Answer:

<h2>The scale factor is 285.7143 ≅ 286.</h2>

Step-by-step explanation:

The square sheet has an area of 100 square meters.

Hence, the width of the sheet is \sqrt{100} = 10 meters.

The scale factor is needs to be in such a way, so that the film's wide will be match perfectly with the square sheet. Hence, 35x millimeters = 10 meters = 10000 millimeters .

x = \frac{10000}{35} = 285.7143.

3(x + 1) - 2x = -6    |use distributive property: a(b + c) = ab + ac

3x + 3 - 2x = -6

x + 3 = -6    |subtract 3 from both sides

ASAP! The graph shows outdoor temperatures (F) recorded one fall evening in Ohio. At what rate did the temperature change during
babymother [125]
Your answer would be D) -3°F/hour
Look at it this way...

47°F at 7:20pm
46°F at 7:40pm
45°F at 8:00pm
44°F at 8:20pm
43°F at 8:40pm

The temperature is going down by 1°F every 20 minutes so...

-1°F/20 minutes

Obviously there's no answer choice that says that so you'd need to change the minutes into an hour...

So an hour is 60 minutes and 60/20 = 3

So if you do 3・-1

You get the answer... -3°F/hour

Answer:

69.5

Step-by-step explanation:

Formula = 1/2 ( b1 + b2)h

base 1 + base 2 = 220

7645 x 2 = 14000 + 1200 + 80 + 10 = 15290

15290 / 220 =  764.5

H = 69.5

Lets check

1/2(220 x 69.5)

1/2(15290) = 7645

correct

If my answer is incorrect, pls correct me!
