To begin to solve this problem, we need to figure out by what number the sides are similar. That means what do we have to multiply the sides of one triangle to get the sides of the other triangle.

If the longest side of a similar triangle measures 39 centimeters, we can divide 39 by 65 (the longest side of the triangle we know) to figure out what we have to multiply each of the sides of the triangle. 39 / 65 is 0.6, so the triangles are similar by a factor of 0.6.

Since the question asks us for the length of the shortest side, we need to multiply the length of the shortest side of the triangle that we know (25) by 0.6. 25 * 0.6 is 15, so the length of the shortest side of this triangle is 15 cm.

A similar triangle means it is of a diferent size, but the sides or angles are proportionaly the same.

Use the rule of 3 on each number, to find the equivalent sides:

65 - 39

60 - x

(60 * 39) / 65

2340 / 65

36cm

60 - 36

25 - x

(25*36) / 60

900 / 60

15cm

Original triangle: 65, 60, 25

Similar triangle: 39, 36, 15

Answer:

$\boxed{\bf~The~smallest~side~of~the~trianlge~measures~15cm.}$

Hope it helped,

Happy homework/ study/ exam!

A manager records the number of hours, X, each employee works on his or her shift and develops the probability distribution belo

Reika [66]

Answer:

c. 2

Step-by-step explanation:

Given : X = No. of hours worked

No. of people work for the manager = 50

X = 3, 4 , 5 , 6 , 7, 8

P(X) = 0.1 , ? , 0.14 , 0.3 , 0.36 , 0.06

To Find : No. of people work for four hours

Solution : First understand the fact that sum of all probabilities is equal to 1

So, sum of all values of P(X) = 1

⇒ $0.1+?+0.14+0.3+0.36+0.06 = 1$

⇒ $0.96+? = 1$

⇒ $?= 1-0.96$

⇒ $? = 0.04$

So, the probability of no. of people worked for 4 hours is 0.04.

⇒P(4)=0.04

Thus , To calculate no. of people work for four hours :

$0.04\times 50$

⇒ 2 no. of people work for four hours per shift .

there are 650, of that 650 48% do go, 44% doesn't go, how many students are not sure they will attend?

Katarina [22]

44% + 48% = 92%
48% go, 44% dont go...so thats 92% that either go or dont go....leaving u with 8% unsure
0.08(650) = 52 are not sure they will attend

So the question on the pic

gtnhenbr [62]

Explanation + answers

Because there are lengths going from 0 to 1, the lines must mean either decimals or fractions (we'll use fractions for this.)

1. There are twelve lines from 0 and 1, which we can use as the denominator for our fraction. This means the length of each line is 1/12.

2. In order to find where K's point is at, we simply need to count until we get to it. After counting, I see that K is on point 8/12, which we can simplify to get a smaller number. If we simplify once, we get 4/6, which we can again simplify to get 2/3. This gives us the answer K is on point 8/12 or 2/3.

Jacob went camping with his family. At 7:15 A.M., Jacob set out to go fishing. It took 1 hour and 45 minutes to hike to the lake

GREYUIT [131]

Answer:

7:15 A.M.
1 hour and 45 min = 105 min
3 hour 45 min= 225 min
1 hour and 15 min = 105 min
105(2)+ 225= 435 min= 7 hours and 25 min.
Add that to the original total you get 14:40 P.M
