Juan wants to make a new game board that is a grid containing 25 equally sized squares. How many squares should be shaded to cre

pickupchik [31]

Let the number of shaded square be x. And it is given that total number of squares are 25.

$probability = \frac{shaded \ squares}{total \ squares}$

Substituting the values

$0.2 = \frac{x}{25}$

Performing cross multiplication

$0.2*25=x \\ x = 5$

So 5 squares should be shaded to create a region with a geometric probability of 0.2 .

Answer:

264 ft³

Step-by-step explanation:

The following data were obtained from the question:

Pi (π) = 3.14

Height (h) = 21 ft

Radius (r) = 2 ft

Volume (V) =..?

The volume of the cylinder can be obtained as follow:

V = πr²h

V = 3.14 × 2² × 21

V = 3.14 × 4 × 21

V = 264 ft³

Therefore, the of the cylinder is 264 ft³

Solve each system by substitution 2x + y = 20 and 6x - 5y = 12

ivolga24 [154]

$\huge\mathbf{Answer࿐}$

$\underline{ \underline{ \bf{step} - 1}}$

Taking first equation,

$2x + y = 20$

$y = 20 - 2x$

$\underline{ \underline{ \bf{step} - 2}}$

plugging the value of y in second equation,

$6x - 5y = 12$

$6x - 5(20 - 2x) = 12$

$6x - 100 + 10x = 12$

$16x = 12 + 100$

$x = \dfrac{112}{16}$

$x = 7$

$\underline{ \underline{ \bf{step} -3}}$

plugging the value of x in first equation,

$2x + y = 20$

$(2 \times 7) + y = 20$

$14 + y = 20$

$y = 20 - 14$

$y = 6$

<h2>Conclusion :</h2>

$x = 7$
$y = 6$
