Help!!! A business can manufacture 50 unicycles a week and sell all of them for $200 each. The owner is considering increasing the price of the unicycles, but she knows that it will decrease sales. She uses this equation to estimate how much in dollars, y, she will make if she raises the price by x dollars:
y=10,000+50x−x^2
If she wants to make $10,6000, what is the least amount she can raise the price of each unicycle?
=====================================================
Explanation:
I'm assuming you meant to write $10,600 instead of $10,6000.
We'll replace y with this value and solve for x.
[tex]y=10,000+50x-x^2\\\\10,600=10,000+50x-x^2\\\\0=10,000+50x-x^2-10,600\\\\-x^2+50x-600 = 0[/tex]
Use the quadratic formula with a = -1, b = 50, c = -600
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-50\pm\sqrt{(50)^2-4(-1)(-600)}}{2(-1)}\\\\x = \frac{-50\pm\sqrt{100}}{-2}\\\\x = \frac{-50\pm10}{-2}\\\\x = \frac{-50+10}{-2} \ \text{ or } \ x = \frac{-50-10}{-2}\\\\x = \frac{-40}{-2} \ \text{ or } \ x = \frac{-60}{-2}\\\\x = 20 \ \text{ or } \ x = 30\\\\[/tex]
We go for the smaller x value because the question asks "what is the least amount she can raise the price?".
If she raises the price by $20, then she would estimate to make about $10,600.
Six gallons of water splashed out of the wading pool when Santa jumped in. Five gallons splashed out when Mrs. Claus jumped in beside Santa. What number should be added to the original amount in the pool to find how many gallons are left?
Answer:
x + (-11)
Step-by-step explanation:
so you lost the 6 gallons and 5 gallons. so to find the original amount (I will use x). you need to subtract it from the amount. but since you are being asked to add. you use a negative
x + (-6) + - (5)
or you can combine
x + (-11)
it is equivalent to
x - 11
A prism with a base area of 3 m² and a height of 4 m is dilated by a factor of 32. What is the volume of the dilated prism? Enter your answer, as a decimal, in the box. M³.
The volume of the dilated prism when the dimensions are dilated by a factor of 32 is 393,216 m³.
What is dilation?Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.
Given
A prism with a base area of 3 m² and a height of 4 m is dilated by a factor of 32.
The area after the dilation.
Dilated area = (Dilation)² x base area
Dilated area = 32² x 3
Dilated area = 3072 m²
The height after the dilation.
Dilated area = Dilation x base area
Dilated area = 32 x 4
Dilated area = 128 m
The volume of the dilated prism.
Volume = 3072 x 128
Volume = 393216 m³
The volume of the dilated prism is 393,216 m³.

An armchair was purchased for a cost price of $380 and marked up to a retail price. It was then
discounted by 10% to a sale price of $427.50 . What is the percentage mark-up from the cost price

Step-by-step explanation:
i hope this helped
The required percentage markup from the cost price to the retail price is 1.25%.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
An armchair was then discounted by 10% to a sale price of $427.50.
Cost of armchair then = 427.50 - 10% × 427.50
The cost of the armchair then = $384.75.
Now, the cost of the armchair is given $380.
Percentage mark up is given as = 387.75 - 380 / 380 × 100% = 1.25%
Thus, the required percentage markup from the cost price to the retail price is 1.25%.

Choose the compound inequality that can be used to solve the original inequality |3x – 5| > 10. –10 < |3x – 5| < 10 3x – 5 > –10 or 3x – 5 < 10 3x – 5 < –10 or 3x – 5 > 10 –10 < 3x – 5 < 10.
The compound inequality solving original inequality |3x – 5| > 10 is given by: Option C: [tex]3x - 5 < -10[/tex] or [tex]3x -5 > 10[/tex]
What is magnitude and sign?A number has both magnitude(its absolute value) and its sign(positive or negative).
If numbers are negative, the more their magnitude increases, the lesser they become.
If numbers are positive, the more their magnitude increases, the greater they become.
Thus, for -5, the magnitude is 5, and sign is –ve.
Also, positive numbers > 0 > negative numbers.
|x| = magnitude of x.
Thus, |3x-5| > 10 is true if (3x-5) < -10 (since in that case, 3x-5 is negative but in negative signed values, values with more magnitude are smaller. Thus |3x-5| > |-10} = 10)
or (3x-5) > 10
(in case if (3x-5) is non-negative).
Thus, the compound inequality solving original inequality |3x – 5| > 10 is given by: Option C: [tex]3x - 5 < -10[/tex] or [tex]3x -5 > 10[/tex]

Answer:
Step-by-step explanation:
We simplify 16x - 12 - 24x + 4 as -8x - 8
1. 4+16x - 12(1+2x)
Break the bracket out, we get : 4+16x-12+24x
Simplify : -8 + 40x, not equivalent to -8x - 8.
2. 40x - 16
Divide this by 5, we get : 8x - 3.2 = -8x + 3.2 (not equivalent also.)
3. 16x - 24x - 4 + 12
Simplify : -8x + 8 (also not equivalent)
4. -8x-8
It's literally the same as the simplified form of the expression.
So, only the fourth expression is equivalent to the original one.

The linear function that best represents the relationship between the foot lengths of the elephants and their shoulder height is given as follows:
y = 5.71x - 5.65.
How to obtain the linear function?The slope-intercept definition of a linear function is presented as follows:
y = mx + b.
In which the coefficients of the function are defined as follows:
m is the slope, representing the rate of change of the output y relative to the input x.b is the y-intercept, representing the numeric value of y when x = 0.From the image given at the end of the answer, two points of the line are given as follows:
(15, 80) and (50, 280).
Given two points, the slope is obtained as the change in y divided by the change in x, hence:
m = (280 - 80)/(50 - 15) = 5.71.
Hence:
y = 5.71x + b.
When x = 15, y = 80, hence the intercept b is obtained as follows:
80 = 5.71(15) + b
b = 80 - 5.71(15)
b = -5.65.
Hence the equation is given as follows:
y = 5.71x - 5.65.
