Answer:
x = 25
Step-by-step explanation:
The proportion can be written using fractions and solved for x in the usual way.
[tex]\dfrac{125}{x}=\dfrac{x^2}{125}\\\\125^2=x^3\qquad\text{multiply by 125x}\\\\x=\sqrt[3]{125^2}=\sqrt[3]{5^6}=5^2\qquad\text{take the cube root}\\\\\boxed{x=25}[/tex]
what is the sum of 7x/ x^2 - 4 and 2 / x + 2?
The sum of two given algebraic expressions is (9x-4)/(x²-4). Therefore, option C is the correct answer.
What is addition of algebraic expression?Addition of Algebraic Expressions is the process of collecting like terms and adding them. Identify and add the coefficients of like terms and sum them to find the final expression of given problems.
The given algebraic expressions are 7x/x²-4 and 2/x+2
Here, 7x/x²-4 can be written as 7x/(x+2)(x-2)
Now, 7x/x²-4 + 2/x+2
= 7x/(x+2)(x-2) + 2/x+2
= (7x+2(x-2))/(x+2)(x-2)
= (7x+2x-4)/(x²-4)
= (9x-4)/(x²-4)
Therefore, option C is the correct answer.

A 6 sided die and a coin is tossed, how many different possible outcomes are there? Need help ASAP!!
Answer:
the answer is 12
Step-by-step explanation:
you toss the dice and coin let’s say it lands on 2 and heads there is one possibility. there is only 6 sides to the dice and 2 sides to a coin. 6 x 2 = 12.
Answer: coin = 26 sided die = 62 × 6 = 12
Step-by-step explanation: When you flip a coin there are two possible outcomes (heads or tails) and when you roll a die there are six outcomes(1 to 6). Putting these together means you have a total of 2×6=12 outcomes. The answer would be 12. Hope that helps!!

Answer:
1/32
Step-by-step explanation:
1st step: 1/4 divided by 8, which is 1/4 divided by 8/1
Then for the 2nd step, you have to find the reciprocal of the 2nd fraction, so you just reverse it
2nd step: 1/4 X 1/8
3rd step. 1X1/4X8 = 1/32
You can also think of it like this. He started with 4 pieces. Each piece was then divided into 8 parts. So 8X4=32 is the total number of pieces. He's only eating 1 of those, so he's only eating 1/32

what is the slope intercept of the equation y = -x + 12?
Answer: b) slope: -1, y-intercept 12
Step-by-step explanation:
The equation here is in slope-intercept form (y=mx+b)
In slope-intercept form m is the slope and b is the y-intercept
m=-1 and b=12 so the answer is b
slope: -1, y-intercept: 12
Solution:The given equation is written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept.You can quickly identify the slope & y-intercept of a line whose equation is in slope-intercept form.The slope is the coefficient of x (the number before x) and the y-intercept is a constant added to/subtracted from the slope.Therefore, m is equivalent to -1, and b is equivalent to 12.Hope it helps.

Answer for 1st question:
The answer is A. 4/20
Step-by-step explanation:
The probability of landing on a vowel would be 2/5.
The probability of landing on an even number would be 2/4.
Now we just need to solve the probability of landing on a vowel and an even number.
2/5 x 2/4 = 4/20.
Thereore, the probability of landing on a vowel and an even number is 4/20.
Answer for 2nd question:
The answer is B. 1/20
Step-by-step explanation:
The probability of landing on a C would be 1/5.
The probability of landing on a 4 would be 1/4.
Again, we just need to solve the probability of landing on a C and a 4.
1/5 x 1/4 = 1/20.
Therefore, the probability of landing a C and a 4 is 1/20.

Answer:
8 bracelets
Step-by-step explanation:
Each time when we we cut the ribbon for making a ribbon, the length will be reduced. So, repeated subtraction is division.
To find the number of bracelets, divide the total length of the ribbon by the length required for making a bracelet.
Fraction division:
Use KCF method
Step1: Keep the first fraction
Step2: Change division to multiplication
Step3: Flip the second fraction
Number of bracelets = total length ÷ length required for making a bracelet.
[tex]= 5\dfrac{1}{3} \div \dfrac{2}{3}\\\\= \dfrac{16}{3} \div \dfrac{2}{3}\\\\= \dfrac{16}{3}*\dfrac{3}{2}\\\\= 8[/tex]

Which equation accurately represents this statement? Select three options.
Negative 3 less than 4.9 times a number, x, is the same as 12.8.
Negative 3 minus 4.9 x = 12.8
4.9 x minus (negative 3) = 12.8
3 + 4.9 x = 12.8
(4.9 minus 3) x = 12.8
12.8 = 4.9 x + 3
Answer:
See below ~
Step-by-step explanation:
Writing the equation
Negative 3 less than 4.9 times a number, x, is the same as 12.8⇒ 4.9x - (-3) = 12.8⇒ 4.9x + 3 = 12.8Solutions

Step-by-step explanation:
When reducing fractions to their simplest equivalent, we need to divide the numerator and denominator by their highest common factor.
Factors of 20: 1, 2, 4, 5, 10, 20
Factors of 32, 1, 2, 4, 8, 16, 32

A recent survey showed that 91 full-time employees out of a sample of 500 did not use all of their vacation days last year. However, 105 of those studied expressed a desire for more vacation time. Based on this sample, if a full-time employee is chosen at random, what is the probability that he or she is content with the vacation allowance? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth
Using it's concept, it is found that there is a 0.79 = 79% probability that he or she is content with the vacation allowance.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, 500 - 105 = 395 out of 500 employees are content with the vacation allowance, hence:
p = 395/500 = 0.79.
There is a 0.79 = 79% probability that he or she is content with the vacation allowance.
