Answer:

6. (a) 7. (b) Im pretty sure 8. (d)

Step-by-step explanation:

A real number is basically any number whatsoever, meaning a real number can also be irratonal.

Paul is three times as old as Mary and Peter is four times as old as Mary,If the sum of their ages is 64, how old are Peter,Paul

uysha [10]

Let Mary's age be x.

Paul is three times as old as Mary, so Paul's age would be 3x.

Peter is four times as old as Mary, so Peter's age would be 4x.

The sum of their ages is 64
⇒ Paul's age+ Peter's age+ Mary's age= 64
⇒ 3x+ 4x+ x= 64
⇒ 8x= 64
⇒ x= 64/8
⇒ x= 8

Paul's age is: 3x= 3*8= 24

Peter's age is: 4x= 4*8= 32

Final answer: Paul is 24 years old.
Peter is 32 years old.
Mary is 8 years old.

Hope this helps~

x + 2.4 + 3.5 = 176.6
x + 5.9 = 176.6
x = 176.6 - 5.9

An experienced cashier at a grocery store takes 2 seconds to scan each item and 40 seconds to process the customer's payment. 1)

grigory [225]

Answer:

The correct option is D) 43 items.

Step-by-step explanation:

As we know that total given time is ,

$Y = (60\times2) +6 =126\hspace{0.15cm} sec$ ,

Out of which cashier spends 40 seconds to process the customer's payment.

So the remaining time = (126 - 40) = 86 secs.

And the remaining time is used to scan the item and so that we can calculate here the no items scan is = (86 ÷ 2) = 43.

Therefore we can say that 43 items are being purchased.
