Pablo’s goal is to walk a total of 10 3/4 miles each week. He walked 2 1/4 miles on Sunday, 1 3/8 miles on Monday, and 1 7/8 miles on Tuesday. What equations can he use to find the number of miles he needs to walk the rest of the week to reach his goal? Choose two equations
If Pablo’s goal is to walk a total of 10(3/4) miles each week. He walked 2(1/4) miles on Sunday, 1(3/8) miles on Monday, and 1(7/8) miles on Tuesday , then the equation to find the number of miles he needs to walk is "15/8 + 11/8 + 9/4 + x = 43/4" .
the goal of Pablo to walk in a week is = 10(3/4) = 43/4 ;
the distance he walked on Sunday is = 2(1/4) = 9/4 ;
the distance he walked on Monday is = 1(3/8) = 11/8 ;
the distance he walked on Tuesday is = 1(7/8) = 15/8 ;
let the remaining distance be = x miles ;
So , this situation can be represented in equations as :
⇒ 15/8 + 11/8 + 9/4 + x = 43/4 ;
making the denominator same by taking LCM as 8 ,
we get ;
⇒ 15/8 + 11/8 + 18/8 + 8x = 43/4
⇒ 15/8 + 11/8 + 18/8 + 8x/8 = 43/4
⇒ 15 + 11 + 18 + 8x = 8 × 43/4 ;
⇒ 44 + 8x = 86 ;
⇒ 8x = 86-44 = 42 ;
⇒ x = 42/8 = 5.25
Therefore , Pablo still needs to cover 5.25 miles to reach his weekly goal .
The given question is incomplete , the complete question is

A construction company bought a new bulldozer for $125,000. The bulldozer depreciates exponentially and after 2 years the value of the bulldozer is $80,000. What is the value at year 2. 5 and 5Let V0 be the initial value of the bulldozer, and k be the depreciation rate. We know that the value of the bulldozer after 2 years is V2 = V0 * e^(-k * 2) = 80000.
So, k = -ln(V2/V0) / 2.
The value of the bulldozer at year 2.5 can be calculated as:
V2.5 = V0 * e^(-k * 2.5)
The value of the bulldozer at year 5 can be calculated as:
V5 = V0 * e^(-k * 5)
Plugging in V0 = 125000 and k = -ln(V2/V0) / 2, we get:
V2.5 = 125000 * e^(-k * 2.5) = 93593.67

if m<DEC= (12x-3)°, m<BCE= (7x-26)°, and m<DAE= 72°, find each angle measure.
The angle of each measure is:
m<DEC= 129°
m∠BCE = 51°
m∠ADE = 57°
m∠EDB = 123°
m∠DBC = 57°
What is meant by angle of measure in triangle?Angle of measure is the measure of an angle formed by two rays with a common endpoint. Angle of measure is important to many mathematical and scientific fields, including geometry, trigonometry, and physics.
In geometry, angles are used to define shapes and measure the size of an object. For example, angles are used to determine the angles of a triangle, or the angles between the sides of a rectangle. Angle of measure is also important in trigonometry, as it is used to calculate the lengths of sides and angles in a triangle, as well as the area of a triangle.
Angle of measure is also used in engineering, navigation, and surveying. When designing a building or structure, angles are used to determine the strength and stability of the structure, as well as the angles of the beams and walls. In navigation, angles are used to calculate the direction of a ship or aircraft. Finally, in surveying, angles are used to measure the angles between points on a map or a landscape.
Given,
m∠DEC= (12x-3)°, m∠BCE= (7x-26)°, and m∠DAE= 72°
∠DEC+∠BCE = 180°
12x-3+7x-26 = 180°
19x - 29 = 180°
19x = 180+29
x = 209/19
x = 11
Substitute x=11 in m∠DEC= (12x-3)°, we get
m∠DEC= 129°
Substitute x=11 in m∠BCE= (7x-26)°, we get
m∠BCE = 51°
To find m∠ADE,
m∠ADE + m∠DAE + m∠DEA=180°
m∠ADE + 72° + 51° = 180°
m∠ADE = 57°
To find m∠EDB,
m∠EDB + m∠ADE=180°
m∠EDB = 180° - 57°
m∠EDB = 123°
To find m∠DBC,
m∠DBC = m∠ADE are corresponding angles, so
m∠DBC = m∠ADE = 57°

By drawing a suitable line find the solution to
2-x^3= 4x+3
If right answer, ill award brainliest and 15 points x
The solution to the equation 2-x³ = 4x + 3 is x=1.
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
To find the solution to the equation 2-x³=4x+3, we can set the two sides of the equation equal to each other and solve for x.
2-x³ = 4x + 3
x³ - 4x - 1 = 0
To solve this equation, factor it or use the cubic formula.
One possible solution is x = 1, which can be verified by substituting it back into the original equation.
Another way to find the solution graphically, we can plot the graphs of y = 2-x^3 and y = 4x+3 on the same coordinate plane. The points at which the two graphs intersect are the solutions to the equation.
The graph of y = 2-x^3 is a downward facing parabola and the graph of y = 4x+3 is a line with slope 4 and y-intercept 3.
The intersection point of the parabola and the line is the solution x=1
It is not possible to find the other solutions graphically because the parabola doesn't intersect with the line again.

For the given graph, the slope is 2/9, t the U.S. box office revenue in 2018 is 12 billion.
Given a graph depicting approximations of US box office earnings (in billions of dollars) from 2000 to 2012, what would you conclude?
We must calculate the graph's slope and y-intercept.
In order to overcome the issue, we are employing the point-slope form. Two points are obtained from the graph: (x1,y1) = (0,8) and (x2,y2) = (9, 10).
Consequently, slope is m = y2 - y1 / x2 - x1
⇒ 10 - 8/ 9 - 0 = 2/9
This is the graph's straight line's slope.
The point-slope form is given by y-y1 = m. (x-x1)
Meaning: y - 8 = m(x - 0)
The line's equation is then y = 2x/9 + 8, with 8 serving as the y-intercept.
• In this case, the y-intercept provides the beginning value, or 8 when x = 0. Here, the year 2000 is represented by the number 0, and the U.S. box office took in $8 billion in that year.
2 • The graph's straight line shape and slope (m) indicate that the U.S. box office's revenue is rising at a steady rate of $2 billion every two years. 2 year 9 is on the x-axis.
• Using the equation, y = 2, we may get the precise income in any year from 2000 through 2012.
The x axis in the graph corresponds to the year;
hence, the point at x = 0 denotes the year 2000 and the one at x = 12 denotes the year 2012.
In order to get the income for 2018, we must determine the value of y when x equals 18.
The formula is y = 2x/9 + 8
y = 2(18)/9 + 8
y = 12
That is, 12 billion dollars will be made at the U.S. box office in 2018.

What is a trapezoid?An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.
A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.
The altitude is the measurement of the angle perpendicular to the parallel sides.
The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.
We know the midsegment of a trapezoid is half of the sum of the two parallel sides.
Therefore, {(3x + 11) + (10x - 12)}/2 = 45.
3x + 11 + 10x - 12 = 90.
13x - 1 = 90.

b.) suppose we select three letters from an extremely large pool of letters, where the number of a's, b's, ... z's are all the same. what is the probability that all three will be identical?
The probability that all three letters are identical is the product of the probability that each individual letter is identical, which is (1/26) * (1/26) * (1/26) = (1/26)^3.
The probability that all three letters selected are identical would be (1/26)^3, assuming that the pool of letters contains an equal number of each letter of the alphabet (a, b, c, ..., z) and that each letter is selected independently and with replacement. This is because there is only a 1 in 26 chance of selecting any given letter on the first draw, and the same is true for the second and third draws. Since all three draws are independent, the probability that all three letters are identical is the product of the probability that each individual letter is identical, which is (1/26) * (1/26) * (1/26) = (1/26)^3.

Is a^6 + b^6= (a^2 +b^2)(a^4-a^2b^2+b^2 an identity? Explain or show your reasoning.
a^6 + b^6= (a^2 +b^2)(a^4-a^2b^2+b^2) is an identity. The reasoning is done below.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given an expression a^6 + b^6= (a^2 +b^2)(a^4-a^2b^2+b^2) we need to assure if its right or not
Let "x" = a² and "y" = b² thus the equation
x³ + y ³ = ( x + y)(x² + y² - xy)
Method 1Take L.H.S.
=> x³ + y³ = (x + y)³ - 3xy (x + y)
» Take (x + y) common
=> (x + y) [(x + y)² - 3xy (1)]
=> (x + y) [(x² + 2xy + y²) - 3xy]
Because (a + b)² = a² + 2ab + b²
=> (x + y) (x² + y² + 2xy - 3xy)
=> (x + y) (x² + y² - xy)
L.H.S. = R.H.S.
Method 2Take R.H.S.
=> (x + y) (x² - xy + y²)
=> x(x² - xy + y²) + y(x² - xy + y²)
=> x³ - x²y +xy² + x²y - xy² + y³
=> x³ + y³
L.H.S. = R.H.S.
therefore, a^6 + b^6= (a^2 +b^2)(a^4-a^2b^2+b^2) is an identity .

When the function f(x) is divided by 3x + 1, the quotient is 2x^2 + 2x - 9 and the remainder is 7. Find the function f(x) and write the result in standard
form.
Answer:
To find the function f(x), we need to use the Remainder Theorem. The Remainder Theorem states that if we divide a polynomial by x - a, the remainder will be equal to the value of the polynomial at x = a.
We know that f(x) divided by 3x + 1 leaves a remainder of 7, so we can set up the equation:
f(x) = (3x + 1)(2x^2 + 2x - 9) + 7
Expanding the left side of the equation, we get:
f(x) = 6x^3 + 2x^2 - 27x - 9 + 7
Simplifying, we get:
f(x) = 6x^3 + 2x^2 - 27x + 2
The function f(x) is in standard form.
Answer:
When the function f (x) is divided by 3x – 1, the quotient is 2x² – 3x + 6 a

Samuel buys 3 bottles of juice that each have an original price of 2.80. He uses a coupon for 35% off. Then, he is changed sales tax at a rate of 6.5%. How much does Samuel pay 3 bottles of juice?
Samuel pay 5.81 for the 3 bottles of juice.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
Samuel buys 3 bottles of juice that each have an original price of 2.80.
And, He uses a coupon for 35% off. Then, he is changed sales tax at a rate of 6.5%.
Here, The original cost of 3 bottles of juice = 3 × 2.80
= 8.40
Now, He uses a coupon for 35% off.
Hence, The off price = 35% of 8.40
= 35/100 × 8.40
= 2.94
So, The amount of 3 bottles of juice = 8.40 - 2.94
= 5.46
And, He is changed sales tax at a rate of 6.5%.
Thus, The sales tax on bottles = 6.5% of 5.46
= 6.5/100 × 5.46
= 0.35
Thus, The actual amount of 3 bottles of juice = 5.46 + 0.35
= 5.81

You buy 1 balloon and 1 banner for $3. Your friend buys 5 balloons and 2 banners for $9. What is the cost of each balloon? of each banner?
We can start solving the problem using systems of equations. Let x be the cost of each balloon and y be the cost of each banner. We know from the problem that:
1x + 1y = 3 (the cost of 1 balloon and 1 banner is $3)
5x + 2y = 9 (the cost of 5 balloons and 2 banners is $9)
We can use the first equation to solve for one of the variables in terms of the other, and substitute that into the second equation. Then we can solve for the remaining variable.
From equation 1:
y = 3 - x
We can substitute this into equation 2:
5x + 2(3 - x) = 9
Which simplifies to:
5x + 6 - 2x = 9
3x = 3
x = 1
So each balloon costs $1
We can now substitute x=1 in the first equation:
1*1 + 1y = 3
y = 2
So each banner costs $2
Step-by-step explanation:
Let us assume the cost of
balloon be x banner be yIn first case , cost of 1 1 balloon and 1 banner is $3 . We can set up a equation as ,
1*x + 1*y = 3
x + y = 3 . . . . . (i)
In second case, cost of 5 balloons and 2 banners is $9 . So ,
5*x + 2*y = 9
5x + 2y = 9 . . . . . (ii)
From equation i and ii , we have ,
5(3-y) + 2y = 9
15 - 5y + 2y = 9
15 - 3y = 9
3y = 15 -9
3y = 6
y = 2
And we had ,
x + y = 3
x + 2 = 3
x = 3 - 2
x = 1
Hence,
cost of balloon= x = $1cost of banner= y = $2and we are done!
