To find the ratio decimal form, write each ratio as it's corresponding fraction, then divide. Simplify fractions, if possible.

2:3= 2/3= 0.6666666= 0.67 rounded

3:7= 3/7= 0.42857= 0.43 rounded

3:6= 3/6= 1/2= 0.5

3:8= 3/8= 0.375

2:5= 2/5= 0.4

3:7= 3/7= 0.42857= 0.43 rounded

2:4= 2/4= 1/2= 0.5

Hope this helps! :)

Question

the greatest common factor gcf of 2 monomiald is 3x^2y. One of the monomials is 3x^4y . Which couod be the other monomial.

Solution 1

While I cannot see your answer choices, the correct answer would be one that has a coefficient that is a multiple of 3 and has an x raised to an exponent of no more than 2. It could have any other variables in it.

The reason this has to be is because of the GCF. Since 3 is part of the GCF, and the other monomial has a coefficient of 3, this means the missing monomial must be divisible by 3 as well.

Since x² is part of the GCF, the missing monomial must contain x². However, if it were to contain x³ or anything larger, the GCF would have x with a higher exponent.

Question

how do I solve a problem in which radicals with unlike terms are added? E.g. (Square root of 3) + (two times the square root of 108) + (four times the square root of 75)

Solution 1

By making all three roots to be square roots of 3. And then add them.

Question

Which graph is the solution to the system y > 2x – 3 and y < 2x + 4?

Solution 1

The solution **region **of the inequalities y > 2x - 3 and y < 2x + 4 would be the region between the parallel lines y = 2x - 3 and y = 2x + 4.

Linear Inequalities are the statements in mathematics where the left and right hand side are separated using inequality **symbols **like <, >, ≤ and ≥.

We have the **system **of inequalities given here:

y > 2x - 3 and

y < 2x + 4

To solve this first take the inequalities as **equations **y = 2x - 3 and y = 2x + 4.

Take y = 2x - 3

When x = 0, then y = -3

When x = 1, then y = -1

When y = 0, then x = 1.5

We get three **points **here (0, -3), (1, -1) and (1.5, 0).

Draw a line passing through these points.

**Substitute **(x, y) as (0, 0), then the inequality y > 2x - 3 become 0 > -3, which is true. Therefore solution region is the region containing the origin.

Similarly, take y = 2x + 4.

When x = 0, then y = 4

When x = 1, then y = 6

When y = 0, then x = -2

We get three points here, (0, 4), (1, 6) and (-2, 0).

Substitute (x, y) as (0, 0), then the inequality y < 2x + 4 become 0 < 4, which is true. Therefore solution region is the region containing the **origin**.

Hence the **solution **region of these inequalities would be the region lower to the line y = 2x + 4 and the region upper to the line y = 2x - 3.

Question

What is a 4:1 ratio? Is it equivalent to 75% to 25%?

Solution 1

Ratios are basically:

for this much of this:theres this much of that

lets say you have 4:1 in spoons and forks.

for every 4 spoons, there is 1 fork. if there is 8 spoons there are 2 forks and so on.

The percent is 400%

if you meant 1:4 the percent would be 25%. all other rules apply.

for every 1 spoon you have 4 forks.

Question

99 Points Need Help! How to reflect over y= -x+6

Solution 1

To reflect in the line y = -x + 6, we translate everything down 6 first. This will make it seem like we are reflecting in the line y = -x

(x,y) → (x, y-6)

Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative

(x,y) → (-(y-6), -x)

Then we move everything back up again

(x,y) → (-(y-6), -x + 6)

I will present to you an example. Reflect the point (-4, 8) in the line y = -x + 6.

(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)

You should graph this out to confirm with the reflection line.

(x,y) → (x, y-6)

Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative

(x,y) → (-(y-6), -x)

Then we move everything back up again

(x,y) → (-(y-6), -x + 6)

I will present to you an example. Reflect the point (-4, 8) in the line y = -x + 6.

(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)

You should graph this out to confirm with the reflection line.

Solution 2

** (x,y) → (-(y-6), -x + 6) **

Question

Please Help!!!!!! So i know how to reflect over line y=-x but how would i do it over line y=-x+6. An example would be helpful and a rule for more problems of this kind.

Solution 1

(x,y) → (x, y-6)

Then, to reflect in the line y = -x, we switch the x- and y-coordinates and then make them negative

(x,y) → (-(y-6), -x)

(-4,8) → (-(8-6), -(-4) + 6) → (-2, 10)

Question

PLEASE!!! I NEED THIS ANSWER DESPERATELY Data is collected for the average april temperature and degree of latitude The line of best bit for the data is found where L is the degree of latitude and T is the temperature in degrees Fahrenheit
T = -7/6I + 84
Predict the temperature at a latitude of 60

Solution 1

The answer to this question is 14 degrees Fahrenheit.

T(60) = (-7/6)(60) + 84 = 14

T(60) = (-7/6)(60) + 84 = 14

Solution 2

The answe is 14 I hope I helped

Question

(3n-1)(3n+2)
...anyone know this?...

Solution 1

The answer to this question is 9n^2+3n-2. We expand this polynomial factored with the distributive property

(3n-1)(3n+2) = 3n(3n-1)+2(3n-1) = 9n^2 - 3n + 6n - 2 = 9n^2 + 3n - 2

(3n-1)(3n+2) = 3n(3n-1)+2(3n-1) = 9n^2 - 3n + 6n - 2 = 9n^2 + 3n - 2

Solution 2

The first step for solving this expression is to multiply each term in the first parenthesis by each term in the second parenthesis (FOIL method)

3n × 3n + 3n × 2 - 3n - 2

Calculate the product of the first two numbers.

9n² + 3n × 2 - 3n - 2

Calculate the product of the next set of multiplication.

9n² + 6n - 3n - 2

Collect the like terms that have a variable of n to get your final answer.

9n² + 3n - 2

This means that the correct answer to your question is going to be 9n² + 3n - 2.

Question

A video game was $38. This weekend the game will be marked 13 percent off. How much is the game this weekend?

Solution 1

Discount = 13% x $38 = 0.13 x 38 = $4.94

Cost of the game after discount = $38 - $4.94 = $33.06

**Answer: $33.06**

Cost of the game after discount = $38 - $4.94 = $33.06
