calculate -8000 * 41 with long division​

Answer:

3 and 4 or {3,4}

Step-by-step explanation:

3 and 4 are the only numbers greater than 2, but less than 5.

The value of x = 25 % (option b) in 79% of 8400 + 66.66% of 4800 = 120% of 7200+ x% of 4784. by converting the percentages.

79% of 8400 = ( 79/100) x 8400

                     = 6636

66.66% of 4800 = (66.66/100)x4800

                      = 3199.68

120% of 7200 = (120/100)x7200

                       = 8640

x% of 4784  = (x/100) x 4784

we are given that, 79% of 8400 + 66.66% of 4800 = 120% of 7200+ x% of 4784. what is the value of x :

therefore, 6636 + 3199.68 = 8646 + (x/100) x 4784

                 (x/100) x 4784 = 6636 + 3199.68 - 8646

                                         = 1189.68

                                (x/100) = 1189.68/4784

                                            = 0.248

                                    x = 0.248 x 100

therefore , the value of x is equals to 24.8 % or 0.248 which is approximated to 25 % that is option (b)

The fraction of exponents  3⁻¹ divided by 3⁴ equals = 243.

An element of a whole or, more broadly, any number of equal pieces, is represented by a fraction. When used in conversational English, a fraction indicates the number of components of a particular size, as in one-half, eight-fifths, and three-quarters. There are three main fraction kinds in mathematics.

They come in three varieties: proper fractions, incorrect fractions, and mixed fractions. Numerator and denominator terms are known as fractions. We define its types in light of these two words. There are seven different types of fractions: equivalent fractions, like fractions, mixed fractions, appropriate fractions, and fractions with the same numerator.

If A Ferris wheel is 45 meters in diameter and boarded from a platform that is 1 meters above the ground. The number of minutes  of the ride that are spent higher than 35 meters above the ground is: 2minutes.

Ferris wheel radius = 45/2

Ferris wheel radius = 22.5 meters

When the Ferris wheel is at the 12 o'clock position, the center of the wheel is at a height of 22.5 + 1 = 23.5 meters above the ground.

When the Ferris wheel is at the 3 o'clock position, the highest point on the wheel is at a height of (22.5 + 1) + (22.5) = 46 meters above the ground.

So the time spent higher than 35 meters is the time spent between 3 o'clock and 12 o'clock positions, which is a quarter of the full revolution time is:

Time spent higher than 35 meters = 8/4

Time spent higher than 35 meters = 2 minutes

What is an equation in function notation?

An equation involving x and y, which is also a function, can be written in the form y = “some expression involving x”; that is, y = f ( x). This last expression is read as “ y equals f of x” and means that y is a function of x.

a. Let y be Ainsley's salary after x years of working at the bookstore.

The equation representing Ainsley's salary as a function of the number of years she has been working at the bookstore is y = $24,500 * (1 + 0.03x).

b. To find Ainsley's salary when she begins her fourth year working at the bookstore, we need to plug in x = 3 into the equation:

y = $24,500 * (1 + 0.03x)

y = $24,500 * (1 + 0.03 * 3)

y = $24,500 * 1.09

y = $26,940.

In this acronym, O is the opposite side, A is the adjacent side, and H is the hypotenuse. S is for the SIN function. C is for the COS function. T is for the TAN function.

We can calculate the length of the string by using the COS function.

So we can say the tangent of angle [tex]\beta[/tex] is the opposite side divided by the adjacent side.

[tex]tan( \beta)=\frac{O}{A}[/tex]

We are given the angle and the opposite side. We are looking for the adjacent side.

Lets solve for [tex]A[/tex].

Take the reciprocal of both sides.

[tex]\frac{1}{tan(\beta)} =\frac{A}{O}[/tex]

Multiply both sides by [tex]O[/tex].

[tex]\frac{1}{tan(\beta)} *O=A[/tex]

The probability of a flight will not arrive on time is 231/1000

Probability is the function that measures the chances that an outcome of a random event will be as expected. In this way you can measure how likely it is that an event will happen.

Probability requested is equivalent to:

Flights arrive on time= 769

Total flights = 1000

P(arrive on time) = Flights arrive on time / Total flights

P(arrive on time) = 769/1000

P (not arrive on time) = 1 - 769/1000

P (not arrive on time) = (1000 - 769)/1000

The total atomic masses of a compound's constituent atoms, expressed in grams per mole, make up the compound's molar mass.

You must adhere to the grams to moles formula in order to accurately calculate the number of moles, n, of a substance with a given mass, m, (in grams): The molar mass of this substance is M, and n = m / M.

The atomic mass of an element is multiplied by the number of its atoms. Add the values once you've completed this for all the atoms to determine the amount of grams in a mole.

A compound's molar mass is determined by adding the atomic masses of all of its constituent atoms together in grams per mole. The number of moles in a compound cannot be measured physically, but we may connect its mass to the number of moles by utilizing the molar mass of the compound as a direct conversion factor.

A unit rate is defined as the rate for one of something. For example, if 10 oranges cost $50, the unit rate will be $50/10 = $5 i.e.  $5 for one orange.

PART 1

In order to determine which store offers the better buy for bottled water, we need to calculated the unit rate for each store. That is:

Unit rate = price / number of items

In Value Market, $2.99 for 24 bottles:

Unit rate  = $2.99/24 = $0.12

Sammy's Bulk Store, $3.96 for 36 bottles:

Unit rate  = $3.96/36 = $0.11

Thus, Sammy's Bulk Store offers better buy

PART 2

For  Hot dogs:

In Value Market, $3.19 for a pack of 8:

Unit rate  = $3.19/8 = $0.4

C = 0.4n

Sammy's Bulk Store, $54.40 for a pack at 12:

Unit rate = $4.49/12 = $0.37

C = 0.37n

Distance is the broad, directionless movement of a moving object. Distance can be characterized as the amount of territory an object has covered, regardless of something like the originating or ending location. Distance is defined as the extent or size of the difference between two places. The space between two positions and the distance traveled between them are not the same thing, it should be emphasized. The distance traveled is the entire length of a path that connects two places. Distance is the actual travel distance of a body. It is also known as path length. For instance, OP = 360 m would be the length of the path for an object traveling from point O to point P.

If you replace the w with 6 you get 53.

The terms empty set, null set, and void set are all used to describe a set that is empty of any elements.

The empty set is the only set in mathematics that possesses no items; its size or cardinality is 0. While in other theories, its existence can be inferred, some axiomatic set theories guarantee the presence of the empty set by introducing an axiom of empty set.

An empty set is a set that contains no elements and can be represented by the symbol, which indicates that it is empty of elements. It has a definite number of elements since the finite set contains a countable number of items and the empty set has none. An empty set is a finite set since it has a cardinality of zero.

Next, we take the logarithm base (5/6) of both sides:

n = log base (5/6) of (1 x 10^-5)

Using logarithm rules, we can simplify this to:

n = log base (5/6) of 1 - log base (5/6) of 10^-5

Using logarithm tables or a calculator, we find that:

log base (5/6) of 1 = 0

log base (5/6) of 10^-5 = -12.175074
