Hello!

If the digit just to the right of it is less than 5, drop the digit to the left one. If the digit is greater than 5, you round it to the next decimal. So, the answers are:

2.6 rounded = 3 because 6 is greater than 5.

1.8 rounded = 2 because 8 is greater than 5.

4.2 rounded = 4 because 2 is less than 5.

3.3 rounded = 3 because 3 is less than 5.

I hope you found this helpful! c:

Nina [5.8K]
Three hours after the bus starts out, it's 150 miles ahead of the truck. Then the truck starts out, and it gains (65-50)=15 miles on the bus every hour. If neither of them ever stops for anything, the truck will catch up to the bus in ( 150/15 ) = 10 hours. . . . (The hint is useless.)

Eliminate the parameter,t, in the parametric equation, x=6cos t, and y =3 sin t
german
X = 6 cos(t) 
y = 3 sin(t)

we can rewrite these equations as:

\frac{x}{6}=cost(t) \\ \\ \frac{y}{3} =sin(t)

Taking squares of both equations we get:

( \frac{x}{6})^{2}=sin^{2} (t) \\  \\ 
( \frac{y}{3})^{2}=cos^{2}(t)

Adding both the equations, we get:

\frac{ x^{2} }{36}+ \frac{ x^{2} }{9}=sin^{2}(t)+cos^{2}(t)   \\  \\ 
 \frac{ x^{2} }{36}+ \frac{ x^{2} }{9}=1

A train travels from New York City to Washington D.C. and then back again. The table below shows the number of Coach tickets sol
alisha [4.7K]

Answer:  $74

<u>Step-by-step explanation:</u>

Let C represent the cost of a coach ticket

Let B represent the cost of a business ticket

Washington: 150C +  50B = 18,450

NY City:         170C + 100B = 27,280

Solve the system using the Elimination method:

-2(150C +  50B = 18,450)   →   -300C - 100B = -36,900

1(170C + 100B = 27,280)   →     <u>170C + 100B =  27,280  </u>

                                                 -130C             =  - 9,620

                                             <u>  ÷ -130              </u>  <u> ÷   -130    </u>

                                                          C            =      74
