Answer:
x = 3
y = 5
Step-by-step explanation:
Using theorem of similar triangles, we have,
(6 + x)/6 = (7 + 3.5)/7
(6 + x)/6 = 10.5/7
Cross multiply
7(6 + x) = 10.5(6)
42 + 7x = 63
7x = 63 - 42
7x = 21
x = 21/7
x = 3
Thus:
7.5/y = (7 + 3.5)/7
7.5/y = 10.5/7
Cross multiply
7.5*7 = 10.5*y
52.5 = 10.5*y
Divide both sides by 10.5
52.5/10.5 = y
y = 5

Step-by-step explanation:
Circumfrence= 2 x pi x Radius
2 x 3.142 x 7.5 =47.13
Answer:
you should put 6 because 3/8 X 6 =18/8=2 2/6
Step-by-step explanation:
Answer:
4^4= 4^-1(3r+2)
4^4= 4^(-3r-2)
-3r-2 = 4
-3r= 6
r= -2

Step-by-step explanation:
1. If Martin climbs 3 1/3 meters in the first one 1/6 hour, then he climbs
meters per hour. Then, option A is correct and options C and E are false.
2. If Alexia climbs 17 1/2 in the first 5/6 hour, then she climbs
meters per hour and it takes Alexia of an hour to climb 1 meter. Then options B and D are correct and option F is false.
Answer: correct options are A, B and D.
