage after an increase of 8% would be 4.86 per hour.

Delvig [45]

Answer:

Options A ,B and E

Step-by-step explanation:

Here 2/5 is less then one then all sides are gonna 2/5 of initial length hence reduction occur.

Angles are not gonna affected because it is like zoom in.

Center of dilation can be anywhere as point Q is not specified in question thus it is wrong.

Yeah base of rectangle is reduced by a factor of 2/5.
