Please I need help and the calculation of which contract is better.
kramer

Answer:

You should go with the 1st, because it's cheaper.

Step-by-step explanation:

1st plan:

30$ which include 75 mins of free calls and 100 free text messages

25 more mins * 10¢ /min(0.1$/min) = 2.5$

You will pay 32.5$

2nd plan:

(calls)100*0.3$=30$

(text messages)100 * 0.1$=10$

30+10 = 40$

Identify the terms and like terms in the expression 14 – 8x– 6 - 10x.
grin007 [14]

Answer:

Like terms are similar and terms are different.

Like terms :-

  • -10
  • 14
  • -6

They are similar.

Terms :-

  • -8x²
  • -10x

One has an exponent and other does not which means they are not like terms and are only terms.

Hope this helps, thank you :) !!

Two fences in a field meet at 120 degrees. A cow is tethered at their intersection with a 15-foot rope, as shown in the figure.
bija089 [108]

Answer:

Area of the field that the cow graze  = 235.71 sq. ft

Step-by-step explanation:

Area of the field that the cow graze = (120 / 360) * πr²

   = (1/3) * (22/7) * 15 * 15

   = (22 * 5 * 15) / 7 =  1650 /7

   = 235.71 sq. ft
