The sum of A² and B² (45.53) is not equal to C² (37.21). Therefore, the blocks cannot form a right-angled triangle, and the tower will not be stable.
To determine whether the tower will be stable, we need to check if the lengths of the blocks satisfy the conditions for forming a right-angled triangle. According to the Pythagorean theorem, in a right-angled triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
Let's label the blocks:
Blue block: Side A = 4.3 inches
Orange block: Side B = 5.2 inches
Red block: Side C = 6.1 inches
To form a stable tower, we need to check if the sum of the squares of the two shorter sides is equal to the square of the longest side.
Calculating the squares:
A² = 4.3² ≈ 18.49
B² = 5.2² ≈ 27.04
C² = 6.1² ≈ 37.21
Now, we need to find the longest side. Let's compare the squares:
C² (37.21) is the largest.
According to the Pythagorean theorem, for a right-angled triangle, the sum of the squares of the two shorter sides must be equal to the square of the longest side. In this case, the sum of the squares of A² and B² should be equal to C².
A² + B² ≈ 18.49 + 27.04 ≈ 45.53
However, the sum of A² and B² (45.53) is not equal to C² (37.21). Therefore, the blocks cannot form a right-angled triangle, and the tower will not be stable.

What is the area of a square with a perimeter of 44 mm?
Answer:
The area of the square is 121mm
Step-by-step explanation:
To solve this we need two basic formulas:
P = 4s
A = [tex]s^{2}[/tex]
P = perimeter
s = the length of the side
Since the shape is a square all the sides are the same length. To get the value of 's' we need to isolate:
P = 4s
44 = 4s
44 / 4 = 4s / 4
11 = s
Now plug in the answer for 's' to get the area:
A = [tex]s^{2}[/tex]
A = [tex]11^{2}[/tex]
A = 121

As always, the first step is to read and understand the question. You are asked to find the smallest number in the set {M₁, M₂, M₃}. Each of these values is defined to be the largest number in the corresponding sets S₁, S₂, S₃.
Set MThe numbers in each set are ordered smallest to largest, so the largest number in each set is the one on the right.
The largest number in S₁ is 8, so M₁ = 8.
The largest number in S₂ is 6, so M₂ = 6.
The largest number in S₃ is 0, so M₃ = 0.
This means the set M is ...
M = {M₁, M₂, M₃} = {8, 6, 0}
The question asks for the smallest number in set M. Clearly, it is 0.
The smallest number in the set is 0.

Kelly is 5'4" tall. She measured her shadow one morning to be 8'7". She then measured the shadow of her house. The house shadow was 42'3". How tall is the
actual house? (inches rounded to the hundredths.)
The height of the actual house is 26'.26" .
How to find the height of the house using ratio?A ratio indicates how many times one number contains another.
Therefore, the heights will form a similar length. Therefore, the corresponding length have the same ratios.
Therefore,
height of Kelly / x = height of Kelly shadows / height of house shadow
Hence,
where
x = actual height of the house
5.4 / x = 8.7 / 42.3
cross multiply
42.3 × 5.4 = 8.7x
Therefore,
228.42 = 8.7x
divide both sides by 8.7
228.42 / 8.7 = 8.7x / 8.7

They are parallel because they have the same slope of 2.
How to determine the true statements about the segments?The segments are given as;
AB => 6x - 3y = 9
CD => 4x - 2y = 8
We start by making y the subject of both equations
AB => 6x - 3y = 9
-3y = -6x + 9
Divide through by -3
y = 2x - 3
CD => 4x - 2y = 8
-2y = -4x + 8
Divide through by -2
