Answer:

  x = 6

Step-by-step explanation:

The angle bisector divides the triangle proportionally. Here, the top segment on each half is double the length of the bottom one, (8 = 2·4), so ...

  x = 2·3

  x = 6

_____

If you like, you can write that as a proportion:

  x/3 = 8/4

  x = 3(8/4) = 3·2 . . . . . multiply by 3 to get x by itself

  x = 6

Answer:

C) A = \(3w^{2} - 4w\)

Step-by-step explanation:

First, read through what the question is asking.

Now, read it again, but slowly and take in everything it is saying (Don't read into it too slowly, or else you will over-complicate the problem and get frustrated - told from experience :) )

Alright, 4 less than 3 times the width. So, lets rearrange this and give width a variable (w).

So, the length is equal to:

l = 3w - 4

and the width is equal to:

w = w

The area of a rectangle is A = l * w

Let's plug in the values.

A = (3w - 4) * w

Now, simplify:

A = \(3w^{2} - 4w\)

A = \(3w^{2} - 4w\) is your final answer.

the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.

We are given that the selling price of a pick up item is given as:

Selling price = $ 18,760

Now, it is also given that, on every sale, the salesperson gain a commission of 4.5 % as their pay.

The money they get paid for one pick up that they sell will be calculated by finding the percentage. So, we get that:

Money = 4.5 % of $ 18,760

Money = 4.5 / 100 × $ 18,760

Money = 0.045 × $ 18,760

Money =  $ 844.2

Therefore, we get that, the salesperson will be paid $ 844.2 for the one pickup they sell for $ 18,760 as 4.5 % commission is theirs.

In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be modeled or represented by the following mathematical equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) by using various data points as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = (20 - 15)/(10 - 5) = (5 - 4)/(1 - 0)

Constant of proportionality, k = 1.

1. Bank 1 is the best option for opening a savings account for one year, as it offers the highest total amount after one year.

2. Bank 1 is the best option for opening a savings account for one year, as it offers the highest total amount after one year.

We will use the formula A = P(1 + r/n)^(nt).

Bank 1:

= 3675(1 + 0.0236/4)^(4*1)

= 3762.50058402

= $3762.50

Bank 2:

= 3675(1 + 0.0236/1)^(1*1)

= 3696.6825

= $3696.68

Bank 3:

= 3675(1 + 0.0236/2)^(2*1)

= 3718.49292675

= $3718.49

To calculate which bank is the best option to open a savings account for twelve years, we can use the same formula and plug in t = 12:

Bank 1:

= 3675(1 + 0.0236/4)^(4*12)

= 4874.02928821

= $4874.03

Bank 2:

Answer:

0.1791 acres (rounded to 4 decimal places)

Step-by-step explanation:

67 pounds seeds 12 acre, the ratio can be written as:

Pounds : Acres = 67 : 12

Since, we want Acres PER POUND of seed, we need to divide Total Acres (12) by Total Pounds (67).

Note: per "quantity", we always divide by that "quantity".

So, we have:

So, 1 pound of seed cover 0.1791 acres of land (rounded to 4 decimal places for accuracy)

We can expand

\(f(x,y,z) = xy\ln(yz) = xy \ln(y) + xy\ln(z)\)

Then using the product and chain rules,

\(\dfrac{\partial f}{\partial x} = y\ln(y) + y\ln(z) + \boxed{y\ln(yz)}\)

\(\dfrac{\partial f}{\partial y} = x\ln(y) + \dfrac{xy}y + x\ln(z) = \boxed{x\ln(yz) + x}\)

\(\dfrac{\partial f}{\partial z} = \boxed{\dfrac{xy}z}\)

Step-by-step explanation:

A basketball game does not end in a tie. This means that it is either the team wins the game or they draw the game. These outcomes are independent becuase winning one game has no effect on the outcome of the next game. This means that we have a binomial distribution here. the formula for binomial distribution is expressed as

P(x) = nCx * p^x * q^(n - x)

where

n is the number of trials

x is the number of successess

p is the probability of success

q is the probability of failure

We are concerned with the outcome of winning. This means that success is when the team wins. Thus,

p = 4/7

q = 1 - p = 1 - 4/7 = 3/7

n = 15

x = 8

We want to find P(x = 8)

By applying the binomial distribution formula,

P(x = 8) = 15C8 * (4/7)^8 * (3/7)^(15 - 8)

P(x = 8) = 6435 * (4/7)^8 * (3/7)^7

P(x = 8) = 0.194

The probability that in a season of 15 games they will win exactly 8 games is

0.194

We know that

• Mt. Everest height was 8,850 meters in 1999. This is the initial condition.

• The rate is 5cm per year or 0.05 m per year.

Based on the given information, we express the following equation.

Where x is years and y is height in meters,

Now, in year 0, x = 0.

ax + by = 6000 and a + 5 = b are two equations that might be used to calculate how many soup cans and frozen dinners were purchased.

There are several methods to define a formula. A mathematical statement that establishes the equivalence of two mathematical expressions is the definition of an equation in algebra.

This is best shown by the formula 3x + 5 = 14. In this instance, the word equal comes between the phrases 3x + 5 and 14. Even the most basic algebraic equations include the usage of mathematical variables.

Let frozen supper be y and soup cans be x.

X now has 300 mg of sodium in it.

x = 300

Y also has 450 mg of sodium in it.

y = 450

Samuel reportedly buys five more frozen dinners than soup cans, and they all have a combined salt content of 6000 mg.

Let the number of frozen dinners be "b," and the number of soup cans be "a."

ax + by = 6000

⇒ a(300) + b(450) = 6000 ...1

Samuel bought 5 more frozen dinners than soup cans, according to the inquiry, which results in equation

a + 5 = b ...2

Now, by changing the value of b in equation 1 we obtain,

⇒ a(300) + (a + 5)(450) = 6000

⇒ 300a + 450a = 6000 - 2250

⇒ 750a = 3750

⇒ a = 3750/750

⇒ a = 5

By changing the value of an in equation 2, we obtain

⇒ 5 + 5 = b

⇒ b = 10

So, ax + by = 6000 and a + 5 = b are two equations that might be used to calculate how many soup cans and frozen dinners were purchased, respectively, where x and y stand for soup cans and frozen dinners, respectively, and a and b stand for the quantity of soup cans and frozen dinners.

The graph for the given equation of a line with the coordinates (0, 6), (1, 2), (2, -2), (3, -6) and so on are plotted.

The equation of a line is 4x+y=6.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

Here, y=6-4x

Substitute x=0, 1, 2, 3, 4, 5,..... in the given equation, we get

When x=0

y=6

When x=1

y=2

When x=2

y=-2

When x=3

y=-6

So, the coordinates are (0, 6), (1, 2), (2, -2), (3, -6) and so on.

Therefore, the graph for the given equation of a line with the coordinates (0, 6), (1, 2), (2, -2), (3, -6) and so on are plotted.
