Answer:

change it to a mix fraction instead

Step-by-step explanation:

Answer:

You add a one underneath of the while number So for example if the number was 2 make it into a fraction 2/1 then flip it so you can multiply it

Answer:

k = - 2

Step-by-step explanation:

( 2x - y )²

Formula : -

( a - b )² = a² + b² - 2ab

Here,

a = 2x

b = y

( 2x - y )²

= ( 2x )² + y² - 2 ( 2x ) ( y )

= 4x² + y² - 4xy

So,

( 2x - y )² = 4x² + y² - 4xy

( 2x + y )²

Formula : -

( a + b )² = a² + b² + 2ab

Here,

a = 2x

b = y

( 2x + y )²

= ( 2x )² + y² + 2 ( 2x ) ( y )

= 4x² + y² + 4xy

So,

( 2x + y )² = 4x² + y² + 4xy

( 2x - y )² - ( 2x + y )²

= 4x² + y² - 4xy - ( 4x² + y² + 4xy )

= 4x² + y² - 4xy - 4x² - y² - 4xy

= 4x² - 4x² + y² - y² - 4xy - 4xy

= 0 + 0 - 8xy

= - 8xy

( 2x - y )² - ( 2x + y )² = 4xyk

- 8xy = 4xyk

Divide 4xy on both sides,

- 8xy / 4xy = 4xyk / 4xy

- 2 = k

k = - 2

Therefore, the value of k is - 2.

angle sum of triangle

180-112-48

There are two ways , so the first part reference to method 1 and and second part reference to method 2.

[tex] \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \tt In~\triangle ABC: [/tex]

[tex] \\ [/tex]

[tex] \tt \angle A + \angle B + \angle C = 180 {}^{ \circ} [/tex]

{sum of triangle}

[tex] \\ \\ [/tex]

here we can find value of angle C.

[tex] \\ [/tex]

[tex] \dashrightarrow \sf\angle A + \angle B + \angle C = 180 {}^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf112 + 48 + \angle C = 180 {}^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf160 + \angle C = 180 {}^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf\angle C = 180 {}^{ \circ} - 160 {}^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf\angle C =20^{ \circ} \\ [/tex]

[tex] \\ \\ [/tex]

angle c is congruent to angle f

.°. y = 20°

[tex] \\ \\ [/tex]

[tex] \\ \\ [/tex]

angle a = angle d

.°. value of x = 112°

Answer:

ok lets just solve each and see if its larger then 35

A) 5.94 × 6=35.64

B) 6.18 × 6=37.08

C) 7.03 × 5=35.15

D) 8.12 × 4=32.48

A,B&C

Hope This Helps!!!

Answer

Everyone except D

A's total is 35.64=Yes

B's total is 37.08=Yes

C's total is 35.15=Yes

D's total is 32.48=no so d is incorrect/

So your answers are A  B  C

Answer:

y=2x-7

2(2x-7)=4x-14

4x-14=4x-14

therefore,this has no solutions

Answer:

10

Step-by-step explanation:

The absolute value function always gives a positive value, that is

| - a | = | a | = a

Given

| 3f - 2g |  + 2 ← substitute f = - 2 and g = 1

= | 3(- 2) - 2(1) | + 2

= | - 6 - 2 | + 2

= | - 8 | + 2

= 8 + 2

= 10

Answer:

  3/10 lb

Step-by-step explanation:

The amount needed for a fraction of a pie is that fraction times the amount needed for the whole pie:

  (4/5) × (3/8 lb) = (4·3)/(5·8) lb = (3/5)(4/8) lb = 3/(5·2) lb

  = 3/10 lb

Mr. Anderson would need 3/10 pounds of apples for 4/5 of an apple pie.

Explanation:

Consider the point (1,2). If we apply the rule [tex](x,y) \to (-x,y)[/tex], then it would move to (-1,2).

The x coordinate flipped in sign from positive to negative. The y coordinate stays the same.

Another example is (-3,7) reflecting to (3,7).

Answer:

The rule is y = x - 9

n = 11

Step-by-step explanation:

To find patterns, we just have to look at the table and see if there are any repeating rules.

Well, the y values go from 1 to 3 to 6

3 - 1 = 2

6 - 3 = 3

Nothing similar there.

But, we can see that 10 - 1 = 9

12 - 3 = 9

When you subtract 9 from each x value, you get the y value

So, y = x - 9

n = 20 - 9

20 - 9 = 11

Ratio remains same

[tex]\\ \rm\rightarrowtail \dfrac{12}{3}=\dfrac{20}{n}[/tex]

[tex]\\ \rm\rightarrowtail 4=20/n[/tex]

[tex]\\ \rm\rightarrowtail n=20/4[/tex]

[tex]\\ \rm\rightarrowtail n=5[/tex]

Answer:

1)The dependent is the number of cars produced. The independent is the amount of time

2)I know that the number of cars produced is the dependent because it will change whenever the amount of time changes

3)This relationship is linear because as you get more time, you will get more cars

4)I could create a graph because I could plot down these points and find the slope

5) I would need a couple more points to plot                        

Answer:

[tex]\% = 53.8 \%[/tex]

Step-by-step explanation:

Given

[tex]Yes = 483[/tex]

[tex]No = 807[/tex]

[tex]Maybe = 210[/tex]

Required

Determine percentage of "No"

First, we need to determine the total population

[tex]Total= 483 + 807 + 210[/tex]

[tex]Total= 1500[/tex]

Percentage of No is then calculated as follows:

[tex]\% = \frac{No}{Total} * 100\%[/tex]

[tex]\% = \frac{807}{1500} * 100\%[/tex]

[tex]\% = \frac{80700}{1500} \%[/tex]

[tex]\% = 53.8 \%[/tex]

Answer:

7m² - 11m - 2

Step-by-step explanation:

(4m² - m + 2) - (-3m² + 10m + 4)

4m² + 3m² - m - 10m + 2 - 4

7m² - 11m - 2

Answer:

n=25

Step-by-step explanation:

Using the relation that describes the measure of the angle formed by two secants being equal to half of the difference of the 2 arcs (large arc-small arc) we can establish the relation;

[tex]10 = \frac{45 - n}{2} [/tex]

[tex]20 = 45 - n[/tex]

[tex] - 45 + 20 = - n[/tex]

[tex] - 25 = - n[/tex]

[tex]n = 25[/tex]
