the diameter of a football is five times the diameter of a cricket ball ratio of surface area of football and cricket ball is

LenKa [72]

Answer:

25 : 1

Step-by-step explanation:

The diameter of the football is 5 times the diameter of the cricket ball. This means that the radius of the football is also 5 times the radius of the cricket ball.

Let the radius of the football be R.

Let the radius of the cricket ball be r.

This implies that:

R = 5r

Both balls are spherical.

The surface area of the cricket ball is given as:

$a = 4\pi r^2$

The surface area of the football is given as:

$A = 4\pi R^2$

$=>A = 4\pi (5r)^2\\\\A = 100\pi r^2$

Therefore, the ratio of their surface areas is:

A : a

$100\pi r^2 : 4\pi r^2$

= 100 : 4

25 : 1

Alex787 [66]

Hey there,

Your question states: <span>The area on a wall covered by a rectangular poster is 294 square inches. The length of the poster is 1.5 times longer than the width of the poster. What are the dimensions of the poster? </span>

$l= 16 \ x \ 1.25 = 20 in$

Your correct answer would be $\boxed{20}$

Hope this helps.

The olsen agricultural company has determined that the weight of hay bales is normally distributed with a mean equal to 80 pound

Marina86 [1]

Normalcdf(78, 82, 80, 8/√(64)) = 0.9544997361

The standard deviation of the sample mean will be 8/√64 = 1, so you are asking for the probability that the value will be within 2 standard deviations of the mean. This is a number most statistics students are asked to memorize.

Your probability is about 0.9545.

A deck of playing cards has four suits, with thirteen cards in each suit consisting of the numbers 2 through 10, a jack, a queen

Rudik [331]

A. True. There are 52 cards total and you only pick 5. Order doesn't matter.

-------------------------------------------

B. False. Order doesn't matter so you use a combination (instead of a permutation) as choice A shows.

-------------------------------------------

C. False. The answer is roughly 0.000858 as shown by the calculation below

(13/52)*(12/51)*(13/50)*(12/49)*(11/48) = 0.000858

-------------------------------------------

D. False. See calculation below

(13/52)*(12/51)*(11/50)*(10/49)*(9/48) = 0.000495

-------------------------------------------

E. True. See calculation below

(13/52)*(12/51)*(11/50)*(10/49)*(9/48) = 0.000495
this value rounds to roughly 0.0005

The number 8/7 = 1.14285714285714 ... obviously has no exact representation in any decimal floating point system (beta = 10) wit

arlik [135]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

In the first point:

Yes, the Finite Floating Point Structures are considered Where $\beta = 7$

$\to \frac{8}{7}= (1.1)_7$

$\bold{= 1 \times 7^0 + 1 \times 7^{-1}}\\\\$

In the second point:

There is no device with a finite floating-point since the right side is

This equality never happens, then, with the rational numbers ( $\alpha_i$ and $\beta$ is rational).
