Solve for −4.2y+2.1>−2.52

Alchen [17]

Answer:

y < 1.1

Step-by-step explanation:

Step 1: Subtract 2.1 from both sides

-4.2y + 2.1 - 2.1 > -2.52 - 2.1

-4.2y > -4.62

Step 2: Divide both sides by -4.2

-4.2y / -4.2 > -4.62 / -4.2

Since you divided by a negative, that flips the sign.

y < 1.1

Answer: y < 1.1

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to the nearest tenth place.

kap26 [50]

Answer: 68.1

Step-by-step explanation:

The area of a semi-circle is 1/2 the area of a full circle. The area of a full circle is pi*r^2. Therefore, the area of a semi-circle is:

$Area=\pi r^2/2$

$Area=\pi (3)^2/2=9\pi /2$

The area of a rectangle is the length multiplied by the width:

$Area=l*w$

$Area=6*9=54$

The net area is the sum of the rectangle and the semi-circle:

$Area=(9\pi /2)+(54)=68.1$
