Dan is left with £66 after the total spending.
What is referred as the total expenses?An expense is the amount of operations incurred by a business in order to generate revenue.
It is simply described as the amount of money required to obtain something. "It costs to make money," as the adage goes.Expenses can be classified in a number of ways. Fixed expenses, including such rent or mortgage, are those that don't change in response to changes in production. Expenses can also be described as variable expenses, which change in response to changes in production. Utilities as well as the cost of selling goods are examples of these.As for the given question;
The total earning per week is £495.
Spending on rent is 1/5.
1/5 of £495 = 495/5 = 99
Spending on rent is £99.
Now, spending on food is 2/3 of £495.
Food spending = (2/3)×495 = £330
Let the money left is 'x'.
Total expenses = Total income
food cost + rent cost + saving = 495
99 + 330 + x = 495
x = 495 - 429
x = 66

A projectile’s motion can be modeled by the quadratic equation: h left parenthesis t right parenthesis space equals space minus g t squared space plus space v subscript 0 t space plus thin space h subscript 0 g is 16 if in feet and 9 if in meters;; t = time in second elapsed from release of projectile; v0= initial velocity; h0 = initial height. Write the equation for a projectile that is dropped (v0 = 0) from a height of 100 ft. When will it hit the ground? Change the equation to reflect that the object is thrown upward from an initial height of 6 ft at 30 ft/sec. When will the object be back at the starting height? Hit the ground?
The projectile motion equation [tex]h(t) = - g \cdot {t}^{2} + v_{0}\cdot {t} + h_{0}[/tex], gives;
First part;
The object will hit the ground in 2.5 secondsSecond part;
The object will be back at the starting point in 1.875 secondsThird part;
The object will hit the ground in approximately 2.06 secondsHow can the projectile motion information be found?The quadratic equation that represents the projectile motion can be presented as follows;
[tex]h(t) = - g \cdot {t}^{2} + v_{0}\cdot {t} + h_{0}[/tex]
g = 16 ft./s² or 9 m/ s²
First part;
When
[tex] v_{0} = 0 \: and \: h_{0} = 100 \: ft.[/tex]
We have;
h(t) = -16•t² + 100
When the object hits the ground, we have;
h(t) = 0, which gives;
0 = -16•t² + 100
Therefore;
16•t² = 100
t² = 100 ÷ 16 = 25/4
t = √(25/4) = 5/2 = 2.5
The time it takes the object to reach the ground is 2.5 seconds.Second part;
The direction in which the object is thrown = Upwards
Initial height of the object, [tex] h_{0} = 6 \: ft[/tex]
Initial speed of the object, [tex] h_{0} = 30 \: ft/sec[/tex]
The equation of the projectile motion is therefore;
h(t) = -16•t² + 30•t + 6
Which gives;
When the object is at its starting height of 6 feet, h(t) = 6, which gives;
6 = -16•t² + 30•t + 6
-16•t² + 30•t = 0
A solution to the above equation is t = 0
The other solution is found as follows;
-16•t² + 30•t = 0
-16•t + 30 = 0
30 = 16•t
t = 30/16 = 1.875
The object will be back at the starting height at 1.875 secondsThird part;
When the object hits the ground, we have;
h(t) = 0, which gives;
0 = -16•t² + 30•t + 6

Suppose the tank is halfway full of water. the tank has a radius of 2ft and is 5 ft long. calculate the force on the ends due to the hydrostatic pressure.
The force on one of the ends due to hydrostatic pressure is 332.8lb.
How is a hydrostatic pressure produced?
The force that is produced by water that is still or at rest is known as hydrostatic pressure. It is the consistent pressure that water puts on the walls of your basement. While runoff pouring down a hill might cause hydrostatic pressure, the soil around the foundation of your home usually causes it.The force on one of the ends due to hydrostatic pressure is 332.8lb
Data;
Density = 62.4 lb/ft^3
length = 4ft
radius = 2ft
Force Due to Pressure
The force due to hydrostatic pressure can be calculated as
From the attached diagram
F = Pressure * area
density = 62.4 lb/ft³
depth of water = 2- y
pressure = ( 2- y ) ( 62.4)
= 124.8 - 62.4
We can proceed as
x² + ( y - 2)² = 2²
x² = 4 - ( y - 2)²
x = ± √4y - y²
this implies that
2x = 2 √4y - y²
The area is given as
δA = ( 2x) * δy
δA = 2√4y - y² δy
The force would be given by
δF = ( 2- y ) ( 62.4) (2 √ 4y - y²)δy
The total force is given by
F = [tex]\int\limits^2_0 {( 2 - y)} \, (62.4) ( 2\sqrt{4y - y^{2} } dy[/tex]
F = 124.8 [tex]\int\limits^2_0 {( 2-y)} \,( \sqrt{4y - y^{2} } dy[/tex]

Line m passes through points (-1,4) and (5,k). Y-7=-3/2(X+4) is perpendicular to line m. Find the value of K.
Line m passes through the point value of k is -1/3.
Now let us find the slope of the equation using the slope equation of line:
y = mx + b,
From the given slope let’s find y,
y-7= -3/2(x+4)
y-7= -3/2x - 6
y= -3/2x + 1
=-1 / (-3/2)
=2/3
As these two lines are perpendicular the product of the slopes is -1.
m= 2/3 , y=-1
Line m is given as y=2/3 x +b
As the line m passes through the points
(-1, 4) and (5, k)
X=4,
To find b
-1 = 2/3 * 4+b
-1=8/3+b
b=-11/3
By substituting all the values in the formula we get value of k,
Line m : y=2/3*-11/3
When x=5
k=y=2/3*5-11/3
=10/3-11/3
=-1/3
K = -1/3
A perpendicular is a straight line that makes an angle of 90° with any other line. 90° is also known as a right angle and is marked through a little square among two perpendicular lines.
Hence, the value of k is -1/3. The two lines intersect at a right angle, and hence, are stated to be perpendicular to each other.

Answer: k=8
Step-by-step explanation:
To find the value of k in the equation y-7=-3/2(x+4), we need to determine the slope of the line given by this equation.
First, let's rewrite the equation in slope-intercept form (y = mx + b),
where m is the slope and b is the y-intercept:
y - 7 = -3/2(x + 4) y - 7 = -3/2x - 6 y = -3/2x - 6 + 7 y = -3/2x + 1
Comparing this equation with the general slope-intercept form, we can see that the slope (m) is -3/2.
Since the line y - 7 = -3/2(x + 4) is perpendicular to line m, we know that the slopes of the two lines are negative reciprocals of each other.
The negative reciprocal of -3/2 is 2/3.
Therefore, the slope of line m is 2/3.
We know that line m passes through the points (-1, 4) and (5, k). Using the slope-intercept form, we can write the equation of line m as:
y = 2/3x + b Substituting the coordinates (-1, 4) into the equation,
we can solve for the y-intercept (b): 4 = 2/3(-1) + b 4 = -2/3 + b 4 + 2/3 = b 12/3 + 2/3 = b 14/3 = b Therefore, the equation of line m is: y = 2/3x + 14/3 Substituting the x-coordinate 5 and solving for k: k = 2/3(5) + 14/3 k = 10/3 + 14/3 k = 24/3 k = 8 Hence, the value of k is 8.

x = -4 (multiply each side by 2\5)
Find y:
y = [tex]-\frac{1}{2}.(-4)-7[/tex]
= -5
so, the point is (-4,-5).
Now using the Distance Formula, find the distance between the points (-4,-5) and (0,−7).

Igor has not been skiing in 10 years. however, when he gets on his skis, his body remembers exactly how to ski. the kind of memory that makes it possible for him to remember how to ski is procedural.
What is procedural memory?Procedure memory exists a kind of implicit memory (unconscious, long-term memory) that helps people carry out particular tasks without thinking about their previous experiences. It frequently resides below the consciousness level and controls the actions we take. The automatic retrieval and use of procedural memories, which are relied upon when appropriate, is necessary for the execution of integrated motor and cognitive functions, such as tying shoes, reading, and flying an airplane. Procedural memories are recovered and used without any conscious control or attention being needed. Procedural learning, or repeatedly completing a challenging activity until all required brain networks are able to coordinate to complete the job automatically, is how procedural memory is established.To learn more about procedural memory, refer to:

From 1890 through 1990, the number of men M and women W in the US labor force can be modeled by the following equations, where t is the number of years since 1890. M=0.0016t^2 + 0.315t + 19.467 W= 0.007t^2 - 0.228t + 5.908 Find a model for the total number of people in the US Labor force.
The model for the total number of people in the US Labor force is T = -0.0054t² + 0.087t + 13.559 .
In the given question
the number of men "M" in the US labor force is modelled by the equation ,
M = 0.0016t² + 0.315t + 19.467 ...(i)
and
the number of women "W" in the US labor force is modelled by the equation ,
W= 0.007t² - 0.228t + 5.908 ...(ii)
Let "T" denoted the model for total number of people in the US Labor force.
The total number of people in the US Labor force = Number of Men + Number of Women in US Labor force.
Adding equation (i) and (ii) we get ,
T = (0.0016t² + 0.315t + 19.467) + (0.007t² - 0.228t + 5.908)
Adding the like terms we get ,
T = (0.0016-0.007)t² + (0.315-0.228)t + (19.467-5.908)
T = -0.0054t² + 0.087t + 13.559
Therefore , the total number of people in the US Labor force is modeled by the equation T = -0.0054t² + 0.087t + 13.559 .

A bin of 50 manufactured parts contains 3 defective parts and 47 nondefective parts. two parts are selected randomly without replacement. let a denote the event that the first part is defective. let b be the event that the second part. is defective. find the p(b)
The probability that the event that the second part is defective will be 0.0564.
How to calculate the probability?From the information, the bin of 50 manufactured parts contains 3 defective parts and 47 nondefective
Therefore, the probability of having a defective and non defective parts will be:
= 47/50 × 3/50
= 0.94 × 0.06
= 0.0564
Therefore, the probability that the event that the second part is defective will be 0.0564.
