A model of the Eiffel Tower
uses a scale of 1 cm - 4 meters.
If the model is 75 a centimeters
tall, what is the actual height
of the Eiffel Tower?
Answer:
The correct answer is A. The actual height of the Eiffel Tower is 301 meters.
Step-by-step explanation:
Given that a model of the Eiffel Tower uses a scale of 1 cm - 4 meters, if the model is 75 1/4 a centimeters tall, to determine what is the actual height of the Eiffel Tower the following calculation must be performed:
1 = 4
1/4 = 0.25
75.25 x 4 = X
301 = X
Therefore, the actual height of the Eiffel Tower is 301 meters.

A. 93
B. 57
C. 132
D. 123
Answer:
B
Step-by-step explanation:
The interior angles of a triangle always add up to 180 degrees.
We have two angles already and they add up to 60+63=123 degrees
180-123=57
so the remaining angle is 57 degrees
9514 1404 393
Answer:
D. 123°
Step-by-step explanation:
The external angle is equal to the sum of the remote internal angles.
m∠1 = 60° +63°
m∠1 = 123°

What is the probability of choosing a heart or a six from a deck of cards? Type your answer as a fraction.
Answer:
17/52
Step-by-step explanation:
The value V (in dollars) of a milling machine depends on the number of hours x it is operated as
given by the formula V = 750,000 - 120x. After one year, the value of the milling machine is
between $450,000 and $480,000.
Which range for the hours the machine is operated does this correspond to?
Basically, you have to understand the logic of a function.
V = 750,000 - 120xIf I plug in a value into V that represents the value of a milling machine, if I simplify the equation, I will be able to find x, the corresponding time to the value of the milling machine.
Knowing this logic, we can plug in $450,000 and $480,000, and then we will have two x-values. Then we can just find the range of the x-values to find our answer! :)
Let's go.
V = 750,000 - 120x
Plugged in 450,000 for V so now we can simplify the equation and find out what is the corresponding x-value for this value at this certain time.
450,000 = 750,000 - 120x
-450,000 -450,000
0 = 750,000 - 120x
+120x on both sides to isolate x
120x = 300,000
x = 2500
So, our first x-value in the range is 6250 hours. Now, let's plug in the larger value to find out the other x-value in the range.
V = 750,000 - 120x
480,000 = 750,000 - 120x
-480,000 -480,000
0 = 270,000 - 120x
Add 120x on both sides to isolate x
120x = 270,000
x = 2250
So, we found 2250 and 2500. So, the range of hours it corresponds to is 2250-2500.

How do I solve this using the Pythagorean theorem
Answer:
x=8
Step-by-step explanation:
Remember that the variables a and b in the formula are the legs and c is the hypotenuse. So that means that 15 and x are the legs and 17 is the hypotenuse. Plug those numbers where they go in the formula like below:
15^2+x^2=17^2
Go ahead and square the 15 and 17 to simplify it a little.
225+x^2=289
Now, get the x by itself by subtracting 225 from each side
x^2=64
Take the square root of each side to remove the squared on x and solve.
x=8

Find the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis. Verify your results using the integration capabilities of a graphing utility. y = e^(x-1), y=0, x=1, x=2
Answer:
the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis is;
[tex]\frac{\pi }{2} [e^2 - 1 ][/tex] or 10.036
Step-by-step explanation:
Given the data in the question;
y = [tex]y = e^{(x - 1 )[/tex], y = 0, x = 1, x = 2.
Now, using the integration capabilities of a graphing utility
y = [tex]y = e_2}^{(x - 1 )_[/tex], y = 0
Volume = [tex]\pi \int\limits^2_1 ( e^{x-1)^2} - (0)^2 dx[/tex]
Volume = [tex]\pi \int\limits^2_1 ( e^{x-1)^2 dx[/tex]
Volume = [tex]\pi \int\limits^2_1 e^{2x-2}dx[/tex]
Volume = [tex]\frac{\pi }{e^2} \int\limits^2_1 e^{2x}dx[/tex]
Volume = [tex]\frac{\pi }{e^2} [\frac{e^{2x}}{2}]^2_1[/tex]
Volume = [tex]\frac{\pi }{2e^2} [e^4 - e^2 ][/tex]
Volume = [tex]\frac{\pi }{2} [e^2 - 1 ][/tex] or 10.036
Therefore, the volume of the solid generated by revolving the region bounded by the graphs of the equations about the x-axis is;
[tex]\frac{\pi }{2} [e^2 - 1 ][/tex] or 10.036

Consider this linear function:
y = -23 – 5.
Plot all of the ordered pairs for the values in the domain.
D: {-6, -5, -2,0, 1}
Answer:
Step-by-step explanation:
Domain of a function defines the input values (x-values) of the function.
Given linear function is,
y = -2x - 5
Domain of the function is,
{-6, -5, -2, 0, 1}
By substituting the values of x in the equation we can get y-values (output values).
Input-output table for the function,
x -6 -5 -2 0 1
y 7 5 -1 -5 -7
Now we can plot these points of the graph.
Why Was A Book In The Frying Pan On The Stove?
Consider the line - 5x – 3y = 7.
(a) What is the slope of a line parallel to this line?
(b) What is the slope of a line perpendicular to this line?
Answer:
a: m=5/3
b: m=-3/5
Step-by-step explanation:
first, before answering the questions, let's change the line from standard form (ax+by=c), where a and b are free coefficients into slope-intercept form (y=mx+b), where m is the slope and b is the y intercept
subtract 5x from both sides
-3y=-5x+7
divide by -3
y=5/3x-7/3
now to answer part a:
parallel lines have the same slopes, but different y intercepts.
the slope of the given line is 5/3, so therefore, a parallel line to the line y=5/3x-7/3 will also be 5/3
part b:
perpendicular lines have slopes that are negative and reciprocal; if you multiply them together, the result is -1
so to find the slope of a perpendicular line, use this formula:
5/3m=-1
multiply by 3/5 to isolate the variable
m=-3/5
therefore the slope of a perpendicular line will be -3/5
hope this helps!

X-2 is a factor of f(x) = x3 – 2x2 + ax +
+18. State the remainder when f(x) divided
by x-9.
Answer:
answer is in the picture above
Answer:
remainder: 504
Step-by-step explanation:
x³ – 2x² + ax +18 = x²(x-2) - 9*(x-2)
a = -9
(x³ – 2x² - 9x +18) / (x-9) = (x² +7x + 54)(x-9) + 504 ... long division

Ratio of the ages of three children is 2:5:1. The sum of their ages is 32 years. Find the ages of the youngest and the eldest
child.
Answer:the ages of the youngest and the eldest is 4 years and 20 Years respectively
Step-by-step explanation:
Ratio of the ages of three children is 2:5:1.
Total ratio =2+5+1=8
So that
the 1st Child's age =2/8 x 32=8 years
2nd Child's age =5/8 x 32= 20 years
3rd Child's age =1/8 x 32= 4 years
Therefore the ages of the youngest and the eldest is 4 years and 20 Years respectively.
The area of a rectangle is 96 cm2. If the breadth of the rectangle is 8cm, find its perimeter
Answer:
area = length x width
96/8= 12 = something i have no idea what is breadth, but it doesnt matter
perimeter = 2(length) + 2(width)
2(12) + 2(8)=40cm
hope that answers your question
ps. fix your typing...skill, or word vocabulary thing...
Step-by-step explanation:
Answer:
40 cm
Step-by-step explanation:
Data:
Area (a): 96 cm
Width (b): 8 cm
a = b•h
96 = 8•h
96/8 = h
12 = h
The perimeter is the sum of all the sides, so.
Perimeter:
12+12+8+8 = 40
