Answer:

205°

T(t) = 65°+20°t

Step-by-step explanation:

Let the temperature be T and time be t

<u>The equation to determine the temperature T after t minutes is:</u>

  • T(t) = 65° + 20°t

<u>For t = 7 we get:</u>

  • T(7) = 65° + 20°*7 = 65° + 140° = 205°

sergeinik [125]

Given that Trent's watch runs at half the speed it should run, this implies that

for every hour passed, his watch moves by half an hour.

Hence, for every half-hour passed, Trent's watch moves by 15 minutes.

Hence, when the real time is 10:30 am, Trent's watch will show 9:15 am.

You can either do;


1. 90(2) = 100(2)

180 = 200


In 3 minutes, they can write 200 words. So now we can divide by 3.

3/3 = 1 minute

200/3 ≈ 66.666


or


2. 90/3 = 30 secs

100/3 ≈ 33.333


30(2) = 1 minute

33.333(2) ≈ 66.666


Either way, the admin assistant can write 67 words per minute. (Rounded to the nearest whole)

Together, the areas of the rectangles sum to 30 square centimeters.
Juli2301 [7.4K]

Answer:

3x+2y

Step-by-step explanation:

Find the rectangles attached

Area of a rectangle = Length * Width

A = A1+A2

given

A = 30cm²

A1 = 3 * x

A1 = 3x

A2 = 2*y

A2 = 2y

Substitute

30 = 3x+2y

Hence the required equation is 3x+2y = 30
