The rectangular block of wax can make approximately 2 candles.
How do we determine the number of candles that could be made by that block of wax?To calculate the number of candles, we use the formula
V of wax = l x w x h = 10 cm x 9 cm x 20 cm = 1800 cubic cm
V of candle = l x w x h = 9 cm x 9 cm x 12 cm = 972 cubic cm
1800 / 972 = 1.85
The above answer is based on the full question below;
you are melting a rectangular block of wax to make candles. how many candles of the given shape can be made using a block that measures 10 cm by 9cm by 20 cm.
The height of the candle is 12cm and the base width is 9cm

The contradicting statement is
B. I and III
How to know the contradictory statementThe contradictory statement is that of I and III since the sum of angles in a triangle is always 180 degrees.
Given that
I. triangle ABC is a right triangle. say angle C = 90 degrees and
angle B = 103 degrees,
So the sum of the angles in the triangle would be:
= angle B + m angle C

Alejandro is learning how to play guitar. One day out of the week, he attends a 45-minute lesson. The remaining days of the week, he practices guitar for 25 minutes per day. What total number of minutes does Alejandro spend at his lesson and practicing in 3 weeks?
Answer:
3 x 195 = 585 minutes
Step-by-step explanation:
In one week, Alejandro attends a 45-minute lesson and practices for (6 x 25) = 150 minutes (assuming a 7-day week). So, the total number of minutes that Alejandro spends on his guitar in one week is:
45 + 150 = 195 minutes
In 3 weeks, the total number of minutes that Alejandro spends on his guitar is:
3 x 195 = 585 minutes
Therefore, Alejandro spends 585 minutes on his guitar in 3 weeks, including attending a 45-minute lesson once a week and practicing for 25 minutes on the remaining days of the week.

Consider the time taken to completion time (in months) for the construction of a particular model of homes: 4.1 3.2 2.8 2.6 3.7 3.1 9.4 2.5 3.5 3.8 Find the mean, median mode, first quartile and third quartile. Find the outlier?
ChatGPT
To find the mean, we add up all the values and divide by the number of values:
Mean = (4.1 + 3.2 + 2.8 + 2.6 + 3.7 + 3.1 + 9.4 + 2.5 + 3.5 + 3.8) / 10
Mean = 36.7 / 10
Mean = 3.67
To find the median, we need to put the values in order:
2.5, 2.6, 2.8, 3.1, 3.2, 3.5, 3.7, 3.8, 4.1, 9.4
The middle number is the median, which is 3.35 in this case.
To find the mode, we look for the value that appears most often. In this case, there is no mode as no value appears more than once.
To find the first quartile (Q1), we need to find the value that separates the bottom 25% of the data from the top 75%. We can do this by finding the median of the lower half of the data:
2.5, 2.6, 2.8, 3.1, 3.2
The median of this lower half is 2.8, so Q1 = 2.8.
To find the third quartile (Q3), we need to find the value that separates the bottom 75% of the data from the top 25%. We can do this by finding the median of the upper half of the data:
3.7, 3.8, 4.1, 9.4
The median of this upper half is 3.95, so Q3 = 3.95.
To find the outlier, we can use the rule that any value more than 1.5 times the interquartile range (IQR) away from the nearest quartile is considered an outlier. The IQR is the difference between Q3 and Q1:
IQR = Q3 - Q1
IQR = 3.95 - 2.8
IQR = 1.15
1.5 times the IQR is 1.5 * 1.15 = 1.725.
The only value that is more than 1.725 away from either Q1 or Q3 is 9.4. Therefore, 9.4 is the outlier in this data set.
We can use trigonometry to solve this problem. Let h be the height of the building, and let d be the distance from the base of the building to the point where the angle of elevation is measured. Then we have:
tan(18 degrees) = h / d
Solving for h, we get:
h = d * tan(18 degrees)
Substituting d = 510 feet and using a calculator to evaluate the tangent of 18 degrees, we get:
h = 510 feet * tan(18 degrees)
h ≈ 157.3 feet
Rounding this to the nearest whole number, we get that the height of the building is approximately 157 feet.

How can you describe its content and style in Words of the Devil, by Parau na te Varua ino, that was painted in 1892. ??
Answer:
Words of the Devil, by Parau na te Varua ino, is a painting that was created in 1892 in French Polynesia. The painting depicts a scene from Tahitian mythology, in which the goddess Hina is visited by the devil, who is represented as a horned figure with a large, forked tongue. The painting is rich in detail and vivid color, with the figures depicted in bright, bold colors that stand out against the darker background.
The style of the painting is characteristic of the Tahitian art of the time, which was heavily influenced by the traditional Polynesian art forms of carving, tattooing, and tapa cloth decoration. The figures in the painting are depicted in a stylized, almost abstract way, with exaggerated features and bold, sweeping lines. The use of bright colors and bold brushstrokes gives the painting a dynamic, almost chaotic energy that reflects the intense emotions of the scene.
Overall, Words of the Devil is a powerful and striking work of art that captures the mythology and cultural traditions of French Polynesia in the late 19th century.

If someone wants to call Havana, Cuba from the United States, begins with US three digit exit code 011 followed by the two digit country code for Cuba which is 53, followed by the country code of Havana which is 7 and finally by seven-digit local telephone numbers. But this seven-digit local telephone number cannot begin with 0. How many different telephone numbers are possible?
There are possible 4,782,969 different telephone numbers.
We will multiply the number of options for each digit to calculate the total number of possible telephone numbers,.
How to calculate the total number of possible telephone numbers?Using the multiplication principle to estimate the number of possible telephone numbers for each digit:
n1 x n2 x n3 x ... x nk
Here:
the first three digits are fixed: 011
The 4th digit (the first digit of the local phone number) can be any digit from 1 - 9 (i.e. 9 options).
The remaining 6 digits (the second to seventh digit of the local phone number) can be any digit from 0 to 9, except 0 (9 options for each digit).
Therefore, the total number of possible telephone numbers:
9 x 9 x 9 x 9 x 9 x 9 x 9 = 4,782,969,
Therefore, 4,782,969 different telephone numbers are possible.

A wrestler weighs in on the first day at 162 pounds. To make weight for the first match, the wrestler must lose 1.1 pounds per week. This can be modeled by the equation y=−1.1x+162. Use this model to predict the wrestler’s weight at the first match that is 9 weeks away.
The wrestler's weight at the first match will be 152.1 pounds. The solution has been obtained by using the substitution method.
What is the substitution method?
The substitution method is a strategy used in algebra to solve simultaneous linear equations. In this process, as the name suggests, the value of one variable from one equation is swapped in the second equation.
We are given that the given situation can be modeled by the equation
y = −1.1x + 162.
Now, we need to find weight at the first match which is 9 weeks away.
So, we get that x = 9.
By substituting this value in the equation, we get
⇒ y = -1.1 (9) + 162
⇒ y = -9.9 + 162
⇒ y = 152.1
Hence, the wrestler's weight at the first match will be 152.1 pounds.

#CMIIWTo the nearest ten dollars, what can Carlos expect the value of the computer to be 3 years after purchase
Carlos can expect the value of the computer to be $580 three years after purchase.
To model the value of the computer, we can use the formula:
y = abˣ
We know that the initial value of the computer is $1,350, so a = 1350.
We also know that one year after purchase, the value of the computer is $810, so we can use this to find the value of b:
810 = 1350b
b= 0.6
b = 0.6
So our exponential equation is:
y = 1350(0.6)ˣ
To find the value of the computer 3 years after purchase, we can substitute x = 3:
y = 1350(0.6)³
y = 583
Hence, Carlos can expect the value of the computer to be $580 three years after purchase.

The shortest path from vertex A to vertex L in the given diagram is ABDGJLKFI, with a total length of 89.
We can find the length of the shortest path from vertex A to vertex L by calculating the sum of the shortest paths from A to C to F to I to L.
Using Dijkstra's algorithm, we can find the shortest path from A to C, then from C to F, then from F to I, and finally from I to L.
The shortest path from A to C is AB + BC = 3 + 16 = 19. The shortest path from C to F is CF = 25. The shortest path from F to I is FI = 21. The shortest path from I to L is IL = 24.
