Answer:
23/99
Step-by-step explanation:
set up an equation
x = 0.232323...
100x = 23.2323...
use elimination
100x = 23.2323...
- (x = 0.232323...)
-------------------------
99x = 23
divide by 99
x = 23/99

a.Find the measure of the angle swept by the hour hand between noon and 9:55 pm
b. Find the exact angle between the minute and hour hands at 1:25 pm
Answers
Answer:
(a) The angle swept by the hour hand is 297⁰30′
(b) The exact angle between the minute and hour hand is 132⁰30′
Step-by-step explanation:
Given;
(a) angle swept by the hour hand between noon and 9:55 pm
between 12 pm and 9pm, there are 9 hours = 9 x 60 = 540 mins
9.55 pm = 540 mins + 55 mins = 595 mins
The hour hand moves 0.5 degree per minute
1 mins ---------------- 0.5 degrees
595 mins --------- ?
= 297⁰30′
(b) the exact angle between the minute and hour hands at 1:25 pm
for 25 mins, the hour hand had moved 12.5 degrees
Between 1 and 5, there are 20 mins moved by the minutes hand = 20 x 6°
= 120⁰
total angle = 12.5⁰ + 120⁰ = 132⁰30′

What is the probability that a randomly selected gas station in the United States charges less than per gallon (to 4 decimals)
Answers
This question is incomplete
Complete Question
The average price for a gallon of gasoline in the United States is $3.73 and in Russia it is $3.40 (Bloomberg Businessweek, March 5–March 11, 2012). Assume these averages are the population means in the two countries and that the probability distributions are normally distributed with a standard deviation of $.25 in the United States and a standard deviation of $.20 in Russia.
a. What is the probability that a randomly selected gas station in the United States charges less than $3.50 per gallon?(to 4 decimals)
Answer:
0.1788
Step-by-step explanation:
We solve this question using z score formula.
z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
a. What is the probability that a randomly selected gas station in the United States charges less than $3.50 per gallon?(to 4 decimals)
For the United States
x is the raw score = $3.50
μ is the population mean = Average price for a gallon of gasoline in the United States is $3.73
σ is the population standard deviation = standard deviation of $.25 in the United States = $0.25
z score = $3.50 - $3.73/$0.25
=-0.92
Determining the Probability value from Z-Table:
P(x ≤ 3.50) = P(x < 3.5) = P(z = -0.92)
= 0.17879
Approximately to 4 decimal places = 0.1788
Therefore, the probability that a randomly selected gas station in the United States charges less than $3.50 per gallon is 0.1788

Answers
Answer:
an infinite number
Step-by-step explanation:
The equation simplifies to ...
12x -7 = 6x +10 +6x -17 . . . eliminate parentheses
12x -7 = 12x -7 . . . . . . . . collect terms
0 = 0 . . . . subtract (12x-7) from both sides
This is true for all values of x. There are an infinite number of solutions.

Mis the midpoint of AB. If the length of the line segment AM is 20, and the length of the line segment MB is 3x +
8, what is the value of x?
Answers
Answer:
x = 4
Step-by-step explanation:
We know that M is the mid-point of AB. So,
AM = BM ( A mid point divides a line segment into 2 equal parts. )
Also it's given that length of AM is 20 & length of BM is 3x + 8.
But as AM = BM ,
[tex]20 = 3x + 8[/tex]
[tex] = > 3x = 20 - 8 = 12[/tex]
[tex] = > x = \frac{12}{3} = 4[/tex]

find the coordinates of the midpoint: (4,4) (4, -18)
Answers
Answer:
(4 , -7)
Step-by-step explanation:
Formula for finding the co-ordinate of the mid point through section formula :-
[tex](x',y') = (\frac{x^1+x^2}{2} , \frac{y^1+y^1}{2} )[/tex] where (x' , y') are the co-ordinates of the mid-point of the line segment whose co-ordinate points of ends of the line segment are (x¹ , y¹) & (x² , y²) .
In the question ,
x¹ = 4
y¹ = 4
x² = 4
y² = - 18
Using the values above in the formula ,
[tex](x',y') = ( \frac{4+4}{2} , \frac{4-18}{2} ) = (\frac{8}{2} , \frac{-14}{2}) = (4,-7)[/tex]

20 is what percent of 16?
Answers
Reading through the problem we have "20 is", that's
"20 equals", "what percent", "x/100", "of 16", times 16.
So we have the equation 20 = x/100 · 16.
So cross-canceling the 16 and 100 to 4 and 25, we have 20 = 4x/25.
Multiply both sides by 25 to get rid of the
fraction and we have 500 = 4x so 125 = x.
Remember the =question is asking for "what percent"
so we should write our answer as 125%.
Finally, check to see if the answer makes sense.
Does "20 is 125% of 16" make sense?
