The table shows the type of super power that 36 students wish they had. Each student could only pick one super power.

tiny-mole [99]

The only statements that is true about the information on the table are:

The ratio of students who wish they had flight to those who wish for invisibility -Ratio 2:3. All other statements/ratios are false/incorrect.

<h3>How do we get the ratio of students who wish they had flight to those who wish for invisibility?</h3>

Ratio is simple math.

The number of people who wish for invisibility are: 12 ; while

The number of people who wish for flight are: 8

Thus the ratio will be given as:

8/12 further simplified by dividing by 4, we have

(8/4) : (12/4)

= 2:3

Hence, only the last statement is true.

What is 2/5 of a book to 1/2 of an hour as a unit rate?

hjlf

Answer: 4/5 book per hour

Step-by-step explanation: in this question, we are to rewrite (2/5)/(1/2) as unit rate.

To write this as a unit rate, what we need to do is to divide 2/5 by 1/2.

That means 2/5 divided by 1/2

Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour

Find an equation of the line that goes through the points (10,34) and (-1,10)

kotykmax [81]

Answer:

Given points are ( 10 ,34 ) and ( -1 , 10)

Step-by-step explanation:

The equation of line is given by 

first we can find slope (m) 

= (y2 - y1) / ( x2 - x1)

= 34-10/10+1

 =24/11

Now the equation is

y - y1 = m ( x - x1) 

y - 10 = 24/11 ( x +11)

11 ( y - 10 ) = 24 (x + 11)

11y - 110 = 24x + 264

24x + 264 +110-11y =0

24x - 11y + 374 = 0

which is the required equation

Solve the system of equations below using a matrix equation.

andreev551 [17]

Answer is b. ( -1, -5)

Answer is b. (-1, -5)

Step by step

Substitute the x and y values into both equations to find equality

Answer b. Makes both equations equal

2x + y = -7

2(-1) + (-5) = -7

-2 -5 = -7

-7 = -7
it equals now let’s do the 2nd one

x - y = 4

-1 -(-5) = 4

4 = 4

This one equals too. I did the math on the other three answers and they did not equal.
