Step-by-step explanation: Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

Answer:

- 4y - 7

Step-by-step explanation:

We know that,

( - ) × ( - ) = ( + )

( - ) × ( + ) = ( - )

( + ) × ( + ) = ( + )

Accordingly, let us solve the above expression.

- 4y - 4 + ( - 3 )

Solve the brackets.

- 4y - 4 - 3

Combine like terms.

- 4y - 7

Answer:

[tex] \sf \: -4y - 7 [/tex]

Step-by-step explanation:

Now we have to,

→ Simplify the given expression.

The expression is,

→ -4y - 4 + (-3)

Let's simplify the expression,

→ -4y - 4 + (-3)

→ -4y - 4 - 3

→ -4y - (4 + 3)

→ -4y - (7)

→ -4y - 7

Hence, the answer is -4y - 7.

Answer:

The vertex of the graph of the equation $y = 3x^2 - 6x + 7$ is the point $(1, 4)$.

Step-by-step explanation:

The vertex of the graph of a parabolic function $y = ax^2 + bx + c$ is given by the formula:

$x = \frac{-b}{2a}$

where a, b, and c are constants and x is the x-coordinate of the vertex.

For the given equation $y = 3x^2 - 6x + 7$, we have a = 3, b = -6, and c = 7. So, we can use the formula to find the x-coordinate of the vertex:

$x = \frac{-b}{2a} = \frac{-(-6)}{2(3)} = \frac{6}{6} = 1$

So, the x-coordinate of the vertex is 1. To find the y-coordinate, we substitute the value of x back into the original equation:

$y = 3(1)^2 - 6(1) + 7 = 3 - 6 + 7 = 4$

So, the vertex of the graph of the equation $y = 3x^2 - 6x + 7$ is the point $(1, 4)$.

Answer:

[tex]\huge\boxed{\sf Area = 32 \ ft.^2}[/tex]

Step-by-step explanation:

Given that, the space is triangular.

So,

[tex]\displaystyle Area \ of \ triangle = \frac{1}{2} (Base)(Height)[/tex]

Here,

Base = b = 10 ft.

Height = h = 6.4 ft.

So,

[tex]\displaystyle Area = \frac{1}{2} (10)(6.4)\\\\Area = (5)(6.4)\\\\Area = 32 \ ft.^2\\\\So, she \ needs \ a \ carpet \ of \ 32 \ ft.^2\ to \ cover \ the \ area.\\\\\rule[225]{225}{2}[/tex]

Answer:

Question #1: 17 Miles

Question #2: 10 units

Step-by-step explanation:

Question #1: Here we are using the Pythareom Theorem [tex]\sqrt{a^{2}+b^{2} } =c^{2}[/tex]

We must plug in the horizontal distance (x) from a to c (-4 to 4 = 8).

Then we take the vertical distance (y) from a to c (-6 to 9 = 15).

Plug it all into the Pythareom Theorem[tex]\sqrt{8^2+15^2} =17[/tex]

In the second question firstly, We will find the volume of the hemisphere with a radius of 3cm.

we will find the volume of the hemisphere by using the formula that is,    [tex]2\pi r^{3} /3[/tex].

Which gives us, [tex]56.57 cm^{3}[/tex].

Now we will find the volume of the cylinder with the formula, [tex]\pi r^{2}h[/tex].

Which gives [tex]132 cm^{3}[/tex].

Adding both give [tex]188.57 cm^{3}[/tex].

In the last question, we will find the volume of the cone with a radius and height of 7ft.

We will find the volume of the cone by using the formula that is, [tex]\pi r^{2}h/3[/tex].

Which gives us, [tex]102.66ft^{3}[/tex].

Now we will find the volume of the cylinder with the formula, [tex]\pi r^{2}h[/tex].

Which gives [tex]132ft^{3}[/tex].

Adding both give [tex]234.66ft^{3}[/tex].

Answer:

The original data set:

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

Finding the median:

77 and 82 are the 2 middle numbers

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

Do 77 + 82 which equals 159

Then do 159 ÷ 2 which would be 79.5

The median for the original data set would be 79.5

Then adding the 60° would make a new data set:

57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

The middle number would be 77

57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

So the median for the second data set would be 77.

Answer:

16 inches

Step-by-step explanation:

We can use the Pythagorean theorem to find the height of the television. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two smaller sides is equal to the square of the length of the longest side (the hypotenuse). In this case, the diagonal of the television is the hypotenuse and the width and height are the other two sides.

So, we can set up the equation as follows:

a^2 + b^2 = c^2

where a is the width (22 inches), b is the height, and c is the diagonal (27 inches).

We can solve for b:

b^2 = c^2 - a^2

b^2 = 27^2 - 22^2

b^2 = 729 - 484

b^2 = 245

b = √245

b = 15.56 inches (rounded to two decimal places)

So, the height of the television to the nearest inch is 16 inches.

Step-by-step explanation:

Answer: hope this helps ♡      (i wont mind getting brainliest )

x = 3

Step-by-step explanation:

z° and 89° are two opposite angles.

z° = 89°

89° + 89° + (11x + 58)° + (11x + 58)° = 360° (adds up to 360° coz its a circle)

178° + (11x + 58)° + (11x + 58)° = 360°

178° + 58° + 58° + (11x + 11x)° =  360°

178° + 116° + 22x° =  360°

294° + 22x° = 360°

294° - 294° + 22x° = 360° - 294°

22x = 66

22x ÷ 22 = 66 ÷ 22

x = 3

(double check: 11×3 = 33    2×(33+58)+178=360° ✓)

Answer:

40.5 inches

Step-by-step explanation:

I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.

Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.

February and March combined: 8.5+5.1 = 13.6

Since the question asked how much more, that means you subtract:

26.9 - 13.6 = 13.3

hope this helped =)
