Solve v=1/3 bh for b

katovenus [111]

Answer:

3v/h = b

Step-by-step explanation:

1/3 is a given fraction and to get rid of it you must multiply by it's reciprocal of 3/1 or 3. You will also multiply the other side by 3

3 * v = (1/3 bh) * 3 --> 3v = bh

divde both sides by h and you get 3v over h = b

3v/h = b

Hope this helps!

Write the standard form of the equation of the circle described below.

Luden [163]

Equation of circle is $x^2+(y+2)^2=26$

Step-by-step explanation:

The standard form of the equation of circle is:

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

where (h,k) is the center of the circle and r is the radius of circle.

We need to find the radius of circle r by using distance formula:

$r=d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}\\r=d=\sqrt{(-5-0)^2+(-1-(-2))^2}\\r=d=\sqrt{(-5)^2+(1)^2}\\r=d=\sqrt{25+1}\\r=d=\sqrt{26}$

r=√26

and r^2= 26

Putting values of r^2=26 and value of center (h,k)=(0,-2)

the equation of Circle is:

$(x-h)^2+(y-k)^2=r^2\\(x-0)^2+(y-(-2)^2=26\\x^2+(y+2)^2=26$

The figure shows a grapefruit half. The radius to the outsideof the rind is 5 cm. The radius to the inside of the rind is 4 cm.T

Marysya12 [62]

Answer:

the volume of the inside of half grapefruit is ( 128/3) pi the volume of 1 of the 12 segments is (32/9) pi

Step-by-step explanation:

The volume of half a sphere (hemisphere) is (2/3) pi r^3

(2/3) 4^3 pi = (2/3)(64)pi = (128/3) pi -

The volume of one of the 12 segements is the answer divided by 12

128/36 pi =( (32/9) pi

I need help I failing

Liono4ka [1.6K]

Answer:

A and C

Step-by-step explanation:

Both A and C are the same shape, same size, but C is flipped over. If you were to cut out the two shapes and put them over one another, they would be the same. You can also count the blocks that are in the shape itself to see if they match.

The longer side on both has 2.5 blocks in it, the side is two blocks tall, and the smaller line has 1.5 of the block shown.

I'll will implement a sketch to show you what I mean and submit it here. Look at it if you are still confused

I hope this helps!
