16.6 is a rational number
The diagonals of a rectangle are congruent and bisect each other.
MW = HW = (1/2)(MT)
MW = HW = (1/2)(50)
MW = HW = 25
3x + y = 25
7x - 6y = 25
Multiply the first equation by 6.
Write the second equation below it.
Add the equations.
18x + 6y = 150
+ 7x - 6y = 25
--------------------------
25x = 175
x = 7
3x + y = 25
3(7) + y = 25
21 + y = 25
y = 4
Answer: x = 7; y = 4
Th area of a right triangle is A = 1/2 (ab), where a and b are the legs of the right angle. So area of the base is, A = 1/2 (9 x 12) = 108 cm2. With 2 bases, total area of base is 108 times 2, which is equal to 216 cm2. The other side of the triangular base nypotenuse) can be computed by Phythagorean theorem. Hypotenuse = square root of sum of the suare of 9 and 12. This is equal to 15 cm. There are other 3 rectangular faces with the following dimensions: 9 by 10 cm, 12 by 10 cm and 15 by 10 cm. Area of the other faces are 90, 120 and 150 cm2, by multiplying the length and width, only. Total area is 576 cm2.
Answer:
24
Step-by-step explanation:
Arrange the terms in ascending order.
20, 22, 23, 24, 24, 25, 46
The median is the middle term in the arranged data set.
