Answer:

(only ii right?)

Since we have the total number is 360° and our section is 72°, we know that the percentage of students who choose the cinema should be the number that we have divided to the total amount and then multiply the result by 100 ( it's fine if you write 100%, but when you actually calculate it, it's only 100, not 100%):

(72/360) . 100 = 20%

Evaluate the piecewise function at the indicated values from the domain:

lidiya [134]

In this question, we given a piece-wise function, that has different definitions depending on the domain.

Evaluate the function at x = 0.

The exercise asks for us to evaluate the function at $x = 0$

We have to look at the definition, and see which definition includes $x = 0$ . The equal sign at $x = 0$ is on the second definition, that is:

$f(x) = 1, 0 \leq x < 2$

Thus, at $x = 0$ , the value of the function is 1, and the correct answer is given by option A.

Find a rational number halfway in between the two numbers. 7/9 and 3/4<br><br>

AlekseyPX

Answer: 55/126

Step-by-step explanation:

For this equation, the easiest way to solve is to change the denominators, or bottom halves, of both fractions to be the same thing. The easiest way to do this is to multiply themselves with a “funny form” of one. A funny form of one is just a way of representing “1” with numbers that aren’t 1. “2/2” is a funny form of one. log(x)/log(x) is a funny form of one, etc..

(3/7)x(9/9)=27/63

(4/9)x(7/7)=28/63

These fractions are very close. If you are willing to settle for an unsimplified fraction, the answer here would be 27.5/63. If you aren’t willing to settle for the unsimplified form, we can multiply both fractions by a funny form of one again, most easily 2/2, and find the median of the two fractions.

(27/63)x(2/2)=54/126

(28/63)x(2/2)=56/126

The median of these two fractions is 55/126.

55/126 is exactly halfway between 3/7 and 4/9.

Yes help me please i need

The correct answer is C and E

Explain

A. 8x+4x=0

Now simply it

12x = 0

Now divide by 12 on both both side

X= 0

So this equation has the solution x= 0

B. 6x+2 = 4x+2+2x

Now both sides

6x+2=6x+2
Now simply by 6x+2 both sides

X= 0

So this equation has infinity solution

C. 4x-8x-3=6-4x

Now simply both sides

-4x-3=6-4x

Now simply

-3x=6

This equation have no solution

D. 5x+1 =1-5x

Now add 5x-1 on both sides

10=0
Now divide by 10

X= 0

This equation have solution x= 0

E. 12x-3-5x = 9+7x-6

Now simply both sides

7x-3= 7x+3

And subtract 7x from both sides

-3 = 3

So the equation has no solution

I hope this help you :D

Good luck
