Which one is it A, B, C, or D?

Answer:

Penguins can swim at a speed of 19.77 miles per hour.

Step-by-step explanation:

Since penguins can swim at speeds of up to 29 feet per second, to convert this speed to miles per hour, knowing that 1 mile is equal to 5280 feet, the following calculation must be performed:

1 hour = 60 minutes

1 minute = 60 seconds

1 hour = 60x60 seconds = 3,600 seconds

29 x 3,600 = feet per hour = 104,400

104,400 / 5,280 = miles per hour = 19.77

Thus, penguins can swim at a speed of 19.77 miles per hour.

Answer:

2. c) 1050 mm³

3. c) 8 yards.

Step-by-step explanation:

Given the following data;

Length = 25mm

Width = 7 mm

Height = 6 mm

To find the volume of the rectangular prism;

Volume of rectangular prism = base area * height

First of all, we would determine the base area;

Base area = length * width

Base area = 25 * 7

Base area = 175 mm²

Next, we find the volume;

Volume of rectangular prism = 175 * 6

Volume of rectangular prism = 1050 mm³

Question 2.

Given the following data;

Length = 9 yards

Width = 7.5 yards

Volume = 540 cubic yards

To find the height of the rectangular prism, x;

Volume of rectangular prism = length * width * height

540 = 9 * 7.5 * x

540 = 67.5x

x = 540/67.5

Height, x = 8 yards

Answer:

28.29 inch.

Step-by-step explanation:

So diameter is 9.

Circumference = pi x d

Since KLM and MLN are complementary they add up to 90 degrees.

LM bisects KLN so it divides it to two equal parts so 90/2= 45 degrees

So, KLM and MLN are both 45 degrees.

Answer:

Ima say the answer is 9, likely she bought 6 more new and with the fire half were destroyed of this 6 new posters only are 3 left so she has 12 posters left that means only 3 are added to how much posters she had before, so in some words she started with 9 also 9+3=12.

For where it says write and equation I think the answer would be something like 9+6-3. In where it says work I want to assume is your explaination so you can use the first paragraph I made. Check Its prob a re do of the work you have done to make sure its right. Coming with "Define the value" Im not sure of this but i think is to define your equation.

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.

A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.

The number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.

A fraction is a part of a whole and it can be expressed as a quotient, in which the numerator is divided by the denominator.

We have,

The amount of dog food in the bag = 2/3

The amount of dog food the dog eats per week = 4/9

We need to find the number of weeks that the dog finishes 2/3 of dog food.

The number of weeks:

1 week = 4/9 dog food

Multiply both sides by (9/4 x 2/3)

(9/4 x 2/3) x 1 week = (9/4 x 2/3) x 9/4 dog food

3/2 weeks = 2/3 dog food

[ 3/2 = 1 (1/2) ]

1(1/2) weeks = 2/3 dog food

This means in one and a half weeks the dog finished 2/3 of dog food.

Thus the number of weeks the dog will take to finish 2/3 of a bag of dog food is 1 (1/2) weeks.

Answer:

he save last month $33.25

Step-by-step explanation:

Let us assume last month saving be x

This month saving be 3x + $8

And, the total would be $141

So based on the above information

The equation is

x + 3x + $8 = $141

4x + $8 = $141

4x = $141 = $8

4x = $133

x = $33.25

Hence, he save last month $33.25

Therefore the same is relevant
