Mathematics
1 answer:
sweet-ann [11.9K]3 years ago
5 0

Answer:

109

Step-by-step explanation:

Add 29 plus 42 to get the amount of space already being taken up to get 71 as the amount of space being taken up then subtract 180 because the space in total including x is 180 degrees so you subtract 180-71 to get 109

PLSSSS HALLPP!!! DUE TODAY!!! PLS AND THANK YOU!!

Answer:

$100.4

Step-by-step explanation:

Compound Interest Formula:

A = P(1 + \frac{r}{100})^{t}

=> A = 100 x ( 1 + \frac{0.4}{100})^1 = 100.4 (If they asked ... interest rate ... per year, if not then depends - most likely to be days and therefore you will need to change 1 year = 365 days and you will also need to change 1 in the formula above to 365, then you will get the right ans)

The Westside dog kennel is Building a circular dog park the length of the fence around the park is approximately 110 feet how mu
vredina [299]
You are basically looking to find the area of a circle 
so to find the area of a circle the formula is  A=pi R sqr
so if you take the radius which is half of the diameter 110 you get 55
you multiply 55*55 and get 3025
you than multiply that by pie and get 
9503.32 if you round

whats the equation for the perpendicular bisector of the line segment whose endpoints are (-5,3) and (3,7)?
riadik2000 [5.3K]

Answer:

The equation of perpendicular bisector of the line segment passing through  (-5,3) and (3,7) is: y = -2x+3

Step-by-step explanation:

Given points are:

(-5,3) and (3,7)

The perpendicular bisector of line segment formed by given points will pass through the mid-point of the line segment.

First of all we have to find the slope and mid-point of given line

Here

(x1,y1) = (-5,3)

(x2,y2) = (3,7)

The slope will be:

m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{7-3}{3+5}\\m = \frac{4}{8}\\m = \frac{1}{2}

The mid-point will be:

(x,y) = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\ = (\frac{-5+3}{2},\frac{3+7}{2})\\= (\frac{-2}{2},\frac{10}{2})\\=(-1,5)

Let m1 be the slope of the perpendicular bisector

Then using, "Product of slopes of perpendicular lines is -1"

m.m_1 = -1\\\frac{1}{2}.m_1 = -1\\m_1 = -1*2\\m_1 = -2

We have to find the equation of a line with slope -2 and passing through (-1,5)

The slope-intercept form is given by:

y = mx+b\\y = -2x+b

Putting the point (-1,5) in the equation

5 = -2(-1)+b\\5 = 2+b\\b = 5-2\\b = 3

The final equation is:

y = -2x+3

Hence,

The equation of perpendicular bisector of the line segment passing through  (-5,3) and (3,7) is: y = -2x+3

The sum of the interior angles of a polygon with n sides is 1980°. Find n.
natka813 [3]

Answer:

n = 13

Step-by-step explanation:

The sum of the measures of the interior angles of an n-sided polygon is

(n - 2)180

Set (n - 2)180 equal to 1980 and solve for n.

(n - 2)180 = 1980

Divide both sides by 180.

n - 2 = 11

Add 2 to both sides.

n = 13
