M-(M x 0.16) and M-(.84) because the first one you need to multiply to find what 16% of m is then subtract that by m for the second one you subtract.

Which is not a true statement?

lyudmila [28]

Answer:

B 10.211 < 10.210

Step-by-step explanation:

Evaluating each of the given statements one by one:

A 10.345 > 10.340

Decimal values at the tenth and hundredth place are the same on both sides while the thousandth part value is greater on the left side.

Hence, this statement is true

B 10.211 < 10.210

Decimal values at the tenth and hundredth place are the same on both sides while the thousandth part value is greater on the left side.

Hence , this statement is not true because 10.211>10.210

C 9.999 < 10.0

This statement is true because 9.999 is less than 10.

D 6.3 = 6.30

This statement is correct as the left hand side is the same as right hand side.

The population of a town has grown at an annual rate of 2.7%. How long does it take for it’s population of 18,450 people to doub

charle [14.2K]

It would take 26 years.

The equation will be in the form y = a(1+r)ˣ, where a is the initial population, r is the growth rate as a decimal number, and x is the amount of time. Using our information we have

y = 18450(1+0.027)ˣ = 18450(1.027)ˣ

We want the population to be doubled; 18450*2 = 36900:
36900 = 18450(1.027)ˣ

Divide both sides by 18450:
36900/18450 = 18450(1.027)ˣ/18450
2 = 1.027ˣ

Using logarithms, we have
$\log_{1.027}2=x
\\
\\x=26.017$

What is the length of the longest side ?

exis [7]

Answer:

11 feet (Option C)

Step-by-step explanation:

Let the longer side be l and the shorter side be b.

We know that,

→ Perimeter of rectangle = 2 ( longer side + shorter side )

Here,

Perimeter of rectangle is 32 feet.

→ 32 = 2 (l + b)

→ 32 = 2l + 2(5)

→ 32 = 2l + 10

→ 32 - 10 = 2l

→ 22 = 2l

→ $\sf \dfrac{22}{2}$ = l

→ 11 = l

→ 11 feet = longer side

$\therefore$ Length of the longer side is 11 feet.
