A scale for a scale drawing is 10cm:1mm. which is larger the actual object or drawing explain

Answers

Answer 1

Answer: If I'm understanding your question, the drawing is 10cm and for every 10cm, the drawing is etched 1mm. This means that no matter how big the drawing gets, the actual object will always be bigger since it's 10cm larger always than the drawing. Hope this helped!

Answers

The number 2.3 is the coefficient, the number 10 is the base while the number 3 is the exponent.

In the scientific notation, a number is written followed b an exponent. It is necessary to note that the scientific notation is used to reduce the size of digits to something manageable.

The number 2,300 can best be represented as a number times 10 to some exponent in the manner 2.3 × 10^3. The number 2.3 is the coefficient, the number 10 is the base while the number 3 is the exponent.

In common scientific notation, any nonzero quantity can be expressed in two parts: acoefficient whose absolute value is greater than or equal to 1 but less than 10, and a power of 10 by which the coefficient is multiplied. In some writings, the coefficients are closer to zero by one order of magnitude. In this scheme, any nonzero quantity is expressed in two parts: a coefficient whose absolute value is greater than or equal to 0.1 but less than 1, and a power of 10 by which the coefficient is multiplied. The quantity zero is denoted as 0 unless precision is demanded, in which case the requisite number of significant digits are written out -- for example, 0.00000.

during the 2008 - 2009 season there were 801372 people who attended the home hockey games in Philadelphia there were 609907 people who attended the home hockey games in Phoenix how much greater was the home attendance in Philadelphia than in Phoenix that season?

Answers

there is a difference of 191'465 people.

you simply subtract 609907 from 801372 and you get 191465

The population P of a bacteria culture is modeled by P = 4100e^kt where t is the time inhours. If the population of the culture was 5800 after 40 hours, how long does it take for
the population to double? Round to the nearest tenth of an hour.

Answers

Enter the given values into the equation and solve.

5800 = 4100e^(k*40)

Divide both sides by 4100 and simplify:

58 / 41 = e^(k*40)

Remove e by taking the logarithm of both sides:

ln(58/41) = k *40

Divide both sides by 40:

k = ln(58/41)/40

k = 0.00867

Now for the population to double set up the equation:

2*4100 = 4100e^kt

The 4100 cancels out on both sides:

2 = e^kt

Take the logarithm of both sides:

ln(2) = k*t

Divide both sides by k

t = ln(2) /k

replace k with the value from above:

t = ln(2) / 0.00867

t = 79.95

Rounded to the nearest tenth = 80.0 hours to double.

Answer:

It would take around 122 hours to double the population.

Step-by-step explanation:

To answer the question, we first need to find the constant k, using the given information and the expression.

$P=4100e^(kt) \n5800=4100e^(k(40)) \n(5800)/(4100)=e^(40k)\ne^(40k)=1.41\nlne^(40k)=ln1.41\n40k=0.34\nk=(0.34)/(40)\approx 0.0085$

Now that we have the constant. We can find the time it would take to double the population which would be 11600:

$P=4100e^(kt)\n11600=4100e^(0.0085t)\n(11600)/(4100)= e^(0.0085t)\ne^(0.0085t)=2.83\nlne^(0.0085t)=ln2.83\n0.0085t=1.04\nt=(1.04)/(0.0085)\approx 122.35$

Therefore, it would take around 122 hours to double the population.

Each paper cup is a cone.
The volume if a cone is (1/3) (pi) (radius)² (height)

Notice, in the picture they labeled the diameter of the cup = 8 cm.
But we need the radius. that's 1/2 of the diameter = 4 cm.

So, the volume of these paper cups is

   (1/3) (pi) (4cm)² (11 cm) = about 184 cm³
=====================

It says that tons of lemons have been sacrificed, and you have
about 37,850 cm³ of lemonade.

How many cups will that fill ?

   37,850 cm³ / 184 cm³ = about 205 cups.
========================

How many packs of cups do you need to buy ?
Unfortunately, they only come in packs of 50.

1 pack = 50 cups . . . . . not enough
2 packs = 100 cups . . . not enough
3 packs = 150 cups . . . not enough
4 packs = 200 cups . . . oh so close but still not enough

You need to buy 5 packs = 250 cups.
=================================

It started raining, so you only sold 80% of the lemonade that you had.

80% means 0.80
"of" means "times"

You started out with 37,850 cm³ .

You sold (0.8) x (37,850 cm³) = about 30,280 cm³ of it.

How many cups did you fill with that much lemonade ?
(Remember, each cup holds about 184 cm³.)

   30,280 cm³ / 184 cm³ = about 164 cups sold.

You bought 250 cups to start out.
You sold 164 cups of lemonade.

You had (250 bought - 164 used) =

   86 clean, unused paper cups, still in the wrappers, left over.
