Answers

Answer 1
Answer:

According to the information given, using subtraction of time involving minutes, you should remind pj about her deliveries at 11:50 AM.

  • She will begin her deliveries at 12:20 PM.
  • You have to remind her 30 minutes before that.
  • 20 minutes before is 12 PM.
  • Before 12 PM, the times are AM.
  • 10 minutes extra have to be subtracted(20 already have), 60 subtracted by 10 is 50, hence:

You should remind pj about her deliveries at 11:50 AM.

7/15 multiplied by 5/14

Answers

so to solve this we multiply the numerator with the numerator and the denominator with the denominator 
 7       5
---- = ----
15     14
so thats 7×5 and 15×14 
the answer from the numerators →      35
                                                           -------
the answer from the denominators→  210

now find the GCF of the fraction which is 7 and divide both the top and bottom with it so 35÷7 and 210÷7 
answer from numerator →     5
                                              ---
answer from denominator→ 30
but this can be simplified further with a GCF of 5 

answer with new GCF is 1/6
hope this helps

Y^-3/y^-1 rewrite with positive exponetents

Answers

Answer:

Y/Y^3

Step-by-step explanation:

Negative exponents work like this: Y^-1 = 1/Y

We can apply this concept to our problem. Y^-3 would be 1/Y^3, and that is divided by 1/Y, so we flip the Y onto the numerator from the denominator and so we get Y/Y^3.
