A portion of the Quadratic Formula proof is shown. Fill in the missing statement. Statements Reasons x squared plus b over a tim

es x plus the quantity b over 2 times a squared equals negative 4 times a times c all over 4 times a squared plus b squared over 4 a squared Find a common denominator on the right side of the equation x squared plus b over a times x plus the quantity b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Add the fractions together on the right side of the equation the quantity x plus b over 2 times a squared equals b squared minus 4 times a times c all over 4 times a squared Rewrite the perfect square trinomial on the left side of the equation as a binomial squared ? Take the square root of both sides of the equation x plus b over 2 times a equals plus or minus the square root of the quantity b squared minus 4 times a times c end quantity, all over 4 times a squared x plus b over 2 times a all squared equals plus or minus b squared minus 4 times a times c, all over 4 times a squared all squared the square root of x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 4 times a squared x plus b over 2 times a equals plus or minus the square root of b squared minus 4 times a times c, all over 4 times a squared

Eva has £6.05 in her moneybox.
PIT_PIT [208]

Answer:

11 of 20p, 22 of 10p and 33 of 5p

Step-by-step explanation:

Eva has 20p, 10p and 5p coins, total of £6.05 = 605p

Let 20p=x, 10p=y, 5p=z

<u>Then</u>:

  • 20x + 10y + 5z = 605
  • y : x = 2 : 1 ⇒ x= y/2
  • y : z = 2 : 3 ⇒ z= 3y/2

<u>Rewriting the first equation considering next two:</u>

  • 10y + 10y + 7.5y = 605
  • 27.5y = 605
  • y= 605/27.5
  • y= 22
  • x= y/2 = 22/2 = 11
  • z = 3y/2 = 3*11 = 33

<u>Answer:</u> 11 of 20p coins, 22 of 10p coins and 33 of 5p coins

A skydiver falls 144 feet in 3 seconds. How far does the skydiver fall per second?
Mekhanik [1.2K]
If a skydiver falls 144 feet in 3 seconds in you need to find the time per second that they’re falling, you would simply have to get the time per one second. You have to get the 3 to one, so you would divide by 3 on both sides, getting 48 feet per second. (assuming they fell at the same rate all 3 seconds)

A rectangle is 3 times as long as it is wide. the perimeter is 16 feet. find the dimensions ​
astraxan [27]

Answer:

Width = 2 feet

Length = 6 feet

Explanation:

Variables:

Perimeter = p

Length = l

Width = w

Equation:

2w + 2l = p

It is given that:

l = 3w

and

p = 16 feet

With this information, we can rewrite the equation (substitute)

2w + 2(3w) = 16

Simplify

2w + 6w = 16

Add

8w = 16

Divide both sides of the equation by 8

Width = 2 feet

Length = 3(w) = 3(2) = 6 feet

Hope this helps :)

What the length of the hypotenuse
Free_Kalibri [48]

Answer:

73.43

Step-by-step explanation:

To find any hypotenuse use the Pythagorean theorem:a^{2} +b^{2} =c^{2}

  • First, square 36 (which would be 36 x 36) and square 64 (64 x 64).
  • Add them together.
  • Find the square root of the total.
  • That's your answer :)
  • Or you can just run it through this: https://www.google.com/search?q=how+to+calculate+hypotenuse&oq=how+to+calculate+hypot&aqs=chrome.0.0j69i57j0l6.8070j0j7&sourceid=chrome&ie=UTF-8
