★ What percent of 176 is 156?

To find the percent, first divide the part over the whole.

\frac{Number}{Total} = \frac{156}{176}

Divide

156 \div 176 = 0.886

You have your answer as a decimal. All you need to do is convert it into a percent.

★ To convert a decimal to a percent, move the decimal point two places to the right and add a percent sign.

0.886 \rightarrow 88.6 \%

ANSWER: A)88.6%

F(x)=1/2x+4 For R={5,6,7,8}
anzhelika [568]

Hey there!!

Remember : R = range and f ( x ) = y and y = range

R : { 5 , 6 , 7 , 8 }

( 1 ) 5 = 1 x / 2 + 4

... 5 - 4 = x / 2

... 1 = x / 2

... x = 2 = ( 2 , 5 )

( 2 ) 6 = x / 2 + 4

... 2 = x / 2

... x = 4 = ( 4 , 6 )

( 3 ) 7 = x / 2 + 4

... 3 = x / 2

... x = 6 = ( 6 , 7 )

( 4 ) 8 = x /2 + 4

... 4 = x/2

... x = 8 = ( 8 , 8 )

Hope my answer helps!

(255)/(6)*(672)/(9)+(37)/(9) <br> How do you work this out step by step??
koban [17]
Step 1. Type it into a Google search box or calculator. (You need to use a calculator anyway.) The result is 3177 4/9.

If you're doing this according to the Order of Operations, you do the multiplication and division left to right. This means the first calculation you do is
  255/6 = 42.5
Next, you multiply by 672
  42.5*672 = 28560
Then divide by 9
  28560/9 = 3173 3/9

You continue by doing the division
  37/9 = 4 1/9

And finish by adding the two results
  3173 3/9 + 4 1/9 = 3174 4/9

_____
If you're doing this by hand, you can recognize the first term as the product of two fractions, so is the product of numerators divided by the product of denominators.
  (255*672)/(6*9)
Using your knowledge of divisibility rules, you can do the division 672/6 to simplify this to
  (255*112)/9
Now, the first term and the second term have the same denominator, so you can add the numerators before you do the division.
  (255*112 + 37)/9 = (28560 + 37)/9 = 28597/9
You end up having to do only two simple divisions, rather than 3 of them.
  28597/9 = 3177 4/9

The circle below has center P, and its radius is 3 m. Given that m 2 QPR=170°, find the length of the minor arc OR.
QveST [7]

Any smooth curve connecting two points is called an arc. The length of the arc m∠QPR is 2.8334π m.

<h3>What is the Length of an Arc?</h3>

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}

where

θ is the angle, that which arc creates at the centre of the circle in degree.

Given the radius of the circle is 3m, while the angle made by the arc at the centre of the circle is 170°. Therefore,

The length of an arc = 2πr×(θ/360°) = 2π × 3 ×(170/360°) = 2.8334π m

Hence, the length of the arc m∠QPR is 2.8334π m.

how many minutes is it before 12 noon if 20 minutes ago it was three times as many minutes after 9 am
Hunter-Best [27]
First, change everything into minutes.
12 noon is 12 by 60 which = 720 minutes.
9am is 9 by 12 which = 540 minutes.
X is now your number of minutes before noon.So noon - x is the next step:
720 - x
20 minutes ago it was 720 - x - 20
720 - x - 20= 540 + 3x (3x because you're looking for 3 times as many minutes)
720 - 20 - 540=4x (you combine all the like numbers and variables) 
160 = 4x
160/4= x
40 = x
Your answer is 40 minutes

Find x when<br> k(x) = -6<br> k(x) = -7x+1
sp2606 [1]

Answer:

x = 1

Step-by-step explanation:

Since both equations are equal to k(x), both equations are also equal to each other.

Begin by setting up the equation like this: -6 = -7x + 1

Simply solve for x by subtracting each side by 1 (-7 = -7x)

Finally, divide both sides by -7 to get 1.
