Answer:
21.9 feet
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.
Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?
Given parameters
Altimeter of vivian at its lowest point = -9.6 feet
Altimeter of vivian at the top of the wheel = 12.3feet
Note that the sea level is at 0 feet.
change in Vivian's elevation from the bottom of the Ferris wheel to the top is expressed as:
= (12.3-0)+(0-(-9.6))
= 12.3+(0+9.6)
= 12.3+9.6
= 21.9 feet
From the gotten value, it can be seen that the change in Vivian's elevation from the bottom of the Ferris wheel to the top is a positive value.
The value is positive because vivian keeps moving to the top of the wheel (above the sea level). The values above the sea level is always positive.
Answer:Hide Sample Answer
The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

The change in Vivian's elevation is a positive number because her elevation increased as she moved from the bottom of the Ferris wheel to the top.

Rob peeled 125 oranges in 5 hours. At that rate, how many oranges
would he peel in 12 minutes?
Answer:
5 oranges in 12 minutes
Step-by-step explanation:
[tex]125 \div 5 = 25[/tex]
[tex]25 \div 60 = 0.41[/tex]
[tex]0.41 \times 12 = 5[/tex]
what i did here was I took the original amount (125), divided it by 5 which is 25 oranges per hour
1 hr = 60 mins
then I divided 25 oranges by 60 mins, then times it by 12 to get 5 around 5 oranges in 12 minutes.
Answer:
[tex]\boxed {\tt 5 \ oranges}[/tex]
Step-by-step explanation:
Let's set up a proportion.
[tex]\frac{oranges}{minutes} =\frac{oranges}{minutes}[/tex]
He can peel 125 oranges in 5 hours. First, let's find the minutes in 5 hours.
There are 60 minutes in 1 hour, so multiply 60 and 5 (60*5=300). There are 300 minutes in 5 hours.
[tex]\frac{125 \ oranges}{300 \ minutes}=\frac{oranges}{minutes}[/tex]
We don't know how many oranges he can peel in 12 minutes. So we say he can peel x oranges in 12 minutes.
[tex]\frac{125 \ oranges}{300 \ minutes}=\frac{x \ oranges}{12 \ minutes}[/tex]
[tex]\frac{125 \ }{300 \ }=\frac{x \ }{12 }[/tex]
Solve for x by isolating it. x is being divided by 12. The inverse of division is multiplication. Multiply both sides of the proportion by 12.
[tex]12*\frac{125 \ }{300 \ }=\frac{x \ }{12 \ }*12[/tex]
[tex]12*\frac{125 \ }{300 \ }=x[/tex]
[tex]12*0.416666667=x[/tex]
[tex]5=x[/tex]
Rob can peel 5 oranges in 12 minutes.
A plane takes off from a runway and begins its climb. The plane takes off at a constant acceleration of 20 LaTeX: m /s^{2} . Once it reaches altitude it moves at 246 m/s, and maintains that speed. If it continues at this speed for 93 min, how far would the plane have traveled from the time took off?
Answer:
The plane have traveled 1512.9 m from the time took off
Step-by-step explanation:
Acceleration [tex]a = 20m/s^2[/tex]
Initial speed = u = 0
Final speed = v = 246 m/s
Time = t = 93
We are supposed to find how far would the plane have traveled from the time took off
We will use equation of motion
[tex]v^2=u^2+2as\\(246)^2=2\times 20 \times s\\\frac{(246)^2}{2 \times 20}=s\\1512.9 m=s[/tex]
Hence The plane have traveled 1512.9 m from the time took off

find value of x so that f(x)=7
Answer: -3
Step-by-step explanation:
0,4
2,2
Find slope: 2 - 4 = -2
2 - 0 = 2
-2/2 = -1 is slope
7 = -1x + 4
subsitute -1 for x
7 = -1(-1) + 4
1 + 4
The required simplified value of the x is -3 for f(x) = 7.
Given that,
To determine the value of x so that f(x)=7.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
As shown in the graph,
The slope of the line is m = -1
And points through which the line is passing are (0,4) and (4, 0)
The equation of the line is given as,
(y - 4) = -1 (x - 0)
y -4 = -x
y + x = 4
Now,
y = 4 - x
putting y = f(x)
f(x) = 4 - x
Now,
we have f(x) = 7
7 = 4 - x
x = -3
Thus, the required simplified value of the x is -3 for f(x) = 7.

good luck and hope this helped a bit!
The correct answers for the given problem are: (a) The distance travelled on the cycle in the first 14 seconds is 96 m and (b)The acceleration in the first 4 seconds is 2 m/s².
How to find the area under a graph?The area under a graph can be found by dividing the graph into equal intervals of very small width and then find the area of the rectangle for each intervals. After summing all the areas of rectangles the area under the graph can be approximated.
The velocity time graph given in the problem can be used to find the distance travelled.
The distance travelled in first 14 seconds is equal to the area of the graph from t = 0 to t = 14.
This area consists of a triangle of height h = 8 and base b = 4 and a rectangle of length l = 8 and width b = (14 - 4) = 10.
Now, the total area is given as,
1/2 × b × h + l × b
= 1/2 × 4 × 8 + 8 × 10
= 16 + 80
= 96
(b) The acceleration is given as the rate change of velocity with respect to time.
The acceleration in first 4 seconds is given as,
a = (8 - 0)/4
= 2
Hence, the distance travelled in first 14 seconds and acceleration in first 4 seconds is given as 96 m and 2 m/s² respectively.

Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Write an equation for P,P, in terms of x,x, representing Cooper's total pay on a day on which he sells xx dollars worth of computers.
Answer:
P= 0.015x+60
Step-by-step explanation:
thats the right answer
If Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Then P = 0.015x + 60 is total pay.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Cooper's base pay is $60 per day
He gets $60 even for not selling computers,
meaning P= 60 when x=0, which is the y-intercept.
Now if Cooper makes a commission of 1.5% for all sales,
His earning will be increased by 1.5%.
The percentage value should be changed to decimal value. By Dividing 1.5 by 100
1.5/100=0.015
The amount of money earned in a given day increases $0.015 for each $1 of sales made.
Here x, representing Cooper's total pay on a day on which he sells x dollars of worth computers.
P = 0.015x + 60
Hence P = 0.015x + 60 is the total pay of cooper .

Answer:
(21.9, 66.3)
Step-by-step explanation:
Given the coordinates A (25.5, 60.1) and C (18.3, 72.5)
The formula for calculating the midpoint is expressed as;
M = {(x1+y1)/2, (y2+y1)/2}
X = (x1+y1)/2
Y = (y2+y1)/2
From the given coordinates A (25.5, 60.1) and C (18.3, 72.5)
x1 = 25.5, y1= 60.1, x2 = 18.3 and y2 = 72.5
X = (25.5+18.3)/2
X = 43.8/2
X = 21.9
Y = (72.5+60.1)/2
Y = 132.6/2
Y = 66.3
The midpoint of the coordinates M will be M(21.9, 66.3)
