Answer=10:40
Explanation:
Don’t know how to type the symbol in font of the 50 so I will substitute
£50=$50
So 1:4
Add it up
1+4=5
So 5 total units
$50=5
Divided by 5
$10=1 units
So 1:4=10:10 times 4=10:40
Range: (-infinity, 4]
the ] signifies that the four is included in the range, rather than ) which means reaching but never approaching. this is why we use ( ) for - and + infinity, cause it can never be reached.
minimum: (-infinity, infinity)
keep it in same format as you have for the maximum
increasing
the interval -infinity
We can set up a proportion, and let x be the amount 16kg would cost: 14/154=16/x. We simplify 14/154 = 1/11. Next, we cross-multiply to get (1)(x)=(16)(11), so x=176. Therefore, 16kg of apples cost $176.
