A computer desk, originally priced at $83, is now on sale for $78.85

originally priced at $83. After discount the price becomes $78.85

Discount amount =  $83 - $78.85 = $4.15

Decrease rate = discount amount divide by original price

Decrease rate = [tex]\frac{4.15}{83}= 0.05[/tex]

Decrease rate = 0.05

To find percent of decrease we multiply by 100

0.05 * 100 = 5%

Decrease percentage = 5%

y - 4 = - [tex]\frac{5}{7}[/tex](x + 3 )

the equation of a line in point-slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

to calculate m use the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (4, - 1) and (x₂, y₂ ) = (- 3, 4)

m = [tex]\frac{4+1}{-3-4}[/tex] = [tex]\frac{5}{-7}[/tex] = - [tex]\frac{5}{7}[/tex]

use either of the 2 points as a point on the line

To evaluate the expression (5/2)^2 + 3^3/4, we simplify each part separately, then add the results. The final value of the expression is 13.

To evaluate the expression (5/2)^2 + 3^3/4, we'll start by simplifying each part separately.

The first part, (5/2)^2, means we raise 5/2 to the power of 2. To do that, we multiply the numerator and denominator of 5/2 by itself:

(5/2)^2 = (5/2) x (5/2) = 25/4.

The second part, 3^3/4, means we raise 3 to the power of 3, and divide the result by 4:

3^3/4 = 27/4.

Now we can add the two simplified parts together:

(5/2)^2 + 3^3/4 = 25/4 + 27/4 = 52/4 = 13.

I'd start with setting up the equations. Calling x the number of students in most popular country 1, and y in country 2.

x + y = 44740

x - y = 5672

now solve for x1 and x2. You can subtract second from first:

0 + 2y = 39068

y = 19534

so

x = 5672 + 19534 = 25206

Add a sentence to answer it in words.

total students= 44740 divided by 2 countries= 22370 for each country. if were trying to get a difference of 5672 students, then were gonna divide that 5672 by 2 which is gonna = 2836 students. country 1= 22370 students + 2836 of country 2's students. country 2 is 22370 students - 2836 students that we gave to country 1. so now, country 1 ends up with 25206 students, country 2 end up with 19534 students. a difference of 5672.

in mathematics the product of numbers means multiply the numbers

let x be the number, then the product of x and 3 = 3x

the result of this multiplication is 87

so 3x = 87 is the equation to solve the problem

the solution is x = 29

The equation used to solve this problem is 3x = 87. The solution, found by isolating x, is 29.

The equation that could be used to solve the problem 'The product of a number and 3 is 87. What is the number?' is 3x = 87. This equation represents 'the product of a number (x) and 3 equals 87'. You would solve this by dividing both sides by 3 to isolate x, resulting in the solution x = 29. Thus, the number that when multiplied by 3 equals 87 is 29.

Answer:

(0, -3)

Step-by-step explanation:

The terminal ray of the angle with measure 3π/2 radians is the negative y-axis. The point that is 3 units from the origin on that ray has x-coordinate 0 and y-coordinate -3. The point is (0, -3).

The length of the three sides of the triangle is 17cm, 25cm, and 12cm.

To solve this problem, let's assign variables to the three sides of the triangle. Let x represent the shortest side, (x + 8) represent the longest side, and (x - 5) represent the third side.

Using the perimeter given, we can set up an equation:

x + (x + 8) + (x - 5) = 56

Simplifying the equation, we have 3x + 3 = 56, then 3x = 53, and finally x = 17.

Therefore, the three sides of the triangle are:
Shortest side: 17cm
Longest side: 17 + 8 = 25cm
Third side: 17 - 5 = 12cm

Step-by-step explanation:

let X be the random variable for number of times the clock fails .

X is Poisson with average = 6.8% = 0.0068

PDF of x = e^(-0.0068) 0.0068^x/x!

a) The probability that the​ student's alarm clock will not work on the morning of an important final​ exam = P(X=0) = 0.00675

b) If the student has two such alarm​ clocks,  the probability that they both fail on the morning of an important final​ exam:

Since both clocks are  independent prob for both failing is

P(x1 fails) *P(x2 fails) = 0.00675(0.00675) = 0.000455625

c) the probability of not being awakened if the student uses three independent alarm​ clocks = Prob for all 3 fails = 0.00675^3

= 0.00000307546

d) Yes. Because all three fail probability is almost zero.

D. ​Yes, because you can always be certain that at least one alarm clock will work.

a ratio of 5 : 5 simplifies to 1 : 1, which basically means we require the midpoint of the line segment

using the midpoint formula

M = [[tex]\frac{1}{2}[/tex] (0 + 20 ), [tex]\frac{1}{2}[/tex] (15 + 0)] = (10, 7.5 )

Answer:

Option C). (10, 7.5)

Step-by-step explanation:

We have to find the coordinates of point M that divides the segment AB into a ratio of 5:5.

Vertices A and B are (0, 15) and (20, 0)

Ratio 5:5 is simply the ratio 1:1 means point M is the midpoint of segment AB.

So x-coordinate of M will be [tex]\frac{(20+0)}{2}=10[/tex]

and y - coordinate will be = [tex]\frac{(15+0)}{2}=7.5[/tex]

Therefore Option C. (10, 7.5) are the coordinates of point M.

Answer:

Total time of the concert  = 59.5 min =  59 minute 30 seconds

Explanation:

 At a school concert the orchestra plays 8 songs that are 4.25 min and 3 songs that are twice as long as each of the others.

 Total length of 8 songs = 4.25*8 = 34 min

 Length of 3 songs = 2*4.25 = 8.5 min

 Total length of 3 songs = 3* 8.5 = 25.5 min

Total time of the concert = 34 + 25.5 = 59.5 min =  59 minute 30 seconds

The concert is 59.5 minutes long: 8 shorter songs at 4.25 min each and 3 longer songs at 8.5 min each.

To find the total duration of the concert, we first calculate the duration of the 8 shorter songs and then the longer ones.

1. Shorter songs:

Duration of each shorter song = 4.25 minutes

Total duration of 8 shorter songs = 8 × 4.25 = 34 minutes

2. Longer songs:

Each longer song is twice as long as the shorter ones, so its duration is 2 × 4.25 = 8.5 minutes

Total duration of 3 longer songs = 3 × 8.5 = 25.5 minutes

Now, add the durations of both types of songs to find the total duration of the concert:

Total duration = Duration of shorter songs + Duration of longer songs

Total duration = 34 minutes + 25.5 minutes = 59.5 minutes

So, the concert is 59.5 minutes long.

The product of (3 + 2i) and a complex number is (17 + 7i)

The product of (3 + 2i) and a complex number is (17 + 7i).

Let the complex number be a + ib

Product means we multiply

So (3+2i) * (a + ib) = (17+7i)

WE need to find a+ ib

Divie by 3 + 2i on both sides

a + ib = (17+7i) / (3+2i)

To divide multiply by the conjugate (3-2i)

[tex]a + ib = (\frac{ 17+7i)*(3-2i)}{(3+2i)(3-2i)}[/tex]

[tex]a + ib = (\frac{(17*3+7*2)+(7*3-17*2)i}{3^2-2^2}[/tex]

[tex]a + ib = (\frac{(65)+(-13)i}{13}[/tex]

[tex]a+ib = \frac{65}{13} - \frac{13}{13}[/tex]

a+ib = 5 - i

The required complex number is 5 - i

Answer:

37+55i

Step-by-step explanation:

The product of (3 + 2i) and a complex number is (17 + 7i) is expressed as shown below:

(3+2i)(17+7i)

Expanding the bracket,

= 51+21i+34i+14i²

= 51+55i+14i²

Note that in complex numbers i² = -1

Substituting this into the result, we have:

= 51+55i+14(-1)

= 51+55i-14

= 37+55i

The product of both complex number is 37+55i

Answer:

x = 28°

Step-by-step explanation:

∠AOD and ∠BOC are vertical angles, hence congruent. That means the sum of ∠COE, ∠EOF, and ∠FOB is ∠BOC.

... 3x +x +(x+12°) = 152°

... 5x = 140° . . . . collect terms, subtract 12°

... x = 28° . . . . . . divide by 5

If line AB and CD are parallel to each other, hence the value of x from the given diagram is 39.2

To find the value of x from the given diagram, we will have to use the formula for finding the angle at a point.

152 + 3x + x + x + 12 = 360

152 + 12 + 5x = 360

164 + 5x = 360

5x = 360 -164

5x = 196

x = 196/5

x = 39.2

Hence the value of x from the given diagram is 39.2

To find the number of 30-day periods until the value of the gift cards will be equal, we set up and solve an equation. The value of each card will be $10 when they have equal value.

To solve this problem, we can set up an equation to represent the value of each gift card over time and find when they will be equal.

Let x be the number of 30-day periods that have passed. After x periods, the value of the first gift card will be $50 - $2x, and the value of the second gift card will be $40 - $1.50x.

Setting the two expressions equal, we get:

$50 - $2x = $40 - $1.50x

Simplifying the equation, we have:

$10 = $0.5x

Dividing both sides by $0.5, we get:

x = 20

So, after 20 periods (or 20 months), the value of each gift card will be equal.

To find the value of each card at that point, we can substitute x = 20 into one of the expressions. Let's use the first gift card:

Value = $50 - $2(20) = $50 - $40 = $10

Therefore, when they have equal value, each gift card will be worth $10.

There are four (4) whole-number solutions to these inequalities:

... {(4, 1), (5, 0), (6, 0), (7, 0)}

Step-by-step explanation:

These are nicely solved by graphing. Whole numbers are non-negative integers, so x and y can be any values 0, 1, 2, .... The area of overlap on the graph clearly shows that y=0 and y=1 are the only viable choices for y, and that the values for x are limited in each of these cases.

For this case we have the following equation:

[tex](2x + 3) ^ 2 + 8 (2x + 3) + 11 = 0[/tex]

Let [tex]u = 2x + 3[/tex]

We have:

[tex]u ^ 2 + 8u + 11 = 0[/tex]

By definition, given an equation of the form [tex]ax ^ 2 + bx + c = 0[/tex]

The quadratic formula, to find the solution can be written as:

[tex]x = \frac{-b+/-\sqrt{b ^ 2-4 (a) (c)} }{2(a)}[/tex]

In this case we have:

[tex]a = 1\\b = 8\\c = 11[/tex]

Substituting in the quadratic formula we have:

Answer:

Option B

x = (- 7 ± √5) / 2

use the substitution u = 2x + 3

equation can now be written as

u² + 8u + 11 = 0

solve for u using the quadratic formula with a = 1, b = 8 and c = 11

u = ( - 8 ± √( 64 - 44 ) )/2

  = ( - 8 ± √20 )/2 = ( - 8 ± 2√5 ) / 2 = - 4 ± √5

change the variable back into terms of  x

2x + 3 = - 4 ± √5 ( subtract 3 from both sides )

2x = - 7 ± √5 ( divide both sides by 2 )

x = ( - 7 ± √5 ) / 2
