400 - 35 - 65 = 300
100 seats being used, so 300 seats left unused
(Btw, do you happen to know of a certain Northeast Middle School at all?)

Answer:
f(0) is approximately equal to 7.07
Step-by-step explanation:
All you need to do here is substitute a zero wherever you see an x in the equation, giving us:
[tex]f(0) = 2(0)^2 + 5\sqrt{0 + 2}\\f(0) = 5\sqrt{2} \\f(0) \approx 5 \times 1.414\\f(0) \approx 7.07[/tex]

Which of these is a simplified form of the equation 9y + 5 = 7 + 3y + 2y? (1 point)
9y = 7
14y = 12
5y = 12
4y = 2
Answer:
4y = 2
Step-by-step explanation:
9y + 5 = 7 + 3y + 2y
9y-2y-3y=7-5
4y=2
Answer:
4y=2 is your answer
Step-by-step explanation:
9y + 5 = 7 + 3y + 2y
9y+5=7+5y
maintaining common form in each side
9y-5y=7-5
4y=2
Jack’s BBQ has a policy of adding a 16% tip if u have a party of 8 or more. Write an equation to represent the relationship between tip(t) and the bill(b). Then determine how much the tip would be if the bill is $145. (I need it as fast as possible, WILL GIVE BRAINLIST)
Answer:
B x 0.16 = T
If the bill is $ 145, the tip will be $ 23.2.
Step-by-step explanation:
Since Jack’s BBQ has a policy of adding a 16% tip if there is a party of 8 or more, to write an equation to represent the relationship between tip (t) and the bill (b), the following reasoning must be performed:
B x 0.16 = T
B is the value of the bill after consumption.
In turn, to determine how much the tip would be if the bill is $ 145, the following calculation must be performed:
145 x 0.16 = T
23.2 = T
Thus, if the bill is $ 145, the tip will be $ 23.2.

Bismuth-210 has a half-life of 5 days. Find
the amount of Bismuth-210 left from a
100-gram sample after 5 weeks?
Answer:
0.78125g
Step-by-step explanation:
Since there are 35 days in 5 weeks, 7 half-lives of Bismuth-210 will take place. To solve for that, you can divide 100g by 2, 7 times or simply: [tex]\frac{100}{2^{7}}[/tex]
[tex]\frac{100}{2} =50\\\frac{50}{2} =25\\\frac{25}{2} =12.5\\\frac{12.5}{2} =6.25\\\frac{6.25}{2} =3.125\\\frac{3.125}{2} =1.5625\\\frac{1.5625}{2} =0.78125[/tex]

Evaluate when
a =3 b= 4.5 and h = 6
Answer:
For Example: Evaluate a2b for a = –2, b = 3, c = –4, and d = 4.
Step-by-step explanation:
To find my answer, I just plug in the given values, being careful to use parentheses, particularly around the "minus" signs. Especially when I'm just starting out, drawing the parentheses first may be helpful:
a2 b
( )2 ( )
(–2)2 (3)
(4)(3)
12
Note how using parentheses helped me keep track of the "minus" sign on the value of a. This was important, because I might otherwise have squared only the 2, ending up with –4, which would have been wrong.
By the way, it turned out that we didn't need the values for the variables c and d. When you're given a big set of expressions to evaluate, you should expect that there will often be one or another of the variables that won't be included in any particular exercise in the set.
Evaluate a – cd for a = –2, b = 3, c = –4, and d = 4.
In this exercise, they've given me extra information. There is no b in the expression they want me to evaluate, so I can ignore this value in my working:
(–2) – (–4)(4)
–2 – (–16)
–2 + 16
16 – 2
14

a dealer made a profit of 25% by selling a car for a 1000 naira find the cost price of the car
Given:
A dealer made a profit of 25% by selling a car for a 1000 naira.
To find:
The cost price of the car.
Solution:
Let x be the cost price of the car.
A dealer made a profit of 25% by selling a car. So, the selling price of the car is
[tex]S.P.=x+\dfrac{25}{100}x[/tex]
[tex]S.P.=x+0.25x[/tex]
[tex]S.P.=1.25x[/tex]
It is given that the selling price of the car is 1000. So,
[tex]1.25x=1000[/tex]
[tex]x=\dfrac{1000}{1.25}[/tex]
[tex]x=800[/tex]
Therefore, the cost price of the car is 800.

i really need help i don't get it
Answer:
The correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.
Step-by-step explanation:
By Hierarchy Rules of Operators, we must follow these steps:
(i) Subtract 6 from 14.
[tex]\frac{1}{2}\times 8\times 6 + 4[/tex]
(ii) Multiply the result in (i) by [tex]\frac{1}{2}[/tex] and 6.
[tex]24+4[/tex]
(ii) Add 4 to the result in (ii).
[tex]28[/tex]
Hence, the correct answer is: Find half the difference of 14 and 6, multiply by 6, then add 4.
