Answer:

36 minutes past 1, or 1:36

Step-by-step explanation:

A watch normally has an hour hand that does one revolution in 12 hours.

It takes 1 hour to go from the 1 o'clock position to the 2 o'clock position.

Since 1 hour equals 60 minutes, it takes 60 minutes to go from the 1 o'clock position to the 2 o'clock position.

The hour hand is 3/5 of the way from 1 to 2, so the number of minutes past 1 o'clock is 3/5 of 60 minutes.

3/5 of 60 minutes =

= 3/5 * 60 minutes

= 3/5 * 60/1 minutes

= 180/5 minutes

= 36 minutes

The time is 36 minutes past 1, or 1:36

List at least two technology tools that can help with calculating future value of an investment. Using complete sentences, expla
Setler79 [48]

Answer:

  • scientific or graphing calculator
  • TVM solver
  • spreadsheet

Step-by-step explanation:

For many future-value calculations, a scientific calculator is a sufficient tool. Of course, one must know the appropriate formula to use.

A good alternative when the calculation is a little messy is a TVM solver or special-purpose financial calculator. I prefer this tool because it requires little more than entering numbers in to the right slots.

Most modern spreadsheet programs and apps come with financial formulas built in. So, they, too, can be easy tools to use for calculating future value. These are especially handy when a number of scenarios need to be explored. (I always have to look up the formulas to see which one is appropriate and what its inputs are. So, I find a spreadsheet less useful for a simple calculation.)

The absulote value of -8 and 5
Blababa [14]

The absolute value of -8 is 8 and the absolute value of 5 is 5. Absolute value is basically the number's distance from 0 on a number line, basically how many numbers it is away from 0. For that reason, it's always positive, regardless of whether or not the number is positive or negative. Hope this helped!

X=cost per hamburgurs
y=cost per hot dog

200x+150y=1450
200x+250y=1750

we can multiply first equation by -1 and add to 2nd

-200x-150y=-1450
<u>200x+250y=1750 +</u>
0x+100y=300

100y=300
divide both sides by 100
y=3

sub back

200x+150y=1450
200x+150(3)=1450
200x+450=1450
minus 450 both sides
200x=1000
divide both sides by 200
x=5


the cost of a hamburgur is $5
the cost of a hot dog is $3

Find the missing side of the right triangle
o-na [289]

Answer:

<h2>1</h2>

Step-by-step explanation:

Use the Pythagorean theorem:

leg^2+leg^2=hypotenuse^2

We have

leg=3,\ leg=x,\ hypotenuse=\sqrt{10}

Substitute:

3^2+x^2=(\sqrt{10})^2

9+x^2=10             <em>subtract 9 from both sides</em>

9-9+x^2=10-9

x^2=1\to x=\sqrt1\\\\x=1
