Here is the first one
A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)

Answer:
A. (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)
B. is a function
C. is a function
Step-by-step explanation:
Both relations are functions.
A relation is NOT a function if the same input value maps to two different output values. Virtually any relation involving time as an input will be single-valued: a measure can only have one value at any given time (ignoring quantum physics).
__
A: If height decreases 1/2 inch per hour, then some ordered pairs could be ...
(hours, inches) = (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)
For each additional hour, 0.5 inches was subtracted from height.
__
B: There is only one output for each input, so the relation is a function.
__
C: Yes, the relation is still a function. There is still only one output value for each input value.

A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)
Answers
Answer:
79.9 units
Step-by-step explanation:
Hi there,
Before solving this problem, it is important to know the formula:
D = [tex]\frac{m}{v}[/tex].
D = density
m = mass
v = volume
Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.
D = [tex]\frac{799}{10}[/tex]
D = 79.9
Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.
Cheers.
Find the value of x and find whether the angles or supplementary or complementary.
Answers
Answer:
1) x = 31
2) Both angles add up to be a supplementary angle (an angle who's sum is 180° altogether).
Step-by-step explanation:
1) Since both angles add up to be a supplementary,
→ equation 1 + equation 2 = 180
→ (3x + 25) + (2x) = 180
Solving by applying algebra will give the answer "x = 31".

Here is Laila’s graph from the previous screen.
Write your own equation in the form y=mx+b that could represent Laila’s graph.
Answers
Answer:
y=-1/3x+8
Step-by-step explanation:
There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.

Which space mission from Earth traveled to the moon at a faster pace, Apollo 11 or Luna I?
Apollo 11 - 8.35 * 10^1 kilometers/minute
Luna l - 1.76 * 10^2 kilometers/minute
Answers
Answer:
Apollo 11 - 8.35 * 10^1 kilometers/minute
Step-by-step explanation:
The primary objective of Apollo 11 was to complete a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return to Earth.
Additional flight objectives included scientific exploration by the lunar module, or LM, crew; deployment of a television camera to transmit signals to Earth; and deployment of a solar wind composition experiment, seismic experiment package and a Laser Ranging Retroreflector. During the exploration, the two astronauts were to gather samples of lunar-surface materials for return to Earth. They also were to extensively photograph the lunar terrain, the deployed scientific equipment, the LM spacecraft, and each other, both with still and motion picture cameras. This was to be the last Apollo mission to fly a "free-return" trajectory, which would enable a return to Earth with no engine firing, providing a ready abort of the mission at any time prior to lunar orbit insertion.
Answer:
The average speed of Luna I was 1.76 x 10^2 kilometers/minutes. The average speed of Apollo 11 was 8.35 x 10^1.
The average speed of Luna I was greater than the average speed of Apollo 11. So, Luna I traveled at a faster pace than Apollo 11.

Jack and his friends are going hiking next week. There are four trails they can hike: Grayson Pass, Giant’s Ridge, Three Summits, and Elderberry. To make a decision, they use a spinner divided into four colors. They spin it 60 times to check the fairness of their model and record the results in this table.
The relative frequency of the spinner landing on green is
The relative frequency of the spinner landing on blue is
The relative frequency of the spinner landing on yellow is
The relative frequency of the spinner landing on red is
Answers
Answer:
Step-by-step explanation:
The theoretical frequency would be 1/4, and if spun 60 times, 15/60.
The relative frequency is how many times it actually landed on each color.
So green is 6/60
Blue is 24/60
Yellow is 9/60
Red is 21/60
I don't know if they want these in their simplest form (sometimes the test says one way or the other), but here they are, reduced:
Green: 1/10
Blue: 4/10
Yellow: 3/20
Red: 7/20

#1 - HINT - you are finding the total amount make sure you add the interest you calculate to the original deposit amount
Answers
Answer:
$292.50
Step-by-step explanation:
Equation - A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 2.5%/100 = 0.025 per year.
Solving our equation:
A = 260(1 + (0.025 × 5)) = 292.5
A = $292.50
The total amount accrued, principal plus interest, from simple interest on a principal of $260.00 at a rate of 2.5% per year for 5 years is $292.50.
