<h3>Answer:  34.95</h3>

=======================================================

Explanation:

The upper boundary, or upper bound, is a fence of sorts.

Note how the following values all round to 34.9, when rounding to one decimal place

  • 34.94
  • 34.945
  • 34.949
  • 34.9499
  • 34.94999
  • 34.949999
  • 34.9499999
  • 34.94999999

We can keep going with the pattern of 9s at the end and whatever value you form will still round to 34.9; so you can see that there is no largest value we can reach that will round to 34.9

All of those values are slowly approaching 34.95, which is the upper fence I mentioned. We can get closer and closer to this value, but we can't actually reach it. Otherwise, 34.95 will round to 35.0

Rectangle abcd is similar to rectangle pqrs given that ab =14cm bc =8cm and pq=12cm calculate the length of qr
ohaa [14]

Answer: 6.8571 (Round as needed)

Hope this is correct

Step-by-step explanation:

This is a simple ratio problem

Using the similarity statement we can say 14:12, (ab:pq)

That is our ratio.

So we do 14/12 = 8/x, we solve this using algebra to get our answer.

Hope this is correct.

Why is (3,4),(5,10),(3,12) not a function
jasenka [17]
A function has a property such as "one input must be mapped to exactly one output." An input is the x-value, and the output is, generally, the y-value. In this set of points above, the input 3 maps to 4 <em>and </em>12, and therefore is not a function.

Answer correct and u get brainliest if u are able to answer this u r a math god
babunello [35]

Answer:

184ft^2

Step-by-step explanation:

W have to find the area of triangles and rectangles and add them together to get the total area of the figure:

Area of triangles = 1/2(b)(h)

Area of rectangles = l x w

6 x 10 = 60

1/2(6)(4) = 12 (We can make this 12 a 24 because there are two of these triangles)

5 x 10 = 50 (We can also make this 50 a 100 because there are two of these rectangles)

100 + 24 + 60 = 184ft^2
