Answer:


Step-by-step explanation:

This question asks for the sum of the first 5 terms of the series.

Looking at the first 3 terms, we can see that each successive term is half of the one before it.

<em>So next term after 100 would be 50. Next term after 50 would be 25.</em>


Thus, we can write:

400 + 200 + 100 + 50 + 25 + ...

We already have first 5 terms, the sum is:

400 + 200 + 100 + 50 + 25 = 775

Answer choice B is right.

The correct answer is B) 775 

Why 775? Because Assume the series continues.

400+200+100+50+25=775

I hope this helps. 

Have a great day. :)

Ryan buys a bag of cookies that contains 8 chocolate chip cookies, 4 peanut butter cookies, 4 sugar
Pavlova-9 [17]

Answer:

4/69 to be exact. Slightly greater than 1/18

Step-by-step explanation:

The chance of selecting the PB cookie on the first try is 4 out of 24 or 1 out of 6. There are now 23 coolies left; 8 are chocolate, so 8/23 chance. (Slightly greater than 1/3) The chance of both events happening is the product if the individual events' chances. So multiply 1/6 times 8/23 to get 8/138. That reduces to 4/ 69. If he had put that first cookie back, the multiplication would have been 1/6×1/3. A lot easier.

Solve for b2: A=1/2h(b1+b2)
balandron [24]

Answer:

Step-by-step explanation:

A = \frac{1}{2}h(b_{1} + b_{2})

First let's multiply both sides by 2 to remove the \frac{1}{2} fraction:

2A = h(b_{1} + b_{2})

Next, let's divide both sides by h:

\frac{2A}{h} = b_{1} + b_{2}

Finally, let's subtract b_{1} from both sides:

b_{2} = \frac{2A}{h} - b_{1}
