Find the surface area of this rectangular prism. Be sure to include the correct unit in your answer.

Calculate the area of the room and then subtract the area of the tiled floor.

area of room = 11 3/4 x 5 = 58 3/4

Area of tiled floor = 7 1/2 x 3 1/4 = 24 3/8

area of carpet = 58 3/4 - 24 3/8 = 34 3/8

answer: 34 3/8

Answer:

A, C,D,E,F

Step-by-step explanation:

We can simply solve the equations by just dividing by the coefficient value of x. For example, we would divide both sides of the first equation by 8 to make the equation into x = 2/24 = 1/12

8x=2/3 --> x=1/12
1.5=2x --> x=0.75
5x=2/7 --> x= 2/35
1/4x=5 --> x=20
1/5=2/3x --> 3/5=2x --> x=3/10

Answer:

-1/2

Step-by-step explanation:

Use the two points shown.

slope = rise/run

Start at teh left point.

Go down 2 units. That is a rise of -2.

Now go right 4 units. That is a run of 4.

slope = rise/run = -2/4 = -1/2

Answer:

9625

Step-by-step explanation:

If 385 alcohol swabs were defective, then 385 is 4% of all produced alcohol swabs.

385*25 = 9625

9625 alcohol swabs were produced

The number of alcohol swabs produced in all was 9625.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is equivalent to the quantity of that value between 1 and 100, and it is highly helpful for forecasting. For instance, if you say 678, we must also know the whole number, but if you say 80%, it is obvious.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

Let's say the total of x number of alcohol produced

4 percent were defective so

0.04 × x = 384

x = 9625 hence a total of 9625 alcohol was produced.

Answer:

23040 bats

Step-by-step explanation:

Let N(t) be the number of bats at time

We know that exponential function

[tex]y = ab[/tex]

According to question

[tex]N(t) = ab^{2}[/tex]

Where t (in years)

Substitute t=2 and N(2)=180

[tex]180 = ab^{2}[/tex]

Substitute t=5 and N(5)=1440

[tex]1440 = ab^{5}[/tex]

Equation (1) divided by equation (2)

[tex]\frac{180}{1440} = \frac{ab^{2} }{ab^{5}} = \frac{1}{b\frac{5-2}{}}[/tex]

By using the property

Substitute the values of b in equation (1)

Substitute t=9

Hence, after 9 years the expected bats in the colony=23040 bats

An equation is formed of two equal expressions. The value of x is the equation ax-b=c is (c+b)/(a).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The solution of x in the given equation can be written as,

[tex]ax - b = c\\\\ax = c+b\\\\x = \dfrac{c+b}{a}[/tex]

Hence, the value of x is the equation ax-b=c is (c+b)/(a).

Answer:

  97.2 m³

Step-by-step explanation:

The volume of a triangular prism is half the volume of a rectangular prism with the same length, width, and height.

  V = 1/2LWH

  V = 1/2(9 m)(7.2 m)(3 m) = 97.2 m³

_____

Additional comment

The relation we used above comes from the more general formula for the volume of a prism:

  V = Bh

where B is the area of the base.

You know a rectangular base will have an area of ...

  A = bh

and a triangle with the same base and height will have an area of ...

  A = 1/2bh

That is, the base area of a triangle is half that of a rectangle with the same dimensions. When we use this fact in the volume formula, we find the volume of a triangular prism is 1/2 that of a rectangular prism with the same length, width, and height.

Answer:

[tex]\frac{-3}{-26}[/tex]

Step-by-step explanation:

[tex]\frac{-x-8}{x^{2}-4x-21}[/tex] is what you are looking for.

So with x = -5, it would look like this

[tex]\frac{-(-5)-8}{-5^{2}-(-5)4-21}[/tex]

Simple math now.

-(-5) is 5

[tex]-5^{2} = -25[/tex]

-5 * -4 = 20.

So it should be [tex]\frac{5-8}{-25+20-21}[/tex]

5-8=-3

-25+20-21 = -26

So the answer is[tex]\frac{-3}{-26}[/tex]
