Answer:

Option C 122.1\ cm^{2}

Step-by-step explanation:

we know that

The area of the figure is equal to the area of a rectangle plus the area of semicircle

Step 1

Find the area of the rectangle

The area of the rectangle is equal to

A=bh

we have

b=18\ cm

h=6\ cm

substitute

A=18*6=108\ cm^{2}

Step 2

Find the area of semicircle

The area of semicircle is equal to

A=\frac{1}{2}\pi r^{2}

we have

r=6/2=3\ m

substitute

A=\frac{1}{2}(3.14)(3^{2})=14.1\ cm^{2}

Step 3

Find the area of the figure

108\ cm^{2}+14.1\ cm^{2}=122.1\ cm^{2}

Rectangle = 18 x 6 = 108
Circle:  3.14 x (3)^2 = 3.14 x 9 = 28.26
<span>semicircle: 28.26 / 2 = 14.13
</span>
108 + 14.13 = 122.13

answer
122.13 cm^2

Jonas made the following matrix of temperatures for the first 4 days of January.
valentinak56 [21]

Answer: The correct option is C.

Explanation:

It is given that Jonas made the following matrix of temperatures for the first 4 days of January and for the first 4 days of February.

Let the matrix A and B represents the temperatures for the first 4 days of January and February respectively.

A=\begin{bmatrix}6 & -3 & 3 & -1\end{bmatrix}

B=\begin{bmatrix}1 & -3 & -5 & -6\end{bmatrix}

The difference of January and February is defined by the matrix A-B.

To subtract two matrices, we subtract all the corresponding elements.

A-B=\begin{bmatrix}6-1 & -3+3 & 3+5 & -1+6\end{bmatrix}

A-B=\begin{bmatrix}5 & 0 & 8 & 5\end{bmatrix}

It is the option C.

qaws [65]
So, we write a fraction, which would be 12/100. Then we would do 12/100 = x/550. You could divide 100 by 550, which is 5.5. Then we would multiply 5.5 by 12, which is 66. So 66 people would be wearing glasses.

Answer : 1/2 gallon

Explanation:

There were a total of 5 gallons collected, as the question states.

There are 3 x's above 1/4, 2 x's above 3/8, 4 x's above 5/8 and 1 x above 1. This is a total of

3+2+4+1 = 10 x's. This means there were 10 trees.

If 5 gallons is evenly distributed among 10 trees, this would give us the ratio 5/10, which simplifies to 1/2 gallon per tree.

....this answer is not from me. The same question was asked on brainy and I've copy pated it, it is the right answer tho. Credit goes to "MsEHolt" for answering.
