Step-by-step explanation:

Answer:

15x + 25y ≥ 400

x + 2y ≤ 20

x ≥ 0, y ≥ 0

Step-by-step explanation:

Here, we are modelling the total number of hours she can use in making images in a week and the total amount that can be earned in a week, considering the given constraints.

Number of small images in a week = x

Number of hrs in making images if it takes 1 hr to make 1 = 1*x = x

Number of large images in a week = y

Number of hrs in making large images if it takes 2 hrs to make 1 = 2*y = 2y

Given that she has up to 20 hrs to make the images, therefore, the inequality that models this situation would be:

x + 2y ≤ 20

This implies that, the hours spent altogether can be less than or equal to 20hrs

Amount for small images = $15

Amount in total for all images made in a week = $15*x = 15x

Amount for large images = $25

Amount in total for all images made in a week = $25*y = 25y

Given that she can earn AT LEAST $400 in a week, therefore, the inequality that models this situation would be:

15x + 25y ≥ 400

This implies that, the amount she wants to make in a week would be $400 or more.

The system of inequalities would be:

x + 2y ≤ 20

15x + 25y ≥ 400

x ≥ 0, y ≥ 0

Answer:

500 = 100%

20% = 60

Step-by-step explanation:

300 = 60%

50 = 10%

500 = 100%

100% = 300

10% = 30

20% = 60

Answer:

60% of 750 = 300

60 out of 300 = 20%

Answer:

$31.80

Step-by-step explanation:

first convert 6% into a decimal which is 0.06. then multiply 30 by 0.06 to get 6% of 30 which is 1.80. then add 1.80 to 30 to get your final cost of 31.80

[tex]30*0.06=1.80[/tex]

[tex]30+1.80=31.80[/tex]

final cost: $31.80

Given parameters:

Number of pencils = [tex]4\frac{1}{2}[/tex] pencils

Time taken = [tex]3\frac{1}{3}[/tex] minutes

Unknown:

Number of pencils produced in 1 minute;

Solution:

To solve this problem, let us first find the rate of the machine;

       Rate of machine = [tex]\frac{number of pencils }{time taken}[/tex]

       Rate of machine = [tex]\frac{\frac{9}{2} }{\frac{10}{3} }[/tex]   = [tex]\frac{9}{2} x \frac{3}{10}[/tex]   = [tex]\frac{27}{20}[/tex] pencils/minute

Now, number of pencils produces in 1 minute;

            Number of pencils  = rate of machine x time taken

             Number of pencils = [tex]\frac{27}{20}[/tex]  pencils/ min x 1 min

             Number of pencils = [tex]\frac{27}{20}[/tex]pencils

The number of pencils produced in 1 minute is [tex]\frac{27}{20}[/tex]

Answer:

x= 85

Step-by-step explanation:

(7x+6)-(5x-4)=180

There is a negative 1 between the two parenthesis

-1(5x-4)

-5x+4

Now plug it back into the equation and take out the parenthesis

7x+6-5x+4= 180

2x+10=180    Now we can solve

    -10  -10

2x= 170

2x/2 = 170/2

x= 85

Answer:

$23.75

Step-by-step explanation:

As 20% equals to [tex]\frac{20}{100}[/tex], which is the same as 0.20, then all you have to do to get to the answer is to calculate:

0.2 * 118.75 = $23.75

The variable that was defined and the corresponding inequality to depict the constraints is; r < 140 beats per minute.

We are to define a variable and write an inequality for the given question.

Now, since the variable here is the heart rate, then let us define the varibale with the term r.

Thus, the inequality that represens the given question is written as;

r < 140 beats per minute.

The algebraic expression for the nth term in this pattern is n^2 + 3n

Step-by-step explanation:

We want an algebraic expression for the nth term in this pattern.

Like we are told, there must be an expression that includes the term n^2

So therefore;

We need to express each of the terms to include the n^2 term

Kindly note that the n notation will represent the term number of the value we are considering. Let’s take it one after the other.

for 4; 1^2 + 3(1)

For 10; 2^2 + 3(2)

For 18; 3^3 + 3(3)

For 28; 4^2 + 3(4)

For 50; 5^2 + 3(5)

So the nth term will be;

n^2 + 3n

Answer:

The value is  [tex]    e  =  1.92 [/tex]

Step-by-step explanation:

From the question we are told that

   The formula for radius of curvature is [tex]R = \frac{1600}{15} +127e[/tex]

   The design speed of the roadway is  [tex]v =  40 \ km/hr[/tex]

    The value of radius of curvature considered R =  350 m

From the equation given e is the superelevation rate

Now making the subject of the formula

        [tex]    e  =  \frac{R}{127}  - \frac{1600}{1905} [/tex]

At R= 350

         [tex]    e  =  \frac{350 }{127}  - \frac{1600}{1905} [/tex]

          [tex]    e  =  1.92 [/tex]

Here, we are required to determine the maximum superelevation rate, e (rounded to 2 decimal places) recommended if the radius of curvature, R is 350 meters.

The answer is e = 1.92 (rounded to 2 decimal places).

First, from the information given, the minimum radius of curvature, R is related to the maximum superelevation rate, e by the formular;

R = (1600/15) + (127e)

Therefore, to evaluate the value of e for R = 350, we have;

350 - (1600/15) = 127e.

350 - (1600/15) = 127e.350 - 106.667 = 127e

Therefore, 243.333 = 127e.

Therefore, e = 1.9160meters

As a result, The maximum superelevation rate, e recommended if the radius of curvature, R is 350 meters is:
