Answer:
Write 6.384 correct to 1 decimal place ?=6
Answer:
6.4
Step-by-step explanation:
Rounding 6.384 to one decimal place would be the same as rounding it to the nearest tenth. The tenth in this number is 3. To round a number up, look at the number to the right of it - if the number is 5 or greater, then you increase the value of the number you're rounding by 1. If the number to the right of it is 4 or less, then the value of the number you're rounding stays the same.
In this case, the number we're rounding is 3 and the number to the right of it is 8. Since 8 is greater than 5, we have to increase the value of 3 by 1, which means that the number in the tenths position is now 4.
The number rounded to one decimal place is 6.4.

C. Sqrt 2 - sqrt 6
Sqrt 2 - sqrt 6 / 4
Answer:
[tex]\displaystyle \cos\left(-\frac{7\,\pi}{12}\right) = \frac{\sqrt{2} - \sqrt{6}}{4}[/tex].
Step-by-step explanation:
Convert the angle [tex]\displaystyle \left(-\frac{7\, \pi}{12}\right)[/tex] to degrees:
[tex]\displaystyle \left(-\frac{7\, \pi}{12}\right) = \left(-\frac{7\, \pi}{12}\right) \times \frac{180^\circ}{\pi} = -105^\circ[/tex].
Note, that [tex]\left(-105^\circ\right)[/tex] is the sum of two common angles: [tex]\left(-45^\circ\right)[/tex] and [tex]\left(-60^\circ\right)[/tex].
[tex]\displaystyle \cos\left(-45^\circ\right) = \cos\left(45^\circ\right) = \frac{\sqrt{2}}{2}[/tex].[tex]\displaystyle \cos\left(-60^\circ\right) = \cos\left(60^\circ\right) = \frac{1}{2}[/tex].[tex]\displaystyle \sin\left(-45^\circ\right) = -\sin\left(45^\circ\right) = -\frac{\sqrt{2}}{2}[/tex].[tex]\displaystyle \sin\left(-60^\circ\right) = -\sin\left(60^\circ\right) = -\frac{\sqrt{3}}{2}[/tex].By the sum-angle identity of cosine:
[tex]\cos(A + B) = \cos(A)\cdot \cos(B) - \sin(A) \cdot \sin(B)[/tex].
Apply the sum formula for cosine to find the exact value of [tex]\cos\left(-105^\circ \right)[/tex].
[tex]\begin{aligned}\cos\left(-105^\circ \right) &= \cos\left(\left(-45^\circ\right) + \left(-60^\circ\right)\right) \\ &= \cos\left(-45^\circ\right) \cdot \cos\left(-60^\circ\right)\right) - \sin\left(-45^\circ\right) \cdot \sin\left(-60^\circ\right)\right) \\ &= \frac{\sqrt{2}}{2} \times \frac{1}{2} - \left(-\frac{\sqrt{2}}{2}\right)\times \left(-\frac{\sqrt{3}}{2}\right) = \frac{\sqrt{2} - \sqrt{6}}{4}\end{aligned}[/tex].
[tex]\displaystyle \left(-\frac{7\, \pi}{12}\right) = \left(-\frac{7\, \pi}{12}\right) \times \frac{180^\circ}{\pi} = -105^\circ[/tex]. In other words, [tex]\displaystyle \left(-\frac{7\, \pi}{12}\right)[/tex] and [tex]\left(-105^\circ\right)[/tex] correspond to the same angle. Therefore, the cosine of [tex]\displaystyle \left(-\frac{7\, \pi}{12}\right)\![/tex] would be equal to the cosine of [tex]\left(-105^\circ\right)\![/tex].
[tex]\displaystyle \cos\left(-\frac{7\,\pi}{12}\right) = \cos\left(-105^\circ\right) = \frac{\sqrt{2} - \sqrt{6}}{4}[/tex].

Can someone answer 7-11 for me by 12:00AM
Answer:
Step-by-step explanation:
7). x + y = 4 ⇒ y = 4 - x -----> xy = - 96
x(4 - x) = - 96 ⇔ x² - 4x - 96 = 0
D = ( - 4)² - 4(1)(- 96) = 400 = (20)²
[tex]x_{1}[/tex] = (- ( - 4) - 20) ÷ 2(1) = - 8
[tex]x_{2}[/tex] = ( - ( - 4) + 20) ÷ 2 = 12
Numbers are - 8 and 12
8). It's your turn now. You can do it
9). x² - 5x + 3 = 0
0 < [tex]x_{1}[/tex] < 1
4 < [tex]x_{2}[/tex] < 5
10). - x² + 3x + 1 = 0
-1 < [tex]x_{1}[/tex] < 0
3 < [tex]x_{2}[/tex] < 4
11). x² + 2x - 2 = 0
- 3 < [tex]x_{1}[/tex] < - 2
0 < [tex]x_{2}[/tex] < 1

Greatest common factor 16 and 100
Answer:
4
Step-by-step explanation:
The greatest common factor (GCF)
The greatest common factor of 16 and 100 is 4, and it represents the largest number that can evenly divide both 16 and 100.
Here,
To find the greatest common factor (GCF) of two numbers, we need to identify the largest number that can evenly divide both numbers.
Here's the step-by-step process to find the GCF of 16 and 100:
Step 1: List the factors of each number.
The factors of 16 are 1, 2, 4, 8, and 16.
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.
Prime factorization of 16:
16 = 2 * 2 * 2 * 2
Prime factorization of 100:
100 = 2 * 2 * 5 * 5
Step 2: Identify the common factors.
The common factors of 16 and 100 are 1, 2, 4.
Step 3: Find the greatest common factor.
Among the common factors, the greatest common factor (GCF) is the largest one, which is 4.
So, the GCF of 16 and 100 is 4.
In conclusion, the greatest common factor of 16 and 100 is 4, and it represents the largest number that can evenly divide both 16 and 100.

Find the value of x in each case:
Answer:
x = 17
Step-by-step explanation:
We are going to call the missing angle in triangle EDC, "y"
x+y+100=4x+49+y
Eliminate the "y" on both sides
x+100=4x+49
move the x by subtracting the x on the left from the right
100= 3x +49
Move the numbers by subtracting 49 from 100
51 = 3x
Divide both sides by 3
17=x
Answer:
x=17
Step-by-step explanation:
Hello! There are a few important pieces of information you need to keep in mind before trying to solve this problem:
The angles in a triangle ALWAYS add up to 180 degrees.All vertical angles are congruent (I have attached a photo incase you aren't away of what vertical angles are)Now that we know these two pieces of information, we can begin to set up our problem. Because the angles in a triangle always add up to 180, we can set up the problem as follows:
x + 100° + ∠DCE = 4x + 49° + ∠ACB
Now this is where the vertical angles come in. Angles ∠DCE and ∠ACB are vertical, which makes them congruent. Since they are the same value, we can subtract them from either side of the equation. (NOTE: We can only do this because they are the same value. Subtracting angles of different values will mess up your answer!!!)
Now, we have the same problem in much simpler terms. We can now simplify it in order to get x.
4x + 49 = x + 100 (subtract 49 from both sides)
4x = x + 51 (subtract x from both sides)
3x = 51 (divide both sides by 3)
x = 17 (FINAL ANSWER)

Please help me so I can help my little sister
Answer: Valentina measured incorrectly.
Step-by-step explanation: 1 feet equals to 12 inches. If you substitute this value for all the other values like 5 ft and 8 inches (Noah's measurement). Firstly, 5 multiplied by 12 is 60, then you would add 8 to it. Caleb already measured the same amount of inches as Noah so we can just leave that one. Same with Mary, 3 * 12 inches = 36 plus 32 which is also 68. Finally, we are left with Valentina in which she has 2 * 12 inches =24 plus 48 which is 72, not 68. Hence, Valentina measured incorrectly.
