Each successive term is 3 times the previous one, so you could write the sum as

$\displaystyle\sum_{i=1}^{10}4\times3^{i-1}=118096$

Solve equation for the given variable

Alenkinab [10]

Answer:

p=30

Step-by-step explanation:

First, you need to subtract 10 from both sides to get 1/2p=25. You do this just because simplifying is much easier.

Then, you need to isolate p, so you divide 1/2 by both sides, which is the same thing as multiplying by 2. 1/2*2p=15*2.

Simplifying, you get p=30.

You are choosing a new cell phone. The screen on your current phone is 10.8 cm high and 6.1 cm wide. The screen on the new phone

Leto [7]

Answer:

19.68 cm^2

Step-by-step explanation:

Area of Current Phone

First, find the area of the current phone. We can assume the screen is rectangular. The area of a rectangle can be found using:

a=l*w

We know the length is 10.8, and the width is 6.1, so we can substitute them in

a=10.8*6.1

a=65.88

Current Phone: 65.88 cm^2

Area of New Phone

Find the area of the new phone.

a=l*w

We know the length is 12.4, and the width is 6.9, so we can substitute them in

a=12.4*6.9

a=85.56

New Phone: 85.56 cm^2

Difference

We want to find how much larger the new phone screen is. To do this, find the difference between the new phone area, and the current phone area.

new phone - current phone

85.56-65.88

19.68

The new phone screen is 19.68 cm^2 larger than the current phone screen

What ratio is represented in the table ?

dezoksy [38]

1. The tables represent a ratio of 3:5. For example, 6 x 3 = 18, and 6 x 5 = 30. Also, 20 x 3 = 60, and 20 x 5 = 100.
2. The table has a ratio of 3:4, so the missing blank is 64.
