Question : A square game board is divided into smaller squares, each with sides one-ninth the length of the sides of the board.

bagirrra123 [75]

Answer:

Therefore the game board is divided into 81 smaller squares.

Step-by-step explanation:

Given that, there is a square game.

Consider x be length of one side the square.

The volume of the square is = side ×side

=x² square units

Since the length of side of smaller square is one-ninth of the game board.

Then one side length of the smaller square is $\frac19x$ units.

The area of a smaller square is $=(\frac19x)\times (\frac19x)$

$=\frac{1}{81}x^2$

Let a number of square is formed from the game board.

a ×The area of one smaller square= The area of game board.

According to the problem,

$a\times (\frac{1}{81}x^2)=x^2$

$\Rightarrow a =\frac{x^2\times 81}{x^2}$

$\Rightarrow a= 81$

Therefore the game board is divided into 81 smaller squares.

HELP PLZ!!!!- In 2012, on average, about 9.46 × 10^-1 pound of potatoes was produced for every 2.3 × 10^-5 power acre harvested.

sashaice [31]

Answer: The answer is 41.13 pounds (approx.).

Step-by-step explanation: Given that the average production of potatoes in 2012 was 0.946 pounds for every 0.000023 power acre harvested. We need to calculate the pounds of potatoes produced on average for each acre harvested.

For that, we need to divide the pounds of potatoes by number of acres harvested.

In 0.000023 acre harvested, ponds of potatoes = 0.946 ponds.

Therefore, in 1 acre harvested, pounds of potatoes is given by

$p=\dfrac{0.946}{0.000023}=41.13~\textup{(approx.)}$

Thus, the answer is 41.13 pounds (approx.).

What is the value of b in the triangle shown below?

Akimi4 [234]

Answer:

b= 4 in.

Step-by-step explanation:

Ok. So the area of a triangle is base * height divided by 2.

So, the base is b and the height is 3b.

b*3b= 3b^2.

Now, divide that by 2.

(3b^2)/2.

Now, we know what the area is already- 24 in.^2. So, let's set the area expression that I found earlier equal to this area, since they're the same.

(3b^2)/2 = 24

3b^2 = 48

b^2 = 16

Ok. Let's stop here. Now, we square root both sides to obtain b, but we are presented with a problem here. B can equal both 4 and -4 right? Since -4*-4=16 and 4*4=16. However, it is impossible for a 2d shape to have negative measurements. So, the answer is 4.
