The value of x from the given figure is 8

<h3>How to calculate the interior angle of a triangle</h3>

A triangle is a 2-dimensional shape with 3 sides an interior angle

Since the sum of the interior angles of a triangle is 180 degrees, hence;

8x - 4 + 76 + 44 = 180

8x + 116 = 180

8x = 180 - 116

8x = 64

x = 64/8

x = 8

Hence the value of x from the given figure is 8

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 63 N acts on

Luba_88 [7]

Answer:

18 N

Step-by-step explanation:

Let <em>F</em> denote the force, <em>m</em> denote the mass of the object and <em>a </em>denote the acceleration of the object.

$m = \frac{F_{1} }{a_{1} }=\frac{63}{7} =9 kg$

$F_{2} =ma_{2}=9*2=18N$

Two sides of a right triangle have lengths of 4 centimeters and 7 centimeters. The third side is NOT the hypotenuse. How long is

andrezito [222]

Answer:

The third side is 5.7 centimeters.

Step-by-step explanation:

The hypothenuse is the largest side of a right triangle. So in this question, we know that the hypothenuse is 7.

One of the sides is 4, and the other is x.

Applying Pythagoras' Theorem:

$x^{2} + 4^{2} = 7^{2}$

$x^{2} = 49 - 16$

$x^{2} = 33$

$x = \pm \sqrt{33}$

Since it is a length measure, we only take the positive value

$x = 5.7$

The third side is 5.7 centimeters.

A potter forms a piece of clay into a cylinder. As he rolls it, the length, L, of the cylinder increases and the radius, r, decr

stepan [7]

Answer:

The radius is decreatsing at a rate 0.78 cm per second.

Step-by-step explanation:

We are given the following in the question:

$\dfrac{dl}{dt} = 0.7\text{ cm per second}$

Instant radius,r = 2 cm

Instant length,l = 9cm

The radius of the cylinder decreases.

Volume of cylinder =

$V =\pi r^2l$

Since the volume of the cylinder does not changes, we can write:

$\dfrac{dV}{dt}=0$

Rate of change of volume:

$\dfrac{dV}{dt} = \pi(2r\dfrac{dr}{dt}l + r^2\dfrac{dl}{dt})$

Puttiung values, we get

$0 = \pi(2(2)\dfrac{dr}{dt}(9) + (2)^2(0.7))\\\\\dfrac{dr}{dt}=-\dfrac{4\times 0.7}{4\times 9} \approx -0.78$

Thus, the radius is decreatsing at a rate 0.78 cm per second.
