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.
Here we are given the equation 3x+k =c
Here in order to solve for x , first let us bring k to the right side.
k is in addition on the left , so when we bring it to the right it gets subtracted
now we have to isolate x on the left side , 3 is in multiplication with x , so when we bring it to the right side we divide by 3
Answer: 
Answer:
A demand curve or a supply curve is a relationship between two, and only two, variables: quantity on the horizontal axis and price on the vertical axis.
Step-by-step explanation:
Answer:
x=5
Step-by-step explanation:
x=5
A bag of potatoes weighs 9.42 pounds on a weighing scale.
In order to find least significant digit we have these rules,
1. The leftmost non zero digit is the most significant digit.
2. If there is no decimal point, the rightmost non zero digit is the least significant digit.
3. If there is a decimal point, the rightmost digits is the least significant digit even if it is a zero.
4. All digits between the least and most are also significant digits.
In our case rule number 3 is to be applied.
Our number is 9.42, the rightmost digits that is 2 is the least significant digits.
