Answer:

120 miles

Step-by-step explanation:

just take 24*5 to get how many miles they can travel which would be 120 miles

Answer:

1 mi 1927 ft

Step-by-step explanation:

Turn everything into feet:

5mi x 5280 ft/1 mi  = 26,400ft + 1,348 ft = 27, 748 ft

3mi x 5280 ft/1 mi = 15,840ft + 4,701 ft = 20,541 ft

Do the subtration that the problem wants you to do:

27, 748 ft - 20,541 ft = 7,207 ft

Turn the answer into mi & ft:

7,207 ft - 5280 ft = 1927 ft

=

1 mi 1927 ft

Answer:

$45.90

Step-by-step explanation:

What 15% off means is 85% of the original price ($54). 85% is the same as 17/20. Multiply 17/20 by 54 (or multiply 3/20 by 54 and subtract that from 54) to get the sale price.

(17 * 54)/20 (Multiply 17 by 54)

918/20 (Reduce if needed)

459/10 (Divide 459 by 10)

45.9

The sale price of the comforter is $45.90.

Answer:

see explanation below

Step-by-step explanation:

You have three pairs of shoes (white, brown, and black), and you have 6 pairs of pants ( brown,  blue, grey, white, sand, and  black)

We use the Fundamental Counting Principle to find the number of possible pant-shoe combinations:

3 * 6 = 18

then we can find the probability of wearing by random selection brown shoes with either blue or grey pants:

prob (brown shoes & blue pants) + prob (brown shoes & grey pants) =

= 1/18 + 1/18 = 2/18 = 1/9

Let's solve your equation step-by-step.

x3+5x2+2x+10=0

Step 1: Factor left side of equation.

(x+5)(x2+2)=0

Step 2: Set factors equal to 0.

x+5=0 or x2+2=0

x=−5

Answer:

x=−5

Answer:

C is the answer i think

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

[tex]\left \{ {{2x+y=10,3} \atop {3x+y=14,8}} \right.[/tex]

[tex]\left \{ {{y=10,3-2x} \atop {y=14,8-3x}} \right.[/tex]

10,3-2x=14,8-3x

x=4,5 - one hamburger

y=1,3 - one milk shake

OR:

$14,8-$10,3=$4,5 - one hamburger

2*4,5+y=10,3

y=1,3 - one milk shake

2y=2,6

Answer:

first one is the answer to this

Step-by-step explanation:

Answer:

This answer is C, it is on the perpendicular bisector of segment LC.

Draw any line segment P and L, then another point C anywhere, but the length needs to be the same as PL.  You will note that LC (if you connect those points) will become the perpendicular bisector to point P.

I hope that makes sense.....

Answer:

√10/2x

Step-by-step explanation:

Multiply by √6 on the top and bottom to rationalize the denominator.

(√15×√6)/(√6x×√6) = √90/6x = (√9×√10)/6x = 3√10/6x = √10/2x

Answer:

Uh 7/24?

Answer:

A. 67.8%

Step-by-step explanation:

the total number of occurences are 202

Now the total number of occurencess for 4 and below are 137

So Heres the quickest way to do it: Divide 137 by 202 then multiply it by 100 being 100%

Then you would get 67.8, then well put the percent sign behind it.

The correct answer is C) 54.34°.

2.4m2/2m +6m/2m =2m+3

4.10m2 /5m +15m/5m= 2m+3

Answer:

The answer is 48

Step-by-step explanation:

160% is the same as 1.60

A percent of something means you have to multiply them together

1.60 times 30=48

Answer:

358 randomly selected air passengers must be surveyed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

98% confidence level

So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].

Assume that a prior survey suggests that about 22​% of air passengers prefer an aisle seat.

This means that [tex]\pi = 0.22[/tex]

How many randomly selected air passengers must you​ survey?

We need a sample of n, and n is found for which [tex]M = 0.051[/tex]. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.051 = 2.327\sqrt{\frac{0.22*0.78}{n}}[/tex]

[tex]0.051\sqrt{n} = 2.327\sqrt{0.22*0.78}[/tex]

[tex]\sqrt{n} = \frac{2.327\sqrt{0.22*0.78}}{0.051}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.22*0.78}}{0.051})^2[/tex]

[tex]n = 357.2[/tex]

Rounding up

358 randomly selected air passengers must be surveyed.

Answer:

  mm:ss = 11:40

Step-by-step explanation:

We assume the amount of gain is proportional to the time that passes.

  g/7 = 5/3

  g = 7(5/3) = 35/3 = 11 2/3 . . . . minutes

The clock will have gained 11 minutes and 40 seconds after 7 days.
