Answer:

<em>40 miles per hour. </em>

Step-by-step explanation:

\frac{1}{4} ÷ 22.5 = \frac{1}{4} × \frac{2}{45} = \frac{1}{90} mile per second

\frac{1}{90} × 3600 = <em>40 miles per hour.</em>

A.

You have to convert 22.5 seconds to hours

1st you have to go from seconds -> minutes:
22.5 seconds x 1min / 60secs = 0.375mins

2nd go from minutes to hours:
0.375mins x 1hr / 60minutes = 0.00625hours

Since it is miles per hour, miles would go on top and hours (or seconds in this this case) would go on the bottom.

To find miles per hour:

(1/4) miles / 0.00625 hours = 40 miles per hour.

Therefore, hyena runs 40 miles per hour.

Zoe has 1500 beads. She wants to make 6 friendship bracelets. She needs 215 beads for each bracelet. How many beads will Zoe hav
drek231 [11]
First you would need to find out how many beads are needed for the bracelets.

215 beads per bracelet x 6 bracelets = 1290 beads

This tells us that to make all 6 bracelets, it will use up 1290 beads, now subtract that from your total number of beads.

1500-1290= 210

So Zoe will have 210 beads left over. Since this is a word problem, it is best to answer it in the same format:

Zoe will use 1290 beads to make 6 friendship bracelets. After all of the bracelets are made, she will have 210 beads left over.

hope this helps!

DerKrebs [107]
The angle that is between the segments NM and PN is the angle that their segments form. If we take away the side PM (in our heads), we can see that the angle formed is angle N, or angle PNM.

What is the domain of f(x) = (1/3)^x ?
olya-2409 [2.1K]

Answer:

B

Step-by-step explanation:

There isn't any number that x can't be. Start with a graph to show how this could be so.

It is easy to see that x > 0 gives a line that goes very near the x axis. It is not quite so easy to see that it never touches the x axis. But if you recreate the graph in  Desmos, you will see that is true if you spread the x's out.

It is not quite so easy to see that when x<0 the graph tips upward very quickly but again if you move the values of the axis around you will see there is no value that x cannot be.

In the 1939 movie The Wizard of Oz, upon being presented with a Th.D. (Doctor of Thinkology), the Scarecrow proudly exclaims, "T
Brilliant_brown [7]

Answer:

The Scarecrow got it wrong.

Step-by-step explanation:

1. The Pythagoras theorem does not apply to every isosceles triangle. It only applies to a triangle that has one of its sides as a right angle i.e. 90 degrees.

2. The Pythagoras theorem deals with squares of sides not square roots of sides.

3. Pythagoras theorem does not state that the square of any side is equal to the sum of the remaining two. Instead, it states that the square of the hypotenuse of a right angled triangle is equal to the sum of the square of the remaining two sides.

4. The Pythagoras theorem does not mention anything about an isosceles triangle. It deals only with Right angled triangles.
