Answer:

hypotenuse = 2879

Step-by-step explanation:

By alternate interior angles, the angle on the base of the triangle is 10o.

So what you have here is a trig question, so you have to relate the hypotenuse and the side opposite with 10 degrees.

One of the six Trig functions = opposite / hypotenuse

One of the six Trig functions =500 / x

You are actually using the Sine function.

Sin(10) = 500/x

Sin(10) = 0.1736

0.1736 = 500 / x       Multiply both sides by x

0.1736 * x = 500 /x * x

0.1736 * x = 500       Divide both sides by 0.1736

0.1736x/0.1736 = 500 / 0.1736

x = 2879

So the hypotenuse is 2879.

The number of students who chose lunch was 5 more than the number of students who chose breakfast. Write a system of linear equa
Papessa [141]

Answer:

The system of linear equations are y=5+x and  x+y=25

Step-by-step explanation:

Given : The number of students who chose lunch was 5 more than the number of students who chose breakfast. Let x represent the number of students who chose breakfast and y represent the number of students who chose lunch.

(50 students picked, 25 picked dinner the rest picked lunch and breakfast)

To find : Write a system of linear equations that represents the numbers of students who chose breakfast and lunch ?

Solution :

The number of students who chose breakfast be 'x'

The number of students who chose lunch be 'y'.

The number of students who chose lunch was 5 more than the number of students who chose breakfast.

i.e. y=5+x

Now, Total student were 50 and 25 picked dinner the rest picked lunch and breakfast i.e. 25.

So, x+y=25

Therefore, the system of linear equations are y=5+x and  x+y=25

Two men walk at rates of 6 miles per hour and 10 miles per hour, respectively. Simultaneously, they started from the same place
alina1380 [7]

The time taken by the two men will be equal to 26 hours

<h3>What is speed?</h3>

The speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance.

here two men are walking at different speeds like

v₁=6 miles per hour

v₂=10 miles per hour

The time taken by them to separated by the distance of 100 miles each so that both of them separated by the distance of 200 miles.

t₁= {100}/{6}=16.66 hours

t₂= {100}/{10}=10 hours

total time taken will be

t₁+t₂=16.66+10=26.66 hours
