Step-by-step explanation:

The question could not be solved because you did not include the image of the prism.

However, from the options; it can be deduced that the prism is a rectangular prism

To calculate the volume of a rectangular prism, you consider the following parameters:

And the Volume is then calculated by the products of the above parameters.

[tex]Volume = Length * Width * Height[/tex]

Take for instance, the attached image:

[tex]Length = 5[/tex]

[tex]Width = 8[/tex]

[tex]Height = 2[/tex]

[tex]Volume = 5 * 8 * 2\ units^3[/tex]

or

[tex]Volume = 80\ units^3[/tex]

Answer:

3

Step-by-step explanation:

-5 + 8 = 3

keep inverse opposite:

-5 => -5

- => +

-8 => 8

Answer:

(1) = 3

(2) = 7

(3) = -5

(4) = -7

(5) = -12

(6) = -19

(7) = -8

(8) = 5

(9) = 0

(10) = 0

(11) = -6

Second row:

(18) = -13

(19) = -30

(20) = -5

(21) = -46

(22) = 15

(23) = -8

(24) = -15

(25) = 0

(26) = -7

(27) = -56

(28) = -36

Step-by-step explanation:

Take the last number in the fraction ( the denominator ) and make a segment that long. Than, take the first number in the fraction ( the numerator ) and highlight, bolden, color, or do whatever needs to be done to make sure that the numerator's value stand out.

Answer:

Yes there is an outlier and it is 44

Step-by-step explanation:

Outliers are values that seems to be far greater and lower than the rest of the data

From the given data we can see that 44 is much greater than the rest of the data making it an outlier in the data set

The removal or addition of the value when calculating the mean will make a huge difference in the resulting mean of the data. That's why they are called an outlier

Answer:

2, 1, 1/2, 1/4

Step-by-step explanation:

2¹ = 2

2^0 = 1

2^-¹

= 1/2¹

= 1/2

2^-2

= 1/2²

= 1/2*2

= 1/4

Answer:

62.5 degrees

Step-by-step explanation:

180-55= 125

125/2 = 62.5

The value for angle [tex]x[/tex] will be [tex]70^0[/tex] .

Angle is when two rays meet together then the space between them is angle.

We have,

[tex]x=?[/tex]

A triangle with one of its angle equals to [tex]55^0[/tex] and two sides are equal .

So,

"When two sides are equal then the interior angles opposite to these lines are also equal".

So,

According to the above mentioned theorem the angle other than the angle [tex]x[/tex] will be [tex]55^0[/tex] .

Now, Using angle sum property,

[tex]x+55^0+55^0=180^0[/tex]

[tex]x=180^0-110^0[/tex]

[tex]x=70^0[/tex]

So, the value of [tex]x[/tex] is [tex]70^0[/tex] which is find out using the angle sum property.

Hence, we can say that the value for angle [tex]x[/tex] will be [tex]70^0[/tex] .

Answer: $80

Step-by-step explanation:

You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.

Therefore

$60 = 75%

Now we have to find out what amount of money would be equivalent to 100%:

To do this, find out what amount of money would be equivalent to 25% first.

You can do this by dividing both values by 3.

60 / 3 = 20

75 / 3 = 25

So now $20 = 25%

Now find 100% (which is the original amount) multiply each value by 4 :

$80 = 100%

So the school payed $80 for the book.

Answer:

47.5

Step-by-step explanation:

47.5=100%

57=120%

The input value is 47.5 when the output is 57.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

When the output is 120%, the input is 100%.

And the output is 1.2 times the input.

So, we have the output 57.

To find the input number:

Use division process,

The required number = 57 /1.2

The required number = 47.5.

Therefore, the number is 47.5.
