43 is equivalent to 64(1/3)
What are equivalent numbers?Equivalent is different from equal. Equal means same in all aspects, whereas equivalent means similar but not identical.
For example, 2 is said to be equal to 2 but equivalent to 1 + 1.
Given that, if a=b(1/n) is equivalent to an=b then 43 is equivalent to
If we see the number 43, then converting it according to given pattern
4ⁿ(1/n)
Here, n = 3
So, 43 = 4³(1/3) = 64(1/3)
Hence, 43 is equivalent to 64(1/3)

How to determine the true statement?From the question, we have the following parameters that can be used in our computation:
Trapezoid PQRS
The transformation is given as
Reflection across the y-axisRotation 90 degrees clockwiseAs a general rule of transformation, reflection and rotation are rigid transformations and they do not change the size and angles in a shape
This means that we get a congruent figure to that figure after the transformations
Thus, when PQRS is reflected and rotated 90° about the origin to form trapezoid KLMN, the trapezoid KLMN is congruent to trapezoid PQRS.
⇒ By the definition of congruence,
The corresponding sides and angle of trapezoid KLMN are congruent to that of trapezoid PQRS.
⇒ ∠P ≅ ∠K, ∠Q ≅ ∠L, ∠R ≅ ∠M and ∠S ≅ ∠N
⇒ Option D) is correct.
Note: KMLN is a trapezoid ⇒ Sum of the angle measures of trapezoid P'Q'R'S' is also 180°
Option A) is incorrect.
Since, trapezoid KMLN is congruent to trapezoid PQRS.
⇒ Option B) is incorrect.
We know that if two shapes are congruent then their area must be equal.
⇒ Area of trapezoid KMLN = Area of trapezoid PQRS
Thus, Option C) is incorrect.

a 10-ft vertical post casts a 20-in shadow at the same time a nearby cell phone tower casts a 125-ft shadow. how tall is the cell phone tower?
Answer:
750 ft
Step-by-step explanation:
the 2 situations are similar ( both right triangles ) with corresponding sides being in proportion.
let h be the height of the cell phone tower
We require the dimensions to be the same, using the conversion
1 foot = 12 inches , then
10 ft = 10 × 12 = 120 in
125 ft = 125 × 12 = 1500 in
then we obtain
[tex]\frac{h}{1500}[/tex] = [tex]\frac{120}{20}[/tex] = 6 ( multiply both sides by 1500 to clear the fraction )
h = 1500 × 6 = 9000 in ( divide by 12 to convert to ft )
h = 9000 in ÷ 12 = 750 ft
that is the cell phone tower is 750 ft tall.

Which systems have infinite solutions? check all that apply. y = 0.5x 2.75 and 2y = x 2.75 y = 0.5x 2.75 and y – 0.5x = 2.75 y = 0.5x 2.75 and 0.5x y = 2.75 y = 0.5x 2.75 and y = 0.5(x 5.5) y = 0.5x 2.75 and y = –2(–0.25x ) 2.75
Both equations y = 0.5x + 2.75 and y – 0.5x = 2.75 are equal. Hence, these systems will have infinite solutions. Hence, Option a is the most suitable answer to this question.
The system of equations having an infinite number of solutions must be the same.
In option a -
we have, y = 0.5x + 2.75 and 2y = x + 2.75
Rewriting the second equation 2y = x + 2.75 in slope-intercept form, we get,
2y = x + 2.75
y = x/2 + 2.75/2
y = 0.5x + 1.375
Both equations are not similar.
Hence this option is not the right choice.
Similarly, we will check for option b -
we have, y = 0.5x + 2.75 and y – 0.5x = 2.75
From the second equation y - 0.5x = 2.75, this can be expressed as y = 0.5x + 2.75 in the slope-intercept form.
Here, we get both equations equal.
Thus, y = 0.5x + 2.75 and y – 0.5x = 2.75 will have infinite solutions.
Similarly, checking for other options, we do not get any similar equations.
Hence, option b is the correct answer to this question.

Answer:
first equation = red line

Step-by-step explanation:
First, we solve for y for both equations
4x + 2y = -12
2y = -12 - 4x
2y = -4x -12
y = -2x - 6
3x - 5y = -35

gerardo is 9 feet away from his car when he begins walking directly away from his car at a constant speed of 3 feet per second. if gerardo is 24 feet from his car, how many seconds have elapsed since he started walking away from his car?
The time that has elapsed since Gerardo started walking away from car will be equal to 5 seconds.
We solve this problem by converting it into a linear equation that has three variables in it. Since we have distance, time and speed the three variables will be d, t and s respectively. The expression which shows the distance of Gerardo will be expressed as
d = (s×t) + 9; we have the constant as 9 because Gerardo was 9 feet away from his car.
Now, we have the distance as d = 24 feet and the speed is constant that is equal to 3 feet per second and we need time which will be
24 = (3×t) + 9
15 = 3×t
=> t = 15/3
=> t = 5 seconds

How much work is done on a car if you push with 100 Newtons of force but it does not move?
Answer:
0 Joules (No work)
Step-by-step explanation:
The amount of work done on an object is equal to the force applied to the object times the distance over which the force is applied. In this case, the force applied to the car is 100 newtons, but the car does not move, so the distance over which the force is applied is 0 meters.
Therefore, the amount of work done on the car is 100 newtons * 0 meters = 0 joules. This means that no energy has been transferred to or from the car as a result of the force applied to it.

Answer:
6i-4
Step-by-step explanation:
To simplify the expression 4i+(8-3i) - 12+√-25, you can start by combining like terms.
First, you can combine the terms 4i and -3i to get 1i. You can also combine the constants 8 and -12 to get -4.
So, the expression becomes 1i - 4 + √-25.
Next, you can simplify the square root. √-25 is the same as √(-25) which is the same as √(5*-5), which is the same as 5√(-1). √(-1) is equal to i, so 5√(-1) is equal to 5i.
Therefore, the final simplified form of the expression is 1i - 4 + 5i, which is equal to 6i - 4.
