60 is mirrored to 4x. meaning both are the same value

60 × 2 = 120

360 - 120 = 240

Since m and it's mirrored angle are equal value, then

240 ÷ 2 = 120

answer is 120

Answer:

120°

Step-by-step explanation:

KML and HMG are equal. So 60 + 60 = 120.

The entire angle is 360°

360 - 120 = 240

The other two angles equals 240°

To find KMH (one of the angles) do:

240/2 = 120°

What is the answer to 18 - 3w = 4w

adelina 88 [10]

Answer:

Step-by-step explanation:

$18 - 3w = 4w$

Let's get all of the terms with the $w$ on the right-hand side of the equation, and everything else on the left-hand side of the equation.

To do this, we should add $3w$ to both sides of the equation to remove the $-3w$ from the left-hand side of the equation:

$18 - 3w + 3w = 4w + 3w$

$18 = 7w$

Finally, to get the $w$ by itself, we can divide both sides by $7$ :

$\frac{18}{7} = \frac{7w}{7}$

$w = \frac{18}{7}$

The radius r(t)r(t)r, (, t, )of the base of a cylinder is increasing at a rate of 111 meter per hour and the height h(t)h(t)h, (

sp2606 [1]

Answer:

The volume is decreasing at a rate 20π cubic meter per hour.

Step-by-step explanation:

We are given the following in the question:

The radius is increasing at a rate 1 meter per hour.

$\dfrac{dr}{dt} = 1\text{ meter per hour}$

The height is decreasing at a rate 4 meter per hour

$\dfrac{dh}{dt} = -4\text{ meter per hour}$

At an instant time t,

r = 5 meter

h = 8 meters

Volume of cylinder =

$\pi r^2 h$

where r is the radius and h is the height of the cylinder.

Rate of change of volume is given by:

$\dfrac{dV}{dt} = \dfrac{d(\pi r^2 h)}{dt}\\\\\dfrac{dV}{dt} = 2\pi rh\dfrac{dr}{dt} + \pi r^2\dfrac{dh}{dt}$

Putting all the values we get,

$\dfrac{dV}{dt} = 2\pi (5)(8)(1) + \pi (5)^2(-4)\\\\\dfrac{dV}{dt} = 80\pi - 100\pi = -20\pi \approx -62.8$

Thus, the volume is decreasing at a rate 20π cubic meter per hour or 62.8 cubic meter per hour.

If the H.C.F of 210 and 55 is expressible in the form of 210*5 + 55y , find 'y' ?

Ilya [14]

Answer:

y = - 19

Step-by-step explanation:

Express 210 and 55 as products of their prime factors, that is

210 = 2 × 3 × 5 × 7

55 = 5 × 11

Identify the prime factors that both numbers have in common and multiply them.

Here only 5 is common, thus

HCF = 5

Thus

5 = 210 × 5 + 55y, that is

5 = 1050 + 55y ( subtract 1050 from both sides )

- 1045 = 55y ( divide both sides by 55 )

y = - 19
