If it is moved to the tens place = xxx,x7x then it's value will decrease, it will become 70 only.

Every placement has its corresponding values, thus whereven the number 7 is place it is multiplied by its corresponding values (ones, tens, hundreds, etc).

dimaraw [331]

Answer:

Janies' monthly pocket money is $180.

Step-by-step explanation:

Janies' adjusted monthly pocket money:

Initial pocket money = $150

Ratio of new pocket money = 6:5

Let his new pocket money be represented by x,

x:$150 = 6:5

$150 x 6 = x (5)

$900 = 5x

x = $\frac{900}{5}$

x = $180

Therefore, Janies' monthly pocket money is $180.

Cindy is buying a new car and wants to learn how the value of her car will change over time. Insurance actuaries predict the fut

lawyer [7]

Answer:

$C=10000(0.852)^t$

Step-by-step explanation:

Let the exponential function be,

$C=a(b)^t$

Here, C = cost of the car

t = Duration or period in years

From the given table,

Two points representing cost of the car and time are (10000, 0) and (8520, 1),

For (10000, 0),

$10000=a(b)^0$

a = 10000

For (8520, 1)

8520 = $10000(b)^1$

$b=\frac{8520}{10000}$

b = 0.8520

Therefore, exponential equation will be,

$C=10000(0.852)^t$
