Answer:
4. 4155.3cm³
5. 783m³
6. 1962.44821094mm³
#4 Explanation:
First, you would separate the 2 shapes it consists of, a cylinder and a cone.
For the cone, you would use the equation (1/3)πr²h. Fill in the appropriate variables with the numbers from the formula. Pi, π, is a number itself so you leave it as it is.
r = radius = 8cm
h = height = 14cm
(1/3)(π)(8)²(14)
Put this equation into a calculator, it's important to include the parentheses or it might give you the incorrect answer, this is so that it separates the different values while multiplying. After inputting it, it should give you:
v = 938.289005872cm³
Then, you would have to find the volume of the cylinder, using the equation; πr²h.
The radius would be the same as the cone, and the height is as the problem states, 16cm.
Solve the problem after inputting the values:
π(8)²(16)= 3216.99087728cm³
Then, add the values to get the total volume.
938.289005872cm³ + 3216.99087728cm³ =
4155.27988315cm³
Round to nearest tenth: 4155.3cm³
#5 Explanation:
Again, you would separate the shapes into 2 separate ones.
The top one is a triangular prism and uses the equation (1/2)bh.
b = base = 9m
h = 12m
(1/2)(9)(12) = 54m³
The bottom shape is a rectangular prism, where we use the equation L×W×H.
Length = 9m
Width = 9m
Height = 9m
Substitute the numbers into the equation.
9×9×9 = 729m³
Add both of them together to get the total volume:
54m³ + 729m³ = 783m³
#6 Equation:
In this figure, we are looking for the outer shape, so we will have to subtract the smaller cone.
First, we find the total volume, and we will use the same equation, (1/3)πr²h.
radius = half of diameter = 20/2 = 10mm
h = 20mm
(1/3)π(10)²(20) = 2094.39510239mm³
Second, we find the volume of the smaller cone, using the same equation, (1/3)πr²h.
In order to find the diameter, we will have to subtract the 7 mm that are on either side of the cone, so 20 - 14 = 6, then divide it by 2 so we can get the necessary radius. 6/2 = 3
r = 3mm
h = 14mm
Substitute values into equation and use calculator to solve.
(1/3)π(3)²(14) = 131.946891451mm³
Subtract the value of the smaller cone from total volume in order to get the volume for this figure.
2094.39510239mm³ - 131.946891451mm³ =
1962.44821094mm³
Ravi has two and one-fourth meters of rope. He gives ninety-three centimeters of the rope to his brother. How many centimeters of rope does Ravi have left?
If he gives ninety-three centimeters of the rope to his brother, Ravi has 132 centimeters of rope left.
Two and one-fourth meters of rope can be written as 2.25 meters. Since 1 meter is equal to 100 centimeters, we can convert 2.25 meters to centimeters by multiplying it by 100, giving us 225 centimeters.
If Ravi gives 93 centimeters of the rope to his brother, we can subtract it from the original length to find how much rope he has left.
225 cm - 93 cm = 132 cm
In general, to convert between meters and centimeters, you can multiply the number of meters by 100 to get the length in centimeters. To convert between centimeters and meters, you can divide the number of centimeters by 100 to get the length in meters.

PS: Its in a Chapter 11 Go math book! Maybe... can you help me pls?
The measure of p in the diagram is,
m∠P = 45°
We have to given that;
PM is perpendicular to MO.
Now, If m ∠P = m∠2
then it's an isosceles triangle.
And, m ∠M = 90°, therefore it's an isosceles right triangle.
We know that,
the sum of measures of angles in a triangle is equal 180°.
Therefore we have the equation:
m∠P + m∠2 + m∠M = 180°
Substitute m∠M = 90° and m∠P = m∠2 = x:
x + x + 90° = 180°
substract 90° from both sides
2x = 90°
divide both sides by 2
x = 45°
m∠P = 45°
Thus, The measure of p in the diagram is,
m∠P = 45°

Question 5 Joy is a 52-year-old nurse who earns a salary of R286 500 per annum. She contributes 7% of her annua salary to a pension fund. She only has her 2 daughters listed as a dependents on her medical aid. Sh is concerned that the R4000 monthly income tax deduction is too much.
Determine Joy's annual income tax liability. If the amount is significantly different from the R4000 monthly deduction, she may need to consult a tax advisor to ensure accurate tax planning.
To assess whether the monthly income tax deduction of R4000 is too much for Joy, we need to calculate her annual income tax liability and compare it to the deduction.
First, let's calculate the amount Joy contributes to her pension fund annually:
Pension fund contribution = 7% of annual salary
Pension fund contribution = 7/100 * R286,500
Pension fund contribution = R20,055
Next, we need to determine Joy's taxable income by subtracting her pension fund contribution from her annual salary:
Taxable income = Annual salary - Pension fund contribution
Taxable income = R286,500 - R20,055
Taxable income = R266,445
Now, we can calculate the income tax liability based on the South African income tax brackets for the 2023 tax year. Please note that tax brackets are subject to change, so it's essential to verify with the latest tax regulations.
According to the current tax brackets, the tax rates for the 2023 tax year are as follows:
18% on the first R216,200 of taxable income
26% on the portion of taxable income between R216,201 and R337,800
31% on the portion of taxable income between R337,801 and R467,500
36% on the portion of taxable income between R467,501 and R613,600
39% on the portion of taxable income above R613,601
Using these tax rates, we can calculate the income tax liability:
Tax liability = (18% * amount within first bracket) + (26% * amount within second bracket) + (31% * amount within third bracket) + (36% * amount within fourth bracket) + (39% * amount within fifth bracket)
First, let's calculate the amounts within each tax bracket:
Amount within first bracket = min(Taxable income, R216,200)
Amount within second bracket = min(max(Taxable income - R216,200, 0), R337,800 - R216,201)
Amount within third bracket = min(max(Taxable income - R337,800, 0), R467,500 - R337,801)
Amount within fourth bracket = min(max(Taxable income - R467,500, 0), R613,600 - R467,501)
Amount within fifth bracket = max(Taxable income - R613,600, 0)
Now, let's substitute the values and calculate the income tax liability:
Tax liability = (18% * min(Taxable income, R216,200)) + (26% * min(max(Taxable income - R216,200, 0), R337,800 - R216,201)) + (31% * min(max(Taxable income - R337,800, 0), R467,500 - R337,801)) + (36% * min(max(Taxable income - R467,500, 0), R613,600 - R467,501)) + (39% * max(Taxable income - R613,600, 0))
By calculating this equation, you can determine Joy's annual income tax liability. If the amount is significantly different from the R4000 monthly deduction, she may need to consult a tax advisor to ensure accurate tax planning.

Answer:
Step-by-step explanation:
To graph the function, we'll break it down into three parts based on the given conditions.
For x ≤ -2:
The function f(x) = x + 6 is valid in this range. We'll plot a straight line with a slope of 1 and a y-intercept of 6. Since x ≤ -2, we'll extend the line towards the left indefinitely.
For -2 ≤ x ≤ 1:
The function f(x) = x² is valid in this range. We'll plot a curve representing a quadratic function. The graph starts at the point (-2, 4), curves upward, and ends at the point (1, 1).
For x > 1:
The function f(x) = -2x is valid in this range. We'll plot a straight line with a negative slope of -2. Since x > 1, we'll extend the line towards the right indefinitely.
Combining these three parts, we get the graph of the function as follows:

What is the length of Arc LM? Use 3.14 as pi and round your answer to the nearest tenth. please show work, will mark brainliest.
To find the length of arc LM, we need to use the formula for the circumference of a circle:
C = 2πr
In this case, the arc LM is a portion of the circumference of the circle. To find the length of the arc, we need to determine the angle at the center of the circle that corresponds to the arc.
Looking at the image you provided, we can see that angle LOM is a right angle (90 degrees). The angle at the center of the circle, LOCM, is half of the right angle, which is 45 degrees.
To calculate the length of arc LM, we need to find the fraction of the total circumference represented by the central angle LOCM. The fraction is given by:
Fraction of circumference = Angle at center / 360 degrees
Fraction of circumference = 45 degrees / 360 degrees
Fraction of circumference = 1/8
Now, we can calculate the length of arc LM:
Length of arc LM = Fraction of circumference * Circumference
Length of arc LM = (1/8) * (2πr)
Since the radius (r) is not given in the image, we cannot calculate the exact length of arc LM. However, we can provide the formula for the length of arc LM in terms of the radius:
Length of arc LM = (1/8) * (2πr) = πr/4
So, the length of arc LM is πr/4, where r is the radius of the circle.
If you have the value of the radius, you can substitute it into the formula to find the specific length of arc LM.

The probability that a random adult has a high school degree or some college, but has no college degree is 53. 50 % .
How to find the probability ?The number of adults with some high school degree or some college would be :
= 3, 561 + 6, 058
= 9, 619 people
The probability that a random adult would have high school degree or some college is therefore :
= Adults with high school degree or some college / Total adults in the town
= 9, 619 / 17, 981
= 53. 50 %
In conclusion, the probability is 53. 50%.

A scale has a percent error of 5%. The actual mass of a rock is 30 g.
The scale is likely to show the mass as either;
A: 25 g. or 30 g.
B: 25.5 g. or 30.5 g.
C: 28 g or 31.5 g.
D: 28.5 g. or 31.5 g.
Answer:
ans d
Step-by-step explanation:
5 percent of 30 is 1.5 so d
Is 34.05 greater than 34.59
No, 34.05 is not greater than 34.59.
When comparing two numbers, we look at their digits from left to right.
In this case, both numbers start with 34, which means they have the same value in the tens place.
However, when we move to the decimal part, 0.05 is smaller than 0.59.
Therefore, 34.05 is smaller than 34.59.

a) Area of rectangle = 28 cm²
b) Area of triangle = 14 cm²
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
Length of rectangle = 4 cm
Width of rectangle = 7 cm
Since, WE know that;
Area of rectangle = Lenght x Width
Hence, We get;
Area of rectangle = 4 x 7
Area of rectangle = 28 cm²
And, By figure,
Heigh of triangle = 4 cm
Base of triangle = 7 cm
Hence,
Area of triangle = 1/2 x 4 x 7
Area of triangle = 14 cm²

Let F be a Boolean function defined by the following Boolean expression:
F = (¬A ∧ ¬B ∧ ¬C ∧ D) ∨ (¬A ∧ B ∧ C ∧ D) ∨ (A ∧ B ∧ ¬C ∧ D) ∨ (A ∧ ¬B ∧ C ∧ D) ∨ (A ∧ ¬B ∧ ¬C ∧ ¬D)
Where A, B, C, and D are Boolean variables.
a) Construct a truth table for F.
b) Find the minimal sum-of-products form of F using Quine-McCluskey method.
c) Using Boolean algebra, simplify the Boolean expression of F and state the simplified Boolean expression in terms of the three variables A, B, and C.
Answer:
a) The truth table for F is as follows:
A B C D F
0 0 0 0 1
0 0 0 1 0
0 0 1 0 0
0 0 1 1 1
0 1 0 0 0
0 1 0 1 1
0 1 1 0 1
0 1 1 1 0

1 0 1 1 0
1 1 0 0 1
1 1 0 1 0
1 1 1 0 0
1 1 1 1 1
b) Using the Quine-McCluskey method, we can find the minimal sum-of-products form of F:
F = ¬A ∧ ¬B ∧ D ∨ ¬A ∧ C ∧ D ∨ A ∧ B ∧ ¬C ∧ D ∨ A ∧ ¬B ∧ C ∧ D
c) Using Boolean algebra, we can simplify the Boolean expression of F as follows:
F = (¬A ∧ ¬B ∧ D) ∨ (¬A ∧ C ∧ D) ∨ (A ∧ B ∧ ¬C ∧ D) ∨ (A ∧ ¬B ∧ C ∧ D)
= (¬A ∧ (¬B ∧ D ∨ C ∧ D)) ∨ (A ∧ (B ∧ ¬C ∧ D ∨ ¬B ∧ C ∧ D))
= (¬A ∧ (¬B ∨ C) ∧ D) ∨ (A ∧ ((B ∧ ¬C) ∨ (¬B ∧ C)) ∧ D)
= (¬A ∧ ¬B ∧ C ∧ D) ∨ (¬A ∧ B ∧ ¬C ∧ D) ∨ (A ∧ B ∧ C ∧ D) ∨ (A ∧ ¬B ∧ ¬C ∧ D)
Therefore, the simplified Boolean expression of F in terms of the three variables A, B, and C is:
F = (¬A ∧ ¬B ∧ C ∧ D) ∨ (¬A ∧ B ∧ ¬C ∧ D) ∨ (A ∧ B ∧ C ∧ D) ∨ (A ∧ ¬B ∧ ¬C ∧ D)
Step-by-step explanation:
BTS-2 has coordinates (-8,6) and the edge connecting vertices P and Q has the equation y = 4.
(b) Write down the coordinates of BTS-4.
a. Jason will receive the strongest signal from BTS-4 because he is located in the Voronoi cell of BTS-4.
b. The coordinates of BTS-4 are (−8,4).
How to explain the informationa. Jason will receive the strongest signal from BTS-4 because he is located in the Voronoi cell of BTS-4. A Voronoi cell is a region of space that is closer to a given point than any other point. In this case, the given point is BTS-4. The Voronoi diagram is a partitioning of the plane into Voronoi cells, one for each point.
b. The edge connecting vertices P and Q has the equation y=4, which means that it is a horizontal line that intersects the y-axis at 4. The coordinates of BTS-2 are (−8,6), which means that it is located 8 units to the left of the origin and 6 units above the origin. Therefore, BTS-4 must be located 8 units to the left of the origin and 4 units above the origin, which gives it the coordinates (−8,4).
