(A) No solution
(B) -8
(C) 8
(D) all real numbers
rationalize the denominator
Answer:
The answer is
[tex]\frac{84 - 31 \sqrt{6} }{30} [/tex]Step-by-step explanation:
[tex] \frac{5 \sqrt{3} - 4 \sqrt{2} }{4 \sqrt{3} + 3\sqrt{2} } [/tex]To rationalize the denominator multiply both the numerator and the denominator by
4√3 - 3√2

A theater company is considering raising the price of its tickets. It currently charges $8.50 for each ticket and sells an average of 200 tickets for
each show. The company estimates that for each $0.25 increase in the price of the ticket, the average ticket sales will go down by 5 people,
Which equation could the company solve to find the number of price increases it could make, x, and still have a revenue of $1,700?
OA. -1.25.12 - 7.50 = 0
OB -- 1.25:2 – 7.50 – 1,700 = 0
Ос. -1.252 + 7.50 = 0
OD. -1.25_2 + 7.53 – 1,700 = 0
Answer:
The answer is c.
Step-by-step explanation:
Equation which represents the company solve to find the number of price increases it could make, x, and still have a revenue of $1,700 is equals to [tex]-1.25x^{2} +7.5x=0[/tex].
What is equation?" Equation is defined as the relation between the variables with the sign of equality."
According to the question,
'x' represents the price of the ticket
Given,
Total revenue = $1700
Current charges = $8.50
Number of average tickets sells =200
Estimate in increase in the price of each ticket = $0.25
Average sales goes down by 5 people
From the given information we get the equation,
[tex](200-5x)(8.5+0.25x)=\$1700[/tex]
⇒[tex]1700 -42.5x+50x-1.25x^{2} =1700[/tex]
⇒[tex]-1.25x^{2} +7.5x=0[/tex]
Hence, the equation for the given condition is equals to [tex]-1.25x^{2} +7.5x=0[/tex]

Question 7 (1 point) If square PQRS with vertices P (2, 6), Q (6, 5), R (5, 1) and S (1, 2) is rotated 180 degrees, what are the coordinates of S' ? Blank 1: Blank 2: Blank 3: Blank 4:
Answer:
S'(-1, -2)
Step-by-step explanation:
Coordinates of the vertices of the square PQRS have been given as P(2, 6), Q(6, 5), R(5, 1) and S(1, 2)
Rule to rotate a point by 180° about the origin,
(x, y) → (-x, -y)
By this rule new coordinates of the image will be,
P(2, 6) → P'(-2, -6)
Q(6, 5) → Q'(-6, -5)
R(5, 1) → R'(-5, -1)
S(1, 2) → S'(-1, -2)
Therefore, coordinates of S' will be (-1, -2).
(50 points!) Whats 7x + 5z(x-z) ÷ 9y, when x = 5, z = 8, and y = 23. Whoever Gives me an answer AND REALLY GOOD EXPLANATION FIRST gets a free brainliest!
Answer: First we will substitute the numbers given for the variables.
Then we will use order of operations to simplify.
7x + 5z(x - z) ÷ 9y would be equal to
7(5) + 5(8) * (5 - 8) ÷ 9(23)
Simplify:
35 + 40(-3) ÷ 207
Use order of operations to multiply 40 and -3; the equation now looks like:
35 + (-120) ÷ 207
Use order of operations to divide -120 and 207; the equation now looks like:
35 + (-0.6)
Add 35 and -0.6:
34.4
The solution to this equation is 34.4.
Answer:
34.4
Step-by-step explanation:
7x + 5z(x - z) ÷ 9y
7(5) + 5(8) * (5 - 8) ÷ 9(23)
35 + 40(-3) ÷ 207
35 + (-120) ÷ 207
35 + (-0.6)
Add 35 and -0.6:

decrease 216 by 37 1/2%
Step-by-step explanation:
In this question we need to decrease 216 by [tex]37\dfrac{1}{2}\%[/tex] or 37.5 %.
For this, firstly find 37.5 % of 216.
[tex]37.5\%\ \text{of}\ 216=\dfrac{37.5}{100}\times 216\\\\=81[/tex]
Now subtracting 81 from 216 to find decrease of 216 by 37.5 %.
So,
216-81 = 135
Hence, 135 is the decrease of 216 by 37.5 %.
The percentage decrease of 216 by 37 1/2% be is 135
Given:
Original value = 216
Percentage decrease = 37 ½%
Decrease = 37 ½% of 216
= 75/2 ÷ 100 × 216
= 37.5 / 100 × 216
= 0.375 × 216
= 81
New value = Original value - Decrease
= 216 - 81
= 135
Therefore, the percentage decrease of 216 by 37 1/2% be is 135

After how many months will Paul and Karina have the same number of video games? How many video games will each have?
24 months
168 games
Step-by-step explanation:72 + 4m = 120 + 2m
4m - 2m = 120 - 72
2m = 48
m = 48 : 2
m = 24 months
After how many months will Paul and Karina have the same number of video games ?24 months

What are the coordinates of the point on the directed line segment from (-3, -9) to (4,5)
Answer:
(2, 1 )
Step-by-step explanation:
Using the Section formula
For endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n
Then coordinates of point are
[ [tex]\frac{mx_{2}+nx_{1} }{m+n}[/tex] , [tex]\frac{my_{2}+ny_{1} }{m+n}[/tex] ]
Here m = 5, n = 2, (x₁, y₁ ) = (- 3, - 9), (x₂, y₂ ) = (4, 5), thus partitioned point
= [ [tex]\frac{5(4)+2(-3)}{5+2}[/tex] , [tex]\frac{5(5)+2(-9)}{5+2}[/tex] ]
= [ [tex]\frac{20-6}{7}[/tex] , [tex]\frac{25-18}{7}[/tex] ]

A wheel with a radius of 19 meters is moving forward at 164.95 meters per second. How fast is the wheel rotating in radians per second?
Answer:
8.68 radians per second.
Step-by-step explanation:
The circumference of the wheel is 2 π r
= 38π meters.
So that is 164.95 / 38π of full turns of the wheel.
1 turn of the wheel = 2π radians , so the answer is
(164.95 / 38π) * 2π
= 164.95 / 19
= 8.68 radians per second.

Find the value of b. Then find the angle measures of the pentagon.

(b +45)
(2b - 90)
90°
Sum of angle
measures: 540°
The sum of angles in a shape is the addition of all angles in the shape. The value of b is 90.
From the attached pentagon, we have:
[tex]Sum = 540^o[/tex] -- sum of angles.
This means that:
[tex]Sum = b + \frac 32b + 2b - 90 + 90 + b + 45[/tex]
Collect like terms
[tex]Sum = b + \frac 32b + 2b + b- 90 + 90 + 45[/tex]
Evaluate like terms
[tex]Sum = \frac{11}2b +45[/tex]
Substitute 540 for sum
[tex]\frac{11}2b +45 = 540[/tex]
Collect like terms
[tex]\frac{11}2b =-45 + 540[/tex]
[tex]\frac{11}2b =495[/tex]
Isolate b
[tex]b =495 \times \frac 2{11}[/tex]
[tex]b =\frac {990}{11}[/tex]
[tex]b =90^o[/tex]
Hence, the value of b is 90.

e:f = 2:3 and f:g = 5:4 work our e:g
Answer:
5/6
Step-by-step explanation:
e/f = 2/3
Then
e= 2f/3
f/g = 5/4
Then
g= 4f/5
So
e/g= 2f/3 / 4f/5 = 1/3 * 5/2 = 5/6
Answer:
5/6
Step-by-step explanation:
e/f = 2/3 After that e= 2f/3 f/g = 5/4 So then g= 4f/5 at last
e/g= 2f/3 / 4f/5 = 1/3 x 5/2 = 5/6What is the value of the expression below when w equals

Mrs.Ruiz bought 4 14 pounds of sliced of ham for $17. At that rate, what is the cost of 1 pound of sliced ham
Answer:
Cost of 1 pound if sliced ham = $4
Step-by-step explanation:
Mrs. Ruiz bought 4 1/4 pounds of sliced ham for $17. At that rate, what is the cost of 1 pound of sliced ham?
Total pounds of ham bought= 4 1/4 pounds
Total cost = $17
what is the cost of 1 pound of sliced ham
Cost of 1 pound if sliced ham = Total cost of 4 1/4 sliced ham / 4 1/4
= $17 ÷ 17/4
= 17 × 4/17
= 4
Note:4 1/4 = 17/4
Cost of 1 pound if sliced ham = $4
