Answer:
Yes
Step-by-step explanation:
In mathematics, a rational number is a number such as -3/7 that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Every integer is a rational number: for example, 5 = 5/1.
An Irrational ia (of a number, quantity, or expression) not expressible as a ratio of two integers, and having an infinite and nonrecurring expansion when expressed as a decimal. Examples of irrational numbers are the number π and the square root of 2.
Rational numbers include natural numbers, whole numbers, and integers. They can all be written as fractions. Sixteen is natural, whole, and an integer. Since it can also be written as the ratio 16:1 or the fraction 16/1, it is also a rational number.
In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers.
So, it is rational
Answer:
<u>Part 1:</u> Angle = 154.3°
<u>Part 2:</u> About 2.33 Rotations
Step-by-step explanation:
Part 1:
The arc length of a circle is given by the formula 
Where
- s is the arc length
- r is the radius of the circle
is the angle
**The angle are in radians and we will use radian**
When smaller gear has made 1 complete rotations (
radians), the arc length traveled is 
Now, what angle is swept by the larger circle when it travels 
? Put in 
and r is 7 to find :
** Since 
radians is 180°, we plug in 180 into and find the degree measure:
Angle = 154.3°
Part 2:
In one complete rotation of the larger gear, it travels a distance of:
We know that the smaller circle makes 1 rotation and travels 
, so in 
distance, it makes:
Rotations = 
About 2.33 Rotations
Answer: first blank is 4/25.
second blank on the top row is 16:100=4:25.
First blank on the second row is 13/50.
The second blank on the second row is 26:100=13:50.
The first blank on the third row is 33:50.
The first blank on the fourth row is 4/7.
The second blank on the fourth row is 57%.
The third blank is 0.57.
Step-by-step explanation:
16/100 simplified is 4/25. 16÷4=4 100÷4=25
ratios are also fractions.
26/100 simplified is 13/50. 26÷2=13 100÷2=50
66/100 simplfied is 33/50. 66÷2=33 100÷2=50
4÷7(rounded down)=0.57
