Multiplying both sides of an equation by the same number keeps the equation true. In this example, both sides are multiplied by 3, so the equation isn't changed.
Answer:
Step-by-step explanation:
height of triangle=√(11²-8.6²)=√(11+8.6)(11-8.6)=√(19.6×2.4)
=√(4×4.9×4×0.6)=4√(4.9×0.6)=4√2.94
area of triangle=1/2 bh=1/2×2×8.6×4√2.94
=34.4×√2.94
≈58.984
Answer:
1 3/40
Step-by-step explanation:
1 1/4 +1 1/5 +7/8= 3 13/40
3/4 .3= 2 1/4
3 13/40 - 2 1/4
Multiplicative inverse is a number which when multiplied with the current number, the answer unit (that is, 1).
Now,
1.725 = 1725/1000 = 69/40
Inverting this and multiplying it with the results yields 1. That is,
69/40*40/69 = 1
Therefore, the multiplicative inverse of 1.725 is 40/69
