Mathematics
1 answer:
OLEGan [10]3 years ago
6 0

Answer:

D

Step-by-step explanation:

Lets look at the numbers

sqrt(4) = 2  which is a rational number

sqrt(5)   cannot be simplified, it is an irrational number

-6/5  a ratio of integers, which is the definition of a rational number, so it is a rational number

3.5 = 35/10  a ratio of integers, which is the definition of a rational number, so it is a rational number

.555555 = 5/9   a ratio of integers, which is the definition of a rational number, so it is a rational number


Rational numbers:  sqrt(4), -6/5, 3.5  , .5555(repeating)

Irrational numbers: sqrt(5)

For what values of x is x2 + 2x = 24 true?<br><br> –6 and –4<br> –4 and 6<br> 4 and –6<br> 6 and 4
kolezko [41]
You can solve this 2 ways: plug in all of the options or solve for x.
i going to solve for x.

given: x^2+2x=24     (subtract 24 on both sides to get make it look like x^2+x+1)

x^2+2x-24=0    (now factor x^2+2x-24 out)

<span>x^2+2x-24 --> (x-4)(x+6)
</span>
new equation: <span>(x-4)(x+6)=0   (now make them both equl zero)

new equaions:    </span>x-4=0      x+6=0    <span> (now solve for x for both)

x-4=0        x+6=0
   x=4            x=-6
your <span>answer is 4 and -6.
if you were not taught how to do what i just did then i can message you how to plug those numbers into </span></span><span> x^2+2x=24 to find the answer.</span>

If one circle has a diameter of 20 cm and a second circle has a diameter of 40 cm, what is the ratio of the area of the larger c
taurus [48]

Answer:

The ratio of the area of the larger circle to the area of the smaller circle will be: 4/1 or 4:1        

Step-by-step explanation:

The diameter of a larger circle = d = 40 cm

                                                 r = d/2 = 40/2 = 20 cm

The area of the larger circle = πr²

                                               = 3.14 (20)²

                                                = 3.14 × 400

                                                 = 1256 cm²

The diameter of a smaller circle = 20 cm

                                                   r = d/2 = 20/2 = 10 cm

The area of the smaller circle = πr²

                                                 = 3.14 (10)²

                                                 = 3.14 × 100

                                                 = 314 cm²

Thus,

The area of the larger circle = 1256 cm²

The area of the smaller circle = 314 cm²

Therefore,

The ratio of the area of the larger circle to the area of the smaller circle will be computed as:

  • 1256:314  or   1256/314

reducing the ration into a simpler form

  • 1256/314 = 4/1

Thus, the ratio of the area of the larger circle to the area of the smaller circle will be: 4/1 or 4:1

If ∠CEF is complementary to ∠DCF, then ∠DCF ≅ ∠FEG.
scZoUnD [109]

Answer:

Correct answer is <em>A) Complements of the same angle are congruent.</em>

Step-by-step explanation:

According to Congruent Complement Theorem,

<em><u>" If 2 angles are complementary to the same angle, then they are congruent to each other".</u></em>

Here, ∠CEF is complementary to ∠DCF, hence ∠DCF ≅ ∠FEG.
