A una reunión asistieron tres amigos: Manuel, Hugo y Coco; y tres damas: Pamela, Nancy y Susan. Terminada la actividad, cada uno de los muchachos salió acompañado por una dama. Hugo salió con la amiga de Nancy. Pamela, que no simpatiza con Nancy, salió antes que Manuel.
Answer:
Hugo salió con Susan, Coco salió con Pamela y Manuel salió con Nancy.
Step-by-step explanation:
Dado que a una reunión asistieron tres amigos: Manuel, Hugo y Coco; y tres damas: Pamela, Nancy y Susan, y terminada la actividad, cada uno de los muchachos salió acompañado por una dama, y Hugo salió con la amiga de Nancy, mientras que Pamela, que no simpatiza con Nancy, salió antes que Manuel, para determinar con quién salió cada persona debemos realizar el siguiente razonamiento lógico:
Hugo = Amiga de Nancy (no es Pamela) = Susan
Pamela = Sale antes que Manuel (no sale con Hugo) = Coco
Nancy = Manuel
Por lo tanto, Hugo salió con Susan, Coco salió con Pamela y Manuel salió con Nancy.

Answer:
17.98
Step-by-step explanation:
We can use the sum of a finite geometric series formula(in the picture). We can start by plugging in what we have. As of now, we have the first term, 12 and by dividing a term by a previous term, we can tell that the common ratio, r is 1/3. Lastly, we can say that n is equal to 6, because we are looking for the sum of the first 6 terms. After substituting we get:
[tex]\frac{12 - 12*(\frac{1}{3})^6}{1-\frac{1}{3} }[/tex]
We can start by simplifying:
[tex]\frac{12-12(\frac{1}{729}) }{\frac{2}{3} }[/tex]
[tex]\frac{\frac{2916}{243} -\frac{4}{243} }{\frac{2}{3} }[/tex]
[tex]\frac{\frac{2912}{243} }{\frac{2}{3} }[/tex]
[tex]\frac{2912}{243}*\frac{3}{2}[/tex]
[tex]\frac{1456}{81}[/tex]
17.975308642
This can be rounded to 17.98
Answer:
17.98Step-by-step explanation:
Given:
a₁ = 12r = 1/3n = 6Find the sum:
Sₙ = 12(1 - (1/3)⁶)/(1 - 1/3) = 12(1 - 1/729) / (2/3) = 18(728/729) = 17.98 roundedA family on vacation records the time in hours) and the distance (in miles) that they travel. The data are shown in the scatter plot below.

Time (hours)
Based on the scatter plot, the family travels miles in the first 3.5 hours.
If you answer with a link I will report you and get your account blocked
Answer:
In the first 3.5 hours, the family travelled 175 miles.
Step-by-step explanation:
We have the table:
time (hours) distance ( miles)
0 0
1 50
2 100
3 150
4 200
5 250
6 300
7 350
8 400
9 450
This seems like a linear relationship, let's write the general line:
y = a*x + b
That represents this situation, y is the distance in miles and x is the time in hours.
In the line equation, a represents the slope and b the y-intercept.
And if the line passes through the points (x₁, y₁) and (x₂, y₂), then the slope of the line is:
a = (y₂ - y₁)/(x₂ - x₁)
In this case we have a lot of points for the line, we can use any pair we want (we actually should use a few different pairs to see that the slope is always the same)
So if we use the first two (0, 0) and (1, 50)
the slope is:
a = (50 - 0)/(1 - 0) = 50
Now, if we use the third and fifth points (4, 200) and (5, 250) now the slope is:
a = (250 - 200)/(5 - 4) = 50/1 = 50
So we can conclude that the slope of the equation is a = 50
Then the equation is something like:
y = 50*x + b
To find the value of b, we can use any of the points of the line, for example (0, 0)
This means that when x = 0, y also must be 0, then:
0 = 50*0 + b
0 = b
Then the equation is:
y = 50*x
Now, to answer how many miles the family travelled in the first 3.5 hours, we just need to replace x by 3.5 in the equation:
y = 50*3.5 = 175
In the first 3.5 hours, the family travelled 175 miles.
A teacher asked four students to estimate the length of a grain of rice. Jack answered 4.5 x 10^-3 kilometer, Lilly answered 4.5 x 10^-3meter, Diego answered 4.5 x 10^-3vcentimeter, and Willa answered 4.5 x 10^-3 millimeter. Who gave the best answer
Answer:
Lilly
Step-by-step explanation:
According to the literature, the length of a medium grain rice is between 5.3 and 5.9 mm. Let's take the average (5.6 mm) and convert it to meters to compare it with the estimations. We will use the conversion factor 1 m = 1000 mm.
5.6 mm × 1 m/1000 mm = 5.6 × 10⁻³ m
Jack answered 4.5 × 10⁻³ kilometers. We will convert it to meters using the conversion factor 1 km = 1000 m.
4.5 × 10⁻³ km × 1000 m/1 km = 4.5 m
Lilly answered 4.5 × 10⁻³ meters.
Diego answered 4.5 × 10⁻³ centimeters. We will convert it to meters using the conversion factor 1 m = 100 cm.
4.5 × 10⁻³ cm × 1 m/100 cm = 4.5 × 10⁻⁵ m
Willa answered 4.5 × 10⁻³ millimeters. We will convert it to meters using the conversion factor 1 m = 1000 mm.
4.5 × 10⁻³ mm × 1 m/1000 mm = 4.5 × 10⁻⁶ m
As we can see, Lilly gave the best answer (same order of magnitude).

Which one is equivalent? Ez points
Answer: B: -4 by -4 by -4
Step-by-step explanation: When a number is to be used with a negative exponent, the number is to be multiplied by however many times the number says to multiply it, and whether the exponent is positive or negative determines the numbers being multiplied, whether they should be negative or positive. (Sorry, I'm not good at wording this, I'll provide an example below.);
4^-3 means that you multiply four three times, but the exponent is also negative, so it would make each of the base numbers negative.

Name the angle and the intercepted arc.
Answer:
The angle formed is ∠LMK and the intercepted arc is LK.
Step-by-step explanation:
The given figure shows a circle of radius M. L and K are other points on the circle.
The distance from the center of the circle to a point on the circle is called radius.
LM and MK are the radius of the circle or
LM = MK
The angle formed is ∠LMK.
The intercepted arc is LK.

Answer:
C
Step-by-step explanation:
ABCD is a rectangle so BC = AD
Since opposite side of a rectangle are equal in length, the side BC is equals to AD. Therefore, side BCis equals to 18 units.
Properties of a rectangleOpposite sides are equalOpposite sides of a rectangle are parallelAll the angles of a rectangle are equals to 90 degrees.The diagonals of a rectangle are equal in length.The diagonal bisect each other at there point of intersection.
Since opposite sides are equal in length. Therefore,
AD ≅ BC
AB ≅ CD

Answer:
Y remains unchanged because y is still 7.
Suma masurilor a doua unghiuri este egala cu 180(de grade). Determinati masura fiecarui unghi stiind ca unul dintre unghiuri are masura egala cu 20% din masura celuilalt unghi
Answer:
150 grados
30 grados
Step-by-step explanation:
Sea x la medida del primer ángulo
Sea la medida del segundo ángulo y
Según la pregunta;
x + y = 180 -------- (1)
De la segunda oración;
x = 0,2 años -------- (2)
Sustituyendo (2) en (1)
0,2 años + y = 180
1,2 años = 180
y = 180 / 1,2
y = 150 grados
Pero;
x = 0,2 años
Entonces
x = 0,2 (150)
x = 30 grados
Por eso;
y = 150 grados
x = 30 grados

A cylinder has a radius of 5x + 4 and a height of 2x + 5. Which polynomial in standard form best describes the total volume of the cylinder? Use the formula v=πr²h for the volume of a cylinder
Answer:
Step-by-step explanation:
Volume = pi·(r^2)*h
r = radius = (5x+4)
h = height = (2x+5)
Volume = pi·(r^2)
Volume = pi·(5x+4)^2*(2x+8)
Volume = pi·(25x^2+40x+16)*(2x+8)
Volume = pi·(50x^2+80x+32+200x^2+32x+128)
Volume = pi·(250x^2+112x+160)
