Answer:  $858.25

<u>Step-by-step explanation:</u>

The sum of a geometric sequence is: S_n=\dfrac{a_1(1-r^n)}{1-r}\ \text{where}\ a_1\ \text{is the first term and r is the ratio}

In the given problem, a_1=100 and r = 1.02

S_8=\dfrac{100(1-1.02^8)}{1-1.02}\\\\\\.\quad=\dfrac{100(1-1.17165)}{-0.02}\\\\\\.\quad=-5000(-0.17165)\\\\.\quad=858.25

stans cookie recipe makes 24 cookies and calls for exactly 384 sprinkles. he is wondering how many sprinkles (p) he will need to
Angelina_Jolie [31]

Answer:

960 sprinkles

Step-by-step explanation:

If 24 cookies call for EXACTLY 384 sprinkles, then 16 sprinkles fit on each cookie. 384/24 = 16

If 16 sprinkles fit on each cookie, 16 cookies on 60 cookies would be 960.

60 x 16 = 960

Answer:

SA = 1,176 ft².

Step-by-step explanation:

To find the surface area of the triangular prism, we can solve for the rectangular base, both triangular faces, and lateral sides separately.

For the rectangular base: (Use formula l×w)

20 × 18 = 360 ft²

For the triangular faces: (Use formula 1/2(b·h)

1/2(18 × 12) = 108 ft²

Since there are two faces, we need to double the amount.

108 × 2 = 216 ft².

Finally, solve for the lateral sides:

20 × 15 = 300 ft².

There are two sides, so:

300 × 2 = 600 ft².

Add up all of these areas:

600 + 216 + 360 = 1,176 ft²

Zinaida [17]
The way i do it, is sort of like this :

Is 7 a factor of 42? 
  Is 5 a factor of 42? 

7 is a factor of 42. 
It must be in multiples of 7!

Therefore, we have 5 on the other side, which makes it 5 x 7 = 35
