An expression not equivalent to 1/343 is 1/342.
Answer:
40n
Step-by-step explanation:
(40+n): The first one is asking to add forty and n, however the question is asking for multiplication so that is not an answer.
(n-40): This one is using subtraction, so this one is an obvious no.
(40/n): This phrase represents division, this could be a possibility because it is the inverse operation, however the numbers need to be reversed.
(40n): Im thinking that you got confused because there was no operation symbol. Whenever a number and a variable are attached without an operation symbol in between, you multiply. So, this is the correct answer.
The weight of the heaviest fish is 15.2 pounds
•since the average is 13.2, we will multiply 13.2 by 5 because there is 5 total fish. this makes a total of 66 pounds between the 5 fish. then we will subtract the weights of the 4 fish given to us from the total of 66, to get the remaining weight of 15.2 pounds. that also happens to be the heaviest weight, so 15.2 is the correct answer
Answer: 300 square feet
Step-by-step explanation:
Let assume x be the sale price
A clothing store advertises that it is having a 25% off sale.
The sale price with 25% discount is f(x) = sale price - 25% of sale price
f(x)= x - 0.25x = 0.75x
For one day only, the store advertises and additional savings of 10%.
The sale price with 10% discount is g(x) = sale price - 10% of sale price
g(x)= x - 0.10x = 0.90x
Use composition function
g(f(x)) = g( 0.75x) = 0.90(0.75x) = 0.675x
That is 0.675/100 = 67.5%
The total percent discount = 100% - 67.5% = 32.5%
what would be the sale price of a $40 sweater?
Here sale price x= 40
So we plug in 40 for x
g(f(40)) = g( 0.75(40)) = 0.90(0.75(40)) = 0.675(40) = 27
The sale price of sweater = $27
