Answer:
[tex](x - 9)^{2} [/tex]
Answer:
81
Step-by-step explanation:
Move −18x, so
x^2+c−18x
To find the c value
c =(b/2)^2
divide the coefficient of x by 2 and square the result.
Divide 18 by 2
(-1⋅9)^2
Multiply −1 by 9
(−9)^2
Raise −9 to the power of 2 and get your answer
=81

Elian and Alberto won tickets at a arcade. When they put their tickets together they had exactly 100. Alberto won 10 tickets less then Elian. Let A be the number of tickets Alberto won and e be the number of tickets Elian won.
Answer: See explanation
Step-by-step explanation:
Number of tickets Elian won = e
Number of tickets Alberto won = A = e - 10
Therefore, Elian + Alberto ticket = 100
e + (e - 10) = 100
2e - 10 = 100
2e = 100 + 10
2e = 110.
e = 110/2
e = 55
Elina has 55 tickets
Alberto has 55-10 = 45 tickets

A student wrote a list of six consecutive integers. If the sum of the first integer and sixth integer is 1, which integer is the least of the six integers?
A. -2
B. 1
C. 3
D. 5
Answer:
A
Step-by-step explanation:
The student wrote a list of six consecutive integers.
The sum of the first integer and the sixth is 1.
Let the first integer be represented by n.
Then the subsequent integer will be (n + 1).
Therefore, our sequence is:
n, n + 1, n + 2, n + 3, n + 4, and n + 5.
The sum of the first and sixth is 1. Therefore:
[tex](n)+(n+5)=1[/tex]
Solve for n. Combine like terms:
[tex]2n+5=1[/tex]
Thus:
[tex]2n=-4[/tex]
And:
[tex]n=-2[/tex]
Thus, our first term is -2.
Therefore, our sequence is:
-2, -1, 0, 1, 2, 3
The least of the six integers is -2.
Our answer is A.
Answer:
A

a) a train leaves westchester at 6.30. What time should it arrive at middlewich? b) Kate lives in Northton. She works in southam and starts works at 9am. What is the time of the latest train that she can catch to get to work on time? C) how long does the train take to travel from the westchester to east wick?
Answer:
a). 6:51
b). 6:30 am
c). 34 minutes
Step-by-step explanation:
a). Train leaves Westchester at 6:30.
From the arrival - departure table in column (2),
Arrival time of the train at middlewich = 6:51
b). Kate has to reach Southam before 9:00 am
Therefore, time of the latest train that she can catch to get to work on time is 6:30 am
By this train she can reach at 07:19 at Southam.
c). Duration of journey from Westchester to Eastwick = 06:34 - 06:00
= 00:34
≈ 34 minutes

You invest $4000 into an account that compounds interest on a quarterly basis at 3%. how much money will you have after 5 years? Compound interest formula: A = P(1+r/n)^(nt)

Step-by-step explanation:
So sorry if this is wrong i tried
The amount after 5 years is $4,644.74.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P[tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $4000
n = 4
r = 3%
t = 5 years
A = 4000 [tex](1 + 0.03/4)^{20}[/tex]
A = 4000 x [tex]1.0075^{20}[/tex]
A = $4,644.74
Thus,
The amount after 5 years is $4,644.74.

a customer left a tip of 25$ this is 20% of his bill. whats the price of the bill?
Answer:
i think 150
Step-by-step explanation:
Answer: $30.00
Step-by-step explanation:
First, convert the 20% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.
0.20 x $25.00=$5.00.
$25.00 + $5.00 = $30.00.
