Answer:
127 1/2 feet
Step-by-step explanation:
A model lighthouse uses a scale of 1/4 inch = 5 feet.
This means that 1/4 inch on the model represents 5 feet in actual life.
The height of the model lighthouse is 6 3/8 inches i.e. 51/8 inches.
The height of the actual lighthouse is:
1/4 inch = 5 feet
51/8 inches = x
Cross-multiply:
51/8 * 5 = 1/4 * x
=> x = 51/8 * 4 * 5
x = 127 1/2 feet
The height of the actual lighthouse is 127 1/2 feet.

Answer:
C = 14pi
Step-by-step explanation:
C = pi d
The radius is 7 so the diameter is
d = 2r
d = 2*7
=14
C = pi *14
C = 14pi
Answer:
Step-by-step explanation:
we know circumference of a circle = [tex]\pi[/tex]d
here radius = 7 mm
diameter = 2*7= 14mm
therfore circumference = [tex]\pi[/tex] * 14
ie C = 14[tex]\pi[/tex]
therefore 2nd option is the answer

Given l\\m and m<1= <60 and m1 = 60°, select all angles that are also equal to 60°.
8
2
6
7
5
4
Answer:
Angle 2, angle 3 and angle 4 will measure 60°
Step-by-step explanation:
From the figure attached,
'l' and 'm' are parallel lines and 't' is the transverse line.
m∠1 = m∠2 = 60° [Vertical angles]
m∠1 = m∠3 = 60° [Corresponding angles]
m∠1 = m∠4 = 60° [Alternate exterior angles]
Therefore, angle 2, angle 3 and angle 4 will measure the same as angle 1.
a cyclic quadrilateral is shown. x:y=3:7. work out the size of angle z
Step-by-step explanation:
x:y=3:7
x+y=180
3+7=10
180/10=18
to find x
18*3=54
x+10+z=180
54+10+z=180
64+z=180
z=180-64
z=116°
The measure of angle z of the cyclic quadrilateral will be 116 degrees.
What is a cyclic quadrilateral?If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral.
A cyclic quadrilateral is shown.
x / y = 3 / 7
y = 7x / 3
We know that the sum of the opposite angles of the cyclic quadrilateral is 180 degrees. Then the equation will be
x + y = 180°
x + 7x/3 = 180°
10x/3 = 180°
x = 54°
Then another equation is given as,
x + 10° + z = 180°
54° + 10° + z = 180°
z = 116°
The measure of angle z of the cyclic quadrilateral will be 116 degrees.

One tool used in genetics is called a pedigree chart,are there any advantages to using this tool?The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city. Write an exponential growth function to model this situation. Then find the population in 2009.
Answer:
A = 236,000 (1.04)^t
population in 2009 : 335,902 people
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential growth function:
A = P (1 + r) t
Where:
p = original population
r = growing rate (decimal form) = 4/100 = 0.04
t= years passed from 2000
A = population after t years
Replacing with the values given:
A = 236,000 (1+ 0.04)^t
A = 236,000 (1.04)^t
Population in 2009.
t = 2009-2000 = 9
A = 236,000 (1.04)^9
A = 335,902 people

What is the x-intercept of f-^1(x)?
Answer:
(2 1/2, 0)
Step-by-step explanation:
In the picture attached, the complete question is shown.
f(x) = 2 1/2 - 3 1/3 * x
or
f(x) = 5/2 - (10/3)*x
f^-1(x) is the inverse of f(x), which is obtained replacing f(x) by x, and x by y, and solving for y, as follows:
x = 5/2 - (10/3)*y
(10/3)*y = 5/2 - x
y = (5/2)*(3/10) - x*(3/10)
y = (3/4) - (3/10)*x
f^-1(x) = (3/4) - (3/10)*x
at x-intercept, f^-1(x) = 0,
(3/4) - (3/10)*x = 0
(3/4) = (3/10)*x
x = (3/4)*(10/3)
x = 5/2 or 2 1/2

HELPPPP PLEASE To make an international telephone call, you need the code for the country you are calling. The codes for country A, country B, and C are three consecutive integers whose sum is 78. Find the code for each country.
Answer:
25, 26, 27
Step-by-step explanation:
78/3=26, so one number is 26 and the other numbers have to equal 52, so the numbers have to either be 24,25,27,28. 25+27=52,
The codes for each country are 25, 26 and 27.
What are integers?Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."
Let three consecutive integers are n-1, n, n+1.
Then,
the sum of three consecutive integers is 78.
According to the question,
n - 1 + n + n + 1 = 78
3n = 78
n = 26
The integers are 25, 26 and 27.
Therefore, integers are 25, 26 and 27.

he curb weight of a new car is 3,347 pounds. How much does the car weigh?
Answer:
Step-by-step explanation:
I think it is 3,347. Because the curb weight is just the car without humans
Given that the curb weight of a new car is = 3347 pounds
Now we have to find the correct choice for the given weight of the car.
Given value is in pound while the choices are in ton.
Units are different so first task will be to get same units.
We know that 1 ton = 2000 pound
so to convert 3347 pound into ton, we will divide 3347 by 2000 and get 1.6735 ton.
Which lies between 1 and 2.
Hence final answer will be (c) between 1 and 2 tons.
Xavier and Jeanine each worked a shift today, selling tickets to the school fair for $ 12
each. Xavier worked the first shift. During Jeanine's shift, she sold 8 tickets. At the end
of the day, the total amount of money from tickets sold was $240. Which equation could
be used to determine x, the number of tickets Xavier sold ?
A. 12(X + 8) = 240
B. X(12 + 8) = 240
C. 12 + 8x = 240
D. 12x + 8 = 240
Answer: 12(X+8)=240
Step-by-step explanation: We then would have to do the distributive property and you end with 12x+96=240
Subtract 96 from each side
Then you end with
12x=144
You then divide 12 from each side and see that X=12!

B)-2
C)2/3
Answer:
A) -2/3
Step-by-step explanation:
To find the answer look at what it's asking you to do. (f/g) means to divide f(x) by g(x).
[tex](f/g)(x)=\frac{2x}{x^2+2}[/tex]
Now you need to find (f/g)(-1). Plug in -1 wherever there is an x and simplify.
[tex](f/g)(-1)=\frac{2*-1}{(-1)^2+2}\\ (f/g)(-1)=\frac{-2}{1+2}\\ (f/g)(-1)=\frac{-2}{3}[/tex]
Your answer is -2/3
Solve for a. ab+ c =d
Answer:
[tex]\frac{-c+d}{b}[/tex]
Step by Step:
Step 1: Subtract c from both sides:
ab + c + (−c) = d + (−c)
ab = −c + d
Step 2: Divide both sides by b:
[tex]\frac{ab}{b} = \frac{-c+d}{b}[/tex]
Step 3: Simplify:
a = [tex]\frac{-c+d}{b}[/tex]
Your mom is taking you shopping at the mall. She has $78 to spend on you. You already know that $18 of that money is for your school backpack. You need to get 2 shirts and 2 pairs of pants for your school uniform. The pants and the shirts cost the same amount for each. How much does each shirt or pair of pants cost?
Answer:
each coat $15
Step-by-step explanation:
$78-$18 divided by 4 =15
hope this helps :)
Answer:
The answer is that each shirt and pair of pants costs 15$
Step-by-step explanation:
So you have 78$, and you already need to buy a backpack so then you have 60$ dollars because the backpack is 18$, and 2 shirts and 2 pairs of pants is 4 pieces of clothing in all, 60$ divided by 4 pieces of clothing equals 15$ per piece of clothing (78 - 18 = 60 divided by 4 = 15)
Solve for the variable "d" in the following equation.
[tex]F=\frac{Gm_1 m_2}{d^2}[/tex]
[tex]F = \frac{Gm_{1}m_{2} }{d^{2} }[/tex]
F x [tex]d^{2}[/tex] = G[tex]m_{1}m_{2}[/tex]
[tex]d^{2}[/tex] = [tex]\frac{Gm_{1}m_{2}}{F}[/tex]
d = ±[tex]\sqrt{\frac{Gm_{1}m_{2}}{F} }[/tex]
Since "m1" and "m2" represent different masses, we can change them to different letters. This will make it easier to solve.
m1 = m
m2 = n
F = G*m1*m2/d^2 → F = Gmn/d^2
Steps to solve for d:
F = Gmn/d^2
~Multiply d^2 to both sides
d^2 * F = d^2 * Gmn/d^2
~Simplify
d^2 * F = Gmn
~Divide F to both sides
d^2*F/F= Gmn/F
~Simplify
d^2 = Gmn/F
~Take the square root of both sides
√d^2 = ±√Gmn/F
~Simplify
d = ±√Gmn/F
Since we are done solving for d, we can input "m1" and "m2" to replace "m" and "n".
d = ±√Gmn/F → d = ±√G*m1*m2/F
Therefore, the answer is [ d = ±√G*m1*m2/F ]

Find the distance between the complex numbers. z1 = 9 - 9i z2 = 10 - 9i
Answer:
The distance between the two given complex numbers = 9
Step-by-step explanation:
Explanation:-
Step(i):-
Given Z₁ = 9 - 9 i and Z₂ = 10 -9 i
Let A and B represent complex numbers Z₁ and Z₂ respectively on the argand plane
⇒ A = Z₁ = x₁ +i y₁ = 9 - 9 i and
B = Z₂ = x₂+ i y₂ = 10 -9 i
Let (x₁ , y₁) = ( 9, -9)
(x₂, y₂) = (10, -9)
Step(ii):-
The distance between the two points are
A B = [tex]\sqrt{(x_{2} - x_{1})^{2}+(y_{2} - y_{1})^{2} }[/tex]

Explain how you can solve the following scenario in two different ways. I owe my friend $16 and my mom owes me $25. how much money will I have after all is settled?
Answer:
$9
Step-by-step explanation:
Given I owe my friend $16 and my mom owes me $25
step 1-->take back money from mom
Mom gives back you $25
Now you have $25
Step 2: return the money you owe to friend
you owe $16
You have $25 and return $16
Thus , money you will have = money you have - money you return
money you have = $25 - $16 = $9
Thus, you will have $9 , after all is settled.
