The circumference of a circle is 2\pi r and it coresponds to a 360 degree angle.

The circumference of the circle is 2*4*pi=8pi m=25.12m

25.12m......360 degrees
10 m.........x degrees
x=10*360/25.12=143.31 degrees

The quantity r varies jointly with t and u and inversely with s when t= -12, u= -7, and s= -4, r= -126. Find r when t= -8, u= 8,
vichka [17]

Answer:

r = 64

Step-by-step explanation:

r = (k*t*u)/s

Where,

k = constant of proportionality

t = -12,

u= -7,

s= -4,

r= -126.

r = (k*t*u)/s

-126 = (k*-12*-7)/-4

-126 * -4 = 84k

504 = 84k

k = 504/84

k = 6

Find r when t= -8, u= 8, and s= -6.

r = (k*t*u)/s

= (6*-8*8) / -6

= -384 / -6

= 64

r = 64

the angles of a triangle are in the ratio 3:4:5. what is the degree measure of the smallest angle of the triangle?
Alik [6]
A triangle interior angles add up to 180

so we have 3:4:5
the ratio of the angles
 3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees

Convert the following in standard form : -4x=4y-52
goldenfox [79]
The standard form of any linear equation with two variables is ax+by=c, where a, b, and c are constants. To convert this equation to standard form, simply subtract 4y from both sides to get

-4x-4y=-52

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get

4x+4y=52
