Answer:

make a proportion:

                        90% - 76.50$

original price is 100% - x$

x=76.50$*100%/90%=85$

Answer: original price is 85$

Step-by-step explanation:

Answer:

Step-by-step explanation:

If it goes 220 meters and has made 100 revolutions that means that each revolution is 220 meters / 100 = 2.2 meters.

That's the same thing as saying that the wheel has a circumference of 2.2 meters.

Circumference = 2*pi * r = pi * d

2 = pi * d

2 = 3.14 * d

2/3.14 = d

d = 0.6369 meters

z(max) =  256000  Php

x₁ = 10

x₂ = 110

Step-by-step explanation:

Jogging pants design                Selling Price       Cost    

weekly production

 Design A    x₁                                     2500            1750

  Design B    x₂                                    2100            1200      

1. z ( function is : )

z = 2500*x₁  +  2100*x₂       to maximize

First constraint weekly production

 x₁    +   x₂    ≤  120

Second constraint Budget

1750*x₁  +  1200*x₂   ≤   150000      

Then the model is

z = 2500*x₁  +  2100*x₂       to maximize

Subject to

 x₁    +   x₂    ≤  120

1750*x₁  +  1200*x₂   ≤   150000  

General constraints   x₁  ≥  0           x₂   ≥ 0            both integers

First table

z           x₁           x₂        s₁       s₂      cte

1       -2500      -2100    0       0         0

0          1              1          1        0  = 120

0      1750         1200     0       1   = 150000

Using AtoZmath online solver and after 6 iterations the solution is:

z(max) =  256000  Php

x₁ = 10

x₂ = 110

Answer:

The present age of the artifact is 1,600 years

Step-by-step explanation:

let the present age of the artifact = x

let the present age of the book, = y

x = 4y ---- equation (1)

x + 200 = 3(y + 200) ------equation (2)

x + 200 = 3y + 600

substitute in the value of x into the equation;

4y + 200 = 3y + 600

4y - 3y = 600 - 200

y = 400

Then, x = 4 x 400

x = 1,600 years

Therefore, the present age of the artifact is 1,600 years

Answer:

The present age of the artifact is 1,600 years  

Step-by-step explanation:  

let the present age of the artifact = x  

let the present age of the book, = y  

x = 4y ---- equation (1)  

x + 200 = 3(y + 200) ------equation (2)  

x + 200 = 3y + 600  

substitute in the value of x into the equation;  

4y + 200 = 3y + 600  

4y - 3y = 600 - 200  

y = 400  

Then, x = 4 x 400

x = 1,600 years

Answer:

2x+y-2=0

Step-by-step explanation:

Solution

Here,

Passing point P(x,y)= (3,-4)

Slope(m)= -2

Now Equation of the line

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

y+4 = -2x+6

2x +y -2 =0 which is the required equation of the line

Answer: 24 schedules.

Step-by-step explanation:

Given data:

Courses planning to take = 4

Computer courses = 2

Courses from other areas = 2

Solution:

This problem can be solved using permutation.

For Computer science courses.

npr = n! / ( n - r )!

Where n = 4

r = 2

4p2 = 4!/( 4-2)!

= 4!/2!

= 12

For other courses.

Where n = 4

r = 2

4p2 = 4!/( 4-2)!

= 4!/2!

= 12

Jane can have a total of 24 different schedules.

Answer:

[tex]x = 52[/tex]

Step-by-step explanation:

We have the following equation:

[tex]3x -17=2x+35[/tex]

First we simplify the numbers.

[tex]3x -17+17=2x+35+17[/tex]

[tex]3x=2x+52[/tex]

[tex]3x-2x=2x-2x+52[/tex]

[tex]x=52[/tex]

Answer:

x = 52

Answer:

1681

Step-by-step explanation:

In a four digit perfect square, the first two digits and last two digits taken seperately are also perfect squares.

Therefore, the answer is 1681 because 1681=41*41 and

16=4*4 and 81=9*9

Answer:

16.86 ft/s

Step-by-step explanation:

Given that,

Angular speed of a carousel, [tex]\omega=14\ rev/min[/tex]

The diameter of the carousel, d = 23 feet

We need to find the speed of the carousel and jump on.

[tex]\omega=14\ rev/min=1.46\ rad/s[/tex]

Radius, r = 11.5 feet

Let v is the velocity. So,

[tex]v=r\omega\\\\=11.5\times 1.46\\\\=16.79\ ft/s[/tex]

Hernce, the correct option is (d) "16.86 ft/s"

Answer:

The 95% confidence interval for the true population proportion is (0.27, 0.33).

Step-by-step explanation:

The (1 - α)% confidence interval for population proportion of is:

[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

The information given is:

[tex]\hat p=0.30\\n=765\\\text{Confidence level}=95\%[/tex]

The critical value of z for 95% confidence level is, 1.96.

Compute the 95% confidence interval for the true population proportion as follows:

[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

    [tex]=0.30\pm 1.96\times\sqrt{\frac{0.30(1-0.30)}{765}}\\\\=0.30\pm 0.0325\\\\=(0.2675, 0.3325)\\\\\approx (0.27, 0.33)[/tex]

Thus, the 95% confidence interval for the true population proportion is (0.27, 0.33).

Answer:

domain is x is an element of all real numbers, or {xer}, and the range is {3.5}

Step-by-step explanation:

since x stretches the whole way it is all real numbers, and y only touches one point on the graph so it has to be a single point
