Answer:

<u>Total</u><u> </u><u>number</u><u> </u><u>of</u><u> </u><u>sweets</u><u> </u><u>in</u><u> </u><u>the</u><u> </u><u>bag</u><u> </u><u>is</u><u> </u><u>2</u><u>8</u>

Step-by-step explanation:

let the total number of sweets in the bag be x :

{ \tt{for \: toffees : }} \\  \frac{1}{4}  \: of \: x

therefore fraction of mints = 1 - fraction of toffees :

=  \frac{4}{4}  -  \frac{1}{4}  \\  \\  =  \frac{3}{4}

therefore:

= >  \frac{3}{4}  \: of \: x = 21 \: mints \\  \\    \frac{3}{4}  \times x = 21 \\ 3x = 21 \times 4 \\ x =  \frac{21 \times 4}{3}  \\ x = 28

total sweets number is 28

The salesperson would earn $800 as gross base paycheck

How many hours of did the salesperson achieve?

The salesperson only worked 40 hours of normal time and there is no overtime, which means that the hourly rate remains $10.00 base salary

In other words, in determining the biweekly pay of the salesperson, we would consider the number of hours in a week, the number of weeks payment is made for and the hourly rate

biweekly gross paycheck=number of weeks*hours per week* hourly rate

number of weeks=2

hours per week=40

hourly rate=$10.00

biweekly gross paycheck=2*40*$10.00

biweekly gross paycheck=$800.00

The biweekly gross paycheck of the sales person is $800,option is the most appropriate

If a=bc, b=ca, c=ab find abc
Svetradugi [14.3K]
Fill in (2) in (1):

a=cca => c^2=1 => c=+1 or c=-1

Fill in (3) in (2)

b=aba => a^2=1 => a=+1 or a=-1

same for (1) in (2): b=+1 or b=-1

To satisfy all conditions at the same time, a, b and c all have to be +1 OR any two of them must be negative (e.g., a=b=-1, c=+1).

In all cases, abc=1
