Plss help I’ll mark brainliest
melamori03 [73]

Answer:

D 6

Step-by-step explanation:

Normally when I multiply mixed numbers, I change them to improper fractions first so that it is easier.

1\frac{2}{10} × 5 = \frac{12}{10} × 5

Multiply 5 by the numerator of the fraction and leave the denominator alone.

\frac{12}{10} × 5 = \frac{60}{10}

Change back to simplest form.

\frac{60}{10} = 6

Which set of numbers best describes the possible values of x in the equation below?[x-1]=[x] all integer values of x all real nu
SCORPION-xisa [38]

[x] represents floor function also called as Greatest integer function.

Floor function is the function that takes as input a real number and gives as output the greatest integer less than or equal to.

like [1.5]=1

[0.7]=0

[-0.3]=-1

Now we have to find set of x-values which satisfies equation [x-1]=[x]

Due to -1 in [x-1], it always produces output value one less than value of [x]

for example when x=0.5 then [x]=[0.5]=0, [x-1]=[0.5-1]=[-0.5]=-1

when x=1.5 then [x]=[1.5]=1, [x-1]=[1.5-1]=[0.5]=0

when x=3 then [x]=[3]=3, [x-1]=[3-1]=[2]=2

From above results we can see that there is no value of x which satisfies the given equation [x-1]=[x]

Hence there is NO solution.

In the diagram below what is the approximate length of the minor arc XY
sveta [45]

C = 2pi r= 2 (3.14) (27) = 169.56

Let XY = x

169.56 / 360 = x / 60

360x = 169.56 * 60

360x = 10173.60

x = 28.26

x = 28.3

Answer is C. 28.3 cm
