Answer:
The velocity of the object is 76.73 ft/sec
Step-by-step explanation:
* Lets explain how to solve the problem
- The formula y = √(64h) gives the velocity y in feet per second of an
object that has fallen h feet
- To find the velocity of an object that has fallen 92 feet substitute h
by 92 in the formula
∵ y = √(64h)
∵ h = 92 feet
∴ y = √64(92) = √5888 ≅ 76.73 feet/seconds
* The velocity of the object is 76.73 ft/sec

b. (z:z < 24)
c. (z:z > 24)
d. (z:z >24)
6z+5>35
Subtract 5 from both sides
6z+5-5>35-5
6z > 30
Divide both sides by 6
6z/6 > 30/6
z > 5

Answer:
Step-by-step explanation:
2x−y=3..........(1)
7x−2y=3........(2)
Making y as subject in equation (1)
y = 2x - 3
Substituting y into (2)
7x - 2(2x - 3) = 3
Opening bracket
7x - 4x - 6 = 3
3x = 3 + 6
3x = 9
x = 9/3
x = 3
And y = 2x - 3
y = 2(3) - 3
y = 6 - 3
y = 3
7 % of cost price is 2.80 , What about 1%?
7 = 2.80
1 = x (where x is the price value of 1% in dollars)
We simplify the above equation, so:
7 × x = 2.8 × 1 → 7x = 2.8 → x = 2.8 / 7 → x = 0.4 dollars
We know that 100% represents the whole price,
so if 1% is 0.4 dollars, then 100% will be 0.4 × 100 = 40 dollars
Therefore the store charged $40 dollars for the helmet before tax
