Use long division to convert − 21 60 to a decimal. a) 0.45 b) 0.27 c) −0.35 d) −0.33

C is correct.

Step-by-step explanation:

Use long division to convert − 21/60 to a decimal.

We are given a fraction and need to write as decimal form.

It is negative fraction. When we change into decimal sign of number doesn't change.

As we can see numerator is smaller than denominator.

So, First we will take decimal and mark 0 at numerator.

Please see the attachment for long division:

60 )  210     ( 0.35

     -  180

           300

        -  300

              0

We get remainder as 0

When we divide 21/60 quotient is 0.35 and remainder is 0.

Hence, The given fraction equivalent to -0.35 in decimal.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
