Answer:

3rd answer EF = 2√13

Step-by-step explanation:

Make a right triangle and use Pythagorean theorem a²+b² = c²

Go from point F 6 units down till point (1,-3) .From that point go 4 units left till you hit point E.

Triangle has legs a and b that are 6 and 4 units long so 6² + 4² = EF²

36 + 16 = 52

EF² = 52 find √52

EF = √52

There is no √52 as a whole number so rewrite 52 as a product of number who was a √ and the other who doesn't have a √

52 = 4 * 13

EF = √4 * √13 = 2√13

Richard can read 1/4 of a book in 4/5 of an hour.At this rate ,how much can richard read in one hour

Lisa [10]

Assuming that Richard always reads with the same rate, there is a direct proportion between the time spent reading and the portion of book read:

$\text{portion}_1 : \text{time}_1 = \text{portion}_2 : \text{time}_2$

So, we can set up and solve the following proportion:

$\dfrac{1}{4} : \dfrac{4}{5} = x : 1 \iff x = \dfrac{\frac{1}{4}}{\frac{4}{5}} = \dfrac{1}{4}\cdot \dfrac{5}{4} = \dfrac{5}{16}$
