A salesperson earns a commission of $378 for selling $2100 in merchandise find the commission rate write your answer as a percentag
Answer:
18%
Step-by-step explanation:
Given data
commission = $378
sales =$2100

= 378/2100*100
=0.18*100
= 18%
Hence the percentage commission is 18%
Suppose () = 46%; ( and ) = 10%; and ( or ) = 62% Find (Not ). Can this really be a probability? If not, explain why not.
Answer:
[tex]P(E) = 26 \%[/tex]
Step-by-step explanation:
Given
[tex]P(F) = 46\%[/tex]
[tex]P(E\ and\ F) = 10\%[/tex]
[tex]P(E\ or\ F) = 62\%[/tex]
Required
Find P(E)
In probability:
[tex]P(E\ and\ F) = P(E) + P(F) - p(E\ or\ F)[/tex]
Substitute the right values
[tex]10\% = P(E) + 46\% - 62\%[/tex]
[tex]10\% = P(E) -16 \%[/tex]
Collect Like Terms
[tex]P(E) = 10\% +16 \%[/tex]
[tex]P(E) = 26 \%[/tex]
It is a probability because all probabilities are within the range 0 to 100%

Answer:
b
Step-by-step explanation:
Number is the same as ([tex]4^{-1}[/tex])([tex]2^{3}[/tex] ÷ [tex]4^{-2}[/tex]) is 32.
Option D is correct.
What is PEDMAS rule?PEDMAS is an acronym for the words parenthesis, exponents, division, multiplication, addition, subtraction. The PEDMAS Rule is a set of rules that prioritize the order of calculations.
Given
([tex]4^{-1}[/tex])([tex]2^{3}[/tex] ÷ [tex]4^{-2}[/tex])
= [tex](4^{-1})[/tex] [tex](\frac{2^{3} }{4^{-2} })[/tex]
= [tex](4^{-1})[/tex][tex](\frac{2^{3} }{4^{-1}. 4^{-1}})[/tex]
= [tex](\frac{2^{3} }{4^{-1} })[/tex]
= [tex]2^{3} . 4^{1}[/tex]
= 8 × 4
= 32
Hence, number is the same as ([tex]4^{-1}[/tex])([tex]2^{3}[/tex] ÷ [tex]4^{-2}[/tex]) is 32.
Option D is correct.

Step-by-step explanation:
1. We can tell if the radical is in its simplest form if the square root term is a number that cannot be broken down to give a perfect square factor
what we are saying in this case is that if the number that is under the square root sign is one in which cannot be broken down to give a perfect square or that a perfect square is not its factor. Then it is in the simplest form

HEHE HELP
Answer:
questions mistake look questions and apply the formula 1/2 B×H
if you have a triangle and don't know where are the base and the high use this formula
area = 0.5 × side × side × sin the angle between the 2 sides
area = o.5 (32.4) (49.2) (sin 18.5)
= 797.04 × sin 18.5

Pippa owns a snack bar.
She uses
of a kilogram of spread each day.
Spread costs £3.20 for a 1 kilogram tub and £6.15 for a 2 kilogram tub.
Pippa buys enough spread to last for 14 days.
What is the lowest price Pippa can buy this spread for?
Answer:
£43.05 (I believe, refer to step-by-step explanation.)
Step-by-step explanation:
Let's compare both of these tubs if we were to buy either of them for 14 days.
Starting with the 1 kilogram tub we need to do the calculation:
£3.20 × 14 = £44.80
(Type 3.2×14 into your calculator or write on paper this way to calculate.)
Now let's do the 2 kilogram tub.
£6.15 × 7 = £43.05
(Type 6.15×7 into your calculator or write on paper this way to calculate.)
The reason why I have put 7 instead of 14 is because it is 2 kilograms. Since Pippa uses 1 kilogram per day, you only need to buy 7. 2 × 7 = 14
So comparing either of these prices, buying 7 2-kilogram tubs is much cheaper compared to the 14 1-kilogram tubs.
