Twenty less than four times an mover is twenty one what is the number
Answer:
10.25
Step-by-step explanation:
Define the variable
Let x be the unknown number.
Therefore:
[tex]\begin{aligned}& \textsf{Four times a number}: \quad & 4x\\& \textsf{Twenty less than four times a number}: \quad & 4x-20\\& \textsf{Twenty less than four times a number is twenty one}: \quad & 4x-20=21\end{aligned}[/tex]
To find the number, solve the found equation for x:
[tex]\begin{aligned}\implies 4x-20&=21\\4x-20+20&=21+20\\4x&=41\\\dfrac{4x}{4}&=\dfrac{41}{4}\\x&=10.25\end{aligned}[/tex]
Therefore, the unknown number is 10.25.
As an improper fraction, this is ⁴¹/₄.
As a mixed number, this is 10 ¹/₄.
Answer:
x = 10.25
Step-by-step explanation:
Given that,
→ Twenty less than four times a number is twenty one.
The equation we form,
→ 4x - 20 = 21
Now the value of x will be,
→ 4x - 20 = 21
→ 4x = 21 + 20
→ x = 41/4
→ [ x = 10.25 ]
Hence, the number is 10.25.
Singer A and Singer B had the two top-grossing concert tours for a certain year, together generating $443 million in ticket sales. If Singer B took in $29 million less than Singer A, how much did each tour generate?
If Singer B took in $29 million less than Singer A, it means that Singer A generates $236 million and singer B generates $207 million in tickets sale.
How much does singer A takes in ticket sales?The fact that singer B generated $29 million less than singer A means that if singer A generates x million , singer would generate (x-29) million in tickets salessingers:
A's earnings=xsinger B's earnings=x-29total earnings=x+x-29total earnings=2x-29total earnings=443443=2x-29

On a number line, B is between a and c. AB = 1/3ac
We may infer from the number line that A and B are separated by 8 units (AB).
Let AB stand for the separation between points A and B, and let AC stand for the separation between points A and C. Let B stand for the separation between points B and C. Hence:
Point B being halfway between A and C, we can infer:
AB + BC Equals AC (Postulated segment addition)
As a result, since the distance between points A and B is equal to 1/3 of AC:
AC/3 = AB = 1/3(AC)
But as shown in the accompanying image:
AC equals 16 – (–8) to 24 units.
Therefore:
AB = 1/24 = 8 unit
A and B are separated by 8 units.

Ron Sample is the grand prize winner in a college tuition essay contest awarded through a local organization's scholarship fund. The winner receives $8,000 at the beginning of each year for the next 5 years. How much (in $) should be invested at 6% interest compounded annually to award the prize? (Round your answer to the nearest cent.)
$
Based on the amount the winner receives, the interest rate to be compounded annually, and the number of years, the amount that should be invested to award the price is $35,720.80.
How much should be invested?The amount that should be invested is the present value of the $8,000 for the next 5 years. This amount would be the present value of an annuity due because constant payments that come at the beginning of a period are annuity dues.
Present value of annuity due = Annuity due x (Present value interest factor of annuity due, 6%, 5 years)
Solving for the amount to be invested to award the price gives:

Sports Depot's is implementing a new strategy to increase sales of tennis balls. The basic idea is to sell tennis balls in large quantities to nonprofit groups, who resell the balls to raise money. For example, a service organization at a local college bought 2,000 tennis balls printed with the college logo. Sports Depot charged $.50 each for the tennis balls, plus a $500 one-time charge for the stamp to print the logo. The service group plans to resell the tennis balls for $2.50 each and contribute the profits to a shelter for the homeless. A. What is the service organization's average cost for the printed tennis balls it buys from Sports Depot?
The average cost price of 2000 printed tennis balls will be $1500.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that a local college's service organization purchased 2,000 tennis balls with the school's logo on them. Tennis balls cost $.50 each from Sports Depot, and a one-time stamp costing $500 was added on top of that.
Total cost = ( 2000 x 0.5 ) + 500
Total cost = 1000 + 500
Total cost = $1500
Therefore, the average cost price of 2000 printed tennis balls will be $1500.

The graph of g is a translation 2 units left and 3 units up, followed by a reflection
in the y-axis of the graph of f(x) = x² - 2x.
Graph of g is a translation where g(x) = (x+2)^2 - 2x – 1
f(x) = x^2 - 2x
g(x) = f(x+2) + 3
Translation is a movement of the graph either horizontally parallel to the x-axis or vertically parallel to the y-axis. A translation is a geometric transformation that moves every point of a figure, shape or space by the same distance in a given direction. A translation can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system. In a Euclidean space, any translation is an isometry.
Hence , g(x) = (x+2)^2 -2(x+2) + 3 = (x+2)^2 - 2x - 1. When we graph the equations, we can confirm that our answer is correct.

Step-by-step explanation:
You want to know the image of the point (-4, -6) after reflection in the x-axis and translation 3 left and 1 down.
Composition of transformationsThe composition ...
[tex]T_{-3,-1}\circ r_{\text{x-axis}}[/tex]
is interpreted to mean reflection in the x-axis occurs first, then translation by (-3, -1).
That is, a composition of transformations is evaluated right to left.
ReflectionReflection in the x-axis moves a point from below the x-axis to the same distance above the x-axis. That is, the sign of the y-coordinate changes:
(-4, -6) ⇒ (-4, 6) . . . reflection in the x-axis
TranslationThe translation vector is added to the coordinates of the point:
(-4, 6) +(-3, -1) = (-4-3, 6-1) = (-7, 5)
The image of the point is located at (-7, 5).

Solve for the following equation . x^6-9x^3+10=0
Answer:
x = ∛10x = -∛10/2 +(∛10√3)/2ix = -∛10/2 -(∛10√3)/2ix = -1x = 1/2 -(√3)/2ix = 1/2 +(√3)/2iStep-by-step explanation:
You want to solve the 6th-degree equation x^6 -9x^3 +10 = 0.
QuadraticThe equation is basically quadratic in x^3. Substituting z = x^3, we have ...
z^2 -9z +10 = 0
(z -10)(z +1) = 0 . . . . . factored form
z = 10, z = -1 . . . . . . . values of z that make the factors zero
CubicsNow, we have two cubic equations to solve:
x^3 = 10 ⇒ x = ∛10x^3 = -1 ⇒ x = ∛(-1) = -1The real root is given by the cube root function. The imaginary roots are that value multiplied by 1∠±120° = (-1/2 ±(√3)/2i). Then the six roots are ...
x = ∛10x = -∛10/2 +(∛10√3)/2ix = -∛10/2 -(∛10√3)/2ix = -1x = 1/2 -(√3)/2ix = 1/2 +(√3)/2i__

$850 at 7% compounded annually for 3 years how do you calculate earned interest?
Answer:
$191.29
Step-by-step explanation:
Use the formula
[tex]A = P(1 + \dfrac{r}{100})^n[/tex]
where P is amount deposited, A the accrued amount, n number of years and r the interest rate in % compounded annually
The division by 100 is necessary to convert r% to a decimal for calculations
We have P = 850, r = 7% and n = 3
Plugging these in we get
[tex]A = 850\cdot (1 + (\dfrac{7}{100})^3\\\\A= 850\cdot(1 + 0.07)^3\\A = 850\cdot1.07^3\\\A = \$1,041.29[/tex]

The correct statements regarding the linear function in the graph are:
The three points form a straight line.The graph does not pass through the origin.The graph does not a show a proportional relationship.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.From the points, we have that:
When x changes by 4, y changes by 6.When x changes by 6, y changes by 9.When x changes by 2, y changes by 3.Hence these points form a straight line with a slope of 1.5, that is:
y = 1.5x + b.
When x = 1, y = 3, hence we use it to find b as follows:
3 = 1.5 + b
b = 1.5.
Hence the relation is:
y = 1.5x + 1.5.
