The answer is 40%. Count how many right triangles there are, there are 20 right triangles. Count how many right triangles are shaded in, there are 8 right triangles that are shaded in. 8/20=0.4 or 40%
Answer: Clanssa’s team collects m magazines for the recycling drive. JoAnn’s team collects 3 times as many magazines as Clarissa’s team. JoAnn’s team collects a total of 654 magazines.
Answer:
See below.
Step-by-step explanation:
Corresponding angles and sides are the pieces that match between two different figures.
5. For these two triangles:
Side AB corresponds to Side DE
Side BC corresponds to Side EF
Side CA corresponds to Side FD
Angle A corresponds to Angle D
Angle B corresponds to Angle E
Angle C corresponds to Angle F
6. For these two triangles:
Side LM corresponds to Side RS
Side MO corresponds to Side ST
Side OL corresponds to Side TR
Angle L corresponds to Angle R
Angle M corresponds to Angle S
Angle O corresponds to Angle T
The stiffness of one short spring is 13500 N/m
<em><u>Solution:</u></em>
We are given a chain with number of spring N = 30 and linked end to end ( in series) and stiffness of this chain is 450 N/m
We have to find the stiffness of one short spring
The springs are identical, which means they have same stiffness
<em><u>The stiffness of one spring in series is given as:</u></em>
Where,
N is the number of springs
is the stiffness of one spring
is the stiffness of this chain
Substituting,
Therefore,
Thus the stiffness of one short spring is 13500 N/m
