Younger people don't own landline telephones so you are limiting your voter demographic to older people by calling them more than younger people.

The amount of interest earned from a savings account was $580. What was the interest rate if $1432 was deposited 6 years before
SSSSS [86.1K]

Answer:


Step-by-step explanation:

Solving our equation

r = 580 / ( 1432 × 6 ) = 0.06750466

r = 0.06750466

converting r decimal to a percentage

R = 0.06750466 * 100 = 6.7505%/year

The interest rate required to

accumulate simple interest of $ 580.00

from a principal of $ 1,432.00

over 6 years is 6.7505% per year.

What is greater than 3.2 x 10-3
Volgvan

Answer:

3.2x10-3=2.18 or x=2.18 So one thats greater is 8.0x+6-2=4.0 or x=4

Step-by-step explanation:

I wasnt sure about what they were asking but here.

3.2x=10-3                      8.0x+6-2

+3         +3                      +2     +2

3.2x+3=10                      8.0x+2=6

-3         -3                        -2       -2

3.2x=7                                8.0x=4

7/3.2 = 2.18                         ÷4     ÷4  

                                                 x=4

I think I did this a bit wrong...but I hope this helps a little bit!
