14 is 28% of what number?

Mathematics

8 0

1% of the number would be 14/28 which is 0.5. therefore 100% would be 0.5 x 100 which equals 50.

On a coordinate plane, a line has points (negative 2, negative 4) and (4, 2). Point P is at (0, 4). Which points lie on the line

NikAS [45]

Answer:

the correct options are:

(–1, 3), (–2, 2) and (–5, –1)

Step-by-step explanation:

Given that a line passes through two points

A(-2, -4) and B(4, 2)

Another point P(0, 4)

To find:

Which points lie on the line that passes through P and is parallel to line AB ?

Solution:

First of all, let us the find the equation of the line which is parallel to AB and passes through point P.

Parallel lines have the same slope.

Slope of a line is given as:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{2-(-4)}{4-(-2)} = 1$

Now, using slope intercept form ( $y = mx+c$ ) of a line, we can write the equation of line parallel to AB:

$y =(1)x+c \Rightarrow y = x+c$

Now, putting the point P(0,4) to find c:

$4 = 0 +c \Rightarrow c = 4$

So, the equation is $\bold{y=x+4}$

So, the coordinates given in the options which have value of y coordinate equal to 4 greater than x coordinate will be true.

So, the correct options are:

(–1, 3), (–2, 2) and (–5, –1)

12 is a common denominator of 1/4 and 1/3

viktelen [127]

True... both 3 and 4 are factors of 12 so it can be used as a common denominator.

1/3 × 4/4 = 4/12
1/4 × 3/3 = 3/12

Brooklyn Cabinets is a manufacturer of kitchen cabinets. The two cabinetry styles manufactured by Brooklyn are contemporary and

maria [59]

Answer:

See Step by step explanation

Step-by-step explanation:

Objective Function: z

x = number of contemporary style

y = number of farmhouse style

Costs

Carpentry costs:

15*2*x + 15*2,5*y = 30*x + 37,5*y

Painting costs

12*1,5*x + 12*1*y = 18*x + 12*y

Finishing costs

18*1,3*x + 18*1,2*y = 23,4*x + 21,6*y

Total costs:

30*x + 37,5*y + 18*x + 12*y + 23,4*x + 21,6*y

71,4*x + 71,1*y

z = 90*x + 85*y - ( 71,4*x + 71,1*y ) to maximize

z = 18,6*x + 13,9*y to maximize

Subject to:

First constraint:

Hours available in carpentry 3000

2*x + 2,5*y ≤ 3000

Second constraint

Hours available in painting 1500

1,5*x + 1*y ≤ 1500

Third constraint

Hours available in finishing 1500

1,3*x + 1,2*y ≤ 1500

Fourth constraint

Minimum quantity of contemporary style 500

x ≥ 500

Fifth constraint

Minimum quantity of farmhouse style 650

y ≥ 650

General constraints:

x ≥ 0 y ≥ 0 x , y integers

Model:

z = 90*x + 85*y - ( 71,4*x + 71,1*y ) to maximize

Subject to:

2*x + 2,5*y ≤ 3000

1,5*x + 1*y ≤ 1500

1,3*x + 1,2*y ≤ 1500

x ≥ 500

y ≥ 650

x ≥ 0 y ≥ 0 x , y integers
