The triangles ΔPQR ≈ ΔXYZ are similar by Angle-Angle Similarity.
What are similar triangles?If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.
Similar figures are items that feature more than two figures that are the same shape but different sizes.
Given two triangles, ΔPQR and ΔXYZ
both the triangles are right triangles,
∠P = ∠Z = 90°
and given ∠R = ∠Y = 62°
A triangle is said to be comparable to another triangle if any two of its three angles are equal to any two of its three angles.
From the above-described figure
ΔPQR ≈ ΔXYZ
so triangles are similar to Angle-Angle Similarity.
Hence the triangles are similar.

The new shark tank at the city aquarium is in the shape of a rectangular prism. It is 87 ft long by 36 ft wide by 15 ft deep. deep. To make the tank livable for the sharks, the aquarium workers treat the water using bags of salt. The amount of water a bag of salt can treat is known in cubic yards.
Find the volume of water in the tank in cubic yards. Use the table of conversion facts, as needed.
To make the tank livable for the sharks, a bag of salt must be added for each 1.1 yds3 of water. The aquarium doesn't have any salt on hand and the salt can only be purchased in whole bags. How many bags of salt must be purchased to treat the water?
If each bag of salt costs $4.85, how much must the aquarium pay for salt to treat all the water in the new shark tank?
Answer:
Step-by-step explanation:
Answer:
1. The volume of water in the tank in cubic yards can be calculated by multiplying the length, width, and depth of the tank in feet by the conversion factor of 0.037037 yds3/ft3:
87 ft x 36 ft x 15 ft x 0.037037 yds3/ft3 = 997.78 yds3
2. To treat the water, the aquarium must purchase 998 bags of salt, as 1.1 yds3 of water requires one bag of salt.
3. The aquarium must pay $4,835.30 for the salt to treat the water in the new shark tank. This is calculated by multiplying the number of bags of salt (998) by the cost of one bag of salt ($4.85).

The equation of the line passing through the point (5, - 3) that is parallel to 5x + 7y = 9 will be 5x + 7y - 4 = 0.
What is the equation of a parallel line?Let the equation of the line be ax + by + c = 0. Then the equation of the parallel line that is parallel to the line ax + by + c = 0 is given as ax + by + d = 0.
The equation of the line is given below.
5x + 7y = 9

Out of 50 students in a class 40 percent are girls If 30% of the girls wear apecticals wear spectrals Number of gists. Number of boys Number of girls wearing specticals.
Answer:
Out of 50 students in a class, 40% are girls, meaning there are 50 x 40% = 20 girls in the class.
And the number of boys is 50 - 20 = 30 students.
If 30% of the girls wear spectacles, that means 30/100 x 20 = 6 girls wear spectacles.
And the number of girls not wearing spectacles is 20 - 6 = 14.
So the total number of girls wearing spectacles is 6, and the number of boys is 30, and the number of girls not wearing spectacles is 14.

Given: y = 4x
The number in front of the x is the gradient (slope). This number represents the amount of up or down for a given amount of long.
If the number in front of the x (coefficient) is positive the 'slope' goes up. If the coefficient is negative it means the 'slope' is down.
Now, substitute any value you chose into x, multiply it by 4 and you have your value for y
Let x = 0,
y = 4(0) = 0
So this can be our first point on the graph.
(x₁, y₁) ⇒ (0,0)
Let x = 2
y = 4(2) = 8

The velocity of the ball when it returns to the ground is -8 m/s
What is an equation?An equation is an expression composed of variables and numbers linked together by mathematical operations.
The distance of a ball thrown upward is given by:
h(t) = -2t² + 12t - 10
The ball hits ground when h(t) = 0, hence:
-2t² + 12t - 10 = 0
t = 5 or 1
The velocity (V) of the ball is:
V = dh/dt
V = (d/dt)(-2t² + 12t - 10) = -4t + 12

In this problem we have the coordinates of an endpoint in a line segment and the midpoint of that segment, that is, the point in the line segment that partitions it into two parts of equal length. The formula needed to find the coordinates of the missing endpoint is:
0.5 · P1(x, y) + 0.5 · P2(x, y) = M(x, y)
Where:
P1(x, y), P2(x, y) - Coordinates of the endpoints of the line segment.M(x, y) - Coordinates of the midpoint.If we know that P1(x, y) = (- 6, 4) and M(x, y) = (- 5, 6), then the coordinates of the other endpoint are:
0.5 · P1(x, y) + 0.5 · P2(x, y) = M(x, y)

How to use composition to prove that f(x) and g(x) are inverses?A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
To confirm the inverse relationship using composition.
For valid inverse f(g(x)) must be equal to g(f(x))
f(x) = ∛(x) + 13; g(x) = (x - 13)³:
f(g(x)) = f((x - 13)³)
f(g(x)) = ∛((x - 13)³) + 13
f(g(x)) = x - 13 + 13
f(g(x)) = x
g(f(x)) = g(∛(x) + 13)
g(f(x)) = (∛(x) + 13 - 13)³
g(f(x)) = (∛(x))³
g(f(x)) = x
Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse
f(x) = x³ + 1; g(x) = ∛(x - 1):
f(x) = x³ + 1; g(x) = ∛(x - 1)
f(g(x)) = f(∛(x - 1))
f(g(x)) = (∛(x - 1))³ + 1
f(g(x)) = x - 1 + 1
f(g(x)) = x
g(f(x)) = g(x³ + 1)
g(f(x)) = ∛((x³ + 1) - 1)
g(f(x)) = ∛(x³)
g(f(x)) = x
Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse

Find the perimeter of each polygon
The perimeter of polygon ABC = 67.4
The perimeter of polygon PQRS = 78.8
What is the Perimeter of a Polygon?The perimeter of a polygon is calculated by adding the lengths of all sides of the polygon together.
What is the Two-tangents Theorem?The Two-Tangent Theorem states that if two tangents are drawn to a circle from the same external point, then the tangents are congruent (have the same length).
Perimeter of polygon ABC = AB + BC + AC
AB = 10.5 + (23.2 - 11.2) = 22.5 [based on the Two-Tangent Theorem]
BC = 23.2
AC = 10.5 + 11.2 = 21.7
Perimeter of polygon ABC = 22.5 + 23.2 + 21.7 = 67.4
Perimeter of polygon PQRS = PQ + QR + RS + PS
PQ = 25
PS = 21.8
QR = 13 + 4.6 = 17.6
RS = 4.6 + 9.8 = 14.4

For what values of the variable does each of the following expressions make sense? square root of 1+3a/25
Answer:
the expression "square root of 1+3a/25" makes sense for all values of a that are greater than or equal to -8.333.
Step-by-step explanation:
The square root of a number is only defined for non-negative values of that number. Therefore, for the expression "square root of 1+3a/25" to make sense, the value inside the square root must be non-negative.
1+3a/25 >= 0
This inequality can be rearranged to get the values of a for which the expression makes sense.
3a/25 >= -1
3a >= -25
a >= -25*3/3
a >= -25/3
a >= -8.333
Therefore, the expression "square root of 1+3a/25" makes sense for all values of a that are greater than or equal to -8.333.

The two lines L1 and L2 are parallel
How to identify if the lines are parallelFor two lines to be parallel the slope must be equal, hence we calculate the slope of the two lines
The slope, m of the linear function L1 is calculated using the points (–2, 9) and (1, 3)
m = (y₀ - y₁) / (x₀ - x₁)
m = (9 - 3) / (-2 - 1)
m = (6) / (-3)
m = -2
The slope, m of the linear function L2 is calculated using the points (–4, 10) and (3, –4)
m = (y₀ - y₁) / (x₀ - x₁)
m = (10 + 4) / (-4 - 3)
