Answer: 27.89905693 units²

Step-by-step explanation:

First divide the shape into smaller pieces, then find the area of these pieces and then add them up to get the area of the whole shape.

Area of first triangle = 1/2×2×2 = 2

Area of second triangle = 1/2×2×5 = 5

Area of square = 2×2 = 4

Summing up the smaller sides of the shape, we obtain a larger triangle with sides 3.5 and a base of 9. Thus we find the longest/hypotenuse side by applying the Pythagoras Theorem

√((3.5)² + 9²) = √93.25

Area of large triangle = 1/2×3.5×√93.25 = 16.89905693

Add up the areas to find the area of the shape = 16.89905693+5+4+2 = 27.89905693

Nady [450]

Answer:

136+ m ≥ 189 is the required inequality : m: The earning in 4th week

Arthur needs to earn AT LEAST $53 in the fourth week to buy the coat which costs at least $189.

Step-by-step explanation:

The amount earned by Arthur in first 3 weeks = $136

The amount needed to buy a coat = AT LEAST $189

Let us assume the amount Arthur needs to earn more to buy coat = $m

⇒ $ 136 + Amount Earned in 4th week ≥ $189

⇒ 136+ m ≥ 189

The above equation is the NEEDED inequality of the given situation.

Now, solving for the value of m, we get:

136+ m ≥ 189

⇒ m ≥ 189 - 136 = 53

or, m ≥ $53

Hence, Arthur needs to earn AT LEAST $53 in the fourth week to buy the coat which costs at least 189.

Answer:

The yearly payroll will cost the employer $538,250.

Step-by-step explanation:

a) Data and Calculations:

Budgeted payroll = $500,000

Social security tax rate = 6.25%

Medicare tax rate = 1.4%

Social security tax = $31,250 ($500,000 * 6.25%)

Medicare tax amount= $7,000 ($500,000 * 1.4%)

Total taxes amount = $38,250

The total yearly payroll cost should be put at $538,250 ($500,000 + 38,250). This means that as the employees pay taxes amounting to $38,20, the employer will also pay matching taxes amounting to $38,250.
