Answer:

i believe the answer is 30

Step-by-step explanation:

For this case we must divide the following expression:

[tex]\frac {413} {129}[/tex]

The expression can not be simplified. When dividing we have that its decimal form is given by:

3,201550

If we convert to a mixed number we have:

[tex]3 \frac {26} {129}[/tex]

Verifying:

[tex]3 \frac {26} {129} = \frac {129 * 3 + 26} {129} = \frac {413} {129}[/tex]

Answer:

[tex]3 \frac {26} {129}[/tex]

The value of (-14°)-2 is the reciprocal of 196 since the negative exponent indicates that we should take the reciprocal of the base raised to the positive exponent. The correct answer is 1/196.

The question asks for the value of (-14°)-2, which represents a mathematical expression that requires simplification using exponent rules. The notation a-n means that you should take the reciprocal of an, which in this case is the reciprocal of (-14°) squared. When squaring a negative degree value, the square of a negative number is positive, so (-14°)2 = 196°. Therefore, taking the reciprocal of 196° gives us 1/196.

The value of (-14°)-2 is 1/196.

Explanation:

The triangles are similar triangles (we can use the AA similarity theorem to prove this). So the vertical sides pair up, and the horizontal sides pair up, to form the proportion below

x/4.5 = 8/6

Note the order of the terms. I'm dividing the upper triangle's sides by the corresponding lower triangle's sides. Cross multiply and solve for x

x/4.5 = 8/6

6x = 4.5*8

6x = 36

x = 36/6

x = 6

Answer: X < -3

Step-by-step explanation:

-15x - 3 > 42

-15x - 3 + 3 > 42 + 3

-15x > 45

-15x/-15 > 45/-15

Since we are dividing by a negative, we flip the >

x < -3

So, let's check

-4 < -3

-15*-4 - 3 > 42

60 - 3 > 42

57 > 42

Now, let's see if -3 will work.

-15*-3 - 3 > 42

45 - 3 > 42

42 > 42 (False)

Okay, now let's try 4

-15*4 - 3 > 42

-60 - 3 > 42

-63 > 42

This is false, so it is x < -3

The correct answer is x < -3

Explanation:

To solve our equation we first need to set out our equation, -15x – 3 > 42. Next, we add 3 to both sides of our equation, -15x - 3 + 3 > 42 + 3 = -15x > 45. Then, we multiply both sides by -1(Or in other words, reverse the inequality), -15x * -1 > 45 * -1 = 15x < -45. And then, we divide both sides by 15, 15x/15 < -45/15 = x < -3. Finally, we have our answer of x < -3.

Final answer:

The inequality representing all possible values of b, the number of bottles of water Jamie can buy, is b ≤ 13, as Jamie has $16.45 left to spend after buying nine candy bars and each bottle costs $1.25.

Explanation:

The student must buy nine candy bars, which cost $0.95 each. The total cost for the candy bars is 9 * $0.95 = $8.55. Jamie has $25.00 to spend, so after buying the candy bars, she will have $25.00 - $8.55 = $16.45 left for bottles of water. Each bottle of water costs $1.25, so the number of bottles she can buy is represented by the inequality $1.25b ≤ $16.45, where b is the number of bottles of water Jamie can purchase.

Now, let's solve this inequality for b. Dividing both sides of the inequality by $1.25 gives us b ≤ 13.16. Since Jamie can't buy a fraction of a bottle, she must buy at most 13 bottles of water.

Therefore, the inequality representing all possible values of b (i.e., the number of bottles of water Jamie can buy) is b ≤ 13.

Answer:

1% of 4000 + 4% of B = 2% of (4000 + B)

40 + 0.04*B = 0.02( 4000 + B)

40 + 0.04* B = 80 + 0.02*B

40 + 0.04*B - 80 - 0.02B = 0

0.02*B - 40 = 0

0.02*B = 40

2B = 4000

B = 2000

Step-by-step explanation:

Plant B produced 1000 panels.

The total number of defective panels from Plant A is 7% of 6000,

= (7/100) x 6000

= 420 panels.

and, total number of defective panels from Plant B is 2% of x,

= (2/100) x

= (1/50) x.

The overall number of defective panels from both plants is 4% of the total number of panels

= (4/100)(6000 + x)

= (1/25) (6000 + x).

Now, set up the equation:

420 + (1/50)  x = (1/25) (6000 + x)

To solve for x, we can multiply both sides of the equation by 50 * 25 to eliminate the fractions:

50 . 25 . 420 + 50 x = 25 (6000 + x)

125000 + 50x = 150000 + 25x

50x - 25x = 150000 - 125000

25x = 25000

x = 25000 / 25

x = 1000

Therefore, Plant B produced 1000 panels.

Answer:

13/2 is 6.5 as a fraction

Answer:

π4;3π4

Step-by-step explanation: Trig table gives:

sinx=√22 --> arc x=π4

Unit circle gives another arc x that has the same sin value:

x=π−π4=3π4

The exact value of [tex]\(\arcsin(-2\sqrt{2})\)[/tex] is not defined within the real numbers because the sine function has a range of [tex]\([-1, 1]\)[/tex], and the argument [tex]\(-2\sqrt{2}\)[/tex] lies outside this interval. The arcsine function, [tex]\(\arcsin(x)\)[/tex], is only defined for [tex]\(x\)[/tex] in the interval [tex]\([-1, 1]\)[/tex] .

To illustrate, the sine function reaches its maximum value of [tex]\(1\)[/tex] at [tex]\(\frac{\pi}{2}\)[/tex] and its minimum value of [tex]\(-1\)[/tex] at [tex]\(-\frac{\pi}{2}\)[/tex]. Any value outside the interval [tex]\([-1, 1]\)[/tex] is not within the domain of the inverse sine function. Therefore,[tex]\(\arcsin(-2\sqrt{2})\) does not have a real value.[/tex]

However, if we were to consider complex numbers, we could use Euler's formula and the definition of the complex logarithm to find a complex value for [tex]\(\arcsin(-2\sqrt{2})\)[/tex]. The general formula for the arcsine of a complex number [tex]\(z\)[/tex] is given by:

[tex]\[ \arcsin(z) = -i \ln\left(iz + \sqrt{1 - z^2}\right) \][/tex]

For [tex]\(z = -2\sqrt{2}\)[/tex], we would have:

[tex]\[ \arcsin(-2\sqrt{2}) = -i \ln\left(-2i\sqrt{2} + \sqrt{1 - (-2\sqrt{2})^2}\right) \][/tex]

Simplifying the expression under the square root:

[tex]\[ \sqrt{1 - (-2\sqrt{2})^2} = \sqrt{1 - 8} = \sqrt{-7} \][/tex]

Since [tex]\(\sqrt{-7} = i\sqrt{7}\)[/tex], we can continue the calculation:

[tex]\[ \arcsin(-2\sqrt{2}) = -i \ln\left(-2i\sqrt{2} + i\sqrt{7}\right) \][/tex]

This expression involves the complex logarithm, which is multi-valued due to the periodicity of the complex exponential function. Therefore, the value of [tex]\(\arcsin(-2\sqrt{2})\)[/tex] in the complex plane is not unique and requires careful handling of the branch cuts of the logarithm function. However, as stated earlier, within the realm of real numbers, [tex]\(\arcsin(-2\sqrt{2})\)[/tex] is undefined.

Answer:  

[tex]\frac{(L x M)}{6}[/tex]

Step-by-step explanation:  

The greatest common factor is the greatest number that will divide two values. We have two values L and M. Each has numbers which multiply together to give the number. The highest value or most in common they share is 6. This is the GCF.

The least common multiple is the smallest positive number which is a multiple of the two. This means both L and M divide into it evenly.

We know L x M is a multiple because L and M will be factors of it. But we don't know its the least.

As an example if L= 42 and M = 60, they have GCF 6. We can multiply them to find a multiple 42 x 60 = 2520 but we don't know this is the smallest or least multiple we can find. If we divide by the GCF, 2520/6=420. Interestingly, 42 x 10 =420 and 60 x 7 =420. This means 420 is the least common multiple.  

We can multiply (L x M) and then divide by the GCF of L & M to find the least common multiple.

[tex]\frac{(L x M)}{6}[/tex]

Answer:

2.  No it is not direction variation

3. This is direct variation with the constant being 2

Step-by-step explanation:

The equation for direct variation is y=kx

2.  8y = 3x+1

Divide each side by 8

8y/8 = 3x/8 + 1/8

y = 3/8 x + 1/8

We are adding 1/8 to each time so it is not direct variation

3.  12y = 24x

Divide each side by 12

12y/12 = 24x/12

y = 2x

This matches y= kx, where k=2

This is direct variation with the constant being 2
