Answer:
largest weight = 27.65 kg, lowest weight = 3.95 kg
Step-by-step explanation:
7:1 --> 7 + 1 = total of both ratio is 8
8 --> 31.6kg
1 --> 3.95 kg
so 7 --> 3.95 * 7 = 27.65 kg
so 1 --> 3.95 * 1 = 3.95 kg
A quadratic equation has the general formula
expressed as:<span>
ax^2 + bx - c = 0
This equation can be solved by the quadratic
formula which is expressed as:
x = ( -b (+ or -) √(b^2 - 4ac) / 2a
From the given equation, </span><span> y=-0.005x^2+0.41x-5.1
</span><span>
a = -0.005
b = 0.41
c = -5.1
Using the quadratic formula and the corresponding values of the coefficient, we substitute these and obtain:
</span>x = ( -b (+ or -) √(b^2 - 4ac) / 2a
x = ( -0.41 (+ or -) √(0.41^2 - 4(-0.005)(5.1)) / 2(-0.005)
x1 =66.71
x2 = 15.29
Therefore, the quadratic equation would be factored by using the values of x we obtained as follows:
<span>y= -0.005x^2 + 0.41x - 5.1
</span>y = (x - 66.71) ( x - 15.29 )
7.4 kg = 74hg = 740dag = 7400g = 74,000 dg = 740,000 cg = 7,400,000 mg

Now which equivalent were you looking for?
Answer:
0.9 , 0.088 , 0.032
Step-by-step explanation:
0.9 --> 1st greatest
0.088 --> 2nd greatest
0.032 --> 3rd greatest
So, 0.9 , 0.088 , 0.032
