Answer:

The correct answer is option  C - 40°

Step-by-step explanation:

From the figure we can see a circle.

CD and CE are the two tangents from a common external point C.

CD = CE

<u>To find the measure of <DCE</u>

Consider the quadrilateral <DAE.

<D = <E = 90°  [ Angles made with tangent and radius]

m<DCE + m<DAE = 180°

m<DCE = 180- m<DAE

 = 180 - 140

 = 40°

The correct answer is option  C - 40°

There is:
trapezoid
A = 0.5(3.2+6.5)4.5
= 21.825

triangle
A = 0.5(2.7)4.5
= 6.075

rectangle
A = 1.8(4.5)
= 8.1

Total Area = 21.825 + 6.075 + 8.1
= 36

when camping alone , mr adam uses all of the water in 12 days, then when mrs adams and mr adams camp together they use all of th
professor190 [17]

Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.

<h3>What is the together rate?</h3>

The together rate is the sum of each separate rate.

In this problem, the rates are:

  • Together: 1/8.
  • Mr Adam: 1/12.
  • Mrs Adams: 1/x.

Hence:

\frac{1}{12} + \frac{1}{x} = \frac{1}{8}

\frac{x + 12}{12x} = \frac{1}{8}

12x = 8x + 96

4x = 96

x = \frac{96}{4}

x = 24

If Mrs Adams camps alone, she will use all the water in 24 hours.

A container ship left port last week caring some good weighing a total of 125,890 tons today I stopped in another port to unload
11Alexandr11 [23.1K]

Answer:

Step-by-step explanation:

You need to be specific.  Did the weight decrease by 60 tons or 60 pounds?  I assume tons, but in math, you can't assume.

This problem seems overly simple, so I am wondering if some information is missing.  With the given information and assuming the decrease was in fact 60 tons, you would have:

125,890 - 60 = 125,830 tons
