20 = (116- BC)/2
multiply both sides by 2:
40 = 116 - BC
BC = 116 -40
BC = 76

Answer:
15 seconds
Step-by-step explanation:
Put the given heights in the equation and solve for t.
h(t) = -16t² +3600
0 = -16t² +3600 . . . . h(t) = 0 at ground level
16t² = 3600 . . . . . . . add 16t²
t² = 3600/16 = (60/4)² = 15² . . . . . divide by 16
t = 15 . . . . . . . . . . . . take the square root
It will take 15 seconds for the phone to hit the ground.
The values In wxyz are mathematically given as
W=4
y=5
X=0
<h3>What is the values In
XYZ?</h3>
- My one's digit and my tens digit together make up a total of seven.
- My one digit has three more digits than my tens digit does.
Let the equation for the number be: wxyz.
- Digits at tens place = yz
- Diglt at ones place = z
Generally, the equation for is mathematically given as
z+y=7 ......1
y=2+3 .......2
solving further
z+3+z-7
2z 7-3
z=2
Putting the value of z Within the second equation:
y=z+3 y=2+3
y=5
1. The digit in the thousands place of my number is 4, and
2. The digit in the hundreds place is four fewer than the digit in the thousands place.
W=4
X=w-4
x=4-4
X=0
In conclusion, the values In wxyz are
W=4
y=5
X=0
