Roxanne set a goal o drinking 2.5 liters of water each day.By 10:00 a.M., she drank 3/4 liter, and at lunch she had another 600

dimaraw [331]

Answer:

She has to drink 0.05 liters more

Step-by-step explanation:

She has to drink 2.5 liters of water each day.

The total amount of water she drank is

3/4 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters

0.75 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters

2.45 liters + x liters = 2.5 liters

x liters = 2.5 liters - 2.45 liters

x liters = 0.05 liters

She has to drink 0.05 liters more or has not drunk 0.05 liters.

If she drinks 0.05 liters more she will reach her set goal.

3/4 liters

1 liter= 1000ml

3/4 liters= 3* 1000/4 ml

3/4 liters= 3000/4 ml

3/4 liters= 750 ml

750 ml/ 1000ml = 0.75 liters

Chaney deposits $1435.73 into a savings account that pays a simple annual interest rate of 1.32%. How much interest will she ear

kari74 [83]

Answer:

$57.61

Step-by-step explanation:

First you want to take the initial deposit and add the 1.32% by multiplying $1435.73 by 1.0132, which should look like this, 1435.73(1.0132), which makes it $1454.68. Next is the tricky part, now you add 1.32% of that new number, 1454.68(1.0132) which equals $1473.88. Then add 1.32% one more time, 1473.88(1.0132) which equals $1493.34. Lastly you subtract the initial deposit from the new number, 1493.34 - 1435.73 which equals $57.61 which is the amount of interest you would gain after 3 years!
