In this fulcrum, the weights are perfectly balanced. How far must the fulcrum be located from the 40 lb. weight if the bar is 11 feet long? x (to the nearest tenth) =
Answers
we know that
if the weights are perfectly balanced
40*(x)=50*(11-x)
40x=550-50x------------> 50x+40x=550--------------> x=6.11
x=6.1 ft
the answer is 6.1 ft
Answer:
[tex]x=6.11 feet[/tex]
Step-by-step explanation:
Given that in a fulcrum weights are perfectly balanced.
One side 40 lb weight is there and another side 50 lb weight is given
Let x be the length of 40 lb weight from fulcrum. Then 50 lbs is at a distance of 11-x.
Then we have since weights are perfectly balanced
[tex]40x = 50(11-x)\\90x=550\\x=6.111[/tex]
Thus we get [tex]x=6.11[/tex]feet

Which postulate or theorem can be used to prove that △JKL is similar to △MKN?
A. SSS Similarity Theorem
B. ASA Similarity Theorem
C. AA Similarity Postulate
D. SAS Similarity Theorem
Answers
Answer:
The correct option is D.
Step-by-step explanation:
In triangle △JKL,
[tex]\frac{JK}{KL}=\frac{30}{50}=\frac{3}{5}[/tex]
In triangle △MKN,
[tex]\frac{MK}{KN}=\frac{15}{25}=\frac{3}{5}[/tex]
In triangle △JKL and △MKN
[tex]\frac{JK}{KL}=\frac{MK}{KN}[/tex]
[tex]\angle JKL=\angle MKN[/tex] (Vertically opposite angles)
Since two sides are proportional and an inclined angle is congruent, so by SAS theorem of similarity we get
[tex]\triangle JKL=\triangle MKN[/tex]
Therefore option D is correct.

A rectangle has a a perimeter of 72 ft. The length and width are scaled by a factor 3.5.
What is the perimeter of the resulting rectangle?
Enter your answer in the box.
Answers
P=2(L+w)
P=2L+2w
Here Perimeter, p= 72 ft
And scale factor of length and width=3.5 which means rectangle is enlarged.
So perimeter of rectangle= 3.5 x 72
P=252ft
Answer: 252 ft
We also know that the perimeter P of the rectangle is defined as:
P=2L+2W.
So P is directly proportional to L+W. This means that if L or W were to get bigger, P will get bigger, and if L or W were to get smaller P will get smaller.
The question also states that both L and W are scaled by the same factor of 3.5 .
This means the sum of the dimensions L+W is scaled by 3.5
It also means that the perimeter is upscaled by 3.5 as it is proportional to L+W.
P = 72 ft × 3.5 = 252 ft.
252 ft is the answer.

D)One cm represented 12 in. in the first scale, but now 1 cm represents 11 in. in the second scale.
Answers
Answer:
The correct answer is option A,
One cm represented 11 in. in the first scale, but now 1 cm represents 12 in. in the second scale
Step-by-step explanation:
The earlier planned length was [tex]44 in\\[/tex]
So the scale of the map was
[tex]\frac{44}{4} \\= 11\\1 cm = 11 in\\[/tex]
The second planned length was [tex]48 in\\[/tex]
So the second scale of the map was
[tex]\frac{48}{4} \\= 12\\1 cm = 12 in\\[/tex]
Thus, option A is correct.

The lowest common denominator for the fractions 8/64 and 8/32 is ?
Answers
Final answer:
The lowest common denominator for the fractions 8/64 and 8/32 is 32. This is found by identifying 32 as the least common multiple of the denominators 64 and 32, allowing both fractions to be expressed with the same denominator.
Explanation:
Finding the Lowest Common Denominator
To find the lowest common denominator (LCD) for the fractions 8/64 and 8/32, you must identify the smallest number that both denominators can divide into without leaving a remainder. Both 64 and 32 can be divided by 32, so the LCD for these fractions is 32. It's important to understand that finding an LCD involves looking for the least common multiple (LCM) of the denominators. In this case, since 32 is a multiple of 64 (32x2=64), it serves as the LCM of 32 and 64, and consequently, the LCD of the fractions.
To further clarify, each fraction can be expressed with a denominator of 32. For 8/64, when we divide both the numerator and denominator by 8, we get 1/8. This fraction can then be converted to have a denominator of 32 through multiplication by 4 (1/8 * 4/4 = 4/32). Similarly, the fraction 8/32 is already expressed with the desired denominator.
By finding the LCD, it is easier to perform addition, subtraction, or comparison of fractions, as they will share the same denominator.
The lowest common denominator for the fractions [tex]\( \frac{8}{64} \) and \( \frac{8}{32} \) is \( \boxed{64} \).[/tex]
To find the lowest common denominator (LCD) for the fractions [tex]\( \frac{8}{64} \) and \( \frac{8}{32} \)[/tex], we need to determine the least common multiple (LCM) of the denominators 64 and 32.
Step 1: Find the prime factorization of each denominator:
[tex]- \( 64 = 2^6 \)[/tex]
[tex]- \( 32 = 2^5 \)[/tex]
Step 2: Determine the LCM by taking the highest power of each prime that appears in any factorization:
[tex]\[ \text{LCM} = 2^{\max(6, 5)} = 2^6 = 64 \][/tex]
Therefore, the LCD of the fractions [tex]\( \frac{8}{64} \) and \( \frac{8}{32} \) is \( 64 \).[/tex]
Step 3: Verify that ( 64 ) is indeed the LCD:
[tex]- \( \frac{8}{64} = \frac{1}{8} \)[/tex]
[tex]- \( \frac{8}{32} = \frac{1}{4} \)[/tex]
Both fractions can be rewritten with a denominator of ( 64 ):
[tex]- \( \frac{1}{8} = \frac{8}{64} \)[/tex]
[tex]- \( \frac{1}{4} = \frac{16}{64} \)[/tex]
Therefore, ( 64 ) is the lowest common denominator for[tex]\( \frac{8}{64} \) and \( \frac{8}{32} \).[/tex]
Thus, the lowest common denominator for the fractions [tex]\( \frac{8}{64} \) and \( \frac{8}{32} \) is \( \boxed{64} \).[/tex]

In the United States, the mean average height of adult women is approximately 65.5 inches, with a standard deviation of 2.5 inches. If height is normally distributed,what percent of the women in this country are between 63 and 70.5 inches tall?
Answers
The z-score for x = 63 is: z = (63 - 65.5) / 2.5 = -1
The z-score for x = 70.5 is: z = (70.5 - 65.5) / 2.5 = 2
Therefore we need the probability that -1 < z < 2. This is equivalent to the probability that z < -1, subtracted from the probability that z < 2. From z-tables, we find that this is equal to 0.9772 - 0.1587 = 0.8185. This means that 81.85% of women's heights fall within this range.
