It should be 3 bookshelves. You put 3 of the math books on each one, then two reading books on each one. Hope this helps
Answer:
D. $53.76.
Step-by-step explanation:
20% = 0.20 as a decimal.
Price before Sales Tax = 64 - 0.20*64
= $51.20
Adding 5% sales tax we get
52.20 + 0.05*51.20
= $53.76 (answer).
Answer:
25
Step-by-step explanation:
Given
37 - (9 + 4) + 6 ÷ 6 ← evaluate parenthesis
= 37 - 13 + 6 ÷ 6 ← perform division
= 37 - 13 + 1 ← evaluate from left to right
= 24 + 1
= 25
Answer:
d) 135º
Step-by-step explanation:
Note that the angle DCU is the sum of the angles DCB and BCU. The angle DCB is 90º because A B C D is a square, then all its angles are equal to 90º.
After attaching B U C to A B C D, we obtain a trapezoid A U C D. Since A U C D has at least one pair of parallel sides, then AU should be parallel to CD, thus the angle CBU must be 90º.
B U C is isoceles, so we conclude that other two angles must have the same size, and due to the sum of the angles of a triangle being 180º, then both BUC and BCU are equal to 45º
As a result, the angle DCU is equal to 90º+45º = 135º. Option d is the correct one.
