What is the total surface area of the rectangular prism?

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.

[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]

In the first question firstly, We will find the volume of the hemisphere with a diameter of 8 cm.

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]134.09 cm^{3}[/tex].

Now we will find the volume of the inverted cone with the formula,[tex]\pi r^{2}h/3[/tex].

Which gives [tex]50.28 cm^{3}[/tex].

Adding both give [tex]184.57 cm^{3}[/tex].

Rounding [tex]184 cm^{3}[/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:

Step-by-step explanation: use a protractor and make a dot in the hole in the center of the line in the protractor. then find 55 on the protractor and draw a straight line from the dot you made to the number 55. if there are no numbers on the protractor, then draw a right angle (90 degrees) and draw a line through it. (45 degrees). Then draw a line through the middle of it, but make it closer to 45 degrees. (You can draw more placement lines if it helps you)

Answer:

Step-by-step explanation:

As 55 is not divisible by 15, we cannot construct 55 degree angle with the help of a compass or a ruler.

So, we need to use the protractor.

Here's how:

Step 1: Draw a random line.

Step 2: Place Protractor on the line as shown.

Step 3: Point the 55 degrees

Step 4: Draw a line towards it.

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 $(1, 4)$.
