?/1 A box contains 5 red marbles and 7 green marbles. Find the probability of drawing a green marble and not returning it to the box and then drawing a red marble?

Answer:

y = 2x+1

Step-by-step explanation:

From the question,

Using the equation of a straight line

y = mx+c................. Equation 1

Where m = slope of the line, c = intercept on the y axis.

From the graph, The two point co-ordinate shown os

Point 1 = (-2,0)

Point 2 =(6,4)

s = (y₂-y₁)/(x₂-x₁).............. Equation 2

Where y₂ = 6, y₁ = -2, x₂ = 4, x₁ = 0

Substitute into equation 2

s = (6-(-2))/(4-0)

s = (6+2)/4

s = 8/4

s = 2.

Also from the graph,

c = 1

Substitute these values into equation 1

y = 2x+1

Hence the equation of the line is y = 2x+1

Answer:

450 feet

Step-by-step explanation:

60ft = 4 seconds

x ft = 30 seconds

(cross multiply)

60 * 30 = 4x

1800= 4x

(divide both sides by 4)

x= 1800/4= 450

Answer:

ur answer would be 450 feet

39in³ is a required volume.

Solution given:

for upper one

length[l]=8in

breadth[b] =3in

height[h]=1in

now

volume [V1]=l×b×h=8×3×1=24in³

again for lower one:

length[l]=6-1=5in

breadth[b] =3in

height[h]=1in

volume [V2]=l×b×h=5×3×1=15in³

Again

total volume =V1+V2=24in³+15in³=39in³

Answer:

Caja de plaquetas = x = 30 €

Caja de azulejos = y = 35 €

Step-by-step explanation:

Deje que el costo de

Caja de plaquetas = x

Cuadro de mosaico = y

Por Berta

Para reformar su cocina, Berta compró la semana pasada 2 cajas de baldosas de plaquetas para el suelo y 4 cajas de baldosas para la pared por 200 €.

2x + 4y = 200 ...... Ecuación 1

Hoy

Hoy compré 2 cajas más de plaquetas y otras 2 de tejas por 130 €.

2x + 2y = 130 ..... Ecuación 2

Resolvemos usando el método de Eliminación

2x + 4y = 200 ...... Ecuación 1

2x + 2y = 130 ..... Ecuación 2

Restar la ecuación 2 de 1

2 años = 70

y = 70/2

y = 35 €

Resolviendo para x

2x + 4y = 200 ...... Ecuación 1.

2x + 4 × 35 = 200

2x + 140 = 200

2x = 200 - 140

2x = 60

x = 60/2

x = 30 €

el costo de

Caja de plaquetas = x = 30 €

Caja de azulejos = y = 35 €

Answer:

210 m

Step-by-step explanation:

Perimeter is the distance around the outside of a two-dimensional shape.

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.

Christen ran around the soccer field, so she ran around the perimeter.

We can find the perimeter by adding all of the side lengths.

Perimeter=60 m+45 m+60 m+45 m

Christen ran 210m.

Answer:

29

Step-by-step explanation:

In a triangle, a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

Given this formula, we knoe c^2 is the product of 21^2 + 20^2.

This gives you 841. Now you just find the square root of 841 which is 29.

Hope this helps :)

BDC=95

Answer:

[tex] m\angle BDC = 95\degree [/tex]

Step-by-step explanation:

[tex] In\: \triangle ACD\: \&\:\triangle BDC[/tex]

[tex] m\angle A = m\angle B[/tex] (given)

[tex]\because m\angle A = 50\degree [/tex]

[tex]\therefore m\angle B = 50\degree [/tex]

[tex] m\angle ADC = m\angle BCD[/tex] (given)

[tex]\because m\angle ADC = 35\degree [/tex]

[tex]\therefore m\angle BCD= 35\degree [/tex]

[tex] In\: \triangle BDC[/tex]

[tex] m\angle BDC = 180\degree - (m\angle B+m\angle BCD) [/tex]

(By angle sum postulate of a triangle)

[tex] m\angle BDC = 180\degree - (50\degree +35\degree ) [/tex]

[tex] m\angle BDC = 180\degree - (50\degree +35\degree ) [/tex]

[tex] m\angle BDC = 180\degree - 85\degree [/tex]

[tex] m\angle BDC = 95\degree [/tex]

Answer:

they want u to replace the letters with the numbers and then solve the equation. so instead of having c/a+2b they want you to write 6/3+2(-4)

then they want u to solve it. 6/3=2 and 2(-4)=-8 finally add 2 and -8 to get the answer -6. (you probably need to write it step by step not just say what the answer is)

Answer:

y = 4x + 1

Step-by-step explanation:

Given the equation y = 4x - 2, we need to find the equation parallel to this line. Note that for two equations to be parallel to each other, the must have the same slope

Standard form of an equation is y = mx + b

Compare;

mx = 4x

m = 4

Since the slope of the given equation is 4, the required equation must also have a slope of 4

Since we are not given an option, we can assume any equation with a slope of 4

y = 4x + 1 will be parallel to the given equation since they both have the same slope

Note that the equation can be different so far they have the slope of 4
