larisa86 [58]

Answer:

$56,097

Step-by-step explanation:

First, we have to figure out how much his raise was, so we can convert 3.5% directly to a decimal:

3.5% = 0.035

Then we find

3.5% of 54,200 = 0.035 x 54,200 = 1,897

1,897 + 54,200 = 56,097

So, Mills new salary is $56,097

hope this helps:)

Well in the first one it tells you that 2x is 90.

Help please!!! Find the area of the shaded region. All angles are right angles

kompoz [17]

Answer:

Area = $147 m^{2}$

Step-by-step explanation:

The area of the shaded region is equal to the total area of the full square minus the area of the non shaded region.

The area of a rectangle is its base times its high

So A=b*a.

For the full square, A1= $9m*23m=207m^{2}$

For the non shaded square, A2 = $15m * 4m = 60m^{2}$

So the shaded area is A1-A2 = $207 m^{2} -60 m^{2} = 147 m^{2}$
