Answer:
first is 1/8, second is 1/10, third is 1/15, and fourth is 1/16
Step-by-step explanation:
1/2 divided by 4 = .5/4
.5/4 = 0.125
.125 = 1/8
1. 1/8
1/5 = .2
.2/2 = .1
.1 = 1/10
2. 1/10
since 1/3 would be a repeating term, you can change 5 to 5/1
3/1 = 3
1/5 = .2
.2/3 = 1/15
3. 1/15
1/4 divided by four = 1/4 divided by 1/4
1 x 1 = 1
4 x 4 = 16
4. 1/16
Find the measure of line segment DF.
A) 12
B) 13
C) 14
D) 15
As per the Intersecting Chords theorem, if two chords cross in a circle, the products of the chord segments' measures are equal. The measure of the line segment is DF is 14 units.
What is Intersecting Chords theorem?If two chords cross in a circle, the products of the chord segments' measures are equal.
As per the Intersecting Chords theorem, the product of DF and FB will be equal to the product of CF and FA, therefore,
DF×FB = CF×FA
(x+8) × 8 = 16 × 7
(x+8) = (16×7)/8
(x+8) = 14
Hence, the measure of the line segment is DF is 14 units.

What is a right angle triangle?A right angle triangle is a triangle that has one of its sides as 90 degrees. The situation forms two right angle triangle.
Using cosine law,
17² = 14² + 22² - 2 × 14 × 22 cos C
289 - 196 - 484 = -616 cos C
-391 = -616 cos C
divide both sides by -616
cos C = -391 / -616
cos C = 0.63474025974
C = cos⁻¹ 0.63474025974
C = 50.59929658
C = 51 degrees.

Step-by-step explanation:
When sine and cosine are equal to each other, they have the same value. We know that tan (A) = sin (A) / cos (A). If sin (A) and cos (A) are the same, and any number divided by itself equals 1, the final answer must be tan (A) = 1.

Answer: 480 sq ft
Step-by-step explanation:
for two rectangles on right do 8*16 =128*2 = 256
the rectangle on the right is also 128
total of all rectangles is 384 ft
now for the triangles
formula: 1/2 b*h
1/2 * 16*6 = 48
multiply that by 2 for both triangles
you have 96
add that to total and you get
480 sq ft
Answer:
Step-by-step explanation:
The hypotenuse of the triangles is the length of the rectangles so the length of the rectangles is 16 ft. The width of the rectangles is 8 ft. There are 3 rectangles so the surface area of them is:
(16*8)*3 = 384[tex]ft^{2}[/tex]
The area of a triangle is base times height divided by two. Here, the height of the two triangles is 6 ft and the base is 16 ft. So, the area of the two triangles is:
[tex]\frac{6*16*2}{2}[/tex] = 16*6 = 96 [tex]ft^2[/tex]
Add the two areas together to get the surface area.
384[tex]ft^2[/tex] + 96[tex]ft^2\\[/tex] = 480[tex]ft^2[/tex]
Hence, the surface area of the triangular prism is 480[tex]ft^2[/tex]

If y=2x-8 what is the minimum value of the product xy
The minimum value of the product is -8.
What is the minimum value?The minimum value is the y value of the lowest point on the graph.
The function y = 2x-8 and we have to find the minimum value of the XY.
Plugging the value of y in the product;
[tex]\rm f(x)=x(2x-8)\\\\f(x)=2x^2-8x[/tex]
f(x) represents an upward parabola and we know that for an upward parabola, the minimum point is the vertex.
So in order to find the minimum value, we find the y coordinate of the vertex of the parabola.
The x-coordinate of the parabola is given by;
[tex]\rm = \dfrac{-b}{2a}\\\\=\dfrac{-8}{2\times 2}\\\\ =\dfrac{-8}{4}\\\\=-2[/tex]
The y -coordinate of the parabola is;
[tex]\rm f(x)=2x^2-8x\\\\f(2)=2(2)^2-8(2)\\\\f(2)=2\times 4-16\\\\ f(2)=8-16\\\\ f(2)=-8[/tex]
The vertex is (2,-8)
Hence, the minimum value of the product is -8.

Of the following three Greek philosophers, who lived the longest?why?
Aristotle: born in Stagira in 384 BCE, died in 322 BCE.
Pythagoras: born in Samos around 580 BC, died around 495 BC.
Plato: born in Athens in 428 BCE, died in 348 BCE.
Answer:
Pythagoras
Step-by-step explanation:
To figure out how old each philospher was, we can find the difference between their birth and death years.
For Aristotle: 384 - 322 = 62 years old
For Pythagoras: 580 - 495 = 85 years old
For Plato: 428 - 348 = 80
85 > 80 > 62
So, Pythagoras lived the longest out of these three Greek philosophers.
