Answer:
(-2, 6)
Step-by-step explanation:
Since you want a 1 to 7 ratio, you want to divide the line into 2 parts, where one part has a length of 1 and the other has a length of 7. So the total length of the line is 8.
Start by looking at the difference in the X and Y coordinates.
X = | -4 - 12 | = | -16 | = 16
Y = | 7 - -1 | = | 8 | = 8
You could calculate the length of the line using pythagorian's theorem, but that's not needed. Simply use similar triangles. We have a right triangle with legs of length 16 and length 8. We want a similar triangle that is 1/8th as large (to get the desired 1 to 7 ratio). So divide both legs by 8, getting lengths of 16/8 = 2, and 8/8 = 1.
Now add those calculated offsets to point A.
A has an X coordinate of -4 and B has an X coordinate of 12 and the X coordinate for C must be between those limits. So calculate -4 + 2 = -2 to get the X coordinate for C.
The Y coordinate of A is 7 and the Y coordinate of B is -1. And since the Y coordinate must be between then, you have 7 - 1 = 6.
So the coordinates for C is (-2, 6)
Using every day knowledge which of the following statements is an if/then statement whose reverse is also correct.
A. if an ambulance has emergency lights on, then cars on the road pull over.
B. if the TV is unplugged, then the TV will not turn on.
C. if the wind is blowing, then the weather is chilly
D. if the light bulb was recently on, then the lightbulb is hot
B. if the TV is unplugged, then the TV will not turn on.
A conditional statement has two parts: hypothesis (if) and conclusion (then).
The converse is when we switch or interchange our hypothesis and conclusion.
So, we have given statements as:
A. if an ambulance has emergency lights on, then cars on the road pull over.
B. if the TV is unplugged, then the TV will not turn on.
C. if the wind is blowing, then the weather is chilly.
D. if the light bulb was recently on, then the lightbulb is hot.
If we see the converse statement of C.
If the tv does not turn on it’s unplugged.
So the statement is true in both the ways.

The sum of three consecutive integers is 180. What is the largest integer?
Answer:
61
Step-by-step explanation:
Here's a neat trick when you have an odd number of consecutive numbers.
Call the middle number k
Then the smaller number is k-1
The larger number is k + 1
The two ones will cancel.
k-1 + k + k-1 = 180
3k = 180
k = 180/3
k = 60
Therefore the largest number is k + 1 = 60 + 1 =61

Valleywood Golf course offers classes Monday through Saturday. The Saturday classes last 75 minutes. If they offered 705-minutes of classes last week, what was the maximum number of weekday classes?
Answer:
Step-by-step explanation:
To make the problem easier to solve, we will set it up as the equation of the length of time of each class times the number of classes equals the total amount of minutes. However, since we don't know the number of classes, we'll symbolize our two unknowns with two variables.
75x + 45y = 705
(75x + 45y)/15 = 705/15
5x + 3y = 47
y = (47-5x)/3
It looks like we can't simplify the equation any more, so now it is a matter of trial and error. The minimum number of Saturday classes means the maximum number of weekday classes. We first will test for the maximum by assuming there are no Saturday classes, then will work our way up until x is an integer.
If x = 0
(47-5(0))/3 = 47/3 = 15.6666
If x = 1
(47-5(1))/3 = 42/3 = 14
This works. Therefore, the maximum number of weekday classes is 14, or choice b.
How many 1-1 functions from a set with five elements to a set with 4 elements?
Answer:
The number is zero
Step-by-step explanation:
From the question we are told to state the number of on-to-one that exist from the set of 5 element to the set 4 element
Generally there are no one-to-one function from a set with a higher number of elements to a set with the lower number of elements
So the correct answer to the question is there are no one-to-one function from the set of 5 elements to the set of 4 elements

The cost of 1.00 Liters of gas is 26.9 cents. How many dollars will 12.0 gallons cost?
The cost of 12 gallons of gas will be 1221.80 cents.
It is given that 1 liter of gas cost 26.9 cents.
We have to calculate the cost of 12 gallons of gas.
What will be the cost of 10 pens if 1 pen costs 2 cent ?
The cost of 10 pens will be 10 × 2 = 20 cent.
As per the question ;
Cost of 1 liter of gas = 26.9 cent
∵ 1 gallon = 3.785 liters
So ,
The cost of 1 gallon of gas = 3.785 × 26.9
The cost of 12 gallons of gas will be ;
= 12 × 3.785 × 26.9
= 1221.80 cents
Thus , the cost of 12 gallons of gas will be 1221.80 cents.

Se tiene un conjunto de triángulos equiláteros, cuya medida de lados están en progresión geométrica cuya razón es 2. Si se ordenan los triángulos de acuerdo a su tamaño, se tiene que el primer triángulo mide un 1 cm de lado , ¿cuánto medirá el lado del vigésimo triángulo equilátero?¿cuánto medirá su perímetro?
Responder:
Explicación paso a paso:
Dado el conjunto de un triángulo equilátero con cada uno de sus lados en progresión geométrica, si el primer triángulo mide un lado de 1 cm y una razón común de 2 cm, para obtener el lado del triángulo 29, usaremos la fórmula para calcular el enésimo término de la progresión geométrica. expresado como;
Tn = ar ^ (n-1)
a es el primer término
n es el número de términos
r es la razón común.
Dados los siguientes parámetros
a = 1, r = 2 y n = 20 (ya que estamos buscando el lado del vigésimo triángulo)
Sustituyendo los parámetros dados en la fórmula para obtener el lado del triángulo 20, tendremos;
T20 = 1 (2) ^ 20-1
T20 = 1 (2) ^ 19
T20 = 2 ^ 19
T20 = 524,288 cm
Por lo tanto, la medida de la longitud de un lado del vigésimo triángulo equilátero es 524,288 cm.
Perímetro del vigésimo triángulo equilátero = 3 × 524,288 = 1,572,864cm
Tenga en cuenta que todos los lados de un triángulo equilátero son iguales.

A bag contains 8 green, 4 black and 6 yellow marbles. How could you use the complement to determine the probability of randomly selecting a green or black marble?
Answer:
12/18=2/3
Step-by-step explanation:
You should add up every marbles to find out how many marbles are in total. Then, you should add the green and black marbles. There are 4 black marbles, and 8 green marbles, which results 12 black+green marbles. Then you should make a fraction 12/18, because you are finding the probability of the green+black marbles out of the total marbles. If you simplify, you get 2/3.
The probability of randomly selecting a green or black marble is 12/18.
What is probability?Probability is the ratio that determines how likely an event is to occur from a set of possible events.
We can find the probability of randomly selecting a green or black marble as shown below:Total number of green marbles = 8
Total number of black marbles = 4
Total number of yellow marbles = 6
Total number of marbles = Total number of green marble + Total number of black marbles + Total number of yellow marbles = 18
P(selecting a green marble) = Total number of green marbles/Total number of marbles
= 8/18
P(selecting a black marble) = Total number of black marbles/Total number of marbles
= 4/18
P(selecting a green or black marble) = (Total number of green marbles + Total number of black marbles)/Total number of marbles
= (8 + 4)/18
= 12/18
Therefore, we have found the probability of randomly selecting a green or black marble to be 12/18.

Answer:
20.25
Explanation:
We first need to find the length of one side of the square. We can do this by dividing the area by 4 (27/4), since a square has four sides. You should get 6.75. Now you can multiply 6.75 by three since one side of the square is the same as one side of the triangle. Also, it is an equilateral triangle and all sides are the same. If you multiply correctly, you should get 20.25. Hope this helped!
Answer:
9 sqrt(3)
Step-by-step explanation:
Since the area of the square is 27 cm^2
A = s^2
27 = s^2
Take the square root of each side
sqrt(27) = s
sqrt(9) sqrt(3) = s
3 sqrt(3) =s
We know the the side length of the triangle is s
The perimeter of the triangle is
P =3s = 3 ( 3 sqrt(3))
= 9 sqrt(3)

Step-by-step explanation:
