Step-by-step explanation:
1. "<span>The corresponding sides of (triangles) abc and def have equal lengths.</span>" means that the triangles are congruent, that is exactly identical, by the Side Side Side (SSS) postulate.
2. 2 congruent triangle, have equal area
3. A(DEF)=A(ABC)=4 square units
Answer: 4 units squared
Answer:
Distinct ways in which they all can form the teams for the class = n(n-1)
Step-by-step explanation:
Total numbers of students = n (even number)
Number of student in each team = 2
Number of distinct ways are there to form the teams for the class:
where = n = number of elements = n
k = number of elements choose = 2
The correct answer is 9.64 square units
Explanation:
The area of a rectangular pool can be calculated simply by multiplying the length by the width. Moreover, this formula A = L × W can also be used to find any of the values if the two other values are known. For example, in this mathematical problem, the length and area are provided. The process to calculate the area is shown below:
A = L × W or A = L × W
12.5 × y (unknown value) = 120. 5 (area)
Move 12.5 to the other side of the equation and divide 120.5 into 12.5 as once you move a value to the other side of an equation the inverse operation should be used (12.5 multiplies y but if it is moved to the other side it needs to divide)
y = 120.5 ÷ 12.5
y = 9.64 square units
The width of the pool is 9.64 units, you can also prove this because 12.5 square units × 9.64 square units = 120.5 square units.
