Answer:

216 m³

Step-by-step explanation:

let's calculate the area of the front face and then multiply it by 4m

11*3 + (11-4)*3

(left and right triangle equal a rectangle area here)

= 33 + 21

= 54

multiplied by 4

-> 216

the last step is like multiplying with height in other exercises and other bodies

How many solutions does the equation 5x+17=4(3x−1) have?
Stella [2.4K]

<u>Answer:</u>

one solution = 3

<u>Step-by-step explanation:</u>

Let's solve your equation step-by-step.

5x+17=4(3x−1)

Step 1: Simplify both sides of the equation.

5x+17=4(3x−1)

5x+17=(4)(3x)+(4)(−1)(Distribute)

5x+17=12x+−4

5x+17=12x−4

Step 2: Subtract 12x from both sides.

5x+17−12x=12x−4−12x

−7x+17=−4

Step 3: Subtract 17 from both sides.

−7x+17−17=−4−17

−7x=−21

Step 4: Divide both sides by -7

-7x/-7 = -21/-7 = 3

Adam is an opera singer. Below are the number of times that his voice cracked during each of six concerts
Gre4nikov [31]

In this picture dots are clearly shown the frequency of the concert.

<h3>What is Frequency?</h3><h3>Frequency refers to the number of times an event or a value occurs. A frequency table is a table that lists items and shows the number of times the items occur.</h3>

Here, in given data about the six concerts

Concerts              Frequency

    0                              2

    1                               2

    2                              1

    3                              1

Thus, on number line we mark 2 dots on zero, 2 dots on one, 1 dot on two and 1 dot on 3.

Diana works at a clothing store. she sold 1/5 of the total number of green shirts on Monday and 3/12 of the total number of gree
Doss [256]

Answer:

Step-by-step explanation:

3/12 really is 1/4  (Divide top and bottom by 3) 3/3 = 1 and 12/3 = 4

1/5 + 1/4 = 4/20 + 5/20 = 9/20

There is something we don't know about this question. If you put a remark, I will come back and look at it.

Is there any tricks to memorize the special right triangle's sides?
noname [10]
Sohcahtoa
My algebra teacher got us all to remember that word because...
Soh - Sin = Opposite / Hypotenus
Cah - Cos = Adjacent / Hypotenus
Toa - Tan = Opposite / Adjacent
Sin, Cos, and Tan are what you can use to find missing triangle sides if you know at least one other angle besides the 90 degree angle.

PLZ HELP GEOMETRY BELOW
katen-ka-za [31]

This is known as Einstein's proof, not because he was the first to come up with it, but because he came up with it as a 15 year old boy.

Here the problem is justification step 2.  The written equation

BC ÷ DC = BC ÷ AC

is incorrect, and wouldn't get us our statement 2, which is correct.

For similar triangles we have to carefully pair the corresponding parts to get our ratios right:

ABC ~ BDC means AB:BD = BC:DC = AC:BC so BC/DC=AC/BC.

Justification 2 has the final division upside down.
