Answer:

The main purpose of America's Declaration of Independence was to explain to foreign nations why the colonies had chosen to separate themselves from Great Britain. The Revolutionary War had already begun, and several major battles had already taken place.

Step-by-step explanation:

The shaded region in the graph represent all possible solution set for [x] and [y].

Given is the inequality as -

- 5x + 4y > - 7

Refer to the graph attached. The shaded area represents the total set of possible solutions for [x] and [y] respectively.

Therefore, the shaded region in the graph represent all possible solution set for [x] and [y].

Answer:

x=2

Step-by-step explanation:

1. AB=AC (The triangle is isosceles. This means that at least two of its sides are equal in length. Looking at the triangle in the picture, sides AB and AC look the same, so we will assume that they are equal. Note that as you get more advanced, assuming isn't the best strategy. You should always try to look for hints if you are ever unsure. For example, if there are two angles that are the same measure in a triangle, the two sides that are only touching one of these angles are equal in length. This is called the base angles theorem converse.)

2. 9x-3=6x+3 (Rewrite sides AB and AC as the values given in the picture. This is called substitution.)

3. 9x=6x+6 (Add 3 to each side)

4. 3x=6 (Subtract 6x from each side)

5. x=2 (Divide each side by 3)

Answer:

[tex]5x-4y+4=0[/tex]

Step-by-step explanation:

Given: A point  which is perpendicular to the line .

To find: The equation of the line which passes through [tex](-4, -4)[/tex] and is perpendicular to the line [tex]4x+5y=5[/tex].

Solution:

We have, [tex]4x+5y=5[/tex].

Slope of the line [tex]4x+5y=5[/tex] is [tex]-\frac{4}{5}[/tex].

The line which passes through [tex](-4, -4)[/tex] is perpendicular to the line [tex]4x+5y=5[/tex].

Now, the product of the slopes of two perpendicular lines is [tex]-1[/tex].

Therefore, [tex]m\times-\frac{4}{5}=-1[/tex]

So, its slope is [tex]\frac{5}{4}[/tex].

Now, the equation of the line which passes through [tex](-4, -4)[/tex] and slope [tex]\frac{5}{4}[/tex] is:

[tex]y-(-4)=\frac{5}{4} [x-(-4)][/tex]

[tex]\Rightarrow y+4=\frac{5}{4} (x+4)[/tex]

[tex]\Rightarrow 4(y+4)=5(x+4)[/tex]

[tex]\Rightarrow 4y+16=5x+20[/tex]

[tex]\Rightarrow 5x-4y+20-16=0[/tex]

[tex]\Rightarrow 5x-4y+4=0[/tex]

Hence, the equation of the line that contains the point [tex](-4, -4)[/tex] and is perpendicular to the line [tex]4x+5y=5[/tex] is [tex]5x-4y+4=0[/tex].

Answer:

0.56 inches from the vertex of the canvas

Step-by-step explanation:

Golden ratio can be interpreted as

B / A = ( A + B ) / B ----- (  1  )

A = smaller side = 12 inches

B = larger side  = 16 inches

Back to equation 1

16 / 12 = ( 16 + 12 ) / 16

4 / 3 ≠ 7 / 4

The Golden ratio can not be applied because the rule is not obeyed  

The focal point can be determined as :

( longest width / 2 )= 12 / 2 = 6^ 2 = 36 ---- 2

(4* depth) = 16 * 4 = 64 ---- 3

hence the focal point ( 2 / 3 ) = 36 / 64 = 0.56 inches from the vertex of the canvas

Step-by-step explanation:

Answer:

x=-20

Step-by-step explanation:

3x-11=4x+9

3x=4x+20

x+20=0

x=-20

Answer:10 liter * 20%= x liter*40% + (10- x) liter*5%

10l * 20%= x liter * 35% + 10 liter*5%

x liter *35 = 10l * 20 - 10l *5= 10l*15

x liter = 10l *15/35= 4.28 L= 4.3L

The volume of 40% solution= 4.3L

The volume of 5% solution= 10L- 4.3L= 5.7L

Step-by-step explanation:

In this question, you want to make 10 liters 20% concentration solution by mixing 5% and 40% concentration. There should be multiple answers to this question. Assuming that the total volume of 5% and 40% solution equal to 10L(no solution wasted), then you can determine the volume of solution needed. The formula should be:

Answer:

1/2 din 5 €

Step-by-step explanation:

Opțiunea 1

1/4 din 5 €

= 1/4 × 5 €

= 1,25 €

Opțiunea 2

1/2 din 5 €

= 1/2 × 5 €

= 2,5 €

Prin urmare, opțiunea care ar însemna mai mulți bani este 1/2 din 5 €

Answer:

A. (-5, 1.5)

Step-by-step explanation:

Answer:

The answer is 5 beecause coefficients are the number when you multiply a number and a variable. For example 5a the coefficient in that term is 5 if you have 48e the coefficient is 48. So the coefficient is the number when you multiply a number times a variable.

Answer:

363/8π yd²

Step-by-step explanation:

The total area of the circle = πr²

the area of the shaded region = 135/360 × πr² = ⅜ πr² = ⅜ π × 11² = 363/8 π ≈ 136.125 yd²

Answer:

$6

Step-by-step explanation:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

there's 10

1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15

1 + 9 = 10

10 + 10 = 20

2, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15

2 + 8 = 10

20 + 10 = 30

3, 4, 5, 6, 7, 11, 12, 13, 14, 15

3 + 7 = 10

30 + 10 = 40

4, 5, 6, 11, 12, 13, 14, 15

4 + 6 = 10

40 + 10 = 50

5, 11, 12, 13, 14, 15

5 + 15 = 20

50 + 20 = 70

11, 12, 13, 14

11 + 14 = 25

70 + 25 = 95

12, 13

12 + 13 = 25

95 + 25 = 120

she would 120 nickels which is

120 x 5 = 600 cents or $6

Answer:

Step-by-step explanation:

Width =x

Length = 2*x = 2x

Diagonal = 5√5

Use Pythagorean theorem

Length² + Width² = diagonal²

  (2x)²    + x²        = (5√5)²      

{[tex](5\sqrt{5})^{2}=5\sqrt{5} *5\sqrt{5}=5*5*\sqrt{5*5}=25*5=75[/tex]}

     4x²   + x²        = 75

                      5x² = 75

                        x²  = 75/5

                       x²   = 15

                        x = √15

Width = √15

Length = 2√15

Area of rectangle = length *width

                             = √15 *2√15

                             [tex]= 2* \sqrt{15*15}\\\\= 2*15\\= 30[/tex]

                             = 30 square units
