90^2+120^2=c^2
180+240=c^2
420=c^2
2 radical 105
The hcf is 1 because 37 is a prime number so the only factors are 37 and 1 but 37 doesn’t go into 17 so the answer is 1
Ok, so we know it costs $1.10 to make a pin, so the cost of making all 1000 pins must have been:

We know that 35% of the pins, hence 350 pins, were given to charity (we assume this means donated for free), and so the company sold 650 pins.
60% of these we sold at $3 each;

So 390 pins sold at $3 each comes to

So the company has already made $1170.
The other 40% of the 650 remaining pins (260 pins) were sold at $5 for 2. We assume from the question that they were only sold in pairs and were all sold, so we can essentially figure out that 130 pairs were sold at $5 each;

So the company has sold the pins for $650 + $1170 = $1820
This means that the company has made
$1820 - $1100 = $720 as profit
So the percentage profit earned (profit/cost times 100%) would be

Which to one decimal place is 65.5% profit.
Hope this helped.
Answer:
36 bottles
Step-by-step explanation:
Each spherical bottle will have a volume of ...
V = (4/3)πr³ = (4/3)π(4.57³) = 399.8 . . . . cubic inches
Each box (12-pack?) will have a volume of ...
V = LWH = (15 in)(5 in)(4.4 in) = 330 in³
This is a smaller volume than even one spherical bottle, so 36 bottles will have the larger volume.
