Answer:

G ( I think)

Step-by-step explanation:

It's a reflection of it's self, so the only reasonable answer would be the the letter of the copied image of itself.

Think about it like a mirror. One side is what you see, but what is facing it is the original, so if the original is C then its copy is G.

Answer:

A =112.1 in ^2

Step-by-step explanation:

The area is base times height

A =bh

A = 11.8 * 9.5

A =112.1 in ^2

Answer:

87% would be faster than 58 seconds

Step-by-step explanation:

Landon runs the 400 meter dash, his finishing times are normally distributed with a mean of 60 seconds and a standard deviation of 1 second

[tex]\mu = 60[/tex]

Standard deviation =[tex]\sigma = 1[/tex]

We are supposed to find Landon were to 38 practice trials of the 400 meter dash , how many of those trials would be faster than 58 seconds , to the nearest whole number i.eP(x<58)

[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{58-60}{1}\\Z=-2[/tex]

Refer the z table for p value

P(x<58)=0.0228

Landon were to 38 practice trials

So, P(x<58)=[tex]38 \times 0.0228=0.8664[/tex]

So, 86.64%  would be faster than 58 seconds

Hence 87% would be faster than 58 seconds

Answer:

18

Step-by-step explanation:

you do PEMDAS

there is parenthesis

12-6+6 times 2

there is multiplication

12-6+12

then there is subtraction and addition so you have to do it left to right

18

Answer:

18

Step-by-step explanation:

When solving these types of questions, you want to remember PEMDAS. According to PEMDAS, P is parenthesis. (14-8) is in parenthesis. 14-8 is 6.

Now the equation looks like this:

12-6 + (6)2

There are no Exponents in this equation, but there is multiplication. If there are no operations between two integers, that means it is likely to be multiplication. 6 x 2 is 12.

Now the equation looks like this:

12-6+ 12

Even though, according to PEMDAS, Addition is before subtraction, you can do either one from left to right. Even with multplication and division.

Now the equation looks like this:

6+12

Obviously 6+12 is 18. So, 18 is the answer.

Answer:

1005cm³

Step-by-step explanation:

8² x 3.14 = 200.96 = surface area of face

200.96 x 5 = 1004.8 = 1005cm³

Answer:

Volume = 1004.8ft*3

However with full measure π it is slightly higher on calculator.

1005.31ft^3

Step-by-step explanation:

(V):3.14 x 8^2=200.96 x 5

(V):200.96 x 5 = 1004.8

Volume =1004.8ft^3

Answer:

No complex roots; 3 real roots

Step-by-step explanation:

If a third order polynomial has any complex roots, then as a rule it has 1 real root and 2 complex roots.  In this particular case, the polynomial has three real roots, as can be determined by graphing the function.  The graph crosses the x-axis in 3 places.

Answer:

[tex]x = \frac{23}{22} [/tex]

Step-by-step explanation:

[tex]22x = 23 \\ \frac{22x}{22} = \frac{23}{22} \\ x = \frac{23}{22} [/tex]

Answer:

x = 23/22 = 1.045

Step-by-step explanation:

Solving a Single Variable Equation :

1.1      Solve  :    22x-23 = 0

Add  23  to both sides of the equation :

                     22x = 23

Divide both sides of the equation by 22:

                    x = 23/22 = 1.045

The number of loads of laundry can Natalie do with her bottle of laundry detergent is A = 4/9

A line plot is a graph that shows data as points or check marks above a number line, indicating the frequency of each value.

If we need to compare two different groups , a line chart does have one advantage for visualizing frequency distributions

It displays information as a series of data points called 'markers' connected by straight line segments

Given data ,

A shelf has different sizes of bottles of laundry detergent. This line plot shows the number of cups of laundry detergent in each bottle.

Natalie buys the kind of laundry detergent that has 4 bottles.

She uses 18 cup for each load of laundry she does.

From the line plot , we can see that

4 cups = 8 volume

So , A = 8/18

Hence , the number of loads = 8 / 18

Total fruits = 7+ 4 = 11

Probability of apples = 7/ 11

The probability of the apples should be [tex]7\div 11[/tex]

Since A basket contains seven apples and four peaches. You randomly select a piece of fruit and then return it to the basket.

So here the total fruits should be

The literary device known as repetition is used to emphasize the same concept or idea or to communicate a particular message by repeatedly using it.

Although repetition typically relates to sentences or words, it can also be present in the sounds that words make. There are three different techniques to show repeat with noise. Consonance, harmony, starting, and alliteration are the names of these three literary devices.

The term "as usual" is repeated in this situation to emphasize how nothing exceptional was going on; it was just the block bash as usual. The predictability demonstrates that everyone's attitudes and behaviors were uniform and fairly predictable. That is wanted to predict the neighborhood and how they act in a certain way

Step-by-step explanation:

Remember that the sum of any 2 sides of a triangle always must be greater than the length of the third side.

A. 9 + 5 = 14  so NO

B. 8 + 5 = 13 which is less than 14 so NO

C. 5 + 5 = 10 which is less than 14 so NO

D. 12 + 5 = 16 which is greater than 14.

12 + 5 > 14

14 + 12 > 5

5 + 14 > 12

Answer: 40 units

Step-by-step explanation:

(7,3) (12,3) on the same y coordinate, 5 squares apart

(12,3) (12,11) on the same x coordinate, 8 squares apart

8 × 5 = 40

The area of a rectangle with vertices at (7,3), (12,3), (12, 11), and (7,11) is 40 square unit.

A brace of figures called equals are used to detect a point or a form in a two- dimensional aeroplane . Thex-coordinate and the y- match are two figures that define a point's position on a 2D aeroplane .

We have vertices of rectangle as

vertices at (7,3), (12,3), (12, 11), and (7, 11).

Now, the coordinates (7,3) and (12,3) have the same y coordinate  also the difference in x match is 5 places piecemeal.

and, (12,3) and (12,11) have the same x coordinate then the difference in y coordinate is 8 squares apart.

So, the Area of rectangle

= 8 × 5

= 40 square unit
