Answer:

1 5/12

Step-by-step explanation:

12 1/3 - 10 11/12

We need to get a common denominator of 12

12 1/3 * 4/4 - 10 11/12

12 4/12 - 10 11/12

We need to borrow from the 12 (the whole number) because the 2nd fraction is bigger than the first

12 becomes 11 and the 1 becomes 12/12

11+ (12/12 + 4/12) - 10 11/12

11 16/12 - 10 11/12

Subtract the whole numbers

11-10 =1

Subtract the fractions

16/12 - 11 /12 = 5 /12

We are left with 1 5/12

What is the order of rotational symmetry for a rhombus?

Westkost [7]

A rhombus has rotational symmetry. It is a symmetric shape that can be rotated and still appear the same. A rhombus has two-fold symmetry, meaning that is can be rotated 180 degrees and appear the same.

I love simple math.

3.25$ to wash the car.

60 seconds: 1 quarter

how many quarters is 3.25?

4 quarters per dollar. so it'd be 13 quarters, then do 13*60=how many seconds u got. 780 seconds. I think you can do 780/60

The center of a circle and a point on the circle are given. Write the equation of the circle in standard form.

nirvana33 [79]

$(x-2)^2+(y+2)^2=34$

Step-by-step explanation:

Write the equation of the circle in standard form, where center: (2,-2), point on the circle: (5,3)

The equation of circle in standard form is:

$r^2=(x-h)^2+(y-k)^2$

Where (h,k) is center and r is the radius.

We are given center (2,-2) and we need to find radius r

We know a point on circle (5,3) and center (2,-2)

Finding distance between these points:

$r = d= \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2} \\r= d=\sqrt{(5-2)^2+(3-(-2))^2}\\r= d=\sqrt{(3)^2+(5)^2}\\r= d=\sqrt{9+25}\\r= d=\sqrt{34}$

So, r = √34

then r^2 = 34

So, equation of circle is:

$(x-h)^2+(y-k)^2=r^2\\(x-2)^2+(y-(-2))^2=34\\(x-2)^2+(y+2)^2=34$
