Look at this triangle. B 8 cm A 22 cm Work out length AB.

brilliants [131]

Answer:

23.41cm

Step-by-step explanation:

Using Pythagoras theorem

a²+b² = c²

Where a and b are sides of the triangle and c is the Hypotenuse.

If we substitute the values

B= 8 cm

A= 22 cm

22²+8² = c²

484 + 64= c²

√548 = c

C= 23.41

Hence, length AB is 23.41cm

A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people

Anastaziya [24]

Answer:

$\frac{1}{4} lbs/person$

Step-by-step explanation:

Here is the complete question: Find the rate of change for the situation:

A chef cooks 9 lbs of chicken for 36 people and 17 lbs of chicken for 68 people.

Given: 1st situation, A chef cook 9 lbs chicken for 36 people.

2nd situation, chef cook 17 lbs chicken for 68 people.

∴ 1st situation, weight of chicken per person= $\frac{9\ lbs}{36\ person} = \frac{9}{36}$

Weight of chicken per person= $\frac{1}{4} lbs/ person$

2nd situation, weight of chicken per person= $\frac{17\ lbs}{68\ person} = \frac{17}{68}$

Weight of chicken per person= $\frac{1}{4} lbs/ person$

In both the situation chef cook same amount of chicken per person, which is $\frac{1}{4} lbs/ person$

∴ Rate of change is $\frac{1}{4} lbs/ person$
