Sam needs to cut a piece of sheet metal into 8 pieces. It takes him 5 minutes to make each cut. How many cuts will Sam Make? Can you please explain i got 8 cuts as my answer

Answers

If we assume Sam would achieve his aim of cutting the metal into 8 pieces.

Then he will make 8 cuts. It takes him 5 minutes to make each cut. This is how long it takes to make the cut. This only tells us that he will take a total of 8*5 = 40 minutes, to make all the cuts.
 
Sam will make 8 cuts as stated in the question.

Hillgrove High School plays 3 soccer games. The team loses 2 of those games. According to the tree diagram, how many ways could this happen?

Answers

Answer:

Number of ways: 3

Step-by-step explanation:

Hill grove High School plays 3 soccer games.

The team loses 2 of those games.

Total number of games played = 3

Number of games loose, L = 2

Number of game won, W = 1

Possibilities:-

  • First game won and last two loose,  WLL
  • Second game won and first and last loose, LWL
  • last game won and first two loose, LLW

Please find attachment for tree diagram.

Hence, Total 3 ways this would happen.

You could do it 3 ways.
Hope this helps.

The four hand of a clock moves from 12 to 5 o'clock through how many degrees does it move?

Answers

to find the answer you have to first find how many degrees are there in between each number in the clock. the clock is 360°degrees and there are 12 numbers marked in a clock., so you have to divide 360 by 12 to get the number of degrees in between each number,
360°÷12=30° so there are 30°degrees between each number. 

if a clock hand moves from 12 to 5, it pass 5 numbers, so to get your final answer you have to multiply 30° by 5=150°.

so your answer is 150°degrees.
hope you can understand what i said. :)

The equation of line CD is (y − 3) = − 2 (x − 4). What is the slope of a line perpendicular to line CD?

Answers

The\ slope-point\ form:y-y_0=m(x-x_0)\ where\ m\ is\ a\ slope\n\nIf\ k:y=m_1x+b_1\ and\ l:y=m_2x+b_2\n\nk\perp l\iff m_1m_2=-1\to m_2=-(1)/(m_1)\n\ntherefore\nthe\ slope\ of\ line\ CD:y-3=-2(x-4)\ is\ m_1=-2\ and\ the\ slope\nof\ a\ line\ prpendicular\ to\ CD\ is\ m_2=-(1)/(-2)=(1)/(2)

Answer: 1/2
(y-3)=-2(x-4)
(y-3)= -2x+8
y= -2x+11
perpendicular slopes are always reciprocals and opposite so the slope would be
slope=1/2

WRITE EQUATION OF THE LINE PASSING THROUGH THE POINTS (5,4) AND (-6.3) Y=

Answers

First you have to find the slope of the line.  
(y2 -y1) / (x2 - x1) = slope
 so (3 - 4) / ( -6 - 5)  = -1/ -11 so the slope of the line is 1/11

Now you write y = mx + b  then substitute in one of the points with x and y
                     4 = (1/11)(5) + b
                     4 = 5/11 + b 
                 -5/11= - 5/11       change the 4 into 44/ 11 and subtract
     44 / 11 - 5/11=         b
                39/11 =     b                          now it depends on your teacher and text
usually, you can substitute the fraction for your b
     y = mx + b
     y = 1/11 x + 39/11   so this is your answer

Does that make sense or did I make a mathematical error?
( x - 5) / ( -6 - 5) = (y - 4)/( 3 - 4) <=>  (x-5)/(-11) = (y-4)/(-1) <=> x - 5 = 11y - 44 <=>
 x - 11y + 39 = 0;
