Answer:
39.6534
Step-by-step explanation:
You divide 4005 by 101 and find the numbers that repeat as a decimal. In this case, the repeating decimals are 6534.
6.) The perimeter of a square is 12√5 cm. Find the length of each side and the area of the
square.
the perimeter Is equal to the length of each side moltiplicated for 4, so the length of each side Is: l=P/4=12√5/4=3√5.
The area of the square Is the square of the length of each side, so: A=12√5x12√5= 144x5 (at the moment i haven't a calculatour to use)

If the sixth term in a geometric sequence is 1/625
and the common ratio is 1/5 find the explicit formula of the sequence
aₙ = 5*(1/5)^(n - 1) is the explicit formula of the sequence.
What is Sequence and example ?
A sequence is a list of elements that has been arranged in a certain way. As an illustration, 3, 7, 11, 15,... is a sequence because it follows a pattern in which each phrase is produced by adding 4 to the one before it.The recursive relation for a geometric sequence is
aₙ = aₙ₋₁*R
where R is the common ratio.
We could write this in a general form as:
aₙ = a₁*(R)^(n - 1)
where a₁ is the first term of the sequence.
In this case we know that:
R = 1/5
And that:
a₆ = 1/625
Then we can replace these values in the above relation to get:
a₆ = (1/625) = a₁*(1/5)^(6 - 1) = a₁*(1/5^5) = a₁*(1/3125)
1/625 = a1*(1/3125)
(3125/625) = a1 = 5
Then the formula will be:
aₙ = 5*(1/5)^(n - 1)

Part A: What is the measure of angle x? Show your work.
Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal.
The value of the angle x is equal to 53°
What is the Measure of the angle?
A) From the image attached, we can solve for the angles as follows;
m ∠RPB = 180 - 115 = 65°
Thus, the angle m∠x = 180° - 65° - 62°
= 53°
B) m∠RPB + m∠PRD = 180° (Internal angle between 2 parallel lines are equal).
Second line:
The 3 angles x, 62 and 65 degrees are all on the same straight line (AB), so they sum to 180 degrees.

Write a negation for each statement:
1. All squares are rectangles
2. There exists a segment that has no midpoint
Answer:
1. There exists at least one square that is not a rectangle.
2. Every segment has a midpoint.
Step-by-step explanation:
1.The given statement is: "All squares are rectangles". We have to find the negation of the statement. The statement that gives the negative meaning of the given statement is called the negation of the given statement. So the negation of the given statement is, "There exists at least one square that is not a rectangle".
2.Every segment has a midpoint.
The measures of two vertical angles are 32° and (2x + 2)°. Find the value of x
Answer:
x = 15
Step-by-step explanation:
Vertical angles, also called opposite angles sometimes, are angles that across from each other.
They are congruent meaning they have equal measurement
We can write the following equation based on these information to find the value of x :
2x + 2 = 32 subtract 2 from both sides
2x = 32 divide both sides by 2
x = 15

A human hair has an average diameter of 2.5 * 10 ^ - 5 meters. What is the maximum number of human hairs that could fit side by side (without overlapping) on a microscope slide that is 50 millimeters wide? Write your answer in scientific notation.
(A) 2 × 10 ^ 3
(B) 2 × 10 ^ 5
(D) 10 ^ - 3
(C) 2 × 10 ^ 6
===========================================
Explanation:
Let's find the width of the microscope slide in meters.
1000 mm = 1 m
1 mm = 1/1000 m
1 mm = 0.001 m
50*(1 mm) = 50*(0.001 m)
50 mm = 0.05 m
50 mm = 5 × 10^(-2) m
The microscope slide is 5 × 10^(-2) meters across. Divide this over the width of one hair.
5 × 10^(-2) ÷ 2.5 × 10^(-5)
(5/2.5) × 10^(-2 - (-5) )
2 × 10^(-2 + 5)
2 × 10^3
This converts to the number 2000. So we could have 2000 strands of hair side by side.
Answer:
(A) 2 * 10^3.
Step-by-step explanation:
50 millimeters = 0.05 m
= 5 * 10^-2 meters.
So, we divide this by the diameter of 1 hair:
= (5 * 10^-2) / (2.5 * 10 ^ - 5)
= (5/2.5) * (10/^-2 / 10^-5)
= 2 * 10^(-2-(-5))
= 2 * 10^3.

The weight of a gold bar varies directly with its volume. If a 40 cm³ bar weighs 772 grams, how much will a 100 cm³ bar weigh?
Density is a material's intrinsic (intrinsic) property that depends on how much it occupies a particular space and possibly on temperature.
Density is expressed in units of mass divided by volume. The International Standard Unit (SI) is the kilogram per cubic meter ("cube") or kg/m3. Some commonly used density units are grams per cubic centimeter, or we can also express it as g/cm3; it is more widely used in laboratories.
Mass and volume are related by a term called density.
The formula gives the relation between the mass and the density of an object:
Density = Mass/ Volume
We can extract the desired quantity from this formula, and here it is mass, so,
Mass = Density x Volume
So, by using the above information, 100 cm^3 bar weighs 1930gm.

b
Divide (5,000,000 / 6.7 x 10^-7) = (5 x 10^6) / (6.7 x 10^-7) = (5 / 6.7) x (10^(6 - 7)) = .74 x 10^-1 = 0.074 kg
c
Multiply (5,000,000 x 6.7 x 10^-7) = (5 x 10^6) x (6.7 x 10^-7) = (5 x 6.7) x (10^(6 + 7)) = 33.5 x 10^13 = 3.35 x 10^14 kg
d
Multiply (5,000,000 x 6.7 x 10^-7) = (5 x 10^6) x (6.7 x 10^-7) = (5 x 6.7) x (10^(6 + - 7)) = 33.5 x 10^-1 = 3.35 kg
The weight of the bag she brings home is; D: Multiply (5,000,000 x 6.7 x 10^-7) = (5 x 10^6) x (6.7 x 10^-7) = (5 x 6.7) x (10^(6 + - 7)) = 33.5 x 10^-1 = 3.35 kg
How to use scientific notation?We are told that Maria wanted to bring back 5 million kg of sand from her trip to the beach. Thus;
Amount of sand she wanted to bring out = 5,000,000 kg = 5 * 10⁶ kg
Now, we are told that each grain of sand weighs 6.7 * 10⁻⁷ kg. Thus, the total amount of sand she brings home is;
(5 * 10⁶) * (6.7 * 10⁻⁷) = (5 * 6.7) * (10⁶ ⁻ ⁷) = 33.5 * 10⁻¹ = 3.35 kg
Thus, the correct answer is; Multiply (5,000,000 x 6.7 x 10^-7) = (5 x 10^6) x (6.7 x 10^-7) = (5 x 6.7) x (10^(6 + - 7)) = 33.5 x 10^-1 = 3.35 kg

Simplify each complex fraction. 1/x y - 1/y² / 1/x²y - 1/x y²
The simplified form of given complex fraction is (1/xy - 1/y²) / (1/x²y - 1/xy²) = x
In this question,
we have been given a fraction 1/x y - 1/y² / 1/x²y - 1/x y²
We need to simplify given complex fraction.
First we simplify numerator.
1/x y - 1/y²
= y² - xy / xy³
= y(y - x) / xy³
= y - x / xy²
Now we simplify denominator.
1/x²y - 1/x y²
= xy² - x²y / x³y³
= xy(y - x) / x³y³
= y - x / x²y²
So given fraction would be,
1/x y - 1/y² / 1/x²y - 1/x y²
= y - x / xy² / y - x / x²y²
= (y - x / xy²) × (x²y² / y - x )
= x²y² / xy²
= x
Therefore, the simplified form of given complex fraction is 1/x y - 1/y² / 1/x²y - 1/x y² = x
