How should I solve this to get the elapsed time

Mathematics

Answer:

Subtract the hours to get 12-3 = 9

Or you could start at 3 PM, and count your way up one hour at a time, until you get to 12 AM. You should count out 9 hours in total.

An alternative is you could note from 3 PM to 3 AM is a span of 12 hours. Take 3 hours away from 3 AM, and you'll rewind the clock back to 12 AM. So 12-3 = 9. :-)

plz brainlist plz ;-)

Perfect pizza has 16 toppings listed on their menu. how many ways could a customer choose a pizza that contains 5 different topp
marishachu [46]

Answer:

4368 ways

Step-by-step explanation:

Use nCk for this. 16C5. This is \frac{n!}{(n-k)!(k!)}. This becomes\frac{16!}{(11!)(5!)}. This is \frac{16*15*14*13*12}{5*4*3*2*1} due to 16! and 5! canceling out. This becomes 4368.

Quadriatic formula 2w^2-28w=-98
alina1380 [7]
To apply the quadratic formula, the right side must be equal to 0.

2w^2-28w=-98 \\ 2w^2-28w+98=0

Now you can apply the quadratic formula \frac{-b\±\sqrt{b^2-4ac}}{2a} to find the solution for w.

\frac{-(-28)\±\sqrt{(-28)^2-4(2)(98)}}{2(2)} = \frac{28\±\sqrt{784-784}}{4} = \frac{28}4 = \boxed{7}

(The quadratic formula is highly unnecessary in this problem, however. You could easily divide all values by 2 to get w²-14w+49=0, which factors into (w-7)²=0, for which 7 is the only solution which puts a factor of the quadratic equal to 0.)

Determine the value of e.
Softa [21]

9514 1404 393

Answer:

  A)  16

Step-by-step explanation:

The ratio of long-side to short-side is the same for all of these similar triangles, so we have ...

  e/8 = 8/4

  e = 8(8/4) = 8(2) = 16

The value of e is 16.

Classify the object with the given side lengths as acute, obtuse, right, or not a triangle.
iren [92.7K]

Answer:

We have to first see that the given lengths makes a triangle or not by using a+b > c in which a,b and c are

length of sides of a triangle lets check out

16 + 21 = 37 > 28

21 + 28 = 49 > 16

16+ 28 = 44 > 21

As because the statement fits correct in the lengths given so its a triangle

So we can say that the triangle is scalene by means of measurements

but cant be a right angle as by taking the pythagorean triplet

= a^2 + b ^ 2 = c^2

lets see if a=16, b = 21 and c = 28

So a^2 + b^2

= 256 + 441

= 697

but c^2

= 28^2 = 784

As 441 =/= 784

So The triangle lengths cant be a right angled triangle

So 1/2 of possibility is the traingle acute and 1/2 of the possibilty that the triangle is obtuse

Now you can find the correct triangle on the basis of acute or obtuse angle by drawing with given length of sides of triangle

Hope it helps
