Find the Missing Numerator and Denominator

n200080 [17]

Answer:

missing denominator: 5

missing numerator: 3

Step-by-step explanation:

You know the product of fractions is formed by multiplying numerators and multiplying denominators.

$\dfrac{3}{d}\times\dfrac{n}{4}=\dfrac{3n}{4d}=\dfrac{9}{20}$

This gives rise to two equations:

3n = 9 ⇒ n = 3

4d = 20 ⇒ d = 5

The missing denominator is 5; the missing numerator is 3.

$\dfrac{3}{5}\times\dfrac{3}{4}=\dfrac{9}{20}$

If you had a right triangle with legs measuring 40 yards and 100 yards long,

tia_tia [17]

9514 1404 393

Answer:

Step-by-step explanation:

For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...

c² = a² +b²

Solving for c, we have ...

c = √(a² +b²)

c = √(40² +100²) = √(1600 +10000) = √11600

c ≈ 107.70 . . . . yards

The length of the hypotenuse is about 108 yards.
