Answer:
Option C. 15 cm
Step-by-step explanation:
The correct question is
A triangle has two sides that measure 8.7 cm and 12.3 cm. Which could be the measure of the third side?
A. 2.6 cm
B. 3.6 cm
C. 15 cm
D. 21 cm
we know that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
Analyze two cases
Let
x ----> the length of the third side
First case
x+8.7 > 12.3
x>12.3-8.7
x> 3.6 cm
Second case
12.3+8.7 > x
21 > x
Rewrite
x < 21 cm
Answer: 5
This is because (4r + 6) means you take r and multiply that number by 4.
Because there is no number, r would equal one in this case.
4 • 1 is 4
4 + 6 is 10
This would give us 1/2(10)
Half of 10 is 5.
Therefore, the answer is 5.
Answer:
kitchen
Step-by-step explanation:
if a foot is 2.389 then i would be pretty far but not a block away
After 1 year it is worth 108% of its original value
108% = 1.08
so 1.08 x 1000 = $1080
After 2nd year it is worth 92% of that $1080
92% = 0.92
so 0.92 x 1080 = $993.60
Answer:
total cost= $5,814
Step-by-step explanation:
Total linear feet measured: (110 x 2) + (270 x 2) = 760 linear ft
total sq ft= 760 x (7) = 5320 sq ft
total linear ft x labor= 760 x 1.70 = 1292 labor
Total sq ft x Cyclone fencing cost= 5320 x .85 = 4522
the total cost is 1292 + 4522 = $5,814
