Answer:
radius= 19
Step-by-step explanation:
diameter(d) = 38cm
radius (r) = d/2
= 38/2
= 19cm
Answer:
B
Step-by-step explanation: The answer is B because the dilation is showing that the triangle is getting bigger therefore the answer is going to be 1 or more
Triangle from angles XBR=130 cm
Triangle from angles YNJ=65cm
Answer:
The sprinter
Step-by-step explanation:
Change cyclist to same units as sprinter (m/s)
20 km = 20x1000 m = 20000 m
1 hour = 60 minutes = 60 x 60 = 3600 sec
So 20 km/hr = 20,000 m / 3600 sec = 5.6 m/s
The sprinter is faster as he travels at 8 m/s.
(Similarly if you change the sprinter's speed into km/hr
you should get 28.8 km/hr)
let x be the first number,
so, the next two are (x+ 1) and (x+2)
x + 2(x +1) = 62 - 3(x + 2)
x + 2x + 2 = 62 -3x - 6
3x + 2 = 62 - 3x - 6
3x + 3x = 62 - 6 - 2
6x = 54
x = 9
so, three consecutive integers are
9, 10, 11
Hope this helps!
