The condition for the figure to be similar is that; DE = FD
What are similar figures?Similar figure are zoomed in or zoomed out (or just no zoom) version of each other. They are scaled version of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.
In the problem, the ratio should be CD/DE = GD/DF
We can also write the ratios of the corresponding sides as:
CD/DE = GD/DF
Therefore, CE and GF are similar
Thus, the condition for the figure to be similar is that;

The x-intercept is at point (30,0) and the y-intercept is at point (0,25). The graph of the equation is attached below.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that Short-sleeved shirts cost $10 each.
The Long-sleeved shirts cost $12 each.
The total budget is $300.
The given equation is 10x + 12y = 300
where x is the number of short-sleeved shirts and y is the number of long-sleeved shirts.
We have, 10x + 12y = 300
Substitute the value x = 0
10(0) + 12y = 300
12y = 300
y = 25
So, the y-intercept will be at 0,25).
Substitute y = 0
10x + 12(0) = 300
10x = 300
x = 30
So, the x-intercept is at point (30,0).
The x-intercept is at point (30,0), that means the number of short-sleeved shirts is 30. The y-intercept is at point (0,25), that means the number of long-sleeved shirts is 25.

One pound of grout is enough to grout a tiled area that is 110 sq. ft. Alyssa’s kitchen counter is made up of two rectangular segments. One is 10.3 ft by 2.5 ft, and the other is 3.1 ft by 2 ft. Which expression represents the number of pounds of grout Alyssa will need?
Answers
By taking the quotient between the area that one pound covers and the area of the kitchen, we conclude that Alyssa will need 0.29 pounds of grout.
How many pounds will Alyssa need?We know that one pound of grout covers a total of 110 square feet.
Alyssa's kitchen is made of two rectangular segments, one that measures 10.3ft by 2.5 ft, then the area of this rectangle is:
10.3ft*2.5ft = 25.75 ft²
The other rectangle has dimensions of 3.1ft by 2ft, so the area is:
3.1ft*2ft = 6.2ft²
The total area is:
25.75 ft² + 6.2ft² = 31.95 ft²
Now, with one pond of grout, they can cover 110 ft², then the number of pounds that Alyssa needs is:
N = 31.95 ft²/110 ft² = 0.29
Alyssa will need 0.29 pounds of grout.

The range of the function N(t) is [20.25, ∞). The correct option is D.
What is the range of the function?A function's range is the set of possible output values. For example, the range of the function f(x)=x² on the domain of all real numbers (xR) is the non-negative real numbers, which can be written as f(x)0 (or [0,] in interval notation).
In this question, we have been given that an online streaming service that offers TV shows, documentaries, and movies charges an initial fee of $ 20.25 and an additional monthly membership fee of $3.75.
The total cost, N(t), for a member after t months can be expressed with the function N(t) = 3.75t + 20.25
As t is the number of months, t can take values from 0 to infinity.
For t = 0 years,
N(0) = 3.75(0) + 17.25
N(0) = 0 + 17.25
N(0) = $17.25
For x tends to ∞, the value of function would be ∞. The range will be (20.25,∞).

what is the width of the pool?
(Show work)
Answers
Answer:
The perimeter P of a rectangular is given by formula P=2l+2w where l is the length and w is width of rectangle.Given that perimeter is 56 meters and length's 16 meters. Substituting values in formula,subtract 32 from both sides -⇒24=2w w=12width of rectangular pool is 12 meters.Hence, the answer is 12.Answer:
Perimeter = 2(l+b)
Perimeter = 116
width = x
length = 3x
116 = 2(3x+ x)
116 = 6x+2x
116 = 8x
x = 116/8
x = 14.5
You can verify answer by inputing value of x to see if perimeter is = 116 :
perimeter = 2(l+b)
116 = 2(3(14.5) + 14.5)
116 = 2(43.5 + 14.5)
116 = 87 + 29
116 = 116

Answers
The line A and line B are perpendicular to each other.
What is defined as the perpendicular lines?Perpendicular lines are defined in geometry as two lines which meet or intersect at right angles (90°). The term "perpendicular" is derived from the Latin phrase "perpendicularis," which means "a plumb line."The following are the two important properties of perpendicular lines.These lines are always at right angles when they intersect.If two lines seem to be perpendicular to each other, they are parallel and will never intersect.For the given ques, the graph of line A and line B are given.
The relation of slope of two perpendicular lines is their product of slope is -1.
Line A: select two point lying on the line A.
(2, 3) and (1, 1)
slope = m = (2 - 1)/(3 - 1)
m₁ = 1/2
Line B: select two point lying on the line B.
(8, 0) and (0, 4)
slope = m = (0 - 4)/(8 - 0)
m₂ = -4/8
m₂ = -1/2
Now, multiply both slopes.
m₁ x m₂ = 1/ 2 x -1/2
m₁ x m₂ = - 1
Thus, the line A and line B are perpendicular to each other.
