Answer:

The width of the Television is 32 inches.

Step-by-step explanation:

It seems as if the hypotenuse of the triangle is 40 inches, and one of the side lengths of it is 24 inches.

a2+b2=c2

So if we square 40 we get 1600, which is c2

If we square 24, we get 576, which is a2.

Then you solve, 576+b2=1600

you get b2=1600

Then you get the square root of both sides which in turn gives you the answer

b=32, which is the width of the television.

Step-by-step explanation:

use the pythagorean theorem c^2 = a^2 + b^2 diagonal is the hypotenuse...

40^2 = 24^2 + b^2

b^2 = 40^2 - 24^2

b =

[tex] b = \sqrt{40 {}^{2} - 24 {}^{2} } [/tex]

Answer:

A. mars, Neptune, earth, Saturn

Step-by-step explanation:

Saturn's diameter is 1.2 × 10^4 which equals 12,000

While Neptune diameter is 5.0 × 10^3 which equals 5000

and so we have all the stats given in the same format and so we can sort them in smallest to biggest as the answer above!

Answer:

162 Joules

Step-by-step explanation:

Remember, the equation for the kinetic energy of an object is:

[tex]K=\frac{1}{2}mv^{2}[/tex]

where m is the mass of the object in kg (kilograms), v is the velocity of the object in m/s (meters per second), and K is the kinetic energy of the object in J (joules).

We are given that the cat's mass is 4 kg. We will use this for m. We are also given that the cat is moving at 9 m/s. This would be it's speed. We can use this for velocity, or v. Plugging in we get:

[tex]K=\frac{1}{2}mv^{2}=\frac{1}{2}(4)(9)^{2}=(2)(81)=162[/tex]

So K, or the kinetic energy, would be 162J.

Answer:

0.1978 is the probability that at least 5 keyboards will have mechanical defect.

Step-by-step explanation:

Solution:

Given:

A repair facility has 25 failed keyboards.

10 keyboards have electrical defect.

15 of which have mechanical defect.

Randomly selected keyboard= 6

The set of A is the set of keyboards with electrical defect.

And  the set of B is set of keyboards with mechanical defect.

N(A U B) = n (A) + n(B) – n (A ∩B)

Probability of at least 5 will have mechanical defect is:

                              = p(  5 mechanical defect  U 6 mechanical defect)

                              = p(5 mechanical defect  ) + p(6 mechanical defect)

                                =(15 C 5 x 10 C1 + 15 C6 X 10C0) / 25 C6

                                = 3003 X 10 / 177100 + 5005 X 1 / 177100

                                = 30030 + 5005 / 177100

                               = 35035 / 177100

                              = 0.1978

0.1978 is the probability that at least 5 keyboards will have mechanical defect.

The answers are A, C and D

The graph that best represents an increasing function is (a) A graph shows a non linear curve that joins the ordered pairs (0, 0), and (2.5, 1), and (4, 3).

For a graph to represent an increasing function, then as the input values increases, the output values must also increase

This means that:

As the x values increases, the y values must also increase

Hence, the graph that best represents an increasing function is (a)

This is so because as x increases from 0 through 2.5 to 4, y increases from 0 through 1 to 3

x = 24

Step-by-step explanation:

Lets isolate x.

Add 16 on both sides.

x-16 = 8

x should be isolated now.

x = 24

It is isolated.

So... x = 24

Venn diagrams gives a visual representation of the distribution of a whole divided into two or more groups using circles. Going by the scale of the Venn diagram given, only the inequalities A, C, E and F must always be true.

Size of brown hair = H

Size of brown eyes = E

Size of those who have both = X

From the Venn diagram given ; we can deduce that H = E

Evaluating the inequalities :

Therefore, only the inequalities A, C, E and F must always be true.
