What is the missing numerator in the equivalent fraction? The mixed number 3 one-half is equivalent to a fraction with a denomin
Alex

7 is the missing numerator in the equivalent fraction with a denominator of 2.

<u>Step-by-step explanation</u>:

The mixed fraction is 3 1/2.

  • Convert it into a proper fraction to get a equivalent fraction.
  • Multiply the denominator 2 with 3 and then add 1 to the answer.

⇒ 3 1/2 = ((3\times2) + 1)/2

⇒ 3 1/2 =7/2

∴ The numerator of the equivalent fraction is 7.

4. A 25-foot ladder is placed against the side of a building with the bottom of the ladder 7 feet from the
faltersainse [42]

Answer:

Step-by-step explanation:

The questions asks for how far down the wall does the ladder move, so to say that in another way,   what is the difference between when the ladder is taller up the wall and when it is shorter up the wall.

so figure out what the height of the ladder is up the wall for each of the situations.

1) Taller

we are told the Hyp and the Adj sides of the triangle

so  use  SOH CAH TOA to remind how trig functions fit on the triangle  sin = Opp / Hyp , Cos=Adj / Hyp ,  Tan = Opp / Adj  so

Cos(Ф) = 7 / 25

Ф = arcCos( 7/25)

Ф = 73.739795 °

then use

Sin( 73.739795 ) = Opp / 25

25* Sin( 73.739795 ) = Opp

24 = Opp

2) Shorter

Cos(Ф) = 15 / 25

Ф = arcCos( 15 / 25 )

Ф = 53.13010 °

sin( 53.13010 ) = Opp / 25

25 * sin( 53.13010 ) = Opp

20 = Opp

now you know the two heights up the wall. so subtract the shorter from the taller

24 - 20 = 4

the ladder moves 4 feel down the wall  :)

If x + y = 4 and x2 − y2 = 64, what is the value of (x − y)?
murzikaleks [220]

The value of (x-y) is 16

Further explanation:

We have to use the given values to find the value

Given

x+y=4\\and\\x^2-y^2=64

We will use:

x^2-y^2=64

Simplifying by using: x^2-y^2=(x+y)(x-y)

So,

(x+y)(x-y)=64

As we know that x+y=4

Putting the value in equation

(4)(x-y)=64

Dividing both sides by 4

\frac{4(x-y)}{4}=\frac{64}{4}\\x-y=16

The value of (x-y) is 16
