Answer:
The model swing should be <u>2.75 cm</u> high.
Step-by-step explanation:
Given:
A 168-cm tall person is 2 cm in Ming’s model.
If the actual swing is 231 cm high.
Now, to find how high should his model swing be.
Let the model swing be 
So, 168 cm tall person is equivalent to 2 cm.
Thus, 231 cm actual swing is equivalent to 
model swing.
Now, we get the height of the swing in the model by using cross multiplication method:
<em>By cross multiplication:</em>
⇒ 
<em>Dividing both sides by 168 we get:</em>
⇒ 
Therefore, the model swing should be 2.75 cm high.
Answer:
Step-by-step explanation:
Given :
In the given quadrilateral ABCD,
BN and DM are the perpendiculars drawn to AC such that,
BN = DM
To prove:
Point O is the midpoint of segment BD.
Or
OD = OB
Solution:
In ΔOMD and ΔONB,
∠MOD ≅ NOB [Vertical angles]
∠M ≅ ∠N ≅ 90° [Given]
Therefore, by AA property of similarity,
ΔOMD ~ Δ ONB
Therefore, their corresponding sides will be proportional,
Since BN = DM,
OD = OB
Hence O is the midpoint of BD.
X=25
Step-by-step explanation:
- Because 5x5 =25, so the answer is x=25
Answer:
if you meant 105 instead of "10 5" the answer would be 697142.857143
Step-by-step explanation:
Hello There!
You divide 43 by 4:
43/4 = 10.75
It isn't a whole number.
Therefore, each employee would do approximately 11.
However, the exact amount is 10.75
Hope This Helps You!
Good Luck :)
