Is 10% of 10% of 100 the same as 20% of 100

Answer:

Letters O and E have lines of symmetry ! Vertically & horizontally

Question:

1) The kick is good! The ball passes about 10 feet above the crossbar.

2) The kick is good! The ball clears the crossbar by approximately 14 feet.

3) The kick is good! The ball clears the crossbar by about 4 feet.

4) The kick is not successful. The ball is 2 feet too low.

Answer:

The correct option is;

3) The kick is good! The ball clears the crossbar by about 4 feet.

Step-by-step explanation:

Here we have

Horizontal distance from goal, x = 36 yards = 108 ft

Vertical distance of goal, y = 10 ft

Angle of elevation of ball = 34°

Initial velocity of ball, v₀ = 68 ft/s

∴ Vertical component of velocity = = v₀×sin(θ₀)×t - g×t

Horizontal component of velocity = vₓ = 68×cos(34) = 56.375 ft/s

The equation for projectile motion is as follows

x = x₀ + v₀×cos(θ₀)×t

y = y₀ + v₀×sin(θ₀)×t - 1/2×g×t²

Where:

x₀ = Initial horizontal displacement of the ball = 0

y₀ = Initial vertical displacement of the ball = 0

t = Time of flight of the ball

Therefore;

108 = 0 + 68×cos(34)×t which gives;

t = 108/56.375 = 1.916 seconds

Hence, y = y₀ + v₀×sin(θ₀)×t - 1/2×g×t² gives;

y = 0 + 68×sin(34)×1.916 - 1/2×32.2×1.916²

y = 72.85 - 59.09 = 13.76 ft, hence the vertical location of the ball at 36 yard is 13.76 ft where the crossbar is at 10 ft hence the ball clears the crossbar by 13.76 ft - 10 ft = 3.76 ft ≈ 4 ft

Therefore, the kick is good! The ball clears the crossbar by about 4 feet.

Answer: 8(3-2x)(x+5), -16x^2-56+120, x=-5, or x=3/2.

Step-by-step explanation:

First convert the multi fraction into multiplication: 8(3-2x)(x+5)

Then simplify: -16x^2-56+120

If you want, you can solve for x, which gets you x=-5, or x=3/2.

I hope this helps! :P

Step-by-step explanation:

Johanna is buying 1 1/2 at the same price as Brandi. Multiply the total price by 1 1/2 to find the price.

6.96=1 dozen

x=1 1/2 dozen

x=$10.44

Answer:

If Wyatt can husk at least 12 an hour, then to work out how much 72 takes, we do 72 ÷ 12 to find out the time. The answer is 6.

If Wyatt can husk 18 at most, then we do 72 ÷ 18 = 4 hours.

Wyatt can husk 72 dozen ears in anywhere between 4 and 6 hours, but if you were to average it, you would get 5 hours. ((4 + 6) ÷ 2 = 5).

Answer: and .

Step-by-step explanation:

Since, we have number with help of  which we have to find a square.

If we divide 9 by 9 then we will obtain 1 which is itself a square.

That is,  

Now, If we multiply 9 by itself we obtain 81, which is the square of 9.

That is,

Note: We can also make other squares by using number 9.
