46 iris blooms
Let 40 be 100% - value of iris blooms last year
Add 15% to 100% - the increase of iris blooms this year
Multiply 40 by 115% = 46
Multiply 40 by 15% = 6
Add 6 to 40 = 46
15% increase means 100%+15% = 115% = 1.15
so 40 * 1.15 = 46
i think your teacher also means to derive that formula where t on one side. here are steps to do that:
multiply both side by 2, to cancel out 1/2
now to cancel g, divide both side of the equation by g
now t is . but we're not done yet. we have to remove the exponent two by radical or square root.
now solve the problem with that formula
h = 3.5m
g = 9.81m/s
substitute from our formula.
and the answer is
step-by-step explanation: coplanar circles that intersect in one point are called tangent circles. coplanar circles that have a common center are called concentric.
