Answer: The correct answer is 44.60

Step-by-step explanation:

Let's find the area of the rectangle first, and then add it with the area of the Circle to find the total area of the whole shape.

We know that the area of a Rectangle is L(Length) x W(Width)

So using the given information, 8 x 4 = 32

So the Area of the Rectangle = 32

Now let's find the area of the given circle,

<em>Area of a Circle: πr2                                     Remember ^ = stands for power</em>

The radius is half of the diameter

The diameter of the circle is 4

4/2 = 2 which is our radius, and now let's replace it in the equation.

= 3.14(r)^2

= 3.14(2)^2

= 3.14(4)

= 12.56 or some may have got 12.57

So now we add all areas together to get the total area,

32+12.57 = 44.57

Now rounding off to the nearest tenths, would give us 44.60

So the area of the figure rounded to the nearest tenth is 44.60

Answer:

44.56

Step-by-step explanation:

Rectangle area:

4 \times 8 = 32

2 circles area (full circle, since they are both a half of circle):

{ (\frac{4}{2}) }^{2}  \times π = 12.56

Total area:

32 + 12.56 = 44.56

Answer:

\angle B=41.81^\circ

Step-by-step explanation:

<u>Trigonometric Ratios</u>

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

\displaystyle \sin \angle B=\frac{2}{3}=0.667

Calculating the inverse sine function:

\angle B=\arcsin (0.667)

\boxed{\angle B=41.81^\circ}

Emerson has an associate degree. Based on the bar chart below, how will his employment opportunities change from 2008-2018?
ANEK [815]

Answer:

19% change

Step-by-step explanation:

Since, Emerson has an associate degree,

His employment is 19% changed in 10 years, i.e. from 2008 to 2018.

Because the bar graph shown the percentage of change in employment from 2008 to 2018.

Also, Employment of associate degree is most affected in 10 years.

And those who have job training and work experience is least affected in these 10 years.

Why is water not used as a solvent in paper chromatography​
Anastaziya [24]

Answer:

Because the kind of compounfds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.

GrogVix [38]
A gets 5 parts and I gets 8 parts
So 5+8=13. A will get 5/13 parts of the total
5/13*32(total)=12.3 since he can’t get .3 we round and Amir gets 12 leaving 20 for Isaac.
