Step-by-step explanation:
A bakery sells, on average, 100 special breads per day and collects with these sales, on average, R $ 300.00. It was found that the quantity of special breads sold daily increases if the price is reduced, according to the equation q = 400 - 100p, in which q represents the quantity of special breads sold daily and p, its price in reais. In order to increase the flow of customers, the bakery manager decided to run a promotion. To do so, it will modify the price of special bread so that the quantity to be sold daily is as large as possible, without decreasing the average daily collection on the sale of this product. The price p, in reais, of the special bread in this promotion should be in the range
a) R $ 0.50 p
b) R $ 1.50 p
c) R $ 2.50 p
d) R $ 3.50 p
e) R $ 4.50 p
If the price is p and the quantity of bread sold is q = 400 - 100p, the average collection, in reais, depending on the price p, is given by R (p) = (400 - 100p). P
For this collection to be R $ 300.00, you must have:
(400 - 100p). p = 300 ⇔ 4p - p² = 3 ⇔ p² - 4p + 3 = 0 ⇔ p = 1 or p = 3
R $ 300.00
The current price is R $ 3.00, as R $ 300,000 / 100 = R $ 3
To maintain the collection, the price must be lowered to R $ 1.00 (R $ 0.50 <R $ 1.00 <R $ 1.50)

Please help it’s urgent!!!!!
Answer:
5 hours; Home Decor
Step-by-step explanation:
First thing you want to do is make an equation of the two to find when they'll be the same price. So it'll look something like this:
500+35x=600+15x
Get like terms together
100=20x
divide
x=5
After 5 hours, they'll be the same price.
For the second half, plug in the number 3 instead of 5 into the original equation
500+105 600+45
605 645
So he'd go with the first company

Question 16
which statement BEST describes the relationship between Georgia and Great Britain during the colonial period?
A Farm machinery was shipped from Georgin, manufactured goods were shipped from Britain, and neither side controlled what was produced
Manufactured goods were shipped from Georgia, raw materials were shipped from Britain, and Georgia controlled which raw materials were produced
Food crops were shipped from Georgia, manufactured goods were shipped from Britain, and Georgia controlled which manufactured goods were produced
D
Raw materials were shipped from Georgia, manufactured goods were shipped from Britain, and Britain controlted which raw materials wore produced
Answer: D . Raw materials were shipped from Georgia, manufactured goods were shipped from Britain, and Britain controlled which raw materials wore produced
Step-by-step explanation:
In the colonial era of the United States, the British who were in charge then engaged in an Economic policy called Mercantilism. This was a system where they limited imports into Britain but encouraged exports from Britain so that they would maintain a favorable balance of trade.
A key part of this system was having colonies that goods could be exported to and that raw materials could be acquired from at a cheap rate.
Southern colonies like Georgia fulfilled this mandate more than the rest as they would ship raw materials to Britain and buy manufactured goods from them with Britain controlling which raw materials Georgians produced.

John's sister is twice his age. In 5 years the sum of their ages will be 31. How old are John and his sister now? Briefly explain how you arrived at your answer.
Like usual, we can solve this question using an equation. Let’s assume that John’s age is x, and his sister’s age is y.
x = 2y
To figure out John’s age, we need to know his sister’s age. He’s 2 times older than his sister.
x + y = 27
The sum of their ages is 27, and we can substitute the value of x here to figure out y.
2y + y = 27
We can now simplify this, and get y by itself.
3y = 27
Now, we can divide by 3 to get the y by itself.
y = 9
We now know that John’s sister is 9.
Now, using our original equation, we can substitute in the value of y.
x = 2(9)
We can simplify this.
x = 18
John’s age is 18!
Hope this helps.

The partial blueprint for an office building shows one outer wall and a perpendicular inner wall. Which of the following could be the equation of the inner wall, if the outer wall is represented by the equation y = 2/5x-1
a. y= -5/2x -4
b. y= -2/5x-4
c. y=5/2x-4
d. y=2/5x-4
Answer:
a. y= -5/2x -4
Step-by-step explanation:
An equation that is perpendicular to another equation must have the opposite slope. In other words, the perpendicular equation will be the opposite sign & the reciprocal of the equation it is perpendicular to. In this case, the perpendicular slope is -5/2x. Therefore, the only answer possible is a.

Matek spends 4/5 of his homework time on math. He spends 1/12 of it on writing. What fraction of his homework time is spent on math or writing? Simplify the answer if possible.
Answer:
53/60 of his homework time
Step-by-step explanation:
We need to find 1/12 of 4/5, which can be calculated via the addition:
1/12 plus 4/5
1/12 + 4/5 = 5/60 + 48/60 = 53/60
So Matek spent 53/60 of his homework time on writing or math
Jane wants to buy carpet for her room measuring 400 square feet. She purchased carpet that costs $20 per square yard. How much will it cost to have her room carpeted? (1 square yard = 9 square feet) Explain how you solved it.
Answer:
About $888.88
Step-by-step explanation:
divide 400 by 9 to get the total number of how much square yards she needs
400/9 = 44.44444444
Multiply 44.44444444 with $20 to get the amount which is about 888.88
If three times a number is at least four or more than eight times the number, which of the following is true? A-The number is at least negative four-fifths.
B- the number is at most four-fifths.
C-The number is at least four-fifths.
D-The number is at most negative four-fifths .
Answer:
I believe A...
Step-by-step explanation:
Sorry if i'm wrong):
Option (A) The number is at least negative four-fifths. is correct because x is at least -4/5.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
If three times a number is at least four or more than eight times the number,
Let x be the number
Mathematically, it can be written as:
3x is at least 4 + 8x
3x - 8x is at least 4
- 5x is at least 4
x is at least -4/5
Thus, option (A) The number is at least negative four-fifths. is correct because x is at least -4/5.

The standard deviation from the National Health and Nutrition Survey is 1.29 hours. What is the variance (rounded to the hundredth place) ?
Answer:
variance = 1.66 hours
Step-by-step explanation:
It is given that,
The standard deviation from the National Health and Nutrition Survey is 1.29 hours.
We need to find the variance. We know that the relationship between the variance and the standard deviation is given by :
[tex]\text{Variance }=\text{standard deviation}^2\\\\\text{Putting all the values, we get :}\\\\\text{Variance }=(1.29)^2\\\\\text{Variance }=1.664\ \text{hours}[/tex]
or
Variance = 1.66
So, the variance is 1.66 hours.
Solve the rational equation 4 divided by x equals quantity 3 times x plus 2 end quantity divided by x squared, and check for extraneous solutions.
Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
[tex]\frac{4}{x}=\frac{3x+2}{x^2}[/tex]
Step 2: Solve for x
Cross multiply: [tex]4x^2=x(3x+2)[/tex]Distribute x: [tex]4x^2=3x^2+2x[/tex]Subtract 3x² on both sides: [tex]x^2=2x[/tex]Subtract 2x on both sides: [tex]x^2-2x=0[/tex]Factor: [tex]x(x-2)=0[/tex]Solve: [tex]x = 0, 2[/tex]Step 3: Check
Plug in x to verify it's a solution.
Substitute: [tex]\frac{4}{0}=\frac{3(0)+2}{0^2}[/tex]Evaluate: undef (cannot divide by 0)Substitute: [tex]\frac{4}{2}=\frac{3(2)+2}{2^2}[/tex]Evaluate: [tex]2=\frac{6+2}{4}[/tex]Evaluate: [tex]2=\frac{8}{4}[/tex]Evaluate: [tex]2=2[/tex]Mrs. Balcon owes the dentist $342.
