if each student costs 1.25 dollars for their meal then you do 150 times 1.25 and get 187.5
Answer:
Step-by-step explanation:
Area of a triangle is 1/2 * b * h
b = base, the one labeled b on the diagram
h = height, the dotted line in the middle
so, you do pythagorean theorem with a and b to find the dotted line
a² + b² = h² (h is for height)
h = 
Then, you just plug in the numbers from question 3 to find h and then you do
1/2 * b * h
Answer:
80
Step-by-step explanation:
If we assume the triangles are similar and are isosceles, and that BK is an altitude, then we can work the problem.
Triangle OKN will be similar to triangle BKA, so ...
AN : AK = BO : BK = 1 : 3
Then ...
AN : AK : KC = 1 : 3 : 3
In terms of ratio units, ...
AN = 1
AC = 3+3 = 6
NC = 6-1 = 5
This means NC : AC = 5 : 6. The triangle perimeters will have the same ratio.
perimeter(NMC) = 5/6·perimeter(ABC) = 5/6·96
perimeter(NMC) = 80
