Answer:

$\frac{4}{9}$

Step-by-step explanation:

There are 3 types of vacation and 3 lengths of time.

Only ski resorts have snow so the probibility of no snow is $\frac{2}{3}$

The probability of at least 6 days is $\frac{2}{3}$ , multiply the two displayed numbers to get:

$(\frac{2}{3})^2\\ =\frac{2}{3}*\frac{2}{3} \\=\frac{4}{9}$

Just need the equation

Anna007 [38]

$a. $ x = -2\\b. $ x = \frac{3}{2} \\c. $ x = 0\\d. $ x = -\frac{1}{5}$

Each of the equations can be solved as shown below:

a. $3x + 7 = - x - 1$

$3x + 7 + x = - x - 1 + x$ (addition property of equality)

$4x + 7 = - 1\\4x + 7 - 7 = -1-7$ (Subtraction property of equality)

$4x = -8\\\frac{4x}{4} = \frac{-8}{4}$ (Division property of equality)

$x = -2$

b. $1 - 2x + 5 = 4x - 3\\$

Add like terms

$6 - 2x = 4x - 3\\\\6 - 2x - 6 = 4x - 3 - 6$ (Subtraction property of equality)

$- 2x = 4x - 9\\-2x - 4x = 4x -9 - 4x$ (Subtraction property of equality)

$-6x = -9 \\\frac{-6x}{-6} = \frac{-9}{-6}$ (Division property of equality)

$x = \frac{3}{2}$

c. $4x - 2 + x =-2 + 2x\\$

$5x - 2 = -2 + 2x\\5x - 2x = -2 + 2\\3x = 0\\ x = \frac{0}{3} \\x = 0$

d. $3x - 4 + 1 = - 2x -5 + 5x\\$

$3x - 3 = - 7x -5\\3x + 7x = 3 - 5\\10x = -2\\x = \frac{-2}{10} \\x = -\frac{1}{5}$

The value of x in each equation are:

$a. $ x = -2\\b. $ x = \frac{3}{2} \\c. $ x = 0\\d. $ x = -\frac{1}{5}$

The school band is selling raffle tickets for $2. If Kyle spent p dollars on tickets this week and q dollars on tickets the week

Alex

Answer:

Tickets = p/2 + q/2

Step-by-step explanation:

I don't understand the options, as written.

The answer should be Tickets = p/2 + q/2

If q = 10 and p = 20, Kyle would have bought 5 tickets the week before, and 10 tickets this week.

Angle x is such that sin x = a + b and cos x = a − b, where a and b are constants.

Mazyrski [523]

Answer:

Step-by-step explanation:

sin x=a+b

cos x=a-b

sin²x+cos²x=(a+b)²+(a-b)²=2a²+2b²

or 2a²+2b²=1

a²+b²=1/2 which is constant for all values of x

(ii)

$\frac{\sin x}{\cos x}=\frac{a+b}{a-b}\\\tan x=\frac{a+b}{a-b}=2\\a+b=2a-2b\\b+2b=2a-a\\or a=3b$

Help solving this Math problem

Paha777 [63]

1. Formula for volume of a cone is: V = PI * r * h/3

Volume = PI * 1 * 5/3 = 5.24 cubic inches.

2. Formula for volume of a sphere is: V = 4/3 * PI * r^3

Volume = 4/3 * PI * 1^3 = 4.19 cubic inches.
