Which ratios are equivalent to 8 : 12? Select all that apply. A 4 : 6 B 12 : 8 C 16 : 20 D 24 : 36 E 56 : 84

Answer:

Q7) ( 2,-2)

Q8) (- 0.5 , -2)

Step-by-step explanation:

As we have to find the mid-points of the line segments, the line segments will be divided in same ratio i.e. 1:1 (∵ A Mid-point divides a line segment into equal parts )

According to Section formula ,

[tex]( x' , y') = (\frac{mx^2 + nx^1}{m+n} , \frac{my^2+ny^1}{m+n} )[/tex]

where (m,n) are the ratios in which a line segment is divided & ( x¹ , y¹ ) ( x², y²) are the co-ordinates of a line segment.

In Q7 ,

x¹ = 3 , y¹ = -9 , x² = 1 , y² = 5 & m = n = 1

So putting the section formula here gives :-

[tex]( x' , y') = (\frac{1*1 + 1*3}{1+1} , \frac{1*5+1*(-9)}{1+1} ) = ( 2 , -2)[/tex]

In Q8 ,

x¹ = 5 , y¹ = -1 , x² = -6 , y² = -3

So putting the section formula here gives :-

[tex](x' , y') = (\frac{1*(-6) + 1*5}{1+1} , \frac{1*(-3) + 1*(-1)}{1+1}) = ( -0.5 , -2)[/tex]

Answer:

64$

Step-by-step explanation:

Ifshe saved 8$ each week then that would equal to 40

But by adding the 24$ already saved the total amount would equal to 64$

Answer:

35

Step-by-step explanation:

If I am not correct I'm sorry.

If Ryan can eat 14 hot dogs in 6 min then he should be able to eat about 35 hot dogs in 15 mins.

14/6= 2.333...

so 2.333... x 15 would equal 35

I hope this helps.

Answer:

Ryan can eat about 34.5  hot dogs in 15 minutes

Step-by-step explanation:

You first need to find how many hot dogs ryan eats in one minute. By doing this you need to do 14 divided by 6 and that will get you to 2.3

Than you need to take that 2.3 and muliply it by the 15 minutes and than that would get you to your answer of 34.5 hotdogs in 15 minutes

I hope this helped!

Answer:

4xy and 12x

Step-by-step explanation:

In this question, we are to select which of the options to put into the blank space that will make the greatest common factor of the polynomial 2x. We are to select two options

Now, looking at the blank space, we should understand that , any answer we shall be choosing shall be an answer that contains x alongside the number.

This makes 24 and 44y out of the way.

Now let’s look at 4xy and 12x. Let’s insert them into the blank space;

36x^3-22x^2 - 4xy which gives : 2x(18x^2-11x-2y)

and 36x^3-22x^2-12x = 2x(18x^2-11x-6)

The reason why we will not use 44y and 24 is because 2x is not a factor of either.

Answer:

Answer:4xy and 12x

Step-by-step explanation:

The could both be a product of 2x

Answer  -1/12

Step-by-step explanation:

-7/12 + 1/2 cannot be added until you change 1/2 into 6/12.

To change 1/2 to 6/12, you have to multiply 1/2 by 6 because you want the same denominator. Since you can't just make a whole new fraction by changing the denominator, you have to multiply the numerator by 6 as well.

After changing the fraction, you should get -7/12 + 6/12.

now you can just add the numerators and denominators together and get -1/12!

Answer:

The answer is

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

C(-3,-1), Q(-2,3)

The distance between them is

[tex] |CQ| = \sqrt{ ({ - 3 + 2})^{2} + ( { - 1 - 3})^{2} } \\ = \sqrt{ ({ - 1})^{2} + ( { - 4})^{2} } \\ = \sqrt{1 + 16} \\ = \sqrt{17} \: \: \: \: \: \: \: \\ = 4.1231...[/tex]

We have the final answer as

[tex] \sqrt{17} \: \: \: or \: \: \: 4.12 \: \: \: \: units[/tex]

Answer:

z=3

Step-by-step explanation:

2(2z -4)=4

Divide by 2

2/2(2z -4)=4/2

2z-4 = 2

Add 4 to each side

2z-4+4 = 2+4

2z = 6

Divide by 2

2z/2 = 6/2

z=3

Answer:

Step-by-step explanation:

No there is no difference because in a decimal the zero's don't matter, they can go on infinitely but if the numbers above zero are the same and in the same order then the zero's don't make any difference.

I need help

Step-by-step explanation:

Step-by-step explanation:

2(2x - 6) + 2(x + 3) = 26

4x - 12 + 2x + 6 = 26

4x + 2x -12 + 6 = 26

6x - 6 = 26

6x = 26 + 6

6x = 32

x =32/6

x = 5.3333

Answer:

Step-by-step explanation:

2(2x -6) + 2(x + 3) = 26

4x - 12 + 2x + 6 = 26

6x - 6 = 26

6x = 32

x = 32/6= 16/3

Answer:

1/20

Step-by-step explanation:

3/10 - 1/4

First, convert the fractions to a common denominator:

3/10 *2/2 = 6/20

1/4 * 5/5 = 5/20

Now put them back into the equation and solve:

6/20 - 5/20 = 1/20

Another way to do this:

3/10 - 1/4

Convert the fractions into decimals:

3/10 = 0.3

1/4 = 0.25

substitute back into the equation and solve:

0.3 - 0.25 = 0.05

convert back into fractions:

0.05 = 1/20

Answer:

Mass of proton (m) = 1.67×10^(-27) kg

Step-by-step explanation:

Mass of proton (m) = 1.67×10^(-27) kg.

Since, 1 kg = 1000 g

Therefore, m = 1.67x10^(-27+3) g = 1.67x10^(-24) g

Let N no. of protons be present in 1 g. Hence, Nxm = 1 g

So, N = 1 / m = 1 / (1.67x10^(-24))

N = 6x10^(23) (approx.)

Exact mass of proton gives N = 6.022 x 10^(23).

That is a very special no. In fact, it is the Avogadro’s constant used frequently in chemistry. Avogadro’s no. is actually the number of atoms in exactly 12 g of C-12 isotope of carbon. Since, the atomic mass of C-12 is 12 u (unified mass), then again the no. of carbon atoms turn out to be N.

Answer:

V is the variable

Step-by-step explanation:

Answer:a. v

Step-by-step explanation:

Given

Required

Identify the variable

Literary, variable means things that change in values;

Going by this definition, we have that:

3 -> This is not a variable because its value will always be 3

v -> This is a variable because its value can change once its value changes, the result of the expression will also change

- -> This is not a variable; it is an arithmetic operator to subtract

8 -> This is not a variable because its value will always be 8

Take for instance

When  

Notice that there's a difference in both results;

This is as a result of v being a variable

Step-by-step explanation:

Answer:

since F is midpoint

DF= FE = 2x+6

DF +FE=DE

2x+6 + 2x+6 = 2x+36

4x + 12 = 2x+36

2x = 24

x=12

DE =2x+36 =2*12 + 36 = 60
