Identify at least one pair of the following angles

Dahasolnce [82]

Answer:

Alternate exterior angles : ∠g = ∠b , ∠h = ∠a (opposite sides and on outer side)

Alternate interior angles : ∠c = ∠f , ∠e = ∠d (opposite sides and on inner side)

Consecutive interior angles : ∠c = ∠e , ∠d = ∠f (same sides and on same line)

Corresponding angles : ∠e = ∠a, ∠f = ∠b, ∠g = ∠c, ∠h = ∠d (same sides on the line)

Linear pairs : ∠c and ∠e, ∠d = ∠f, (they add to 180)

Vertical angles : ∠c =∠b, ∠d = ∠a, ∠g=∠f, ∠e = ∠h (vertical angles)

Franco read 3/8 of a chapter of his history book in 1/5 of an hour. At this rate, how many chapters of his history book can he r

Irina18 [472]

He can read $1\frac{7}{8}$ chapters of his history book in 1 hour.

Explanation

Franco read 3/8 of a chapter of his history book in 1/5 of an hour.

Suppose, he can read $x$ chapters of his book in 1 hour at this rate.

So, the equation according to the ratio of 'the chapter to the time' will be....

$\frac{x}{1}= \frac{\frac{3}{8}}{\frac{1}{5}}\\ \\ \frac{x}{1}=\frac{3}{8}*\frac{5}{1}\\ \\ \frac{x}{1}=\frac{15}{8} \\ \\ x= \frac{15}{8}= 1\frac{7}{8}$

So, he can read $1\frac{7}{8}$ chapters of his history book in 1 hour.
