The area of a triangle is 225 in^2. If the width is 18 inches, find the height of the triangle

sergiy2304 [10]

$\textit{area of a triangle}=\cfrac{1}{2}\cdot b\cdot h\qquad 
\begin{cases}
b=\textit{base of triangle,}\\
\qquad \textit{may also be its width}\\
h=\textit{height of triangle}
\end{cases}
\\ \quad \\
b=width=18\qquad area=225
\\ \quad \\
225=\cfrac{1}{2}\cdot 18\cdot h\impliedby \textit{solve for "h"}$

What is tan C ?

MatroZZZ [7]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC of the figure, the tangent of angle C is equal to divide the opposite side to angle C (side AB) by the adjacent side to angle C (side BC)

$tan(C)=\frac{AB}{BC}$

substitute the given values

$tan(C)=\frac{11}{22}$

simplify

$tan(C)=\frac{1}{2}$

In Ms.Khans class,22 out of 25 students hand in their projects on time. What percent of the class hand in their projects on time

Nikitich [7]

88 % students of the class hand in their projects on time

Solution:

Given that, Ms.Khans class, 22 out of 25 students hand in their projects on time

Total number students = 25

Students hand in their projects on time = 22

To find: percent of the class hand in their projects on time

$\text{ percent of class hand in time } = \frac{\text{Students hand in projects on time}}{\text{total students}} \times 100$

Substituting the values, we get

$\text{ percent of class hand in time } = \frac{22}{25} \times 100\\\\\text{ percent of class hand in time } = 0.88 \times 100\\\\\text{ percent of class hand in time } = 88$

Thus 88 % students of the class hand in their projects on time

You and a friend plan to see 2 movies over the weekend. You can choose from 6 comedy, 2 drama, 4 romance, 1 science fiction, or

Debora [2.8K]

There are a total of 16 movies to choose from and 6 of them are comedy. This means that you have a 38% of choosing comedy. But the chances of you not choosing comedy is 62%. And since your friend is also choosing, the chance of neither of you not choosing is cut in half.

So, the final answer of neither of you choosing comedy is 31%

(I don't know whether it's dependent or independent)
