A rectangular prism as 6 sides, 2 of each dimensions.

So this has 2 sides that are 5 x 5

2 sides that are 10 x 5

and 2 sides that are 10 x 5

Find the area of each, multiply by 2 then add them all together:

5 x 5 = 25

10 x 5 = 50

10 x 5 = 50

(25 + 50 + 50) x 2 = 250 m²

First find the area of the triangle.

\sf A=\dfrac{1}{2}bh

\sf A=\dfrac{1}{2}(6)(12)

\sf A=36cm^2

ABCE is a parallelogram, this means that the area of triangle ABE is equal to the area of triangle EBC. The are of the entire trapezoid is 180 square centimeters, we already found the area of the triangle, so that leaves us with:

\sf 180-36=144

So the area of the entire parallelogram must be 144 square centimeters. So each half of the parallelogram must be equal to:

\sf 144\div 2=\boxed{\sf 72cm^2}

Are the events of drawing a rook from the bag of white
Slav-nsk [51]

Answer:

Independent events, 1/16

Step-by-step explanation:

What we must take into account is that they are 2 different bags, because in one bag are the black pieces and in another bag are the white feed, regardless of which piece is removed, one event has nothing to do with the other event being different bags.

Which means that they are independent events.

And the probability for each case would be 1/16, because the probability is one piece out of 16 that is in each bag.

Zach bought a gold necklace originally priced at $50 but on sale for 60% off. After 10% sales tax,
Flura [38]

Answer: $22

Step-by-step explanation:

First we calculate for the sale price.

We have to find how much is 60% of 50.

We do this by:

50 *0.6=\\

This equals 30.

We now subtract the 30 from the 50 to get our sale price.

50 -30 =

The sale price is $20.

Now we have to add a 10% sales tax. This is done by multiply the percentage and adding 1 to it like this.

1+0.1

This equals 1.1

This is what we will multiply the $20 by.

20*1.1=\\

The total cost is $22.

Find the area of the triangle.
NARA [144]

Answer:

16 Unit

Step-by-step explanation:

With P(-2,1) , Q(6,1) , R(4,-3) , S(4,1) ,  the triangle and its altitude look like the one attached in figure.

The length of base PQ is the difference in the x-coordinates of P and Q,

6-(-2)=6+2=8 , because the y-coordinates are both the same as 1.

The height (the length of altitude RS is the difference in the y-coordinates of R and S,

1-(-3)=1+3=4 , because the y-coordinates are both the same as 4 .

The area is

\frac{base*height}{2}=\frac{8*4}{2}=16.
