Reuben learned in art class that a mosaic is made by arranging small pieces of colored material such as glass or tile to create

anastassius [24]

Pattern is the rule that guides the formation of a set.

The sequence of the first five mosaics is 5, 8, 11, 14, 17
The sequence is arithmetic
There are 32 tiles in the tenth mosaic.

From the given design, the number of tiles used is:

$T_1 = 5$

$T_2 = 8$

$T_3 = 11$

(a) The first five

Notice that the difference in the number of tiles of successive mosaic is 3.

This means that:

$T_4 = T_3 + 3 = 11 +3 = 14$

$T_5 = T_4 + 3 = 14 +3 = 17$

So, the sequence of the first five mosaics is 5, 8, 11, 14, 17

(b) The type of sequence

The sequence is arithmetic

This is so, because the difference in the number of tiles of successive mosaic is 3.

This difference is called the common difference

(c) The number of tiles in the tenth mosaic

The nth term of an arithmetic sequence is:

$T_n = T_1 + (n - 1) \times d$

In this case:

$T_1 = 5$

$d =3$

$n = 10$

So, we have:

$T_{10} = 5 + (10 - 1) \times 3$

$T_{10} = 5 + 9 \times 3$

$T_{10} = 5 + 27$

$T_{10} = 32$

There are 32 tiles in the tenth mosaic.

Tim has L inches of wire. He cuts the wire into pieces. The length of each piece is k inches. How many pieces of wire does Tim h

Yuki888 [10]

Answer:

L/k

Step-by-step explanation:

If Tim has a wire that is L inches long and each piece is k inches long, then you would divide the total length by the length of each individual to get the number of pieces.

So,

L/k

3(5x+2)=2(3x-6) help i need to show work and I have no idea how to do this

tester [92]

Answer: its −2

Step-by-step explanation:

3*(5*x+2)-(2*(3*x-6))=0

Step by step solution :

STEP

Pulling out like terms

2.1 Pull out like factors :

3x - 6 = 3 • (x - 2)

Equation at the end of step

(3 • (5x + 2)) - 6 • (x - 2) = 0

STEP

Equation at the end of step 3

3 • (5x + 2) - 6 • (x - 2) = 0

STEP

Pulling out like terms

5.1 Pull out like factors :

9x + 18 = 9 • (x + 2)

Equation at the end of step

9 • (x + 2) = 0

STEP

Equations which are never true

6.1 Solve : 9 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

6.2 Solve : x+2 = 0

Subtract 2 from both sides of the equation :

x = -2

One solution was found :

x = -2
