Mathematics
1 answer:
guapka [62]3 years ago
6 0

Answer:

Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715

Put 3x+12y=-96 into slope intercept form
RideAnS [48]

Answer:

y =-1/4x -8

Step-by-step explanation:

3x+12y=-96

Slope intercept form is y = mx +b where m is the slope and b is the y intercept

Subtract 3x from each side

3x -3x+12y=-3x-96

12y = -3x-96

Divide each side by 12

12y/12 = -3x/12 -96/12

y =-1/4x -8

Suppose y varies directly as X, and Y equals 16 when x equals 8 find y when x equal 16
Korolek [52]
When
y = x \\ y = 16 \\ x = 8
you would have to use comon multiples to find what both numbers have in common, a short way of finding this would be
16 \div 8 = a
where (a) is the answer of the equation, (a) would be 2 because 8*2=16 meaning
y = 2x

Instructions: Find the following information using the given image.
igor_vitrenko [27]

Answer:

Segment 1: 16

Segment 2: 9

x=12

Step-by-step explanation:

25=16+ segment 2

Subtract 25-16 and you get 9 and that is your Segment 2

Now, cross multiply

\frac{9}{x} * \frac{x}{16}

9*16=144

Now simplify it.

144/12

And there is your x=12

I can confirm this is right because I just turned it in and it came out correct.

4) Expression: 360<br> What is the value?
myrzilka [38]

The value of \sqrt{360} is 18.974.

Solution:

Given expression:

\sqrt{360}

To simplify the given expression and find the value.

\sqrt{360}

Factor the value 360 = 36 × 10.

\sqrt{360}=\sqrt{36\times 10}

36 can be written as 6 × 6 = 6²

10 can be written as 2 × 5.

       =\sqrt{6^2\times 2\times 5}

      =6\sqrt{2\times 5}

      =6\sqrt{10}

      = 18.974

The value of \sqrt{360} is 18.974.
