5 0

Answer:

8 < x < 40

Step-by-step explanation:

x − 8 must be more than 0, but it can't be greater than 32.

0 < x − 8 < 32

8 < x < 40

A more precise answer would require law of cosines and calculus.

A number decreased by 7%
Mariulka [41]
X-7/100
OR
X-0.07
Since we don't know the number we need a variable which can be any alphabet so I chose "X".
For example if it were 7 decreased by 7 percent, it would be equal to:
7 - 7/100=6.93

Susan made 4 uniform annual deposits of $1800 in a savings account that earned an interest rate of 2% per year. Her last deposit
Norma-Jean [14]

Answer:

"$ 2,880" is the right answer.

Step-by-step explanation:

The given values are:

Annual deposit,

PV = $1,800

Interest rate,

r = 2%

or,

  = 0.02

As we know,

⇒  FV=PV\times (1+r)n

On substituting the values, we get

⇒         =1,800\times  (1 + 0.02) 4 + 7 + 13

⇒         =1,800\times (1.02)24

⇒         =1,800\times 1.6

⇒         = 2,880 ($)
