Example Question #11 : How To Find The Perimeter Of A Figure

What is the perimeter of a square with a side length of a-1 $\displaystyle a-1$ ?

Possible Answers:

4a+4 $\displaystyle 4a+4$

a^2-4 $\displaystyle a^2-4$

4a^2-4 $\displaystyle 4a^2-4$

4a-4 $\displaystyle 4a-4$

a-4 $\displaystyle a-4$

Correct answer:

4a-4 $\displaystyle 4a-4$

Explanation:

Write the perimeter formula for a square.

P=4s $\displaystyle P=4s$

Substitute the side length in the formula and simplify.

$\displaystyle P=4(a-1)= 4a-4$

Example Question #263 : Problem Solving

A circle has radius 8. The circumference of the circle is 40% of what number?

Possible Answers:

$25 \pi$ $\displaystyle 25 \pi$

$2 0 \pi$ $\displaystyle 2 0 \pi$

$40 \pi$ $\displaystyle 40 \pi$

$80 \pi$ $\displaystyle 80 \pi$

Correct answer:

$40 \pi$ $\displaystyle 40 \pi$

Explanation:

The circumference of a circle is its radius mulitplied by $2 \pi$ $\displaystyle 2 \pi$ . The radius is 8, so the circumference is

$8 \cdot 2 \pi = 16 \pi$ $\displaystyle 8 \cdot 2 \pi = 16 \pi$ .

To find the number of which this is 40%, divide this by 40%, or $\frac{40 }{100}$ $\displaystyle \frac{40 }{100}$ :

$16 \pi \div\frac{40 }{100} = 16 \pi \div\frac{2}{5} = 16 \pi \cdot \frac{5} {2} = \frac{80 \pi} {2} = 40 \pi$ $\displaystyle 16 \pi \div\frac{40 }{100} = 16 \pi \div\frac{2}{5} = 16 \pi \cdot \frac{5} {2} = \frac{80 \pi} {2} = 40 \pi$

Example Question #61 : Geometry

$\bigtriangleup ABC \sim \bigtriangleup DEF$ $\displaystyle \bigtriangleup ABC \sim \bigtriangleup DEF$ .

$\angle B$ $\displaystyle \angle B$ is a right angle.

$m \angle C = 45 ^{\circ }$ $\displaystyle m \angle C = 45 ^{\circ }$ .

Is $\bigtriangleup DEF$ $\displaystyle \bigtriangleup DEF$ scalene, isosceles, or equilateral - or can it be determined?

Possible Answers:

$\bigtriangleup DEF$ $\displaystyle \bigtriangleup DEF$ is an equilateral triangle.

$\bigtriangleup DEF$ $\displaystyle \bigtriangleup DEF$ is a scalene triangle.

$\bigtriangleup DEF$ $\displaystyle \bigtriangleup DEF$ is a isosceles triangle, but not equilateral.

Whether $\bigtriangleup DEF$ $\displaystyle \bigtriangleup DEF$ is scalene, isosceles, or equilateral cannot be determined.

Correct answer:

$\bigtriangleup DEF$ $\displaystyle \bigtriangleup DEF$ is a isosceles triangle, but not equilateral.

Explanation:

Corresponding angles of similar triangles are congruent, so

$m \angle E = m \angle B = 90 ^{\circ }$ $\displaystyle m \angle E = m \angle B = 90 ^{\circ }$

$m \angle F = m \angle C = 45 ^{\circ }$ $\displaystyle m \angle F = m \angle C = 45 ^{\circ }$

The degree measures of the angles of a triangle total 180, so

$m \angle D =180^{\circ } - (m \angle F +m \angle E )$ $\displaystyle m \angle D =180^{\circ } - (m \angle F +m \angle E )$

$m \angle D =180^{\circ } - (90^{\circ } +45^{\circ } ) = 45^{\circ }$ $\displaystyle m \angle D =180^{\circ } - (90^{\circ } +45^{\circ } ) = 45^{\circ }$

Since $\angle D$ $\displaystyle \angle D$ and $\angle F$ $\displaystyle \angle F$ are congruent, by the Isosceles Triangle Theorem,

$\overline{EF} \cong \overline{DE}$ $\displaystyle \overline{EF} \cong \overline{DE}$

making $\bigtriangleup DEF$ $\displaystyle \bigtriangleup DEF$ isosceles.

Example Question #263 : Problem Solving

A ladder 30 feet long leans against a house. The top of the ladder is $\displaystyle N$ feet above the ground. In terms of $\displaystyle N$ , how far along the ground is the bottom of the ladder from the house?

Possible Answers:

30 + N $\displaystyle 30 + N$

$\sqrt{900 + N^{2}}$ $\displaystyle \sqrt{900 + N^{2}}$

$\sqrt{900 - N^{2}}$ $\displaystyle \sqrt{900 - N^{2}}$

30 - N $\displaystyle 30 - N$

Correct answer:

$\sqrt{900 - N^{2}}$ $\displaystyle \sqrt{900 - N^{2}}$

Explanation:

The ladder, which is 30 feet long, is the hypotenuse of a right triangle whose legs are the line from the top of the ladder to the ground, which has length $\displaystyle N$ feet, and the line from the bottom of the ladder horizontally to the house, whose length we will call $\displaystyle M$ feet. See the diagram below.

Ladder

By the Pythagorean Theorem,

$M^{2}+N^{2} = 30 ^{2} = 900$ $\displaystyle M^{2}+N^{2} = 30 ^{2} = 900$

Solving for $\displaystyle M$ :

$M^{2}+N^{2} - N^{2} = 900 - N^{2}$ $\displaystyle M^{2}+N^{2} - N^{2} = 900 - N^{2}$

$M^{2}= 900 - N^{2}$ $\displaystyle M^{2}= 900 - N^{2}$

$M = \sqrt{900 - N^{2}}$ $\displaystyle M = \sqrt{900 - N^{2}}$ , the correct choice.
