Aleksandr-060686 [28]

Answer:

\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1}, \\\\GI=5.0

Step-by-step explanation:

In any right triangle, the following is true:

The sine of any angle is equal to its opposite side divided by the hypotenuse of the triangle. (o/h)

The cosines of any angle is equal to its adjacent side divided by the hypotenuse. (a/h)

The tangent of any angle is equal to its opposite side divided by its adjacent side. (o/a)

Thus,

\text{3. }\\\tan D=\frac{7}{4},\\\\\sin D=\frac{7}{8.1}, \\\\\cos D=\frac{4}{8.1},

\text{4. }\tan 68^{\circ}=\frac{GI}{2},\\GI=2\tan68^{\circ}=4.95017370683\approx \boxed{5.0}

Alex787 [66]

The number of teachers is 4 and number of students is 10 on the trips if the tickets were $22.00 each for teachers and $8.50 each for students.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

In Maths museum tickets were $22.00 each for teachers and $8.50 each for students, and the group paid $173.00 in total.

Let's suppose the number of teachers is x and number of students is y

22x + 8.5y = 173 ...(1)

5.5x + 2y = 42  ...(2)

After solving the above equation by substitution method we get;

From equation (1):

Multiply by 2 with equation (1)

\rm x=\dfrac{346-17y}{44}

\rm 5.5\cdot \dfrac{346-17y}{44}+2y=42

y = 10

\rm x=\dfrac{346-17\cdot \:10}{44}

x = 4

Thus, the number of teachers is 4 and number of students is 10 on the trips if the tickets were $22.00 each for teachers and $8.50 each for students.
