Answer:
6
Step-by-step explanation:
1 meter is 100 centimeter, as "centi" means 1 hundredth:
So 100 centimeter means 100-"1 hundredth" meters, which is 1 meter.
In short, since 1 meter is 100 centimeters, 8 meters are 800 centimeters.
Answer: 800 cm
Answer:
As per the statement:
The path that the object takes as it falls to the ground can be modeled by:
h =-16t^2 + 80t + 300
where
h is the height of the objects and
t is the time (in seconds)
At t = 0 , h = 300 ft
When the objects hit the ground, h = 0
then;
-16t^2+80t+300=0
For a quadratic equation: ax^2+bx+c=0 ......[1]
the solution for the equation is given by:

On comparing the given equation with [1] we have;
a = -16 ,b = 80 and c = 300
then;


Simplify:
= -2.5 sec and
= 7.5 sec
Time can't be in negative;
therefore, the time it took the object to hit the ground is 7.5 sec
Knowing 1+7 helps you find the sum of 7+1 because 1+7 and 7+1 is communitive property of addition. Also because 1+7 is the same answer as 7+1.
Ex:
1+7=8
And
7+1=8
its the same result.
Answer:
x = 4
Step-by-step explanation:
17x-8=60 (this is an equilateral triangle, therefore all the angles should be 60 degrees)
17x-8=60
+8 +8
17x=68
/17 /17
x=4
