Answer:

10 Inches

Hope it helps, have a fantastic day.

Step-by-step explanation:

The Circumference of a circle can be displayed by this formula:

C = 2\pi r

C is the circumference, and r is the radius.

So just plug in 31 for C, and simplify:

31 = 2\pi r

Because the question is asking for the diameter, we only need to divide both sides by pi, as 2r is the same thing as diameter.

9.87 = 2r (rounded to the nearest hundredth)

We can even rewrite 2r as d, which stands for diameter, to make things a little simpler.

9.87 = d

Now we just take 9.87, and round it to the nearest whole number, and we get 10. So your answer is 10 Inches.

Hope it helps, have a fantastic day.

Make a conjecture: How many solutions does a quartic equation x 4 + ax 3 + bx 2 + cx + d = 0 have? Explain.
Ratling [72]

Answer:

Four

Step-by-step explanation:

The degree of a polynomial is the highest of the degree of the monomials with non-zero co-efficient. In this problem we are given the polynomial:

                 $ x^4 + ax^3 + bx^2 + cx + d = 0 $

The degree of the polynomial is 4.

For a polynomial of <em>n- degree </em>we have <em>n solutions counting multiplicity</em>.

So for this four degree polynomial we would have 4 solutions. Could be real or complex depending on the equation.

Jack has a mask collection of 500 masks. He keeps 235 of the masks on his wall. What percentage of Jack's mask collection does h
marta [7]

Answer:

47%

Step-by-step explanation:

First we need to find the ratio of masks on Jack's wall to the total number of masks, which is 235/500. Now we need to make the denominator 100 in order to find the percentage by dividing the numerator and denominator by 5 to get 47/100. Therefore the percentage of Jack's mask collection that is on his wall is 47%.

Vertical and horizontal line (1,-4)—do X=blank and Y=blank
Mila [183]

Answer:

x = 1 and y = - 4

Step-by-step explanation:

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line goes through.

Here the line passes through (1, - 4) with x- coordinate 1, thus

x = 1 ← equation of vertical line

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line goes through.

Here the line passes through (1, - 4) with y- coordinate - 4, thus

y = - 4 ← equation of horizontal line
