I am so so sorry, i know what it feels like to lose a friend. the advice i was given was to be nice to them even if they are mean to you and try to get your mind off it. i can suggest listening to music and watching minecraft twitch streamers like tommyinnit dreamwastaken and georgenotfound seriously, they help anxiety and boredom. try to stay calm when in court and if you look it up on the internet, there is a military method to sleep that makes me settle down to sleep. then you can take deep breaths and maybe listen to white noise or music. so so sorry this is happening to you :((
Answer:
10 : 3
Step-by-step explanation:
Convert one of the measurements so that it is in the same form as the other. (Easiest to convert m to cms so we are not working with decimals)
2.5 m = 2.5 x 100 = 250 cm (since there are 100 cm in a meter)
Therefore, as a ratio:
250 : 75
We can divide both by 5:
50 : 15
We can further divide by 5:
10 : 3
(no further simplifying)
So 2.5 m to 75cm as a ratio is 10 : 3
Answer:
No Triangles: A, C
One Triangle: D, F
Many Triangles: B, E
Step-by-step explanation:
Hope this helps!
This is the concept of algebra, for us to calculate the area of the triangle we need the value of x. Therefore, we shall obtain this from the perimeter.
P=6x+4x+3x=18
13x=18
x=18/13
x=1.385
The length of the altitudes will be:
6x=6×1.385=8.31
4x=4×1.385=5.54
3x=3×1.385=4.155
the area will be given by Heron's formual:
Area=√[p(p-a)(p-b)(p-c)]
p=(a+b+2)/2
=(8.31+5.54+4.155)/2
=9.0025
therefore:
A=√[9.00(9-8.31)(9-5.54)(9-4.155)
A=104.64 sq. units
Answer:
- perimeter: 36 units
- area: 54 square units
Step-by-step explanation:
The perimeter is multiplied by the scale factor:
image perimeter = 3 × original perimeter = 3×12 = 36 units
The area is multiplied by the square of the scale factor:
image area = 3² × original area = 9×6 = 54 square units
