Based on the right triangle altitude theorem, the term that completes the equation is: a. YZ.

The right triangle altitude theorem state that when an altitude is drawn to from the vertex of a right triangle to intersect the opposite side perpendicularly, the length of the altitude would be equal to the geometric mean of the line segments that are formed by the altitude on the right triangle's hypotenuse.

In other words, the square of the length of the altitude equals the product of the line segments formed, according to the right triangle altitude theorem.

XZ = altitude

WY = hypotenuse

WZ and YZ are the line segments formed.

Therefore, the equation would be:

XZ² = (WZ)(YZ) [right triangle altitude theorem]

Derek can watch a maximum of (M/7.25) number of movies, where $M represents his budget for movie.

In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. There are two types of inequalities namely strict and slack inequalities.

Given is Derek who enjoys going to the movies. He budgets a month for movies and admissions for one movie cost $7.25.

Assume that the budget for movies is $M.

The cost of admission in one movie = $7.25

Suppose that Derek can watch [x] number of movies. Then, the given inequality will represent the number of movies Derek can watch -

7.25x ≤ M

x ≤ (M/7.25)

Therefore, Derek can watch a maximum of (M/7.25) number of movies, where $M represents his budget for movie.

Step-by-step explanation:

The question is,

→ what is 1656 divided by 16?

Forming as problem,

Let's solve the problem,

→ 1656 ÷ 16

→ 103.5

Thus, the answer is 103.5.

Using the normal distribution, the 98th percentile of the distribution of scores is of 2084.

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is given by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean of the scores is given as follows:

[tex]\mu = 1468´[/tex]

The 20th percentile is of 1216, meaning that when X = 1216, Z = -0.84, hence the standard deviation is calculated as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-0.84 = \frac{1216 - 1468}{\sigma}[/tex]

[tex]0.84\sigma = 252[/tex]

[tex]\sigma = \frac{252}{0.84}[/tex]

[tex]\sigma = 300[/tex]

The 98th percentile is X when Z = 2.054, hence it is calculated as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

2.054 = (X - 1468)/300

X - 1468 = 300 x 2.054

X = 2084.

By using Permutation, the total number of ways in which we can choose a starting lineup consisting of a quarterback, a running back, an offensive lineman, and a wide receiver is 1512.

Permutation is defined as the arrangement of items in a specific or a particular order.

Since there are 3 choices for the position of offensive lineman, and for the next position there are 9 choices, similarly 8 choices for the next position  and 7 choices remain for the last position.

So we get, 3x9x8x7 =1512,  by the concept of Permutation.

The largest positive integer m that divides both x and y is the GCF of two or more non-zero integers, x, and y. The GCF stands for the greatest common factor. Here, greatest might be changed to highest, and factor to divisor. Therefore, the greatest common factor is often referred to as the highest common divisor )(HCD), highest common factor (HCF), or greatest common divisor (GCD.

Fractions, which are frequently employed in daily life, are almost always utilized with GCF. Finding the GCF of the denominator and numerator will allow you to obtain the necessary reduced form for simplifying a fraction or ratio. The greatest number that can divide two numbers x and y is their GCF.

First let's find the length of AC using the Pythagorean theorem in the right triangle with legs of 5 and 12:

So the diagonal of the rectangle is 13 units. Now, since the area of a triangle is calculated as the product of a base and the corresponding height, we can use the legs as base and height or we can use the segment AC and the corresponding height, and the result is the same, so we have:

So the distance from B or D to the diagonal AC is 60/13 units.

c=10

Hello!

The solution to the problem 2c - 5 = 15 is

c = 10

Step-by-step explanation:

The first step is to add 5 to both sides of the equation.

2c - 5 = 15

2c - 5 + 5 = 15 + 5

The second step is to simplify by adding the numbers.

2c - 5 + 5 = 15 + 5

2c = 20

The third step is to divide both sides of the equation by the same factor.

2c = 20

2c ÷ 2 = 20 ÷ 2

The fourth step is to simply by canceling out the numbers which are present in both the denominator and numerator, then divide.

2c ÷ 2 = 20 ÷ 2

c = 10

The value of f(x)/g(x)=x-2 for f(x)=x²-x³ + x² and g(x) = -x² and where x # 0 and the definition of function defines "function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)".

A function is a type of rule that produces one output for a single input. This is illustrated by the equation y=x². Any input for x results in a single output for y. Considering that x is the input value, we would say that y is a function of x. The property that every input is related to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs. A mapping from A to B will only be a function if every element in set A has one end and only one image in set B. Let A & B be any two non-empty sets.

Here,

f(x)=2x²-x³

g(x)=-x²

f(x)/g(x)=(2x²-x³)/-x²

=x²(2-x)/-x²

f(x)/g(x)=x-2

The definition of function defines "function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable)". The value of f(x)/g(x)=x-2 for f(x)=x²-x³ + x² and g(x) = -x² and where x # 0.

ANSWER

EXPLANATION

Nick has 4 quarts of ice and he wants to split it with 9 members of the team.

To solve this, we have to convert quarts to cups. We have that:

1 quart = 2 pints

and

1 pint = 2 cups

This means that:

1 quart = 2 * 2 cups

1 quart = 4 cups

So, 4 quarts will be:

4 quarts = 4 * 4 cups

4 quarts = 16 cups

Therefore, dividing the ice cream among 9 people would mean that we have to divide 16 cups by 9 people.

That is:

The complete statement is:

1 quart equals 2 pints, which equals 4 cups, so 4 quarts equals 16 cups. Dividing the ice cream among 9 people means each gets 1 7/9 cup(s)​

The relationship between the number of T-shirts and cost is defined by y = 2t + 3, where:

y is the total cost,

x is the number of t-shirts,

the 2 is the cost for 1 t-shirt ($/t-shirt), and

3 is a one=time charge of $3 for each order.

The graph (attached) shows a straight line with a y-intercept of 3, the initial order fee.  It is linear since the cost of a t-shirt remains the same egardless of order size.

w=L+15

p=(L+w)

150cm=L+L+15

Line c is also perpendicular to line a.

Suppose that c and b are perpendicular. This implies that:

Answer:

A = 540 m²

Step-by-step explanation:

consider the shape split into 3 rectangles

the length is divided into 3 congruent sections

single dash = 30 m ÷ 3 = 10 m

the width is divided into 3 congruent sections

double dash = 27 m ÷ 3 = 9 m

then area (A) is the total of the 3 rectangular areas

A of left rectangle = 10 × 9 = 90 m²

A of middle rectangle = 10 × (9 + 9) = 10 × 18 = 180 m²

A of right rectangle = 10 × 27 = 270 m²

total area = 90 + 180 + 270 = 540 m²

x = 5

Given the equation shown:

To get the value of "x", we will divide both sides by -6 to have:
