What is word problem?A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
From the question,
Can A is 9 parts of blue 1 part yellow= 90% blue, 10% yellow
Can B is 20% blue, 80% yellow.
let
A + B = 8 Liters
90% A + 20% B = 50% (Blue)
10% A + 80% B = 50% (Yellow)
resolving
90% A + 20% B = 10% A + 80% B
80% A = 60% B
Go back to A + B = 8 and solve for one of the variables.
B = 8 - A
80% A = 60% (8 - A)
80% A = 480% - 60% A
140% A = 480%
A = 3 43 liters
B = 8 - A = 4.57 liters
Hence, 3.43 liters of Can A, and 4.57 liters of Can B should be used.

A classic counting problem is to determine the number of different ways that the letters of "recommend " can be arranged.
The number of different ways that the letters of "recommend" can be arranged is 90720.
What is arrangement?
Generally speaking, an arrangement of objects is just a collection of them. A combination (order is ignored) or permutation is used to determine the number of "arrangements" of the components (order is significant). An arrangement is a group of hyperplanes that divides a space into cells.
If there are n different objects in the system then the number of different ways of arrangement of n objects is n!
If the repetition of the objects are allowed in the system the number of different ways of arrangement is -
n! / (no. of repetition of object 1)! .... (no. of repetition of object r)!
Total number of letters in the word "recommend is 9.
The number of different ways of arangement of the 9 letters is 91
The repetition of letter "e" is 2 and repetition of letter "m" is 2.
The number of different ways that the letters of "recommend" can be arranged is -
9! / 2! × 2!
(9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1) / (2 × 1) × (2 × 1)
(9 × 8 × 7 × 6 × 5 × 3 × 2 × 1)

Write the first five terms of the arithmetic sequence with the first term a1=7 and the common difference d=4
Answer:
7, 11, 15, 19, 23
Step-by-step explanation:
Since the common difference is 4 each successive term is 4 more than the previous term
If we let aₙ be the nth term,
a₁ = 7
a₂ = 7 + 4 = 11
a₃ = 11 + 4 = 15
a₄ = 15 + 4 = 19
a₅ = 19 + 4 =23
The first five terms are: 7, 11, 15, 19, 23
We can also use the generalized formula for the nth term:
aₙ = a₁ + d(n - 1)
where a₁ = first term
d = common difference
Plugging in the known values we get
aₙ = 7 + 4(n- 1)
aₙ = 7 + 4n - 4
aₙ = 3 + 4n
Substituting n = 1, 2, 3, 4, 5 into the above equation will yield the same values

Question 2 Multiple Choice Worth points} (02.09 MC) position-time graph is shown below: Position Vs Time 0 L Time (seconds) Which statement accurately describes the speed of the object in the graph above over the 10 seconds? Speed is decreasing Speed is constant Speed is not constant; Object is at rest
The most accurate statement is "Speed is decreasing." This means that the object is moving at a decreasing velocity over the 10 seconds.
What is the Speed is constant?
When we say that the speed of an object is constant, it means that the magnitude of the velocity of the object remains unchanged over time. In other words, the object is moving at a steady pace and its speed does not vary.
The statement "Speed is not constant; Object is at rest" is not accurate.
From the position-time graph, it is clear that the object is moving in one direction and its position is changing with time. Hence, the object is not at rest.
Furthermore, the slope of the position-time graph gives us the velocity of the object, and from the graph, it appears that the slope is changing with time, which means that the speed is not constant. Hence, the statement that "Speed is constant" is also not accurate.
Hence, the most accurate statement is "Speed is decreasing." This means that the object is moving at a decreasing velocity over the 10 seconds.

Suppose that a particle moving along the x-axis encounters a resisting force that results in an acceleration of a =-=-0.10 V v. Given that x = 0 cm and v = 36 cm/s at time t = 0, find the velocity v and position x as a function of t for t 2 0. v= 2 cm/s Edit C x= 2 cm
The velocity of the particle v as a function of time t is given by v(t) = 36 - 0.10 * t^2 cm/s and the position x as a function of time t is given by x(t) = 36 * t - 0.05 * t^3 cm.
The problem states that at time t = 0, the particle has an initial velocity of v = 36 cm/s and is located at x = 0 cm. The particle is accelerating with a=-0.10 V v. This means that the velocity of the particle is changing by -0.10 V v each second. This can be expressed in terms of the time t as v(t) = 36 - 0.10 * t^2 cm/s. The position of the particle at any time t can be expressed as x(t) = x0 + v0 * t + 1/2 * a * t^2, where x0 is the initial position and v0 is the initial velocity. In this case, x0 = 0 and v0 = 36, so the position of the particle at any time t can be expressed as x(t) = 36 * t - 0.05 * t^3 cm. This means that the particle will move away from the origin (x=0) and its velocity will decrease each second.

Answer:
1. sin∠EDA is equal to sin∠EBC
2. sin∠CEB is not equal to sin∠EBC
3. cos∠BEC is equal to sin∠EBC
4. cos∠ADE is not equal to sin∠EBC
5. sin(90 - m∠EBC) is not equal to sin∠EBC
6. cos(90 - m∠EDA) is equal to sin∠EBC
Step-by-step explanation:
From inspection of the given diagram, ∠EAD = ∠ECB = 90°.
According to the vertical angles theorem, ∠BEC = ∠DEA.
According to AA similarity theorem, ΔADE ~ ΔCBE
Therefore, ∠EDA = ∠EBC.
This means that:
sin∠EDA is equal to sin∠EBCsin∠CEB is not equal to sin∠EBC[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]
Since cos∠BEC = CE/BE and sin∠EBC = CE/BE then:
cos∠BEC is equal to sin∠EBC.As ∠BEC ≠ ∠ADE then:
cos∠ADE is not equal to sin∠EBC.As sin(90° - x) = cos(x) then sin(90 - m∠EBC) = cos∠EBC.
As cos∠EBC ≠ sin∠EBC then:
sin(90 - m∠EBC) is not equal to sin∠EBCAs cos(90° - x) = sin(x) then cos(90 - m∠EDA) = sin∠EDA.
As sin∠EDA = sin∠EBC then cos(90 - m∠EDA) = sin∠EBC.
Hence:
cos(90 - m∠EDA) is equal to sin∠EBC.find all $r$ for which the infinite geometric series \[2 6r 18r^2 54r^3 \dotsb\]is defined. enter all possible values of $r,$ as an interval.

Answer: Let's call the increase from 15 to 20 as "z".
So, 20 is (z / 15) * 100% greater than 15, or x = (z / 15) * 100.
And, 15 is (z / 20) * 100% less than 20, or y = (z / 20) * 100.
Since z is the same in both equations, we can set the two equations equal to each other:

The equation of the line that is perpendicular to 5x-8y=-6 and passes through (4,-4) is y = (-8/5)x + 16/5.
What are Parallel lines?Parallel lines are two or more lines in a coordinate plane that are equidistant from each other at all coordinates.
The given line can be rewritten in slope-intercept form as y=(5/8)x+(3/4), where the slope is 5/8. So, any parallel line will also have a slope of 5/8.
Using the point-slope form of a line, we can write the equation of the line as:
y - (-4) = (5/8)(x - 4)
Simplifying, we get:
y = (5/8)x - 23/8
Therefore, the equation of the line that is parallel to 5x-8y=-6 and passes through (4,-4) is y = (5/8)x - 23/8.
The slope of the given line is 5/8, so the slope of any line perpendicular to it will be -8/5.
y - (-4) = (-8/5)(x - 4)
Simplifying, we get:
y = (-8/5)x + 16/5
Therefore, the equation of the line that is perpendicular to 5x-8y=-6 and passes through (4,-4) is y = (-8/5)x + 16/5.

If we are to write the following polynomial in descending powers of the variable and with no missing powers 3x^3 -70, it would be 3x^3 - 70 + 0x^2 + 0x + 0
What is a Polynomial?A polynomial is an equation made up of coefficients and indeterminates that uses only the addition, subtraction, multiplication, and powers of positive-integer variables.
Hence, it can be seen that descending order is basically when the power of a term decreases for each succeeding term. For example, x3 + x2 + x or 2 x4 + 3 x2 + 7 x are arranged in descending order. Descending order is more commonly used.
The polynomial in descending powers of the variable with no missing powers is:
3x^3 - 70 = 3x^3 - 70 + 0x^2 + 0x^1 + 0x^0
= 3x^3 - 70 + 0x^2 + 0x + 0

The synthetic division process involves dividing the polynomial by a linear factor in a compact manner. In this case, we are dividing the polynomial 4x^4 - 9x^3 + 14x^2 - 12x - 1 by x - 1.
To perform synthetic division, we first write the coefficients of the polynomial in a row and add a zero at the end. Then, we divide the first coefficient (4) by the leading coefficient of the divisor (x - 1), and write the result (4) above the next coefficient (-9). Next, we multiply the divisor (x - 1) by the first quotient (4) and subtract the result from the row. The new row of coefficients is the result of this subtraction. Repeat this process until all coefficients have been processed or a remainder is left.
Here is the process:
