Answer: the profit is $4750
Step-by-step explanation:
A hardware store pays $3500 for 42 lawnmowers. This means that the amount that the hardware store paid for one lawnmower would be
3500/42 = $500/6
Then the store sells the lawnmowers for $99 each. This means that the total revenue that the store got from selling 42 lawnmowers would be
500/6 × 99 = $8250
Profit = Revenue - cost
Therefore, profit that the store makes from the lawnmower sales is
8250 - 3500 = $4750
To cover 5 miles the wheel covers 3771.42 (approx) turns.
Step-by-step explanation:
Given,
In 20 times turns wheel covers 140 feet.
1 mile = 5280 feet
To find the number of times wheels turns to cover 5 miles.
We will apply unitary method.
Now,
5 miles = 5×5280 feet = 26400 feet
140 feet covers in 20 turns
1 feet covers 
turns
26400 feet covers in ×26400 turns
= 3771.42 (approx) turns
Answer:
A
Step-by-step explanation:
I am a little confused with the "all trees $42" answer but if that means she could buy that size for $42 then I believe that is the answer that should be chosen because for question B, 6 per ft. would likely be 48 because 6x8 = 48, and I don't believe half ft would be $3. As for C, 22 plus 24 is 46. (24 would = $6 x 4 additional ft)
Answer:
Option D is correct
Step-by-step explanation:
The original polynomial is:
–2x2 + 2 + 5x3 – 5x
Arranging in decreasing power of x:
Factoring the given polynomial by grouping:
Now, (x^2-1) can be further solved using formula:
(a^2-b^2)=(a-b)(a+b)
Solving:
So, 
represents the factors of 
Hence Option D is correct.
