12x2= $24
24+28+45= $97
So $97 is 100%
So 100%-30% =70% (30% off)
(note: 70% = 70/100 = 0.7)
97 x 0.7 = $67.90
Answer:
The answer is 180
Step-by-step explanation:
So to start off you have to turn 20% into a decimal and that is .20.
Next you need to mutiply 225 and .20 and you will get 45 (that means it is $45 off)
Subtract 45 fro 225 and that is your answer.
You now pay $180 for the 20 foot extension ladder.
Answer:
The answer to your question is: B and D are correct
Step-by-step explanation:
Remember that the sum of the internal angles in a triangle equals 180°.
The sum of supplementary angles equals 180°
Then
(6x + 1) + (4x + 5) + [180 - (8x + 30)] = 180
6x + 1 + 4x + 5 + [180 - 8x - 30] = 180
10x + 6 + 150 - 8x = 180
2 x = 180 - 156
2x = 24
x = 24/2
x = 12
∠JKL = 4(12) + 5 = 48 + 5 = 53
∠KJL = 6(12) + 1 = 72 + 1 = 73
∠KLJ = 180 - 73 - 53 = 54
∠KLM = 126
Step-by-step explanation:
Given,
Side of a square = 4xy
Therefore, area of the square = side × side
= 4xy × 4xy
