111 1/10+ 496 1/10 is approximately

Mnenie [13.5K]

111+496= 607
1/10 + 1/10 = 2/10
607 + 2/10 = 607 and 2/10

But if youre just doing an approximate answer then...

111 = 110
496 = 500
So it would be 610

You can make 2/10 to 1/5 but that wouldnt be approx.

Your answer should be 610 and 2/10

A publishing industry report predicts that magazine subscriptions will drop

Mrrafil [7]

Answer:

24,393 subscribers

Step-by-step explanation:

This is <u>exponential decay</u> problem. The formula for exponential decay is:

$F=P(1-r)^t$

Where

F is the future value (what we are looking for, in 7 years)

P is the present amount (that is 51,000)

r is the rate of decrease per year (r = 10% = 10/100 = 0.1)

t is the time, in years (t = 7)

Now substituting, we get:

$F=P(1-r)^t\\F=51,000(1-0.1)^7\\F=51,000(0.9)^7\\F=24,393.14$

Rounding to nearest whole number,

Number of subscribers after 7 years = 24,393 subscribers

Calculate the total surface area of a pipe with inner surface area 1508.5 square cm, outer surface area 2514.2 square cm, and in

algol [13]

Answer:

The total surface area of the pipe is 4123.31 cm²

Step-by-step explanation:

Total surface area (TSA) of a pipe is calculated as;

Outer area of the pipe + Inner area of the pipe + cross section of the two ends

TSA = 2πRL + 2πrL + 2π(R² - r²)

TSA = 2π(RL + rL + R² - r²)

where;

R is the outer radius

r is the inner radius

L is length of the pipe

Determine the length of the pipe

Outer surface area of the pipe is calculated as;

outer surface of the pipe = 2πRL

2514.2 = 2πRL

2514.2 = (2π x 5) L

2514.2 = 31.42 L

L = 2514.2 / 31.42

L = 80.02 cm

Finally, determine the total surface area of the pipe

TSA = 2π(RL + rL + R² - r²)

TSA = 2π(5x80.02 + 3x80.02 + 5² - 3²)

TSA = 2π(400.1 + 240.06 + 16)

TSA = 2π(656.16)

TSA = 4123.31 cm²

Therefore, the total surface area of the pipe is 4123.31 cm²
