The last Harry Potter novel has just arrived and by 11 am a line has formed outside the crowded bookstore. Knowing you have class at noon, you ask the guard at the door how long you can expect to wait. She tells you that she is permitted to let 6 people into the store only after 6 people have left; customers are leaving at the rate of 2 customers per minute; and she has just let 6 new customers in. Also each customer spends an average of 15 minutes browsing at books and 10 minutes waiting in line to check out.
How many minutes are there between groups of customers entering the book store?

Kelvin rolls a dice twice. The first number he gets is 4. The sum of the two numbers is smaller than 8. Which number CANNOT be the second number?
Answer:
5, 6
Step-by-step explanation:
When Kelvin rolls the dice twice, he can't get more than a 4 because if he did, the sum of the two numbers would be more than a 8. So, the numbers that cannot be the second number is 5 and 6.

In ΔRST, \text{m}\angle R = (11x+3)^{\circ}m∠R=(11x+3) ∘ , \text{m}\angle S = (x+15)^{\circ}m∠S=(x+15) ∘ , and \text{m}\angle T = (2x+8)^{\circ}m∠T=(2x+8) ∘ . Find \text{m}\angle R.M∠R.
Answer:
<R = 124°
Step-by-step explanation:
Note that the sum of angles in a triangle is 180degrees. In a triangle RST
Given
∠R=(11x+3)°
∠S=(x+15)°
∠T=(2x+8)°
Required
∠R
First we need to get the value of x;
since <R+<S+<T = 180
11x+3+x+15+2x+8 = 180
11x+x+2x+3+15+8 = 180
14x+26 = 180
14x = 180-26
14x = 154
x = 154/14
x = 11°
get <R
Since <R = 11x+3
<R = 11(11)+3
<R = 121+3
<R = 124°
Hence the measure of <R is 124°

A fruit jucie company includes 1.231 ounce of apple jucie in 6.65- ounces bottel of a mixied fruit jucie. How much of the bottel of mixied fruit jucie is NOT apple jucie? THANK YOU!
Answer: 81.49% of bottle of mixed fruit juice is NOT apple juice.
Step-by-step explanation:
Quantity of mixed fruit juice = 6.65 ounces
Quantity of apple juice in it = 1.231 ounce
Quantity of mixed fruit juice is NOT apple juice = (6.65-1.231) ounces
= 5.419 ounces
Fraction of bottle is not apple juice = [tex]\dfrac{5.419}{6.65}\approx0.8149=81.49\%[/tex]
Hence, 81.49% of bottle of mixed fruit juice is NOT apple juice.

Triangle A″B″C″ is formed using the translation (x + 2, y + 0) and the dilation by a scale factor of one half from the origin. Which equation explains the relationship between segment AB and segment A double prime B double prime? coordinate plane with triangle ABC at A negative 3 comma 3, B 1 comma negative 3, and C negative 3 comma negative 3 segment A double prime B double prime = segment AB over 2 segment AB = segment A double prime B double prime over 2 segment AB over segment A double prime B double prime = one half segment A double prime B double prime over segment AB = 2
Answer:
A. segment A double prime B double prime = segment AB over 2Step-by-step explanation:
Triangle ABC with coordinates of:
A = (-3, 3), B = (1, -3), C = (-3, -3)Translation (x + 2, y + 0), coordinates will be:
A' = (-1, 3), B = ( 3, -3), C = (-1, -3)Dilation by a scale factor of 1/2 from the origin, coordinates will be:
A'' = (-0.5, 1.5), B'' = (1.5, -1.5), C= (-0.5, -1.5)Let's find the length of AB and A''B'' using distance formula
d = √(x2-x1)² + (y2 - y1)²AB = √(1-(-3))² + (-3 -3)² = √4²+6² = √16+36 = √52 = 2√13A''B'' = √(1.5 - (-0.5)) + (-1.5 - 1.5)² = √2²+3² = √13We see that
AB = 2A''B''Now the answer options:
A. segment A double prime B double prime = segment AB over 2
CorrectB. segment AB = segment A double prime B double prime over 2
Incorrect. Should be AB = A''B''*2C. segment AB over segment A double prime B double prime = one half

4 ice cream cones cost $6. At this rate, how much do 7 ice cream cones cost?
this is a test for middle schoolers but anyone is free to answer
Answer:
$42
Step-by-step explanation:
Equation: y = 6x
x = number of ice cream cones
y = 6(7) = 42
Hi! I believe your answer is $10.50. If it's $6 for 4 ice cream cones, divide 6 by 4 and you'll get 1.5, or $1.50 per ice cream cone. For 7 ice cream cones, multiply the unit rate ($1.50 per ice cream cone) by 7. The total cost is $10.50. I hope this helps you! Good luck and have a great day. ❤️✨

x^4 + 3x^2 - 18 = 0
PLEASE SHOW WORK.
Step-by-step explanation:
Here is your explanation:
((x4) - 3x2) - 18 = 0 Factoring x4-3x2-18
The first term is, x4 its coefficient is 1 .
The middle term is, -3x2 its coefficient is -3 .
The last term, "the constant", is -18
Step-1 : Multiply the coefficient of the first term by the constant 1 • -18 = -18
Step-2 : Find two factors of -18 whose sum equals the coefficient of the middle term, which is -3 .
-18 + 1 = -17 -9 + 2 = -7 -6 + 3 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -6 and 3
x4 - 6x2 + 3x2 - 18
Step-4 : Add up the first 2 terms, pulling out like factors :
x2 • (x2-6)
Add up the last 2 terms, pulling out common factors :
3 • (x2-6)
Step-5 : Add up the four terms of step 4 :
(x2+3) • (x2-6)
Which is the desired factorization

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 1 and the Trailing Constant is 3.
The factor(s) are:
of the Leading Coefficient : 1
of the Trailing Constant : 1 ,3

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 6 is not a square !!(x2 + 3) • (x2 - 6) = 0 product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.Solve : x2+3 = 0
Subtract 3 from both sides of the equation :
x2 = -3
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ -3
In Math, i is called the imaginary unit. It satisfies i2 =-1. Both i and -i are the square roots of -1
Accordingly, √ -3 =
√ -1• 3 =
√ -1 •√ 3 =
i • √ 3
The equation has no real solutions. It has 2 imaginary, or complex solutions.
x= 0.0000 + 1.7321 i
x= 0.0000 - 1.7321 i
Solve : x2-6 = 0
Add 6 to both sides of the equation :
x2 = 6
When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:
x = ± √ 6
The equation has two real solutions
These solutions are x = ± √6 = ± 2.4495
Solving x4-3x2-18 = 0 directly
Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula
Solve x4-3x2-18 = 0
This equation is reducible to quadratic. What this means is that using a new variable, we can rewrite this equation as a quadratic equation Using w , such that w = x2 transforms the equation into :
w2-3w-18 = 0
Solving this new equation using the quadratic formula we get two real solutions :
6.0000 or -3.0000
Now that we know the value(s) of w , we can calculate x since x is √ w
Doing just this we discover that the solutions of
x4-3x2-18 = 0
are either :
x =√ 6.000 = 2.44949 or :
x =√ 6.000 = -2.44949 or :
x =√-3.000 = 0.0 + 1.73205 i or :
x =√-3.000 = 0.0 - 1.73205 i
so we found four answers:
x = ± √6 = ± 2.4495
x= 0.0000 - 1.7321 i
x= 0.0000 + 1.7321 i

Write the equation of the line fully simplified slope-intercept form.
Answer:
The equation of the line is y = -x + 8
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineFrom the given figure
∵ The line passes through points (8, 0) and (0, 8)
∴ x1 = 8 and y1 = 0
∴ x2 = 0 and y2 = 8
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{8-0}{0-8}=\frac{8}{-8}=-1[/tex]
∴ m = -1
→ Substitute it in the form of the equation above
∵ y = -1(x) + b
∴ y = -x + b
∵ b is value y at x = 0
∵ At x = 0, y = 8
∴ b = 8
→ Substitute it in the equation above
∴ y = -x + 8
∴ The equation of the line is y = -x + 8
