What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.
A) 7.2
B) 6.0
C) 2.8
D) 6.3
Answers
Answer:
We conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.
Step-by-step explanation:
Given
L(3,4)M(1,-2)Determining the length of LM
(x₁, y₁) = (3, 4) (x₂, y₂) = (1, -2)The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)
[tex]=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}[/tex]
[tex]=\sqrt{2^2+6^2}[/tex]
[tex]=\sqrt{4+36}[/tex]
[tex]=\sqrt{40}[/tex]
[tex]=\sqrt{4\times 10}[/tex]
[tex]=\sqrt{2^2\times \:10}[/tex]
[tex]=2\sqrt{10}[/tex]
[tex]=6.3[/tex]
Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:
[tex]d = 6.3[/tex]
Hence, option D is correct.

The ratio of number of male and female teachers in a school is 3:4. Find the number of male teachers if there are 16 female teachers
Answers
Answer:
12 male teachers
Step-by-step explanation:
If the ratio is 3:4, and the number of female teachers is 16, then the number of male teachers must be 12. This can be confirmed by multiplying both 3 and 4 by 4, or 12/16 = 3/4.
Answer:
12 male teachers.
Step-by-step explanation:
if there is 16 females and the ratio is 3:4 it would be 12 due to 4 times 4 being 16. Meaning that i would do 3 times 4 which would result in having 12 male teachers.

Given that a varied inversely as b, and b varies directly as the square of c, and a=1 when c=3 find the value of a when c=1/3
Please I need solvings for this thanks
Answers
Answer:
81
Step-by-step explanation:
When two variables have direct variation, as one variable increases the other variable increases or as one variable decrease, the other decrease. While for an inverse variation, as one variable increase, the other variable decrease or as one variable decrease, the other variable increase.
Given that a ∝ 1/b. Also b ∝ c².
Hence if k is the constant of proportionality, we have:
a ∝ 1 / c²
a = k / c²
When a = 1, c = 3, hence:
1 = k / 3²
k = 1 * 3²
k = 9
Therefore:
a = 9 / c²
When c = 1/3
a = 9 / (1/3)²
a = 9 / (1² / 3²)
a = 9 / (1 / 9)
a = 9 * 9
a = 81

A contestant in a weight loss competition wants to lose an average of at least 8 pounds
per month during a 5-month period. In the first 4 months they have lost the following
weight: 12 lbs, 9 lbs, 5 lbs, 8 lbs. How many pounds must the contestant lose in the fifth
month to meet the goal?
Answers
Answer:
In the fifth month the contestant must lose 6 pounds of weight.
Step-by-step explanation:
Given that the contestant wants to lose an average of 8 pounds of weight per month for 5 months, taking into account that in the first 4 months of the contest he lost 12, 9, 5 and 8 pounds respectively, to determine how much weight he should lose in the fifth month the following calculation must be performed:
8 x 5 = 40 (pounds to lose)
12 + 9 + 5 + 8 = 34 (pounds lost)
40 - 34 = 6
Therefore, in the fifth month the contestant must lose 6 pounds of weight.
