Refer to the diagram shown below.
Because quads WXYZ and BADC are congruent, therefore
WX = BA = 6 cm
XY = AD = 4 cm
YZ = DC
WZ = BC
Because WX = DC, therefore WX = DC = YZ = 6 cm
Because XY = BC, therefore XY = BC = WZ = 4 cm
Therefore the sides of WXYZ are
XY = 4 cm
YZ = 6 cm
WZ = 4 cm
WX = 6 cm
The perimeter of WXYZ is
4 + 6 + 4 + 6 = 20 cm
Answer: 20 cm
Answer:
x=-34
Step-by-step explanation:
isolate the variable by diving each side by the factors that don't contain a variable.
Answer:
The ratio of AC : CB is 2 : 3
Step-by-step explanation:
Calculate AC and CB using coordinates A (1, 1), B(5, 3), and C(2.6, 1.8) and the distance formula:
The probability that the first student is a girl is 5/10.
The probability of the second selection being a boy is 5/9.
(since the first selection was a girl, there are 9 students left)
The probability that the third student is a girl is 4/8
(there are 4 girls left after one was selected, and 8 students left in total, after the second selection.
The probability is (5/10)(5/9)(4/8)=0.139
Answer: 0.139
Answer:
True
Step-by-step explanation:
For a compound inequality using the word "or" to be true, all you need is for one of the parts to be true.
-6 < 7 is true
-2 <= -2 is also true
Answer: True
