The base would be 13.6 cm long, if you divide the area by the height you will get the base.

Answer: 13.6

Step-by-step explanation:

First you do 216.24 divided by 15.9 (Because dividing is just multiplication backwards), then you get 13.6

Answer:

Step-by-step explanation:

We will use the tangent function since we know the opposite and adjacent sides.

Tangent = opposite/adjacent

Tan(e) = 16/10

Tan(e) = 1.6

Use the inverse tangent function to find the angle.

Arctan (1.6) = 57.9946168

Rounding this we get: 58°

The diameter of a circle has length 12. The center is at*(-5, 2). Give the equation

labwork [276]

Answer:

Equation of the circle is : $x^{2} + 10x + y^{2} -4y -7 =0$

Step-by-step explanation:

Let us consider the image attached in the answer area.

The center O has the co-ordinates i.e. (-5,2) and the diameter given is 12 units.

We know that radius is half of diameter.

$\text{Radius = }\dfrac{\text{Diameter}}{2}$

$\text{Radius = }\dfrac{12}{2}\\\Rightarrow \text{Radius = 6units}$

The equation for circle given the center and radius, can be represented as:

$(x-a)^{2}+ (y-b)^{2} = r^{2}$

Where (a,b) is the co-ordinate of center and r is the radius.

Let us consider the following formula:

$(p+q)^2 = p^{2}+ q^{2} +2pq\\(p-q)^2 = p^{2}+ q^{2} -2pq$

$(x-(-5))^{2}+ (y-2)^{2} = 6^{2}\\\Rightarrow (x+5)^{2}+ (y-2)^{2} = 36\\\Rightarrow x^{2} + 25 + 10x +y^{2} + 4-4y=36\\\Rightarrow x^{2} + 10x +y^{2} -4y-7=0$

Hence, Equation of the circle is : $x^{2} + 10x + y^{2} -4y -7 =0$

Please help please please please!!!!!

Nana76 [90]

Step-by-step explanation:

mean of cheese = 99+8+10/3 = 117/3 = 39

mean of butter = 41+16+0/3 = 57/3 = 19

mean of non fat dairy milk = 255+8+15/3 = 278/3 = 92.6~93

median of cheese 8, 10, 99 median is 10

median of butter 0, 16, 41 median is 16

nonfat dairy milk 8, 15, 255 median is 15

range of cheese 99-10 = 88

range of butter 41-16 = 25

range of nonfat dairy milk = 255-8 = 247
