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.
Answer:
0∙2=0
Step-by-step explanation:
Zero Property of multiplication is as follows :
The product of a number and 0 is equal to 0.
In option (c), 0 is multiplied by 2 and as a result, we get 0 as the answer.
It means,
0∙2=0
Hence, option (c) i.e. 0∙2=0 shows the Zero Property of Multiplication.
The least common denominator is 2
Answer:
160 days
Step-by-step explanation:
If it takes 8 days with 10 women to make 3 tree houses, then the rate of woman per tree house is 3/80. Multiplying this by 6 and dividing by 36, you get a rate of 1/160 or 160 days. Hope this helps!
The answer is the second one. 5.2 repeating.
