Answer:

0.8 euro

Step-by-step explanation:

Suppose the price of bottle of lemonade is x, when the bottle of water costs y.

Four bottles of lemonade cost 4x, two bottles of water cost 2y

4x+2y=2.45

Two bottles of lemonade cost 2x, four bottles of water cost 4y

2x+4y= 2.35

These equations( 4x+2y=2.45 and 2x+4y= 2.35) are simultaneous, so

multiply the first one by -2

-8x-4y=-4.9

-8x-4y+2x+4y= -4.9+2.35

-6x=-2.55

x=0.425 euro - the cost of bottle of lemonade

y=(2.45-4*0.425)/2

y=0.375 euro - the cost of bottle of water

0.425+0.375= 0.8 euro - the total cost  of one bottle of

lemonade and one bottle of water

Answer:

price of lenonade bottle is 0.425

price of water bottle is 0.375

Step-by-step explanation:

In explaination, 'x' is the value of lemonade bottle and 'y' is the value of water bottle.

Answer:

A≈1633.63

Step-by-step explanation:

d Diameter 26

h heigth 7

A=2πd

2h+2π(d

2)2=2·π·26

2·7+2·π·(26

2)2≈1633.62818

Answer:

Step-by-step explanation:

The perimeter (P) of a rectangle is equal to the sum of twice the length and twice the width.

For this problem, let x be the width.

Then because the length is 2 less than 3 times the width

The length is 3x - 2

Therefore, P = 2x + (2)(3x - 2) = 36

Solving this for x gives:

2x + 6x - 4 = 36

8x - 4 = 36

8x = 40

x = 5

Therefore, the width = x = 5 feet

And the length = 3x - 2 = (3)(5) - 2 = 13 feet

Hey there! :)

Domain is the set of all x-values while Range is the set of all y-values!

When we want to find the domain of functiom through graph, we can do by finding the left point first and then the right point in x-plane or horizontal line.

The left point is (-4,0) and the right point is (4,0)

Since both points are opened, we use ( and ) instead.

Hence, the domain is (-4,4)

Next is finding range. Range is similar to Domain but y-value. You can find the range by finding the minimum point first then maximum point in y-plane or vertical line.

From the graph, minimum point is (-1,-3) and maximum point is (-4,0),(1,0) and (4,0)

Remember that we use the y-coordinate point for range! The minimum point and maximum point (1,0) both are closed dot. Since they are closed dot, we use [ or ].

Therefore, the range is [-3,0]

In conclusion, the answer is first choice.

Let me know if you have any questions!

The percentage of males in the distribution is 46% and it represents the marginal distribution of males in the population.

To obtain the percentage of males out of the total respondent ; we use the relation ;

Number of males / total number of respondents

Number of males = (31 + 34 + 64 + 109 + 75) = 313

Number of females = (22 + 70 + 70 + 112 + 98) = 372

Total number of respondents = (number of males + number of females) = (313 + 372) = 685

Percentage of males = (313 / 685) × 100% = 45.69% = 46%

This percentage represents the marginal distribution of males as it is the percentage of just one of the random variables.

If the percentage represents more than one such that one variable depends on the other, then it would have represented a conditional distribution.

Answer:  72 degrees, if I read the question correctly.

Step-by-step explanation:  The sum of all the angles in a complete circle is 360 degrees.  Angles oppor=site each other are equal, so we have two angles of 95 degrees each, for a total of 190.  That leaves 170 for the other two angles, which are also equal,  So they must 85 each.  If I read the diagram correctly, it assigned this angle equal to d + 13,  I have no clue why, but if so:

 d + 13 = 85

 d = 72 degrees

If 0 is subtracted from any number, then the result is the Number itself.

Hi! I'm happy to help!

To solve this, we have to use the order of operations, or PEMDAS. (parenthesis, exponents, multiplication or division, and addition or subtraction)

We will start out with parenthesis. Since there are no expressions inside of the parenthesis, we can remove them.

But, before we do that, we have a positive negative, the negative form of positive is negative, so we remove the plus sign as well as the parenthesis.

1.7+(-5)+(3.27)=

1.7-5+3.27=

Now since we have no exponents, multiplication, or division, we move on to addition or subtraction. We have some of both, so we move from left to right.

Our first equation is 1.7-5, so we do that first.

1.7-5+3.27=

-3.3+3.27=

Now, we only have one addition problem left, -3.3+3.27, so we'll do that.

-3.3+3.27=

-0.03

After this equation is fully simplified, we are at -0.03!

Answer:

[tex]6i[/tex]

Step-by-step explanation:

We want to write the conjugate of the complex number:

[tex]-6i[/tex]

Recall that the conjugate of a complex number in the form a + bi is a - bi, and vice versa.

We can rewrite our complex number as:

[tex]\displaystyle 0 - 6i[/tex]

Hence, a = 0 and b = 6.

Then its conjugate will be:

[tex]0 + 6i = 6i[/tex]

A function in mathematics is a relation between two sets such that each element of the first set is matched to exactly one of the second set element

The correct option for the maximum velocity of the object is the option;

13 cm/s

The reason for the selection is as follows:

The known parameters of the motion of the vehicle are:

The type motion of the vehicle = Repetitive back and forth

The path of the motion of the object = Along a straight line

The function that gives the velocity in centimeters per second (cm/s) is given as follows;

[tex]v(t) = \mathbf{13 \cdot sin \left(\dfrac{\pi}{45} \cdot t \right)}[/tex]

Where;

t = The time in seconds (a set of the input variables of the function)

v(t) = The velocity of the object (the output variables of the function)

The velocity of the object, v(t), depends (is given by) on the time t, therefore;

The maximum velocity is given at a particular value of t, which together with [tex]\dfrac{\pi}{45}[/tex] is operated by the sine function

The maximum output value of the sine function = 1, therefore;

[tex]\mathbf{Maximum \ value \ of \ sin \left(\dfrac{\pi}{45} \cdot t \right)_{max}} = 1[/tex]

[tex]The \ maximum \ velocity \ v(t)_{max}} = 13 \times sin \left(\dfrac{\pi}{45} \cdot t \right)_{max} = 13 \times 1 = \mathbf{ 13}[/tex]

The units of the of the function is cm/s

Therefore, the maximum velocity of the object is 13 cm/s
