Step-by-step explanation:
Here is a weight conversion problem.
In this question, we shall be making conversions from grams to pounds.
Kindly note that 453.592 grams = 1 pound as stated in the question
a. 800 grams
Kindly recall;
453.592 grams = 1 pound
800 grams = x pound
Thus;
453.592 * x = 800 * 1
x = 800/453.592
x = 1.764 pounds which is 1.76 pounds to 2 decimal places
b. 700 grams
1 pound = 453.592 grams
y pound = 700 grams
y * 453.592 = 700 * 1
y = 700/453.592
y = 1.543 pounds which is 1.54 to 2 decimal places

)A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 50%. The probability of the arrow landing on a section colored blue is 10%. What is the probability of the arrow landing on a section colored green? I need help
Answer:
40%
Step-by-step explanation:
The probability of the arrow landing on the green section is a 40% chance
This is because there are only 3 sections where one is 50 and the other is 10
To find the green we can create an equation, where x = green section
50 + 10 + x = 100
The equation equals 100 because that's the highest the percentage will go in probability, unless we were told otherwise
60 + x = 100
x = 100 - 60
x = 40

a child's toy train collection contains 5 engines, 5 red cars, 7 blue cars, and 2 cabooses. What is the probability of randomly selecting pieces to make a three-part train of engine, red car, caboose?
Answer:
25/2907Step-by-step explanation:
Probability = Expected outcome/Total outcome of events
If a child's toy train collection contains 5 engines, 5 red cars, 7 blue cars, and 2 cabooses, the total collection will be 5+5+7+2 = 19 total collection
Note that if we are choosing this parts to make part engine, his car parts will no longer be replaced. Hence this is a problem of probability without replacement
If we randomly select pieces to make a three-part train of engine, red car and caboose, this can be chosen in that order and the following ways;
Probability of choosing an engine = 5/19
Probability of choosing a red car = 5/18 (note that the total collection has reduced by 1 since we didn't replace the engine)
Probability of choosing a carboose= 2/17 (the car chosen was not replaced as well)
Therefore the probability of randomly selecting pieces to make a three-part train of engine, red car, caboose is the product of the three probability calculated above i.e 5/19 * 5/18 * 2/17 = 50/5814
= 25/2907

Step 2: Distribute negative
58 - x - x = 12
Step 3: Combine like terms
58 - 2x = 12
Step 4: Subtract 58 on both sides
-2x = -46
Step 5: Isolate x (divide both sides by -2)
x = 23

Then, AC = 5x - 8 + 16 - 3x
AC = 2x + 8
3. AC = 3x - 1, BC = 12-x
Then, AB =( 3x -1 ) - ( 12 - x )
AB = 2x - 13
4. AB = 2x + 11, BC = 4x - 5
Then, AC = 2x + 11 + 4x - 5
AC = 6x + 6
5. AC = 6x-4, BC = 4x - 3

Two airplanes leave the airport. Plane A departs at a 41° angle from the runway, and plane B departs at a 43° from the runway. Which plane was farther away from the airport when it was 5 miles from the ground? Round the solutions to the nearest hundredth.
Plane A / 7.62 mi away
Plane A / 6.63 mi away
Plane B / 6.84 mi away
Plane B / 7.33 mi away
Answer:
Plane A / 7.62 mi away
Step-by-step explanation:
We have to calculate the distance of each plane from the airport.
In other to do this, we would use the trigonometric function of Sine
sin θ = Opposite/Hypotenuse
For Plane A
Plane A departs at a 41° angle from the runway
sin θ = Opposite/Hypotenuse
θ = 41°
Distance from the ground = Opposite = 5 miles
Hypotenuse = ???
sin 41° = 5 miles/Hypotenuse
sin 41° × Hypotenuse = 5 miles
Hypotenuse = 5 miles/sin 41°
Hypotenuse = 7.6212654335 miles
Approximately to the nearest hundredth ≈ 7.62 miles
For Plane B
Plane B departs at a 43° from the runway
sin θ = Opposite/Hypotenuse
θ = 43°
Distance from the ground = Opposite = 5 miles
Hypotenuse = ???
sin 43° = 5 miles/Hypotenuse
sin 43° × Hypotenuse = 5 miles
Hypotenuse = 5 miles/sin 43°
Hypotenuse = 7.3313959282 miles
Approximately to the nearest hundredth ≈ 7.33 miles
From the above calculation, we can see that Plane A what 7.62 miles away from the airport while Plane b was 7.33 miles away from the airport.
Therefore Plane A was farther away from the airport (7.62 miles away) when it was 5 miles from the ground.

A thread is wound 200 times round a reel of diameter 5cm. Use the value 3 for pie to find the approximate length of the thread in metres.
Answer:
L = 30 m
Step-by-step explanation:
lets make it simple and accurate
given
reel dia = 5 cm = 0.05 m
200 times round the reel
π = 3
reel O circumference = π d
Length of thread = Number of times round the reel x circumference
therefore,
L = 200 x (3 * 0.05)
L = 30 m
The approximate length of the thread wound around the reel is 30 meters.
Here, we have,
To find the approximate length of the thread wound around the reel, we can use the formula for the circumference of a circle.
Circumference = π * diameter
Given that
the diameter of the reel is 5 cm and we are using the value 3 for π, we can calculate the circumference:
Circumference = 3 * 5 cm
Circumference = 15 cm
Now, since the thread is wound 200 times around the reel, we need to calculate the total length of the thread:
Total length of thread = Circumference * Number of times wound
Total length of thread = 15 cm * 200
Total length of thread = 3000 cm
To convert the length from centimeters to meters, we divide by 100:
Total length of thread in meters = 3000 cm / 100
Total length of thread in meters = 30 meters
Therefore, the approximate length of the thread wound around the reel is 30 meters.

You estimate that the driving distance from Raleigh, NC to Charlotte, NC is around 180 miles. When you looked it up on the internet, you found that the actual distance is only 167.5 miles. What was the relative (percent) error of your estimate? In other words, how far off were you from the actual value?
Answer:
i. The relative error in the estimated distance is approximately 7.5%.
ii. The value of the estimated distance was about 12.5 miles far of from the actual value.
Step-by-step explanation:
Given that;
Estimated distance ≅ 180 miles
Actual distance = 167.5 miles
Then,
Estimated distance - Actual distance = 180 - 167.5
= 12.5 miles
So that,
Relative error = [tex](\frac{estimated distance - actual distance}{actual distance} )[/tex] × 100%
= [tex]\frac{12.5}{167.5}[/tex] × 100%
= 0.07463 × 100%
= 7.5%
i. The relative error in the estimated distance is approximately 7.5%.
ii. The value of the estimated distance was about 12.5 miles far of from the actual value.
4. Describe how you can tell by looking at the graph of a function
which variable is the input variable and which is the output variable.
Answer: The variable in the vertical axis (or y-axis) is the output
The variable in the horizontal axis (or x-axis) is the input.
Step-by-step explanation:
Usually, a graph of a function y = f(x) is represented in an X-Y coordinate axis.
An X-Y coordinate axis is conformed by two perpendicular lines, one vertical (y-axis) and one horizontal (x-axis)
The vertical axis (or the y-axis) is the output, and the horizontal axis (or the x-axis) is the input.
This method will work almost always, as is standardized that the x-axis corresponds to the input, and the y-axis corresponds to the output.
