Evaluate: 20 - {3 × 8 - 5 - (3 - 25 ÷ 5)}

Answers

Answer:

Step-by-step explanation:

To evaluate the expression 20 - {3 × 8 - 5 - (3 - 25 ÷ 5)}, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right):

Inside the innermost parentheses, we have:

3 - 25 ÷ 5

= 3 - 5

= -2

Now, the expression becomes:

20 - {3 × 8 - 5 - (-2)}

Next, perform the multiplication and subtraction inside the innermost braces:

3 × 8 = 24

5 - (-2) = 5 + 2 = 7

The expression becomes:

20 - {24 - 7}

Continue inside the braces:

24 - 7 = 17

Now, the expression becomes:

20 - 17

Finally, subtract:

20 - 17 = 3

So, the value of the expression is 3.

Following the steps of the BODMAS rule, the expression simplifies to -1.

The question involves arithmetic operations such as subtraction, multiplication, and division. The correct order of these operations is dictated by the BODMAS rule, which stands for Brackets, Orders (powers and square roots, etc.), Division and Multiplication (left-to-right), Addition and Subtraction (left-to-right).

According to this rule, begin by calculating within the deepest set of brackets: 25 ÷ 5 = 5. Your expression now becomes: 20 - {3 × 8 - 5 - (3 - 5)}, which simplifies to 20 - {3 × 8 - 5 - -2}. The next step is to calculate the multiplication: 24 - 5 - -2, which further simplifies to 20 - {24 - 5 + 2}, which becomes 20 - {21}, leading to a final result of -1.

Jerome is writing a number in scientific notation. The number is greater than one million and less than ten million. What will be the exponent in the number Jerome writes?PLEASE HELP!!!!(by that i mean i want the answer)

Answers

The exponent in the number Jerome writes will be anywhere between 6 to 7.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Jerome is writing a number in scientific notation.

Let's suppose the number is x

The number x is greater than one million and less than ten million.

In scientific notation:

$\rm 10^6\leq x\leq 10^7$

We can say that from the above inequality that the exponent of the number will be between 6 to 7.

Thus, the exponent in the number Jerome writes will be anywhere between 6 to 7.

One million: 10^6

Ten million: 10^7

So the exponent will be anywhere between 6 and 7, inclusive

How to find the volume of a cylinder? Need help, thanks.

Answers

well I personally do not know the volume of a cylinder but for example if you had a cylinder that the radius(had of the diameter) was 5 and say the height was 13 then you could go on google, safari, etc. and search exactly this (also works with triangles, rectangles, squares, circles, parallelograms, trapezoids, etc. and also with the volume and surface area of triangular prisms, rectangular prisms, etc.) but any way type in this: what is the formula for the volume(area, Surface Area, etc.) of a cylinder(rectangular prism, triangular prism) you put in the height and the radius of the cylinder and the answer will automatically pop up if this didn't help(which I really hope it did!!) the I am terribly sorry
