Answer:

SO..........basically Order of operations are very easy. In a problem like this

(number 2) 25-14+3

The first thing you do would be to addition

The order of operation goes PEMDAS

P= parenthesis

E= Exponents

M= Mutpilcation

D= Divison

A=addition

S=Subtraction

so it would be 25-14+3

\ /

25-17

Then it would be 25-17

\ /

This is the answer to number 2 I hope it answers your question about the problem and what order of operation is

P.S How I remember PEMDAS is Please

Answer:

Order of operations is and order that you go by addition, subtraction, multiplication, division, exponentiation, and grouping.

Usually its just the first four because that's usually what you get in home work or assignments. If there is no addition you skip to multiplication and so forth. And the equation in parentheses usually goes first before you solve anything else. .

For example in your first question you would do addition first then subtraction. Since there is no multiplication or division you don't have to include that. 34 + 17 = 51 - 5 = 46

Se the FOIL method to evaluate the expression: (5+2)(4-5)

DaniilM [7]

The FOIL method is a method of expanding two given brackets by following the required steps. Thus using the FOIL method, the required answer is: -7

Expansion of brackets may be done using different methods, but these methods would give the same answer. Some methods that can be used are the binomial expansion method, FOIL method, etc.

The FOIL method is a shortened form of the steps required for the process. These required steps are First, Outside, Inside, and last.

Thus to expand the given brackets in the question, we have;

(5+2)(4-5) = 5(4 - 5) + 2(4 - 5)

= 20 - 25 + 8 - 10

= 28 - 35

(5+2)(4-5) = -7

Thus using the FOIL method, the answer to the question is -7.

Quick check: (5+2)(4-5) = (7)(-1)

= -7

Which one is equivalent what’s the work that goes with it? i’m very confused

Elenna [48]

Answer:

0.8r

Step-by-step explanation:

r - 0.2r

= 1r - 0.2r ← factor out r from each term

= r(1 - 0.2)

= r × 0.8

= 0.8r

Use technology or a z-score table to answer the question.

Drupady [299]

Answer:

Step-by-step explanation:

Finding the z-score:

z = (x - μ) / σ

z = (66 - 57) / 9

z = 1

Using a z-score table or calculator:

P(z < 1) = 0.8413

84.13% of 4000 is:

0.8413 (4000) = 3365.2

Rounding up to the nearest whole number, approximately 3366 students will score less than 66. Answer C.

A fence completely surrounds a pool,that is 30 feet by 10 feet.what is the approximate length,in feet,of the fence

tamaranim1 [39]

Because the fence's dimensions is 30 feet by 10 feet, you can assume that one side of the pool is 30 feet while the other, non-congruent side, is 10 feet. The formula for perimeter, which you are trying to find, is 2L+2W=P. In this problem, 30 will be your L and 10 will be your W. Therefore, 2(30) +2(10)=80.

So 80 feet will be your answer.

A biker travels 5 feet in 0.5 seconds. At this exact speed, how far will the biker travel in a minute?

Pavel [41]

A minute has 60 seconds, therefore we will deal with seconds now And since we have it that the biker travels 5 feet every 0.5 seconds, lets multiply that by 2 to get the traveled distance per second to make it easier 5*2=10 Finally, multiply 10 feet by 60 seconds(1 minute) = 600 feet
