Answer:
the backpack will be on the ground in 3 seconds but it will first make contact with the ground in 2.5 seconds
Step-by-step explanation:
the equation would be: y = -16t² + 100
if you solve for 't' then you will find the amount of time until it lands
0 = -16t² + 100
-100 = -16t²
100/16 = t²
t = √100/16
t = 10/4 = 2.5
8 squared = 64
so
(x/4)*2 = 64
divide x/4 by 2 to get x/2=64
now multiply both sides by 2 to get x=128
x = 128
Answer:
<em>No, 1 + 1 does not equal to 2.</em>
The Finger Explanation:
Simply, you have to use your fingers to count. 1 finger + 1 finger = 2 fingers. Therefore, your answer shall be 2 and not 11.
Answer:
x= 70 degrees
y= 30 degrees
z= 20 degrees
Step-by-step explanation:
Angle x will be supplementary to the 110 degree angle adjacent to it since it will form a straight line. 180 - 110 = 70 degrees.
Since we know the other two angle measures in the triangle that angle y is in, we can do 180 - (110 + 40) to find angle y. 180 - 150 = 30 degrees
We also know the other 2 angle measures of the triangle that angle z is in. We can find angle z by doing 180 - (70 + 90). 180 - 160 = 20
