Answer: 4m - 6
Step-by-step explanation:
------------------------------------------------------------------
Given Information
------------------------------------------------------------------
Square Area = 156.25m²
------------------------------------------------------------------
Formula
------------------------------------------------------------------
Area = Length x Length
------------------------------------------------------------------
Find Length
------------------------------------------------------------------
156.25 = Length x Length
156.25 = Length²
Length² = 156.25
Length = √156.25
Length = 12.5
------------------------------------------------------------------
Formula
------------------------------------------------------------------
a² + b² = c²
------------------------------------------------------------------
Find Diagonal
------------------------------------------------------------------
12.5² + 12.5² = c²
c² = 156.25 + 156.25
c² = 312.5
c = √312.5
c = 17.68m (nearest hundredth)
------------------------------------------------------------------
Answer: The diagonal length is 17.68m
------------------------------------------------------------------
Answer:
<u>The correct answer is B. 9</u>
Step-by-step explanation:
Let's solve for y in the equation below, given that x = 2
y = 6x - 3
Substituting x in the equation, this way:
y = 6 * 2 - 3
y = 12 - 3
y = 9
The value of y is 9 when x is 2
<u>The correct answer is B. 9</u>
Answer:
The correct answer is last option
10
Step-by-step explanation:
Points to remember
<u>Distance formula</u>
Length of a line segment with end points (x1, y1) and (x2, y2) is given by,
Distance = √[(x2 - x1)² + (y2 - y1)²]
<u>To find the distance between given points</u>
Here (x1, y1) = R(0, 0) and (x2, y2) = S(6, 8)
Distance, RS = √[(x2 - x1)² + (y2 - y1)²]
= √[(6 - 0)² + (8 - 0)²]
= √[6² + 8²]
= √[36 + 64]
= √100
= 10
Therefore the correct answer is last option 10
