The sum of 3 consecutive odd natural nos. can be represented by n + ( n+2 ) + (n + 4 ).
What are consecutive nos. ?Consecutive nos. are every no. after each other.
According to the given question we have to represent the sum of 3 consecutive odd natural nos.
We know that consecutive odd natural nos. come after every two digits.
∴ Assuming the first odd natural no. to be n.
So, Next odd natural no. will be (n + 2) and the third consecutive odd natural no. will be (n + 2) + 2 which is = (n + 4).
∴ The sum of 3 consecutive natural numbers can be represented by
n + (n + 2) + (n+4).

The radius of a sphere is increasing at a rate of 5 mm/s. How fast is the volume increasing when the diameter is 100 mm?
Answers
Answer:
157,143 mm/s
Step-by-step explanation:
Formula for the volume of a sphere is;
V = 4/3 * pi * r^3
dv/dr = 4 pi r^2
dv/dt = dv/dr * dr/dt
dr/dt = 5 mm/s
dr/dt = 4 * pi * r^2
r = d/2 = 100/2 = 50 mm
dr/dt = 4 * 22/7 * 50^2 = 220,000/7
dv/dr = 220,000/7 * 5 = 157,142.8571428571

what is 168 divided by 12 but using estimation
Answers
Answer:
14
Step-by-step explanation:
The division of the number 198 by 12 is approximately 17.
A mathematical process known as division can be used to divide a sum of money into equal parts or to calculate how many times one number can be found inside another.
A quotient is produced as a result of dividing a dividend (the number being divided) by a divisor (the number by which the dividend is divided).
To estimate the division of 168 by 12, we can use rounding to simplify the calculation.
Round the numbers to a more manageable value. In this case, we can round 168 to 170 and 12 to 10.
Divide the rounded numbers. 170 divided by 10 is equal to 17.
Therefore, an estimated answer to the division of 168 by 12 is approximately 17.

The radius of a spherical ball is increasing at a rate of 2 cm/min. At exactly what rate (in cm2/min) is the surface area of the ball increasing when the radius is 9 cm?
Answers
Answer:
9th min?
Step-by-step explanation:
lol sorry im set 4 maths
144π cm²/min is the surface area of the ball increasing when the radius is 9 cm.
What is Surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given,
Radius of a spherical ball is increasing at a rate of 2 cm/min.
We need to find exactly what rate (in cm2/min) is the surface area of the ball increasing when the radius is 9 cm
S = surface area at time t, and r = radius at time t
r=9cm
dr/dt = 2 cm/min
S = 4πr²
Differentiate with respect to t
ds/dt=2.4πrdr/dt
=8πr(2)
=16πr
=16π(9cm)
=144π cm²/min
Hence 144π cm²/min is the surface area of the ball increasing when the radius is 9 cm.
