The length of one side of a square = 8 cm
To find out the length of one side of a square that is inscribed in a circle that has a radius of 4 cm:
Since the square is inscribed in the circle, a diagonal
of the square is a diameter of the circle.
The diameter of the circle = 2 x radius = 8 cm .
The diagonal of the square = 8 cm.
The diagonal of a square is (length of a side) x (√8).
Side x √8 = 2√2 cm
Divide each side by √2:
Side = 8 cm / √2 = 8 √2 / √2 = 8 cm.
Hence the answer is the length of one side of a square = 8 cm

s=l-r l solve for r ty for your answer
The modulus of |-r| means that it is an absolute value. Therefore, the answer is "s".
What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.
|x| = -x, x < 0.
It measures the distance of a point x to the origin, thus, |-2| = |2| = 0, and has vertex(turning point) at (0,0). Then the range is from the y-coordinate of the vertex to positive infinity.
WE have given as s=l-r l
When we add a positive or negative number in between the lines then; it is;
|-r| goes through = -r = -s
|-r| goes through = r = s
The modulus of |-r| means that it is an absolute value. Therefore, the answer is "s".

The vertex form of the expression is y = (x-4)²-1
What is vertex form?
In this little tutorial, we'll look at how to change a standard form into a vertex form and vice versa. A parabola's equation can be shown in various ways, including standard form, vertex form, and intercept form. Any of these forms can be changed into either of the other two depending on the situation. We will discover how to convert in this article.
The vertex form is y = (x-h)² + k
The only term with x with 2hx from the vertex form and 8x in order to form a standard form.
The given expression is x²-8x+15,
So 2hx = -8x
h = 4
Substituting in the original expression we will have
y = (x-4)²-1
Hence this is in vertex form.

An arithmetic sequence has the following
properties:
i) Its 6th term is 15.
ii) Its 9th term is three times the 2nd term.
Find the 100th term of this sequence.
The 100th term of the arithmetic sequence is 203.
Let the first term of the arithmetic sequence be a and the common difference be d.
The general term of the sequence is given by
[tex]T_{n} = a + (n-1)d[/tex]
It is given that the 6th term is 15, we have :
[tex]T_{6} = a +5d[/tex]
a + 5d = 15......equation(1)
It is given that the 9th term is three times the 2nd term, we have :
[tex]T_{9} = 3*T_{2} \\a + 8d = 3(a +d)\\a + 8d = 3a +3d\\a -3a = 3d -8d = -5d\\-2a = -5d\\2a = 5d\\a = \frac{5d}{2}[/tex]
Putting this value in equation(1)
[tex]\frac{5d}{2} + 5d = 15 \\\\5d + 10d = 30\\15d= 30\\d = \frac{30}{15} = 2[/tex]
a = 5*2/2 = 5
Hence, the first term is 5 and the common difference is 2.
Now, evaluating the 100th term of the sequence, we have :
[tex]T_{n} = a +(n-1)d\\T_{100} = a +99d\\T_{100} = 5 +99*2 = 5 +198 = 203[/tex]
Hence, the 100th term of the arithmetic sequence is 203.

If John Carlo has 4 times as many nickels as quarters and they have a combined value of 270 cents, how many of each coin does he have?
There 6 quarters and 24 nickels of each coins that John Carlo has.
How to calculate for the number of each coins.There are 5 cents in a nickel and 25 cents in a quarter. Let us represent the number of quarters as x so that the number of nickels that John Carlo has will be 4x.
Thus, 4x(5 cents) + x(25 cents) = 270 cents
20x cents + 25x cents = 270 cents
45x cents = 270 cents
divide through by 45
x = 270/45
x = 6
and thus there are 4(6) = 24 nickels.
Therefore, John Carlo has 6 quarters and 24 nickels each of coins.

Which statement describes its current depth? A It is 692 feet below sea level, because -350 + (-150) + 132 + (-179) + (-145) = -692. B It is 8 feet below sea level, because 350 + (-150) + 132 + (-179) + (-145) = 8. c It is 256 feet below sea level, because 350 + (-150) +..(-132) + (-179) + (-145) = -256. D It is 342 feet below sea level, because 150 132 179 145 = 342. AI B ci D
We have the next information
A submarine Is at a depth of 350 feet below sea level means -350
First, it goes down 150 feet. means -150
Next, it goes up 132 feet. means +132
Then, it goes down 179 feet. means -179
Finally, it goes down 145 feet means -145
then we have the next operations
-350+(-150)+132+(-179)+(-145)=-692
The sing minus means that It is below the sea level
therefore the correct choice is
A It is 692 feet below sea level, because -350 + (-150) + 132 + (-179) + (-145) = -692.

An architect makes a model of a new house. The model shows a tile patio in the backyard. In the model, each tile has length 2/3 in. and width 1/2. The actual tiles have length 1/2 ft and width 3/8 ft. What is the ratio of the length of a tile in the model to the length of an actual tile? What is the ratio of the area of a tile in the model to the area of an actual tile? Use pencil and paper. Describe two ways to find each ratio. The ratio of the length of a tile in the model to the length of an actual tile is?
Ratio of the length of a tile in model to length of actual tile is 1/9 and Ratio of Area of tile to area of actual tile is 1/ 81
Given,
Length of each tiles = 2/3 in
Width of each tiles = 1/2 in
The actual tiles have length = 1/2 ft = 6 in {1 foot = 12 inch }
Width of actual tiles = 3/8 ft = 4.5 in
Ratio of length of tile in the model to the length of an actual tile =
length of tile / length of an actual tile
= [tex]\frac{2/3}{6} = \frac{1}{9}[/tex]
Area of tiles = area of rectangle = length × width
= 2/3 × 1/2
= 1/3 in²
Area of actual tile = 6 × 4.5 = 27 in²
Ratio of the area of a tile in the model to the area of an actual tile =
Area of tile / area of actual tiles
= [tex]\frac{1/3}{27} = \frac{1}{81}[/tex]
Another way of finding ratio is by Dilation ,
Ratio of lengths = 1 / 9
according to the property of dilation,
Ratio of area of tiles to area of actual tiles = (1/9)² = 1/81
