The expression to represent the change in elevation would be 13 - 150.
The change in elevation would be - 137 feet.
How to find the change in elevation?The change in elevation refers to the difference between the elevation that a person ends up in, from the elevation that they started out at.
The change in elevation for the goat would therefore be:
= Ending elevation - Starting elevation
= 13 - 150
= - 137 feet
In conclusion, the change in elevation of the goat in its travels was - 137 feet.

in larg cities, people often take taxi to get from one place to another. what is the cost per mile of taxi ride how much is 47-mile taxi ride
People in large cities use taxis to get from one location to another; the cost is $25.20 every 36 miles, and a 47-mile taxi ride will cost $32.9.
What is the multiplication and division rule?Multiplication Rule If events A and B occur in the same sample space, the probability of both A and B occurring is equal to the probability that A occurs multiplied by the probability that B occurs, given that A has occurred.
Returning to the previous example, the first response is correct because it follows the BODMAS principles, which state that division can be done before multiplication and must be done before addition. Multiplication happens before addition.
Given,
Cost every 36 miles = 25.20
Cost of one mile = Cost for 36 miles / 36
Cost of one mile = 25.20/36
Cost of one mile = 0.7
Cost of 47 miles = Cost of one mile × 47
Cost of 47 miles = 0.7 × 47
Cost of 47 miles = 32.9
47 miles taxi ride will cost 32.9
The complete question is:

Which of the following coordinate points have undergone an enlargement and reduction? Select all that apply.Group of answer choices(5, -1) --> (10, 2) --> (20, 4)(1, 1) --> (6, 6) --> (1, 1)(4, 9) --> (20, 34) --> (20/45, 1)(3, 0) --> (9, 0) --> (18, 0)(0, -5) --> (0, 5) --> (0, 30)
By definition, you know that dilations have a scale factor, this is labeled k. To dilate something in the coordinate plane, multiply each coordinate by the scale factor.
If there is a reduction, then 0 < k < 1.
If there is an enlargement, then k > 1.
[tex](x,y)\rightarrow(kx,ky)[/tex]So, you have

What are fraction ?A fraction is a mathematical symbol representing any quantity of equal parts, and it also represents a portion of a whole. When employed in conversational English, a fraction—such as one-half, eight-fifths, and three-quarters—indicates the number of components of a particular size.
Calculationinlet pipe will fill the pool in 34 hours. Every hour, it fills 1/34 of the pool
Outlet pipe will empty the pool in 35 hours. Every hour, it empties 1/35 of the pool.
In x hours we want 1/2 the pool to fill, since half is already filled.
We want (x/34) - (x/35) = 1/2

Step-by-step explanation:
A line drawn on the coordinate plane passes through the points (1, 4) and (2, 7). What is the equation of the line?
Thus, the equation of the straight line passing through the point (1,4) and (2,7) is: y=3x+1
A line passing through the coordinate plane also passes through points (1,4) and (2,7)
Let point(1,4) be=P
let point(2,7) be=Q
The formula for the equation of a straight line when two points are given is given as:
y-y1=m X (x-x1) + c
where m=y2-y1/x2-x1
here y= Y axis
x= X axis
m= Slope of the line
c= constant
Here taking P as point 1 and Q as point 2 we get:
x1=1 y1=4
and
x2=2 y2=7
m=y2-y1/x2-x1
Now putting values
m=(7-4)/(2-1)
m=3/1
Thus m=3
now putting values in the equation
(y-4)=3(x-1) +c
y-4=3x- 3+c
y=3x-3+4+c
y=3x+1+c
Since Line passes through point Q(2,7) it satisfies the equation.
now putting the values of point Q in the equation to get the constant:
y=3x+1+c
(7)=3(2)+1+c
7=6+1+c
7=7+c
7-7=c
c=0
Thus, the constant is 0.
Thus, the equation of the straight line passing through the point (1,4) and (2,7) is: y=3x+1

Two planes at started to take off at the same time.

What would you change to make sure both planes rise at the same rate?
a. Since the vertical component of velocity v' = 241.05 mph > v" = 229.43 mph, the first plane is rising faster
b. I would change the angle of elevation of both planes
a. How to find which plane is rising faster?Two planes at started to take off at the same time. Plane One took off from the tarmac going 375 mph at an angle of elevation of 40° and Plane Two took off from the tarmac going 400 mph at an angle of elevation of 35°, to fidn which plane is rising faster, we compute their vertical component of velocity of the plane .
What is the vertical component of velocity?The vertical component of velocity is v' = vsinФ where
v = speed and Ф = angle of elevationFor the first plane
v = 375 mph and Ф = 40°So, v' = vsinФ
= (375 mph)sin40°
= (375 mph) × 0.6428
= 241.05 mph
For the second plane
v = 400 mph and Ф = 35°So, v" = vsinФ
= (400 mph)sin35°
= (400 mph) × 0.5736
= 229.43 mph
Since v' = 241.05 mph > v" = 229.43 mph
So, the first plane is rising faster
b. What would you change to make sure both planes rise at the same rate?To make both planes rise at the same rate, I would change the angle of elevation of both planes

what is the slope of a line perpendicular to the line whose equation is x+y=9
Answer:
perpendicular slope = 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x + y = 9 ( subtract x from both sides )
y = - x + 9 ← in slope- intercept form
with slope m = - 1
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-1}[/tex] = 1

2) One of the formulas to find out the area of a triangle is:
[tex]S=\frac{ab\cdot\sin (\alpha)}{2}[/tex]Plugging the given data into the formula we have:

Carolina needs a total of $6.50 in quarters for a coin-operated car wash. He already has $1.50. Which equation can be used to find g, the
additional quarters Carolina needs in order to have enough money for the car wash?
Answer: 20 quarters
Step-by-step explanation:
As we look at this problem we can convert $6.50 dollars into 26 quarters. Us already knowing that Carolina has $1.50 (6 quarters) we can take the two numbers and minus both of them. 26 quarters ($6.50) - 6 quarters ($1.50) = 20 quarters($5.00)
Step-by-step explanation:
every $ is equivalent to 4 quarters.
every half-$ is equivalent to 2 quarters.
after all, 1 quarter = $0.25.
so, the equation is
4×1.5 + g = 4×6.5
or simplified
6 + g = 26
and from there we get then immediately that
g = 20

Michelle wants to try a few of the family meals so she can have her babysitter over for dinner a few nights this month . One family meal costs $9.99 if Michelle cooks dinner for her babysitter three times this month using the family package and still purchases her classic meal package how much will Michelle pay for her subscription this month
Michelle will pay $154.97 if she cooks dinner for her babysitter three times this month using the family package and still purchases her classic meal package.
What is meant by cost?A cost function is a mathematical formula that shows how production costs change at different output levels. In other words, it calculates the total cost of production based on the quantity produced. The cost function can be used to calculate the average cost, which is the amount of money it costs to produce one unit on average.
The average cost function is A(x)=C(x)x A (x) = C (x) x A (x) = C (x) x, where x>0. The average cost per unit is calculated by dividing the total cost by the number of units produced.
Given,
Monthly cost of $125 per month for their classic meals
and one family meal costs $9.99
if Michelle cooks dinner for her babysitter three times this month using the family package, the the cost of 3 family meal cost will be
3 × $9.99 = $29.97 and still purchases her classic meal package
Hence, the total pay will be $125 + $29.97 = $154.97
