Step-by-step explanation:

since there is a 5 in the thousandths, we round the 1 in the hundredths up and get 17.32

1) You can find the number of possible methods through a tree diagram or the fundamental counting principles.

2) The total number of combinations is 360

To find the total number of combinations,

A Tree Diagram is a the various possibilities in a pictorial way. The diagram begins with a single point, which represents the initial decision, then branches out to indicate all possible outcomes for each successive option.

The Fundamental Counting Principle tells us that if there are 'n' ways doing a thing and 'm' ways to do another, there are n x m ways to do both. Which means that the total number of outcomes equals the product of the number of ways each job can completd.

Answer:

Step-by-step explanation:

They will meet after 4 minutes from 3:00 p.m. So, they will meet at 3:04 p.m.

Let's find the time it takes for Tommy and his Dad to meet.

Let t be the time (in seconds) from 3:00 p.m. when they meet.

Tommy's distance covered (T) after t seconds is given by:

T = Tommy's speed * t

   = 1.35 m/s * t

His Dad's distance covered (D) after t seconds is given by:

D = Dad's speed * t

  = 1.65 m/s * t

Since they meet when the sum of their distances is equal to the total distance between home and school, we can write the equation:

T + D = 720 meters

Substitute the expressions for T and D:

1.35t + 1.65t = 720

t = 240 seconds

Since 1 minute is equal to 60 seconds, let's convert the time to minutes:

t = 240 seconds / 60 seconds/minute

t = 4 minutes

They will meet after 4 minutes from 3:00 p.m. So, they will meet at 3:00 p.m. + 4 minutes = 3:04 p.m.

Things to note :

Subtracting a negative value will be equals to adding.

To add/subtract 2 fractions together, the denominator must be the same.

The slope-intercept form is y=mx+b

m=slope=-5

y-int/b = 300

so, y = -5x+300 is the equation of the line

The linear inequality depicted by the graph is: [tex]y \leq \frac{2}{3}x + \frac{1}{5}[/tex]

A linear function is modeled by:

y = mx + b

In which:

For this line, when x = 0, y = 0.2, hence the y-intercept is of b = 0.2. When x = 3, y = 2.2, hence the slope is given as follows:

[tex]m = \frac{2.2 - 0.2}{3 - 0} = \frac{2}{3}[/tex]

Hence the equation of the line is:

[tex]y = \frac{2}{3}x + 0.2[/tex]

[tex]y = \frac{2}{3}x + \frac{1}{5}[/tex]

The inequality is the values below(less) than the line, also including it, as it is not dashed, hence:

We will spend altogether $1400.

We know that the process of combining two or more items is known as an addition. Addends are the sums of the numbers that are added. The addition sign (+), which is positioned in between the addends, is present. The outcome of adding the addends is referred to as the sum.

Given that

Food = $594.09

Clothes = $204.33

Trips = $100.40

Transport = $310.05

Answer:

6 projects

Step-by-step explanation:

Original ribbon length = 24 yards

After 10 yards given to sister, Mia is left with 24-10 = 14 yards of ribbon

Each project requires 2 1/4 yards of ribbon.

2 1/4 is 9/4 yards as an improper fraction (2 * 4 + 1 is the numerator and the denominator is unchanged)

We now have to figure out how many times 9/4 yards goes into 14 yards.

For this,

14 ÷ 9/4.
To do this, flip the numerator and denominator of the fraction and multiply

14 ÷ 9/4 = 14 × 4/9 = 56/9 . We ignore any remainder.

9 goes into 56 6 times with remainder of 2 (ignore remainder)
In other words the greatest number of projects = 6

The two triangles are similar by the AA Similarity theorem.

The height of the tree can be calculated by figuring out the ratio between the distance between the mirror to her feet and the distance from the mirror to the tree

From Law of Reflection, we know that the angle of incidence and the angle of reflection are equal to each other.

Now, triangles can be proved similar by the AA, SAS, or SSS theorems. However, in this question, the triangles as seen in the attached image can be proved similar by the AA similarity theorem.

This is because both triangles have one congruent angle in common.

Sarah and the tree are standing straight and perpendicular to the ground and as such, the angles formed by Sarah and the tree are right angles.

The above tells us that the two triangles have two angles in common, making them similar triangles by the AA (Angle Angle) similarity theorem.

Since the triangles are similar, it means that the ratios of the sides of the triangles will be the same. Thus,  if Sarah knows the distance from the mirror to her feet and the distance from the mirror to the tree, she can create the ratio between the two triangles.

The whale exists swimming at 30 mph in calm water and the current exists flowing at 10 mph.

Let x be the speed of a whale in calm water

and y be the speed of the current

In 7 hours the whale swims against the current and travels 140 miles:

7(x - y) = 140

x - y = 140/7

x - y = 20 ...........(1)

In 3.5 hours the whale swims the same distance with the current:

3.5(x + y) = 140

x + y = 140/3.5

x + y = 40 ...........(2)

Adding (1) and (2), we get the value of x:

x - y = 20  + ...........(1)

x + y = 40 ...........(2)

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

2x = 60

x = 60/2

x = 30

Using this value for "x" in either (1) or (2) we can solve for "y":

x - y = 20 ...........(1)

substitute for "x"

30 - y = 20

10 = y

The probability that a randomly selected PC costs more than 1200 will be 0.006. The least expensive 10% of personal computers cost less than what amount will be 820.8.

The Gaussian distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.

The z-score is given as

z = (x – μ) / σ

Where μ is the mean, σ is the standard deviation, and x is the sample.

The average price of a personal computer (PC) is $949.

If the computer prices are approximately normally distributed and standard deviation is $100.

Then the probability that a randomly selected PC costs more than 1200 will be

z = (1200 – 949) / 100

z = 2.51

Then  the probability will be

P(x > 1200) = P(z > 1200)

P(x > 1200) = 1 – P(z < 1200)

P(x > 1200) = 1 – 0.99396

P(x > 1200) = 0.0060366

The least expensive 10% of personal computers cost less than what amount will be

z-value for 10% will be -1.282.

– 1.282 = (x – 949) / 100
