The lowest price that Mike should pay for 7 days' juice consumption is £6.16.
How to calculate the cost per item?In order to calculate the cost of one item, divide the total cost of items by the total number of items. It is also called the unit rate of that item.
The per day requirement of Mike is 2/5 liters.
Then, for 7 days the requirement is 2/5 × 7 = 14/5 liters.
The rate of juice for 2 liter and 1 liter carton are given as £4.40 and £2.60 respectively.
Then, the unit rate for both the carton is given by 4.40/2 = £2.20 and £2.60 respectively.
Since, the two liter carton has less unit rate, it can be used for 7 days consumption.
Now, the lowest price paid by mike is given as,
Unit rate of 2 liter carton × Total requirement of milk for 7 days
⇒ 2.20 × 14/5
⇒ 6.16
Hence, the lowest price paid by mike is £6.16.

How many reflections symmetries does a decagon shaped like a five- pointed star have? How many rotational symmetries does the decagon have? Draw the reflection symmetries on the decagon.
Decagon has a total of 5 reflection symmetries
A reflection symmetry of a shape is a line that divides the shape into two halves that are mirror images of each other. To find the number of reflection symmetries of the decagon, we can draw lines through the center of the decagon that pass through pairs of opposite vertices.
We can draw a total of 5 lines through the center of the decagon that pass through pairs of opposite vertices. Each of these lines is a reflection symmetry of the decagon. Therefore, the decagon has a total of 5 reflection symmetries.
A rotational symmetry of a shape is a rotation about a fixed point that leaves the shape unchanged.
To find the number of rotational symmetries of the decagon, we can count the number of times we can rotate the decagon about its center by 36 degrees (which is the central angle of the decagon) and obtain the same shape. In this case, we can rotate the decagon about its center by 36 degrees 10 times and obtain the same shape each time.
A decagon shaped like a five-pointed star has 10 sides and 5 vertices, and it looks like this:

Drag each object to show whether cost is proportional to area in the situation represented.
Increasing the area from 400 to 600 (50%) results in an increase in cost from 500 to 750 (50% increase), which shows that the cost is not proportional to the area.
In a situation where cost is proportional to area, the relationship between cost and area is said to be directly proportional. Direct proportionality means that if the value of one variable (in this case, area) is multiplied by a certain factor, then the other variable (in this case, cost) will also be multiplied by the same factor. The mathematical formula for direct proportionality is [tex]y = kx,[/tex] where y and x are the two variables, and k is the constant of proportionality. If the relationship between the variables is not proportional, then it is a non-proportional relationship.
The objects are proportional if increasing one quantity by a certain factor results in the other quantity increasing by the same factor. In this case, cost is proportional to area if doubling the area would double the cost. Based on the table, we can see that the cost is not proportional to the area since the cost does not increase by the same factor as the area. For example, increasing the area from 400 to 800 (double) results in an increase in cost from 500 to 1000 (also double). However, increasing the area from 400 to 600 (50%) results in an increase in cost from 500 to 750 (50% increase), which shows that the cost is not proportional to the area.

The triangle inequality theorem explains the connection between a triangle's three sides. This theorem states that for any triangle, the sum of the lengths of the first two sides is always greater than the length of the third side. In other terms, this theorem states that a straight line is always the shortest distance between any two places.
Given, Mr Hansen has three sticks that measure 5 inches, 10 inches and 17 inches

One of the same side interrier angles of two paralell lines is 20 degrees less than the other sameside interior angle. Find the measures of the two angles.
Interior angles on the same side are supplementary, which means they add up to 180°. We can write the equation as follows and refer to the two angles as x° and (x + 20)°.
What are angles?When two rays are linked at their ends, they create an angle in geometry. The sides or arms of the angle are what are known as these rays.
When two lines meet at a point, an angle is created.
An "angle" is the measurement of the "opening" between these two rays. It is symbolized by the character. The circularity or rotation of an angle is often measured in degrees and radians.
Angles are a common occurrence in daily life.
Angles are used by engineers and architects to create highways, structures, and sports venues.
According to our question-
x + x + 20 = 180
2x + 20 = 180
2x = 160
If x = 80, the angles are 80° and 80 + 20 = 100°, respectively.

What is bacterial growth?here growth means increases in the number of bacterial populations with respect to time. Generally, the rate of growth of bacteria is occurred exponentially. We use the following exponential equation to calculate the number of bacteria.
N= N° e∧(kt)
How to calculate the initial sizes of bacteria and the population after certain time period?In the above equation, N and N° denotes the number of populations after t minutes and initial time respectively.
k is a constant of proportion
t is the time in minutes
as per given data, the number is doubled after 10 min
N=2N°, t=10
2N°=N° e∧(k10)
2= e∧(k10)
㏑2 = k10 [we took ㏑ in both side]
k= 0.0693
after t= 80 min, the population N= 80000
now using the equation, 80000=N° e∧(k80)
as k=0.0693, N°= 313
the initial number is 313'
after t=5 hours =300 min, the population will be
N= 313 e∧ (0.0693x300)
N = 3.346×10¹¹

where,
amplitude is A
Frequency is B
period is 2π/B
phase shift is C (positive is to the left)
vertical shift is D
Step 1:
Identify
5 cos(2x) + 3 → Acos(B(x + C )+ D
Hence
A = 5 = Amplitude
B = 2.C = 0. So,
Period = 2π / B
= 2π / 2 = π
Period = π
Frequency = B = 2
Vertical shift = D = 3
Step 2:
Midline
The equation of the midline of periodic function is the average of the maximum and minimum values of the function.
a) we have a maximum when
cos(2x) = 1
x =0, because (cos 0) = 1 Now, replace
y = 5 cos(2x) + 3
y = 5cos(2. 0 ) +3
= 5.1 + 3
= 8
So, the maximum is 8
b) we have a minimum when
cos(2x) = -1
x = π/2 , because
cos(2.π/2) = cos(π) = -1
Now, replace
y = 5cos(2.π/2) + 3
= 5. (-1) + 3

Perpendicular Length,
=Vertical Distance of eyes - Vertical distance of the bottom edge of the mirror
=1.64-0.38
=1.26 m
Angle of Reflection,
= Perpendicular Distance / Distance between the person and mirror
tan θ=1.26/2.30
tan θ=0.548
θ=tan⁻¹(0.548)
θ=28.72°
Angle of Incidence = 90 degrees - angle of reflection
=90-28.72
γ=61.28°
Angle of incidence,
=Horizontal distance to floor / height of mirror
tan 61.28°=x/0.38
x=0.38*tan 61.28°
x=0.38*1.825
x=0.6935 m
The horizontal distance to the base of the wall is 0.6935 m when the floor stands 2.30 m in front of a vertical plane mirror whose bottom edge is 38 cm above the floor.
