Lamonte earned $269.10 at his job when he worked for 13 hours. How much money did he earn each hour?
Answer:
Step-by-step explanation:
To solve this problem, we need to divide the total amount of money Lamonte earned ($269.10) by the number of hours he worked (13 hours).
We can write this as an equation as follows:
earnings per hour = $269.10 / 13 hours
To solve for earnings per hour, we can divide both sides of the equation by 13:
earnings per hour = $269.10 / 13 hours / 13 = $269.10 / 13^2 = $269.10 / 169 = $1.60
Therefore, Lamonte earned $1.60 per hour.
What is the value of 994 1/3 According binomial theorem?
The value of 994 to the power 1/3 is 9.97.
The binomial theorem involves the method of expanding an expression which is raised to a finite power. A binomial theorem has its application in probability, algebra, etc.
A binomial expression is said to have two dissimilar terms.
The total number of terms in (x + y)ⁿ are n+1.
The expansion of (1 + x)ⁿ can be written as,
(1 + x)ⁿ = 1 + nx + [n*(n-1)]/2! x² + [n*(n-1)*(n-2)]/3! x³ + ....
Let us find the value of 994 to the power 1/3,
⇒ (993 + 1)¹/³
⇒ 1 + 993/3 + 993* 993* [1/3* (-2/3)]/2! + 993* 993* 993* [1/3* (-2/3)* (-5/3)]/3! + ...
⇒ 1 + 331 - 54780.5 + 60441151.67 - ...

When scale factor is greater than 1 your image gets?
By Dilation, if the scale factor is greater than 1 image gets enlarged.
What is Dilation?Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. The initial shape should be stretched or contracted during a dilatation. The phrase "scale factor" describes this transition.
Enlargement is the term used when a dilatation results in a larger image.
Reduction occurs when a dilatation results in a smaller picture.

Who has invented India?
Vasco da Gama has invented India
An invention is a brand-new or original product, process, composition, idea, or tool. A device, item, or method can be improved using an invention to boost functionality or cut costs. It could also be a brand-new idea. An concept can be patented if it is distinctive enough, either as a stand-alone innovation or as a major improvement over the work of others.
Portuguese explorer Vasco de Gama becomes the first European to reach India via the Atlantic Ocean when he arrives at Calicut on the Malabar Coast.
Da Gama sailed from Lisbon, Portugal, in July 1497, rounded the Cape of Good Hope, and anchored at Malindi on the east coast of Africa. With the aid of an Indian merchant he met there, he then set off across the Indian Ocean. The Portuguese explorer was not greeted warmly by the Muslim merchants of Calicut, and in 1499 he had to fight his way out of the harbor on his return trip home. In 1502, he led a squadron of ships to Calicut to avenge the massacre of Portuguese explorers there and succeeded in subduing the inhabitants. In 1524, he was sent as viceroy to India, but he fell ill and died in Cochin.

What two arguments did Mary Wollstonecraft?
Both men and women have duties to their families and duties to the state.
According to Wollstonecraft, women are important to the country because they educate their children and because they have the potential to be "companions" to their husbands rather than merely spouses. She also contends that women should have an education appropriate to their status in society.
She asserts that in God's view, men and women are on an equal footing. But these affirmations of equality conflict with her assertions that the strength and bravery of males are superior. It is now challenging to label Wollstonecraft as a modern feminist due to her equivocal views on gender equality.
Wollstonecraft differs from the majority of her male Enlightenment contemporaries because of her emphasis on the rights of women.

Wollstonecraft's emphasis on women's rights sets her apart from the rest of her male Enlightenment peers.

which expressions are equivalent to -6+3(2+(-4t) choose all that apply A)-12t , B) 12t-12, C) none of the above
The correct answer is A) -12t.
To evaluate this expression, we need to use the order of operations. The order of operations is a set of rules that specifies the sequence in which operations should be performed in a math expression to get the correct result. The order of operations is typically abbreviated as PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Following the order of operations, we first need to evaluate the expression inside the parentheses, which is 2+(-4t). This gives us 2-4t. Next, we need to perform the multiplication, which gives us 3(2-4t) = 6-12t. Finally, we need to perform the addition, which gives us -6+6-12t = -12t. Therefore, the expression -6+3(2+(-4t)) is equivalent to -12t.
Option B) 12t-12 is incorrect because the multiplication and addition operations are not performed in the correct order.
Option C) none of the above is incorrect because the correct answer is A) -12t.

Convert 400 liters per day to gallons per week show work
Answer:
400 liters per day is equivalent to 105.66 gallons per week.Step-by-step explanation:
To convert from liters per day to gallons per week, we need to use the conversion factors for these units. One gallon is equivalent to 3.785 liters, and one week is equivalent to 7 days.
We can use these conversion factors to write the following conversion equation:
1 gallon/week = (3.785 liters/gallon) / (7 days/week)
We can then use this equation to convert 400 liters per day to gallons per week by multiplying the number of liters per day by the conversion factor. This gives us:
400 liters/day * (1 gallon/week) / (3.785 liters/gallon) / (7 days/week)
We can simplify this expression by canceling out the units that appear on both the numerator and denominator. This gives us:
400 / 3.785 / 7 = 105.66
Therefore, 400 liters per day is equivalent to 105.66 gallons per week

The size of the angle C is θ = 56°, given that BC and DE are tangents to the circle.
Tangent to a circle theoremThe tangent to a circle theorem states that a line is tangent to a circle if and only if the line is perpendicular to the radius drawn to the point of tangency
Considering the Isosceles triangle ∆AOB and its exterior angle ∠BOD;
∠BOD = 180° - 2(48) {exterior angle of a triangle equals 2 opposite interior angles}
∠BOD = 96°
If the line DE is extended to line BC at E' we will have a quadrilateral BODE' and a triangle ∆CE'D, hence;
∠B = ∠D = 90° (angles between radius and lines tangent to the circle)
so;
∠BOD + ∠OBD + ∠ODE' + ∠BE'D = 360° {sum of interior angles of a quadrilateral}
96° + 90° + 90° + ∠BE'D = 360°
276° + ∠BE'D = 360°
∠BE'D = 360° - 276° {subtract 276° from both sides}
∠BE'D = 84°
Considering triangle ∆CE'D;
∠DE'C = 180° - 84° {sum of angles on a straight line}
∠DE'C = 96°
We thus derive θ using the triangle ∆CE'D;
θ = 180° - (28 + 96)° {sum of interior angles of a triangle}
θ = 180° - 124°
θ = 56°
In conclusion, we have derived the size of the angel θ as 56° by proper application of the tangent to a circle theorem.
