Answer:
<u>390.4 in.²</u>
Step-by-step explanation:
- Area of sector = πr² x θ/360
- Area = 22/7 x 64 x 70/360
- Area = 11 x 10 x 32 x 1/9
- Area = 320 x 11/9
- Area = 320 x 1.22
- Area = <u>390.4 in.²</u>
<h2>Step-by-step explanation :</h2>
Total shared part:
1/4 + 1/8
Taking LCM and adding:
2/8+1/8
Adding gives:
3/8
Well, if you are asking how to do it, than you would probably first make a book, then on each page write a different math statagy, such as using the factor tree.
A number with exactly 14 divisors can be of one of the two following forms...
<span>p^6 * q </span>
<span>OR </span>
<span>p^13 </span>
<span>where p and q are prime. </span>
<span>From here it should be obvious that the smallest such number is 2^6 * 3 = 192</span>
We have a geometric sequence----------- > <span>{-4, 12, -36, ...}
</span><span>
the formula is a(r)^(n-1)
a------------- >a is the first term------------ > -4
r--------------- > </span><span>is the common ratio------- > 12/(-4)=(-36/12)=-3
n--------------- > is the number of terms
</span>The fifth term is -4[(-3)^(5-1)]=-4[(81]=-324
the answer is -324
