Perform the following food service calculation.
Meat served: chicken with a bone
Pounds of chicken available: 48 lbs.
How many guests can be served?
Answers
The number of guests that can be served is 12
How to determine the number of guests?From the question, we have the following parameters that can be used in our computation:
Meat served: 4 lbs chicken with a bone
Pounds of meat available: 48 lbs.
The number of guests needed is calculated using the following equation
Number of guests = Pounds of meat available/Meat served
Substitute the known values in the above equation, so, we have the following representation
Number of guests = 48/4
Evaluate the quotient
Number of guests = 12
Hence, 12 guests can be served with the available meat

A real estate licensee leased a building for 10 years at an annual rent of$48,000. she will receive a commission of 7.5 % for the first 5 years, 5% for the next there years and 3.5% for the final two years. what will her income be from this commission over the life of the lease?
Answers
We have the lease of a building is for 10 years with an annual rent of $48 000.
We first determine the 7.5% for the first 5 years, for that we add the cost of the rent for 5 years, that is:
[tex]5(48000)=240000[/tex]In 5 years the rent will be of $240 000, now we find the 7.5%:
[tex]c_5=\frac{240000\cdot7.5}{100}\Rightarrow c_5=18000[/tex]Her commision for the first 5 years is going to be of $18 000.
Now we determine the 5% for the next 3 years, for this we determine the rent for 3 years:
[tex]3(48000)=144000[/tex]The rent for 3 years adds $144 000, now we determine the 5%:
[tex]c_3=\frac{144000\cdot5}{100}\Rightarrow c_3=7200[/tex]From this we have that the commission for the next 3 years will be of $7200.
And finally, we determine the rent for the two remaining years:
[tex]2(48000)=96000[/tex]We have that the last two years the rent will be of $96000, now we determine the 3.5% of her commission during that time:
[tex]c_2=\frac{96000\cdot3.5}{100}\Rightarrow c_2=3360[/tex]From this we have her commission for the last two years will be of $3360.
Finally we add all of the values of the commissions she will get:
[tex]c_t=18000+7200+3360\Rightarrow c_t=28560[/tex]From this we have that the total commision money she will be getting during those 10 years will be $28 560.
a stationary shop had an equal number of pens and notepads at first. after selling 1250 pens and 380 notepads, there were 4 times as many notepads as pens left. how many pens did the stationary shop have at first
Answers
The stationary shop had 90 pens with them initially.
Let,
The number of pens initially at the stationary shop=x
The number of pens and the number of notepads are said to be equal. Therefore, The number of notepads initially at the stationary shop=x
After selling,
The number of pens = x-1250
The number of notepads = x-380
The number of pens was four times the number of the number of notepads. Modelling the linear equation for the situation:
x-1250=4(x-380)
x-1250=4x-1520
x=4x-270
-3x=-270
x=90
The stationary shop had 90 pens initially.

Suppose S and T are mutually exclusive events. Find P(S or T) if P(S)= 6/11 and P(T)= 1/10

B. 3/55
C. 1/3
D. 71/21
Answers
The value of P(S or T) is 71/110.
What is mutually exclusive event?
If two events cannot happen simultaneously, they are mutually exclusive or discontinuous. The results of a single coin flip, which can result in either heads or tails but not both, serve as an obvious illustration.
As given,
S and T are mutually exclusive events. P(S)= 6/11 , P(T)= 1/10.
By using,
P(S ∪ T) = P(S) + P(T) - P(S ∩ T)
= 6/11 + 1/10 - P(S ∩ T)
= 71/110 - P(A ∩ T)
But the events S and T are mutually exclusive events.
therefore, P(S ∩ T) = 0.
So,
P(S ∪ T) = 71/110
Therefore, value of P(S or T) is 71/110.

The minimum number of tiles will be 122 that Imane needs to cover the floor.
How to Convert Square Feet to Square Inches?Multiply the area by the conversion ratio to convert a square foot measurement to a square inch measurement. Because one square foot equals 144 square inches, you may use the following easy formula to convert:
square inches = square feet × 144
The area in square inches is equal to the square feet multiplied by 144.
The floor she wants to cover has an area of 216 square feet.
The required area in square inches is :
216 × 144 = 31,104 sq in
Each tile covers an area of 256 square inches.
The minimum number of tiles = 31,104 sq in / 256 sq in
The minimum number of tiles = 121.5 ≈ 122
Thus, the minimum number of tiles will be 122 that Imane needs to cover the floor.

Reflection:
A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another. The reflected picture should have the same size and shape as the original, but it faces the opposite way. Changes in position during contemplation may also result in translation. Pre-image and image are terms used to refer to the same thing in this context. ABC and A'B'C are used to represent the pre-image and image, respectively.

Write an equation in point-slope form for the line that has a slope of 1/5 and contains the point (2,−9).
Answers
The equation is y+9=(1/5)(x-2).
What is a slope form?It is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The three major forms of linear equations are point-slope form, standard form, and slope-intercept form. The equation of the slope form is y-y₁ = m(x - x₁)
The formula for the point-slope is,
y-y₁ = m(x - x₁)
y₁ is the y-coordinate of the point in the line, x₁ is the x-coordinate of the point in the line and m is the slope.
y₁ = -9
m = 1/5
x₁ = 2
Substituting the above values in the above equation, we get
y-(-9) = (1/5)(x-2)
By simplifying the above equation, we get
y+9 = (1/5)(x-2)
Therefore, the equation is y + 9 = (1/5)(x-2).

We are asked to find the area of the shaded region.
Notice that the overall figure is a rectangle and the missing area is a triangle.
The area of the rectangle is given by
[tex]A_{\text{rect}}=w\cdot l[/tex]Where w is the width and l is the length of the rectangle.
width = 7 m
length = 16 m
[tex]A_{\text{rect}}=w\cdot l=7\cdot16=112\; \; m^2[/tex]So, the area of the rectangle is 112 m²
The area of the triangle is given by
[tex]A_{\text{tri}}=\frac{1}{2}\cdot b\cdot h[/tex]Where b is the base and h is the height of the triangle.
base = 7 m
height = 8 m
[tex]A_{\text{tri}}=\frac{1}{2}\cdot b\cdot h=\frac{1}{2}\cdot7\cdot8=28\; \; m^2[/tex]So, the area of the triangle is 28 m²
The area of the shaded region can be found by subtracting the area of the triangle from the area of the rectangle.
