Answer:

Step-by-step explanation:

y = 450 × 1.18^t

:::::

450 × 1.18^t = 1,030

1.18^t = 1,030/450 = 103/45

t×ln(1.18) = ln(103/45)

t ≈ 5 hours

For each fraction below find an equivalent fraction with a denominator 200. <br><br>fraction 14/25​
Shtirlitz [24]

Answer:

112/200

Step-by-step explanation:

To find an equivalent fraction with a new denominator you can simply multiply by 1. However, you must multiply by different forms of 1. Remember that any number divided by itself is equal to 1. Additionally, because of the identity property of multiplication, any number multiplied by 1 is still equivalent.

In this case, you should multiply by a fraction that will make 25=200. To get 200 from 25 you must multiply by 8. So, multiply the whole fraction by 8/8. This gives you (14/25)*(8/8)=112/200.

1,459.75 - 200.25 - 359.45 - 125.00 - 299.35 = 475.70

475.70 + 375.00 = 850.70

Her account balance after the bills and deposit is $850.70
