Answer:

The volume of an irregular shape can be found by placing it in a can (of known volume) of water. The amount of water the shape displaces is equal to its volume.

Boat will float. It has a lower density that that of water.

Step-by-step explanation:

If an object has a lower density than the fluid it is in, it will float. If higher, it will sink.

Assuming the water is at room temperature:

Density of water,p_{w}=1000kg/m^3

Density,   p = \dfrac{m}{V}

Mass of boat=19,000,000

Volume of boat=45,000m^3

p_{b}=\frac{19,000,000kg}{45,000m^3}\\p_{b}=422.22kg/m^3

p_{w}>p_{b}

Therefore the boat will float on water.

#4. Find the value of x and use it to find the length of<br> CE, BD, and BE<br> Find BD.
almond37 [142]

Answer:

  • x = 8
  • 12 = BD
  • 23 = BE
  • 13 = CE

Step-by-step explanation:

<u>We know that:</u>

  • BD = 2x - 4
  • DE = 2x - 3 - 2
  • BE = 3x - 1
  • CE = 2x - 3

<u>Solution:</u>

  • (2x - 4) + (2x - 3 - 2) = 3x - 1
  • => 2x - 4 + 2x - 3 - 2 = 3x - 1
  • => 4x - 9 = 3x - 1
  • => 4x - 3x = 9 - 1
  • => x = 8
  • => 2x - 4 = BD
  • => 2(8) - 4 = BD
  • => 16 - 4 = BD
  • => 12 = BD
  • => 3x - 1 = BE
  • => 3(8) - 1 = BE
  • => 24 - 1 = BE
  • => 23 = BE
  • => 2x - 3 = CE
  • => 2(8) - 3 = CE
  • => 16 - 3 = CE
  • => 13 = CE

Hence, the answers are:

  • x = 8
  • 12 = BD
  • 23 = BE
  • 13 = CE

Someone please answer this, I would really be appreciative.
Iteru [2.4K]

Answer:

y-30 = 3(x-1)

Step-by-step explanation:

Point-slope form of an equation is

y-y1 = m(x-x1)  where (x1,y1 ) is a point and m is the slope

We know on day 1 they exercised 30 minutes (1,30) where x is the number of days and y is the minutes.  The rate increased 3 minutes each day so m = 3

y-30 = 3(x-1)

Find m&lt;2<br> See picture for full problem. Please and thank you!
aev [14]

Step-by-step explanation:

as the other triangle is Isosceles triangle which means it's two sides are equal and two angles are equal so

to find its 3rd angle apply angles sum property on it

according to which

2(68) + x = 180

136 + x = 180

x = 180 - 136

x = 44°

also we know, the other triangle is right angled triangle

so, it's one angle is 90° and 2nd angle is 44° (Vertically opposite angle)

therefore to know measure of angle 2 apply angle sum property of triangle in it too.

so,

90 + 44 + angle 2 = 180

134 + angle 2 = 180

angle 2 = 180 - 134

angle 2 = 46°

therefore, angle 2 is 46°

hope this answer helps you dear!
