b) 2:1:5
c) 2:1:48
d) 15:24:32
2) 56:12:3
Step-by-step explanation:
Untuk membentuk nisbah tiga kuantiti, pertama-tama kita menukar masing-masing menjadi unit yang sama.
a) 2 minggu hingga 16 hari hingga 1 minggu
Menukar semuanya menjadi bilangan hari, kerana ia sangat setanding.
2 minggu = 14 hari
16 hari = 16 hari
1 minggu = 7 hari
2 minggu hingga 16 hari hingga 1 minggu = 14 hari hingga 16 hari hingga 7 hari
14: 16: 7
b) 0.1 kg hingga 50 g hingga 0.25 kg
Menukar semua menjadi gram
= 100 g hingga 50 g hingga 250 g
= 100: 50: 250
Bahagikan dengan 50
= 2 : 1 : 5
c) 4 minit hingga 120 saat hingga 1.6 jam
Menukar semua menjadi beberapa saat
= 240 saat hingga 120 saat hingga (1.6 × 60 × 60) saat
= 240 saat hingga 120 saat hingga 5,760 saat
= 2: 1: 48
d) 3 m hingga 480 cm hingga 6 400 mm
Menukar semua ini menjadi mm
= 3000 mm hingga 4800 mm hingga 6400 mm
Membahagi hingga 200 mm
= 15:24:32
2) RM5.60 hingga RM1.20 hingga 30 sen
Menukar semuanya kepada sen
= 560 sen hingga 120 sen hingga 30 sen
Membahagi hingga 10
= 56: 12: 3
Semoga ini Membantu !!!

2. Tahir pays RM5.60 for a plate of beriani rice, RM1.20 for a glass of tea and 30 cents for a piece of cake.
Represent the price relationship for beriani rice, tea and cake in the form of a: b: c.
Solution
To form a ratio of three quantities, we first convert each of them to the same units.
a) 2 weeks to 16 days to 1 week
Converting all of it to number of days, as itnis very comparable.
2 weeks = 14 days
16 days = 16 days
1 week = 7 days
2 weeks to 16 days to 1 week
= 14 days to 16 days to 7 days
14 : 16 : 7
b) 0.1 kg to 50 g to 0.25 kg
Converting all into grams
= 100 g to 50 g to 250 g
= 100 : 50 : 250
Divide through by 50
= 2 : 1 : 5
(c) 4 minutes to 120 seconds to 1.6 hours
Converting all into seconds
= 240 seconds to 120 seconds to (1.6×60×60) seconds
= 240 seconds to 120 seconds to 5,760 seconds
= 2:1:48
(d) 3 m to 480 cm to 6 400 mm
Converting all of this to mm
= 3000 mm to 4800 mm to 6400 mm
Dividing through by 200 mm
= 15:24:32
2) RM5.60 to RM1.20 to 30 cents
Converting it all to cents
= 560 cents to 120 cents to 30 cents
Dividing through by 10
= 56:12:3

The advisor of a school club wants to select 4 of its 25 members to raise and lower the flag each day this week. She assigns a two-digit number from 01 to 25 to each student. What are the numbers that correspond to the members who will raise and lower the flag? Use the random number table below.
97836 74547 79986 58820 36071 17996 59066 36220 46340 66069 51761 41740 39326 52760
The numbers that correspond to the students are (Use a comma to separate answers as needed.)
The numbers that correspond to the members who will raise and lower the flag are 97836, 74547, 79986, and 58820.
To select 4 members from a group of 25, we can use the random number table provided to assign numbers to each student and choose the corresponding numbers to identify the members who will raise and lower the flag. Let's go through the process step by step:
Step 1: Assign a two-digit number from 01 to 25 to each student.
We have 25 students, so we can assign each student a number from 01 to 25. Let's match the given numbers with the students:
97836 - Student 1
74547 - Student 2
79986 - Student 3
58820 - Student 4
36071 - Student 5
17996 - Student 6
59066 - Student 7
36220 - Student 8
46340 - Student 9
66069 - Student 10
51761 - Student 11
41740 - Student 12
39326 - Student 13
52760 - Student 14
Note: The remaining students from 15 to 25 are not provided in the given random number table, so we cannot assign numbers to them based on the given information.
Step 2: Choose the corresponding numbers to identify the members who will raise and lower the flag.
Since we need 4 members, we can select any four numbers from the given list that correspond to the assigned numbers of the students. Let's say we choose the first four numbers:
97836 - Student 1 (Will raise and lower the flag)
74547 - Student 2 (Will raise and lower the flag)
79986 - Student 3 (Will raise and lower the flag)
58820 - Student 4 (Will raise and lower the flag)

if you toss a die once, consider the two events , you get a 5 OR 6. YOU GET AT MOST 3. are these events independent, explain WHY OR WHY NOT
Answer: These events are independent.
Step-by-step explanation:
Two events are considered independent if the outcome of one event does not affect the outcome of the other event. In this case, getting a 5 or 6 on a dice toss and getting at most 3 on a dice toss are independent events.
This is because the probability of getting a 5 or 6 is 2/6 or 1/3, which is completely unrelated to the probability of getting at most 3, which is 3/6 or 1/2. The outcome of getting a 5 or 6 does not affect the probability of getting at most 3, and vice versa. Therefore, these events are independent.

5x+y=7
20x+2=y
The solution of given system of equations is (1/5, 6).
What is system of equation?
A set or group of equations that you solve all at once is referred to as a "system" of equations. The simplest linear system is one with two equations and two variables. Linear equations are simpler than non-linear equations because they graph as straight lines.
Given equations : 5x+y=7
20x+2=y
We can solve it by using substitution method:
Now, we have 5x+y=7
it can be written as,
y = 7 - 5x .... equation 1
Similarly, we have 20x+2=y
can be written as,
y = 20x+2 ..... equation 2
Subtracting equation 1 from equation 2
we get, 20x+2 - ( 7 - 5x ) = 0
20x + 5x + 2 - 7 = 0
25x = 5
x = 1/5
Putting x=1/5 in equation 1,
we get, y = 20 × 1/5 + 2

On March 24, 1989, the Exxon Valdez oil tanker ran aground and leaked millions of gallons of oil into Prince William Sound. The spill covered approximately 11,000 square miles of ocean. The oil spread out in a circular pattern and the radius increased by 0.10 mph. Use π = 3.14. At this rate, how many hours did it take for oil to cover the area?
Answer:
592 hours
Step-by-step explanation:
Given
\(Area = 11000m^2\)
\(Radius = 0.10m/h\)
Required
Determine the time taken to cover the area
Since, the oil formed a circular pattern; the question will be answered using area of a circle
\(Area = \pi r^2\)
Let t represent the time take to cover 11000m²;
The relationship between these parameters is:
\(11000 = \pi * (0.10t)^2\)
Substitute 3.14 for π
\(11000 = 3.14 * (0.10t)^2\)
Divide both sides by 3.14
\(\frac{11000}{3.14} = \frac{3.14 * (0.10t)^2}{3.14}\)
\(\frac{11000}{3.14} =(0.10t)^2\)
\(3503.18471338 = (0.10t)^2\)
Take square root of both sides
\(\sqrt{3503.18471338} = \sqrt{(0.10t)^2}\)
\(\sqrt{3503.18471338} = 0.10t\)
\(59.1877074516 = 0.10t\)
Divide both sides by 0.10
\(\frac{59.1877074516}{0.10} = \frac{0.10t}{0.10}\)
\(\frac{59.1877074516}{0.10} = t\)
\(591.877074516 = t\)
\(t = 591.877074516\)
\(t = 592\ hours\) (Approximated)
Hence, it'll take approximately 592 hours to cover the given area

Law of Cosines: c² = a² + b² - 2ab-cosC
Measure of Angle C
Answer:
29.4°
Step-by-step explanation:
The equation can be rearranged to give C directly.
C = arccos((a^2 +b^2 -c^2)/(2ab))
C = arccos((90^2 +55^2 -50^2)/(2·90·55))
C = arccos(8625/9900) ≈ 29.4002°
C ≈ 29.4°
The measure of angle C is approximately 29.46 degrees.
How to determine angle CTo find the measure of angle C (cos(C)) using the given values a = 55, b = 90, and c = 50, we can use the Cosine Rule formula:
cos(C) = (a² + b² - c²) / (2 * a * b)
Substitute the given values:
cos(C) = (55² + 90² - 50²) / (2 * 55 * 90)
Now, calculate the numerator:
cos(C) = (3025 + 8100 - 2500) / (2 * 55 * 90)
cos(C) = 8625 / 9900
Now, divide to get the final value of cos(C):
cos(C) ≈ 0.8707
To find the measure of angle C itself, we can take the inverse cosine (arccos) of this value:
C ≈ arccos(0.8707)
Using a calculator, you'll find:
C ≈ 29.46 degrees (rounded to two decimal places)
So, the measure of angle C is approximately 29.46 degrees.

A straw is placed inside a rectangular box that is 3 inches by 7 inches by 6 inches, as shown. If the straw fits exactly into the box diagonally from the bottom left corner to the top right back corner, how long is the straw? Leave your answer in simplest radical form.
Answer:
3sqrt(5)
Step-by-step explanation:
We can use the Pythagorean theorem to find the length of the diagonal of the rectangular box.
The Pythagorean theorem states that for a right triangle with legs of length a and b and hypotenuse of length c, we have:
c^2 = a^2 + b^2
In this case, the legs of the right triangle are 3 inches and 6 inches, and the hypotenuse is the length of the straw. So we have:
straw length^2 = 3^2 + 6^2 straw length^2 = 9 + 36 straw length^2 = 45
Taking the square root of both sides, we get:
straw length = sqrt(45) = sqrt(9*5) = sqrt(9)*sqrt(5) = 3sqrt(5)
Therefore, the length of the straw is 3sqrt(5) inches.

The height of a rectangular box is 7 ft. The length is 1 ft longer than thrice the width x. The volume is 798 ft³.
(a) Write an equation in terms of x that represents the given relationship.
The equation is
The equation in terms of x that represents the given relationship is 114 = (1 + 3x) * (Width)
Let's break down the information given:
Height of the rectangular box = 7 ft
Length of the rectangular box = 1 ft longer than thrice the width (x)
Volume of the rectangular box = 798 ft³
To write an equation that represents the given relationship, we need to relate the length, width, and height to the volume.
The volume of a rectangular box is given by the formula: Volume = Length * Width * Height.
Given that the height is 7 ft, we can substitute this value into the equation.
Volume = (Length) * (Width) * (7)
Now, let's focus on the length. It is described as 1 ft longer than thrice the width.
Length = 1 + (3x)
Substituting this value into the equation, we have:
Volume = (1 + (3x)) * (Width) * (7)
Since the volume is given as 798 ft³, we can set up the equation as follows:
798 = (1 + (3x)) * (Width) * 7
Simplifying further, we get:
798 = 7 * (1 + 3x) * (Width)
Dividing both sides of the equation by 7, we have:
114 = (1 + 3x) * (Width)
Therefore, the equation in terms of x that represents the given relationship is:
114 = (1 + 3x) * (Width)
