Answer:
105
Step-by-step explanation:
500 goes into 100, 5 times
21 times 5 is 105
So 21/100 is equal to 105/500
Or you can do
500*0.21=105
S= Sydney
devaughn= s-13
so s+s-13=75
2s-13=75
now I think you can solve the rest.
Probability that gear 1 will fail = 5/100 (upto 10 years)
and 8/100 (after 10 years)
Probability that both will fail = 5/100 * 8/100
= 40/10000
= 0.4 %
Answer:
1200 seconds per 20 minute study session
Step-by-step explanation:
20 min x 60 sec = 1200 seconds
1) <u>Find the length of the diagonals of the greater rhombus</u>
NJ=9 units
XY=6 units
Find the the ratio
NJ/XY=9/6-------> 3/2
2) <u>Find the length of the diagonals of the smaller rhombus</u>
HS=6 units
ZC=4 units
Find the the ratio
HS/ZC=6/4-------> 3/2
so
NJ/XY=HS/ZC--------> the rhombus are similar
the scale factor is equal to ------> 3/2=1.5
measure greater rhombus =scale factor*measure smaller rhombus
measure greater rhombus =1.5*measure smaller rhombus
measure smaller rhombus=(measure greater rhombus/1.5)
therefore
<u>the answer is</u>
Yes , they are a scaled copies and the scale factor is equal to 1.5
