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
Step-by-step explanation:
p(x)+p(x+3)=10x-7 find p(3)
Answer:
Simplify each term.
Px+px+3p=10x−7
Move all terms not containing P to the right side of the equation.
Px=10x−7−px−3p
Divide each term by x and simplify.
P=10−7/x−p−3p/x
Step-by-step explanation:
La propiedad del producto cero indica que si la multiplicación de dos valores es igual a cero, se puede decir que alguno o ambos valores el igual a cero PORQUE Un producto de factores es cero si y solo si ,uno o más de los factores es cero.

Answer: 5x^2+3x+1
Step-by-step explanation:
Solving for (f+g)(x) add both functions so
(3x^2+4x)+(2x^2-x+1)
Add like terms
3x^2+2x^2=5x^2
4x+-x=3x
+1
Add terms
5x^2+3x+1
Jackie had a puzzle book that contains a total of 70 puzzles she has completed 2/5 of the puzzles in the book if Jackie completes 18 more puzzles what is the total number of puzzles that she will have completed in the book
Answer: 46 puzzles
Step-by-step explanation:
There are 70 puzzles in total in the book.
Jackie has completed / of those puzzles. In whole numbers that is:
= 2 /5 * 70
= 28 puzzles
She then completes 18 more puzzles.
Total that she has completed is:
= 28 + 18
= 46 puzzles

Write an inequality to represent 7 less than the product of a number, n, and 1/6 is at most 45."
Please help me, I need this right away!!!!
Answer:
The inequality to represent “7 less than the product of a number, n, and 1/6 is at most 45” is:
[tex]\frac{n}{6} -7\leq 45[/tex]
Solution:
Let the number be "n"
From given,
7 less than a product of a number n and 1/6 is at most 45
At most means "less than or equal to"
Therefore, inequality is framed as:
[tex]( n x \frac{1}{6}) -7 \leq 45[/tex]
Thus, inequality is:
[tex]\frac{n}{6} -7\leq 45[/tex]
Solve the inequality:
Add 7 to both sides
[tex]\frac{n}{6} -7 + 7\leq 45 + 7\\simplify\\\frac{n}{6} \leq 52[/tex]
Multiply both sides by 6
[tex]\frac{6n}{6} \leq 52 multiply 6[/tex]
simplify
[tex]n\leq 312[/tex]
Thus the inequality is solved.
hope it help :)

Answer:
y = -7
Step-by-step explanation:
5x+8y=29
5(17)+8y=29 (simplify by multiplying)
85+8y=29 (subtract 85 from both sides)
8y= -56 (divide both sides by 8y)
y = -7

7. 136°
8. 44°
Step-by-step explanation:
i don't know english very well so i don't knoe what transplant is but i think i got it right with my logic
Answer:
m∠1 = 136°
m∠2 = 44°
m∠3 = 136°
m∠4 = 44°
m∠5 = 136°
m∠6 = 44°
m∠7 = 136°
Step-by-step explanation:
Corresponding angles, like m∠1 and m∠5, need to equal each other.
m∠1 and m∠3 are the same
m∠3 and m∠2 need to be added together to equal 180

A circle with radius of \greenD{1\,\text{cm}}1cmstart color #1fab54, 1, start text, c, m, end text, end color #1fab54 sits inside a \blueD{3\,\text{cm} \times 3\,\text{cm}}3cm×3cmstart color #11accd, 3, start text, c, m, end text, times, 3, start text, c, m, end text, end color #11accd rectangle. What is the area of the shaded region?
Answer:
5.86cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the circle
Area of rectangle = Length * Width
Area of rectangle = 3cm * 3cm
Area of rectangle = 9cm²
Area of the circle = πr²
Given radius r = 1cm
Area of the circle = 3.14(1)²
Area of the circle = 3.14cm²
Area of the shaded region = 9 - 3.14
Area of the shaded region = 5.86cm²
Answer:
5.86cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the circle
Area of rectangle = Length * Width
Area of rectangle = 3cm * 3cm
Area of rectangle = 9cm²
Area of the circle = πr²
Given radius r = 1cm
Area of the circle = 3.14(1)²
Area of the circle = 3.14cm²
Area of the shaded region = 9 - 3.14
Area of the shaded region = 5.86cm²

Mike 24 coins in nices and dimes they are valued at $2.05. how many DIMES does he have?
Answer: He has 8 dimes
Step-by-step explanation:
Answer:
17 dimes
7 nickels
Step-by-step explanation:
n = number of nickels
d = number of dimes
0.10d + 0.05n = 2.05
n + d = 24, n = 24 - d
substitute for n:
0.10d + 0.05(24 - d) = 2.05
simplify:
0.10d + 1.20 - 0.05d = 2.05
0.05d = 0.85
d = 17
n = 24-17 = 7

Which inequality represents "six times a number is less than negative thirty-nine and three-quarters"? 6x > –39Three-fourths 6 + x > -39 Three-fourths 6x < -39Three-fourths 6 x less-than-or-equal-to negative 39 and three-fourths
Given:
The phrase is "six times a number is less than negative thirty-nine and three-quarters".
To find:
The inequality represented by the given phrase.
Solution:
Let x be the unknown number.
Six times a number is "6x".
Less than is "<".
Negative thirty-nine and three-quarters is "[tex]-39\dfrac{3}{4}[/tex]".
So, six times a number is less than negative thirty-nine and three-quarters is:
[tex]6x<-39\dfrac{3}{4}[/tex]
Therefore, the correct option is C.
Answer:
"six times a number is less than negative thirty-nine and three-quarters".
Step-by-step explanation:
