Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Step-by-step explanation:
Jaha has designed a rocket. She determines the initial velocity of her rocket is 36 meters per second. She uses the function h(t) = - 9.8t ^ 2 + 36t to find the height, h(t) based on time, t, in seconds. Jana wants to know approximately when her rocket will be at the following heights:
24 Meters
36 Meters
Answers
To find when the rocket will be at a certain height, we can set the equation for height, h(t), equal to the given height and solve for t.
For 24 meters:
-9.8t^2 + 36t = 24
-9.8t^2 + 36t - 24 = 0
We can solve for t using the quadratic formula:
t = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = -9.8, b = 36, and c = -24. Plugging in these values, we get:
t = (-36 ± sqrt(36^2 - 4(-9.8)(-24))) / 2(-9.8)
t ≈ 1.87 seconds or t ≈ 3.14 seconds
So the rocket will be at a height of 24 meters approximately 1.87 seconds after launch and again approximately 3.14 seconds after launch.
For 36 meters:
-9.8t^2 + 36t = 36
-9.8t^2 + 36t - 36 = 0
Using the quadratic formula again, we get:
t = (-36 ± sqrt(36^2 - 4(-9.8)(-36))) / 2(-9.8)
t ≈ 1.16 seconds or t ≈ 3.66 seconds
So the rocket will be at a height of 36 meters approximately 1.16 seconds after launch and again approximately 3.66 seconds after launch.

A right rectangular prism has length 3 1/3 , width 2 1/3 , and height 1 1/3 . You use cubes with fractional edge length 1/3 to find the volume. How many cubes are there for each of the length, width, and height of the prism? Find the volume.
Answers
For the length, we have:
3 1/3 ÷ 1/3 = 10
So there are 10 cubes along the length of the prism.
For the width, we have:
2 1/3 ÷ 1/3 = 7
So there are 7 cubes along the width of the prism.
For the height, we have:
1 1/3 ÷ 1/3 = 4
So there are 4 cubes along the height of the prism.
To find the volume of the prism, we can multiply the number of cubes along each dimension.
Volume = length × width × height
Volume = 10 × 7 × 4
Volume = 280 cubic units
So the volume of the prism is 280 cubic units.

The lengths of two sides of a right angled triangle are 20 cm and 30 cm.
Calculate the length of the third side, if it is:
(a) the hypotenuse
(b) not the hypotenuse
Answers
Answers:
Part (a) 10*sqrt(13) Part (b) 10*sqrt(5)Those values are exact. They approximate to:
10*sqrt(13) = 36.0555
10*sqrt(5) = 22.3607
====================================================
Explanation:
Part (a)
If the unknown third side is the hypotenuse then we need to find the value of c when a = 20 and b = 30.
Apply the pythagorean theorem
a^2 + b^2 = c^2
20^2 + 30^2 = c^2
400 + 900 = c^2
1300 = c^2
c^2 = 1300
c = sqrt(1300)
c = sqrt(100*13)
c = sqrt(100)*sqrt(13)
c = 10*sqrt(13) .... exact length
c = 36.0555 ...... approximate length
------------------------------------
Part (b)
If the third side is not the hypotenuse then that must mean c = 30 is the hypotenuse as this side is larger than the 20 cm side. The hypotenuse is always the longest side.
Let a = 20 be the known leg. Let's find the other unknown leg b using the pythagorean theorem.
a^2 + b^2 = c^2
20^2 + b^2 = 30^2
400 + b^2 = 900
b^2 = 900-400
b^2 = 500
b = sqrt(500)
b = sqrt(100*5)
b = sqrt(100)*sqrt(5)
b = 10*sqrt(5) ..... exact length
b = 22.3607 ....... approximate length

24m+12 is it simplified
Step-by-step explanation:
A
2(12m+6)
12(2m+1)
B
Distributive property
2(12m+6) just has the 2 distributed out of 24m+12
Distributive Property again
12(2m+1) 12 was distributed out of 24m+12
Distributive property a ( b + c ) = a b + a c
C
say M is 2
4(2 + 3 + 5(2)) = 60
2(12(2)+6) = 60 as well (2x12 = 24, 24+6 = 30 times 2 is 60 )
2(12(2)+6) = 60 again (2 times 12 is 24+6 is 30, again 30x2=60 )
Expression 2: 24m+12
Say that m=2 then the original expression would be 4(2+3+10) which is 60
Expression 1 would be 8+12+40 which also equals 60. The only difference between the two expressions is one used the distributive property.
For expression 2, m still equals 2 so it would be 48+12 which also equals 60 and for the this expression you used the distributive property and then addition.

Knowing that the final course grade is determined in the manner described above, Kyra can figure out what grade she needs to earn on the final exam to earn at least a 90% for her final course grade. These are her other grades she has earned so far: Q1 = 92%, Q2 = 85%, Q3 = 88%, Q4 = 84%, and mid-term exam = 89%. What is the least whole percent she must earn on the final exam?
Answers
Answer: Kyra must earn at least 100% on the final exam.
Step-by-step explanation: Kyra's scores have been accumulating from Q1 to Q4 and then the mid term exam. Her scores are outlined as follows;
Q1 = 92, Q2 = 85, Q3 = 88, Q4 = 84, mid-term = 89.
Observe carefully that the data set (number of observed data) is 5.
What she needs now is a final average score of at least 90% after her final exam. She can use this to determine what she needs to score in her final exam. In other words, now that she has a average score, all she needs is a total of all her scores up till her final exam. Note that after writing her final exam, the data set would be six and no longer five.
Before writing her final exam, Kyra's average score was calculated as;
Average = (92 + 85 + 88 + 84 + 89)/5
However after she must have written her final exam, her average would be calculated as;
Average = (92 + 85 + 88 + 84 + 89 + x)/6
Where average is given as 90 and x is the final exam score, you now have
90 = (438 +x)/6
90*6 = 438 + x
540 = 438 + x
Subtract 438 from both sides of the equation
102 = x
Therefore from the results shown, Kyra must score up to 102% in her final exam. However, knowing that she cannot obtain a score higher than 100%, we can conclude that she must score nothing less than 100% (a hundred percent) in her final exam.
How far did I travel to reach my destination on each day of my three-day Trip?

b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
Answers
The total distances you traveled to reach your destination on each day of your three-day trip are as follows:
a) Day 1 = 40 miles
b) Day 2 = 30 miles
c) Day 3 = 11 miles.
How the total distances are determined:The total distances are determined using proportions.
Proportion refers to the fractional value of the whole number or quantity.
a) Day 1:
The fractional distance traveled = ⁵/₈
The remaining distance to travel = 15 miles
15 miles = ³/₈ (1 - ⁵/₈)
Proportionately, the total distance = 40 miles (15 ÷ ³/₈)
b) Day 2:
The distance traveled = 18 miles
The remaining distance to travel = ²/₅
The distance traveled = ³/₅ (1 - ²/₅)
³/₅ = 18 miles
Proportionately, the total distance = 30 miles (18 ÷ ³/₅)
c) Day 3:
The distance traveled = ⁵/₁₁
The distance to travel = 6 miles
The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)
Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Is Figure BBB a scale copy of Figure AAA?
Answers
Reason - if the scale factor of a and b was 2, the dimensions of a would be 4, 7.2 and 10 not the ones present on A
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
Here, we have to determine if Figure B is a scale copy of Figure A, we need to compare the corresponding sides of the two triangles and check if the ratios of their side lengths are equal.
Figure A has side lengths: 3.6, 2, and 5.
Figure B has side lengths: 8.9, 4, and 11.3.
Let's check if the ratios of corresponding side lengths are equal:
Ratio of corresponding side lengths of A and B:
3.6 / 8.9 ≈ 0.4045
2 / 4 = 0.5
5 / 11.3 ≈ 0.4425
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
In order for two triangles to be scale copies of each other, all corresponding side lengths must have the same ratio.
Since the ratios of side lengths in Figure A and Figure B are not equal, they are not scale copies of each other.
