If you are just factoring, just factor out a common term which is x. So you would have x(2x-9)

Is .21 (with only the one repeating) a rational number? please explain why! thanks!

Nostrana [21]

21 is a rational number because it is an integer, which can be converted into a fraction.

Step-by-step explanation:

When a denominater and numerator are integers and gives a quotient then it is a rational number.

21/1, where 21 is denominator and 1 is numerator the quotient is 21. Therefore 21 is a rational number which can also be considered as a ratio.

bogdanovich [222]

we are given

basketball player Chauncey Billups of the Detroit Pistons makes free throw shots 88% of the time

so, probability of making shot is

=88%

so, p=0.88

To find the probability of missing first shot and making the second shot

so, we can use formula

probability = p(1-p)

now, we can plug values

we get

$probability=0.88(1-0.88)$

So, the probability that he misses his first shot and makes the second is 0.1056........Answer

Answer as an improper fraction: 7/4

Answer as a mixed number: 1 & 3/4

Answer in decimal form: 1.75

Each answer above is a different way to represent the same distance

=========================================

Explanation:

I'm assuming the total distance is 5&1/4. This converts to the improper fraction 21/4 through the use of the formula below

a & b/c = (a*c+b)/c

In this case, a = 5, b = 1 ,c = 4

If each leg of the race is x miles, then the three legs add to x+x+x = 3x miles total. Set this equal to 21/4 and solve for x

--------------------------

3x = 21/4

(1/3)*3x = (1/3)*(21/4)

x = (1*21)/(3*4)

x = (21/3)*(1/4)

x = 7*(1/4)

x = 7/4

-------------------------

Each leg is 7/4 miles. Lets convert this to a mixed number through long division.

7/4 = 1 remainder 3

The two results above indicate that 7/4 = 1 & 3/4

To help confirm this, imagine you had 7 slices of pie and 4 people to divide those 7 slices among. Each person will get 1 slice meaning there are 7-4 = 3 slices leftover, aka the remainder.

If you need the answer in decimal form, then 1 & 3/4 = 1 + 3/4 = 1+0.75 = 1.75
