A 'snail's pace is 60 inches per minute. At this rate how long will it take the snail to crawl 120 feet?
True [87]
Ok, so here, we have the unit rate of the snail. Now, we need to set up a proportion.

60/1 = 120/x

Now, cross multiply.

60*x = 120*1

60x= 120

Now divide to solve for x.

60x/60 = 120/60
x = 120/60 
x= 2

Now our final answer is 2.

Final answer:- The snail will take 2 minutes to crawl 120 feet

QUICK QUESTION! PLEASE ANSWER FAST!
nignag [31]

Answer:

I think √170

Step-by-step explanation:

The points are A: (-3,5) and (4,-6) so we plug this into the distance formula

√(x2-x1)^2+(y2-y1)^2

√(4-(-3))^2+(-6-5)^2

√(7)^2+(-11)^2=

√49+121= √170 or a really long decimal which starts out 13.038404810

If I got the points wrong I can redo the problem and get another answer but I did the problem on my own and used a calculator and got the same answer

Which of the following statements are true of the parabola shown?
Vesna [10]

<u>True statements are:</u>

  • It has a directrix of x = - 4.
  • It has a focus at (4, 0).

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

We have the following statements to check on whether it's right or wrong:

<u>1. It has a directrix of x = -4:</u>

According to figure , parabola directrix is at -4 i.e. at x = -4 , Therefore this statement is true!

<u>2. It opens to the left:</u>

In figure, Parabola opens to right not left , Therefore this statement is wrong!

<u>3. It has a vertex at the origin:</u>

Vertex of Parabola is at what points not shown in figure. Therefore this statement cannot be confirmed as true.

<u>4. The axis of symmetry is the y-axis:</u>

Axis of symmetry for above parabola is x-axis as it cuts parabola into two equal halves , y-axis doesn't do this ! Therefore this statement is wrong!

<u>5. It has a focus at (4, 0):</u>

Parabola focus is at F(4,0) on x-axis . And so, Therefore this statement is true!
