Una pastelería es famosa por dos de sus especialidades de pasteles: el Especial y el Supremo. El Especial requiere para su elaboración medio kilo de azúcar y 8 huevos, teniendo un precio de venta de $200. El Supremo necesita un kilo de azúcar y 8 huevos, teniendo un precio de venta de $270. En el almacén les quedaban 10 kilos de azúcar y 120 huevos.
Given statement solution is :-The ingredients available in the warehouse, a maximum of 15 "Special" cakes and 10 "Supreme" cakes can be made.
To determine how many cakes they can make of each specialty, we need to review the amount of ingredients available in the warehouse and then calculate how many cakes can be made with that amount.
Amount of ingredients in the warehouse:
Sugar: 10 kilos
Eggs: 120
For the "Special" cake:
It requires half a kilo of sugar per cake.
It requires 8 eggs per cake.
Sale price: $200 per cake.
To calculate how many "Special" cakes can be made, we divide the amount of sugar and eggs available in the store by the ingredients required per cake:
"Special" cakes that can be made:
Available sugar / Sugar required per cake = 10 kilos / 0.5 kilos = 20 cakes
Eggs Available / Eggs Required per Cake = 120 Eggs / 8 Eggs = 15 Cakes
Therefore, with the ingredients available in the store, a maximum of 15 "Special" cakes can be made.
For the "Supreme" cake:
It requires a kilo of sugar per cake.
It requires 8 eggs per cake.
Sale price: $270 per cake.
To calculate how many "Supreme" cakes can be made, we again divide the amount of sugar and eggs available in the store by the ingredients required per cake:
"Supreme" cakes that can be made:
Available sugar / Sugar required per cake = 10 kilos / 1 kilo = 10 cakes
Eggs Available / Eggs Required per Cake = 120 Eggs / 8 Eggs = 15 Cakes
Thus, with the ingredients available in the warehouse, a maximum of 10 "Supreme" cakes can be made.
In short, with the ingredients available in the warehouse, a maximum of 15 "Special" cakes and 10 "Supreme" cakes can be made.

5 5/8 feet of purple yarn. How much more
red yarn does Caitlin have than purple
yarn?
Caitlin has 3 3/4 feet more of red yarn than purple yarn.
To find out how much more red yarn Caitlin has compared to purple yarn, we need to subtract the length of the purple yarn from the length of the red yarn.
Given:
Red yarn: 9 3/8 feet

Victoria is paid a salary of $550 a week at her job. She worked 5 hr of overtime during the holidays, and her weekly paycheck came to $690. What is her overtime pay per hour?
Answer:
$28 per hour
Step-by-step explanation:
Let's first find out how much extra Victoria was paid during the week she worked overtime.
Without overtime, Victoria's weekly paycheck would be $550. However, she received $690 that week. The difference between the two amounts is the extra pay for overtime:
Extra pay = Total pay - Regular pay = $690 - $550 = $140
Now, we know that Victoria worked 5 hours of overtime. To find her overtime pay per hour, we can divide the total overtime pay by the number of overtime hours:
Overtime pay per hour = Total overtime pay / Overtime hours = $140 / 5 = $28
Victoria's overtime pay is $28 per hour.
Hope this helps!
Answer:
Victoria is paid $28 per hour of overtime.
Step-by-step explanation:
Get the difference of Victoria's paycheck with and without overtime.
Difference = $690 - $550
Difference = $140
The difference is the amount that she was paid for the overtime.
Since she worked for 5 hours then we can just divide the amount over the time.
Rate = $140/5hours
Rate = $28/hr

Find the lenght and width
Find the admission price for an adult ticket and student ticket.
1) The length of the rectangle is 15 feet and its width is 9 feet.
2) The admission price for an adult ticket is $10 and a student ticket is $6.
How to solve the problems?1) We shall use the formula for the area of a rectangle to find the length and the width:
A = l * w
where:
A = Area.
l = length
w = width.
Given:
l = 6 feet more than the width.
A = 135 feet square meter
First, we write an equation for the area like this:
(w + 6) * w = 135
Expanding the equation:
w² + 6w - 135 = 0
Next, solve the quadratic equation by factoring:
(w - 9)(w + 15) = 0
So either w - 9 = 0 or w + 15 = 0. This means that either w = 9 or w = -15. Since the width cannot be negative, we have w = 9.
Finally, we shall find the length since we know the width. This can be done by using the fact that it is 6 feet more than the width:
l = w + 6 = 9 + 6 = 15
So, the length is 15 feet and the width is 9 feet.
2) We can find the admission price for an adult ticket and a student ticket by using Mathematical operators:
Let,
a = an adult ticket price
s = a student ticket price
From the given information, we get these equations:
5a + 11s = 116
3a + 4s = 54
Next, solve by substitution.
Solving for 'a' in the second equation:
a = (54 - 4s) / 3
Then, substitute the second expression for 'a' into the first equation:
5((54 - 4s) / 3) + 11s = 116
Multiply both sides by 3:
5(54 - 4s) + 33s = 348
Finally, expand and simplify:
270 - 20s + 33s = 348
13s = 78
s = 6
So, a student ticket costs $6.
Plug this value into either equation to get the adult ticket price:
3a + (4 * 6) = 54
3a + 24 = 54
3a = 30
a = 10
So, an adult ticket costs $10.
Therefore,
1) The length of a rectangle is 15 feet and the width is 9 feet
2) The admission price for an adult ticket is $10 and that of a student is $6

Which graph represents the function f(x) = -|x| − 3?
A Reflection over the y-axis and a shift downwards by three units, which is consistent with the function f(x) = -|x| − 3.
The function f(x) = -|x| − 3 can be graphed by following these steps:
To begin, draw a regular x and y-axis and mark it off with an appropriate scale. Then, mark off the negative values on the y-axis and both negative and positive values on the x-axis. After that, we will begin graphing the function f(x) = -|x| − 3, which is a reflection of the absolute value of x over the y-axis and shifted three units down the y-axis. Since the function f(x) = -|x| − 3 is a reflection of the absolute value of x over the y-axis, the graph should be symmetrical. This means that each point to the left of the y-axis is a reflection of the point to the right of the y-axis. Then, we will plot the vertex (0, -3), which is three units down from the origin. Next, we can plot other points using a table of values. We can select values for x that are both negative and positive, such as -2, -1, 0, 1, and 2, and then evaluate them to find the corresponding y values. Then, plot these points on the graph. Finally, we connect the points with a smooth curve, which will form the graph of the function f(x) = -|x| − 3. The graph will be in the shape of a V that opens downwards.Therefore, the correct graph is an option (D). The graph of the option (D) shows a reflection over the y-axis and a shift downwards by three units, which is consistent with the function f(x) = -|x| − 3.

What is the future value of $500 invested at 8 percent for five years under semi-annual compounding conditions?
Note: provide answer in full dollars/cents form, e.g., $123.45
To calculate the future value (FV) of an investment, we can use the formula:
FV = P(1 + r/n)^(nt)
Where:
FV = Future Value
P = Principal amount (initial investment)
r = Annual interest rate (as a decimal)
n = Number of compounding periods per year
t = Number of years
In this case, the principal amount is $500, the annual interest rate is 8% (or 0.08 as a decimal), and the compounding is done semi-annually (n = 2). The investment is held for 5 years (t = 5).
Using the formula, we can calculate the future value:
FV = $500 * (1 + 0.08/2)^(2*5)
FV = $500 * (1.04)^(10)
FV ≈ $734.66
Therefore, the future value of $500 invested at 8% for five years under semi-annual compounding conditions is approximately $734.66.

To find the volume of the solution needed to obtain 0.1 g of sodium chloride, we can use the following equation:
Volume (mL) = (Mass of sodium chloride (g)) / (Concentration of sodium chloride (g/mL))
In this case, the mass of sodium chloride is 0.1 g, and the concentration of sodium chloride is 0.05 g/mL.
Volume (mL) = 0.1 g / 0.05 g/mL = 2 mL

Write a linear regression and find the projected number of new cases for 2011.
The linear regression equation is y ≈ -30.64x + 883.47. The projected number of new cases for 2011 is approximately 524.
To find the linear regression equation that represents the given set of data, we need to find the equation in the form y = mx + b, where m is the slope and b is the y-intercept.
Using the given data points, we can calculate the slope (m) and the y-intercept (b) using the least squares method.
First, we calculate the mean of x and y:
mean(x) = (0 + 1 + 2 + 3 + 4) / 5 = 2
mean(y) = (885 + 865 + 823 + 793 + 745) / 5 = 822.2
Next, we calculate the differences from the means:
Δx = (x - mean(x))
Δy = (y - mean(y))
Using the differences, we can calculate the slope:
m = Σ(Δx * Δy) / Σ(Δx^2)
= ((0 - 2) * (885 - 822.2) + (1 - 2) * (865 - 822.2) + (2 - 2) * (823 - 822.2) + (3 - 2) * (793 - 822.2) + (4 - 2) * (745 - 822.2)) / ((0 - 2)^2 + (1 - 2)^2 + (2 - 2)^2 + (3 - 2)^2 + (4 - 2)^2)
≈ -30.64
Then, we calculate the y-intercept:
b = mean(y) - m * mean(x)
= 822.2 - (-30.64) * 2
≈ 883.47
Therefore, the linear regression equation that represents the data is y ≈ -30.64x + 883.47.
To find the projected number of new cases for 2011, we substitute x = 12 (since 2011 is 12 years since 1999) into the equation:
y ≈ -30.64 * 12 + 883.47
≈ 524.15
Rounding to the nearest whole number, the projected number of new cases for 2011 is approximately 524.

3log(x+2)+4log(x-4)- 2log(x+5)-3log(x-9)
The original expression simplifies to log((x+2)^3 * (x-4)^4) + log((x+5)^-2 / (x-9)^3) This represents a sum of Logarithms with different bases and arguments.
The given expression is 3log(x+2) + 4log(x-4) - 2log(x+5) - 3log(x-9). Let's simplify this expression using the properties of logarithms:
1. Product Rule: log(a) + log(b) = log(ab)
We can apply this rule to the first two terms:
3log(x+2) + 4log(x-4) = log((x+2)^3) + log((x-4)^4)
= log((x+2)^3 * (x-4)^4)
2. Quotient Rule: log(a) - log(b) = log(a/b)
We can apply this rule to the third and fourth terms:
-2log(x+5) - 3log(x-9) = log((x+5)^-2) + log((x-9)^-3)
= log((x+5)^-2 / (x-9)^3)
Therefore, the original expression simplifies to:
log((x+2)^3 * (x-4)^4) + log((x+5)^-2 / (x-9)^3)
This represents a sum of logarithms with different bases and arguments.

p^q is logically equivalent to
The logically equivalent statement to p → q is:
~q → ~p
How to find the logically equivalent statement?The conditional statement:
p → q
Assuming p and q are propositions, the conditional statement may be expressed as:
"If p holds true, then q follows suit. "
'
Whenever p is true, q is true as well. This implies that if q is false, then p must also be false.
We can rephrase this statement cleverly using the negative propositions, which include the opposite or contradictory statements.
~p and ~q
These mean:
Not p and Not q respectively.
Then the statement:
"If q is not true, then p is not true"
Is written as:
~q → ~p
So this is the logically equivalent statement.
