The correct answer is: [C]: " 491 ft³ " .
_______________________________________________
Explanation:
_______________________________________________
Note the formula/equation for the volume of a pyramid:

Volume of a pyramid, "V" :

V = (⅓) *(base area) *
(perpendicular height; that is height measured from center of base to apex) ;
_______________________________________________________
base area (which is a square, in this case) =
length * width = 8 ft * 8 ft = 64 ft ² ;
_______________________________________________________
perpendicular height = 23 ft ;
_______________________________________________________

V = (⅓) * (64 ft ²) * (23 ft) ;

= [(64 ft ²) *(23 ft)] / 3 = 1472 ft³ / 3 ;

= 490. 66666... ft³ ; (that is; "490 ⅔ ft³ ") ; which is closest to (rounds up to):

Answer choice: [C]: 491 ft³ .

Answer:

1. x = 5 2. y = 4 3. x = -2

Step-by-step explanation:

2x - y = 9 -5x + 2y = 13 3x + 4y = -6

<u>4x + y = 21</u> <u>5x + y = -1 </u> <u> 7x(-1) + 4y(-1) = -14(-1)</u> <(multiply all by -1)

Ron has a bag containing 3 green pears and 4 red pears. He randomly selects a pear then randomly selects another pear, without r

denpristay [2]

The third tree diagram is correct.

The probabilities for the first draw are 3/7 for green and 4/7 for red.

If you draw a green pear first, then your probabilities for the second pear would be 2/6 for green and 4/6 for red (since it is done without replacement, the number of pears to choose from changes).

If you draw a red pear first, then your probabilities for the second pear would be 3/6 for green and 3/6 for red.

2sin(2x) + 1 = 3sin(2x) Solve for x with exact answers. The domain is 0 ≤ x ≤ π

Temka [501]

Answer:

x = π/4.

Step-by-step explanation:

3sin(2x) = 2sin(2x) + 1

3sin(2x) - 2sin(2x) = 1

1sin(2x) = 1

sin(2x) = 1

When a variable n = π/2, sin(π/2) = 1 [refer to the unit circle].

2x = π/2

x = π/4.

Hope this helps!

Which of the following correctly compares the uses of bar graphs versus pie charts? bar graphs show patterns in data with variab

saw5 [17]

Answer:

<h3><em>Bar graphs show data involved in distinct categories that do not overlap; whereas, pie charts show data as parts out of a whole (such as out of 100%).</em></h3>

Step-by-step explanation:

A bar graph, also called a bar chart, is used to present categorical variables, which involves rectangular bars with a correlation between a specific category and the frequency of them, this graphs can be also called histograms. It's used in statistics to describe a bunch a data, separating them in categories. This charts can be horizontal or vertical, and an important characteristics is that it's applied to represent discrete categories, that is, values expressed with whole numbers. (An example is attached).

On the other hand, pie charts, or circular charts, are used to indicate proportions from a whole part, like a pie or cake, you have a whole and 100% data and you divided into slices. For example, from the whole population in the U.S. we could divide it by ethnicity, parts from a whole, like show the image attached.

<h3>Therefore, based on each definition, the correct answer is:</h3>

<em>Bar graphs show data involved in distinct categories that do not overlap; whereas, pie charts show data as parts out of a whole (such as out of 100%).</em>
