A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. There are four possible math operations here: addition, subtraction, multiplication, and division.

Given: 40/8 + 3² + (15 - 7) × 2

The order of operations instructs you to begin by assessing parenthesized expressions. This is done by deducting 7 from 15.

40/8 + 3² + 8 × 2 . . . . (15 - 7) = 8

Then you evaluate exponential terms.

 40/8 + 9 + 8 × 2 . . . . . 3² = 9

Next, multiply and divide from left to right. In this case, division comes before multiplication.

 5 + 9 + 8 × 2 . . . . . divide 40/8 = 5

 5 + 9 +16 . . . . . . multiply 8 × 2 = 16

The order in which they performed be

14 + 16 . . . . add 5 + 9  

30 . . . . . . . add 14 + 16

The complete question is:

Using the order of operations, what are the steps for solving this expression?

By using the property of measure of an arc from the central angle

m(arc MQN) = 225°

m(arc MPN) = 135°

If m(arc KJH) = 312°

m∠1 = 48°

What is the measure of an arc from the central angle?

The measure of an arc from the central angle is the portion of the circumference of a circle that the arc spans. The measure of an arc is typically given in degrees.

In the given figure

by using the property of measure of an arc from the central angle

m(arc MQN) = 225°

m(arc MPN) = 360° - 225° = 135°

In the second figure,
If m(arc KJH) = 312°

m∠1 = 360° - 312° = 48°

Hence, by using the property of measure of an arc from the central angle

m(arc MQN) = 225°

m(arc MPN) = 135°

If m(arc KJH) = 312°

m∠1 = 48°

Step-by-step explanation:

To solve this problem, we can use the law of cosines. The law of cosines states that for any triangle with sides a, b, and c, and an angle C opposite side c,

c² = a² + b² - 2abcos(C)

In this problem, we can consider the man's starting point as the origin, and the distance he travels in the first leg as the first side of the triangle (a = 4km). The distance he travels in the second leg is the second side of the triangle (b). The angle between the two legs is the angle opposite side c, which is 90 degrees since the man changes direction from due west to southwest.

Therefore, we can use the law of cosines to find the distance he traveled in the second leg:

c² = a² + b² - 2abcos(90)

c² = 4² + b²

c = √(4² + b²)

c = √(16 + b²)

We know that the bearing of the second leg is 197 degrees, which is equivalent to a bearing of -163 degrees, since bearing measurements are taken clockwise from due north.

So we can use the law of cosines to find the distance he traveled in the second leg:

b = √(c² + a² - 2ac cos (-163))

We can now plug in the values we know:

b = √(c² + 4² - 24c*cos(-163))

We can now solve for c:

c = √(b² + 16 - 8bc)

The man is then southwest of his starting point, so the distance from his starting point to the final point is c.

well, it comes down to, if f(x) is indeed an inverse of g(x) and the other way around, then f(  g(x)  ) = x, and likewise g(  f(x)  ) = x, so let's check if f(  g(x)  =x

now, we could do a test by doing g(  f(x)  ), however we don't need to, since f(  g(x)  ) ≠ x, they're not inverse of each other.

The slope of the line represented by 4x-7y=62 is 4/7. A line's steepness is measured by its slope. The mathematical expression for slope is "rise over run."

Option A is correct.

In mathematics, a line's slope is the ratio of the change in the y coordinate to the change in the x coordinate. The net change in the y-coordinate and the net change in the x-coordinate, respectively, are denoted by the symbols delta y and delta x.

          We are given equation as 4x-7y=62

First, let's write it in the slope-intercept form .In general, slope-intercept form is                                    y=mx + b

where m is the slope

So, writing the equation in the form, we get

                                    ⇒-7y = 62-4x

                                        ⇒7y = 4x-62

                                          ⇒y = 4x/7-62/7

Now, matching the equation with the general form,

                                          m = 4/7

Hence, the slope of the line represented by 4x-7y=62 is 4/7.

$97.056 is the total interest accrued after the first month.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, You (or your parents) purchase a new car for $19,725.00 plus 4.75% sales tax. The down payment is $2,175.00 and you (or your parents) have an average credit rating.

The cost of car = 19,725*(1.0475) = 20,661.9375

Down payment = 2,175

So balance amount, P= 20661.9375-2175 = 18,486.9375

So interest for the average rating of a new car = 6.30%

So the interest accrued in first month = 18,486.9375*0.063/12 = $ 97.056

An open circle is at 5 and a bold line starts at 5 and is pointing to the right. Therefore, option B is the correct answer.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is -3(2x - 5) < 5(2 - x).

Here, -6x+15<10-5x

Add 5x on both the sides of an inequality, we get

-x+15<10

Subtract 15 on both the sides of an inequality, we get

-x<10-15

-x<-5

Multiply -1 on both the sides of an inequality, we get

x>5

The Mewtwo card is twice as old as the Snorlax card, so the Mewtwo card is two years old. The Raichu card is five times as old as the Snorlax card, so it must be ten years old.

Since the Raichu card is two years older than the Mewtwo card, it must be eight years old. Therefore, the Raichu card was made eight years ago.

We can use the z-score formula to find the probability of cans having a volume less than 355 ml.

z-score = (355 - 358.2) / 1.8 = -1.78

Probability of cans having a volume less than 355ml = P(z < -1.78) = 0.0372

The mother must drive at a speed of 6 mph to reach Anna in ten minutes.

To find the speed required for the mother to reach Anna in ten minutes, you need to calculate the distance between them and the time it takes to close the gap.

Let x be the speed of the mother's car in mph.

In one hour, Anna will have covered 6 miles.

In ten minutes, the mother will have covered x * 10/60 miles.

The total distance between them is 6 + x * 10/60 miles.

The mother must cover this distance in ten minutes, so:

x * 10/60 = 6 / (10/60)

x = 6 * (10/60) / (10/60)

The term integers in math is defined as are the collection of whole numbers and negative numbers.

Here we know that x and y are the integers,

Then it takes both positive and negative numbers.

Then we take y=1, then we apply it on the expression then we get,

=> 3x(1) = 3x.

Similarly here we have take that xy|z means xy is a factor of z,

Here we can say xym = z for some integer m.

=> x × ym = z, and ym is an integer by closure hence x is a factor of z such that x|z.

Similarly here we can also y * xm = z, and consider xm is an integer, hence y is a factor of z, i.e. y|z.

Where in the third one, we can take x|y means there exists a constant is written as y = kx

Where as y|x means there exists a constant written as x = cy

When we compare these, then we get,

=> y = kx = kcy

Here we have to true if kc = 1 and since k and c are integers, then we have k = c = 1

what are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.
