Answer:

  • 2084, 1.1111

Step-by-step explanation:

Q1

<u>Given GP</u>

  • 4, -20, 100,...

<u>Common ratio is: </u>

  • r = -20/4 = 100/-20 = -5

<u>Sum of 5 terms:</u>

  • S₅ = 4( (-5)⁵ - 1)/(-5 - 1) = 2084

Q2

<u>Given GP</u>

  • 1, 1/10, 1/100, ...

<u>Common ratio is:</u>

  • r = 1/10 : 1  = 1/100 : 1/10 = 1/10

<u>Sum of 5 terms:</u>

  • S₅ = 1*((1/10)⁵ - 1)/((1/10 - 1) = 1.1111

Keira , larry and gita picked apples at an orchard. keira picked twice as many pounds as larry and 3 times as many as gita. the
Natalija [7]
Number of apples in pounds picked up by Keira = K
Number of apples in pounds picked up by Larry = L
Number of apples in pounds picked up by Gita = G
Total number of apples they picked all together in pounds = 8360
Now from the given question, we know
Number of apples picked up by Kiera = 2L
So
K = 2L
L = K/2
Again Kiera picked up 3 times as many apples as Gita picked.
So,
K = 3G
G = K/3
Now if we add all the apples in pounds picked up by the three of them.
Then
K + L + G = 8360
K + (K/2) + K/3) = 8360
(6K + 3K + 2K)/6 = 8360
11K/6 = 8360
11K = 8360 * 6
11K = 50160
K = 4560
Then
L = K/2
   = 4560/2
   = 2280
G = K/3
   = 4560/3
   = 1520
Now we can say that
Kiera picked 4560 pounds of apple
Larry picked 2280 pounds of apple
Gita picked 1520 pounds of apple

Find the surface area of the cylinder use 3.14 for pi​
elena55 [62]

Answer:

351.658 square in

Step-by-step explanation:

First find the circumference of the circle

C = 25.13

Find area of the circle

A = 50.27

Multiply the circumference by the height

25.13 × 10 = 251.3

Add 251.3 with 50.27 twice

251.13 + 50.27 + 50.27 ≈ 351.658

Therefore your answer is D) 351.658 square in
