Answer:

Step-by-step explanation:

Alright, so we know that they can unload 25 trucks in 5 hours.

If we do 25/5 We find out that they can unload 5 trucks per hour

Unfortunately, that is not one of the answers, so we will have to do some investigating to find something that is equivalent!

After evaluating the available answers, you can find that answer D lines up with our first assumption!

Every 1/5th of an hour the Fast-Pack people can unload a truck!

We can calculate this by writing:

1/5*25=5

Please let me know if you have any confusion! :)

Bank balance after 15 years is $950

Step-by-step explanation:

Step 1: Find the simple interest on the principal amount using the formula SI = PRT/100 where Principal (P) = $500, Rate of Interest (R) = 6% and Time(T) = 15 years

⇒ SI = 500 × 6 × 15/100 = $450

Step 2: Find total amount using the formula Amount = P + SI

⇒ Amount = 500 + 450 = $950

What has she done wrong?

Strike441 [17]

Answer:

see explanation

Step-by-step explanation:

Her error is in squaring (2y)²

She has (2y)² = 2y²

when it should be 2y × 2y = 4y²

Then

(2y)² = 6² + 8²

4y² = 36 + 64

4y² = 100 ( divide both sides by 4 )

y² = 25 ( take square root of both sides )

y = $\sqrt{25}$ = 5
