3/12 irrational or rational number

2 answers:

4 0

Rational numbers are numbers that can be written as a fraction with both the numerator and denominators as whole numbers. Since 3 and 12 are whole numbers and they are in a fraction, $\frac{3}{12}$ is a rational number.

3/12=1/4 simplified and in decimal form it is .25 so it is RATIONAL because it ends. A rational number is any number that can be put into a form of a/B and B doesn't equal zero

Find the absolute maximum and minimum values of the function over the indicated interval, and indicate the x-values at which t

Yakvenalex [24]

Answer:

a. Maximum= 27, minimum= -5

b. Maximum= 19, minimum=-37

Step-by-step explanation:

We have the function $f(x)=8x-5$ . Since the function correspond to a line, then the maximum and minimum values of the function over an interval are in the endpoints of the interval.

Observe that if the line has negative slope then the minimum value is in the right endpoint. If the line has positive slope the minimum value is in the left endpoint of the interval.

The function f(x) has slope m=8. Then

a. the minimum value of f(x) in the interval [0,4] is reach when x=0, and the minimum is $f(0)=8*0-5=-5$ and the maximum is $f(4)=8(4)-5=32-5=27$

b. the minimum value of f(x) in the interval [-4,,3] is reach when x=-4, and the minimum is $f(-4)=8(-4)-5=-32-5=-37$ and the maximum is $f(3)=8(3)-5=24-5=19$

Choose all the fractions that are equivalent try to 4/20

vaieri [72.5K]

Answer: 1/2, 2/10, and 3/15

Explanation: Let's find 3 fractions that are equivalent to 4/20.

To find 3 fractions that are equivalent to 4/20,

notice that 4/20 is not in lowest terms.

In this situation, let's first rewrite 4/20 so that it's in lowest terms.

To do this, we divide the numerator and denominator by the

greatest common factor of 4 and 20, which is 4, and we have 1/5.

Since 1/5 is equivalent to 4/20, we can use

1/5 to find more equivalent fractions.

If we multiply 1/5 by 2 in both the numerator and

denominator, we get the equivalent fraction 2/10.

If we multiply 1/5 by 3 in both the numerator and

denominator, we get the equivalent fraction 3/15.

So 4/20 is equivalent to 1/5, 2/10, and 3/15.

Note that these are just 3 possible answers.

There are many other fractions that are also equivalent to 4/20.

Find the percent of increase from 290 to 490

d1i1m1o1n [39]

~169%
THIS IS NOT AN EXACT ANSWER

I took 490/290 and got 1.689655172, multiplied that by 290 and got 489.999 repeating, so I rounded up to 1.69 which translates to 169 percent.

I hope this helps :)
