Answer:
The answer would D.) 33.5 because 9.5+24 is 33.5 and since vertical distance is always an absolute value, it will never be a negative number.
The vertical distance between the top and bottom of the boat is calculated by summing the distances above and below the lake's surface, which total 33.5 feet, making option D correct.
To calculate this, we consider that the top deck of the boat is 9.5 feet above the surface of the lake, while the bottom of the boat is 24 feet below the surface. The total vertical distance would be the sum of these two values, as one needs to account for the entire distance the boat covers from top to bottom.
So, the calculation would be as follows: 9.5 feet + 24 feet = 33.5 feet. Therefore, the vertical distance between the top deck and the bottom of the boat is 33.5 feet. This makes option D the correct answer.

-3x-3y=9
3x+8y=6
Answer:
x=-6, y=3
Step-by-step explanation:
I will use elimination to eliminate the x variable.
Add the two equations.
-3x-3y=9
3x+8y=6
-------------------
5y = 15
Divide each side by 5
5y/5 = 15/5
y=3
Now we need to find x
3x+8y=6
Substitute y=3
3x+8*3 =6
3x+24=6
Subtract 24 from each side
3x+24-24 = 6-24
3x = -18
Divide each side by 3
3x/3 = -18/3
x=-6

The ages of Anjali and Aditya are in the ratio 3: 4.Eight years later sum
of their ages will be 44 years. What are their present ages
Answer:
12 years and 16 years
Step-by-step explanation:
their ages are in the ratio 3 : 4
let Anjali = 3x and Aditya = 4x ← present ages
In 8 years then
Anjali = 3x + 8 and Aditya = 4x + 8, hence
3x + 8 + 4x + 8 = 44 ← sum of their ages in 8 years
7x + 16 = 44 ( subtract 16 from both sides )
7x = 28 ( divide both sides by 7 )
x = 4
Anjali is 3x = 3 × 4 = 12 years old and Aditya = 4x = 4 × 4 = 16 years old

Anna, Ivan and Elena are running for class president. On Thursday night Anna had 20% of the votes, Ivan had 35% of the votes and Elena had 45% of the votes. On Friday, final votes were added to the counts and all of them favored Elena. If in the end Anna had 16% of all votes, what percent of the voters chose Ivan?
Answer:
28%
Step-by-step explanation:
On Thursday night Anna had 20% of the votes, Ivan had 35% of the votes and Elena had 45% of the votes. You can take the number of total votes on Thursday equal to 100, then Anna had 20 votes, Ivan had 35 votes and Elena had 45 votes.
Let x be the number of votes added on Friday. All of them favored Elena, then Elena in total had 45+x votes and the number of all votes became 100+x. In the end Anna had 16%, then
100+x - 100%,
20 - 16%.
Write a proportion:
[tex]\dfrac{100+x}{20}=\dfrac{100}{16},\\ \\16(100+x)=2000,\\ \\1600+16x=2000,\\ \\16x=400,\\ \\x=25.[/tex]
Find the percent of the voters that chose Ivan:
125 - 100%,
35 - y%.
Write a proportion:
[tex]\dfrac{125}{35}=\dfrac{100}{y},\\ \\125y=35\cdot 100,\\ \\y=\dfrac{35\cdot 100}{125}=\dfrac{35\cdot 4}{5}=7\cdot 4=28\%.[/tex]

Which basic geometric term has exactly one dimension?
A. Point
B. Plane
C. Line
D. Angle
Answer: Option 'C' is correct.
Step-by-step explanation:
We need to find which has one dimension.
Since Point is undefined term with no size or dimension, but in two dimensional it is found in ordered pair i.e. (x,y)
Plane is also an undefined term with length and width but no thickness, so, it is two dimensional.
Angle is undefined term formed by tow lines or rays diverging from a common vertex, so it is two-dimensional.
But Line is also undefined term with length only but there is no width or thickness.
So, Line has exactly one dimension.
Hence, Option 'C' is correct.

Zoe babysat for x+3 hours yesterday.she earned x-2 dollars per hour.write a polynomial expression that represents the amount Zoe earned
Answer:
y=3x+2
Step-by-step explanation:
The total amount Zoe earned from babysitting is represented by the polynomial expression (x + 3) * (x - 2), which expands to [tex]x^2+x-6[/tex]
Explanation:To find the total amount that Zoe earned, it is necessary to multiply the time she worked by how much she earned per hour. Zoe worked for x + 3 hours yesterday and earned x - 2 dollars per hour. Therefore, the polynomial expression to represent the total amount she earned is (x + 3) * (x - 2). This can be expanded by using the distributive property, to give the polynomial: [tex]x^2[/tex] + x - 6.
So, the amount Zoe earned can be represented by the polynomial expression [tex](x+3)*(x+2)[/tex]

Calculate the difference between the compound interest and simple
interest on ₹20,000 in 2 years at 8% per annum.
Answer: ₹128
Step-by-step explanation:
To work out the simple interest, you need to work out 8% of ₹20,000 for 2 years, which is 1.08 * ₹20,000 = ₹21,600 in the first year and ₹23,200 in the second year
To work out the compound interest, you need to work out 8% of the new value
1st year: ₹21,600
2nd year: 8% of ₹21,600 = ₹23,328
The difference is ₹23,328 - ₹23,200 = ₹128

Jaylan makes limeade using 3/4 cup water for every 1/5 cup of lime juice. Wanchen makes limeade using 2/3 cup of water for every 1/6 cup lime juice. Find the unit rates of water (cups) per lime juice. Whose limeade has a weaker lime flavor? Explain.
Jaylan : Water/Juice=(3/4)/(1/5)=15/4
Wanchen : Water/Juice=(2/3)/(1/6)=4/1 or 16/4
Wanchen has a weaker lime flavor because there is more water in her mixture than Jaylan's limeade. Both have the same amount of lime juice (assuming ratio), and Wanchen has more water, making Wanchen have the limeade that has the weaker lime flavor.

Which set represents a pythagorean triple
A) 1, 2, 3
B) 9, 12, 16
C)30, 40, 50
D)38, 44, 49
Please help!
Answer:
30, 40, 50 which is choice C
Step-by-step explanation:
Square the smaller two values (30 and 40)
30^2 = 900
40^2 = 1600
then add those results
900+1600 = 2500
Notice how 50^2 = 2500 as well. This shows us that 30^2 + 40^2 = 50^2 is a true equation. Both sides lead to the same result 2500. Therefore, a triangle with sides 30, 40, 50 is a right triangle. This is based on the 3-4-5 pythagorean triple, just each side has been multiplied by 10.
The set that represents a Pythagorean triple is 30, 40, 50. Hence, the correct option is C.
Pythagorean triples are sets of three numbers that satisfy the Pythagorean theorem, a² + b² = c², where a, b, and c are the lengths of the sides of a right triangle. To determine which set represents a Pythagorean triple, we need to check if the set's numbers satisfy this theorem.
Looking at the options:
A) 1, 2, 3 does not form a Pythagorean triple.
B) 9, 12, 16 does not form a Pythagorean triple.
C) 30, 40, 50 does form a Pythagorean triple because 30² + 40² = 900 + 1600 = 2500 = 50².
D) 38, 44, 49 does not form a Pythagorean triple.
Therefore, the set that represents a Pythagorean triple is C) 30, 40, 50.
What's the distance between the points (–9,2) and (–4,2)?
Final answer:
The distance between the points (–9,2) and (–4,2) is 5 units, calculated as the absolute difference between the x-coordinates since the y-coordinates are equal.
Explanation:
The distance between the points (–9,2) and (–4,2) can be found using the distance formula, which is derived from the Pythagorean theorem. For two points (x1, y1) and (x2, y2) the distance is given by √((x2 - x1)² + (y2 - y1)²). However, because the y-coordinates of the points are the same, we can simplify this to the absolute value of the difference between the x-coordinates.
In this case, the distance is |(–4) - (–9)|, which simplifies to 5 units. There's no need to calculate a square root because there is no vertical change between the points.

Answer:
A. 0
Step-by-step explanation:
23/40 is approximately 1/2.
11/30 is approximately 1/2.
Sine 1/2 - 1/2 = 0, then 23/40 - 11/30 is approximately 0.
By converting the given fractions to a common denominator and performing subtraction, the result falls closest to the benchmark of 0. Hence, the estimated sum or difference of 23/40 and 11/30 is 0.
Explanation:The given problem is 23/40 - 11/30 and the student has to estimate the result using the benchmarks 0, 1/2, and 1.Steps to resolve the problem:
First, convert both fractions to a common denominator. The smallest number that both 40 and 30 divide into evenly is 120. Therefore, we multiply 23/40 by 3/3 to get 69/120, and 11/30 by 4/4 to get 44/120.Then, subtract the fractions: 69/120 - 44/120 = 25/120.Here, 25/120 is close to 1/4.The benchmark that is closest to 1/4 is 0. So, the estimated sum or difference would be 0.

The Rawlins family has travelled 600 km on their vacation. This has taken them 8 hours. If they continued at the same rate, how long will it take them to complete their journey if the total distance to be travelled is 2100 km?
A. 20 hours
B. 28 hours
C. 26 hours
D. 12 hours
Answer:
B. 28 hours
Step-by-step explanation:
GIVEN :- Time taken by family to travel 600 km is 8 hours
CALCULATIONS :-
To calculate the time to travel 2100 km, we need to calculate distance traveled in 1 hour
Distance traveled in 1 hour = 600 km ÷ 8
= 75 km
Time required to travel 2100 km = 2100 ÷ 75
= 28 hours
Therefore time required to travel 2100 km is 28 hours.
Final answer:
The Rawlins family, traveling at a speed of 75 km/hour, will take a total of 28 hours
Explanation:
To determine the travel time for the remaining distance of the Rawlins family's journey, we use the formula
time = distance / speed. First, we need to find the family's speed during their trip. They have travelled 600 km in 8 hours, so their speed is
600 km / 8 hours = 75 km/hour.
Next, we calculate the time it would take to travel the total distance of 2100 km at this speed. So,
time = 2100 km / 75 km/hour. Upon performing the calculation, we get 28 hours. Therefore, if they continue at the same speed, the total travel time for the entire journey would be 28 hours.
