Answer:
3 pounds
u have to use y=mx+b
90=7.68x+66.96
subtract the 66.96 from the 90
then just divide
Answer:
Height = 25.46 inches
Width = 50.92 inches
Step-by-step explanation:
We can say area of a triangle is :
Area = 1/2 * length * height
The banner is twice as long and height, we can say:
length = 2*height
Since, area given as 648, we can write:
Height = 25.46 inches
Width = 2 * 25.46 = 50.92 inches
The Answer:
21 - 9 = 12, not 11.
explanation:
It is not much else to say here, so straightforward, the answer lies above.
Therefore,
you are correct. 11 + 9 = 20 - 9 = 11, which is correct for the given equation.
Answer:
100
Step-by-step explanation:
cosB = 36/60 = 3/5
cosB = 60/x = 3/5 -> x = 100
We are given original equation:
We need to find the enter and radius of a circle using the completing the square method.
The steps are as following :
Step 1 [original equation]: x^2 − 10x + y^2 + 12y = 20 .
Step 2 [group like terms]: (x^2 − 10x) + (y^2 + 12y) = 20
Step 3 [complete the quadratics]: (x^2 − 10x + 25) + (y^2 + 12y + 36) = 20 + (25 + 36).
Step 4 [simplify the equation]: (x^2 − 10x + 25) + (y^2 + 12y + 36) = 64.
Step 5 [factor each quadratic]: (x − 5)^2 + (y + 6)^2 = 8^2
Step 6 [identify the center and radius]: Center = (5, −6) Radius = 8.
<h3>Step 6 is incorrect.</h3><h3>The center should be (5,-6).</h3><h3> Replace − 5 with + 5 and replace + 6 with − 6.</h3>
