Answer:

ED: 6.5 cm BE = 14.4 cm

Step-by-step explanation:

Add 20 and 5 to get side AC.

25/20 gives us the scale factor to go from 25 triangle ABE to triangle ACD.

Multiply 26 by the SF to get AD.

Subtract length of AD by AE to get ED. You should get 6.5 cm (don't forget units!!!!)

To go from triangle ACD to triangle ABE, we can do 20/25 to get the scale factor.

Using that number, multiply it with 18 to get BE.

The answer should be 14.4 cm.

This is possible because the two triangles ACD and ABE are similar via the angle angle angle similarity theorem depicted in my screenshot.

a jar contains 36 marbles. it has 20 red, 12 black, and 4 green marbles. two marbles are drawn; the first is not returned before
Igoryamba
P(red) first drawn:
20/36=5/9
P(red) second drawn:
19/35

95/315 or 19/63. As a result, the probability that both marbles are red is 19/63. Hope it help!

A bag contains pieces of paper with the following numbers on them: 1, 2, 3, 5, 7, 9, 10, 11.
liq [111]

Answer:

See below in bold.

Step-by-step explanation:

There are 2 even and 6 odd numbers in the list.

A.

Prob(Picking an odd number) = number of odd numbers / total of numbers

= 6/8 = 0.75.

Prob(Picking a 10) = 1/8 = 0.125.

Answer = 0.75 * 0.125 = 0.09375

= 0.094 to 3 dec. places.

B.

Prob( Picking and even) = 2/8 = 1/4.

Prob( Picking another even without replacement) = 1/7.

Answer = 1/4 * 1/7 = 1/28

= 0.036 to 3 dec. places.

C.

There are 5 numbers greater than 4.

Prob(Picking a number > 4) =  5/8.

Prob( Picking a 1 without replacement) = 1/7.

Answer = 5/8 * 1/7

= 5/56

= 0.089 to 3 dec. places.

Carlos can print a document on apricot printer which the speed is 8 in 4.5 minutes how long would it take him to print the same
kupik [55]
The apricot printer has a speed of 8.
The surefire printer has a speed of 12.

The surefire is faster than the apricot printer, so it wll take less time to print a document.
The apricot printer takes 4.5 minutes.
Therefore by proportion, the surefire printer takes
(8/12)*4.5 = 3 minutes.

Answer: 3 minutes
