15 mph

3 hours

15 x 3 = 45 miles

Answer:

28.29 inch.

Step-by-step explanation:

So diameter is 9.

Circumference = pi x d

= 22/7 x 9

=28.29inch.

Answer:

I need the questions, for this graph, or at least the numbers

Step-by-step explanation:

Answer:

Surface area = 10.7 in.²

Step-by-step explanation:

Surface Area of triangular pyramid = BA + P*L

Base Area (BA) = ½*nh

b = 2 in.

h = 1.7 in.

BA = ½*2*1.7 = 1.7 in.²

Perimeter (P) = 2 + 2 + 2 = 6 in.

Slant height (L) = 3 in.

Plug in the values

Surface Area = 1.7 + ½*6*3

Surface area = 10.7 in.²

Answer:

8.94 if no rounding is necessary.

Step-by-step explanation:

Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...

8² + b² = 12²

64 + b² = 144

Subtract 64 from both sides...

64 - 64 + b² = 144 - 64

b² = 80

[tex]\sqrt{80}[/tex] = 8.94 if you're not rounding.

Answer:

The required sample size is 329.

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:

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

31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money.

This means that [tex]\pi = 0.31[/tex]

Confidence level is not given, so we assume 95%.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

What is the required sample size if you want to estimate this proportion with a margin of error of 0.05?

We need a sample size of n. n is found when M = 0.05. So

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

[tex]0.05 = 1.96\sqrt{\frac{0.31*0.69}{n}}[/tex]

[tex]0.05\sqrt{n} = 1.96\sqrt{0.31*0.69}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.31*0.69}}{0.05}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.31*0.69}}{0.05})^2[/tex]

[tex]n = 328.6[/tex]

Rounding up

The required sample size is 329.

Answer:

not

Answer:

non-equivalent

Step-by-step explanation:

the equivalend fraction of [tex]\frac{2}{3}[/tex] is [tex]\frac{6}{9}[/tex] not [tex]\frac{6}{10}[/tex]

Answer:

2

Step-by-step explanation:

[4^2/(-1+3)^3+2*10] / (10+1)

= [16/8+20] / 11

= 22/11

=2

Hope this helps :) Giving me brainiest would help a lot :))

Answer:

Step-by-step explanation:

I'll assume that all the angles are 90°, and there is no bottom to the box.

To determine the wood needed, calculate the surface area of the bed. Since there is no bottom or top to the box, the amount of wood is 2(45 in × 21 in) + 2(22 in × 21 in) = 1890 in² + 924 in² = 2814 in²

To determine the soil needed, calculate the volume of the box.

volume = 45 in × 21 in × 22 in = 20,790 in³

Answer:

pretty sure the answer is  x - y - 1 = 0

Answer:

29 degrees I believe

Step-by-step explanation:

If each triangle is worth 180 degrees, then the answer is 29 degrees.

Answer:

22/7 - irrational number

1.141141114 - irrational number

17/4 - rational number

-6 - integer

[tex]\frac{\pi }{2}[/tex] - irrational number

0 - whole number

9 - natural number and whole number

21/3 - natural number and whole number

Step-by-step explanation:

natural numbers would be numbers 1,2,3,4,5,6,7...

whole numbers would be numbers 0,1,2,3,4,5,6...

integers are negative whole numbers

rational numbers are fractions and numbers that have decimal points

irrational numbers are number such as [tex]\pi[/tex] or [tex]\sqrt{5}[/tex]

Answer:

0.2 is the answer

-your welcome and have a great day!!

Answer:

13 minutes and 30 seconds

Step-by-step explanation:

Okay so first you would divide 128 by 576. But since it takes her 3 minutes just to type 128 words you have to multiply 4.5 times 3. It will take her 13.5 minutes to type 576 words or 13 minutes and 30 seconds.

Answer:

332s+(27xm)

Step-by-step explanation:

because 27 is how much you save per month and you started off with 332

Answer:

In most cases, there are two types of functions that have horizontal asymptotes. Functions in quotient form whose denominators are bigger than numerators when x is large positive or large negative.

Answer:

370 million

Step-by-step explanation:

In the 10 years from 2000 to 2010, the population was multiplied by the factor ...

100% + 9.6% = 109.6% = 1.096

In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:

2030 population = (308 million)·(1.096²) ≈ 370 million

Answer:

b

Step-by-step explanation:

because if you look at it the x-coordinate is -6 and the y-coordinate is positive 4

Answer:

See the explanation

Step-by-step explanation:

When the numerator is less than the denominator, the result is always less than 1, that is 0. something and this will give a percentage less than 100, but when the numerator is greater than the denominator, th result is greater than 1, and any figure greater than 1 gives a percentage that is greater than 100

example

Numerator >Denominator

=4/2*100

=2*100

=200%

Numerator <Denominator

=2/4*100

=0/5*100

=50%

Let be a1 = 8 and a2 = 8 [ From question ]

We have to find out common differences which denoted by letter d .

d = a2 - a1 [ Formula ]

= 8 - 2

= 6

Thus,the common difference between successive terms in the sequence is 6 .

Answer:

6.

Step-by-step explanation:

We have to find out common differences which denoted by letter d .

d = a2 - a1 [ Formula ]

= 8 - 2

= 6

Also,

2+6=8 +6=14 +6=20 +6=26

So, It's Added Up By 6.

Answer:

1/4

Step-by-step explanation:

-1/2 in to -2/4

3/4+(-2/4)=1/4

Answer:

d=7

Step-by-step explanation:

divide both sides by 6

6d=42

d=42/6

d=7

Answer:

A. Transform Boundary

Step-by-step explanation:

Transform boundaries are places where plates slide sideways past each other

Divergent Boundaries occur  when two tectonic plates move away from each other

Convergent Boundaries are when both the plates collide into each other

Subduction boundaries are when one plate bends and slides underneath the other curving down into the mantle

Hope this helps dude

Answer: no learn it urseld caca haha

Step-by-step explanation:

Step-by-step explanation:

Here's your solution

=> Base = 32 In

=> Height = 30 in

=> Area of traingle = 1/2*base *height

=> putting the value of base and height in formula

=> Area = 1/2*30*32

=> Area = 480 in sq
