Answer:
60 Hundreds, 30 Fifty's, 2 ones
There are 20 boys in the class. The ratio is 4:3 so that means 4 out of 7 are boys and 3 out of 7 are girls. Divide 35 by 7 and you get 5. 5 times 4 is 20. 5 times 3 is 15. add them together and you have 35 students in total. So 20 students are boys and 15 students are girls.

Answer:
3.5 cm
Step-by-step explanation:
Given the question:
A circular arc has measure 8 cm and is intercepted by a central angle of 2.3 radians. Find the radius of the circle. Do not round any intermediate computations, and round your answer to the nearest tenth.
Central angle in radian (θ) = 2.3 radian
Length of arc (s) = 8cm
Recall:
Length of arc (s) = radius (r) × central angle (θ)
8cm = radius × 2.3 rad
radius = 8 / 2.3
Radius = 3.478 cm
Radius = 3.5 cm
