Answer:

5.75 days

Step-by-step explanation:

Write a proportion:

1440 Wh / 1 day = 8280 Wh / x

Cross multiply:

1440 x = 8280

Solve for x:

x = 5.75

It takes 5.75 days.

If 1,440 watts are used per day then you just divide.

8,280 / 1,440 = 5.75 or 5 days and 18 hours.

Hope This Helped! Good Luck!

Help me plz it’s sooo hard for me!
Len [333]
To find volume, multiply length x width x height.

4 1/2 x 5 x 3 1/4
4.5 x 5 x 3.25 = 73.125

1/4 = 0.25

Divide the total of the large cube to the small cube.

73.125/0.25 = 292.5

292 and 1/2 of the small cube(s) are needed to fill the right rectangular prism.

hope this helps

Answer:

Bank A

Step-by-step explanation:

We find the Simple Interest for each Bank

Bank A

A savings account at bank A earns 5%

simple interest.

Where

P = $5,000.00

R = 5%

T = 2 years

Compound quarterly = 4

First, convert R percent to r a decimal

r = R/100

r = 5%/100

r = 0.05 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 5,000.00(1 + 0.0125/4)(4)(2)

A = $ 5,522.43

A = P + I where

P (principal) = $ 5,000.00

I (interest) = $ 522.43

For Bank B

P = $5,000.00

R = 4%

T = 2 years

Compound quarterly = 4

First, convert R percent to r a decimal

r = R/100

r = 4%/100

r = 0.04 per year,

Then, solve our equation for A

A = P(1 + r/n)nt

A = 5,000.00(1 + 0.01/4)(4)(2)

A = $ 5,414.28

A = $ 5,414.28

A = P + I where

P (principal) = $ 5,000.00

I (interest) = $ 414.28

Therefore, the bank that would give Gabriel more interest is Bank A
