Paul cut a rectangular piece of paper. He then cut off a semi-circular piece from each end, as shown below. What is the area of the remaining paper? Use 3.14 for
Given that Paul has cut a rectangular piece of paper and then cut off a semi-circular piece from each end. We have to determine the area of the remaining paper.Since we don't have the dimensions of the rectangle piece of paper that Paul has cut. Therefore, we will assume that the rectangle is a square with a side length of 14 cm.
This assumption will make the calculation easier.
Now, the dimensions of the rectangle are:Length (l) = 14 cm ,Breadth (b) = 14 cm .The radius of each semi-circle = 7 cm (half of the side length) . Now, we can calculate the area of the rectangular piece of paper:
Area of the rectangle = Length x Breadth
= l x b
= 14 x 14
= 196 cm²
The total area of the two semi-circles is: Total area of two semi-circles
[tex]= 2 x (πr²)/2[/tex]
= πr²
= π x 7²
[tex]= 22/7 x 7 x 7[/tex]
= 154 cm²
The area of the remaining paper after cutting off two semi-circular pieces from the rectangle will be:
Area of the remaining paper = Area of the rectangle - Total area of two semi-circles
= 196 - 154
= 42 cm²
Therefore, the area of the remaining paper is 42 cm².

How many tins of blue paint does Luke need to buy?
(5)
Luke needs to buy 7 tins of blue paint. To determine the number of tins of blue paint Luke needs to buy, we need to calculate the total area of the wall and divide it by the coverage of 1 liter of paint.
The total area of the wall can be calculated by multiplying the length by the height:
Area = Length × Height = 7 m × 6 m = 42 square meters.
Since 1 liter of blue paint covers 8 square meters, we can calculate the number of tins needed by dividing the total area by the coverage per tin:
Number of tins = Total Area / Coverage per tin = 42 square meters / (8 square meters/liter) = 5.25 liters.
Since Luke can only buy paint in 2.5-liter tins, he needs to round up the number of tins to the nearest whole number. Therefore, Luke needs to buy 7 tins of blue paint.
Thus, Luke needs to buy 7 tins of blue paint.

Dawn is making an abstract painting with two triangles. The dimensions of the painting are shown below: Two triangles share the same height of 8 inches. One triangle has a base of 6 inches and the other is 10 inches. The total area of the two triangles is _____ square inches. Numerical Answers Expected! Answer for Blank 1:.
To find the total area of the two triangles, we need to calculate the area of each triangle and then add them together.
The formula for the area of a triangle is given by:
Area = (base * height) / 2
For the first triangle:
Base = 6 inches
Height = 8 inches
Area of the first triangle = (6 * 8) / 2 = 48 / 2 = 24 square inches
For the second triangle:
Base = 10 inches
Height = 8 inches
Area of the second triangle = (10 * 8) / 2 = 80 / 2 = 40 square inches
Now, we can find the total area of the two triangles by adding their individual areas together:
Total area = Area of the first triangle + Area of the second triangle
Total area = 24 square inches + 40 square inches = 64 square inches
Therefore, the total area of the two triangles is 64 square inches.

Let's assign variables to represent the ages of Sam, his brother, and their mother.
Let:
Sam's age = S
Brother's age = B
Mother's age = M
According to the given information, we can form the following equations:
1. Brother's age is 4 years older than Sam's age: B = S + 4
2. Mother's age is 3 times older than Sam's age: M = 3S
3. The sum of their ages is 74: S + B + M = 74

Abdicate has two electric train sets:A and B each trani
When the two sets are coupled together, the speed of the train is 96 km/h, and it takes 5 minutes to travel around the track. Abdicate has two electric train sets, A and B. Each train can be operated independently, or the two trains can be coupled together for double-head operation.
Abdicate has two electric train sets, A and B. Each train can be operated independently, or the two trains can be coupled together for double-head operation. Each set has a power car and two passenger cars, which can carry a total of 50 passengers. Set A has a top speed of 80 km/h, while set B has a top speed of 120 km/h. The sets operate on a circular track that is 4 km long.
If set A is operated independently, it takes 3 minutes to travel around the track. If set B is operated independently, it takes 2 minutes to travel around the track. If the two sets are coupled together for double-head operation, what is the speed of the train and how long will it take to travel around the track?
To determine the speed of the train when coupled together, we need to calculate the total distance travelled around the track and the total time taken.
When the two sets are coupled together, they operate as one train with a total of four cars, including two power cars and two passenger cars. Therefore, the total number of passengers that can be carried is 100.
Since the length of the track is 4 km, the distance travelled by the train will be twice that, or 8 km.
To determine the time taken for the train to travel around the track, we can use the formula:
time = distance/speed
When set A is operated independently, it takes 3 minutes to travel around the track, so the speed is:
speed = distance/time = 8 km / 3 min = 160/60 km/min = 2.67 km/min
When set B is operated independently, it takes 2 minutes to travel around the track, so the speed is:
speed = distance/time = 8 km / 2 min = 240/60 km/min = 4 km/min
To determine the speed of the train when coupled together, we can use the formula:
speed = distance/time = 8 km / t min
where t is the time taken for the train to travel around the track when coupled together.
We know that the total time taken for the train to travel around the track when coupled together is the sum of the times taken for set A and set B to travel around the track independently:
t = 3 min + 2 min = 5 min
Therefore, the speed of the train when coupled together is:
speed = distance/time = 8 km / 5 min = 96 km/h
So, when the two sets are coupled together, the speed of the train is 96 km/h, and it takes 5 minutes to travel around the track.

WILL GIVE BRAINLIST PLEASE HELP!
The volume of the square pyramid is 1568 cubic inches. Given that the pyramid has a perimeter of 56 inches, we can determine the length of each side of the square base.
To find the volume of a square pyramid, we need to know the length of the base and the height of the pyramid.
Since a square has all sides equal in length, we divide the perimeter by 4 (the number of sides) to find the length of each side:
Length of each side = 56 inches / 4 = 14 inches
Now, we need to find the height of the pyramid. The slant height given is the distance from the apex of the pyramid to the midpoint of one of the sides. To find the height, we need to use the Pythagorean theorem.
The slant height represents the hypotenuse of a right triangle, with one leg being half the length of the base side and the other leg being the height. Let's call the half of the base length "a" and the height "h."
Using the Pythagorean theorem, we have:
a^2 + h^2 = slant height^2
Since the base side is half the length of the perimeter, we have:
a = 14 inches / 2 = 7 inches
Plugging in the values, we get:
7^2 + h^2 = 25^2
49 + h^2 = 625
h^2 = 625 - 49
h^2 = 576
h = √576
h = 24 inches
Now that we have the length of the base (14 inches) and the height (24 inches), we can calculate the volume of the pyramid using the formula:
Volume = (1/3) * base area * height
The base area of a square is given by side length squared:
Base area = (14 inches)^2 = 196 square inches
Plugging in the values, we have:
Volume = (1/3) * 196 square inches * 24 inches
Volume = (1/3) * 4704 cubic inches
Volume = 1568 cubic inches

Write a function rule to represent the situation.
the total cost C for g grams of ham if each gram costs $5.77
Write a function rule using C and g as variables.
(Type an equation.)
The function rule representing the situation is C = 5.77g, where C is the total cost and g is the weight of ham in grams.
The function rule C = 5.77g represents the relationship between the total cost (C) and the weight of ham (g) in grams. In this situation, each gram of ham costs $5.77, so the total cost is obtained by multiplying the cost per gram ($5.77) by the weight of ham (g).
The equation C = 5.77g follows a linear relationship, where the cost (C) is directly proportional to the weight of ham (g). This means that as the weight of ham increases, the total cost also increases proportionally. For example, if we have 100 grams of ham, the total cost would be calculated as 5.77 * 100 = $577.
By using this function rule, we can easily determine the total cost of any given weight of ham. It provides a straightforward way to calculate the cost without needing to perform complex calculations or look up individual prices for different quantities. This equation can be useful in various situations, such as meal planning, budgeting, or determining the cost for commercial purposes.

The height of a toy rocket launched from a 64- foot observation tower as a function of elapsed time since the launch is modeled by the equation shown below h(t) =-16t
The height (h) of a toy rocket launched from a 64-foot observation tower as a function of elapsed time (t) is given by the equation h(t) = -16t.
The equation h(t) = -16t represents a mathematical model that relates the height of the toy rocket (h) to the elapsed time since the launch (t). In this model, the rocket's height decreases at a constant rate of 16 feet per second. The negative sign indicates that the rocket is descending rather than ascending.
Since the initial height of the toy rocket is 64 feet (from the observation tower), we can determine the height of the rocket at any given time by substituting the value of t into the equation. For example, if we want to find the rocket's height after 3 seconds, we substitute t = 3 into the equation: h(3) = -16 * 3 = -48 feet. This means that after 3 seconds, the toy rocket is 48 feet below the observation tower. Similarly, we can calculate the height at any other time by substituting the corresponding value of t into the equation.

Suppose you invest $850 in a certificate of deposit that is promised to make you 1% interest if you keep the money in the account for 16 months. How much money should be in the account after the 16 months has elapsed?
After 16 months, the amount of money in the account should be approximately $861.33.
To calculate the total amount in the account after 16 months with a 1% interest rate, we need to apply the formula for compound interest: A = P(1 + r)^t, where A is the final amount, P is the principal amount, r is the interest rate, and t is the time period.
In this case, you invest $850 as the principal amount with an interest rate of 1% (or 0.01 as a decimal). The money will be kept in the account for 16 months, so t = 16/12 = 4/3 years (since there are 12 months in a year).
Substituting the given values into the compound interest formula, we have:
A = $850(1 + 0.01)^(4/3)
Simplifying the exponent:
A = $850(1.01)^(4/3)
Evaluating the exponent:
A = $850(1.01005)
Multiplying:
A ≈ $861.33
after 16 months, the amount of money in the account should be approximately $861.33.

Consider a Hot Jupiter with a temperature of 3118 K orbiting the star Vega. At what wavelength (in nanometers) would the Hot Jupiter would be brightest?
The wavelength at which the Hot Jupiter would be brightest can be estimated using Wien's displacement law, which states that the peak wavelength of radiation emitted by a black body is inversely proportional to its temperature.
According to Wien's displacement law, the wavelength (λ) is given by the formula λ = b/T, where b is the Wien's displacement constant and T is the temperature in Kelvin.
Using the given temperature of the Hot Jupiter (3118 K) and the Wien's displacement constant, which is approximately equal to 2.898 × 10^6 nm·K, we can calculate the peak wavelength as follows:
λ = (2.898 × 10^6 nm·K) / (3118 K) ≈ 928.51 nm
Therefore, the Hot Jupiter would be brightest at a wavelength of approximately 928.51 nanometers.

What property allows one to set aside the order of operations how
The property that allows one to set aside the order of operations is called the Commutative Property. The order of operations is also known as the PEMDAS rule.
The order of operations, also known as the PEMDAS rule (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), is a fundamental principle in mathematics that dictates the sequence in which operations should be performed in an arithmetic expression. However, there are instances where the order of operations can be set aside or rearranged without affecting the final result. This is possible due to the Commutative Property, which applies to addition and multiplication.
The Commutative Property states that the order in which numbers are added or multiplied does not change the result. For addition, it means that the sum of two numbers remains the same regardless of the order in which they are added.
By applying the Commutative Property, one can rearrange the order of addition or multiplication operations, allowing for more flexibility in evaluating expressions. This property is particularly useful when simplifying or solving mathematical equations, as it enables us to change the order of terms without altering the final outcome. However, it's important to note that the Commutative Property does not apply to subtraction or division operations, and the order of operations should be followed strictly in such cases.
