arsen [322]

Answer:

three quarter noted as as fraction would be 3/4

each quarter note is 1/4 of a whole note, or one beat in a measure of 4-4

so three of them would be

1/4+1/4+1/4=3/4

Rebecca has 12 photos she wants to hang side by side on her wall.A. If she only wants to display 8 of the photos, in how many wa

Mariana [72]

A.

If she will choose 8 from 12 photos, the total number of ways she can choose is given by a combination of 12 choose 8, since the order of the photos doesn't matter.

The formula for a combination of n choose p is:

$C(n,p)=\frac{n!}{p!(n-p)!}$

For n = 12 and p = 8, we have:

$C(12,8)=\frac{12!}{8!(12-8)!_{}}=\frac{12\cdot11\cdot10\cdot9\cdot8!}{8!\cdot4!}=\frac{12\cdot11\cdot10\cdot9}{4\cdot3\cdot2}=495$

So there are 495 ways.

B.

If she wants to arrange the 12 photos, the total number of ways is given by the factorial of 12:

$12!=12\cdot11\cdot10\cdot9\cdot8\cdot7\cdot6\cdot5\cdot4\cdot3\cdot2=479001600$

There are 479,001,600 ways.

C.

Since 10 photos already have specific places, we need to calculate the number of ways to arrange the other two photos in the two remaining places.

In this case, there are only 2 ways of organizing the remaining two photos:

Photo 1 first, photo 2 last, or photo 1 last and photo 2 first.

One number is the square of another. their sum is 182. find the numbers.

wariber [46]

$n-first\ number\\n^2-second\ number\\\\\text{The equation:}\\\\n+n^2=182\qquad\text{subtract 182 from both sides}\\\\n^2+n-182=0\\\\n^2+14n-13n-182=0\\\\n(n+14)-13(n+14)=0\\\\(n+14)(n-13)=0\iff n+14=0\ \vee\ n-13=0\\\\\boxed{n=-14\ or\ n=13}\\\\n^2=(-14)^2=196\ ot\ n^2=13^2=169\\\\Answer:\ \boxed{196\ and\ -14\ or\ 169\ and\ 13}$

Pyramide-shaped gift boxes have square bases that measure 5 inches on each side.The slant height is 6.5 inches.How much cardboar

andrew-mc [135]

1. square base area= 25 inches

2. using the slanted 6.5
=1/2base , therefore 5/2=2.5 inches

3. then use pythagoras.... c=6.5, a=2.5
c^2=a^2 + b^2
(do this urself)

4. when u find what b is... that's the height of one of the triangle
base= 2.5 (look at step 2 if u don't understand this bit)
height=b (refer to step 3)

5. then work out the area of 1 triangle using that...
6. then have (the answer u work out in step 5 ) multiply 4
this will give u the area for the all of the 4 triangles...

7. Then add together the square based area in step 1..(25)
to the 4 triangular, area faces (i.e from step 6) - the total will be ur answer for the amount of cardboard!!

p.s don't forget the units!!!
