Answer:

$Remainder = 3$

Step-by-step explanation:

Given

$1\ |\ 1\ \ 2\ \ -3\ \ 3$

Required

Determine the remainder

Write down the first digit i.e. 1. So, we have:

$1\ |\ 1\ \ 2\ \ -3\ \ 3$

--------------------------------

$|\ 1$

Multiply that 1 by the divisor (1) i.e. $1 * 1 = 1$

Write down the result under the next digit i.e. (under 2)

$1\ |\ 1\ \ 2\ \ -3\ \ 3$

$1$

--------------------------------

$|\ 1$

Sum 2 and 1 i.e $2 + 1 = 3$

$1\ |\ 1\ \ 2\ \ -3\ \ 3$

$1$

--------------------------------

$|\ 1\ \ 3$

Multiply that 3 by the divisor (1) i.e. $1 * 3 = 3$

Write down the result under the next digit i.e. (under -3)

$1\ |\ 1\ \ 2\ \ -3\ \ 3$

$1$ $3$

--------------------------------

$|\ 1\ \ 3$

Sum -3 and 3 i.e $-3 + 3 = 0$

$1\ |\ 1\ \ 2\ \ -3\ \ 3$

$1$ $3$

--------------------------------

$|\ 1\ \ 3\ \ \ 0$

Multiply that 0 by the divisor (1) i.e. $1 * 0 = 0$

Write down the result under the next digit i.e. (under 3)

$1\ |\ 1\ \ 2\ \ -3\ \ 3$

$1$ $3$ $0$

--------------------------------

$|\ 1\ \ 3\ \ \ 0$

Sum 3 and 0 i.e $3 + 0 = 3$

Since there is no other computation to do, the result of the last sum is the remainder.

So:

$Remainder = 3$

Solve for t in d = rt , if d = 57 and r = 30 t = ?

bulgar [2K]

Answer:

1.9

Step-by-step explanation:

First step would be to separate r from t

$\frac{d}{r} = t$

Then just insert the numbers

$\frac{57}{30} = 1.9$

Complete the frequency table:

SOVA2 [1]

The percentage of students age 15 and above travel to school by bus is 47%

<h3>How to complete the table?</h3>

The table of values is given as:

Method of Travel to School

Walk/Bike Bus Car Row totals

Under age 15 18 165

Age 15 and above 65 195

Column totals 152 110 98 360

Using the column total of column 1, we have:

Under age 15 + 65 = 152

This gives

Under age 15 = 87

Using the column total of column 2, we have:

Age 15 and above + 18 = 110

This gives

Age 15 and above = 92

Using the row total of row 1, we have:

Car + 87 + 18 = 165

This gives

Car = 60

Using the row total of row 2, we have:

Car + 65 + 92 = 195

This gives

Car = 38

So, the complete frequency table is

Method of Travel to School

Walk/Bike Bus Car Row totals

Under age 15 87 18 60 165

Age 15 and above 65 92 38 195

Column totals 152 110 98 360

The percentage of students age 15 and above travel to school by bus is:

Percentage = 92/195 * 100%

This gives

Percentage = 47%
