Un numar este divizibil cu 18, daca el este divizibil cu 2 si cu 9...ca sa fie divizibil cu 2 trebuie sa aiba ultima cifra para, iar ca sa fie divizibil cu 9, trebuie sa aiba suma cifrelor un multiplu de 9.

Examine the diagram at right. The smaller triangle (inside of the larger triangle) is similar to larger triangle. How can you so
olchik [2.2K]

As the exercise says, the triangles are similar. So, we can set up proportions between correspondent sides.

In order to solve for x we can set up the proportion between the horizontal and vertical sides:

28\div 11.2 = 27+x \div x

Solving this proportion for x implies x=18

Now you can solve for m and p using the pythagorean theorem, because both triangles are right:

m = \sqrt{18^2+11.2^2} =21.2

Then, we know that the hypothenuse of the big triangle is m+p, so we have

m+p=\sqrt{(18+27)^2+28^2} = 53

which implies

p = 53-p = 53-21.2=31.8

What is the lcm of 16, 24 and 40
ivann1987 [24]
The answer is 240

Explanation: The Least Common Multiple (LCM) is the smallest number that two or more numbers will divide into evenly. NOTE: to find LCM you first need to know how to find GCD.

First we will find LCM for first two numbers ( 16 and24 ).

Step 1: Find the GCD (Greatest Common Divisor ) of 16 and 24 which is 8.

Step 2: Multiply the numbers 16 and 24 together ( 16 * 24 = 384 )

Step 3: Divide the 384 with 8. (384/8 = 48)

So, the LCM of 16 and 24 is 48.

Now we will find the LCM of above result (48) and third number ( 40 ) using the same procedure.

The result of this part is 240

Use the relationship between the angles in the
erastovalidia [21]

The 3 angles when added together make a straight line which is 180 degrees. To find x subtract the 2 known angles from 180.

The answer would be x = 180 - (67 + 52)

What is 33/7 as a mixed number
melamori03 [73]
33/7 is an improper fraction. 

To make it a mixed fraction, do this:-

How many times does 7 go into 33?

About 4 times.

4*7 = 28

4 is our whole number.

Now, subtract to get the numerator. 

33-28 = 5

4    5/7

Final answer:  4  5/7

a 32 foot ladder is leaned against a wall. if the base of the ladder is 8 feet from the wall, how high up the wall will the ladd
Leno4ka [110]

Answer:

31 feet

Step-by-step explanation:

Given: The length of ladder, leaned against wall= 32 foot

           The base of ladder is 8 feet away from wall

Adjacent= 8 feet and Hypotenuse= 32 foot

we need to find height of wall till the ladder reach (Opposite).

We will use Pythagorean theorem; hypotenuse^{2} = adjacent^{2} +opposite^{2}

⇒32^{2} = 8^{2} +opposite^{2}

⇒1024= 64+opposite^{2}

subtracting both side by 64

⇒ Opposite^{2} = 1024-64= 960

⇒Opposite= \sqrt{960} = 30.98 ≅ 31 ft

∴ 31 ft high up the wall.
