RU and JM are diagonals. Given ST= 6, KL = 10, and RU= 12, find JM

AfilCa [17]

Your question is incomplete. The complete question is attached down

Answer:

JM = 20 units

Step-by-step explanation:

∵ Hexagon RSTUVW is similar to hexagon JKLMNP

∴ The corresponding sides and diagonals have a constant ratio

∴ $\frac{RS}{JK}=\frac{ST}{KL}=\frac{TU}{LM}=\frac{UV}{MN}=\frac{VW}{NP}=\frac{RW}{JP}=\frac{RU}{JM}$

∵ ST = 6 units

∵ KL = 10

∴ $\frac{ST}{KL}=\frac{6}{10}$

- Simplify it by dividing up and down by 2

∴ $\frac{ST}{KL}=\frac{3}{5}$

∵ $\frac{ST}{KL}=\frac{UR}{JM}$

∵ RU = 12 units

∴ $\frac{3}{5}=\frac{12}{JM}$

- By using cross multiplication

∴ JM × 3 = 5 × 12

∴ 3 JM = 60

- Divide both sides by 3

∴ JM = 20 units

f the probability of being hospitalized during a year is 0.25 , find the probability that no one in a family of five will be ho

Kaylis [27]

Answer:

The probability that no one in a family of five will be hospitalized in a year is 0,2373

Step-by-step explanation:

Let p denote the probability of being hospitalized during a year,

Then p=0.25

And p' the probability of not being hospitalized during a year is 1-p

Thus p' = 1-p = 1-0.25 = 0.75

The probability that no one in a family of five will be hospitalized in a year is equal to $p'^{5}$ . That is

$p'^{5}$ = $0.75^{5}$ ≈ 0,2373

Point b lies on the segment ac . Find the length of the segment ac, if ab=7.8 cm, bc=25mm. How many different solutions can this

mixas84 [53]

Given that B lies on segment AC and AB=7.8cm , BC = 25mm

Let us convert AB to mm by multiplying with 10 that is AB = 78mm

There are totally 3 possible ways for B lying on segment AC.

Solution 1:- B lies in between A and C,

Then AC = AB+BC

=78+25 = 103 mm

Solution 2:- B lies to the right of C like ACB.

Then AB = AC+CB

78 = AC+25

AC = 78-25 = 53mm

Solution 3:- B lies to the left of A like BAC.

Then BC = BA+AC

25 = 78+AC

Since AC cannot be negative, this way is not possible.

Hence there are only 2 solutions possible.

If we are given that B lies on line joining A and C, then definitely B should lie between A and C. That means nothing but solution 1. So only one solution is possible in this case.
