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.

The product of 576 and 684 is irrational or rational
The product of 576 and 684 is a rational number since it results in an integer, which is a subset of rational numbers.
Explanation:The product of 576 and 684 is asked to be classified as rational or irrational. The multiplication of two integers will always produce another integer, as is the case with 576 multiplied by 684. Since all integers are rational numbers (they can be expressed as the ratio of two integers), the product, in this case, is also a rational number.
Therefore, the product of 576 and 684 is rational because it can be expressed as a ratio of the two integers (the product itself over 1), fitting the definition of a rational number which includes integers, fractions, finite decimals, and repeating decimals.
Final answer:
The product of 576 and 684 is a rational number because the multiplication of two integers always results in another integer.
Explanation:
The question asks whether the product of 576 and 684 is rational or irrational. A rational number is a number that can be expressed as a ratio of two integers. Since both 576 and 684 are integers, their product will also be an integer, as the multiplication of two integers always results in another integer. Therefore, this product is definitely a rational number. An irrational number, by contrast, cannot be expressed as such a ratio, and is typically found with non-repeating, non-terminating decimal expansions or with numbers like the square root of a non-square number. However, as there is no square root or any other irrational operation involved in multiplying 576 and 684, the result is rational.

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.
Max bought a 100-page journal and writes 1 page per day. Pat bought a 200-page journal and writes 3 pages per day. The equation below can be solved to find the number of days ( d ) until they will have the same number of pages left in their journals. −d + 100 = −3d + 200 In how many days ( d ) will Max and Pat have the same number of pages left in their journals?
Answer:
d=50
Step-by-step explanation:
-d+100=-3d+200
Subtract 100 from both sides
-d+100-100=-3d+200-100
Simplify
-d=-3d+100
Add 3d to both sides
-d+3d=-3d+100+3d
Simplify
2d=100
Divide both sides by 2
\frac{2d}{2}=\frac{100}{2}
Simplify
d=50
Answer:
In 50days
Step-by-step explanation:
Since the equation below can be used to find the number of days (d) until they will have the same number of pages left in their journals −d + 100 = −3d + 200, this equations will be solved to get 'd'
Given the equation;
−d + 100 = −3d + 200
Collecting like terms we will have;
-d+3d = 200-100
2d = 100
d = 50
This shows that Max and Pat will have the same number of pages left in their journals in 50days.

ALWAYS use significant figure rules. Remember that these rules apply to all numbers that are measurements. An object moves in uniform circular motion at 25 m/s and takes 1.0 second to go a quarter circle. What is the radius of the circle? R = _____ m 0.063 m 0.99 m 16 m 50. m
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:

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)

y = x^2+ 3x + 1
A. X= 3/2
B. Y= 1
C. X=3
D. X= -3/2
Answer:
D
Step-by-step explanation:
Quadratic has a general form of:
[tex]ax^2 + bx + c = 0[/tex]
The quadratic given here is:
[tex]y = x^2 + 3x + 1[/tex]
