Complete Question

In ΔVWX, w = 780 cm, ∠X =21° and ∠W=146°. Find the length of x, to the nearest 10th of a centimeter.

Answer:

499.9cm

Step-by-step explanation:

We solve for length x using the Sine rule

w/ sin W = x /sin X

Cross Multiply

x × sin W = w × sin X

x = w × sin X/ sin W

x = 780 × sin 21°/ sin 146°

x = 499.88 cm

Approximately to nearest tenth = 499.9cm

Question 2<br> Find the volume.
garik1379 [7]

Answer:

Volume of cone = 686π/3 or 718.67 in³

Step-by-step explanation:

Given the following data;

Radius, r = 7 in

Height, h = 14 inches

From the diagram, we can see that the object is a cone

To find the volume of a cone;

Mathematically, the volume of a cone is given by the formula;

V = \frac{1}{3} \pi r^{2}h

Where;

V is the volume of the cone.

r is the radius of the base of the cone.

h is the height of the cone.

Substituting into the equation, we have;

Volume = \frac{1}{3} * \frac {22}{7} *7^{2}*14

Volume = \frac{1}{3} * 22 * 7 * 14

Volume = \frac{1}{3} * 2156

Volume = 718.67

Volume of cone = 718.67 in³ or 686π/3 in³

Find the area of a triangle with a base length of 4 units and a height of 5 units. (1 point) 8 square units 9 square units 10 sq
SVETLANKA909090 [29]

Answer:

10 square units

Step-by-step explanation:

Because to get the area of a triangle you cut the base length in half then multiply it by the height, in this case 2.5*4 = 10 square units

A car of m = 1200. kg collides with a tree while traveling 60.0 mph. The collision occurs over a time period of 0.0500 seconds.
goldfiish [28.3K]

Answer:

6.4331 × 10 5N

Step-by-step explanation:

Given the following :

Mass (m) of car = 1200kg

Initial Velocity (u) of car = 60 mph

Final velocity = 0 ( comes to rest)

Velocity in m/s = 60 / 2.24 = 26.785 m/s

Time (t) = 0.0500

Using the relation :

Ft = m(v - u)

Where,

v = final velocity ; u = initial velocity ; t = time ; F = force

F*0.05 = 1200(26.785 - 0)

0.05F = 32142.86 - 0

F = 32142.86 / 0.05

F = 642857.14 N

F = 6.43 × 10^5 N
