Answer:
80%
Step-by-step explanation:
The percentage change is calculated from ...
percent change = ((new)/(old) -1) × 100%
= (72/40 -1) × 100%
= (1.8 -1) × 100%
= 80%
The second value is 80% greater than the first.
Multiply the variable k times 4 would give you 4k.
Then cross multiply 14x8 = 112
Therefore, you would have 4k = 112.
Divide 112 by 4 to get your answer!
Answer:
P = 2L + 2W
35 cm = 2(5 cm) + 2(W cm)
W = 12.5 cm
Step-by-step explanation:
P = 2L + 2W
35 cm = 2(5 cm) + 2(W cm)
35 cm - 10 cm = 2W cm
2W cm = 25 cm
w cm = 12.5 cm
The correct answer is 73. You can find this quite simply by subtracting 62 and 45 from 180, because all triangles angles always add up to 180.
