The minute hand of a clock is 7 in. Long how far does the point of the hand travel in 60 minutes?

Mathematics

Semmy [17]3 years ago

Answer:

Step-by-step explanation:

60 minutes is one hour, which is all the way around the outside of the clock one time.  This distance is represented by the circumference of a circle, assuming that the clock is in fact circular.  The formula for the circumference of a circle in terms of the radius is

C=2\pi r

Our radius is 7, so the distance around the outside of that particular clock (and how far the minute hand travels if it goes around the clock one time) is

C=2\pi (7) or

C = 14π

If you want the decimal equivalency for that, multiply in pi as 3.1415 and round to whatever place you need.  In decimal form, that is

C = 43.9 inches

10.03 is what percent of 29.5
Maru [420]
Percent formula : is/of = %/100

is = 10.03
of = 29.5
percent = x

now we sub
10.03/29.5 = x/100
this is a proportion, so we must cross multiply
(29.5)(x) = (10.03)(100)
29.5x = 1003
x = 1003/29.5
x = 34 <==== 10.03 is 34% of 29.5

Rewrite the polynomial-9x^5+36x^4+189x^3 in factored form, using the factoring method method you prefer.
ozzi

The polynomial 9x^5+36x^4+189x^3 in factored form is -9 x \times x \times x \times(x-7) \times(x+3)

<u>Solution:</u>

Given, polynomial equation is -9 x^{5}+36 x^{4}+189 x^{3}

We have to find the factored form of the above given polynomial equation.

Let us solve it by grouping.

Now, take the polynomial ⇒ -9 x^{5}+36 x^{4}+189 x^{3}

By taking common term out, we get

\rightarrow-9 x^{3}\left(x^{2}-4 x-21\right)

\rightarrow-9 x^{3}\left(x^{2}-(7-3) x-7 \times 3\right)

Grouping the terms we get,

\rightarrow-9 x^{3}\left(\left(x^{2}-7 x\right)+(3 x-7 x^3)\right)

Taking common terms out from each group,

\rightarrow-9 x^{3}(x(x-7)+3(x-7))

\Rightarrow-9 x^{3}((x-7)(x+3))

\rightarrow-9 x \times x \times x \times(x-7) \times(x+3)

Thus the factored form of polynomial is found out

Multiplying Integers
kolezko [41]

Answer:

Multiplying Integers

1) (-4)(-12) = 48

2) -8 X (-8) = 64

3) (-8)(-10) = 89

4) 5 x 1 = 5

5) (-10)(11) = -110

6) (-3)(-8) = 24

9) 4 x (-10) = -40

7) -2 x 6 = -12

8) 7(-12) = -84

10) (-9)(-6)(2) = 108

11) (-10)(-7)(-4) = -280
