Answer:
Step-by-step explanation was 34
Let the smaller number be x
x+x+7=63
2x+7=63
2x=56
x=28
28+7=35
The two numbers are 28 and 35
Answer:
number of students in a van=12
number of students in a bus=52
Step-by-step explanation:
let number of students in a van=x
number of students in a bus=y
1x+6y=324 ...(1)
9x+3y=264 ...(2)
multiply (2) by 2
18x+6y=528 ...(3)
(3)-(1) gives
17x=204
x=204/17=12
put in (1)
12+6y=324
6y=324-12=312
y=312/6=52
Answer: 523.8 m^3
Step-by-Step Solution:
Radius (r) = 5 m
Volume of a Sphere (V) = 4/3 πr^3
Therefore,
= 4/3 πr^3
= 4/3 * 22/7 * (5)^3
= 4/3 * 22/7 * 125
= 88/21 * 125
= 11000/21
=> 523.8
Volume of the Sphere (V) = 523.8 m^3
