The suppliment of angle k is three times the measure of angle k. what is the measure of angle k

1 answer:

8 0

An angle - k, its supplement angle is 3k.
Because these angles are supplement , we can write
k+3k=180
4k=180
k=180/4
k=45

Using the formula for volume of a cone, express r in terms of V, h and pi

DiKsa [7]

The volume of the cone is one-third of the volume of the cylinder which is equal to the product of area of the base and the height. The equation is,

V = (1/3)(pi)(r^2)h

Dividing both sides of the equation by (1/3)(pi)(h) will give us,

3V/(pi)(h) = r^2

Taking the square-root of both sides,

r = sqrt(3V/(pi)(h))

Ab and bc form a right angle at point B. if a= (-3,-1) and B= (4,4) what is the equation of BC?

Vesnalui [34]

Answer:

Option C $-7x-5y=-48$

Step-by-step explanation:

step 1

Find the slope of AB

we have

A(-3,-1) and B(4,4)

The slope m is equal to

$m=(4+1)/(4+3)$

$m=5/7$

step 2

Find the slope of BC

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

$m1*m2=-1$

we have

$m1=5/7$

substitute

$5/7*m2=-1$

$m2=-7/5$

step 3

Find the equation of the line into slope point form

$y-y1=m(x-x1)$

we have

$m=-7/5$

$B(4,4)$

substitute

$y-4=-(7/5)(x-4)$

Multiply by 5 both sides

$5y-20=-7x+28$

$7x+5y=28+20$

$7x+5y=48$

Multiply by -1 both sides

$-7x-5y=-48$

One taxi leaves at a stop at every 6 minutes a second taxi leaves the stop every 9 minutes if they leave at 4.00 p.m at what tim

qaws [65]

Both taxis will leave together at 04:18 PM after 04:00 PM

Step-by-step explanation:

We have to use the LCM to find the time on which both will leave at the same time,

Given

Departure interval for first taxi = 6 minutes

Departure interval for second taxi = 9 minutes

We have to find the LCM of 9 and 6

So,

Factors of 6: 6,12,18,24,30,36,42,48,54,60

Factors of 9: 9,18,27,36,45,54,63,72

The LCM is 18.

So,

Both taxis will leave together at 04:18 PM after 04:00 PM
