Answer:
1 and 1/2
Step-by-step explanation:
3 1/4 is equal to 13/4 and 1 3/4 is equal to 7/4. 13/4 - 7/4 is 6/4. 6/4 equalsn is 1 1/2.
Putting this as an arithmetic sequence gives:
The sum of the series = 16 x 7 x 7 = 784 m^3 = 784 000 L
The sum of an arithmetic series can be written as:
![S_n=n/2 [2a+(n-1)d] = 784 000 \\n/2[2(150)+(n-1)200] = 784 000 \\n[300+200(n-1)=1 568 000 \\300n+200n^2-200n = 1 568 000 \\200n^2+100n- 1 568 000 = 0 \\2n^2 +n- 15680 = 0 \\n= 88.2...,-88.7](https://tex.z-dn.net/?f=S_n%3Dn%2F2%20%5B2a%2B%28n-1%29d%5D%20%3D%20784%20000%0A%5C%5Cn%2F2%5B2%28150%29%2B%28n-1%29200%5D%20%3D%20784%20000%0A%5C%5Cn%5B300%2B200%28n-1%29%3D1%20568%20000%0A%5C%5C300n%2B200n%5E2-200n%20%3D%201%20568%20000%0A%5C%5C200n%5E2%2B100n-%201%20568%20000%20%3D%200%0A%5C%5C2n%5E2%20%2Bn-%2015680%20%3D%200%0A%0A%5C%5Cn%3D%2088.2...%2C-88.7)
n has to be positive, so we get
n =

Answer:
<u>144</u>
Step-by-step explanation:
Ok. I love problems like this.
You just have to find the surface are of each part and add it up!
To find the surface area of a rectangle, you multiple the base and the height. To find the surface area of a triangle, you multiple the base and height, and divide by 2 (because its half of a rectangle).
<u>Left rectangle:</u> 3*ll=33
<u>Middle rectangle:</u> 4*ll=44
<u>Right rectangle:</u> 5*ll=55
<u>Top triangle:</u> 3*4=12
12/2=6
<u>Bottom triangle:</u> 3*4=12
12/2=6
<u>ADD THEM ALL!!!</u> 33+44+55+6+6=<u>144</u>

You are trying to find the probability of a blue candy not containing nuts.
So since we're only looking at the blue, forget about every other row except that one.
So in total, there are 50 blue candies.
Without nuts, there are 20 blue candies.
20/50 = 0.4
Then move the decimal two points to the left to get your percentage.
The answer is:
B. 40%
