Answer:
a) 10 percent of 800,000 is 80,000
80,000*3=240,000
They will allow a discount of 240,000, making the price 560,000.
b) 10 percent of 1,000,000 is 100,000
100,000*3=300,000
They will allow a discount of 300,000, making the price, 700,000.
Answer:
d = 17.5499287748 inches or 17.5 inches to 1 decimal place
Step-by-step explanation:
find the diagonal line passing through the middle of the bottom rectangle:
a² + b² = c²
10² + 8² = c²
100 + 64 = 164
c² = 164
c = √164
c = 12.8062484729
find d:
a² + b² = c²
12² + 12.80624847298² = c²
144+ 164 = 308
c² = 308
c = √308
c = 17.5499287748
therefore d = 17.5499287748 inches or 17.5 inches to 1 decimal place
