Answer:

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

Answer:

  5 units

Step-by-step explanation:

You want to know the side length of the rhombus with vertices (2, 0), (7, 0), (5, 4), and (10, 4).

You can find the length of the horizontal edges by counting the grid squares, or by subtracting the x-coordinates:

  7 -2 = 5

  10 -5 = 5

The slanted sides are each the hypotenuse of a 3-4-5 right triangle, so are also 5 units long. (You expect all of the sides of the rhombus to be the same length.)

Each side is 5 units long.

The answer is 5, 4.47, 5, and 8.94.

                The distance formula is d = √(x2-x1)^2 + (y2-y1)^2

                                    d = √(7-2)^2 + (0-0)^2

                                    d = √(5)^2 + (0)^2                

                                    d = √(25) + (0)

                                    d = 5

                                     d = √(5 - 7)^2 + (4 - 0)^2

                                      d = √(-2)^2 + (4)^2

                                      d = √4 + 16

                                      d = √20

                                      d = 4.47

                                      d = √(10 - 5)^2 + (4 - 4)^2      

                                      d = √25 + 0

                                      d = 5

                                       d = √(2 - 10)^2 + (0- 4)^2

                                       d = √(-8)^2 + (-4)^2

                                       d = √64 + 16

                                       d = √80

                                       d = 8.94

Therefore, each side of the rhombus has a length of 5, 4.47, 5, and 8.94.

What is a closed set ?

A Closed Set Math has a way of explaining a lot of things, and one of those explanations is called a closed set.

Closure property holds for addition and multiplication of whole numbers. The sum of any two whole numbers will always be a whole number, i.e. if a and b are any two whole numbers, a + b will be a whole number. The difference between any two whole numbers may or may not be a whole number. Hence, the whole numbers are not closed under subtraction.

According to the given question:

A set is closed under addition if you can add any two numbers in the set and still have a number in the set as a result. A set is closed under (scalar) multiplication if you can multiply any two elements, and the result is still a number in the set.

Given that,

A recipe calls for [tex]1\frac{1}{2}[/tex] teaspoons of cinnamon to make 2 dozen oatmeal cookies.

A fraction is numerical value that is a part of a whole. It is evaluated by dividing a whole into number of parts. For example, ½ represents half of a whole number or a thing.

Then,

We will find number of teaspoons needed to make one oatmeal cookies.

1 dozen = 12

2 dozens = 24

So,

We can write,

[tex]1\frac{1}{2}[/tex] divide by 24,

Convert mixed fraction into improper fraction:

[tex]\frac{3}{2}[/tex] divide by 24

Convert to division problem by flipping the second fraction as:

= [tex]\frac{3}{2}[/tex] * [tex]\frac{24}{1}[/tex]

= [tex]\frac{3}{48}[/tex]

= [tex]\frac{1}{16}[/tex]

Now, we will multiply amount needed for one cookie by 60 to find amount needed to make 60 cookies as:

= [tex]\frac{1}{16}[/tex] * 60

= [tex]\frac{15*4}{4*4}[/tex]

= [tex]\frac{15}{4}[/tex]

= [tex]3 \frac{3}{4}[/tex]

The size of the angle C is θ = 56°, given that BC and DE are tangents to the circle.

The 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.

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.

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.
