Answer:

Let's find the base area:

21 x 9 = 189

Now let's multiply the base area by the height:

189 x 5 = 945

Now let's divide by 3( x 1/3 ):

945 divided by 3(x 1/3) = 315 yd^3 is your answer

Step-by-step explanation:

Formula area of a rectangular Pyramid(just like any other pyramid):

BH x 1/3

To find base we multiply length by width just using the basic formula of finding area of a rectangle.

Then we multiply our base area by our height.

One we've done that we now divide by 3(multiplying by 1/3)

Answer:

315 yd cubed

Step-by-step explanation:

To find the volume of the pyramid, we first need to consult the equation below. Thebase is for the rectangular portion, then after multiplied by the height it is divided by 3 to get the pyramid.

\frac{1}{3} (B * H )

To get the base, we multiply the length by the width.

21 * 9 = 189

189 * 5 = 945

945 divided by 3 = 315

Say you are at a grocery store and find an item without a listed unit price. How would you calculate the unit price for this ite
Aneli [31]

Answer:

Unitary Method

Step-by-step explanation:

If the item is not listed with the unit price we can use different methods to calculate its unit price.

Unit price tells us the cost of each pound, ounce or gram, square foot or meter, etc., of the product.

We can use Unitary Method to calculate the price of each unit. The unitary method is a technique which is used for solving a problem by calculating the value of a single unit, i.e. 1 unit (by dividing) and then finding the necessary value by multiplying the single unit value.

For an instance if a bag of 6 pounds of potato says $7.00, to figure out the price of each pound (that is 1 unit) of potato we can use unitary method:

6 pounds costs $7.00

1 pound costs: \frac{7}{6}=1.17 dollars.

And that is how we calculate the price of each unit.

zloy xaker [14]

The probability that a person could not give up cell phone but could give up television can be expressed as the probability of No could give up cell phone and Yes could give up television, P(NnY) = 0.39

<u>From the two way probability table given</u> :

  • Let, probability that a person could not give up cell phone = N

  • Probability that a person could give up television = Y

The intersection of Y and N = P(Y n N)

  • The probability value at the intersection point using the table given ls 0.39

Therefore, the probability of YnN is 0.39

Ted tossed a coin several times and recorded the number of heads and tails in the following table:
sineoko [7]
<h2>Answer:</h2>

Option: D is the correct answer.

                     D.  0.45

<h2>Step-by-step explanation:</h2>

The results of the experiment are given as follows:

Coin Experiment Side of Coin Number of Tosses

                              Heads                           18

                               Tails                             22

This means that total 40 experiments were performed.

( Since 18+22=40)

Also, the number of times head turn up=18

Hence, the experimental probability of getting heads is:

Ratio of number of times head turn up to the total number of experiments performed.

Hence,

Probability=\dfrac{18}{40}\\\\\\Probability=0.45

   Hence, the experimental probability of getting head is:

                                         0.45
