Answer:

(A) 261  

Step-by-step explanation:

We have to find the sum of summation of 3i+2 from i equals 5 to 13, that is

\sum_{i=5}^{13}(3i+2)

=3(5)+2+3(6)+2+3(7)+2+3(8)+2+3(9)+2+3(10)+2+3(11)+2+3(12)+2+3(13)+2

=17+20+23+26+29+32+35+38+41

=261

Thus, the sum of summation of 3i+2 from i equals 5 to 13 is 261.

I thought of a number, I added 1 3 4 to it, then I multiplied the result by 2 2 11 and I got 8. What was my number?
Valentin [98]

Given:

In a number, adding 1\dfrac{3}{4}, then multiplying the result by 2\dfrac{2}{11} we get 8.

To find:

The unknown number.

Solution:

Let the unknown number be x.

According to the question,

(x+1\dfrac{3}{4})\times 2\dfrac{2}{11}=8

(x+\dfrac{1\times 4+3}{4})\times \dfrac{2\times 11+2}{11}=8

(x+\dfrac{4+3}{4})\times \dfrac{22+2}{11}=8

(x+\dfrac{7}{4})\times \dfrac{24}{11}=8

Multiply both sides by \dfrac{11}{24}.

x+\dfrac{7}{4}=8\times \dfrac{11}{24}

x+\dfrac{7}{4}=\dfrac{11}{3}

Subtract \dfrac{7}{4} from both sides.

x=\dfrac{11}{3}-\dfrac{7}{4}

x=\dfrac{44-21}{12}

x=\dfrac{23}{12}

x=1\dfrac{11}{12}

Therefore, the required number is 1\dfrac{11}{12}.

A group of biologists found a total of 15 loggerhead turtle nests along a beach during a certain season. This was 20% of the tot
Andre45 [30]
20% also equals 1/5, right?

So in order to find the total number of turtle nests, just find 5/5, or multiply 15 by 5.

15 x 5 = 75

There were 75 total nests
