Answer:
<em><u>17: 480</u></em>
(We first arrange all of the candidates except b in a line. This can be done in 5! ways. We now add b to the line. Since we now want to count the arrangements where b is positioned next to a, there are two possibilities for the position of b. (Either left of a or right of a).
There are thus 2⋅5! ways of arranging the candidates so that a and b are next to each other, and hence 6!−2⋅5!=4⋅5!=480 ways of arranging the candidates so that a and b are not next to each other)
<u><em>18</em><em>:</em></u><em><u> </u></em>i don't know sorry
Total surface area of the present=
=2*(5 in * 4.5 in)+2*(5 in * 3.5 in) + 2*(4.5 in * 3.5 in)=
=45 in² + 35 in² + 31.5 in²=111.5 in²
answer:the total surface area of the present is 111.5 in²
The correct answer would be B, or the second option.
In a function like this, the y-intercept, or the term without a variable, can be always be interpreted as a sort of starting amount, or a base amount.
Because we're given 5x + 20, we know 20 will be the base, or starting value, while 5 is the amount being added per value of x, which is equal to weeks.
Thus, the correct answer is B.
Answer:
£70.00
Step-by-step explanation:
You basically want to find what she spent in total, then subtract the amount she spent on ingredients.
50 glasses of lemonade at £2.10 each would be £105. (50*2.1)
Subtract the cost of ingredients, which is £35, with the total she made, £105, to get £70 (105-35)
