Sorry a bit messy, with a ratio of 2:5:1, that means 5 would be the longest and your longest piece is 125, diving 125 by 5 gets you 25 cm, this is also your shortest piece since 1x25=25
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
we know that
<em>In the right triangle ABC</em>
-----> by a 45°-90°-45° triangle
so


substitute the values

<em>In the right triangle BCD</em>

substitute the values

Answer:
The answer is "False."
Explanation:
An area is considered the amount of space that an object occupies. A filled-area subjects the object to be made up of lines. These lines connect with each other to form an "edge."
The connection of the lines in order to define the object's shape or area are considered "snap points." Remember that "polygons" are made of line segments, where their endpoints meet with each other in order to define its closed shaped. <u>Thus, it needs to conform to "snap points."</u>
This explains the answer.
Answer:
9: 1/36 chance of getting the same number on both dice
10: a) 5 b) 4/25
Explanation:
9: a die has 6 sides with each number. So the chance of getting a number on a dice once is 1/6. The second dice is the same with 1/6 chance. But to have them both be the same number means you have to multiply the probability. (1/6)/(1/6)=1/36
10:
a) 1/4 of the discs are blue, meaning you have multiply 1/4 by 20 which equals 5
b) the probability of getting a red is 12/20. So the probability of not getting red is 8/20. But both simultaneously, would mean for multiplying them. 8/20 •8/20=64/400 Then simplified to 4/50.
*im not super sure about 10 b. Sorry :/
Step-by-step explanation:
7 - 3b-2(0 + 3 - 2b)
To simplify the expression in the box, Fatua used
these steps:
Step 1:7 - 3b-2(3 - 3b)
Step 2:7 - 3-6-36-
Step 3: -13 - 66
Did Fatua calculate correctly? if nnot, in what step
did she make her FIRST mistake?
