Find the area of the shaded region of the trapezoid.

myrzilka [38]

Answer:

Step-by-step explanation:

Area of Trapezoid

Area = (b1 + b2)*h/2

Area = (9 + 13)*11 /2

Area = (22) * 11/2

Area = 121 sqr. units.

Area of the unshaded triangle

Area = 1/2 b * h

Area = 1/2 9 * 11

area = 49.5

Area of the shaded region

Area = 121 - 49.5

Area = 71.5

Three freshmen, 3 sophomores, 3 juniors, and 3 seniors are participating on the debate team. The team's captain is randomly sele

slega [8]

Answer:

C) $\frac{3}{4}$

Step-by-step explanation:

Given:

Number of freshmen = 3

Number of sophomores =3

Number of juniors =3

Number of seniors = 3

The team's captain is randomly selected from any grade level.

To find the the probability that a freshman will not be selected as captain.

Solution:

Total number of members in the team = $3+3+3+3$ = 12

Probability that a freshman will be selected as captain will be:

⇒ $\frac{Number\ of\ freshmen}{Total\ members}$

⇒ $\frac{3}{12}$

Reducing to simple fraction by dividing numerator and denominator by 3.

⇒ $\frac{3\div3}{12\div 3}$

⇒ $\frac{1}{4}$

Thus, probability that a freshman will not be selected as captain will be given as:

⇒ $1-\frac{1}{4}$

Taking LCD.

⇒ $\frac{4}{4}-\frac{1}{4}$

Subtracting the numerators.

⇒ $\frac{3}{4}$ (Answer)

A scale drawing has a scale of 1/4in:12ft. Find the length on the drawing for each actual length. 15 ft.

leonid [27]

So the ratio is at ¼ : 12, namely the drawing has ¼ inch to an actual 12 feet.

so, what would it be for an actual 15 feet on the drawing then?

$\bf \begin{array}{ccll}
\stackrel{inches}{drawing}&\stackrel{feet}{actual}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{1}{4}&12\\\\
d&15
\end{array}\implies \cfrac{\quad \frac{1}{4}\quad }{d}=\cfrac{12}{15}\implies \cfrac{\quad \frac{1}{4}\quad }{\frac{d}{1}}=\cfrac{12}{15}
\\\\\\
\cfrac{1}{4}\cdot \cfrac{1}{d}=\cfrac{12}{15}\implies \cfrac{1}{4d}=\cfrac{12}{15}\implies 15=48d\implies \cfrac{15}{48}=d\implies \cfrac{5}{16}=d$
