Answers

Answer:

  angle 5

Step-by-step explanation:

Given transversal x crossing lines y and z and angles numbered 1 to 8, you want the number of the angle that is an alternate interior angle to angle 4.

Alternate interior angles

In this context, "alternate" mean the angles are on opposite sides of the transversal. "Interior" means the angles are between the lines the transversal crosses.

The term "alternate interior angles" is used to refer to angles that have their vertices at the intersection points where the two lines cross the transversal. (It excludes angles that have the same vertex, or do not share a side.)

The angle that is an alternate interior angle relative to angle 4 is angle 5.

$72 is 4.5% of what amount

Answers

$72 is 4.5% of 6.25 amount. 6.25 Percentage of  72 is 4.5.

By considering the given information

[tex]72\times x=4.5\\x=\frac{4.5}{72}\times 100\\ x=6.25[/tex]

A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. percent, which is a relative value used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

Solution :

The percentage is a rate or proportion per hundred,

The percentage is also used more generally to mean any proportion, as in Studies have shown that a large percentage of people love cute animals.

A percent is one one-hundredth (1/100) of something. The percentage refers to the rate or proportion of that one hundred. Usually, you will see the word percentage used in math equations or statistics or when someone is measuring the increase and decrease in rates

$72 is 4.5% =?

$72  is 10% = $7.2

$72 is 5% = $7.2 /2 = $3.6

$72 is 1/2%= $72 * .5/100 = $.72*.5 = $ 0.36

$72 is 4.5% = 5% - .5% = $3.6- $.36 = $3.24

The inverse is the false and the Converse is the true.

According to the statement

So, For this purpose, we know that the

A conditional statement may be a statement which will be written within the form “If P then Q,” where P and Q are sentences. For this conditional statement, P is named the hypothesis and Q is termed the conclusion.

From the given information:

if 3 could be a prime quantity then 5 is a fair number.

Then

a) Inverse: If 3 isn't a primary number, then 5 isn't a fair number. (True)

Contra positive: If five isn't an excellent number, then 3 isn't a main number. (False)

Converse: If 5 is a good number, then 3 may be a prime quantity. (True).

Solving for the variable gives f = 100 - 2h/5

What is subject of formula?

Subject of formula can be defined as the variable that is expressed in terms of other variables in a given expression, function of equation.

It is the variable worked out in an equation and left to stand on its own on one side of the equality sign

Given the equation;

5f+2h = 100

To make 'f' the subject of formula, we take the following steps;

Take '2' over the equality sign

5f = 100 - 2h

Now, let's make 'f' the subject by dividing both sides by its coefficient which is 5

We have;

5f/5 = 100 - 2h/5

Divide through

f = 100 - 2h/5

Thus, solving for the variable gives f = 100 - 2h/5

describe and illustrate the situation when the minimum of a two variable function can be placed higher than its maximum. what type of extrema is this?

Answers

For the rare case that the outcome of the second derivative matrix examination is inconclusive, higher order derivatives have to be examined.

What do math extrema mean?

Any point in calculus when the value of a function is either the highest (a maximum) or the lowest (a minimum) (a minimum). There are maxima and minima that are both absolute and relative (or local).

Identify every stationary point. The solution set that results from setting the partial first derivatives to zero includes those points.Look at each stationary point's personality. This is done explicitly in the first case by looking at the eigenvalues of the second derivative matrix. The fact that there are quick formulas for this if there are just two variables, is superior.Higher order derivatives must be investigated in the improbable event that the results of the second derivative matrix study are ambiguous. Sadly, no set recipes can be developed in this situation; rather, each function must be considered individually.

Answer:1.75

Step-by-step explanation:

7x+8=3x+15

4x+8=15

4x=7

x=1.75

Answer is 20.25 angle 1

Step by step

Angle 1 and angle 3 are vertical angles, they are congruent /the same/ equal.

Angle 1 = 7x + 8
Angle 3 = 3x + 15



So our equation is

7x + 8 = 3x + 15

Solve for x

Subtract 3x from both sides to combine variables

7x - 3x + 8 = 3x - 3x + 15

4x + 8 = 15

Now subtract 8 from both sides to isolate x

4x + 8 - 8 = 15 - 8

4x = 7

Divide both sides by 4 to solve for x

4/4 x = 7/4

x = 1.75

Now to answer the question

What is the value of angle 1?

Angle 1 is 7x + 8

Substitute 1.75 for x in the equation

(7)(1.75) + 8 = angle 1

20.25 = angle 1

Check your work and do the same for Angle 3

3x + 15

Substitute 1.75 for x

(3)(1.75) + 15 = angle 3

20.25 for angle 3
