A ratio is like a fraction, so since you are provided with the numbers its easy to put it into a ratio
depth is 3.8km
width is 7600km
ratio is 3.8:7600
The coefficient of y∧15×∧2 in expansion of (y∧3+x)∧7 is (15×2)+(3×7)= 51
Answer:
x^2 = 10^2 - 9^2
x^2 = 100 -81 = 19
x = 4.3588989435
The triangle sides are 10, 9 and 4.3588989435
Step-by-step explanation:
Answer: £5000
Step-by-step explanation:
If 12% decrease = £600
Then (100- 12)% = x
100% = x
0.12x = 600 x 0.88
0.12x = 528
Divide both sides by 0.12
£4400
Therefore, original price before 12% decrease was £5000
