To find the percent of a discount, ______________. A. find the percent of decrease from the original price to the new price. B. find the percent of increase from the new price to the original price. C. multiply the original price by the new price. D. divide the new price by the original price.

The correct and best answer would be letter B. To find the percent of a discount, you have to find or solve for the percent of increase from the new price to the original price. This is because you usually have the new price being given to you so you compare it with the old price to know the percent discount.

(2.03) The table shows the solution to the equation |2x − 3| − 1 = 2: Step 1 |2x − 3| = 2 + 1 Step 2 |2x − 3| = 3 Step 3 2x − 3 = 3 or 2x + 3 = 3 Step 4 2x = 6 or 2x = 0 Step 5 x = 3 or x = 0 Which is the first incorrect step? (1 point)

The first incorrect step would be step number three since when solving Absolute-Value Equations, when you isolate the Absolute-Value bars and the terms inside of it, the next step should be to make two equations: one that equals the original number given on the right side of the equal sign and one that is the opposite of the number on the equal sign. For example, in this case, Step three should have turned out more like this:

|2x - 3| = 3

2x - 3 = 3 AND  2x - 3 = -3

Two beauticians, Lydia and Jackie, are working on your hair. Lydia can complete the work in 2 hours, while Jackie can complete the work in 1 hour. How many hours do the beauticians take if they work together? A. one half B.three halvess C.two thirds D.four thirds

Answer:

Option C.

Step-by-step explanation:

Two beauticians Lydia and Jackie are working on your hair.

Lydia takes the time to complete the work = 2 hours

Per hour work done by Lydia = 1/2

Jackie complete the  work = 1 hour

In one hour total work done by both Jackie and Lydia together = 1+\frac{1}{2}=1\frac{1}{2}or \frac{3}{2}

therefore, time taken by both to complete the work will be = \frac{1}{\frac{3}{2} } = \frac{2}{3}

Option C. two thirds is the correct option.

QUESTION POSTED AT 22/01/2020 - 01:22 AM

One spinner is divided into five equal sections numbered 1 to 5. A second spinner is divided into seven equal sections numbered 6 to 12. How many total outcomes are there if both spinners are spun?

Answer: Hence, there are 35 outcomes in total if both the spinners are spun.

Step-by-step explanation:

Since we have given that

Number of outcomes for spinner numbered 1 to 5 = 5

Number of outcomes for spinner numbered 6 to 12 = 7

So, Using the Fundamental theorem of Counting, we get the total number of outcomes when both the spinners are spun together.

So, Number of total outcomes would be

7\times 5\\\\=35

Hence, there are 35 outcomes in total if both the spinners are spun.

QUESTION POSTED AT 22/01/2020 - 01:12 AM

Given: m∠AEB = 45° ∠AEC is a right angle. Prove: bisects ∠AEC. Proof: We are given that m∠AEB = 45° and ∠AEC is a right angle. The measure of ∠AEC is 90° by the definition of a right angle. Applying the gives m∠AEB + m∠BEC = m∠AEC. Applying the substitution property gives 45° + m∠BEC = 90°. The subtraction property can be used to find m∠BEC = 45°, so ∠BEC ≅ ∠AEB because they have the same measure. Since divides ∠AEC into two congruent angles, it is the angle bisector.

Answer:

The proof is explained below.

Step-by-step explanation:

Given ∠AEB=45° and also ∠AEC is right angle i.e ∠AEC=90°

we have to prove that EB is the angle bisector.

In the right angled triangle AEC,

∠AEC=90° and also ∠AEB=45°

∵ ∠AEB+∠BEC=∠AEC

⇒ 45° + ∠BEC = 90°

By subtraction property of equality

∠BEC = 45°

Hence,  ∠AEB = ∠BEC = 45°

The angle ∠AEB equally divides by the line segment EB therefore, the line segment EB is the angle bisector of angle ∠AEB.

If a work group consistently achieves 80 % of its quarterly goals and the work group generally has 25 objectives per quarter how many objectives can the work group be expected to achieve in any given quarter?

To determine the number of goals the group achieve in a given quarter (q), multiply the total goals they generally have (n) by their percent success (r)
                             q = n x r
Substituting the given,
                            q = (25 objectives) x 0.80 = 20
Thus, the group is expected to achieve 20 goals.

Harriet is cultivating a strain of bacteria in a petri dish. Currently, she has 103 bacteria in the dish. The bacteria divide every two hours such that the number of bacteria has doubled by the end of every second hour. How many bacteria will Harriet have in the dish at the end of 6 hours

Formula for growth or decay

R= R_{0}[1 \pm \frac{r}{100}]^t

R= Final population of Bacteria

R_{0}= Initial Population

r = Rate of growth or decay

t= Time period

R_{0}= 103 bacteria

when, t=2

R becomes 103 × 2= 206 bacteria

Substituting these values in the formula of growth

206 = 103 × (1+ \frac{r}{100})^2

Dividing both sides by 103, we get

2 = (1+ \frac{r}{100})^2

(1+ \frac{r}{100})= √2------(1)

(1+ \frac{r}{100})= 1.414

r = (1.414 -1) × 100= .414 × 100= 41.4%

Number of bacteria at the end of 6 hours = 103 × (1+ \frac{r}{100})^6= 103 × [\sqrt{2}]^6 ------Using (1)

= 103 × 2³

=103 × 8

= 824→→bacteria that Harriet have in the dish at the end of 6 hours

Juliana has created the function f(x) = the quantity of 3x plus 2, divided by 4 to represent the cost of texting on her current plan, where x represents the number of texts. Juliana discovers that, using the inverse function to solve for x = 24, she can predict how many texts she can use for $24

Let

x-------> the number of texts

f(x)------> the cost of texting on Juliana's current plan

we know that

 f(x) = (3x+2)/4

Step  1

Find the inverse function of f(x)

 f(x) = (3x+2)/4

Let

y=f(x)

 y = (3x+2)/4

exchange the variables x for y and  y for x

 x = (3y+2)/4

Clear variable y

x= (3y+2)/4\\ 4x= 3y+2\\ 3y=4x-2\\ y=(4x-2)/3

Let

 f(x)^{-1}=y

 f(x)^{-1}=(4x-2)/3 ------> this is the inverse function

where

x ------> represent the cost

f(x)^{-1}------> the number of texts

Solve for  x=\$24

substitute

 f(x)^{-1}=(4x-2)/3

 f(x)^{-1}=(4*24-2)/3

 f(x)^{-1}=31.33

therefore

the answer is

 31\ texts

QUESTION POSTED AT 22/01/2020 - 12:36 AM

If you multiply a number by 3 and divide by 4 the result is 24. what is the number?

To solve this problem, we are going to set up an equation.  Let the number that we are trying to find be represented by the variable x.  If we plug in the numbers that we know, we get the following equation:

3x/4 = 24

To simplify this equation, we need to multiply both sides by 4, to begin getting the x alone on the left side of the equation.

3x = 96

Finally, we need to divide both sides by 3, to get rid of the coefficient that is being multiplied to x.

x = 32

Therefore, the number that you are trying to find is 32.

For the equation y = 2x2 − 5x + 18, choose the correct application of the quadratic formula. x equals negative five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two x equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two x equals negative two plus or minus the square root of two squared minus four times negative five times eighteen, all divided by two times negative five x equals two plus or minus the square root of two squared minus four times negative five times eighteen, all divided by two times negative five

Answer:

Option 2nd is correct

x equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two

Step-by-step explanation:

Given the equation:

y = 2x^2-5x+18

Use the quadratic formula:

A quadratic equation y = ax^2+bx+c.............[1], then the solution is given by:

x = \frac{-b \pm \sqrt{b^2-4ac}}{2a}

On comparing given equation with [1]

a = 2 , b = -5 and c = 18

then;

x = \frac{-(-5) \pm \sqrt{(-5)^2-4(2)(18)}}{2(2)}

x = \frac{5 \pm \sqrt{(-5)^2-4(2)(18)}}{2(2)}

Therefore, the correct application of the quadratic formula is,

x equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two
