Given :
An airplane cuts through the morning sky for every 1,000 feet that he climbs the outside temperature drops 20° F.
To Find :
The rate of the temperature change in degrees Fahrenheit per foot.
Solution :
Let, rate of the temperature change in degrees Fahrenheit per foot is x.
So,
[tex]x = \dfrac{20}{1000}\ ^oF/foot\\\\x = 0.02 ^oF/foot[/tex]
Therefore, rate of the temperature change in degrees Fahrenheit per foot is 0.02.
Hence, this is the required solution.
Answer:
this is really late, but for the people who need it now the real answer is
Step-by-step explanation:
The airplane is rising, so the change in elevation is +1,000 feet. The temperature is dropping, so the change in temperature is -20 degrees Fahrenheit.

3.It usually takes Claude 40 minutes driving at 48 miles per hour to go from home to work. But due to road maintenance today, Claude has to take a detour, which makes the trip 8 miles longer than usual. What is the minimum speed Claude should travel so that he can reach the destination in less than 48 minutes?
A.30 miles per hour
B.56 miles per hour
C.50 miles per hour
D.64 miles per hour
*please make sure you answer all the questions please and thank you.
Answer:
x and y can be any two numbers greater than zero such that y is also greater than x
D.no more than 45
C.50 miles per hour
Step-by-step explanation:
Let the two numbers be such that x< y because we have been given y/x>1 and x/y< 1 .
Suppose we take y= 9 and x= 3 then
9/3 > 1
3>1
Also
3/9 < 1
1/3 < 1
x and y can be any two numbers greater than zero such that y is also greater than x
2. Total weight that can be carried is 3000 pounds.
The big machine is 300 pounds. The weight that the truck can carry beside the big machine is 3000-300= 2700 pounds.
The smaller machines weigh 60 pounds
The number of smaller machines that can be carried is 2700 ÷ 60= 45 other than the big machine.
3. Total distance = Speed * time
= 48 * (40/60) = 32 miles
New distance = 32+ 8= 40 miles
New time = 48 minutes
Speed = distance / time = 40/ 48/60= 50 miles per hour

Answer:
The equation of new line is: [tex]\mathbf{y=\frac{3}{4}x-12}[/tex]
Option H is correct.
Step-by-step explanation:
We need to write an equation for the line that is parallel to the given line [tex]y=\frac{3}{4} x-9[/tex] and point (-8,-18)
The equation of required line will in in form [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We need to find slope m and b y-intercept for new line.
Finding slope:
When two lines are parallel, they have the same slope.
The slope of given line can be found by comparing the equation [tex]y=\frac{3}{4} x-9[/tex] with [tex]y=mx+b[/tex]
So, m = 3/4
The slope of new line will be: [tex]m=\frac{3}{4}[/tex]
Finding y-intercept:
Using slope m = 3/4 and point (-8,-18) we can find y-intercept
[tex]y=mx+b\\-18=\frac{3}{4}(-8)+b\\-18=-6+b\\b=-18+6\\b=-12[/tex]
So, y-intercept is b=-12
The equation of new line having m = 3/4 and b=-12 is:
[tex]y=mx+b\\y=\frac{3}{4}x-12[/tex]
So, the equation of new line is: [tex]\mathbf{y=\frac{3}{4}x-12}[/tex]
Option H is correct.

what is the value of MB between A and B?
Answer:
MB = 26
Step-by-step explanation:
AM = 2x - 3
MB = 5x + 1
AB = 21 - (-12)
= 21 + 12
= 33
According to the question M is between A and B. So,
[tex] \rm \longrightarrow AB = AM + MB \\ \\ \rm \longrightarrow 33 = (2x - 3) + (5x + 1) \\ \\ \rm \longrightarrow 2x - 3 + 5x + 1 = 33 \\ \\ \rm \longrightarrow (2x + 5x) + (1 - 3) = 33 \\ \\ \rm \longrightarrow 7x - 2 = 33 \\ \\ \rm \longrightarrow 7x - 2 + 2 = 33 + 2 \\ \\ \rm \longrightarrow 7x = 35 \\ \\ \rm \longrightarrow \dfrac{7}{7} x = \dfrac{35}{7} \\ \\ \rm \longrightarrow x = 5[/tex]
[tex] \therefore [/tex] Value of MB = 5 × 5 + 1
= 25 + 1

Answer:
[tex]m\angle BED = 34^\circ[/tex]
Step-by-step explanation:
Angles in a Circle
We need to recall some basic concepts.
An inscribed angle is the angle formed in the interior of a circle when two secant lines intersect.
An arc of a circle is a portion of the circumference of the circle.
Theorem: Inscribed angles subtended by the same arc are equal.
In the figure provided, the points BD form an angle of 34° and the arc BD.
Similarily, arc BD also has two secants BE and DE that form the angle BED.
Thus, applying the above theorem, angle BED and 34° are subtended by the same arc, and the measure of BED is also 34°
[tex]\mathbf{m\angle BED = 34^\circ}[/tex]

$1.90
$3.60
$0.65
$1.55
I'm not really understanding how to set this up
Answer: x = 21; y = 29.5
because 2y° and 59° are 2 opposing angles ⇒ 2y° = 59° ⇔ y = 29.5°
we also have: (3x - 4)° = 59° ( because of 2 parallel lines)
⇔ 3x = 59 + 4 = 63
⇔ x = 63/3 = 21

Which equation in standard form has a graph that passes through the point (5,-2) and has a slope of 7/2
A:7x - 2y=35
B:7x - 2y=39
C:7x - 2y=-31
d:7x - 2y=-24
Answer:
B
Step-by-step explanation:
Since it's MCQ and it's LHS is all 7x - 2y, you can simply sub in (5, -2) into each option and see which one has its LHS = RHS.
7(5) - 2(-2) = 35 + 4 = 39
Hence, option B is the answer.

Answer:
I seem to be late but I feel like the answer is X = 12.
Step-by-step explanation:
I will start out with my expression .
First step i take is adding 3 to both sides of the expression. [tex]\sqrt{x} +4 - 3+3 = 1 + 3[/tex] . This leaves me with [tex]\sqrt{x}+4 = 4[/tex].
My second step I will need to remove the check mark thingy away from the expression. In order for me to do that, I am going to have to square both sides of the expression giving me this! [tex]\sqrt{x} +4^{2} = 4^{2} = x +4 = 16[/tex] .
Now for my final step which will be to remove 4 from both sides of my expression. X + 4 – 4 =16 – 4 = x = 12.
Leaving me with my answer of X = 12

Graph the first equation, which has slope = −3 and y-intercept = 2, graph the second equation, which has slope = 1 and y-intercept = 4, and find the point of intersection of the two lines.
Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.
Graph the first equation, which has slope = 2 and y-intercept = −3, graph the second equation, which has slope = 4 and y-intercept = 1, and find the point of intersection of the two lines.
Answer:
C. Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.
The two equations are in slope intercept form which is y = mx + b where m is the slope and b is the y-intercept.
In the first equation (y = -2x + 3), -2 is the slope since it is the coefficient. "b" is 3 since it is the constant of the equation.
In the second equation (y = -4x -1), -4 is the slope is the coefficient, and the y-intercept is -1 since it is the constant.
To solve the equations graphically, graph them and find the point where they intersect.

Answer:
D.
Step-by-step explanation:
it can't be B or C since Function A has a greater y-intercept of 2. and if you graph function A you can see that Function B has a greater rate of change
Answer:
D
Step-by-step explanation:
The rate of change for the graph is 2 so we can rule anything out that shows A has a larger rate of change. Now we look at the y intercept on the graph which is -2. The one in the function is 2 so we eliminate anything that says B has a greater y intercept this should give you the answer
