Convert 980 seconds to minutes... explain please ​

Mathematics
1 answer:
Murrr4er [49]2 years ago
3 0

The correct answer, in minutes, is:  " 16 \frac{1}{3} minutes ".
_____

[<u>Note</u>:  This is the same value as " 16 minutes and 20 seconds."].
_____

Step-by-step explanation:

Convert 980 sec to "minutes".

Note the exact conversion:
  60 sec = 1 minute.

 
So: Given the values in this question:
  60 sec / 1 minute = "x  minutes/ 980 sec" ;

that is:

 " \frac{980 sec}{1}  *\frac{1 min}{60 sec}  " ;
The units: "sec" ["seconds"] cancel out to: " 1 " ;

 since: " [sec / sec = 1 ] ;   and we can simplify and rewrite:

   " \frac{980 min}{60} = \frac{980}{60} min."

 →  Now, cancel out the last numerical value of "zero"
                  (in both the numerator and the denominator);  that is: to simplify the expression further—by dividing each side by "10" ;

              to get:  " \frac{98}{6} min."

Then: divide the numerator by the denominator:
        "[ 98 ÷ 6 = 16 \frac{1}{3} minutes ] ; — which is our answer.

<u>Note</u>: "1/3" of:  "1 minute"  = (1/3)*(60 seconds) = 20 seconds.

So;  "16 1/3" minutes = 16 minutes and 20 seconds".

_____
The correct answer, in minutes, is:  " 16
\frac{1}{3} minutes ".
  [<u>Note</u>:  This is the same value as " 16 minutes and 20 seconds."].

Graph each linear equation that passes through the given pair of points. Use graph paper.
Naya [18.7K]

Answer:

The easier way to solve this is to find the two points in the coordinate axis, and just draw a line that passes through the two points.

But let's be more complete:

Let's find the equations for each line:

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

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

1) Here the points are (2,2) and (4,5)

then the slope is:

a = (5 - 2)/(4 - 2) = 3/2

y = (3/2)*x + b

And to find the value of b, we just replace the values of one of the points in the equation, in this case i will use (2, 2)

2 = (3/2)*2 + b

2 = 3 + b

2 - 3 = b

-1 = b

y = (3/2)*x - 1

2) Here the points are (0,1/2) and (2,3/2)

then the slope is:

a = (3/2 - 1/2)/(2 - 0) = 1/2

y = (1/2)*x + b

And to find the value of b, we just replace the values of one of the points in the equation, in this case i will use (0, 1/2)

1/2 = (1/2)*0 + b

1/2 = b

y = (1/2)*x + 1/2

3) Here the points are (-1,2) and (5,0)

then the slope is:

a = (0 - 2)/(5 + 1) = -1/3

y = (-1/3)*x + b

And to find the value of b, we just replace the values of one of the points in the equation, in this case i will use (-1, 2)

2 = (-1/3)*-1 + b

2 = 1/3 + b

2 - 1/3 = b

5/3 = b

y = (-1/3)*x + 5/3

4) Here the points are (-5,-3) and (-3,5)

then the slope is:

a = (5 + 3)/(-3 + 5) = -4

y = -4*x + b

And to find the value of b, we just replace the values of one of the points in the equation, in this case i will use (-3, 5)

5 = -4*-3 + b

5 = 12 + b

5 - 12 = b

-7 = b

y = -4*x - 7

Now that we have all the equations, we can find the graphs.

where the colors are:

(4) green

(3) orange

(2) Blue

(1) Gray.

Can somebody please give me a step by step explanation. I have the answer I just don’t know how to show work!!!!!!! Please!!!
krek1111 [17]

Answer:

5391.76

Step-by-step explanation:

We have a rectangle and 2 semicircles

First find the area of the rectangle

A = l*w

A = 44*88= 3872

Then we know that 2 semicircles = 1 circle

The area of a circle is

A = pi r^2

The diameter is 44 so the radius is 22

A = pi * 22^2

A = pi484

A =1519.76

Add the areas together

1519.76+3872
