Answer:
-3, 9
Step-by-step explanation:
The constant is 4.
Subtract the amount you have from the amount you need:
2 cups - 1 3/8 cups
Subtract the whole cup first:
2 cups -1 cup = 1 cup
8/8 = 1
Rewrite 1 as 8/8 then subtract the 3/8 you have:
8/8 - 3/8 = 5/8
You need 5/8 cup more
3x-5x+3 Answer:
Step-by-step explanation:
Answer:
Given:
The radius of a wheel =r=35 cm=0.35 cm.
The speed it must keep =s=66 km/h=
60
66×1000
m/min=1100 m/min
To find out:
The number of revolution =n, it makes per minute to maintain that speed.
Solution:
The circumference =C of the wheel =2πr=2×
7
22
×0.35 m=2.2 m=C
The distance the wheel covers in 1 min=d=1100 m.
Now the distance =d covered by a wheel in one revolution = the circumference of the wheel.
∴ Here the number of revolution =n=
C
d
=
2.2
1100
=500.
