No.

\sqrt{45}=3\sqrt{5}  \\2\sqrt{20} =2\sqrt5}

If you add them up you DO NOT GET 5\sqrt{5}. According to mathematics, it equals to 7\sqrt{5}.

1. The ratio of the number of boys to the number of girls on the swim team
Papessa [141]

Answer:

8

Step-by-step explanation:

Sum the parts of the ratio 4 + 2 = 6 parts

Divide 24 by 6 to find the value of one part of the ratio

24 ÷ 6 = 4 ← value of 1 part, thus

number of boys = 4 × 4 = 16

number of girls = 2 × 4 = 8

Hence there are 8 more boys than girls

Explain why the graphing calculator cannot be used to solve or approximate solutions to all polynomial equations.
Lelu [443]
Let's put it this way:  If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>

Nastasia [14]

Answer:

  a. 2 7/9 miles

  b. 21.6 minutes

  c. 8 1/3 miles

Step-by-step explanation:

The rate at which Catlin runs can be determined from the graph by finding the coordinates of a grid point that lies on the line. The line goes through the origin, so the relationship between time and distance is proportional.

We see that the point (miles, minutes) = (1 2/3, 12) lies on the graph, so the contant of proportionality is ...

  k = y/x = 12/(5/3) = 36/5 = 7.2 . . . . minutes/mile

__

<h3>a.</h3>

The proportion can be written ...

  distance/(20 minutes) = (1 mile)/(7.2 minutes)

  distance = (20/7.2) miles = 2 7/9 miles

Catlin will run 2 7/9 miles in 20 minutes

__

<h3>b.</h3>

The proportion can be written ...

  time/(3 miles) = (7.2 minutes)/(1 mile)

  time = (3)(7.2 minutes) = 21.6 minutes

Catlin was running 21.6 minutes

__

<h3>c.</h3>

In 1 hour, Catlin will run 3 times as far as in 20 minutes. Using the result from part A, we find ...

  3(2 7/9 miles) = 8 1/3 miles 8 1/3 miles

Catlin will run 8 1/3 miles in one hour.

_____

<em>Additional comment</em>

Once we have a relationship between minutes and miles, we can write proportions with either of those numbers in the numerator or denominator. We find it convenient to put the unknown value in the numerator of a proportion, which is why the ratios are written differently in the different parts of the problem.

Please help me <br> 10 points
Nonamiya [84]

Answer:

  see below

Step-by-step explanation:

The following definitions apply:

  if p, then q . . . . conditional statement

  if q, then p . . . . converse

  if ~p then ~q . . . inverse

  if ~q then ~p . . . contrapositive

You have ...

  p = "it is October 31"

  q = "it is Halloween"

(a) The <em>converse</em> is ...

  If it is Halloween, then it is October 31.

(b) The <em>inverse</em> is ...

  If it is not October 31, then it is not Halloween.

(c) The <em>contrapositive</em> is ...

  if it is not Halloween, then it is not October 31.
