Dennis read 30% of his book on Tuesday and of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?

1/2x

Step-by-step explanation:

Dennis read 30% of his book on Tuesday and 1/5 of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?

Total pages of the book = x

Tuesday = 30%

= (30/100)x

= 3/10x

Wednesday = 1/5x

3/10x + 1/5x

= 3x+2x/10

= 5/10x

= 1/2x

what fractional part of the book did he have left to read after Wednesday

= x - 1/2x

= 2x-x/2

= x/2

= 1/2x

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
