Answer:

10cm

Step-by-step explanation:

CDB and CEA are similar=>CD/CE=DB/EA=>5/9=DB/18=>

9DB=90

DB=10

The required length of DB in the diagram below is 10 cm.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

Given:

In the given triangle we have

СD=5 cm

DE= 4 cm

EA= 18 cm

According to given question we have

In a triangle CDB and CEA are similar

So,

[tex]\frac{CD}{CE} =\frac{DB}{EA}\\\\=\frac{5}{9} =\frac{DB}{18}\\\\=9DB=90\\\\DB=10[/tex]

Therefore, the required length of DB in the diagram below is 10 cm.

Step-by-step explanation:

A Parallelogram is known to be a flat shape quadrilateral which has four opposite sides Each two opposite sides are parallel and are equal in length. The opposite angles are equal.

The above answer is correct because opposite angles of a parallelogram are equal:

m∠CDA = m∠ABC

where m∠CDA = 63

∴ m∠ABC = 63 (answer)

Answer:

  41.7 nautical miles

Step-by-step explanation:

It can help to draw yourself a diagram. It will show you the desired distance is the hypotenuse of a right triangle with side lengths 36 and 21. The Pythagorean theorem can be used to find the distance of interest.

  d² = 36² +21²

  d² = 1296 +441 = 1737

  d = √1737 ≈ 41.6773

The ship is about 41.7 nautical miles from the starting point.

Solve the equation 2x2−5x+3=0 by the method of completing square.

Answer:

We have,

2x2−5x+3=0

⇒x2−25x+23=0 (Dividing throughough by 2)

⇒x2−25x=−23 (Shifting the constant term on RHS)

⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)

⇒(x−45)2=1625−23⇒(x−45)2=16

Answer:

580 seedlings altogether.

Step-by-step explanation:

Given that,

Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.

The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%

Let x = the total number of seedlings

[tex]15\%\ of\ x=87\\\\x=\dfrac{87\times 100}{15}\\\\x=580[/tex]

Hence, three boys plant 580 seedlings altogether.

Answer: 18 feet

Step-by-step explanation:

Well, first we need to find the circumference because that is the outside of the pipe.

Circumference = 2 x Pi x Radius

Radius is half of diameter.

So we plug in all the values in to the formula.

2 x Pi x 6 inches = Circumference

12Pi = 37.69911184 inches

37 inches to feet = about 3 feet.

3 x 6 = 18 feet.

Answer:

x=2.5

Step-by-step explanation:

1/2(6x-10)-x=0 Replace the ? with a 0 so you can solve for x.

So your going to want to distribute everything in parentheses by 1/2 first to get 3x-10-x=0 Next your going to simply the equation by combining like terms to get 2x-5=0. Next add five to both sides so that 2x=5. Finally divide both sides by 2 and the answer is x=2.5.

Hope this helped!
