Water boils at different temperatures at different elevations. The boiling temperature of the water is 212F at sea level (0 feet) but drops about 1.72F for every 1,000 feet of elevation. Write a formula for the boiling point at a given elevation. Then solve the formula for the elevation when the boiling point for water is 190F. Question content area bottom.
Determine a formula for the boiling point b, in degrees Fahrenheit, at elevation h, in feet.
When the boiling point is 190F, the elevation is about
The formula used for given problem is y = mx+ b.
Slope intercept form: what is it?Slope-intercept form: A line with m as the slope and m and c as the y-intercept makes up the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.
This relationship is linear. Let y be the boiling point and let x be the altitude in feet.
We need the equation y = mx+ b for a linear one.
This is a linear relationship. Let x = the altitude in feet and y be the boiling point
For a linear equation, we want y = mx+ b
From the description m = -1.72/1000 and when x = 0, y = 212, so b = 212
y = -1.72/1000 + 212
B) When y = 190
190 = -1.72/1000x + 212
1.72x/1000 = 22
x = 22000/1.72 ≈ 12791 feet
When the boiling point is 190°F, the elevation is about 12791 ft.

(b) What is the change in volume of the solution after 15 seconds? Show necessary work. (c)What does the change in volume after 15 seconds mean in the real world? Answer in complete sentences.
A) The change in the volume of solution in the tank after 1 minute is;
-3⁷/₁₅ liters per minute
B) The change in volume of the solution after 15 seconds is; -13/15 liters per minute.
C) What change in the volume of solution in the tank after 15 seconds means is that there is a decrease in the volume of solution in the tank by 13/15 liters per minute.
What is the rate of change?The given parameters of the solution in the tank are;
The rate at which the solution enters the tank, V = 16³/₄ liters per minute

my gross annual salary is $38,256. Each paycheck, I have 12% withdrawn for federal
taxes, 6.2% withdrawn for Social Security and 1.45% withdrawn for Medicare. There
are no other deductions. How much my monthly paycheck?
Answer:
$2561.56========================
GivenAnnual gross salary = $38256,Deductions = 12%, 6.2% and 1.45%.SolutionFind the monthly gross and subtract all the deductions.
Monthly gross salary is:
$38256/12 = $3188Total deductions:
12% + 6.2% + 1.45% = 19.65%Monthly paycheck is:
$3188 - 19.65% = $3188(100 - 19.65)/100 =$2561.56 (rounded to the nearest cent)Answer:
$2,561.56
Step-by-step explanation:
Income:
Gross annual salary = $38,256Deductions:
Federal tax = 12%Social Security = 6.2%Medicare = 1.45%Total deductions:
⇒ 12% + 6.2% + 1.45% = 19.65%
If 19.65% of the gross salary is deducted, the percentage remaining will be:
⇒ 100% - 19.65% = 80.35%
Find 80.35% of the gross annual salary:
⇒ 80.35% of $38,256
⇒ 0.8035 × 38256
⇒ 30738.696
Divide this by 12 to find the value of the monthly pay check:
⇒ 30738.696 ÷ 12 = 2561.558
Therefore, the monthly pay check is $2,561.56 (nearest cent).

Considering the provided points and information, we are going to calculate the requested slope, so we obtain the following:
m=(y2-y1)/(x2-x1)
m=(6-5)/(4-1)
m=1/3
Finally we obtain that the slope of the line is 1/3.
What is the equation of the line that is parallel to the given line and passes through the point (â€"2, 2)? y = one-fifthx 4 y = one-fifthx twelve-fifths y = â€"5x 4 y = â€"5x twelve-fifths
The equation of the line that is parallel to the given line and passes through the point (–2, 2) is: B. y = 1/5(x) + 12/5
How to calculate the slope of a line?In order to determine the equation of this line, we would first of all calculate its slope. Mathematically, the slope of any straight line can be calculated by using this formula;
[tex]Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope\;,m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
By critically observing the graph of the line, we can logically deduce the following points:
Point (x, y) = (0, -3)
Point (x, y) = (-5, -4)
Substituting the given points into the formula, we have;
Slope = (-4 - (-3))/(-5 - 0)
Slope = (-4 + 3)/(-5)
Slope = -1/-5
Slope = 1/5
In Geometry, two (2) lines are parallel under the following conditions:
m₁ = m₂
Note: m represents the slope.
Mathematically, the point-slope form of a line is given by this equation:
y - y₁ = m(x - x₁)
Where:
x and y are the points.m represents the slope.At point (-2, 2), we have:
y - 2 = 1/5(x - (-2))
y - 2 = 1/5(x + 2)
y - 2 = x/5 + 2/5
y = x/5 + 2/5 + 2
y = x/5 + 12/5
y = 1/5(x) + 12/5

The value of given code is 58 and the value of a=8, b=7, c=-3, d=6, e=1, f=2 for the given puzzles using the exponential identities applied to the puzzles. on substituting the given values to f(b+d)+a(e-c)= 2(7+6)+8(1-(-3))= 58.
What is exponent?The number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as 23) means: 2 x 2 x 2 = 8. 2 x 3 = 6 does not equal 23. Keep in mind that a number raised to the power of one is itself.
What is exponential identity?If a>0 and b>0, the following applies to all real numbers x and y:
a^x.a^y = a^(x+y)
a^x/a^y = a^(x-y)
a^x.b^x=(ab)^x
(a/b)^x = a^x/b^x
a^0=1
a^-x= 1/ a^x
(x^a)^b= x^(ab)
For the puzzle 1,
we use the property a^x.a^y = a^x+y
x^4.x^a=x^12
4+a=12
a=8
For puzzle 2,
we use the property a^x/a^y = a^x-y
y^b/y^5=y^2
b-5=2
b=7
For puzzle 3,
we use the property a^-x= 1/ a^x
3^c=1/3^3
c=-3
For puzzle 4,

Graph the solution set of the inequality and write the solution using interval notation. Please give me a step by step explanation.
We have the inequality:
-4 < (3x - 2)/5 ≤ 6
We multiply all the sides by 5:
-4*5 < 5*(3x - 2)/5 ≤ 6*5
-20 < 3x - 2 ≤ 30
Now, we add 2 to all the sides of the inequality:
-20 + 2 < 3x - 2 + 2 ≤ 30 + 2
-18 < 3x ≤ 32
Finally, we divide by 3:
-18/3 < 3x/3 ≤ 32/3
-6 < x < 32/3
Now, using interval notation:
x = (-6, 32/3]
This means that x takes all the values greater than -6 and less or equal to 32/3. Graphically, this is:

The second angle of a triangle is 12 less than the first angle. The third angle is two times the first. Find the
three angles.
First angle:
Second angle:
Third angle:
Answer:
First angle: 48°
Second angle: 36°
Third angle: 96°
Step-by-step explanation:
The sum of the three angles of a triangle = 180°
Let the measure of the first angle be a°
Then second angle measure = (a - 12)°
Third angle measure = 2a°
Adding up all these should equal 180°
⇒ a + a - 12 + 2a = 180
⇒ 4a - 12 = 180
⇒ 4a = 180 -+ 12
⇒ 4a = 192
⇒ a = 192/4 = 48°
Thus the first angle is 48°
Second angle = 48 - 12 = 36°
Third angle = 2 x 48 = 96°

There are 13 diamond cards.
Hence,
[tex]\begin{gathered} \text{Diamond cards = 13} \\ \text{Total cards = 52} \end{gathered}[/tex]Probability is calculated by;
[tex]\text{Probability}=\frac{n\text{ umber of required outcomes}}{n\text{ umber of total or possible outcomes}}[/tex]Thus, the probability of drawing a diamond on the first draw is;
[tex]\begin{gathered} \text{Probability of drawing a diamond}=\frac{n\text{ umber of diamond cards}}{\text{total number of cards}} \\ \text{Probability of drawing a diamond}=\frac{13}{52} \\ \text{Probability of drawing a diamond}=\frac{1}{4} \\ P(D_1)=\frac{1}{4} \end{gathered}[/tex]Since two draws are made with replacement, the cards are completed back again before the next draw.
Hence, the probability of drawing a diamond on the second draw is;

Equation at the end of step : y - ((0 - ([tex]\frac{7}{3}[/tex] • x)) + [tex]\frac{5}{2}[/tex]) = 0
The left denominator is : 3 The right denominator is : 2
Least Common Multiple: 6
y - [tex]\frac{(15-14x)}{6}[/tex] = 0
y • 6 - [tex]\frac{(15-14x)}{6}[/tex] [tex]\frac{6y + 14x - 15}{6}[/tex]
[tex]\frac{ 6y + 14x - 15}{6}[/tex]
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 2.500 and for x=2.000, the value of y is -2.167. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -2.167 - 2.500 = -4.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -4.667/2.000 = -2.333
x-intercept = 15/14 = 1.07143
y-intercept = 15/6 = 5/2 = 2.50000
