9 hours
Step-by-step explanation:
$273/13 hours=$21 per hour
$189/$21 =9 hours
53). 100 servings / 20 people = (100/20) (svngs/ppl)
= 5 servings per person.
Each person gets 1/20 = 5% = 0.05 of the pan.
54). 100 servings / 40 people = (100/40) (svngs/ppl)
= 2.5 servings per person.
Each person gets 1/40 = 2.5% = 0.025 of the pan.
55). 100 servings / 30 people = (100/30) (svngs/ppl)
= (3 and 1/3) servings per person.
Each person gets 1/30 = (3 and 1/3) % = 0.0333... of the pan.
Answer:
5
Step-by-step explanation:
this can be solved using simultaneous equation
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2
Multiply equation 2 by 2
2a + 8b = 34 equation 3
Subtract equation 1 from 3
5b = 15
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
2a = 10
a = 5
Answer:
2 rooms
Step-by-step explanation:
1/2 divided by 1/4 is 2

Answer - 2
The answer is A in both cases. Changing the units does not change the measurement, only the number representing the measurement. (Some numbers are easier to work with than others, which is why some units are preferred for certain measurements.)
Question 1.
A. <span>The surface area stays the same, but the number representing the surface area decreases.
Question 2.
</span><span>A. The surface area stays the same, but the number representing the surface area increases.
