Express 1.21212121.... as a fraction
To solve such questions we will have to observe the fact that this is a repeating decimal number with the repeating figures being 2 and 1 as 21.
Thus, we can represent 1.21212121... as [tex] 1.\overline{21} [/tex]
Let us represent the original number 1.21212121... by the letter "a". Thus,
a=1.21212121...=[tex] 1.\overline{21} [/tex]
Therefore,[tex] a=1.\overline{21} [/tex]..................(equation 1)
Let us now multiply (equation 1) by 100 to get:
[tex] 100a=100\times 1.212121...=121.\overline{21} [/tex].....(equation 2)
Now, when we subtract (equation 2) from (equation 1), we will get:
[tex] 100a-a=121.\overline{21}-1.\overline{21} [/tex]
[tex] 99a=120 [/tex]
[tex] \therefore a=\frac{120}{99} [/tex]
Thus the given number 1.21212121... can be represented as a fraction as [tex] \frac{120}{9} [/tex].

What is the trigonometric ratio for sin z ?
enter your answer, as a simplified fraction, in the boxes.
$$
?
The trigonometric ratio for sin z is the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle.
The trigonometric ratio for sin z is defined as the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle. In other words, if we have a right triangle with angle z, sin z is equal to the length of the side opposite to angle z divided by the length of the hypotenuse.
Mathematically, sin z = opposite/hypotenuse.
For example, if we have a right triangle with angle z, and the length of the opposite side is 3 units and the length of the hypotenuse is 5 units, then sin z = 3/5.

From a cruising depth of 75 m below sea lever (BSL) the Nautilus descended to 105 m BSL and then rose to 80 m BSL. What is the total vertical distance the Nuatilus traveled?
Another Question -
A red kangaroo jumps along 40 km/h. At this rate how long would it take to jump 2 km in minutes?,
Final answer:
The Nautilus traveled a total vertical distance of 55 meters. A red kangaroo traveling at a speed of 40 km/h would take approximately 3 minutes to jump 2 km.
Explanation:
Total Vertical Distance Traveled by the Nautilus
To calculate the total vertical distance the Nautilus traveled, we need to add the distance it descended and the distance it ascended. The Nautilus descended from 75 m BSL to 105 m BSL, which is a distance of 105 m - 75 m = 30 m. Then it ascended from 105 m BSL to 80 m BSL, a distance of 105 m - 80 m = 25 m. So the total vertical distance traveled is 30 m + 25 m = 55 m.
Time for a Red Kangaroo to Jump 2 km
The speed of the kangaroo is 40 km/h. To find the time to jump 2 km, we first convert the speed to km/min: 40 km/h ÷ 60 min/h = 0.6667 km/min. Now, we divide the distance by the speed: 2 km ÷ 0.6667 km/min = 3 min. Thus, it will take the kangaroo approximately 3 minutes to jump 2 km.

The Truth About Antibacterial Soap
According to Discovery Fit & Health, about 75 percent of liquid soaps claim to be antibacterial. While this kind of soap sounds like a good idea, it is really not more effective than regular soap. Soap in general works by binding with dirt and grime and bacteria. This binding action allows the particles to be washed away easily. Antibacterial soap really does no more than regular soap. In fact, to be more effective than regular soap, antibacterial soap should stay on your skin for about two minutes to do what it claims it can do. Most people do not wash their hands that long. In addition, antibacterial soap may do harm. First it kills both beneficial and harmful bacteria. Second, scientists believe bacteria may become resistant to antibacterial agents over time, especially if they are not used correctly. Finally, antibacterial soap does nothing to viruses. Most of the time, we get sick from viruses, not bacteria. In sum, antibacterial soap does not live up to the hype. You are better off just using regular soap.

Find indicated values: m AB = m ABC = m BAC = m ACB =
Answer:
A. [tex]\text{m AB}=49^o[/tex].
B. [tex]\text{m ABC}=253^o[/tex].
C. [tex]\text{m BAC}=156^0[/tex].
D. [tex]\text{m ACB}=311^o[/tex]
Step-by-step explanation:
We have been given a circle and we are asked to find the arc measures of given circle.
Since we know that the measure of an arc that subtends to central angle equals the measure of central angle.
A. We can see from our circle that arc AB subtends to central angle AOB.
[tex]m\angle AOB=49^o[/tex]
[tex]\text{m AB}=49^o[/tex]
Therefore, measure of arc AB will be also 49 degrees.
B. First of all we will have to find the measure of arc BC.
Since we know that the sum of all central angles in a circle is 360°, so we can find the measure of arc BC by subtracting measure of arcs AB and AC from 360 degrees.
[tex]\text{m BC}=360^o-(\text{m AB+m AC})[/tex]
[tex]\text{m BC}=360^o-(49^o+107^o)[/tex]
[tex]\text{m BC}=360^o-156^o[/tex]
[tex]\text{m BC}=204^o[/tex]
We can see that ABC equals arc AB plus arc BC.
[tex]\text{m ABC}=\text{m AB}+\text{m BC}[/tex]
Upon substituting measures of arc AB and BC we will get,
[tex]\text{m ABC}=49^o+204^o[/tex]
[tex]\text{m ABC}=253^o[/tex]
Therefore, measure of arc ABC is 253 degrees.
C. We can see that arc BAC equals arc BA plus arc AC.
[tex]\text{m BAC}=\text{m BA}+\text{m AC}[/tex]
Upon substituting measure of arc BA and AC we will get,
[tex]\text{m BAC}=49^o+107^0[/tex]
[tex]\text{m BAC}=156^0[/tex]
Therefore, measure of arc BAC is 156 degrees.
D. We can see that arc ACB equals arc AC plus arc CB.
[tex]\text{m ACB}=\text{m AC}+\text{m CB}[/tex]
Upon substituting measure of arc AC and CB we will get,
[tex]\text{m ACB}=107^o+204^o[/tex]
[tex]\text{m ACB}=311^o[/tex]
Therefore, the measure of arc ACB is 311 degrees.

Why is circle 1 similar to circle 2?
A: Circle 1 and circle 2 have the same diameter.
B: Circle 1 is a dilation of circle 2 with a scale factor of 4.
C: Circle 1 is congruent to circle 2.
D: Circle 1 is a dilation of circle 2 with a scale factor of 0.25.
Answer:
Option B: Circle [tex]1[/tex] is a dilation of circle [tex]2[/tex] with a scale factor of [tex]4[/tex]
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal and is called the scale factor
All circles are similar and the scale factor is equal to the ratio of its radius or the ratio of its diameters or the ratio of its circumferences
Let
z------> the scale factor
A----> the radius of circle 1
B-----> the radius of circle 2
so
[tex]z=\frac{A}{B}[/tex]
we have
[tex]A=8x\ units[/tex]
[tex]B=2x\ units[/tex]
[tex]z=\frac{8x}{2x}=4[/tex]
The dilation is an enlargement because the scale factor is greater than [tex]1[/tex]

The table below shows the number of U.S. residents with health insurance in 2015, in thousands, categorized by age group and annual income. According to these results, if a U.S. resident with health insurance who was 35-64 in 2015 is selected at random, what is the approximate probability that this resident had an income between $50,000 and $79,999?
A. 0.20
B. 0.25
C. 0.40
D. 0.80
To determine the probability that a U.S. resident aged 35-64 with health insurance in 2015 had an income between $50,000 and $79,999.
Explanation:To calculate the probability that a randomly selected U.S. resident aged 35-64 with health insurance in 2015 had an income between $50,000 and $79,999, we would need specific data from the table mentioned in the question.
The process to find the probability would involve dividing the number of residents aged 35-64 with incomes between $50,000 and $79,999 by the total number of residents aged 35-64 with health insurance. The result would then be converted into a percentage to arrive at the probability.
Final answer:
To find the approximate probability of a U.S. resident with health insurance who was 35-64 in 2015 having an income between $50,000 and $79,999, we divide the number of residents in that category by the total number of residents with health insurance. The approximate probability is 0.1167.
Explanation:
To calculate the approximate probability that a U.S. resident with health insurance who was 35-64 had an income between $50,000 and $79,999 in 2015, we need to find the number of U.S. residents with health insurance in that age group and income category, and divide it by the total number of U.S. residents with health insurance.
From the given table, we can see that there were 32,500 U.S. residents with health insurance who were 35-64 years old and had an income between $50,000 and $79,999.
The total number of U.S. residents with health insurance in 2015, across all age groups, is 278,500.
So, the approximate probability is:
Probability = Number of U.S. residents with health insurance who were 35-64 and had an income between $50,000 and $79,999 / Total number of U.S. residents with health insurance
Approximate Probability = 32,500 / 278,500 = 0.1167
Therefore, the approximate probability that a U.S. resident with health insurance who was 35-64 in 2015 had an income between $50,000 and $79,999 is 0.1167.
