The voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27/125 of a volt and it has been reduced three times. Write the voltage in exponential form, what was the original voltage in the circuit?
Answers
I belive this is the answer
x³ = 27/125; and
x = 3/5.
explanation:
Reducing the voltage 3 times would result in multiplying the unknown voltage, x, by itself 3 times; this gives us
x³.
The current voltage is 27/125; this gives us the equation
x³ = 27/125.
To solve this, take the cubed root of both sides:
∛(x³) = ∛(27/125)
x = (∛27)/(∛125)
x = (∛(3*3*3))/(∛(5*5*5))
x = 3/5

b. What does 0 mean in this situation?
Type your response in the space below.
Answers
Answer:
earned $30 means +30
spent $14 means -14 (he used the money to buy something meaning he loses some money)
spent $3.55 means -3.55 (again, he uses some money to buy something which means he loses this amount of money)
In this situation 0 means he either didnt gain/earn money or he spent all his money.

Answers
Answer:
B) No, supplementary angles are either of two angles whose sum is 180 degrees.
C) Yes, the triangles are congruent because the triangles have exactly the same size and shape
Step-by-step explanation:
B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.
C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.

Help me I am a stone when it comes to absolute value in problems—

Answers
Answer:
31.) you put a dot on one and go to the right
32.) you put a dot on ten and go to the left
Step-by-step explanation:
the absolute value part is honestly just to throw u off, it also helps if you read it aloud. so for example in # 31. is saying the absolute value of b minus 5 is greater or equal to 1, you could also think of it as any number is greater or equal to one. hope that helps!
when dealing with an absolute value expression, let's keep in mind that the expression once we remove the bars it has a ± version, so if the expression were say hmmm |a + b| = 25, if we remove the bars we really have a duet, namely ±(a + b) = 25, same if we had |a + b| > 25, then ±(a + b) > 25.
Tis noteworthy, that unlike "equalities", inequalities vary mainly on that, when we divide or multiply or exponentialize by a negative value, the inequality sign does a horizontal flip, it changes, so let's proceed
[tex]\boxed{31}\\\\ |b-5|\geqslant 1\implies \pm(b-5)\geqslant 1\implies \begin{cases} +(b-5)\geqslant 1\\ b\geqslant 6\\[-0.5em] \hrulefill\\ -(b-5)\geqslant 1\\ b-5\stackrel{\stackrel{notice}{\downarrow }}{\leqslant} -1\\ b \leqslant 4 \end{cases}~\hfill 6~~\leqslant ~~ b~~\leqslant ~~4[/tex]
[tex]\boxed{32}\\\\ |-2r|\leqslant 10\implies \pm(-2r)\leqslant 10\implies \begin{cases} +(-2r)\leqslant 10\\ -2r\leqslant 10\\ r\stackrel{\stackrel{notice}{\downarrow }}{\geqslant} \cfrac{10}{-2}\\\\ r\geqslant -5\\[-0.5em] \hrulefill\\ -(-2r) \leqslant 10\\ 2r \leqslant 10\\ r\leqslant \cfrac{10}{2}\\\\ r \leqslant 5 \end{cases}~\hfill -5~~\leqslant~~ r ~~\leqslant~~5[/tex]

Explanation:
The volume of a rectangular prism (R):
length x width x height
Replacing with the values given and solving for v(Volume)
V(R) = 4x 2 x 1
V(R) = 8m3
Volume of a triangular prism (T): base area X
height
Base area = 1/2 x base × height (of the triangular base)
A = 1/2 x1x 3.5 = 1.75m2
Back with the volume formula:
V (T)= Ax h= 1.75 x 2 = 3.5m3
Adding both volumes:
8 +3.5 = 11.5 m3

hope it helps...!!!
So Kate has to have at least three brothers because mike has the same amount of sisters as brothers and Kate is an extra sister,
So mike has three sisters and Kate has two sisters because she is a sister and two times two is four, so mike has three brothers, but there fr four boys in total
So Kate has two sisters and four brothers (mikes brothers+1)
Mike has three brothers and three sisters (Kate’s sisters plus one)
