It is worked out that if 4 ladles full of soup are given to each person, 120 people can be fed. The customers have complained in

alina1380 [7]

Answer:

$80\ people$

Step-by-step explanation:

Per person available ladles full of soup $=4$

Total number of persons $=120$

Hence total number of ladles full of soup $=120\times 4=480$

Now per person available ladles full of soup $=6$

Total number of persons that can be fed

$=\frac{total\ availability}{per\ person\ requirements}\\\\=\frac{480}{6}\\\\=80$

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AH=4 and HC=1, find BH.

Rudik [331]

Answer:

Length of BH is 2 units.

Step-by-step explanation:

We have, ΔABC with ∠ABC = 90° and an altitude BH.

Also, it is given that the length of sides AH is 4 units and HC is 1 units.

Since, the 'Altitude Rule' states that 'the length of the altitude is the geometric mean of the line segments it bisects'.

So, we get that,

$BH^{2}=AH\times HC$

i.e. $BH^{2}=4\times 1$

i.e. $BH^{2}=4$

i.e. $BH=\pm 2$

Since, the length of the side cannot be negative.

So, length of BH is 2 units.
