Step-by-step explanation:

Answer:

1.55 lbs

Step-by-step explanation:

take 6 ⅕ and divide it by 4 since there are 4 bags, you can also turn it into a decimal (6.2)

Answer:

1.55lbs of cat food in each bag

Step-by-step explanation:

question 1) simply divide the total amount of cat food by the number of bags it is placed in.

6 1/5lb divided by 4

[tex]6 \frac{1}{5} \div 4[/tex]

when dividing fractions, the divisor is flipped over and the sign changes to multiplication.

[tex]6 \frac{1}{5} \times \frac{1}{4} [/tex]

[tex] \frac{31}{5} \times \frac{1}{4} [/tex]

therefore=

[tex] \frac{31}{20} [/tex]

or as a decimal 1.55lbs

The angle of elevation made from the eyes of the observer to the top of the tower is 45°.

The angle of elevation is the angle formed by the horizontal line of sight and the upward line of sight.

For the given question;

The angle of elevation of the top of the tower to the eyes of the observer is needed.

Thus, for this subtract the height of the observer to the height of tower;

height from the eyes to the tower is 22 - 1.5 = 20.5 m.

Thus, apply the trigonometric rule to calculate the angle;

tan Ф = perpendicular/base

perpendicular is the height of tower from the eyes of boy = 20.5 meter.

base is the distance of the tower from the boy = 20.5 meter.

Put the values;

tan Ф = 20.5/20.5

tan Ф = 1

Ф = 45°.

Thus, the angle of elevation made by the eyes of the observer to the top of the tower is  45°.

The required answer for 25:4 and 45:10 as a complex fraction is 1/(4/25) and 1/(2/9).

Fractions represent the parts of a whole or collection of objects.

A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.

Now given ratio are,

25:4 and 45:10

Now converting the given ratio into fraction,

25:4 = 25/4

and,

45:10 = 45/10

Now for 25/4 we have,

Numerator = 25

Denominator = 4

Now dividing numerator and denominator by 25 we get,

Numerator = 25/25 = 1

Denominator = 4/25

Thus, the complex fraction of 25/4 we get is,

25/4 = 1/(4/25)

Similarly for 45/10

Numerator = 45

Denominator = 10

Now dividing numerator and denominator by 45 we get,

Numerator = 45/45 = 1

Denominator = 10/45 = 2/9

Thus, the complex fraction of 25/4 we get is,

45/10 = 1/(2/9)

Thus, the required answer for 25:4 and 45:10 as a complex fraction is 1/(4/25) and 1/(2/9)

Finding the missing angle of the figure, the value of m∠DKL is 110°

Two rays that have a common endpoint and are referred to as the angle's sides and vertices, respectively, form an angle. Two rays can form angles in the plane where they are positioned. Angles are also produced when two planes intersect. These angles are dihedral.

given,

m∠DKL = (21x + 5)°

m∠JKD = (4x + 2)°

and

m∠JKL = 132°

By angle sum property of angles

m∠DKL + m∠JKD =  m∠JKL

substituting the values, we get

(21x + 5)° + (4x + 2)° equals  132°

(21x + 4x + 5 + 2)° =  132°

(25x + 7)°=  132°

(25x)° =  132° - 7°  

x = 125° / 25°

x = 5

now, the value of m∠DKL

m∠DKL = [21 (5) + 5]°

m∠DKL = 105° + 5°

m∠DKL = 110°

Hence the value of m∠DKL is 110°

Karen while putting a fence around the L shaped garden will need about 22.3 ft which is the exact perimeter of this field, with its dimensions as given as 2.1ft by 7.8ft by 5.5ft by2.7ft of the garden.

Any kind of closed path that covers, encircles, or outlines a full one-dimensional length or a two-dimensional shape is called as a perimeter.

The circumference of a circle or an ellipse is referred to as its perimeter. There are varied uses in real life for the perimeter calculations.

For example, in case of a rectangle, there are two equal lengths and two equal widths in a rectangle. Then we must sum up all the lengths of the rectangle’s four sides in order to get its final perimeter.

Since there are like two of each side length, it is easy to accomplish this perimeter by simply adding the length and width and then multiplying the result by two.

In this problem,

Total perimeter = 2.1 + 5.1 + 2.1 + 2.5 + 2.7 + 7.8

= 22.3 ft

Thus, the perimeter has been calculated in total as 22.3 ft.

The graph which does not represent y as a function of x is (B) as a line drawn can't touch the graph at two points.

The function that dose not show y as a function of x.

Y is a function of X, means that a certain variable magnitude or phenomenon Y is determined/caused by another magnitude or phenomenon X, such that the behavior of X will affect that of Y. In logic, a function symbol is a logical symbol that may be applied to an object term to produce another object term.

If a vertical line is drawn such that it touches more than one place, then it is not a function of x.

Here also if a vertical line will be drawn it will touch two places in the curve.

So, in figure B, y is not a function of x.

A variable's magnitude or phenomena Y is determined by or caused by a different variable's magnitude or phenomenon X, meaning that X's behavior will have an impact on Y's. A function symbol in logic is a logical symbol that can be used to transform one object term into another.

A vertical line is not a function of x if it is drawn so that it touches many locations.

The principal investment required to get a total amount of $250,000.00 rounded to the nearest cent is $81569.95.

The formula for calculating compound interest is expressed as;

A = P(1 + r/n)^(n*t)

P = A / e^(r*t) compounded continuously

Given the data in the question;

Plug the given values into the equation above and solve for P

P = A / e^(r*t)

P = 250,000 / e^( 0.14 × 8 )

P = 250,000 / e^( 1.12)

P = 250,000 / e^( 1.12)

P = $81569.95

Therefore the principal investment required to get a total amount of $250,000.00 rounded to the nearest cent is $81569.95.
