There are only green yellow blue cubes in a bag
Answer:
1 ÷ 11
Step-by-step explanation:
The computation is shown below:
let us assume the yellow cubes be x
So, blue cubes be 2x
And, green cubes be 2x (4) 8x
Now the ratio is
Yellow: Blue: green
x:2x:8x
1:2:8
Now the probability of yellow cubes is
= 1 ÷ (1 + 2 + 8)
= 1 ÷ 11

What would be the solution to the system of equations: y= -x + 4 y= 3x
Answer:
Step-by-step explanation:
The value of y is given in equation 2
Putting value of y = 3x in equation 1
Y = - x + 4
3x = - x + 4
Bringing like terms on one side
3x + x = 4
4x = 4
x = 4/4 = 1
Now putting value of x = 1 in equation 2
Y = 3x
Y = 3(1) = 3

-4(y-2)=12
what is y
Answer:
y= -1
Step-by-step explanation:
Answer:
The answer would be y= -1
Step-by-step explanation:
When we have a number outside the parenthesis we do the rainbow method where we multiply the number on the outside of the parenthesis to the numbers inside the parenthesis so
-4*y= -4y and -4*-2=8
-4y+8=12
-4y=4
y=-1

Parallelogram A B C D is shown. The length of A B is (9 x minus 14) inches and the length of D C is (3 x + 4) inches. In parallelogram ABCD, what is DC? 3 in. 9 in. 13 in. 19 in.
Given:
In a parallelogram ABCD, AB=(9x-14) inches and DC=(3x+4) inches.
To find:
The measure of DC.
Solution:
We know that opposite sides of a parallelogram are equal.
In the parallelogram ABCD, AB and DC are opposite sides. So,
[tex]AB=DC[/tex]
[tex]9x-14=3x+4[/tex]
[tex]9x-3x=14+4[/tex]
[tex]6x=18[/tex]
Divide both sides by 6.
[tex]x=\dfrac{18}{6}[/tex]
[tex]x=3[/tex]
Now,
[tex]DC=3x+4[/tex] inches
[tex]DC=3(3)+4[/tex] inches
[tex]DC=9+4[/tex] inches
[tex]DC=13[/tex] inches
The measure of DC is 13 in.
Therefore, the correct option is C.
Answer:
13in

Write the equation for the line whose slope is -1/4 and goes through the point (-2,6)
Answer:
[tex]y = -\frac{1}{4} + \frac{11}{2}[/tex]
Step-by-step explanation:
use y = mx + b where:
y = y-coordinate = 6
m = slope = -1/4
x = x-coordinate = -2
b = y-intercept = what we're solving for to complete the equation
plug the values into the equation
[tex]6 = -\frac{1}{4}(-2) + b[/tex] multiply [tex]-\frac{1}{4}[/tex] and 2
[tex]6 = \frac{1}{2} + b[/tex] subtract [tex]\frac{1}{2}[/tex] from both sides
[tex]b = \frac{11}{2}[/tex]
now we plug m and b into the equation and leave x and y as variables to get the final equation:
[tex]y = -\frac{1}{4} + \frac{11}{2}[/tex]
Find the y-intercept:
1/3x + y = 6

the length and breadth of a rectangular plot is in the ratio of 4:3. if the perimeter is 140m, find the length and breadth of a rectangle
Answer:
l = 40 m and b = 30 m
Step-by-step explanation:
Let the length and breadth of a rectangle be 4x and 3x.
We know that,
The perimeter of a rectangle is given by :
P = 2(l+b)
140 = 2(4x+3x)
70 = 7x
x = 10
Length, l = 4x = 4(10) = 40 m
Breadth, b = 3x= 3(10) = 30 m
So, the length and breadth of a rectangle are 40 m and 30 m respectively.

Answer: 7ft
Step-by-step explanation:
The shape is a trapezium
Area of Trapezium= (1/2)(a+b)(h)
Area of Trapezium= 40sqft
a= x
b= 9ft
h= 5ft
40= (1/2)(x+9)(5)
40= (5(x+9)/2)
Cross multiply
80= 5(x+9)
80= 5x + 45
5x= 80-45
5x= 35
Divide both sides by 5
x= 7

CAN I GET SOME HELP PLEASE?
Answer:
m = 8
n = 9
Step-by-step explanation:
Remark
By similar triangles
(m - 4) /8 = 8 / 2m Cross multiply
2m(m - 4) = 64 Expand the left
2m^2 - 8m = 64 Divide through by 2
m^2 - 4m = 32 Subtract 32 from both sides.
m^2 - 4m - 32 = 0 Factor
(m - 8)(m + 4) = 0
m + 4 has no meaning in geometry. - numbers cannot be distances.
m - 8 = 0
m = 8
===================
By the same kind of similar triangles used in problem A we get
7 / x = x / 9
x^2 = 63
Just leave this as it is. We'll solve this by the Pythagorean Theorem.
x^2 + 9^2 = (n + 3)^2
63 + 81 = (n + 3)^2
144 = (n + 3)^2 Take the square root of both sides
12 = n + 3 Subtract 3 from both sides.
9 = n

a: b = 1:7
a:c= 4:1
How many times bigger is b than c?
Answer:
a / b = 1/7
b = a x 7
a / c = 4 /1
a = c x 4
b = a x 7
= c x 4 x 7
= c x 28
b is 28 times bigger than c
b is 28 times bigger than c. The conclusion is obtained by rearranging the equations.
What exactly are ratio and proportion?A ratio is an ordered pair of integers a and b, expressed as a/b, where b cannot be zero. A proportion is an equation that sets two ratios equal to each other.
The given ratio;
a: b = 1:7
a:c= 4:1
Rearrange the given ratio we obtained;
b = a × 7
a = c × 4
Put the value of a in b get;
b= c × 4 × 7
Hence, b is 28 times bigger than c.

What is the solution set of this inequality? 3|p + 4| + 5 < 8 (–5, –3) (–3, 0) (0, –5) (3, 5)
Given:
The inequality is
[tex]3|p+4|+5<8[/tex]
To find:
The solution set for the given inequality.
Solution:
We have,
[tex]3|p+4|+5<8[/tex]
[tex]3|p+4|<8-5[/tex]
[tex]3|p+4|<3[/tex]
Divide both sides by 3.
[tex]|p+4|<1[/tex]
It can be written as
[tex]-1<p+4<1[/tex]
Subtracting 4 from each side, we get
