Answer:
Las propuestas correctas son;
a) Voltímetro de CA Mide el valor medio
La magnitud del voltaje de corriente alterna varía periódicamente con el tiempo, dentro de un rango dado
El voltímetro de CA proporciona la lectura y, por lo tanto, mide el valor medio del voltaje, el voltaje pico o el R.M.S. valor de la tensión
b) El voltímetro de CC mide el valor máximo
Los valores de voltaje de un circuito de corriente de CC se fijan con el tiempo y, por lo tanto, el voltímetro de CC mide los voltajes máximos en el circuito.
c) El amperímetro de CA mide el valor medio
Similar a la medición de voltaje de CA, el amperímetro de CA mide el valor de corriente medio
d) El A.C. mide el valor efectivo
La raíz cuadrada media o R.M.S. valor es el valor medido por un R.M.S. Medidor de A.C.
e) El D.C. se conecta en paralelo
Todos los voltímetros se colocan en paralelo con el circuito desde el que se va a medir el voltaje.
Sin embargo, un amperímetro de CC está conectado en serie

Write an equation of a line in slope intercept form that passes through (6,5) 1 poi
and is parallel to y =-X+4 *
Answer:
y = -x + 11
Step-by-step explanation:
The slope of the line y = -x + 4 is -1.
So the slope of our line is also -1 ( because they are parallel).
First use the point-slope form of the equation of a line:
y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line.
Here m = -1 and (x1, y1) = (6, 5).
So we have:
y - 5 = -1(x - 6)
y - 5 = -x + 6
y = -x + 11 <------ Slope intercept form.

Answer:
f(x) = 3x³ +6x² -3x -6
Step-by-step explanation:
Each x-intercept (x=p) gives rise to a factor (x-p), so the factored form of the function is ...
f(x) = a(x -(-2))(x -(-1))(x -1)
The value of 'a' is chosen to make the y-intercept match that shown. The function just written has ...
f(0) = -6 = a(2)(1)(-1)
-6 = -2a
a = 3 . . . . . divide by -2
So, the function in factored form is ...
f(x) = 3(x +2)(x +1)(x -1)
Expanded, this is ...
f(x) = 3x³ +6x² -3x -6

Kaley reads 6 graphic nwels fewer than Safara.
Daniel reads 3 times as many as Kaley.
Daniel reads 30 graphic novels.
a. How many graphic novels does Safara read?
Show your work.
Answer: 16
Step-by-step explanation:
We first find out the number of graphic novels that Kaley reads, we set the number as k.
3k = 30
k = 10
Then Kaley reads 6 graphic novels fewer than Safara, which means that we plus 6 to the number of graphic novels that Kaley read,
k + 6 = 10 + 6 =16
Safara read 84 graphic novels.
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations. The fundamental ideas in number theory, measurement, and computation are frequently referred to as arithmetic (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).
As per the given data:
Kaley reads 6 graphic novels fewer than Safara ...(i)
Daniel reads 3 times as many as Kaley ...(ii)
Graphic novels Daniel read = 30
Kaley read = 3 × 30 = 90 novels {from statement (ii)}
Safara read = 90 - 6 = 84 novels {from statement (i)}
Hence, Safara read 84 graphic novels.

Lashawna is making jewelry to sell at a craft fair. On Monday, she makes 12 bracelets. On Tuesday, she works an additional 2.5 hours and has a total of 22 bracelets. Determine the time it takes Lashawna to make one bracelet
Answer:
ok, so she made 10 bracelets in 2.5 hours. 22-12= 10
2.5 ÷10= .25 hours per bracelet
an hour is 60 minutes, so .25 x60= 15 minutes per bracelet
8 6/7 =
i want it in fraction form and in the smallest form.
Answer:
[tex]8\frac{6}{7}[/tex] as an improper fraction is [tex]\frac{62}{7\\}[/tex]
[tex]8\frac{6}{7}[/tex] in simplest form is [tex]8 \frac{6}{7\\}[/tex]
Step-by-step explanation:
To find the improper fraction of 8 6/7 is:
Multiply the denominator of the fraction by the whole number, 8. This gives you 56. Now, add the 56 with the numerator of the fraction. This gives you 62 as a sum. So, the improper fraction is 62/7.
You cannot simplify 8 6/7 because it is in simplest form.

What is length of PR
m PZR is 2/3 pie radius
Answer:
Option (4)
Step-by-step explanation:
m(∠PZR) = [tex]\frac{2}{3}\pi[/tex]
Radius of the circle = 8
Since, length of an arc = [tex]\frac{\theta}{2\pi }(2\pi r)[/tex]
Here, θ = Central angle in radians
From the given formula,
m(arc PR) = [tex]\frac{\frac{2}{3}\pi}{2\pi }(2\pi \times 8)[/tex]
= [tex]\frac{2}{6}(16\pi )[/tex]
= [tex]\frac{16}{3}\pi[/tex]
Therefore, Option (4) will be the correct option.

12.6% of
RI 149 390bn
Answer: RI 18,823.14
Step-by-step explanation:
I guess that we want to find the 12.6% of Rl 149,390
First, we assume that Rl 149,390 is the 100%
Then we can write an equation like:
Rl 149,390 = 100%
Then if the amount X is the 12.6%, we also have the equation:
X = 12.6%
Then we have the two equations:
X = 12.6%
Rl 149,390 = 100%
If we take the quotient between these two equations we get:
(X/Rl 149,390) = (12.6%/100%)
Solving this for X we get:
X = (12.6%/100%)*(Rl 149,390) = RI 18,823.14

A triangle has side lengths of 14 cm and 7 cm. Which could be the value of the third side, 22 cm or 20 cm?
Answer:
Undefined, it can be 20 cm, 22 cm or any value.A triangle has no limitations for any of each three sides.
Step-by-step explanation:
How it works? The triangles have no limits on their sides, but by their angles. Each triangle sums 180 degrees at the inner angles. If you don't have specific values for the angles it is not necessary to get some values for the third side. It could be 1, 2, .... or even 1000.
a person types 360 words in 4 minutes how much times does he take to types 900 words?
Answer:
10

Answer: 1. 18600000000 2. 645000
Step-by-step explanation:
62000000 x 300 = 18600000000
The area of Rhode Island is 1500. The area of Alaska land is a little more than 430.
1500 x 430 = 645000.
(I not sure if 645000 is the correct number, but that’s what I got).
