1. Write an ordered pair to represent point G.
Answer:
n ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

Halla el MCM de 63 y 77
Respuesta:
693
Explicación:
Tenemos que dividir ambos dígitos hasta que lleguen a 1.
No importa si uno de los números no se puede dividir, pero se debe iniciar desde los números más bajos: 2, 3, 4, 5, 7...
Cómo no hay una mitad exacta, empezaremos con tercia y continuaremos dividiendo.
63 ; 77 | 3
21 ; 77 | 3
7 : 77 | 7
1 ; 11 | 11
1 ; 1
Ahora que llegamos hasta 1, el MCM es la multiplicación de los números por los que hemos dividido a los dígitos. Solo falta multiplicarlos.
3*3*7*11= 693
MCM = 693

Last year, Tim rode his bike a total of 50 3/8 miles. This year, he rode his bike a total of 258 3/4 miles. Which of the following explains about how much farther Tim rode his bike this year than last year? A. About 200 times farther; Subtract last year's distance from this year's distance to get 208 3/8.
Then round to the nearest hundred to get 200.
B. About 50 times farther; Round each distance to the nearest whole number.
Then multiply last year's distance by 50 to see that 259 is close to 50 × 5.
C. About 10 times farther; 258 is about 5 times 50, and 34 is 2 times 38, so multiply 5 × 2 to get 10.
D. About 5 times farther; Round each distance to the nearest whole number.
Then multiply last year's distance by 5 to see that 259 is close to 50 × 5.

You bought some stock, and then the stock price went down by 17.2% from the purchase price. By what percentage would the price have to increase for the investment to be back to the original value?
Step-by-step explanation:
Let's pick some easy numbers for illustration.
Let x equal our initial stock purchase, and, say it was $100.
x = $100
The problem says it's value dropped by 17.2%. If x = 100 is 100% of our stock value the 17.2% less is
[tex]x - 0.172x = 0.828x[/tex]
So now our stock is worth 0.828(100) = $82.80.
Now how much of an increase do we need to get back to $100.
[tex]100 - 82.80 = 17.20[/tex]
So our base is $82.80 because our stock price dropped, we want to know what percent increase is $17.20 of $82.80
[tex]17.20 \div 82.80 = 0.2077[/tex]
Or 20.77% increase to get back to original price.
To make this generic, since $100 is not supplied information, substitute x for 100 and 0.828x for the amount of money dropped.
x = original stock value
[tex]x - 0.828x [/tex]
Is the amount of value lost, and to be regained in the second part of the question.
To find out what portion the decrease is of the new value
[tex] \frac{(x - 0.828x)}{0.828x} = \frac{0.172x}{0.828x} = 0.2077 [/tex]
Or 20.77%

The weight of any cat in the local animal shelter is no more than 16 pounds. Let w be the weight in pounds of a cat in the shelter. Write inequality that means weight of no more than pounds .
Answer:
16 >_ w ( a line under >)
Step-by-step explanation:
Inequalities help us to compare two unequal expressions. The inequality that means the weight of a cat is no more than 16 pounds is 16>w.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
Given that the weight of any cat in the local animal shelter is no more than 16 pounds. Now, w be the weight in pounds of a cat in the shelter. Therefore, the inequality that means the weight of a cat is no more than 16 pounds is 16>w.

Step-by-step explanation:
we have to find x first
∠ABD= 90° because its a right angle
3x°=90°
divide by on both sides

It is 6.417.5 km from Indianapolis to London, England. The Flash can make this trip in 1
hour and 35 minutes. How fast is this in miles per hour?
Answer:
[tex]Speed = 2519.58 mph[/tex]
Step-by-step explanation:
Given
[tex]Distance = 6417.5km[/tex]
[tex]Time = 1\ hr: 35\ mins[/tex]
Required
Calculate the speed in miles per hour
Convert distance to miles
[tex]Distance = 6417.5km[/tex]
[tex]Distance = \frac{6417.5km}{1.609}\ miles[/tex]
[tex]Distance = 3988.50217526\ miles[/tex]
[tex]Time = 1\ hr: 35\ mins[/tex]
Divide minutes by 60
[tex]Time = 1\ hr + 35/60[/tex]
[tex]Time = 1\ hr + 0.583\ hr[/tex]
[tex]Time = 1.583hr[/tex]
The speed is:
[tex]Speed = Distance/Time[/tex]
[tex]Speed = 3988.50217526/1.583 mph[/tex]
[tex]Speed = 2519.58 mph[/tex]

Complementary angles
============================================================
Explanation:
The square marker indicates a 90 degree, or right angle.
The two smaller angles (3x and 75) both combine to the larger 90 degree angle. That's what it means when they say we have complementary angles.
Add up the smaller angles, set the sum equal to 90, and solve for x.
3x+75 = 90
3x+75-75 = 90-75 ....... subtracting 75 from both sides
3x = 15
3x/3 = 15/3 ..... divide both sides by 3
x = 5
---------------
If x = 5, then 3x = 3*5 = 15
Then we can see that 15+75 = 90 to help check our answer.

Step-by-step explanation:
A solar heating device can recharge (store heat) in a single sunny day enough to provide for the next two days. In other words, the only times that the solar heat must be augmented by some other heat source is when there are three or more consecutive cloudy days. During the heating season, a period of 120 days, the weather patterns are described by the following Markov chain:
Sunny Cloudy
Suuny 1/2 1/2
Cloudy 1/3 1/3
Using this information, construct another Markov chain which is capable of indicating when the solar heat must be augmented. Hint: Think carefully about your state definition.
Answer:
Step-by-step explanation:
Suppose the number of days is represented with the states(S) provided that a sunny day, with a maximum of three.
i.e.
S = (0, 1, 2, 3)
It implies that; if we assume that [tex]X_n=2[/tex], what this means is that today appears cloudy, then yesterday was cloudly as well while the day before yesterday was sunny.
