Answers
Answer:
[tex]n=5/2[/tex]
Step-by-step explanation:
We have the equation:
[tex]5^{2n-2}=125[/tex]
Notice that 125 is the same as 5³. So:
[tex]5^{2n-2}=5^3[/tex]
Since they have the same base, the exponents must be equal. Therefore:
[tex]2n-2=3[/tex]
Solve for n. Add 2 to both sides:
[tex]2n=5[/tex]
Divide both sides by 2:
[tex]n=5/2=2.5[/tex]
So, the value of n is 5/2.
And we're done!
Answer:
N = 2.5
Step-by-step explanation:
Ok, so try this.
125 is 5^3, right?
And in this equation, we have 5 to the power of 2n-2 is equal to 125.
You need to make sure that the exponent ends up as 3.
How would you do this?
Try substituting N for 3.
That's too big.
Try Substituting N for 2.
That's a bit too small.
What number is in between 2 and 3?
2.5 is.
N = 2.5
Check your work, and see if you came up with the same answer
Work:
2.5 x 2 = 5
5 - 3 = 2
5^3 = 125

The Bureau of Labor Statistics1 in the US tells us that, in 2010, the unemployment rate for high school graduates with no college degree is 9.7 % while the unemployment rate for college graduates with a bachelor’s degree is only 5.2 %. Find the difference in proportions of those unemployed between these two groups and give the correct notation for the difference, with a minus sign. Since the data come from the census, you can assume that the values are from a population rather than a sample. Use the correct notation for population proportions and use subscripts on the proportions to identify the two groups. Assume high school graduates with no college degree are group 1 and college graduates with a bachelor's degree are group 2. 1Thompson, D., ‘‘What’s More Expensive than College?
Answers
Answer:
The difference is [tex]p= 0.045[/tex]
Step-by-step explanation:
From the question we are told that
The proportion unemployment rate for high graduated is [tex] p_1 = 0.097[/tex]
The proportion unemployment rate for college graduate is [tex] p_2 = 0.052[/tex]
Generally the difference in proportions of those unemployed between these two groups is mathematically represented as
[tex]p= p_1 - p_2[/tex]
=> [tex]p= 0.097- 0.052[/tex]
=> [tex]p= 0.045[/tex]

if a ferry boat covers 28 miles in 4 hours how much distance will it cover in 12 hours?
Answers
Answer:
84 miles in 12 hour
Step-by-step explanation:
12/4 = 3
3*28=84
Answer:
84 miles.
Step-by-step explanation:
First, find the rate of miles travel per hour. It is given that the boat covers 28 miles in 4 hours. Simply divide 28 with 4:
28/4 = 7
The boat covers 7 miles per hour.
Now, multiply 12 hours with 7:
12 hours x 7 miles per hour = 84 miles per 12 hours.
84 miles is your answer.

Allie must sell at least 50 gift baskets for the band fund-raiser. She already sold 36 baskets. Write and solve an inequality to determine how many more baskets Allie must sell for the fund-raiser.
Answers
Answer:
36+x>=50
I might be wrong but here's my explanation.
Step-by-step explanation:
We first of all know that she MUST sell 50 or more baskets.
Knowing this, we know the inequality sign will be facing the x and the 36 as the baskets can be equal to 50 or greater than 50.
Now we have: 36+x>=50
The x is remaining baskets needed.
If you were to solve the inequality you would get x>=14

Which fractions have a decimal equivalent that is a repeating decimal 13 65, 141-47, 11-12 or 19-3
Answers
Answer:
Step-by-step explanation:
If you convert 13/65 to a decimal its 0.2, thats not repeating, if u convert 141/47 to a decimal its 3, so thats not repeating. If you convert 11/12 to a dec. its repeating 0.9166666666667 so yes its repetitive and 19/3 converted to a decimal is 6.333333333 its repetitive. 11/2 and 19/3 are the answers. Woohoo
Fractions 11 / 12 and 19 / 3 have the decimal equivalent which is a repeating decimal.
Given that,
Fraction, 13 / 65, 141 / 47, 11 / 12 or 19 / 3 are given.
We have to determine that fractions have a decimal equivalent that is a repeating decimal.
Recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.
Here,
13/65 = 0.2
141 / 47 = 3
11/ 12 = 0.9166666666......
19/3 = 6.333333333
So, from the above calculation, 11 / 12 and 19 / 3 have the repeating decimal.
Thus, Fractions 11 / 12 and 19 / 3 have the decimal equivalent which is a repeating decimal.

C 0.23 +0.23 +0.45
0.30+ 0.41 +0.23
Answers
Answer: C.

A. is .97
B. is 1.01
C. . is .91
D. is .94
So C. has the lowest value
The number which has the lowest value is 0.23 +0.23 +0.45, the correct option is C.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given;
A 0.30 +0.54 +0.13
B 0.10 +0.66 +0.25
C 0.23 +0.23 +0.45
0.30+ 0.41 +0.23
Now
A 0.30 +0.54 +0.13=0.97
B 0.10 +0.66 +0.25=1.01
C 0.23 +0.23 +0.45=0.91
0.30+ 0.41 +0.23=0.94
Therefore, the algebra with lowest value will be 0.23 +0.23 +0.45

can you please help me solve this 1/3(x+6)=1/2(x-3)
Answers
Answer:
The answer is X=21
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Simplify 1/3 and 1/2
It would look like [tex]\frac{(x+6)}{3} -\frac{(x-3)}{2}[/tex]
then[tex]\frac{21-x}{6}=0[/tex]
then mutiply 6 to each side and it will look like 21-x = 0
Last, subtract 21 from each side and it will be
21=x
