-4+x=9.5
x=13.5

The student might have subtracted 9.5-4, which results in the answer 5.5. The correct answer is 13.5.

What equation describes the circle that is centered at (8, 3) and has a radius of 9

Sloan [31]

Answer:

Step-by-step explanation:

The general equation of a circle is expressed as;

(x-a)²+(y-b)² = r² where;

(a, b) is the centre of the circle

r is the radius

Given the centre (8, 3) and the radius of 9, the equation of the circle will be;

(x-a)²+(y-b)² = r²

(x-8)²+(y-3)² = 9²

(x-8)²+(y-3)² = 81

hence the required equation is (x-8)²+(y-3)² = 81

Paul bags of raisin bars in a pan shaped like a rectangle or prism the volume of the pan is 252 in.³ the length of the pants 12

e-lub [12.9K]

Answer:

The height of the pan is 2 inches.

Step-by-step explanation:

Given : Paul bags of raisin bars in a pan shaped like a rectangle or prism the volume of the pan is 252 in.³ the length of the pants 12 inches and it's with is $10\frac{1}{2}$ inches.

To find : What is the height of the pan ?

Solution :

The volume of a rectangle or prism is

$V=l\times w\times h$

Where, l=12 inches is the length

$w=10\frac{1}{2}$ inches is the width

V=252 in.³ is the volume

h is the height

Substitute the value,

$252=12\times 10\frac{1}{2}\times h$

$252=12\times \frac{21}{2}\times h$

$h=\frac{252\times 2}{12\times 21}$

$h=2$

Therefore, the height of the pan is 2 inches.
