The formula y = 64h gives the velocity v in feet per second of an object that has fallen h feet. Find thevelocity of an object that has fallen 92 feet. Round to the nearest hundredth.
Answers
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

First, since the fractions carry the same denominator (luckily), we can easier combine the first two fractions, resulting in having to add the numerators.
Second, our next step is to multiply both sides by 7. Our goal is to get the variable (x) by itself on one side of the problem, so we have to do everything on the other side.
Third, let's simplify 4/7 × 7. To do so, we multiply the whole number by the numerator. Basically, 7 × 4 = 28.
Fourth, we can now simplify 28/7. To do this, we can ask ourselves, what can multiply into 7 to equal 28? 7 ÷ 28 = (4), so 4 is our answer for this.
Fifth, we can continue doing everything on one side. We will need to subtract 5 from each side.
Sixth, let's simplify 4 - 5, which is easily -1. Our problem will look like 3x = -1, but we have one more step to do. Our last step is to divide each side by 3. This will create a fraction. Our fraction will be negative because we carried our -1 over.

0.1 = x
100 10
When you cross-multiply, this becomes (0.1)(10) = 100x
0.1 times 100 equals 1, so it becomes 1 = 100x
To get x by itself, divide both sides by 100, and you get x = 0.01 fluid ounces

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
