LAST ATTEMPT IM MARKING AS BRAINLIEST!! ( Pythagorean theorem )

The probability of a student taking a math class and a physics class is \(\frac{7}{15}\).

What is probability?

To determine the possibility of an event, one might utilise probability as a technique. Only the probability of an event occurring can be determined using it. A scale where 1 denotes a specific occurrence and 0 signifies impossibility.

We are given that the probability of the student taking a physics class is \(\frac{2}{3}\).

Also, it is given that the probability of a student taking a math class given that the student takes a physics class is \(\frac{7}{10}\).

So, probability of a student taking a math class and a physics class is:

⇒ Probability =  \(\frac{2}{3}\) *  \(\frac{7}{10}\)

⇒ Probability = \(\frac{14}{30}\)

⇒ Probability = \(\frac{7}{15}\)

Hence, the probability of a student taking a math class and a physics class is  \(\frac{7}{15}\).

The value of 12x in the expression is 10

You multiply 5 = 6x  by 2 to get 12x

From the question, we have the following parameters that can be used in our computation:

2x + 5 = 8x

You subtract 2X from each side to get

5 = 6x

Then multiply both sides by 2

This gives

10 = 12x

So, we have

12x = 10

Why do you multiply both sides by 2

You multiply by 2 because the question requests for the value of 12x

Since, we have solved for 6x, the next step is to multiply 6x by 2 to get 12x

i.e. 6x * 2 = 12x

Answer:

A. $10.56

Step-by-step explanation:

Edge 2020

Jamie saved $10.56 by buying the book on sale and using the coupon.

The Percentage is a relative value that indicates the hundredth parts of any quantity.

Given that, in sale books are being sold at 20% off, Jamie has extra 15% coupon, Jamie buys a hardcover fiction book that is priced $32.99, we need to determine how much she saved.

So,

32.99 × 80/100 × 85/100

= $22.43

Therefore, the books costs Jamie = $22.43

The amount she saved = 32.99 - 22.43 = $10.56

Hence, Jamie saved $10.56 by buying the book on sale and using the coupon.

Each expression should be matched with its simplified form as follows;

P(x) · Q(x)  ⇒  \(\frac{12}{(3x - 1)(-3x+2)}\)

P(x) ÷ Q(x)  ⇒  \(\frac{-3x+2}{3(3x - 1)}\)

In Mathematics and Geometry, a function is a mathematical equation which defines and represents the relationship that exists between two or more variables such as an ordered pair in tables or relations.

Next, we would determine the corresponding composite function of P(x) and Q(x) under the given mathematical operations (multiplication and division) in simplified form as follows;

P(x) · Q(x) = \(\frac{2}{3x - 1} \cdot \frac{6}{-3x+2}\)

P(x) · Q(x) = \(\frac{2}{3x - 1} \times \frac{6}{-3x+2}\)

P(x) · Q(x) = \(\frac{12}{(3x - 1)(-3x+2)}\)

P(x) ÷ Q(x) = \(\frac{2}{3x - 1} \div \frac{6}{-3x+2}\)

P(x) ÷ Q(x) = \(\frac{2}{3x - 1} \times \frac{-3x+2}{6}\)

The number of chair covers Diane will be able to make is 5.

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

Example: 1/2, 1/3 is a fraction.

We have,

Length of the fabric = 20 yards

Length of fabric needed for each chair cover = 3(2/5) yards

The number of chair covers that can be made with 20 yards.

= 20 ÷ 3(2/5)

= 20 ÷ 17/5

= 20 x 5/17

The new water bill after 5% increase is $126.

The ratio that may be stated as a fraction of 100 is called as a percentage in mathematics. To compute a percentage of a number, divide it by its whole and then multiply it by 100. The percentage therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given bill of water =$120

Increment in percentage=5%

New water bill= 120+120×5/100

=$126

Hence, The new water bill after 5% increase is $126.

% increase = Increase in bill ÷ Old bill × 100.

5%=Increase in bill/120×100

Increase=5×120/100

=6

New bill=Old bill+ increase=120+6=126

hence, the new water bill after 5% increase is $126.

Step-by-step explanation:

Answer: each base angle in an isosceles right triangle measures 45 degrees.

Step-by-step explanation:

In an isosceles right triangle, two sides have equal lengths, and one angle is a right angle (90 degrees).

Since it is an isosceles triangle, the two base angles (the angles opposite the equal sides) must be congruent, meaning they have the same measure.

To find the measure of each base angle, we can use the fact that the sum of the angles in a triangle is 180 degrees.

Let's denote the measure of each base angle as "x". Then, the sum of the three angles in the triangle can be expressed as:

x + x + 90 = 180

Simplifying the equation:

2x + 90 = 180

Subtracting 90 from both sides:

2x = 90

Dividing both sides by 2:

x = 45

16 is the number which is one-fifth of a number when one-fourth of that same number is 20.

As per the given data:

One-fourth of the number is resulted to 20.

Here we have to determine the result of one-fifth of the same number from the given options.

An expression for a portion of a whole is a fraction.

For any real numbers, the fractional component of x is defined.

Let the number be X.

One-fourth of a number is 20 which means:

Multiply the one-fourth fraction with an unknown number which results in the number 20.

\($\frac{1}{4}\)  (X) = 20

X = 20 × 4

X = 80

Now we have to determine that one-fifth of the same number.

Multiply the one-fifth fraction by 80.

We get:

= \($\frac{1}{5}\) (80)

= \($\frac{1}{5}\)   × 5 × 16

= 16

One-fifth of the number 80 is 16

Therefore Option (D) - 16 is the correct answer.
