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
Answer: 98.6 - x ≥ 2 or x - 98.6 ≥ 2
Step-by-step explanation:
Since, the normal temperature = 98.6° F
Also, the temperature that differs from normal by at least 2°F is considered unhealthy.
If the temperature is x degree F,
Then, we have two conditions,
Condition 1 : x > 98.6,
The difference between 98.6 and x = x - 98.6
Then the inequality be,
x - 98.6 ≥ 2
Condition 2 : x < 98.6
The difference between 98.6 and x = 98.6 - x
Then the inequality be,
98.6 - x ≥ 2
A bag has 5 red marbles, 6 blue marbles and 4 black marbles
so total no. of marbles = 5 + 6 + 4 = 15
now probability of picking a black marble = 4/15
after replacement again probability of picking black marble is 4/15
it is given that black marble is picked two times
so probability of picking black marble two times or picking , replacing , and then picking is 4/15*4/15 = 16/225
Answer:
y(x)=12*(5)^x
Step-by-step explanation:
y=ab^x, y(0)=12. 12=a.
y=12*b^x, y(2)=300. 12*b^2=300. b^2=25. b=5
The question is asking to states the definition of the term "how many" in math, base on the question and in my further research, the term is use as a count in every variables and situations. I hope you re satisfied with my answer and feel free to ask for more
