Answer 1

Answer:

the order of operations tells us how to solve a problem.

first is P for parentheses. this means you solve all the expressions within the parentheses. this ensures a simplified expression before moving on.

second is E for exponents. this means you solve all the expressions with exponents. by doing this before MDAS, you do not raise the wrong values.

third and fourth is M/D for multiplication/division. the / is between these two because these steps are interchangeable. you can multiply or divide first. the results will be the same.

this also applies to the fifth and sixth, which are A/S for addition/subtraction.

if f(x)=2x-1 and g(x)=x^2-3x-2, find (f+g)(x)

Answers

Answer: (f+g)(x)=x²-x-3

Step-by-step explanation:

(f+g)(x) means f(x)+g(x). Since we are given f(x) and g(x), we can add them together.

(f+g)(x)=2x-1+x²-3x-2                [combine like terms]

(f+g)(x)=x²-x-3

Now, we know that (f+g)(x)=x²-x-3.

What property is 6m*1=6m

The property is Multiplicative identity,

what is Multiplicative identity?

An identity element (such as 1 in the group of rational numbers without 0) that in a given mathematical system leaves unchanged any element by which it is multiplied.

Given:

6m*1=6m

As, It states that if a number is multiplied by 1 the resultant will be the number itself. “1” is the multiplicative identity of a number. It is represented as p × 1 = p = 1 × p. Let us understand the relation with help of a real number example.

Here let say p = -3. Putting the value of p in p × 1 = p = 1 × p, we get

−3 × 1 = −3.

So, if 6m is multiplied by 1 it gives 6m using multiplicative identity.

Which equation is equivalent to x+5=12

Answers

Answer:

Step-by-step explanation:

Solve 20 - x/3 = x/2 , put the number only in the box.

Answers

Answer:

x = 24

Step-by-step explanation:

[tex]20 - \frac{x}{3} = \frac{x}{2} [/tex]

Multiply through by the LCM that's 6 in order to eliminate the fraction

That's

[tex]6 \times 20 - 6 \times \frac{x}{3} = 6 \times \frac{x}{2} \\ 120 - 2x = 3x[/tex]

Using the addition property add 2x to both sides of the equation

That's

[tex]3x + 2x = 120 + 2x - 2x \\ 5x = 120[/tex]

Divide both sides by 5

[tex] \frac{5x}{5} = \frac{120}{5} [/tex]

The measure of an angle is 89 times the measure of its supplementary angle. What is the measure of each angle

Answers

Answer:

2 and 178

Step-by-step explanation:

If we take an instance of a number 'x', according to the question we find that x+x*89=180(Because they are complementary)

We get, = 89x+x=180

=> 90x=180

=> x=180/90

=> x =2

So, we found that x=2 , hence the other angle is going to be 2*89=178

This is correct as 2+178=180(as they are supplementary to each other)

Equivalent rates can be used to compare different sets of quantities that have the same value. A rate that compares a quantity to one is called a unit rate. The unit rate has a denominator equal to one when written as a fraction. Unit rates can be used to find larger equivalent rates.

To convert measurements in the metric system, you can move the decimal point left or right. Why does this work? The metric system only uses decimal numbers. Converting in the metric system does not involve multiplication or division. The metric system is based on powers of 10. The metric system does not have conversion factors.​

Answers

Answer:

x=20°

Step-by-step explanation:

This is actually simpler than it seems. Try redrawing (or maybe just imagine) that the only inscribed angle is x with the two lines going to the 40°. If we let 40°=θ, then: x=θ/2

This is actually true for any situation with inscribed angles, so you could use this to find w, y, and z as well.

Anyways x=(40°)/2=20°, so x=20°

Probenecid is a drug used by some athletes to prevent the excretion of other substances into urine, thus lowering their detectable concentrations. A scientist makes three measurements of a urine sample known to contain probenecid and obtains a confidence interval of 11.8±0.5 mg/L at the 95% confidence level. What would happen to the confidence interval at the same confidence level if the number of measurements is increased to 10 assuming the standard deviation remains the same?

Answers

Answer:

The confidence interval will decrease

Step-by-step explanation:

Generally the confidence interval is mathematically represented as

[tex]\= x \pm z_c * \frac{s}{\sqrt{n} }[/tex]

Here [tex]z_c[/tex] is called the critical value of [tex]\frac{level \ of \ significance }{2}[/tex] obtained from the normal distribution table , s is the standard deviation , n is the sample size (number of measurements )

Now looking at the formula we that if the increase the sample size that the confidence level would decrease

So if the n is increased to 10  

   The  confidence interval would decrease

Late payments remain on a credit report for up to seven years from the original delinquency date -- the date of the missed payment.

Bankruptcy public records stay on your Equifax credit report from seven to 10 years, depending on the type of bankruptcy.

Other negative accounts, such as repossessions, can also stay on your report for up to seven years from the date of the first missed payment that led to the negative status.

Hence The most likely number of years that this negative information will remain on their credit reports will be 7 to 10 years.

A local business does $1200 in sales on Monday and $1400 dollars in sales on Tuesday.
Which of the following a correct sentence to describe the ratio of Monday to Tuesday?

Answers

$1200+ $1400 = 2600


Answer:
1200 : 1400 = 6 : 7


The ratio is not in lowest terms so we found an equivalent ratio by simplifying.
Solution:

We can simplify the ratio 1200 : 1400 by dividing both terms by the greatest common factor (GCF).

The GCF of 1200 and 1400 is 200.

Divide both terms by 200.
1200 ÷ 200 = 6
1400 ÷ 200 = 7

Therefore:
1200 : 1400 = 6 : 7

A fence on a hill uses vertical posts L and M to hold parallel rails N and P. If m∠1 = 115, then what is the measure of ∠16?

Answers

Step-by-step explanation:

Given information:

A fence on a hill uses vertical posts L and M to hold parallel rails N and P

The diagram is attached below

Here lines N  and P are parallel lines

Transversal line for parallel lines N  and P is line L

Calculation:

angle 1  and angle 16 are consecutive exterior angles

If parallel lines are cut by a transversal then consecutive exterior angles are supplementary

[tex]<1 +<16=180\\115+<16=180\\<16 = 180-115\\<16=65[/tex]

So measurement of angle 16 = 65 degrees
