Answer:
45 cm^2
Step-by-step explanation:
The area of a triangle can be found using:
a= (b*h)/2
We know the base is 18 cm and the height is 5 cm. Therefore, we can substitute 18 in for b, and 5 in for h.
a=(18*5)/2
Multiply 18 and 5 first
a=90/2
Divide 90 by 2
a=45
So, the area is 45 cm^2
The number of combinations of 2 health care providers of different types possible are 47.
<u>Explanation:</u>
<u></u>
Doctors = 4
Dentists = 3
Nurses = 5
combinations of two different health care providers = ?
Combination would be = ⁴C₁ X ³C₁ + ³C₁ X ⁵C₁ + ⁴C₁ X ⁵C₁
ⁿCₐ = n! / ( n - a )! X a!
So on calculating the combination we get,
= 4 X 3 + 3 X 5 + 4 X 5
= 12 + 15 + 20
= 47
Therefore, the number of combinations of 2 health care providers of different types possible are 47.

Answer:
- 5/6
Step-by-step explanation:
turn it into an improper fraction.
1 and 2/3 = 5/3
2 and 1/2 = 5/2
5/3 - 5/2 = 10/6 - 15/6
= -5/6
