How do you find Equivalent Ratios?

Answers

Answer: Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.

Step-by-step explanation:

Answer:

We add up all elements of ratio then place smaller value and set as a fraction if both fractions are equal from 2 sets of ratios then we have equivalent ratios.

Example set of ratios we see 1:2  and  6:3  is equivalent

as 6:3 could be 6/9 just like 3/9 is and 3/9  is ratio equivalent shown can be shown 3/9 = 1/3

As 1:2 = 1/3 or 2/3 and its 1/3 thats shown in workings.

when i solved i got -17/-1, but my calculator says it's 17! i tried searching and it said to divide the fraction to get 17, but why do i have to divide? can someone please help me, thank u!

Answers

Answer:

17

Step-by-step explanation:

The first thing to do is plug in the numbers for the equation. Starting with:

[-20-(-3)]/(19-20)

When you answer that you simplify the answer to

(-20+3)/(19-20)

You answer what is in the parenthesis first.

(-17)/(-1)

After this step you simplify.

17.

The answer is seventeen because any number over 1 is just the number. For example, 3/1=3. The answer is positive because the negative in the numerator and denominator cancel eachother out. leaving the answer as 17.

The answer would be 17 if I’m correct

write an equation using x and y to represent the hanger.

write an equation using x and y to represent the hanger.

Answers

Answer:

Step-by-step explanation:

Givens

The triangle is x

The square is y

Left side

x + 3y is the weight

Right side

4x + y is the weight.

The weights are equal because the hanger is balanced.

Balance equation

x + 3y = 4x + y                 Subtract x from both sides

x-x + 3y = 4x-x + y           Combine

3y = 3x + y                       Subtract y from both sides

3y - y = 3x + y - y             Combine

2y = 3x

Answer

2y = 3x

Answer:

  x +3y = 4x +y

Step-by-step explanation:

A hanger diagram like this is intended to show you that the total weight on the left side is equal to the total weight on the right side.

__

left side

The left side shows 1 triangle and 3 squares. x and y are defined as the weights of the triangle and square, respectively, so the weight on the left side can be represented as ...

  x + 3y

right side

The four triangles and 1 square on the right can have their total weight represented as ...

  4x +y

balance

The intent of the diagram is to show that the left-side weight is equal to the right-side weight. That equality can be written as ...

  x +3y = 4x +y

_____

Additional comment

This problem is not asking for any sort of "solution" or relationship between x and y. We could find such a relationship by solving the equation for y:

  x +2y = 4x . . . . subtract y from both sides

  2y = 3x . . . . . . . subtract x from both sides

  y = (3/2)x . . . . . divide by the coefficient of y

This tells you that the hanger will only be balanced if the weight of a square is half-again as much as the weight of a triangle.

Answers

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

I believe the answer is D.

y is inversely proportional to d²
When d = 10, y = 4
d is directly proportional to x²
When x = 2, d = 24
Find a formula for y in terms of x.
Give your answer in its simplest form.

Answers

Answer:

y = 100 / (9x⁴)

Step-by-step explanation:

y is inversely proportional to d²

y = k/d²

When d = 10, y = 4:

4 = k/10² k = 400

y is:

y = 400/d²

d is directly proportional to x²

d = mx²

When x = 2, d = 24

24 = m*2²m = 24/4m = 6

d is:

d = 6x²

Find a formula for y in terms of x:

y = 400 / d² = 400 / (6x²)² = 400 / (36x⁴) = 100 / (9x⁴)

What is the probability of rolling a number less than or equal to 5 on a fair number
cube? Justify your answer.

Answers

Answer:

Step-by-step explanation:

The probability of rolling a number less than or equal to 5 on a fair number cube (also known as a fair six-sided die) is 5/6.


Justification: A fair number cube has six sides, numbered 1 through 6. Out of these six numbers, there are five numbers (1, 2, 3, 4, and 5) that are less than or equal to 5. Therefore, the favorable outcomes are 5, and the total possible outcomes are 6. Thus, the probability is 5/6.

The probability is 5/6

Construct a triangle with a 70 degree angle, a 85 degree angle, and a 105 degree angle. Did you construct a triangle, if so what type of trianlge is it?

Answers

Answer:

no triangle

Step-by-step explanation:

The sum of the measures of a triangle is 180°.

70° + 85° + 105° = 260°

Since the sum of the given measures is 260°, no triangle with these angle measures can be constructed since it cannot exist.

No because a triangle is 180. These three numbers equal 260.
