An airplane flies a distance of 650km at an average speed of 300 km/h. How much time did the flight take?

Answers

To solve this, you can set up a proportion and cross multiply. 

(650)/(x)= (300)/(1)   \n  \n 650*1=300*x \n  \n 650=300x \n  \n 2.17=x

2.17 hours
Distance x speed = time
300 x 650
=195000
Checking
Distance divide time = speed
195000 divide 600
=300

What is the value of P for the following triangular prism?

Answers

pretty sure its 36 (not sure) i keep getting 36.6 cm

Answer:

4cm + 2.8cm +4cm = 10.8 cm

Step-by-step explanation:

Formula Perimeter is A+B+C

First, you need to change the 28 mm to cm (move decimal once space to the left making 28mm to 2.8 cm)  

Next, add all your sides that are now in the same format of cm

4 +2.8 +4=10.8 cm

if the CD is $14.95, you subtract $7.55 from the $14.95 and your answer would  be $7.40

1. Refer to the equation 3x - 2y = -18 Complete the table of values for at least 2 points. Show your work.Use the table of values to graph the line.

2. Use the equation y = 4x to answer the questions. Graph y = 4x.
What is the slope of y = 4x and what does this mean?

Answers

Part 1

For the given equation 3x-2y=-18, complete the table:

1) when x=0, then

3\cdot 0-2y=-18,\n -2y=-18,\n y=9;

2) when y=0, then

3x-2\cdot 0=-18,\n 3x=-18,\n x=-6;

3) when x=2, then

3\cdot 2-2y=-18,\n -2y=-24,\n y=12;

4) when x=4, then

3\cdot 4-2y=-18,\n -2y=-30,\n y=15.

Therefore, the table is

\begin{array}{ccccc}x&0&2&4&-6\ny&9&12&15&0\end{array}

With these data you can plot the graph of the function (see 1st diagram).

Part 2

The graph of the function y=4x is represented in the second diagram. The slope of the line is m=4.
