Answer:

The answer to your question is 60.7 km

Step-by-step explanation:

This is a ratio and proportion problem, so let's write the proportion.

                                  3  :  26  : :  7  :  x

1.- Convert the expression to a fractional form.

                                  \frac{3}{26} = \frac{7}{x}

2.- Solve the proportion, cross multiplying and back off.

                                 x = \frac{26 x 7}{3}

                                 x = \frac{182}{3}

                                 x = 60.7 km

Vusi makes bead bracelets in different designs. The first design uses 23 beads, the second design uses 29 beads and the third de
sergey [27]

When the remainder theorem is applied to the total number of beads, the number of beads left is 3

<h3>What is remainder theorem?</h3>

The question is an illustration of remainder theorem. Remainder theorem is used to determine the remainder when a number divides another

The number of beads used in each design are given as:

First = 23

Second = 29

Third = 31

Calculate the total number of beads used for all three designs

Total =First + Second + Third

Total =23 + 29 + 31

Total =83

The number of available beads is:

Available = 750

Divide 750 by 83, to get the total number of designs

n = \frac{750}{83}

n =9.03

Remove decimal (do not approximate)

n = 9

The number of beads remaining is calculated using:

Remaining =Available -n \times Total

Remaining =750 -9 \times 83

Remaining =3

Hence, there are 3 beads remaining
