STEAM: The boiling pint of water is affected by changes in elevation. Use the expression of -2A/1000 where a represents the altitude in feet to find the number of degrees Farenhite at which the boiling point of water changes at altitude 5,000 feet
A) -10°F B) 20°F C) 10°F D) -20°F
Answer:
A) -10°F
Step-by-step explanation:
Given that:
Boiling point of water gets affected when there is a change in the elevation.
Expression to represent the temperature i.e. boiling point w.r.to altitude [tex]A[/tex] is given by the equation:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
Given that, the altitude, [tex]A[/tex] = 5,000 feet
To find:
The number of degrees Farenhite at which the boiling point of water will change.
Solution:
Here, we are given the expression:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
And value of altitude, [tex]A[/tex] = 5,000 feet
Let us put the value of [tex]A[/tex] in the equation and let us find the value of temperature in [tex]^\circ F[/tex].
Temperature in [tex]^\circ F[/tex] =
[tex]\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}[/tex]
Therefore, the answer is:
A) -10°F
Which shows the result of a correct substitution for the system y=2x+3 and 3x+2y=9?
Answer:
The result of the correct substitution gives:
x = 3/7 and y = 27/7
Step-by-step explanation:
From the given information:
y = 2x + 3 ---- (1)
3x + 2y = 9 ---- (2)
By using substitutional method
Substitute the value of y = 2x +3 into equation (2)
So,
3x + 2(2x + 3) = 9
3x + 4x + 6 = 9
7x = 9 - 6
7x = 3
x = 3/7
From equation (1), let replace the value of x to be 3/7
So,
y = 2x + 3
y = 2(3/7) + 3
y = 6/7 + 3
y = 27/7
Write the equation of a line in point-slope form that is parallel to the line y=2x-5 and goes through the point (-1,4)
(y-4) = 2(X+1)
Step-by-step explanation:
Hey there!
The given eqaution is; y = 2x-5.......(i)
Now; As the eqaution is in the form of y= mx+b.
Slope(m1) = 2.
As per the condition of parallel lines, slope of the 1st equation (m1) = slope of 2nd eqaution (m2).
Therefore, m1= m2= 2
Now, use one point formula for finding the eqaution of the line which passes through the point.
(y-y1) = m2(x-x1)
~ Put all values.
(y-4) = 2(X+1)
You can simply write upto here. But it you want to make it simplified form then, (look below)
~ simplify it.
y = 2x +2+4
The eqaution of the line which is parallel to y = 2x -5 and point (-1,4) is y = 2x + 6.
Hope it helps.....
Answer: y - 4 = 2(x + 1)
Step-by-step explanation:
The point slope form formula says that y - b = m(x-a) where m is the slope,b is the y coordinate of a given point , and a is the x coordinate of the same point.
Remember that parallel lines have the same slopes but different y-intercepts, meaning that m will equal to 2 because the slope for the line y=2x-5 is 2.
m will be 2, b will be 4 , and a will be -1.
y - 4 = 2(x - (-1) which reduces to
y - 4 = 2(x + 1)
Ms. Van Tress has 134 students. She sees 38 students before lunch and 96 students after lunch.
What percentage of her students does she see before lunch? After lunch? (Round your answers to
the nearest whole number percent)
Answer:
[tex]\%Percent = 28\%[/tex] ---- Before Lunch
[tex]\%Percent = 72\%[/tex] --- After Lunch
Step-by-step explanation:
Given
[tex]Total = 134[/tex]
[tex]Before\ Lunch = 38[/tex]
[tex]After\ Lunch = 96[/tex]
Required
Determine the percentage of students seen in both cases.
This percentage is calculated by dividing the number of students seen by the total number of students. Then multiplied by 100%
i.e
[tex]\%Percent = \frac{Seen}{Total} * 100\%[/tex]
- Before Lunch;
[tex]\%Percent = \frac{Before\ Lunch}{Total} * 100\%[/tex]
[tex]\%Percent = \frac{38}{134} * 100\%[/tex]
[tex]\%Percent = \frac{3800\%}{134}[/tex]
[tex]\%Percent = 28\%[/tex] --- approximated
- After Lunch;
[tex]\%Percent = \frac{After\ Lunch}{Total} * 100\%[/tex]
[tex]\%Percent = \frac{96}{134} * 100\%[/tex]
[tex]\%Percent = \frac{9600\%}{134}[/tex]
[tex]\%Percent = 72\%[/tex] --- approximated
Calculate the speed of a wave with a frequency of 2 Hz, amplitude of 3m, and a wavelength of 10m
The speed of a wave is the product of the wavelength and its frequency.
The speed of the wave is 20m/s
Given
[tex]\lambda = 10m[/tex] --- the wave length
[tex]f =2Hz[/tex] --- the frequency
[tex]A = 3m[/tex] --- the amplitude
The speed of wave (v) is calculated as follows:
[tex]v =f\lambda[/tex]
Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]
[tex]v = 2Hz \times 10m[/tex]
[tex]v = 20ms^{-1}[/tex]
Hence, the speed of the wave is 20m/s

19 more than 9 times a number is less than or equal to 163. Which of the following represents the solution set of this problem?
Answer:
x ≤ 6
Step-by-step explanation:
Let the unknown number be x;
9 times the number is expressed as 9x
9 more than 9 times a number is expressed as 9x + 9
9 more than 9 times a number is less than or equal to 163 is then expressed as;
9x + 9≤ 63
≤ is the less than or equal to sign
Find the solution;
9x ≤ 63 - 9
9x≤54
x ≤ 54/9
x≤ 6
Hence the required solution is x ≤ 6
