Solve log812 = x – 2 . Round your answer to four decimal places.
Answer:
[tex]x=3.1950[/tex]
Step-by-step explanation:
Given:
The equation to solve is given as:
[tex]\log_8 12=x-2[/tex]
In order to solve this, we use the base change formula of logarithms.
The base change formula is given as:
[tex]\log_a b=\frac{\log b}{\log a}[/tex]
Therefore, the equation can be rewritten as:
[tex]\frac{\log 12}{\log 8}=x-2[/tex]
Adding 2 on both the sides, we get:
[tex]x=2+\frac{\log 12}{\log 8}[/tex]
Now, we know that, [tex]\log 12=1.07918\ and\ \log 8=0.9031[/tex]
Plug in these values and solve for 'x'. This gives,
[tex]x=2+\frac{1.07918}{0.9031}\\\\x=2+1.19497=3.19497\approx3.1950[/tex]
Therefore, the value of 'x' is 3.1950 rounded to four decimal places.

A.) 12.5
B.) 10
C.) 13
D.) 9.7
Step-by-step explanation:
In given figure,
Base (b) = 11 and Angle = 28°
To find, the value of x = ?
We know that,
[tex]\cos A=\dfrac{b}{h}[/tex]
Where, h is the hypotaneous = x
⇒ [tex]\cos 28=\dfrac{11}{x}[/tex]
⇒ [tex]x=\dfrac{11}{\cos 28}[/tex]
The value of [tex]\cos 28[/tex] = 0.8829
⇒ x = [tex]\dfrac{11}{0.8829}[/tex]
⇒ x = 12.458
⇒ x ≈ 12.5
∴ The value of x ≈ 12.5

Answer:
It takes May 6 minutes and 24 seconds to run 4 laps and 1 minute and 36 seconds per lap
Statement and question:
May runs around a 400-meter track at a constant speed of 250 meters per minute. How many minutes does it take May to complete 4 laps of the track?
Source:
Previous question that can be found at brainly
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Speed of May = 250 meters per minute
Length of the track = 400 meters
2. How many minutes does it take May to complete 4 laps of the track?
Let's answer the question calculating the total distance and the time it took Mary to run around the track, this way:
Total distance = 4 * 400 = 1,600 meters
Time it takes May to run 1,600 meters = 1,600/250
Time it takes May to run 1,600 meters = 6.4 minutes
6.4 minutes = 6 minutes + 0.4 * 60 seconds = 6 minutes and 24 seconds
Time it takes May to run one lap = 6.4/4 = 1.6
1.6 minutes = 1 minute + 0.6 * 60 seconds = 1 minute and 36 seconds

If X = 16 feet and Y = 8 feet, what is the area of the figure above ? Use 3.14 for pi .
A. 153.12 feet^2
B. 178.24 feet^2
C. 228.48 feet^2
D. 52.56 feet^2
Answer:
A
Step-by-step explanation:
You can probably figure out the rectangle of 16 by 8 so no explaining there. 16×8=128. You know that diameter of the cirkel is equal to y so 8. The diameter of a cirkel is two times its radius. so 8=2r. r=4. The area of a cirkel is calculated by the formula \pi×r^2. Fill in r=4 in \pi×r^2 gives us \pi×4^2=16\pi. You only have half of the cirkel so 16\pi/2=8\pi. 128+8\pi=153.12 which is A.
What value of b will cause the system to have an infinite number of solutions? Y=6x+b -3x+1/2y=-3
Answer:
b = -6
Step-by-step explanation:
Given:
y=6x+b ----- (eq 1)
and
-3x+1/2y=-3 (Rearrange this equation to look likes eq (1) , add -3x to both sides)
(1/2) y = 3x - 3 (multiply both sides by 2)
y = 2(3x -3) (distribute the 2 into parentheses)
y = 6x - 6 -----(eq 2)
Recall that a system of equations will have an infinite number of solutions if both equations are the same line. (i.e they have the same slope and y intercept)
In our case, if you compare eq 1 and eq 2, the way to make both equations the same line is if b = -6. (this is the answer)
If a 16 fl oz bottle of water costs $1.50, and a gallon of gasoline costs $3.50. Which Costs more?
PLEASE MARK BRAINLIEST!
Answer:
Let's find out!
Step-by-step explanation:
**There is 128 fl oz in a gallon**
To solve, we will try and find the unit rate of 1 fl oz of both the cost of the water and the cost of the gasoline. A unit rate is when the denominator of a fraction is 1, showing how much of something equals 1 of the denominator. For example, if the cost was $1 for 1 fl oz, the cost of a gallon of gasoline would be $128.
[tex]\frac{cost(dollars)}{fl|oz}[/tex]
[tex]\frac{1.50}{16}[/tex] ÷ [tex]\frac{16}{16} = \frac{0.09375}{1} = \frac{0.09}{1}[/tex]
[tex]\frac{3.50}{16}[/tex] ÷ [tex]\frac{128}{128} = \frac{0.02734375}{1} = \frac{0.03}{1}[/tex]
For every 1 fl oz of water, it will cost $0.09
For every 1 fl oz of gasoline, it will cost $0.03
Which costs more?
Your answer is the water.I hope this helps!

there are two numbers which add up to be 29. If one number is one more than the other find the two numbers
Final answer:
The two numbers that add up to 29, where one number is one more than the other, are 14 and 15. The equation 2x + 1 = 29 helped determine that the smaller number is 14, and adding one gives us the larger number, 15.
Explanation:
The two numbers in question are those that sum up to 29, and one number is one more than the other. Let's denote the smaller number as x, which makes the larger number x + 1 because it's one more than the smaller one. Setting up the equation based on the information given, we have:
x + (x + 1) = 29
Combining like terms gives us:
2x + 1 = 29
To find the value of x, we subtract 1 from both sides:
2x = 28
And then divide by 2:
x = 14
Therefore, the smaller number is 14, and the larger number, being one more than 14, is 15.

Suppose that ? Is an angle with csc(?)=-12/5 and ? Is not in the third quadrant. Compute the exact value of Tan(?). You don’t have to rationalize the denominator.
I think the answer is -5/rad119, but I’m not sure
Answer:
[tex]tan(\theta)=-\frac{5}{\sqrt{119}}[/tex]
Step-by-step explanation:
The correct question is
Suppose that ∅ Is an angle with csc(∅)=-12/5 and ∅ Is not in the third quadrant. Compute the exact value of Tan(∅).
∅ Is not in the third quadrant
If csc(∅) is negative the angle lie in the III Quadrant or in the IV Quadrant
∅ Is not in the third quadrant ----> given problem
so
That means ----> ∅ Is in the fourth quadrant
step 1
Find the value of [tex]sin(\theta)[/tex]
we have
[tex]csc(\theta)=-\frac{12}{5}[/tex]
we know that
[tex]csc(\theta)=\frac{1}{sin(\theta)}[/tex]
therefore
[tex]sin(\theta)=-\frac{5}{12}[/tex]
step 2
Find the value of [tex]cos(\theta)[/tex]
we know that
[tex]sin^2(\theta)+cos^2(\theta)=1[/tex]
we have
[tex]sin(\theta)=-\frac{5}{12}[/tex]
substitute
[tex](-\frac{5}{12})^2+cos^2(\theta)=1[/tex]
[tex]\frac{25}{144}+cos^2(\theta)=1[/tex]
[tex]cos^2(\theta)=1-\frac{25}{144}[/tex]
[tex]cos^2(\theta)=\frac{119}{144}[/tex]
[tex]cos(\theta)=\frac{\sqrt{119}}{12}[/tex] ---> is positive (IV Quadrant)
step 3
Find the value of [tex]tan(\theta)[/tex]
we know that
[tex]tan(\theta)=\frac{sin(\theta)}{cos(\theta)}[/tex]
substitute the values
[tex]tan(\theta)=-\frac{5}{12} : \frac{\sqrt{119}}{12}=-\frac{5}{\sqrt{119}}[/tex]

The slope is Five-halves, and the y-intercept is 4.
The slope is 4, and the y-intercept is Negative five-halves.
The slope is 4, and the y-intercept is Five-halves.
Answer:
The slope is 4, and the y-intercept is Negative five-halves
Step-by-step explanation:
we have
[tex]8x-2y=5[/tex]
This is the equation of the line in standard form
Convert the equation in slope intercept form
[tex]y=mx+b[/tex]
where
m is the slope
b is the y-intercept
Isolate the variable y
Subtract 8x both sides
[tex]-2y=-8x+5[/tex]
Divide by -2 both sides
[tex]y=4x-\frac{5}{2}[/tex]
therefore
[tex]m=4\\b=-\frac{5}{2}[/tex]
The slope is 4, and the y-intercept is Negative five-halves
Given that,
The linear function that is represented by the equation 8 x minus 2 y = 5.Based on the above information, the calculation is as follows:
8x - 2y = 5
We know that y = mx + b
Here
m is the slope
b is the y-intercept
Isolate the variable y
So,
-2y = -8x + 5
Now divide 2 by both sides

Line a is parallel to line b. Which statement about lines a and b is true?
The sum of the slopes of line a and line bis 0.
The product of the slopes of line a and line bis 1.
The product of the slopes of line a and line bis -1.
Line a and line b have the same slope.
Final answer:
Line a and line b, being parallel, have the same slope which is the defining feature of parallel lines.
Explanation:
When two lines, line a and line b, are parallel, they will never intersect and will have the same slope. Therefore, if line a is parallel to line b, the statement 'Line a and line b have the same slope' is true.
In the context of the slope of lines, the sum of the slopes of line a and line b would not be 0 unless both slopes are zero, which is typically not the case for non-horizontal lines. The product of the slopes would not be 1 or -1 either, unless one of the lines is perpendicular to the other, which would imply that the lines are not parallel. Therefore, the characteristic feature of parallel lines is that their slopes are identical.

Weekly wages at a certain factory are
normally distributed with a mean of
$400 and a standard deviation of $50.
Find the probability that a worker
selected at random makes between
$300 and $350.
Answer: 0.1359
Step-by-step explanation:
mean = $400
Standard deviation = $50
Since the wages is normally distributed , the first thing is to find the z - score.
z = [tex]\frac{x-mean}{standard deviation}[/tex]
finding the z - value for 300 and 350 , we have
z = [tex]\frac{300-400}{50}[/tex]
z = [tex]\frac{-100}{50}[/tex]
2 = -2
also
z = [tex]\frac{350-400}{50}[/tex]
z = [tex]\frac{-50}{50}[/tex]
z = -1
The next thing is to check the calculated value on z - table.
From z - table :
P (z[tex]\leq[/tex] -2 ) = 0.0228
P ( z [tex]\leq -1[/tex] ) = 0.1587
combining the two
P ( -2[tex]\leq[/tex]z[tex]\leq[/tex]-1 ) = 0.1587 - 0.0228
P ( -2[tex]\leq[/tex]z[tex]\leq[/tex]-1 ) = 0.1359
