Answer:
45
Step-by-step explanation:
Step 1:
2x + 55° + x - 10° = 180° Sum of a Δ
Step 2:
3x + 45° = 180° Combine Like Terms
Step 3:
3x = 135° Subtract 45° on both sides
Step 4:

If a sample of 6 keyboards is randomly selected, what is the probability that at least 5 of these will have a mechanical defect
Answers
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.

tickets?
$225
$200
$125

Answers
Answer:
Step-by-step explanation:
45g + 25s = 485
g + s = 13
45g + 25s = 485
-25g - 25s = -325
20g = 160
g = 8
8 + s = 13
s = 5
25(5)= $125 on same-day tickets

Angles are not necessarily drawn to scale.Given the following:
Answers
Answer:
<x = 31°
Step-by-step explanation:
m<BCA = m<GCJ (vertical angles)
m<BCA = 59° (substitution)
Since line KL is perpendicular to line FG, the angle formed at point B is 90°.
Therefore, m<ABC = 90°
m<BAC + m<ABC + m<BCA = 180° (sum of triangle)
m<BAC + 90° + 59° = 180° (Substitution)
m<BAC + 149° = 180°
m<BAC = 180° - 149°
m<BAC = 31°
<x = <BAC (vertical angles)
m<x = 31° (substitution)

A flat screen television measures diagonally 40 inches and 24 inches in length. What is the width of the television?
Answers
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]

how much kinetic energy does a 4 kg cats have while at 9 m/s
Answers
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.
