Find the value of x that makes m congruent to n​

Step-by-step explanation:

Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX

"K" is the constant of proportionality and must be determined from the initial information.

If Y = 2/3 when X=1/12means 2/3=1/12

K = 2/3÷1/12 = 8

Now that we know the value of K, we can use it to calculate the value of Y when X=1/2

Y = (8)(1/2) = 8/2=4

Y=4

Answer:

x/x+3

Step-by-step explanation:

first off, we start by factorizing.

we start with the numerator  taking x out making it x (x-3) / x^2 - 9

then we factorize the denominator a bit more...making it x (x-3) /  (x-3) (x+3)

as you can tell there is a (x-3) on both sides. so we can cross them out.

x/x+3 is left. try it yourself again so you can understand other questions like this! I hope I could help!

The area of figure = 600 cm ²

Step-by-step explanation:

Area of this figure = area of triangle + area of rectangle

Area of triangle = 1/2 × base × height

Area of rectangle = length× breadth

=> (1/2 × 20 × 20 ) + ( 20×20 )

=> 200 + 400

=> 600 cm²

Answer:

P' (- 3, 1 )

Step-by-step explanation:

the translation

(x, y ) → (x - 6, y + 5 )

means subtract 6 from the x- coordinate and add 5 to the y- coordinate, so

P (3, - 4 ) → P' (3 - 6, - 4 + 5 ) → P' (- 3, 1 )

Answer:

P(vanilla cupcake)= 1/2

Step-by-step explanation:

Knowing that:

3 vanilla cupcakes

3 other cupcakes

Total = 6

To Find:

What is the experimental probability that the next cupcake sold will be a vanilla cupcake?

Write your answer as a fraction or whole number.

P(vanilla cupcake)=

Solve:

Experimental probability is expressed as:

(Favorable outcomes) / (Total outcomes)

The favorable outcome in this situation is vanilla cupcakes. There were 3 vanilla cupcake sold, so this is the numerator of our fraction.

To find the total outcomes we add 3 + 3, which equals 6. This will be the denominator of our fraction.

The fraction used to express experimental probability will be: 3/6

We can further simplify this to 1/2.

Thus:

P(vanilla cupcake)= 1/2 or 3/6

Answer:

4/41

Step-by-step explanation:

Given that C varies directly as N, the value of Calories C when the number of ounces N is increased to the given value is 684 calories.

Proportional relationships are relationships between two variables where their ratios are equivalent.

Direct variation equation is a linear equation in two variables.

It is expressed as;

a ∝ b then a = kb

Where k is the proportionality constant.

Given the data in the question;

Since Calories C and Number of ounces N varies directly, we find their proportionality constant.

a ∝ b then a = kb

C = kN

380 calories = k × 20 ounces

k = 380 calories / 20 ounces

k = 19 calories/ounces

Now,we find C when N is 36 ounces.

C = kN

C = 19 calories/ounces × 36 ounces

C = 684 calories

Given that C varies directly as N, the value of Calories C when the number of ounces N is increased to the given value is 684 calories.

Answer:

Use simultaneous equation for this problem

y= number of adults

x = number of children

3y + 2x = 160

y + x = 60

then we double the second equation

3y + 2x = 160

2y + 2x = 120

we cancel x by elimination

3y - 2y = 160 - 120

Triangular prism

Step-by-step explanation:

Got it right on edge 2022 :)

The three-dimensional figure that has exactly three rectangular faces is a rectangular pyramid

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

Let the pyramid be represented as A

Now , A rectangular prism has 6 faces, where each face is a rectangle.

A rectangular pyramid has 5 faces, where 4 faces are triangles and 1 face is a rectangle.

A triangular prism has 5 faces, where 2 faces are triangles and 3 faces are rectangles.

A triangular pyramid has 4 faces, where 3 faces are triangles and 1 face is a rectangle.
