Answer:

<u>3 cm</u>

Step-by-step explanation:

The formula for the volume of a pyramid is :

  • V = \frac{Ah}{3}

<u>Given</u>

  • Volume = 60 cm³
  • Base Area = 12 cm x 5 cm = 60 cm²

<u>Solving</u>

  • 60 = 60 x h x 1/3
  • 60 = 20h
  • h = 60/20 = <u>3 cm</u>

Find the length of the missing side, given the information below. <br> PLEASE HELP I NEED THIS
Advocard [28]

Answer:

x = 2

UV = 9 ft

VW = 6 ft

WU = 5 ft

Step-by-step explanation:

The perimeter of a figure can be represented as the sum of lengths of all of its sides. In this case we can write:

P = UV + VW + WU

Now, we can substitute the values which we have:

20 = 4x + 1 + 8 - x + 2x + 1

We can combine like terms...

20 = 5x + 10

5x = 10

x = 2

Since UV is represented by 4x + 1, we can substitute in x to find its length.

UV = 4x + 1

UV = 4(2) + 1

UV = 6 + 1

UV = 9

We can do the same for the other two sides:

VW = 8 - x

VW = 8 - 2

VW = 6

WU = 2x + 1

WU = 2(2) + 1

WU = 4 + 1

WU = 5

Whats 4.25 increased by 15%
Firlakuza [10]
You would turn the 15% into a decimal which is .15 then multiply .15 by 4.25. After multiplying those together add 4.25 to the answer.

Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A. Decide in each case whether R
andre [41]

Answer:

Step-by-step explanation:

Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A.

Given that (a,b) R (c,d) if ad=bc

Or (a,b) R (c,d) if determinant

\left[\begin{array}{ccc}a&b\\c&d\end{array}\right] =0

a) Reflexive:

We have (a,b) R (a,b) because ab-ab =0 Hence reflexive

b) Symmetric

(a,b) R (c,d) gives ad-bc =0

Or da-cb =0 or cb-da =0 Hence (c,d) R(a,b). Hence symmetric
