Quadrilaterals ABCD and EFGH are similar. If the perimeter of the quadrilateral ABCD is equal to 4y² what is the perimeter of the quadrilateral EFGH?
Answer:
Can't be determined.
Step-by-step explanation:
From the fact that the quadrilaterals are similar:
Corresponding sides are in proportion and
Corresponding angles are congruent.
We can't create a proportion, so there's nothing else that we can determine.
Answer:
Below.
Step-by-step explanation:
Similar figures have the same size but not necessarily the same size.
The respective sides will be in the same ratio in a similar figure.
So from the information given you can't say what the measure of the perimeter of quadrilateral EFGH is. All you can say is the ratio of the perimeters is the same as the ratio of the respective sides. If the ratio is 1:2 for example then the perimeter of EFGH is 2*4y^2 = 8y^2.
If i make $8.00 per hour and work 6 hours a day 5 days per week how much would my check be bi-weekly?
Answer:
480$
Step-by-step explanation:
Bi-weekly means every other week. So it is 6 times 5, because u work 30 hours a week. Than 30 (hours) times 8 (money per hour). This is 240 a week. So 240 times 2 is 480.

THIS IS THE COMPLETE QUESTION BELOW;
The probability of pulling a green marble out of a bag of colored marbles is 2:5. If you were to pull colored marbles out of the bag one at a time, and putting the marble back each time for 600 tries, approximately how many time would you select a green marble?? ( explanation too) 7th grade Math
Answer:
We would approximately pick a green marble 240 times
Step-by-step explanation:
Given from the question the probability of pulling a green marble out of a bag of colored marbles is 2:5
Let us denote the number of trials as X
Now the approximately number of times a green marble can be selected would be
=2/5 times
From the question we are given 600 trials
which implies our x=600
Therefore, the number of times we would pick a green marble is:
2/5 × 600 times
≈ 240 times
Therefore, we would approximately pick a green marble 240 times
Which figure shows a line of reflectional symmetry for the letter T? A letter T is folded at the horizontal line. A letter T is folded diagonally. A letter T is folded vertically through the middle. A letter T is folded diagonally through its center.
Answer:
A letter T is folded vertically through the middle.
Step-by-step explanation:
Reflectional symmetry refers to the symmetry of line that divides the given shape into two equal halves. The halves represent the mirror reflection of each other. The line of symmetry is drawn to show the reflection and it acts as a mirror. For the letter 'T', the reflectional symmetry will be drawn vertically in the middle of the letter. The line divides the letter into two equal halves with mirror images.
The figure that will depict a line of reflectional symmetry of letter T would be: A letter T folded vertically through the middle.
What is a Line of Reflectional Symmetry?A line of reflectional symmetry can be described as an imaginary line that divides a figure into two halves in such a way that each of the halves are a mirror image of the other.
When a line divides letter T vertically, two mirror images are created.
Thus, the figure that will depict a line of reflectional symmetry of letter T would be: A letter T folded vertically through the middle.

When shopping for accessories for her action camera, Giana found an advertisement for a replacement battery. The advertisement includes
the given graph of a function to represent the charge remaining in the battery after streaming x hours of video.
Answer:
The correct options are;
The equation of the function is 2·y = -25·x + 200
The equation of the function is y = -25/2·x + 100
The x-intercept of the function is (8, 0)
Step-by-step explanation:
From the graph of the function, the y-intercept is observed at (0, 100), the x-intercept occurs at (8, 0)
Therefore, we have the slope, m given by the following relation
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Where:
y₁ = 100
x₁ = 0
y₂ = 0
x₂ = 8
Which gives;
[tex]m =\dfrac{0-100}{8-0} = -12.5[/tex]
The equation in slope can be found as follows
y - 100 = -12.5×(x - 0)
y = -12.5·x + 100 = -25/2·x + 100
Multiplying by 2 gives;
2·y = -25·x + 200
25·x + 2·y = 200
Therefore, the correct options are;
The equation of the function is 2·y = -25·x + 200
The equation of the function is y = -25/2·x + 100
The x-intercept of the function is (8, 0).
Answer:
The x-intercept for the function is (8,0).
The equation of the function is 25x + 2y = 200.
The equation of the function is y =-25/2 x + 100.

List the sides of ∆XYZ in order from shortest to longest if m∠X = 51, m∠Y = 59, and m∠Z = 70
Step-by-step explanation:
Angles and sides go hand-in-hand. Although I don't see the actual triangle that's used, and that can affect my answer, the side opposite of the shortest angle will be the shortest, the side opposite of the middle angle will be the middle, and the side opposite the largest angle will be the largest. For example, if the shortest angle (m∠X = 51) is the top vertex, the base side will be the shortest.

Find the height, x, of the triangle. A. 30 B. 40 C. 50 D. 60
Answer:
The correct option is;
A. 30
Step-by-step explanation:
Given that the perpendicular bisector forms two other right angled triangles, we have;
For the larger right angled triangle, hypotenuse length = 100
For the smaller right angled triangle, hypotenuse length = 90
We note that;
y² = x² + 10²
z² = x² + 90²
100² = z² + y ²
Therefore we have;
100² = x² + 10² + z² = x² + 10² + x² + 90² = 2·x² + 90² + 10²
10000 = 2·x² + 8200
2·x² = 10000 - 8200 = 1800
x² = 1800/2 = 900
x = 30
A polynomial has x-intercepts of 3, 0, and –1, and passes through the point (1, –8). Which of the following functions could represent this graph? 1. x3 – 2x2 – 3x 2. x2 – 2x – 3 3. 2x2 – 4x – 6 4. 2x3 – 4x2 – 6x
Answer:
option 4
Step-by-step explanation:
Given the x- intercepts say x = a, x = b, x - c then the corresponding factors are
(x - a), (x - b), (x - c) and the polynomial is the product of the factors
Here the x- intercepts are x = 3, x = 0, x = - 1, thus the factors are
(x - 3), (x - 0), (x - (- 1) , that is
(x - 3), x and (x + 1) , then
y = ax(x - 3)(x + 1) ← where a is a multiplier
To find a substitute (1, - 8) into the equation
- 8 = a(1 - 3)(1 + 1) = - 4a ( divide both sides by - 4 )
a = 2, thus
y = 2x(x - 3)(x + 1) ← expand factors using FOIL
= 2x(x² - 2x - 3) ← distribute by 2x
= 2x³ - 4x² - 6x
Answer:
D) 2x3 – 4x2 – 6x

Answer:
20 or 21 stakes
Step-by-step explanation:
It would be 20 if you were not able to use the extra wood after cutting two 5.5 foot long segments from each lumber. If you can use the extra 1 foot from each lumber then you would have an extra 10 feet of lumber which you could get one 5.5 foot long stake from.
The number of stakes will be 22.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that 5.5 feet long can be cut from 10 lengths of lumber each 12 feet long.
The total length is calculated as:-
Total length = 12 x 10 = 120 feet
Number of stakes = 120 / 5.5 = 21.81 ≅ 22
Hence, the number of stakes is 22.

The owners of the car wash want to cut back their water usage during a drought and decide to close the car wash early two days a week. The amount of decrease in water used is modeled by D(x) = x3 + 2x2 + 15, where D is the amount of water in cubic feet and x is time in hours.
Write a function, C(x), to model the water used by the car wash on a shorter day
Answer:
The second option.
Step-by-step explanation:
We are trying to find what is W(x) - D(x).
(4x^3 + 6x^2 - 11x + 7) - (x^3 + 2x^2 + 15)
= 4x^3 - x^3 + 6x^2 - 2x^2 - 11x + 7 - 15

A function, C(x), to model the water used by the car wash on a shorter day will be 3x³ + 4x² - 11x - 8
What is an equation?
An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
The water usage at a car wash is modelled by the equation W(x) = 4x³ + 6x² − 11x + 7, where W is the amount of water in cubic feet and x is the number of hours the car wash is open. The amount of decrease in water used is modelled by D(x) = x³+ 2x² + 15, where D is the amount of water in cubic feet and x is time in hours.Now the amount of water is cut from the total water usage so to find out the new model c(x) we need to subtract the decrease in water from the total water usage.
We are trying to find what
C(x) = W(x) - D(x)
C(x) = ( 4x³ + 6x² − 11x + 7, ) - ( x³ + 2x² + 15 )
C(x) = 4x³ - x² + 6x² - 2x³ - 11x + 7 - 15
C(x) = 3x³ + 4x² - 11x - 8

Since the triangle isosceles < E is also the same as < D
Let < E also be x
Angles in a triangle add up to 180°
x + x + 102 = 180
2x = 180 - 102
2x = 78
Divide both sides by 2
x = 39°
