Hello,
x=18
Radius=√(7²+9²)=√130
(2*√130)²=x²+14²==>x²=√324=18
Answer:
$960
Step-by-step explanation:
Given data
Principal=$800
rate= 4%
time= 5years
Applying the compound interest expression we have]
A=P(1+rt)
substitute
A=800(1+0.04*5)
A=800(1+0.2)
A=800*1.2
A=$960
(a)
pavan saves = x
his 1st brother saves = x + 4
2nd brother saves = x +4
all together they save = x + x +4 + x + 4
= 3x+8
so
3x + 8 = 26
(b)
3x + 8 = 26
subtract 8 from.both side
3x + 8 - 8 = 26 - 8
3x = 18
divide by 3 both side
3x/3 = 18/3
x = 6
so pavan saves $ 6 each month

Answer:
350m
Step-by-step explanation:
- capacity= volume/1000
- but we know that volume of cylinder is πr²h so substitute it I'm the volume space
- then substitute for π as 22/7, h as 1.4 , and also capacity as 539
- 539= ((22/7)×r²×1.4)/1000
- when you simplify you get r as 350m
