which rate is faster 2 feet per second or 2 seconds per foot, or are both rates the same

Answer:

kiloliters

Step-by-step explanation:

The amount of water a family uses in a year is a large amount of water - more than the amount of water in a pool! This means kiloliters would be the best unit of measurement.

Efx=2300

Answer:

y = 3 cm

Step-by-step explanation:

We'll begin by calculating the value of x. This can be obtained as follow:

2x + 6 = 5x – 9 (opposite side of rectangle are equal)

2x + 6 = 5x – 9

Collect like terms

6 + 9 = 5x – 2x

15 = 3x

Divide both side by 3

x = 15 / 3

x = 5 cm

Next, we shall determine the length of the rectangle. This can be obtained as follow:

L = 2x + 6

x = 5 cm

L = 2(5) + 6

L = 10 + 6

L = 16 cm

Finally, we shall determine the value of y. This can be obtained as follow:

Length (L) = 16 cm

Width (W) = y =?

Area (A) = 48 cm²

A = L × W

48 = 16 × y

Divide both side by 16

y = 48 / 16

y = 3 cm

Hi there!

Let think about this...

-6.3-6.3=h

h+6.3=-6.3

negative plus positive is negative...

h=negative number..

6.3+6.3=12.6 add a negative point=-12.6

Final Result: -12.6

Answer:

c

Step-by-step explanation:

Step-by-step explanation:

It's answer is

y = 4x - 6

if x = - 1 Then

y = 4 * (- 4 ) - 6 = - 10

if x = 0

y = 4 * 0 - 6 = - 6

if x = 1

y = 4 * 1 - 6 = - 2

if x = 2

y = 4 * 2 - 6 = 2

hope it will help :)❤

Answer:

6a and a(2*3) and 2(a+2a)

Step-by-step explanation:

2*3a=6a

Answer:

65

Step-by-step explanation:

Using Pythagorean we can say = 33^2 + 56^2 = hypotenus^2

so 1089 + 3136 = 4225

and 4225 rooted = 65

Answer:

65.

You would have to use the Pythagorean theorem in order to find the Hypotenuse (Side that is missing)

Step-by-step explanation:

The equation is:

C = a^2 + b^2 - square root of the answer.

So it would be set up like this.

56^2 = 3136

33^2 = 1089

1089 + 3136 = 4225.

The square root of 4225 is 65.

Thus, 65 is the answer.

Hope this helps!

Answer:

y = (x+2)²-2

Step-by-step explanation:

Use the vertex form y = a(x-h)²+k. Plug in the vertex for h and k. Solve for a and you will get 1 for that value. You can check your answers by plugging in both of those points to make sure.

Answer:

3--1/-2-4=4/-6=2/-3

y=-2/3x+b

-2*-2/3=4/3

3-4/3=5/3

y=-2/3x+5/3

Step-by-step explanation:

Answer:

[tex]\displaystyle y=-\frac{2}{3}x+\frac{5}{3}[/tex]

Step-by-step explanation:

We want to find the equation of the line that passes through the two points:

(4, -1) and (-2, 3).

First, we will find the slope of the two points. So:

[tex]\displaystyle m=\frac{3-(-1)}{-2-4}=\frac{4}{-6}=-\frac{2}{3}[/tex]

Now, we will use the point-slope form given by:

[tex]y-y_1=m(x-x_1)[/tex]

Use either point. I'm going to use (4, -1). So, substitute:

[tex]\displaystyle y-(-1)=-\frac{2}{3}(x-(4))[/tex]

Simplify and distribute:

[tex]\displaystyle y+1=-\frac{2}{3}x+\frac{8}{3}[/tex]

Subtract 1 from both sides. Therefore:

[tex]\displaystyle y=-\frac{2}{3}x+\frac{5}{3}[/tex]

Answer:

¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?

Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800

Step-by-step explanation:

x : Número de DVD del modelo A

y : Número de DVD del modelo B.

                               MODELO A MODELO B TOTAL

Cantidad de caucho                  1x 1x                 50 kg.

Horas de mano de obra           1x 2x                 80 horas

U : Utilidad mensual.

La función objetivo, que se debe maximizar, es:

U=30   + 40y

x+ y [tex]\leq 50\\[/tex]  

x + 2y [tex]\leq 80[/tex]

x[tex]\geq 0[/tex]

y[tex]\geq 0[/tex]

Las coordenadas de los vértices de la región factibles son:

A (0, 0) B (50, 0) C (20, 30) D(0, 40)

Entonces, se evalúa la función objetivo en cada punto:

U (0, 0) = 30 (0) + 40 (0) = 0

U (50, 0) = 30 (50) + 40(0) = 1500

U (90, 0) = 30 (20) + 40 (30) = 1800

U (0, 40) = 30 (0) + 40 (40) =1600

Por consiguiente U tiene un valor máximo en C , en donde: x =20 ,  y = 30 .

Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800.

Answer:

Step-by-step explanation:

[tex]\cos(30^o)=\dfrac{\sqrt3}2[/tex]

From triangle: [tex]\cos(30^o)=\dfrac x2[/tex]

Therefore:

            [tex]\dfrac x2=\dfrac{\sqrt3}{2}\\\\x=\sqrt3[/tex]

there isn't an answer since all the letters are different and you can't add or subtract or do anything to uncommon values. 3x+x = 4x but u can't do 3x +y because they're not in common

Answer:

Step-by-step explanation:

x=5[tex]\sqrt{2}[/tex] because it is an isosceles right triangle , as we have and angle of 45 and one of 90

y is the hypothenuse of the triangle

y^2=(5[tex]\sqrt{2}[/tex])^2+(5[tex]\sqrt{2}[/tex])^2=50+50=100

y=10

the larger triangle is 30-60-90

side opposite of 90 degrees is 2y

r=20

side opposite of 60 degrees is y[tex]\sqrt{3}[/tex]

z=10[tex]\sqrt{3}[/tex]
