Answer:

116 km squared

Step-by-step explanation:

When you get crazy shapes like this, try and look for the basic ones inside (i.e. triangles, rectangles, etc.) I can find one big triangle and two rectangles, one small and one larger. Vide the attatchment for reference.

Step 1. Find the missing variables, x, y, and z

y = 2

x = 6 - 2 = 4

z = 8 + (4) + 2 = 14

Step 2. Find the area of each shape

Triangle:

Area = bh/2 = (8 x 14)/2 = 56 km sq

Big rectangle:

Area = bh = 8 x 6 = 48 km sq

Small rectangle:

Area = bh = 2 x 6 = 12 km sq

Step 3. Add all the areas together

56 + 48 + 12 = 116 km sq

I hope this helps!

You want to go to laser tagging but would like to find out which place has the better deal laser flash charges an initial fee of

mariarad [96]

Answer:

The cost at both Laser Flash and Laser storm would be the same after 4 games

Step-by-step explanation:

Let the number of games be represented as x

Laser flash charges an initial fee of $16 for gear and $4 per game

For Laser flash , the Equation is:

$16 + $4 × x

y= 16 + 4x

Laser storm charges an initial fee of $20 for gear and $3 per game

$20 + $3 × x

y = 20 + 3x

Hence: Equating both costs to each other

Laser flash = Laser Storm

16 + 4x = 20 + 3x

Collect like terms

4x - 3x = 20 - 16

x = 4 games

The cost at both Laser Flash and Laser storm would be the same after 4 games

Xavier, Yvonne, and Zelda each try independently to solve a problem. If their individual probabilities for success are 1/4, 1/2

siniylev [52]

Answer: The probability that Xavier and Yvonne can solve a problem but Zelda cannot is $\frac{3}{64}$

Step-by-step explanation:

We are given:

Probability of success of Xavier, $P(S)_{Xavier}=\frac{1}{4}$

Probability of failure of Xavier, $P(F)_{Xavier}=1-\frac{1}{4}=\frac{3}{4}$

Probability of success of Yvonne, $P(S)_{Yvonne}=\frac{1}{2}$

Probability of failure of Yvonne, $P(F)_{Yvonne}=1-\frac{1}{2}=\frac{1}{2}$

Probability of success of Zelda, $P(S)_{Zelda}=\frac{5}{8}$

Probability of failure of Zelda, $P(F)_{Zelda}=1-\frac{5}{8}=\frac{3}{8}$

We need to calculate:

The probability that Xavier and Yvonne can solve the problem but Zelda cannot, we use:

$P(S)_{Xavier}\times P(S)_{Yvonne}\times P(F)_{Zelda}=\frac{1}{4}\times \frac{1}{2}\times \frac{3}{8}=\frac{3}{64}$

Hence, the probability that Xavier and Yvonne can solve a problem but Zelda cannot is $\frac{3}{64}$

My friend joop got 14 totts and elentines for about $72. Totts for $8 each and some elentines for $3 each.

STatiana [176]

Answer:

x +y = 14
8x +3y =72

Step-by-step explanation:

The variables are defined, so we only need to express the given relations. The total of the two quantities is 14.

x + y = 14

The sum of costs is $72. Totts are $8 each, so x of them will cost 8x. Elentines are $3 each, so y of them will cost 3y.

8x +3y = 72
