The number, based on the fact that one quarter of the difference between the number and 3, is - 1, is - 1
How to find the number?The number can be denoted as x in which case, the formula of the situation would be:
1 / 4 ( x - 3 ) = - 1
The number can then be solved for by looking for the value of x with the quarter constraint :
1 / 4 ( x - 3 ) = - 1
x - 3 = - 1 / ( 1 / 4)
x = -4 + 3
x = - 1
The number is therefore -1

Step-by-step explanation:
According to the graph, the radius of this circle is 4, and the diameter is 8.
The circumference of a circle equals diameter * π.
Therefore, the answer is 8π
Hi there! I saw someone already posted the answer the question, sorry I was so late in posting this. In case you need more of an explanation, I can help with that. :)
So as you may know, , the circumference of a circle has a formula of 2(pi)radius. The radius of this circle is 4, it's half the diameter. So that would be 2(pi)(4), and, multiplying the like terms first, is 8(pi). That's 25.1327412287. But you could just write that as 8pi. That's B there. :)

The missing value in the table is 8 gallons.
What is gallons and quarts?Gallons and quarts are two measurements for volume. A gallon is the larger of the two, and it is a unit of measurement that is used to measure liquids. One gallon is equal to four quarts. A quart is a smaller unit of measurement, and it is also used to measure liquids. One quart is equal to one-fourth of a gallon. Both gallons and quarts are commonly used to measure liquids, such as water, milk, and other beverages. They are also used to measure fuel for cars, such as gasoline and diesel. Gallons and quarts are also used in the kitchen when measuring ingredients or cooking liquids. For example, a recipe might call for two quarts of chicken broth. In addition to measuring liquids, gallons and quarts are sometimes used to measure dry goods such as rice, beans, and other grains. For example, a recipe might call for two quarts of white rice. Knowing how to convert between gallons and quarts is important when measuring liquids or dry goods. One gallon is equal to four quarts, so if a recipe calls for two gallons, it can be converted to eight quarts. Likewise, if a recipe calls for four quarts, it can be converted to one gallon.Solution:
1 gallon = 4 quarts
In the table shows 2 gallons is 8, that means 2 x 4 = 8
4 gallons is 16, which is 4 x 4 = 16.
Likewise, in fourth row, quarts is 32, we have to find gallons.

What is meant by translation?A translation in Euclidean geometry is a geometric transformation that shifts each point of a figure, shape, or space by the same amount in one direction. Another way to think of a translation is as the addition of a constant vector to each point or as a change in the coordinate system's origin.
A sort of transformation called a translation involves moving each point in a figure the same distance in the same direction.
Translation in geometry refers to shifting a shape into a different position without altering it in any manner. Shape translation is introduced to students in Year 5 by providing them shapes on squared paper, which must then be moved a specific number of squares up, down, left, or right.
1) {f(x) + a} is f(x) shifted up (a) units
2) {f(x) – a} is f(x) shifted down (a) units
3) {f(x + a)} is f(x) shifted left (a) units.
4) {f(x – a)} is f(x) shifted right (a) units.
Let the given function be f(x) = 4x
When exists shifted 7 units to the left, we should apply rule (3) where a = 7

PLEASE SHOW FULL WORK AND explain
THANKS FOR YOUR TIME :)
If it took the class 30 minutes to paint 1 square foot of the mural created about Martin Luther King by Mr. Elliot's class, it will take 7 hours and 43 minutes to complete the task, based on mathematical operations.
What are mathematical operations?Mathematical operations basically involve addition, subtraction, division, and multiplication.
The area of the mural is determined by the multiplication of length and width.
The time taken to complete the whole painting is derived by proportionately equating the time it takes to paint 1 ft² to the time it would take to paint 15.4375 ft².
The length of the mural created = 4.75 feet
The width = 3.25 feet
The area of the mural = 15.4375 ft² (4.75 x 3.25)
The time to pain 1 ft² = 30 minutes
The total time to paint the whole mural = 463.125 minutes (15.4375 x 30)

The area of the square field, given that the length is [tex]5x^3y^5[/tex], is found by squaring the length. The area then becomes [tex]25x^6y^10[/tex].
Explanation:The field is a square, so all the sides have the same length. Given that the length is [tex]5x^3y^5[/tex], the area of a square equals the length of one side squared. So to find the area of the square, you square the length [tex](5x^3y^5)[/tex] which is [tex](5x^3y^5)^2[/tex]
The formula to square a binomial [tex](a+b)^2[/tex] is a² + 2ab + b². To square [tex](5x^3y^5)^2[/tex], you may square each term separately. 5² = 25, (x³)² = [tex]x^6[/tex] and [tex](y^5)[/tex]² =[tex]y^{10[/tex].

B(x)=50 + 30500x^2 -183000x^3
Find the maximum blood pressure and the donate at which it occurs
The pressure will be maximum at x = 0.1 cc.
What are functions?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y.The set X is called the domain of the function and the set Y is called the codomain of the function.Functions whose domain are the non - negative integers, known as sequences, are often defined by recurrence relations.Given a function as [tex]${\displaystyle f\colon X\to Y}[/tex] its graph is, formally, the set -[tex]${\displaystyle G=\{(x,f(x))\mid x\in X\}.}[/tex]
Given is that with a dosage of {x} cubic centimeters (cc) of a certain drug, the resulting blood pressure {B} in millimeters of mercury (mm of Hg), is approximated by → B(x) = 50 + 30500x² -183000x³.
In algebra, a cubic equation in one variable is an equation of the form → [tex]$ax^3+bx^2+cx+d=0[/tex].
The given equation is -
B(x) = 50 + 30500x² -183000x³
For the maximum pressure, we can write -
dB/dx = 0
d/dx (50 + 30500x² - 183000x³) = 0
d/dx (50) + d/dx (30500x²) - d/dx (183000x³) = 0
0 + 61000x - 549000x² = 0
- 549000x² + 61000x = 0
Solving the equation, we get -
x = 0 and x = 0.1
{x} cannot be 0. So, we can write -
x = 0.1 cc
Therefore, the pressure will be maximum at x = 0.1 cc.

What is Speed and Distance ?Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route. In other words, velocity is a vector, whereas speed is a scalar number.
The size or extent of the displacement between two points is referred to as distance. Keep in mind that the distance between two points and the distance traveled between them are not the same. The length of the entire journey taken to go from one point to another is the distance traveled.
The overall distance the object covers in a given amount of time is its average speed. A scalar value represents the average speed. It has no direction and is indicated by the magnitude.
Total distance travelled = 15 + 45 m = 60 m
Total time of travel = 12 + 15 + 20 = 47 sec
Avewrage speed = Total distance / total time = 60/ 47 = 1.28 m/sec

So, the expression is 4, -1
"d. 1/36⁻⁵" is not equivalent to 4, -1, but it is a mathematical expression that could be evaluated to a number. The 1/36 is the reciprocal of 36, which is a very small decimal value. And when we subtract 5 from that it will be even smaller negative decimal value.
Exponents are a shorthand way of expressing repeated multiplication of the same number. For example, the number "3 to the power of 2" is written as "3²" and means 3 x 3, or 9. The number "2 to the power of 3" is written as "2³" and means 2 x 2 x 2, or 8. The number being multiplied is called the "base" and the exponent is the number of times the base is multiplied by itself. In the example above, 3 is the base and 2 is the exponent in "3²", and 2 is the base and 3 is the exponent in "2³". In general, aᵇ means a multiplied by itself b times.
