What is the value of the expression “three less than the quotient of ten and a number, increased by six” when n = 2?

alisha [4.7K]

Answer:

Step-by-step explanation:

The given expression is "three less than the quotient of ten and a number, increased by six”

The quotient of ten and a number increased by six is translated into mathematical expression as:

$\frac{10}{n}+6$

Three less than the quotient of ten and a number, increased by six is

$(\frac{10}{n}+6)-3$

When we substitute n=2, we get:

$(\frac{10}{2}+6)-3$

Divide to get:

$(5+6)-3$

Add to get:

$11-3$

Subtract

$8$

The length around the outside of semicircle O from point L through point M to point N is 14 centimeters. The perimeter of semici

Luden [163]

The area would be 83.67 cm.

A semicircle is half of a circle. The perimeter of the semicircle would be half of the perimeter (circumference) of the entire circle. The formula for circumference is:

C=πd

Using our information, we have

22.92 = 0.5(3.14)d
22.92 = 1.57d

Divide both sides by 1.57:

22.92/1.57 = 1.57d/1.57
14.6≈d

Since the diameter is 14.6, the radius is 14.6/2 = 7.3.

We use the radius for the area of the semicircle:

A=0.5πr²
=0.5(3.14)(7.3)²
=83.67

Artemon [7]

The volume of a cone is (1/3) that of its similar cylinder.
Thus the volume of the cone B would be: $6 \pi cm^{3}$
