The surface area to be covered with stucco is 25.91 square metres.
Explanation:To find the surface area to be covered with stucco, we need to calculate the area of each wall and subtract the areas of the car door, side door, and window. The garage has four walls, so we will calculate the area of each wall and add them together. The area of each wall is the product of its length and height. Once we have the total area of the walls, we can subtract the areas of the car door, side door, and window to determine the final surface area to be covered with stucco.
Wall 1: 5 m * 2 m = 10 m²
Wall 2: 5 m * 2 m = 10 m²
Wall 3: 5 m * 2 m = 10 m²
Wall 4: 5 m * 2 m = 10 m²
Total area of walls: 10 m² + 10 m² + 10 m² + 10 m² = 40 m²
Area of car door: 5 m * 2.3 m = 11.5 m²
Area of side door: 2.1 m * 0.9 m = 1.89 m²
Area of window: 1 m * 0.7 m = 0.7 m²
Final surface area to be covered with stucco: 40 m² - 11.5 m² - 1.89 m² - 0.7 m² = <<25.91=25.91>>25.91 m² (rounded to the nearest square metre).

a chain saw rental for $12 a day. A sharpening fee of $5 is charged for each rental. write an equation for the number of dollars (y) that must be paid to rent a chain for x days. How many days can one rent a chain saw for a cost of $125?
Answer:
y= 12x+5 and It would be 10 days.
Step-by-step explanation:
Y= total
+5 = each rental
X= # of days
125= 12x+5; x=10
The equation to determine the cost of renting a chainsaw for x days is y = 12x + 5. For a cost of $125, one can rent the chainsaw for 10 days.
To write an equation for the number of dollars (y) that must be paid to rent a chainsaw for x days, take into account the daily rental fee and the one-time sharpening fee. The daily rental fee is $12, and there is an additional one-time sharpening fee of $5 for each rental. The total cost y is therefore the sum of the daily rental fees for x days and the sharpening fee.
The equation is:
y = 12x + 5
To find out how many days one can rent a chainsaw for a cost of $125, we can set y equal to $125 and solve for x:
125 = 12x + 5
Subtract 5 from both sides to get:
120 = 12x
Divide both sides by 12 to solve for x:
x = 10
Therefore, one can rent a chainsaw for 10 days at a cost of $125.

A bicycle store costs $3250 per month to operate. The store pays an
average of $35 per bike. The average selling price of each bicycle is $85
How many bicycles must the store sell each month to break even?
Answer:
65 bikes
Step-by-step explanation:
The store buys the bikes that they sell for $35, and they sell them for $85, so in order to find the actual amount of money earned from one sale, you have to subtract how much they sell the bikes for by how much they bought them for, so:
85 - 35 = 50
Then, you divide the $3250 by the 50:
3250 / 50 = 65
So now we know that the store must sell 65 bikes a month to break even.

3. Explain the difference between (-10)^2 and -10^2. What are the values of each expression?
4. Explain the power of products property and give an example.
Answer:
1. [tex]2 \times 10^{- 4} = 2 \div 10^{4}[/tex]
2. [tex](- 10)^{2} = 100[/tex] and [tex]- 10^{2} = - 100[/tex]
3. [tex](a.b.c. ........)^{n} = a^{n}.b^{n}.c^{n}. ..........[/tex]
Example: [tex](30)^{4} = (2 \times 3 \times 5)^{4} = 2^{4} \times 3^{4} \times 5^{4}[/tex]
Step-by-step explanation:
1. We have [tex]2 \times 10^{- 4}[/tex], and we have to prove that this term is equivalent to [tex]2 \div 10^{4}[/tex].
Now, [tex]2 \times 10^{- 4}[/tex]
= [tex]2 \times \frac{1}{10^{4} }[/tex]
{Since we know the property of exponent as [tex]a^{- b} = \frac{1}{a^{b} }[/tex] }
= [tex]\frac{2}{10^{4} }[/tex]
= [tex]2 \div 10^{4}[/tex]
2. [tex](- 10)^{2} = (- 10) \times (- 10) = 100[/tex] and
[tex]- 10^{2} = - [(10) \times (10)] = - 100[/tex]

Then only multiplication of matrix exist.
Then the product of multiplication i.e Matrix C will have the order number of rows of Matrix A by number of columns of Matrix B
Let A be the first Matrix multiplied by matrix B
Matrix A is of order 2×3
Rows=2, column =3
Matrix B is of order 3×2
Rows=3, column =2

a bakery used 25% more butter this month than last month if the bakery use 240 kg of butter last month how much butter did he use this month
Answer: [tex]300\ Kg[/tex]
Step-by-step explanation:
Let be "x" the amount of butter (in kilograms) that the bakery used this month.
You need to divide the percentage by 100 in order to write it in decimal form. This is:
[tex]\frac{25}{100}=0.25[/tex]
According to the data given in the exercise, the total amount of butter they used last month is 240 kilograms.
Since 25% more butter was used this month than last month, you can write the folllowing equation:
[tex]x=240+(240 )(0.25)[/tex]
Evaluating, you get that the value of "x" is:
[tex]x=240+60\\\\x=300[/tex]
Therefore, the bakery used 300 kilograms of butter this month.
Final answer:
The bakery used 300 kg butter this month.
Explanation:
If a bakery used 25% more butter this month than last month and it used 240 kg of butter last month, then to calculate the amount of butter used this month, we need to add an additional 25% to the amount from last month. To find 25% of 240 kg, you multiply 240 kg by 0.25 (since 25% is the same as 0.25 when expressed as a decimal).
25% of 240 kg = 240 kg × 0.25 = 60 kg
Now, we add that 60 kg to the original 240 kg to find the total amount of butter used this month.
Total amount of butter used this month = 240 kg + 60 kg = 300 kg.
Therefore, the bakery used 300 kg of butter this month.

Expense Amount/Month Rent of Space $4000 Electricity $325 Advertising $375 Using the formula Profit = $40(number of hours) – (expenses) , calculate their profit for the month of January.
Answer:
8000
Step-by-step explanation:
Answer: The profit is $3300
Step-by-step explanation:
The data we have is:
They charge $40 per hour.
In january, the charged for 200 hours.
The expenses are:
rent $4000
electricity $325
advertising $375
if we want to know the balance we must calculate:
The total expenses are: $4000 + $325 + $375 = $4700
The amount that they won is: $40*200 = $8000
Then the profit will be:
P = $40*200 - ($4000 + $325 + $375) = $8000 - $4700 = $3300

y = x^2+ 3x + 1
A. X= 3/2
B. Y= 1

Step-by-step explanation:
Quadratic has a general form of:

Answer: 16 m
Step-by-step explanation:
We have the following data:
[tex]V=25 m/s[/tex] is the velocity of the object moving in uniform circular motion
[tex]t=1 s[/tex] is the time it takes to the object to go [tex]\frac{1}{4}[/tex] of a complete circle
We need to find the radius [tex]r[/tex] of the circle, and this can be found by the following equation:
[tex]V=\frac{2 \pi r}{T}[/tex] (1)
Where [tex]2 \pi r[/tex] is the circumference of the circle and [tex]T=4 t=4(1 s)[/tex] is the period for a complete circle.
Hence, isolating [tex]r[/tex] we have:
[tex]r=\frac{V T}{2 \pi}[/tex] (2)
[tex]r=\frac{(25 m/s)(4 s)}{2 \pi}[/tex] (3)
Finally:
[tex]r=15.9 m \approx 16 m[/tex] (4)

telephone company charges a fixed monthly rate plus a rate per megabyte of data used. The company charges $120 for 100 megabytes of data and $95 for 50 megabytes of data. An equation can be written to show the relationship between the total megabytes of data used (x) and the total monthly charges (y). Which of the following best describes the steps to draw the graph?
Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 0.50
Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 2
Draw a graph that joins the points (120, 100) and (95, 50) and has a slope = 2
Draw a graph that joins the points (120, 100) and (95, 50) and has a slope = 0.50
Answer:
The correct answer is A. Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 0.50
Step-by-step explanation:
1. Let's review the information given to us for solving the question:
Total of megabytes of date used = x
Total monthly charges = y
x₁ = 50 Megabytes, x₂ = 100 Megabytes
y₁ = US$ 95, y₂ = US$ 120
2. Let's find out the best description of the steps to draw the graph and the slope.
Slope = (y₂ - y₁)/ (x ₂- x₁)
Slope = 120 - 95/ 100 - 50
Slope = 25/50 = 1/2 = 0.50
Remember that the coordinates of the points in the line are written this way:
(x, y) ⇒ (Total of megabytes of date used, Total monthly charges)
The correct answer is A. Draw a graph that joins the points (100, 120) and (50, 95) and has a slope = 0.50
