Answer:
98
Step-by-step explanation:
for a 4 sided polygon you can only draw one diagonal from one vertex so it forms 2 triangles.
For 5 sides you get 3 triangles
For 6 sides - 4
For 7 sides - 5
For 8 sides - 6
Looks like we get 2 less triangles than the number of sides in the polygon
Answer for 100 sides is 98 triangles.
Answer:
B
Step-by-step explanation:
the first values represent the inputs, which are the x values and the other values are the outputs which are the y values
Y=mx+b (9,-6) x=9 y=-6
-6=(slope)9-10
9*4/9=4
4-10=-6
slope=4/9
y=4/9x-10
Answer: 168 hours
Step-by-step explanation:
There are 24 hours in a day. Thus, simply multiply 7*24 to get 168.
Answer:
Gia will need 2 liters of paint to cover her wall
Step-by-step explanation:
To get this, what we need to do at first is to calculate the area of the wall.
Mathematically since we have a rectangular wall, the area can be calculated by multiplying the length by the breadth.
Thus A = 4 * 5 = 20 M^2
Now from the beginning of the question, we were made to know that 1 liter will cover an area of 10 M^2
Thus, the amount in liters of paint that will cover an area of 20 M^2 will be 2 * 1 = 2 liters
