Step-by-step explanation:

<h3>this is given that the figure is a hexagon</h3><h3>let give a name to the given hexagon be ABCDEF</h3>

<h3>Angle a + B + C + D = 720 ( Ls sum pro. of hexagon)</h3><h3>3x-20+3x-20+4x+4x+3x-20+3x-20 = 720</h3><h3>3x+3x+3x+3x+4x+4x-20-20-20-20 = 720 (rearranging)</h3><h3>20x - 80 = 720</h3><h3>20x = 720 + 80 </h3><h3>x=800/20</h3>

<h2>x = 40 degrees </h2>

Sveta_85 [38]

Answer:

$\huge\boxed{1000 \ \text{cm}^3}$

Step-by-step explanation:

There are two ways we can solve this equation.

<h2>A) Using the formula provided</h2>

The formula provided states that the volume of a cube based on the area of one of it's faces will be $a^{\frac{3}{2}}$ , a the area of one face. Since we know the area of one face, we can substitute that inside the equation.

$100^{\frac{3}{2}}$

It's important to note that when we have a number to a fraction power, it's the same as taking the denominator root of the base to the numerator power.

So - $100^{\frac{3}{2}}$ becomes $\sqrt{100^3}$

$100^3=1000000$

$\sqrt{1000000}=1000$

Therefore, the volume of this cube will be $1000 \ \text{cm}^3$

<h2>B) Using prior knowledge about cubes</h2>

We can additionally use prior knowledge to find the volume of this cube.

We know that the area of a square will be $s^2$ , where s is the length of a side. We also know the formula to find the volume of a cube from it's side length is $s^3$ .

Since we know that one face is 100, we can make an equation - $s^2=100$

$\sqrt{s^2}=\sqrt{100}$
$s=10$

Now that we know the value of s, we can plug it into the volume formula, $s^3$ .

$10^3$
$10 \cdot 10 \cdot 10$
$1000$

So the volume is $1000 \ \text{cm}^3$ .

Hope this helped!

Aysha’s score for a game is given by the expression 9 − 8.2 − (−1.9).

11Alexandr11 [23.1K]

Answer:

Aysha

Step-by-step explanation:

Aysha's score = 9 – 8.2 = 0.8 + 1.9 = 2.7

Beth's score = –8 + 5.4 = (–2.6) – 1.8 = – 4.4

2.7 > (– 4.4)

Please tell the function equation as well too

Usimov [2.4K]

Answer:

A= Rate of change is y=4x, this is because it is set up as y/x and for the graph B= y=3x. Function A is greater in change than Function B because if you substitute x for 1, A would be 4 and B would be 3.

Answer:

1.67 m, 8.33 m

Step-by-step explanation:

If the ratio of lengths is 1 : 5, then the ratio of the shortest length to the total is ...

1 : (1+5) = 1 : 6

The shortest length is (10 m)×(1/6) = 1.67 m. The longer length is 10 -1.67 = 8.33 m.

The lengths of the pieces are 8.33 m and 1.67 m.
