How many calls will you need to make to hit your sales target for the month I need to make 23 more sales. My current close ratio is 1:3.5, so I will need to make?

Closing ratio is the number of deals you close compared to the number of presentations ( or calls ) you make. In this case it means: 1 sale : 3.5 calls ( average ). We will use proportions: 1 : 3.5 = 23 : x. x = 23 * 3.5, x = 80.5. We have to round this number upwards to be more certain that you get the 23 sales. Answer: 81 calls

Hey tiger has a mass of 34 KG and runs with a speed of 8.5 m/s what is the Connecticut Energy of the tiger?

(this is if you are asking about kinetic energy which I believe you are asking about)

In order to solve this, you need to first use the formula for kinetic energy which is K=1/2mv² (K being Kinetic energy, M being mass, and V being velocity)
Now plug the numbers into the equation, so you get K=1/2(34)(8.5 ²)

After multiplying everything, you would get 1228.25 joules

Nicholas spends 20 minutes iron shirts with his 1800 watt iron how many joules of energy were used by the iron


1 watt = 1 joule/sec

(1800 joule/sec) x (20 minutes) x (60 sec/minute) = 2,160,000 joules
             
                                                                                (2.16 megajoules)

I wouldn't exactly say that this energy was "used" by the iron.
What the iron did was to take 2.16 megajoules of electrical energy
and convert it into 2.16 megajoules of heat . . . something that the
things we build are very good at, and which we know how to do with
nearly 100% efficiency.

QUESTION POSTED AT 08/12/2019 - 08:03 AM

Im not sure how to figure this circuit out


Yes, this is certainly ugly and scary.
Here's how to go about it:

-- Take the two resistors in the middle ... the  9  and the  8 .
   They're in parallel.
   Their equivalent resistance is something like 4.24 ohms.  Whatever.

-- Take the two resistors around the outside on the right ... the 4 and the 6 .
    Together, in series, they're equivalent to  10 ohms.

-- That 10 ohms is in parallel with the ~4.24 ohms in the box.
    Now you have something like  2.98 ohms, all to the right of the 3 on top.

--  That 2.98 is in series with the 3.0 on top.
     So there's  5.98 ohms.

-- The 20.0 is in parallel with the  5.98 ohms.
    So that's about 4.6 ohms equivalent between 'A' and 'B'.

That's just off the top of my head.  I won't sharpen it down
any further than that, because it's only 5 points, and you
should be able to do it now, using this approach.

How is the scientific meaning of acceleration different from how we use the term acceleration in everyday life?


Most people think that "acceleration" means "speeding up". 
(Maybe you use the word that way.  I don't.)
I think this comes from the gas pedal in the car being called
the "accelerator".

The real meaning of "acceleration" is: any change in motion ...
speeding up, slowing down, or changing direction even if speed
doesn't change.
