I don't understand stand this

yanalaym [24]

Step-by-step explanation:

step 1. ABCD is an isosceles trapezoid because AD and BC are parallel, AB and CD are congruent

step 2. x = 56° (definition of an isosceles trapezoid)

step 3. x + y + z + 56 = 360 (definition of a quadrilateral)

step 4. y = z (definition of an isosceles trapezoid)

step 5. 56 + 2y + 56 = 360

step 6. 2y = 248

step 7. y = 124°, z = 124°.

The table below shows the numbers of tickets sold at a movie theater on Friday.

kondor19780726 [428]

Answer:

Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday

= Sum of ( Adult + Children's ) tickets = 1,678 + 976 = 2,654 .... (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold = 2 times the number of adult tickets sold on Friday

= 1,678 x 2 = 3,356

Children's Tickets sold = 3 times the number of children's tickets sold on Friday.

= 976 x 3 = 2, 928

So, the total number of tickets sold on Saturday

= Sum of ( Adult + Children's ) tickets = 3,356 + 2,928 = 6, 284 .... (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 + 6, 284 = 8,938

Hence, total number of tickets sold over these two days is 8,938.

Given a cube with a volume of 27cm3, what is the volume of a square pyramid?

VashaNatasha [74]

First from the information we have, we see that the volume of the cube is 27cm3. So what are the dimensions of its length, width and height? This information will help us to determine the dimensions of the square pyramid.

Volume of a cube is found from the formula V = a3

Where V is volume, and a is the length of one side.

We expand this equation to be:

V= a * a * a

Since all sides of a cube are equal, then this equation will be:

27 = 3 * 3 * 3

Now we know the length width and height of the cube.

Volume of a square pyramid is given by the formula V =1/3ah

Where V is the volume, a is the area of the base of the pyramid, h is the height of the pyramid.

Since it fits perfectly into the cube, then its dimensions are the same as the cube, so:

Area of the base is Length * Width so:

a = 3 * 3 = 9

and height:

h = 3

Now therefore:

V = 1/3 * 9 * 3

V = 1/3 * 27

V = 27/3

V = 9 cm3
