Answer:

Throw a die

Every number on the die represents one of the 6 prizes

The amount of times you throw the die describes the number of boxes you need.

Answer:

Here we assume that each prize has the same probability to be in a box.

You can model this with a 6 side dice.

Assign each number of the dice to one different prize, then roll the dice and record the number, each roll corresponds to one box of cereal, and the number means that you get that price. When the 6 different numbers in the dice showed up, means that you got all the prices. Now, the total number of rolls that you needed to get the 6 numbers will be equivalent to the number of boxes that you need to buy in order to get the 6 prizes.

33. Suppose you were on a planet where the

tatyana61 [14]

Answer:

a) 3.675 m

b) 3.67m

Explanation:

We are given acceleration due to gravity on earth = $9.8ms^-2$

And on planet given = $2.0ms^-2$

A) Since the maximum jump height is given by the formula

$\mathrm{H}=\frac{\left(\mathrm{v} 0^{2} \times \sin 2 \emptyset\right)}{2 \mathrm{g}}$

Where H = max jump height,

v0 = velocity of jump,

Ø = angle of jump and

g = acceleration due to gravity

Considering velocity and angle in both cases

$\frac{\mathrm{H} 1}{\mathrm{H} 2}=\frac{\mathrm{g} 2}{\mathrm{g} 1}$

Where H1 = jump height on given planet,

H2 = jump height on earth = 0.75m (given)

g1 = 2.0 $ms^-2$ and

g2 = 9.8 $ms^-2$

Substituting these values we get H1 = 3.675m which is the required answer

B) Formula to find height of ball thrown is given by

$\mathrm{h}=(\mathrm{v} 0 * \mathrm{t})+\frac{\mathrm{a} *\left(t^{2}\right)}{2}$

which is due to projectile motion of ball

Now h = max height,

v0 = initial velocity = 0,

t = time of motion,

a = acceleration = g = acceleration due to gravity

Considering t = same on both places we can write

$\frac{\mathrm{H} 1}{\mathrm{H} 2}=\frac{\mathrm{g} 1}{\mathrm{g} 2}$

where h1 and h2 are max heights ball reaches on planet and earth respectively and g1 and g2 are respective accelerations

substituting h2 = 18m, g1 = 2.0 $ms^-2$ and g2 = 9.8 $ms^-2$

We get h1 = 3.67m which is the required height

Write an expression to find the perimeter of the rectangle below: 2x - 3y 3x - 1

LuckyWell [14K]

Answer:

2(5x-3y-1)

Step-by-step explanation:

perimeter of a rectangle formula:

2l+2w

l=length(2x-3y)5x

w=width(3x-1)

2(2x-3y)+2(3x-1)

4x-6y+6x-2

10x-6y-2

2) all of these numbers have a gcf of 2 so lets divide this equation by 2:

2(5x-3y-1)

hope this helps!

What is the justification for each step in the

Leviafan [203]

To get from 7-10=2(-3+8) to 7-10=-6+16, you have to use the distributive property because of the parenthesis. the next step would be adding 10 to both sides in order to even the equation (adding because it cancels out the negative and makes 0), and the last step you have is adding 6 to both sides of the equation to balance it. in order to get 2, you have to divide 26 by 13 (26/13). hope this helps!
