triangles ABC and DEF are similar. what is the length of side EF

Answers

the anwser is either 2.88 or 3, But others are saying it is 3.

Answer:

The length of the side EF is 3cm.

Step-by-step explanation:

As both triangles are similar, their corresponding sides are in proportion.

This means that:

[tex]\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}[/tex]

[tex]\frac{3}{4.5}=\frac{2}{x}=\frac{5}{7.5}[/tex]

This proportion is called the scale factor.

Knowing this, we can find the value of x

[tex]\frac{3}{4.5}=\frac{2}{x}[/tex]

[tex]x=2 *(\frac{4.5}{3})=\frac{9}{3}=3cm[/tex]

So, the lenght of side EF is 3cm.

Which statements about opposites are true?

Select each correct answer.

The opposite of a number is always a negative number.

The opposite of the opposite of a number is the number itself.

A non-zero number and its opposite are located on opposite sides of zero on a number line.

The opposite of a number is 1 divided by that number.

Answers

The opposite of the opposite of a number is the number itself.
Final answer:

The opposite of a number is the same distance from zero on the number line but on the other side. Therefore, the opposite of a number is not always negative, the opposite of the opposite of a number is the number itself, and non-zero numbers and their opposites are on opposite sides of zero. The reciprocal of a number (1 divided by that number) is not its opposite.

Explanation:

In the realm of mathematics, the term 'opposite' refers to the number that is the same distance from 0 on the number line, but on the other side. With this definition, we can state that:

The opposite of a number is not always a negative number. For example, the opposite of -7 is 7, which is positive.The opposite of the opposite of a number is indeed the number itself. For instance, the opposite of -3 is 3, and the opposite of 3 is -3.A non-zero number and its opposite are indeed located on opposite sides of zero on a number line.The opposite of a number is not 1 divided by that number - this is actually the reciprocal of a number, not its opposite.

The balance in two separate bank accounts grows each month at different rates. The growth rates for both accounts are represented by the functions f(x) = 2x and g(x) = 4x + 12. In what month is the f(x) balance greater than the g(x) balance?

Month 6
Month 5
Month 4
Month 3

Answers

From the balance and the growth you are talking to me, we can say that it would be an inequality of 2x > 4x +12 so in that case it would be in the month number 6 where you would find a greater balance.

Between which two whole numbers is the square root of 18?

Answers

4 and 5. The square root of 16 is 4 , the square root of 25 is 5. Those two numbers are the closest to 18.
It is between 4 and 5 because when you set up the question, you put 18 in a square root sign and solve. As In:
                                                     16*Squared  = 4
                                                     18*Squared = It's between 4 and 5

can every odd whole number be written as the difference of two squares

Answers

No. Not every odd number can be written as the dif of 2 squares

Every odd whole number can indeed be written as the difference of two squares, leveraging the fact that the difference between the squares of consecutive integers is an odd number.

The question whether every odd whole number can be written as the difference of two squares is of arithmetical and algebraic interest. The answer is yes, every odd whole number can be expressed as such. For example, consider the odd whole number 7. This number can be expressed as 4^2 - 3^2, which simplifies to 16 - 9, giving us 7. Generally, for any odd whole number n, we can find whole numbers x and y such that n = x^2 - y^2. This is because we can write n = (m+1)^2 - m^2, where m is an integer. Essentially, m can be taken as (n-1)/2 which ensures that m and m+1 are consecutive integers, hence their squares differ by an odd number, which is n.

In a taste test people were asked which of 4 soft drinks they liked best. of those surveyed 1/3 chose orange crush 2/5 chose killa kola and 1/6 chose lime sublime. what fraction chose the fourth drink pls show all work and answer

Answers

Final answer:

To find the fraction of people who chose the fourth drink, we subtract the fractions of people who chose the other three drinks from 1. The fraction is 3/30.

Explanation:

To determine the fraction of people who chose the fourth drink, we need to subtract the fractions of people who chose the other three drinks from 1.

The fraction of people who chose Orange Crush is 1/3, the fraction of people who chose Killa Kola is 2/5, and the fraction of people who chose Lime Sublime is 1/6.

To find the fraction of people who chose the fourth drink, we subtract the sum of these three fractions from 1: 1 - 1/3 - 2/5 - 1/6.

To simplify this calculation, we can find a common denominator for the fractions. The least common multiple of 3, 5, and 6 is 30.

Converting the fractions to have a denominator of 30, we get: 30/30 - 10/30 - 12/30 - 5/30 = 3/30.

Therefore, the fraction of people who chose the fourth drink is 3/30.

Answers

In terms of notation "sqrt(-48)" means " square root of -48 "

We'll factor and use the rule sqrt(x*y) = sqrt(x)*sqrt(y) to simplify this expression

sqrt(-48) = sqrt(-1*48)
sqrt(-48) = sqrt(-1)*sqrt(48) ... using rule mentioned above
sqrt(-48) = i*sqrt(48) ... use i = sqrt(-1)
sqrt(-48) = i*sqrt(16*3) ... factor
sqrt(-48) = i*sqrt(16)*sqrt(3) ... using rule mentioned above
sqrt(-48) = i*4*sqrt(3) ... Simplify
sqrt(-48) = 4i*sqrt(3) ... Rearrange terms

The final answer is 4i*sqrt(3), which is choice C

we pick two points from the graph

Lets pick (-2,1)  and (0,-2)

We find the slope using two given points

[tex]slope = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

(-2,1) is (x1,y1)  and (0,-2) is (x2,y2)

Plug in the values in the slope formula

[tex]slope = \frac{-2 - 1}{0 - (-2)}[/tex]

[tex]slope = \frac{-3}{2}[/tex]

To frame equation we use equation y = mx + b

Here y intercept is -2 that is our b

So equation becomes [tex]y=\frac{-3}{2} x -2[/tex]

Answer:

The answer is f(x) = -3/2x - 2

Assuming 5/2y is the fraction,

Okay so first off I do not know if any of these are completely correct, as well as I totally forgot how to solve the last two. Either way, this is what I got for them. 
The first is true
The second would be true although -88 squared is 7744 and the equation equals -7744 which can not be obtained by a square number of negative times a negative is a positive number. The third is not true for you do have -a^2 and -b^2 but you also end up with aB as well as -bA. The fourth in decimal form would be.167 The fifth again in decimal form would be 1.732 Then the next would be 0. Finally, the next one would be .090 Again, I do not know how to solve the last two and I honestly do not know if anyone of these is correct.

A cube has edge length 5in use a exponent to express volume

Answers

5 cubed ( or an exponent of three )
What exponents do you know that share names with different kinds of shapes? It may surprise you (or not) to discover that taking the square of a number and taking the cube of a number both derive their names from finding the space inside a square and a cube respectively. For squaring (as in x²) this corresponds to calculating the area of a square with side lengths x. For cubing (as in x³), it corresponds to calculating the volume of a cube with edge lengths x.

So, if we want to find the volume of a cube with edge length 5 in, we just need to find the value of 5³. (Keep in mind that our final units will be in in³)

A. 2 1/2

B. 3

C. 3 1/2

Answers

Answer:

At the end of the 5 days week, the number cups of oatmeal left are 59/18.

Step-by-step explanation:

Given that the container has 5 and half or 11/2 cup of oatmeal. Every morning Liam at 4/9 cups of oatmeal and this took place for 5 days. So, multiply it with 5. The total cups of oatmeal for 5 days will be 20/9.

The cups of oatmeal left after 5 days are

(11 / 2) - (20 / 9)

(99 - 40) / 18

59 / 18

So, 59/18 number of cups of oatmeal are left at the end of 5 days.
