Answers
The equation of the time she can afford to park her car is 2 + 3t = N
How to determine the time she can afford to park her carThe given parameters are
Entrance charge = $2.00Rate per hour = $3.00Assume she stays for t number of hours, the total charges would be
Total = Entrance charge + Rate per hour * Number of hours
This gives
Total = Entrance charge + Rate per hour * t
Substitute the known values in the above equation
So, we have
Total = 2 + 3t
From the question, she has N dollars
So, we have
2 + 3t = N
Hence, the expression of the description is 2 + 3t = N

SA = 2lw + 2lh + 2hw
Where;
SA is the surface areal is the length of the cuboidw is the width of the cuboidh is the height of the cuboidNow, let's substitute the values into the formula, we have;
Surface area = 2(5× 2) + 2(5 ×6) + 2(6 × 2)

Surface area = 2(10) + 2(30) +2 (12)
Surface area = 104 in²

the expression becomes

Answers
A.
The initial weight of the goldfish is 0.5 ounces.
Then, for each inch it grows, its weight increases by 0.15 ounces.
So, using the variable r to represent the number of inches it grew, we can write the following equation to determine the value of x for a weight of 1.1 ounces:
[tex]0.5+0.15r=1.1[/tex]B.
Solving the equation for r, we have:

Answers
If the car uses 3 1/8 gallons per hour and the number of hours is 4 2/3, we can multiply both values to find the total amount of gallons used in this time.
First, we need to convert 3 1/8 and 4 2/3 into improper fractions:
[tex]\begin{gathered} 4\text{ }\frac{2}{3}=4+\frac{2}{3}=\frac{12}{3}+\frac{2}{3}=\frac{14}{3}\\ \\ 3\text{ }\frac{1}{8}=3+\frac{1}{8}=\frac{24}{8}+\frac{1}{8}=\frac{25}{8} \end{gathered}[/tex]Now, multiplying the values, we have:
[tex]\frac{25}{8}\cdot\frac{14}{3}=\frac{350}{24}=14.58[/tex]So the car will use 14.58 gallons.

Answers
The non-real solutions are (2 + i√26)/3 and (2 - i√26)/3
How to determine the non-real solutions?The equation of the polynomial expression is given as:
3x^3 + 14x^2 - 14x + 60 = 0
From the question, we have
x = -6
This gives
So, we have
x + 6 = 0
The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0
This is represented as
3x^3 + 14x^2 - 14x + 60/x + 6
Using a graphing calculator, we have
3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10
Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula
So, we have
x = (-b ± √(b² - 4ac))/2a
This gives
x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3
So, we have
x = (4 ± √-104)/6
This gives
x = (4 ± 2√-26)/6
Divide
x = (2 ± √-26)/3
Rewrite as
x = (2 ± i√26)/3
Split
x = (2 + i√26)/3 and x = (2 - i√26)/3
Hence, the non-real solutions of the polynomial expression are x = (2 + i√26)/3 and x = (2 - i√26)/3

Let the numbers be x and x+1.
x2 + (x+1)2 = 313
2x2 + 2x + 1 = 313
2x2 + 2x - 312 = 0
x2 + x - 156 = 0
x2 + 13x - 12x - 156 = 0
x(x + 13) - 12(x + 13) = 0
(x - 12) (x + 13) = 0

Which is greater? -7/10 or -0.66?
Answers
Answer:
-7/10
Step-by-step explanation:
First, we obviously need to convert 0.66 into a fraction. Since -7/10 cannot be changed, we need to change AND simplify -0.66.
-0.66 is equal to -66/100, but we can still simplify this. We can divide the numerator and denominator by 2.
66 divided by 2 is 33.
100 divided by 2 is 50.
-33/50 CANNOT be simplified anymore.
So -7/10 _ -33/50. Which is greater?
-7/10 is closer to 0 on the number line. -33/50 isnt.
So -7/10 is the answer.
-7/10 > -0.66

In how many ways can the digits in the number 9666111 be arranged?
Answers
========================================================
Explanation:
The unique digits are: 9, 6, 1
9 shows up once6 shows up three times1 shoes up three timesThere are 1+3+3 = 7 digits with the repeats mentioned. If we could somehow tell the 6's apart and the 1's apart, then we'd have 7! = 7*6*5*4*3*2*1 = 5040 different permutations.
But because we can't tell the 6's apart, nor the 1's apart, this means we have to divide by (3!*3!). Each 3! represents the number of times the 6's show up and same goes for the 1's.
So (5040)/(3!*3!) = 5040/(6*6) = 5040/36 = 140 is the number of ways to rearrange the digits

Answers
No, they will not have the same amount in their account at any point of time.
Given that:-
Money deposited by Rodney at the opening of savings account = $ 75
Money deposited by Rodney each month in the account = $ 40
Money deposited by Morgan at the opening of savings account = $ 50
Money deposited by Morgan each month in the account = $ 40
Let us imagine that they will have equal amount of money in their accounts at a particular point of time.
Let us consider x to be the number of months when they will have same amount of money in their account.
Hence, we can write,
75 + 40x = 50 + 40x
We can see that,
75 - 50 = 40x - 40x

[tex](a+b)^8=^8C_0a^8b^0+^8C_1a^7y^1+^8C_2a^6b^2+^8C_3a^5b^3+^8C_4a^4b^4+...[/tex]So the 5th term will be
[tex]\begin{gathered} 5th\text{ term = }^8C_4a^4b^4 \\ The\text{ general comb}\imaginaryI\text{nat}\imaginaryI\text{on formula }\imaginaryI\text{s = }^nC_r=\frac{n!}{(n-r)!r!} \end{gathered}[/tex]Then we have
[tex]\begin{gathered} 5th\text{ term = }\frac{8!}{(8-4)!4!}a^4b^4 \\ 5th\text{ term = }\frac{8\times7\times6\times5}{4!}a^4b^4 \\ 5th\text{ term = }\frac{8\times7\times6\times5}{4\times3\times2\times1}a^4b^4=2\times7\times5\times a^4b^4=70a^4b^4=70(ab)^4 \end{gathered}[/tex]So the final answer is 70(ab)^4
