3) Raeana is twice as old as Madeline, and Laura is 10 years older than Raeana.
If Laura is 50 years old, how old is Madeline? Let m represent Madeline's age in
years, and let r represent Raeana's age in years.

Answers

Answer 1

Answer:

M = 20; R = 40

Step-by-step explanation:

R = 2M

L = R + 10

L = 50

50 = R + 10

(Take away 10 from both sides)

50 - 10 = 40

40 = R

Remember, R = 2M

40 = 2M

(Divide both sides by 2)

40 / 2 = 20

20 = M

You have a bag of gummy worms. 12 are green, 3 are blue, 6 are red, and 2 are orange. What is the probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm?

Answers

Answer and working out attached. Hope it helps

The probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm:

What is probability?

Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.

Probability of Event = Favorable Outcomes/Total Outcomes = X/n

The probability of pulling a red worm from the bag is 6/(12+3+6+2) = 6/23.

After eating the red worm, there are 11 green worms left in the bag, so the probability of pulling a green worm is 12/(12+3+2) = 12/17.

To find the probability of both events occurring (pulling a red worm and then a green worm), we need to multiply their probabilities:

P(red and green) = P(red) × P(green)

P(red and green) = (6/23) × (12/17)

P(red and green) = 72/391

Therefore, the probability of reaching into the bag and pulling a red worm, eating it, and then pulling a green worm is 72/391.

Answer:

Step-by-step explanation:

Given

[tex]Flowers = 25x^2 + 5x + 5[/tex]

[tex]Unit\ price = 5x[/tex]

Required

The total price for 5 days

First, calculate the total for a day.

[tex]1\ day = Unit\ price * Flowers[/tex]

[tex]1\ day = 5x * (25x^2 + 5x + 5)[/tex]

Open bracket

[tex]1\ day = 125x^3 + 25x^2 + 25x[/tex]

For 5 days, the total will be.

Total = days * sales of a day

So, we have:

[tex]Total = 5 * [ 125x^3 + 25x^2 + 25x][/tex]

[tex]Total = 625x^3 + 125x^2 + 125x[/tex]

(2) Parv has a $50 gift card. He uses the gift card to buy a pack of games
for $9.99. He also wants to buy some movies (n). Each movie costs
$3.99. Which inequality describes how many movies Parv can buy?

Answers

Answer:

$50 - $9.99 = $40.01

$40.01 ÷ $3.99 = 10

so the answer is 10

Step-by-step explanation:

if thats not whats being asked sorry

Inequality shows a relationship between two numbers or two expressions.

The inequality describes the number of movies Parv can buy.

9.99 + 3.99x ≤ 50

Where x is the number of movies.

The number of movies Parv can buy is 10.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal= ≥

We have,

Gift card = $50

Cost of a pack of games = $9.99

Cost of each movie = $3.99

x = number of movies

The inequality describes the number of movies Parv can buy.

9.99 + 3.99x ≤ 50

Where x is the number of movies.

Solve for x.

9.99 + 3.99x ≤ 50

Subtract 9.99 on both sides.

3.99x ≤ 50 - 9.99

3.99x ≤ 40.01

Divide both sides by 3.99

x ≤ 40.01/3.99

x ≤ 10

This means the number of movies Parv can buy is 10.

We can cross-check.

9.99 + 3.99 x 10 ≤ 50

9.99 + 39.9 ≤ 50

49.89 ≤ 50

Thus,

The number of movies Parv can buy is 10.

Answers

Answer:

Step-by-step explanation:

The question is incomplete, as the coordinates of the three vertices.

I will answer your question using the following illustration.

Assume that the square is ABCD are the given coordinates are:

[tex]A = (3,1)[/tex]

[tex]B = (-1,5)[/tex]

[tex]C = (-5,1)[/tex]

Required

Find D

Let the coordinates of D be:

[tex]D = (x,y)[/tex]

---------------------------------------------------------------------------------------------------------

Calculate the slope of each side.

AB, BC, CD and DA using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

AB:

[tex]A = (3,1)[/tex] -- [tex](x_1,y_1)[/tex]

[tex]B = (-1,5)[/tex] -- [tex](x_2,y_2)[/tex]

So:

[tex]m_1 = \frac{5 - 1}{-1 - 3} = \frac{4}{-4} = -1[/tex]

BC:

[tex]B = (-1,5)[/tex] -- [tex](x_1,y_1)[/tex]

[tex]C = (-5,1)[/tex] -- [tex](x_2,y_2)[/tex]

So:

[tex]m_2 = \frac{1-5}{-5--1} = \frac{-4}{-4} = 1[/tex]

CD:

[tex]C = (-5,1)[/tex] -- [tex](x_1,y_1)[/tex]

[tex]D = (x,y)[/tex] -- [tex](x_2,y_2)[/tex]

So:

[tex]m_3 = \frac{y - 1}{x --5} = \frac{y-1}{x+5}[/tex]

DA

[tex]D = (x,y)[/tex] -- [tex](x_1,y_1)[/tex]

[tex]A = (3,1)[/tex] -- [tex](x_2,y_2)[/tex]

[tex]m_4 = \frac{1-y}{3-x}[/tex]

AB and CD are parallel sides. So, they have the same slope

i.e.

[tex]m_1 = m_3[/tex]

[tex]\frac{y-1}{x+5} = -1[/tex]

Solve:

[tex]y-1 =-x-5[/tex]

Make y the subject

[tex]y =-x-5+1[/tex]

[tex]y =-x-4[/tex] ---- (1)

BC and DA are parallel sides. So, they have the same slope

i.e.

[tex]m_2 = m_4[/tex]

[tex]1 = \frac{1-y}{3-x}[/tex]

Solve:

[tex]1-y =3-x[/tex]

Make y the subject

[tex]y =1-3+x[/tex]

[tex]y =x-2[/tex] ---- (2)

So, we have:

[tex]y =-x-4[/tex] and [tex]y =x-2[/tex]

Equate both:

[tex]y=y[/tex]

[tex]-x-4=x-2[/tex]

Collect like terms

[tex]-x-x=4-2[/tex]

[tex]-2x=2[/tex]

Solve for x

[tex]x = -\frac{2}{2}[/tex]

[tex]x = -1[/tex]

Substitute [tex]x = -1[/tex] in [tex]y =x-2[/tex]

[tex]y = -1-2[/tex]

[tex]y = -3[/tex]

So, the missing coordinate is:

[tex]D = (-1,-3)[/tex]
