The whole pizza comprises 360°
If each piece comprises 30° of the circle, there will be ;
360 / 30 = 12 pieces
I'm not quite sure I understand.
4 / 4 * 4 + 4 = 4
I'm not sure if that's what your asking four(no pun intended), but that's what I have to contribute.
Well you can do it by hand or use Google.
If you don't understand, I can explain, but if you don't want to work it by hand, then search it on google with x's replaced with *'s.
Well, it can't be expressed as an integer, but there are other ways.
This is one: \(\sqrt{75} = \sqrt{25*3} = \sqrt{25} * \sqrt{3} = 5 \sqrt{3}\)
You can also approximate: https://www.google.com/search?q=sqrt%2875%29
2) The bat costs $1.05, the ball costs 5 cents
First we do multiplication: (2 x 3) = 6
Now the power: 6^5 = 6 x 6 x 6 x 6 x 6 = 7,776
No need to post questions twice, the answerers will get to them when they can.
Is this valid?=(2 X 5)^32=10^32

Capcha keep asking me to verify, which makes entering multiple answers easy, btw.
(2/7) (9/7) = 18/ 49
i^50 =
[i^2]^24 * i^2 and i^2 = -1.....so we have....
(-1)^24 * -1 = [-1 to any positive even power = 1]
1 * -1 =
-1
01.2 times 10 to the second power minus 6 times 10 to the second power
1.2 x 10^2 - 6 x 10^2 =
120 - 600
-480
30 = 3 x 2 x 5
8 = 2 x 2 x 2
2 is the GCF
2*3^x=7*5^x rearrange as
(2/7) = (5^x / 3^x)
(2/7) = (5/3)^x take the log of both sides
log(2/7) = log(5/3)^x and we can write
log(2/7) = x log(5/3) divide both sides by log(5/3)
log(2 / 7) / log (5/3) = x ≈ -2.45
x^2 if x = -5 is 25.
3x if x = -5 is -15.
25 + -15 (or 25 - 15) = 10.
10-1=9.
Answer = 9
Please excuse the math novice here, but (and correct me if I'm wrong) it cannot be simplified further, unless you want to make decimals - in which case, it would be .40x + .50
{(0,1), (1,-3), (2,-4), (-4,1)}
Domain = {0, 1, 2, -4}
Range = {1, -3, -4, 1 }
It would be undefined.
Since these numbers have no factors in common, the Least Common Multiple = 22 x 7 = 154
the successive differences are
2 1/2, 5, 10
and you can see that these are doubling each time
\(\mbox{A recursive rule would be} \\ a[n] = a[n-1] + \left(\dfrac 5 2\right)\times 2^{n-1} ; a[0]=3\)
\(\mbox{An explicit rule would be} \\ a[n] = \dfrac {1+5 \times 2^n}{2}\)
2,2,3,5
Here's my best guess !!!!
(2 * 5)^(3^2) =
10^9 =
one billion
2x+40=(2/11)x multiply through by 11
22x + 440 = 2x subtract 22x from each side
440 = -20x divide both sides by -20
-22 = x
C(8,3)*(.45)^3*(.55)^5 = about 25.68%
quesion 1 is 6, bBCAUSE all # add up 15.
what are the common factors of 140 and 25?
25=5 X 5
140=2 X 2 X 5 X 7
As you can see, 5 is the only common factor of 25 and 140
