Answer:

Since the length of the sides respects the Pythagorean theorem, these points form a right triangle.

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Right triangle:

Sum of the squares of the two smaller sides is equal to the square of the largest side(Pythagorean theorem).

Length of side PQ:

P (-2, -3), Q (4, 1)

[tex]a = \sqrt{(4 - (-2))^2+(1 - (-3))^2} = \sqrt{6^2 + 4^2} = \sqrt{52}[/tex]

Length of side PR:

P (-2, -3), R (2,4)

[tex]b = \sqrt{(2 - (-2))^2+(4 - (-3))^2} = \sqrt{4^2 + 7^2} = \sqrt{65}[/tex]

Length of side QR

Q (4, 1), R (2,4)

[tex]c = \sqrt{(2 - 4)^2+(4 - 1)^2} = \sqrt{2^2 + 3^2} = \sqrt{13}[/tex]

Pythagorean Theorem:

Smaller sides: a and c

Largest side: b

So

[tex]a^2 + c^2 = b^2[/tex]

[tex](\sqrt{52})^2 + (\sqrt{13})^2 = (\sqrt{65})^2[/tex]

[tex]52 + 13 = 65[/tex]

[tex]65 = 65[/tex]

Since the length of the sides respects the Pythagorean theorem, these points form a right triangle.

Answer: Statistics laws are true on average. Statistics are aggregates of facts, so a single observation is not a statistic. Statistics deal with groups and aggregates only.

Answer:

The simple interest that said investment yielded was 3.75% per year.

Step-by-step explanation:

Given that Sarah's current account balance is $ 2,600, and she made a single lump sum amount of $ 2,000 eight years ago into the account, to calculate the equivalent simple interest rate (quoted annually) that she earned the following calculation must be performed:

(2,600 - 2,000) / 8 = X

600/8 = X

75 = X

2,000 = 100

75 = X

75 x 100 / 2,000 = X

7,500 / 2,000 = X

3.75 = X

Thus, the simple interest that said investment yielded was 3.75% per year.

Answer:

Answer:

3/7 times 5/4

Step-by-step explanation:

when dividing fractions, all you do is keep the first fraction, change the sign to multiplication, and flip the last fraction. In this case it would be 3/7 and 5/4

Answer:

The answer is B: 3/7 times 5/4.

Step-by-step explanation:

The process is stay, change, flip.

Stay equals keep the first fraction the same (3/7).

Change equals change the operation (division to multiplication).

Flip equals flip the second fraction (flip 4/5 to 5/4).

Answer:

0

Step-by-step explanation:

f(x) = y

To find f(2), it means to find the value of y when x = 2.

From the graph, when x = 2, the corresponding y-coordinate = 0.

Therefore,

f(2) = 0

Answer:

Let L be the number of losses. T is the total number of games, and it has the value 64. W is the number of wins.

They won 28 more than they lost, so W = L + 28.

Since W = L + 28, W = 18 + 28 = 46.

Answer:

B

Step-by-step explanation:

The equations we need are:

(5(1/8) + 4(7/8) +6 = 16) to find the total weight of pasta, sauce, and onions.

(41/8) ÷ (1/2) = ? to find how many 1/2 pound servings Mariana can make.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

We have two types of fractions.

Proper fraction and improper fraction.

A proper fraction is a fraction whose numerator is less than the denominator.

An improper fraction is a fraction where the numerator is greater than the denominator.

Example:

1/2, 1/3 is a fraction.

3/6, 99/999 is a fraction.

1/4 is a fraction.

We have,

To find out how many 1/2-pound servings of pasta Mariana can make, we need to divide the total weight of pasta, sauce, and onions by 1/2.

Therefore, we need the equation:

(5(1/8) + 6 + 4(7/8)) ÷ (1/2) = ?

Simplifying the expression inside the parentheses, we get:

(41/8) ÷ (1/2) = ?

To divide by a fraction, we can multiply by its reciprocal. Therefore:

(41/8) ÷ (1/2) = (41/8) x (2/1) = 82/8 = 10(1/4)

So Mariana can make 10(1/4) servings of pasta.

Therefore,

The equations we need are:

(5(1/8) + 4(7/8) +6 = 16) to find the total weight of pasta, sauce, and onions.

(41/8) ÷ (1/2) = ? to find how many 1/2 pound servings Mariana can make.

Step-by-step explanation:

Given:

A figure of a right triangle.

To find:

The value of x and value of y.

Solution:

In a right angle triangle,

[tex]\sin \theta = \dfrac{Opposite}{Hypotenuse}[/tex]

[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]

In the given triangle,

[tex]\sin (60^\circ)=\dfrac{x}{6}[/tex]

[tex]\dfrac{\sqrt{3}}{2}=\dfrac{x}{6}[/tex]

[tex]\dfrac{\sqrt{3}}{2}\times 6=x[/tex]

[tex]3\sqrt{3}=x[/tex]

And,

[tex]\cos (60^\circ)=\dfrac{y}{6}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{6}[/tex]

[tex]\dfrac{1}{2}\times 6=y[/tex]

[tex]3=y[/tex]

Therefore, the value of x is [tex]3\sqrt{3}[/tex] and the value of y is 3.
