It is a rectangle, TUVW. A parallelogram has diagonals that are perpendicular and angles that are all 90 degrees.
Is a parallelogram ever a rectangle?No, a parallelogram is not always a rectangle. In a rectangle, all angles must be equal to 90°. But for a parallelogram, no angles need to be equal to 90°. In a rectangle the diagonals are equal but in a parallelogram, diagonals are not equal.
Parallelogram has opposite sides equal and parallel. Rectangle also has opposite sides equal and parallel. The difference between the two is that sides of rectangles form 90 degree while that of parallelogram don't.
A square is a parallelogram. This is always true. Squares are quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Parallelograms are quadrilaterals with two sets of parallel sides.

Mr. Robinson, the owner of two car dealerships in Clarksville, is holding a contest to see which one can sell the most cars. Clarksville Cars has already sold 15 cars, and Robinson's Autos has sold 13 cars. Going forward, the salespeople at Clarksville Cars think they can sell 8 cars per day, whereas the salespeople at Robinson's Autos are aiming for sales of 10 cars per day. If the salespeople's predictions are accurate, it won't be long before the two dealerships are tied. How many cars will each lot have sold? How long will that take?
The dealerships will each have sold
cars in
days.
Answers
The dealerships will each have sold 23 cars in 1 day.
How many cars would the dealerships sell when they are tied?The first step is to form a linear equation that represents the number of cars that are sold by the dealerships. A linear equation is an equation that has a single variable that is raised to the power of one.
The form of a linear equation that represents the total cars sold by the dealership is:
Total cars sold = cars already sold + (number of cars sold per day x number of days)
Total cars sold by Clarksville Cars= 15 + (8 x d)
= 15 + 8d
Total cars sold by Robinson's Autos = 13 + (10 x d)
= 13 + 10d
When the two dealerships are tied, the two above functions would be equal:
13 + 10d= 15 + 8d
In order to determine the value of d, take the following steps:
Combine and add similar terms:
10d - 8d = 15 - 13
2d = 2
Divide both sides of the equation by 2
d = 2 / 2
w = 1 week
Number of cars that would have been sold by each dealership =
13 + 10(1)
13 + 10 = 23 cars

(Hint: Use the conversion factor 1 mile height h 5280 ft.) A person can see a distance of approximately miles on a clear day from a height of 1461 feet above the given planet. (Round to the nearest tenth as needed.)
Answers
A person can see a distance of approximately 32.9 miles on a clear day from a height of 1461 feet above the given planet.
d = 2 √(hR)
We can use the formula d = 2 √(hR) to calculate the distance d to the horizon that a person can see on a clear day from a 1461 feet above the given planet.
First, we need to convert the height of 1461 feet to miles. We can use the conversion factor of 1 mile = 5280 feet. Therefore, the height h = 1461/5280 ≈ 0.2772 miles.
Next, we need to find the radius of the planet. The radius of the planet is given as 3900 miles.
Finally, we can substitute h = 0.2772 miles and R = 3900 miles into the formula d = 2 √(hR).
d = 2 √(0.2772*3900) = 2 √(1083.08) ≈ 32.9 miles
Therefore, a person can see a distance of approximately 32.9 miles on a clear day from a height of 1461 feet above the given planet.

What is the Linear equation?
An algebraic equation with only a constant and a first-order (linear) term is said to be linear if it has the formula y = mx + b, where m is the slope and b is the y-intercept. The above is occasionally referred to as a "linear equation with two variables," where y and x are the variables.
y = mx + c
where m denotes the slope.
The y-intercept is represented by the constant c. (Where x is zero)
In our instance, y-intercept equals 60.
The line's equation will therefore be:
y = mx + 60
y = mx + 60
There are given the line's coordinates (4, 90). These considerations will thus satisfy the equation.
90 = 4*m + 60
4.m = 30 m = 7.5 m = 7.5 y = 7.5x + 60 y = 7.5 * 6 + 60 y = 45 + 60 y = 105 is
y = 7.5x + 60.
If Adam's study for 6 hours then his score would be
y = 7.5x + 60.

the probability of rolling an even number on an unfair die is 0.65 which of the following is closest to the probability that an even number
Answers
The probability of rolling an even number on an unfair die is 0.65, which means that if you roll the die multiple times, the proportion of times that you roll an even number will be close to 0.65.
So, the probability of rolling an even number is closest to option c) 0.65
A die is a cube with numbers on each face that are used in games or gambling. A fair die is a die that is equally likely to land on any of its faces, meaning that each face has a probability of 1/6 of being the face that lands up. An unfair die is a die that does not have an equal probability of landing on each face. It means that the probability of landing on each face is not the same.
In the given scenario, it is said that the probability of rolling an even number on an unfair die is 0.65. This means that if you roll the die multiple times, the proportion of times that you roll an even number will be close to 0.65. It means that the die is not fair, and it is more likely to roll an even number.

A machinist must cut 12 strips of metal that are each 2 ft 6 7/8 in. long. What is the total length needed in inches?
Answers
The total length of the metal strips needed in inches is 370.5 inches
How to convert feet to inches?Number of strip metals = 12
Length of each strip metal = 2 ft 6 7/8 in.
Convert feet to inches:
1 feet = 12 inches
2 feet = 24 inches
2 ft 6 7/8 in = 30 7/8 inches
Total length of strip metals= Number of strip metals × Length of each strip metal
= 12 × 30 7/8 inches
= 12 × 247/8
= 2,964/8
= 370.5 inches
So therefore, the total length of the metal strips is 370.5 inches

which of these events are mutually exclusive if you roll a pair of dice?i. a: at least one die is a 3ii. b: at least one die is a 6iii. c: the sum is 11
Answers
When rolling a pair of dice, there are 36 possible outcomes, each representing a unique combination of the numbers on the two dice.
Event A: "at least one die is a 3" is not mutually exclusive with Event B: "at least one die is a 6" or Event C: "the sum is 11"
Event A and Event B are mutually exclusive because when one of the die is a 6, the other die cannot be a 3 and vice versa.
Event A and Event C are not mutually exclusive because there are some outcomes where at least one die is a 3 and the sum is 11. For example (3,8), (4,7) and (6,5) are all outcomes where at least one die is 3 and the sum is 11.
Event B and Event C are not mutually exclusive because there are outcomes where at least one die is a 6 and the sum is 11. For example (5,6) and (6,5) are both outcomes where at least one die is a 6 and the sum is 11.
So, in conclusion, Event A and Event B are mutually exclusive, but Event A and Event C and Event B and Event C are not mutually exclusive.

The probability that the first item is not the first to be delivered is 0.6667
How to determine the probabilityLet's call the events that the first, second, and third items arrive on the first day of February A, B, and C, respectively.
The probability that the first item arrives on the first day of February is 1/3. The probability that the second item arrives on the first day of February is 1/3, The probability that the third item arrives on the first day of February is 0.Therefore, the probability that one of the other two items arrives first is
1/3 + 1/3 = 2/3.
The probability that the first item is not the first to be delivered is
1 - 2/3 = 1/3

convert 47 in^2 into square centimeters?
Answers
47 square centimeters is equal to 303.225 square inches.
How is cm2 converted from cm?
Measure the length and width of an object, such as a rectangle, and multiply the results to get the number in square centimeters. In the event that the length and width are 15 cm and 10 cm, respectively, the formula is 15 cm*10 cm, which equals 150 cm2.
Any number that is multiplied by itself is transformed into a square. A different word for this is a number squared. The symbol for "squared" is 22 since 2 x 2 equals 4.
In mathematics, the squared sign (2), an arithmetic operator, stands in for multiplying an integer by itself. The "square" of an integer is the sum of that number and itself. Therefore, 10,000 square meters are represented by one square centimeter.
1 square inch = 6.4516 square centimeters.
47 in^2 = 47 × 6.4516
