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.

A plane traveled 4575 miles with the wind in 7.5 hours and 4275 miles against the wind in the same amount of time. Find the speed of the plane in still air and the
speed of the wind.
The speed of the plane in still air is mph. (Simplify your answer.)
The speed of the wind is mph. (Simplify your answer.)
Answer:
The speed of the plane in still air is 590 mph
The speed of the wind is 20 mph
Step-by-step explanation:
Let's call:
x = Speed of the plane in still air
y = Speed of the wind
The plane traveled d=4575 miles with the wind in t=7.5 h. The speed calculated with this data corresponds to the sum of the speed of the plane and the speed of the wind, thus:
[tex]\displaystyle x+y=\frac{4575}{7.5}=610[/tex]
x + y = 610 [1]
The plane traveled 4275 miles in 7.5 hours against the wind, thus the speed calculated is x - y:
[tex]\displaystyle x-y=\frac{4275}{7.5}=570[/tex]
x - y = 570 [2]
Adding [1] and [2]:
2x = 610 + 570 = 1180
x = 1180 / 2 = 590
From [1]:
y = 610 - 590 = 20
The speed of the plane in still air is 590 mph
The speed of the wind is 20 mph

Cos(-7pi/12)
A. Sqrt 6 + sqrt 2
B. Sqrt 6 - sqrt 2 / 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].

Answer:
C. 0.5
Step-by-step explanation:
If point B is nearest to zero and that far from three, it is going to be 0.5. Not to mention, you can estimate that point is about a half from one.
Answer:
C
Step-by-step explanation:
A - 3.6 is ahead of C, so nope
B - -0.2 is behind A, nope
C - 0.5 works because it seems reasonably distanced (closer to 0 than 3.5)
D - 2 is closer to 3.5, but point b is closer to 0.
Also, if you divide the section between A and C by 7, you can find that 0.5 works because it should be the first section of 0.5
Scale Factor
As a word problem......
A playground is 15 cm wide. After dilation, it is 150 cm wide. What is the scale factor of the dilation?
Answer:
10
My Logic:
if im correct the scale playground is 15cm wide while the real playground is 150 cm wide. That means that the scale playground is 1/10 of the real one or 1/10 scale.

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.
