Find the area of the figure
V125BC [204]

Answer: 60 ft

Separate into 2 rectangles and add their areas together!

Vertical rectangle area: 10 x 3 = 30 ft

Horizontal rectangle area: 10 x 3 = 30 ft

Area of entire thing: 30 + 30 = 60 ft

I’ll give brainliest
Nimfa-mama [501]

Answer:

Step-by-step explanation:

Remark

Area of an entire circle = pi * r^2

Area of a sector = angle / 360 * pi * r^2

Givens

angle = 140

radius = 8

Solution

Area = (140/360) * 3.14 * 8^2

Area =0.3889 * 3.14 * 64

Area = 78.15

What is the simplified form of the following expression? 2√27+√12-3√3-2√12
LiRa [457]

Answer:

√3

Step-by-step explanation:

The given expression to be simplified is

2 \sqrt{27}+\sqrt{12}-3\sqrt{3}-2 \sqrt{12}

but

2 \sqrt{27}=2\sqrt{9 \times 3}=2 \times \sqrt{9}\times \sqrt{3}=2 \times 3 \times\sqrt{3}=6 \sqrt{3}

\sqrt{12}=\sqrt{4\times3}= \sqrt{4}\times \sqrt{3}=2\sqrt{3}

Since √12=2√3,this implies that,

2\sqrt{12}=2\times2\sqrt{3}=4 \sqrt{3}

Therefore,

2 \sqrt{27}+\sqrt{12}-3\sqrt{3}-2 \sqrt{12}=6\sqrt{3}+2\sqrt{3}-3 \sqrt{3} -4\sqrt{3}

=(6+2-3-4)\sqrt{3}

=\sqrt{3}

The simplified form of ,

2 \sqrt{27}+\sqrt{12}-3\sqrt{3}-2 \sqrt{12} is √3

The largest sea turtle found in the United States had a mass of 860.24 kg. If the gravitational potential energy associated with
Romashka-Z-Leto [24]
2.4080 meters.

Remember that the definition of work is force over distance. And that the gravitational potential energy that the turtle has will exactly match the work performed in lifting it. So have the following variables
Mass = 860.24 kg
Work = 20320.7 J = 20320.7 kg*m^2/s^2
Gravitational acceleration = 9.81 m/s^2
And we wish to get an answer in meters. So we need to multiply and divide the three numbers we have with all their related units and derive an answer with the unit of m. We can cancel out most of the units by dividing the work by the gravitational acceleration, so
20320.7 kg*m^2/s^2 / 9.81 m/s^2 = <span> <span>2071.427 kg*m

Now we can cancel out the kg unit by dividing by the mass of the turtle. So
</span></span><span> 2071.427 kg*m / 860.24 kg = </span><span> <span>2.407964 m

Rounding to 5 significant figures gives 2.4080 meters.
