A car is traveling at 25 miles per hour during rush hour. How far does the car travel in
2 minute and 45 seconds?

Answers

Answer: 1.14583333333 miles

Step-by-step explanation: divide 25/21.81818181818182

The car will travel 1.15 miles in 2 minutes 45 secs

if a car is traveling at 25 miles per hour, the amount of time the car travels in secs is 3600secs

25 miles  = 3600secs

To get the distance traveled in 2 minutes 45 secs, we can write;

x = 165 secs

Divide both expressions

25/x = 3600/165

3600x = 25 * 165

3600x = 4125

x = 1.15 miles

Hence the car will travel 1.15 miles in 2 minutes 45 secs

Line j has an equation of y = 1/5x + 7. Perpendicular to line j is line k, which passes through
the point (-1, -3). What is the equation of line k?
Write the equation in slope-intercept form. Write the numbers in the equation as simplified
proper fractions, improper fractions, or integers.

Answers

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]\begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\qquad \impliedby y=\stackrel{\stackrel{m}{\downarrow }}{\cfrac{1}{5}}x+7 \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{\cfrac{1}{5}}\qquad \qquad \qquad \stackrel{reciprocal}{\cfrac{5}{1}}\qquad \stackrel{negative~reciprocal}{-\cfrac{5}{1}\implies -5}}[/tex]

so then line K has a slope of -5 and pass through (-1, -3)

[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{-3})\qquad \qquad slope=m=-5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-3)}=\stackrel{m}{-5}[x-\stackrel{x_1}{(-1)}] \\\\\\ y+3=-5(x+1)\implies y+3=-5x-5\implies y=-5x-8[/tex]

Green Valley High School recently completed an expansion. Of the new classrooms, 11 are math
classrooms, 8 are science classrooms, and 6 are history classrooms. If a single classroom is picked at
random, what is the probability that the classroom is for math or history?

Answers

Answer: 68%

Step-by-step explanation:

The best way to do this is add up the number of math and history rooms, and divide that by the total number of rooms.

There are 17 total math and history rooms, and 25 rooms total.

17/25 = .68

Multiply that by 100 to get the percent and the answer is 68%

What is the value of x?

Answers

Answer:

x = 10.

Step-by-step explanation:

(5x-1) + (8x+5) + (4x+6) = 180   (the 3 angles in a triangle sum to 180 degrees).

5x + 8x+ 4x - 1 + 5 +6  = 180

17x + 10 = 180

Many things that we use every day, like televisions, computers, refrigerators, and microwaves, require energy in order to work. We also rely on energy to make a car run and to heat water. All of the energy that we need to use must first be produced. Some sources of energy, such as gas and oil, can be harmful to the environment. Burning gas and oil can pollute the air. Also, gas and oil are limited, and we are using up the small amount that is left on the planet. This is why people should use alternative energy sources, which do not pollute the environment and are plentiful. Solar and wind energy are clean energy sources that should be used more often to reduce the pollution on Earth.Which text structure does the author use to organize the passage?
