What do you know about the angles of a right triangle?

A all angles might be right angles.
B only one angle is a right angle and the other two are acute
C one or more angles must be right angles
D only one angle is a right angle and the other two are obtuse

Answer:

x = 5

x = -5

Step-by-step explanation:

2x^2 = 50

2x^2 - 50 = 0

2(x^2 - 25) = 0

2(x^2 + 5x - 5x - 25) = 0

2((x^2 + 5x) + (-5x - 25)) = 0

2(x(x + 5) - 5(x + 5)) = 0

2(x - 5)(x + 5) = 0

x - 5 = 0

x + 5 = 0

x = 5

x = -5

Answer:

80

Step-by-step explanation:

160 x .05 = 8

(5% of 160 is 8)

160 x .5 = 80.

You know you should multiply, because when working with fractions, decimals, and percentages, the word "of" means multiplied by.

Answer:

all negative and positive angle measures.

Step-by-step explanation:

The domain of the cosine function is: all negative and positive angle measures.

"It is a set of all possible input values for which a function is well defined."

We know,

A cosine function i.e., f(x) = cos(x) is defined for any real value of x.

This means, the domain of the cosine function is, all negative and positive angle measures.

Therefore, the correct answer is option (A).

[tex]\sqrt[4]{x^{7} }[/tex]

Step-by-step explanation:

this is the same concept basically as simplifying [tex]\sqrt{x}[/tex] into [tex]x^{\frac{1}{2} }[/tex]. You can see that the denominator is in front of the radical and that any numbers in the numerator are the power of the number underneath.

Answer:

1. Split up the linear term: [tex]2x^{2}[/tex]+2x-3x-3

2. Group terms that have common factors: ([tex]2x^{2}[/tex]+2x)+(-3x-3)

3. Factor out the greatest common factor: 2x (x+1) -3 (x+1)

4. Factor out the greatest common factor: (x+1)(2x-3)

Answer: (x+1)(2x-3)

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

Z-score may be defined as a position of the raw score in regard to the distance from its mean when it is measured in the units of standard deviation. Z-score is considered as positive, when the values is above the mean. And when it is below the mean, it is considered as negative.

Another name of a z-score is standard score. Z-score can be measured using the relation :

[tex]$z=\frac{x-\mu}{\sigma}$[/tex]

where, z = z-score

           x = raw score

           μ = population mean

           σ = population standard deviation

Thus from the formula we can see how many standard deviation the score is from a men of the distribution by looking at the corresponding z-score.

Answer:

12

Step-by-step explanation:

20-60=12

Answer:

∠1 is 33°

∠2 is 57°

∠3 is 57°

∠4 is 33°

Step-by-step explanation:

First off, we already know that ∠2 is 57° because of alternate interior angles.

Second, it's important to know that rhombus' diagonals bisect each other; meaning they form 90° angles in the intersection. Another cool thing is that the diagonals bisect the existing angles in the rhombus. Therefore, 57° is just half of something.

Then, you basically just do some other pain-in-the-butt things after.

Since that ∠2 is just the bisected half from one existing angle, that means that ∠3 is just the other half; meaning that ∠3 is 57°, as well.

Next is to just find the missing angle ∠1. Since we already know ∠3 is 57°, we can just add that to the 90° that the diagonals formed at the intersection.

57° + 90° = 147°

180° - 147° = 33°

∠1 is 33°

Finally, since that ∠4 is just an alternate interior angle of ∠1, ∠4 is 33°, too.

Answer:

Bigcity United lost 12 games.

Step-by-step explanation:

Since you know the percentage of games Bigcity United won, first you need to determine the percentage of games that they lose by subtracting the percentage of games they won from 100%:

100%-60%=40%

Now, you know that they lost 40% of the games and you can calculate 40% of the number of games they played last season:

30*40%=12

According to this, the answer is that Bigcity United lost 12 games.

Answer:

Cats = 34

Dogs = 37

birds = 25

Step-by-step explanation:

Let :

c = cats

d = dogs

b = birds

from the question, the following equation can be gotten

d = 3 + c  eqn 1

b = c - 9   eqn 2

c + d + b = 96 eqn 3

substitute for b and d in equation 3

3 + c + c - 9 + c = 96

3c - 6 = 96

3c = 102

c = 34

Substitute for d in eqn 1

d = 3 + 34 = 37

Substitute for b in eqn 2

34 - 9 = 25

Answer:

the answer is c. 9

Step-by-step explanation:

20=2x+2

18=2x

x=9

Answer:

C

Step-by-step explanation:

Given f(x) = 2x + 2 and f(x) = 20, then equate right sides, that is

2x + 2 = 20 ( subtract 2 from both sides )

2x = 18 ( divide both sides by 2 )

x = 9 → C
