Lucia would need 54 green beads and 36 purple beads.

  • Total length of her beaded string = 21.6 centimeters
  • Decided length for green beads = 0.4 centimeters
  • Decided length for purple beads = 0.6 centimeters
<h2>Further Explanation</h2>

To determine the amount of green and purple beads she would use for the whole beaded string, the total length of her beaded string (21.6) would be divided by the amount of colored beads (For green: 0.4; For purple: 0.6) she decided to use for the beaded string separately.

Therefore, 21.6 ÷ 0.4; and 21.6 ÷ 0.6

Hence,  

<h3><u>For green beads:</u></h3>

Total length of her beaded string ÷ Decided length for green beads

= 21.6 ÷ 0.4 ( can be expressed as \frac{216}{4})

= \frac{216}{4}

= 54

<h3><u>For purple beads:</u></h3>

Total length of her beaded string ÷ Decided length for purple beads

= 21.6 ÷ 0.6 (can be expressed as \frac{216}{6})

= \frac{216}{6}

= 36

Therefore she would need 54 green beads and 36 purple beads for her beaded string.  

The above expression is a number problem, and was solved with the aid of division. Division is a basic arithmetic operation which deals with splitting or dividing two or more numerical values into different equal part.

It is also a function of BODMAS (which is an order of operations). BODMAS basically means Bracket, Orders, Division, Multiplication, Addition, Subtraction.

21.6 ÷ 0.4 = 54 times for green
21.6 ÷ 0.6 = 36 times for purple

Together, 90 beads. Separately, 54 green and 36 purple.

Which graph shows the solution to the inequality Negative 3 x minus 7 less-than 20
Aleksandr-060686 [28]

Answer:

A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.

Step-by-step explanation:

we have

-3x-7

Solve for x

Adds 7 both sides

-3x

-3x

Divide by -3 both sides

Remember that

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

so

x> 27/(-3)\\x>-9

The solution is the interval (-9,∞)

therefore

A number line goes from negative 10 to positive 10. An open circle appears at negative 9. The number line is shaded from negative 9 through positive 10.

Jenny is eight years older then twice her cousin sues age. The sum of their ages is less then 32. What is the greatest age that
maw [93]

Answer:

The age of Sue could be 7 years

Step-by-step explanation:

Jenny is 8 years older than twice her cousin Sue's age.

The first equation will be :

J = 8 + 2S ---------(1)

The sum of their ages is less than 32.

The second equation will be :

J + S < 32  ----------------(2)

Now rearrange both equations :

8 + 2S + S < 32

3S < 32 - 8

3S < 24

S < 24/3

S < 8

S = 7

The age of Sue could be 7 years.
