a square has an area of 81 yd^2. what is the length of each side

Answers

Answer 1

Answer:

9 yards

Step-by-step explanation:

A square has 4 equal sides, this means the 2 sides we will multiply to get the area are going to be the same. Since it says 81 yards squared and the shape is a square, we can do the square root of 81 which is 9.

Answer 2

Answer: 9x9 or 3x27

Step-by-step explanation:

squares are usually the same length but i would go with 9x9

A word processing program requires a user to enter a 7-digit registration code made up of the digits 1,2,4,5,6,7 and 9. Each number has to be used, and no number can be used more than once. How many codes are possible?

Answers

For the first digit there are 7 choices. For the second digit there are 6 choices (because we can't use the same one again). And so on, until there is only one choice for the last digit.

The number of possible codes is this:
7*6*5*4*3*2*1 = 7! = 5040

Final answer:

To find the number of possible codes, we can use the concept of permutations. There are 7 digits to choose from and we need to select all of them. Therefore, there are 5,040 possible registration codes.

Explanation:

To find the number of possible codes, we can use the concept of permutations.

Since the code must be made up of 7 digits and each digit can only be used once, we can calculate the number of permutations of the 7 digits. The formula to use is nPr = n! / (n - r)!, where n is the total number of elements and r is the number of elements to be selected.

In this case, there are 7 digits to choose from and we need to select all of them.

So we plug in n = 7 and r = 7 into the formula:

nPr = 7! / (7 - 7)! = 7! / 0! = 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5,040

Therefore, there are 5,040 possible registration codes.

Step-by-step explanation:

The 4 arches combine to for a circle, so then you can find the area of the shaded region by subtracting the area of the square from the area of the circle.

The formula for area of a circle is A=[tex]\pi[/tex]r^2

Since the radius of the circle would be 11/2 or 5.5, the area if the circle would be [tex]\pi[/tex] x 5.5^2. This equals 95.0334.

The area of the square would be 11 x 11 = 121.

After the closing of the mill, the town of Sawyerville experienced a decline in its population.
The relationship between the elapsed time, t, in years, since the closing of the mill, and the town's
population, P(t), is modeled by the following function.
P(t) = 12,000 - 2^-t/15
In how many years will Sawyerville's population be 9000?
Round your answer, if necessary, to the nearest hundredth.

Answers

Step-by-step explanation:

P(t) = 12,000 (2)^(-t/15)

9,000 = 12,000 (2)^(-t/15)

0.75 = 2^(-t/15)

ln(0.75) = ln(2^(-t/15))

ln(0.75) = (-t/15) ln(2)

-15 ln(0.75) / ln(2) = t

t = 6.23

Final answer:

The time it would take for Sawyerville's population to decrease to 9000 can be calculated by setting the population function equal to 9000 and solving for 't'. After a series of algebraic transformations, you can isolate 't' and calculate its value with a scientific calculator.

Explanation:

To find the amount of time it will take for Sawyerville's population to fall to 9000 people, we can set up the equation: P(t) = 9000. Therefore, we have 9000 = 12,000 - 2-t/15.

To solve this equation, we first need to isolate the exponential term by subtracting 9000 from both sides, getting 3000 = 2-t/15. Then, we take the natural logarithm (ln) of both sides to remove the exponential term, resulting in ln(3000) = -t/15*ln(2). Divide both sides by -ln(2) and multiply them by 15 to find 't'. The final equation is: t = -15*ln(3000)/ln(2).

In this particular problem, you may need the help of a scientific calculator to compute the value of 't'.

if the mean is 120 and the standard deviation in 24 what is the score that is 3 standard deviations above the mean

Answers

Answer:

192

Step-by-step explanation:

If the mean is 120 and the standard deviation is 24, then 3 standard deviations above the mean would be 24(3) = 72 + 120 = 192.

192 is the score that is 3 standard deviations above the mean.

What is standard Deviation?

The term "standard deviation"  refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

Given:

Mean= 120

Standard Deviation = 24

So, the score for 3 standard deviations above the mean

= 24(3) + 120

= 72 + 120

= 192.

Hence, 192 is the score that is 3 standard deviations above the mean.

Final answer:

To calculate the compound interest, use the formula A = P (1 + r/n)^(nt). For the given values, the final amount after 5 years of monthly compounded interest on $2,000 can be calculated.

Explanation:

To calculate the compound interest, we can use the formula:

A = P (1 + r/n)^(nt)

Where:

A = final amount

P = principal amount ($2,000)

r = annual interest rate (3%)

t = time in years (5 years)

n = number of times the interest is compounded per year (12 for monthly compound interest)

Plugging in the values, we have:

A = 2000 (1 + 0.03/12)^(12*5)

Simplifying the equation will give us the final amount after 5 years of monthly compounded interest on $2,000.

Maria is painting a mural on a brick wall. She is painting 4 circles with radii of 2 inches, 4 inches, 9 inches, and 14 inches. How much paint will she need to fill in all four circles?


She will need ____? square inches of paint for all the circles.

Answers

Answer:

932.58 in ^ 2 is needed

Step-by-step explanation:

What we need to do is calculate the area of all the circles and add it up, so we know how many square inches of paint are going to be needed.

We know that the area of a circle has the following formula:

A = pi * r ^ 2

there are 4 circles:

radio of 2 inches:

A = 3.14 * 2 ^ 2 = 12.56 in ^ 2

radio of 4 inches:

 A = 3.14 * 4 ^ 2 = 50.24 in ^ 2

radio of 9 inches:

A = 3.14 * 9 ^ 2 = 254.34 in ^ 2

radio of 14 inches:

A = 3.14 * 14 ^ 2 = 615.44 in ^ 2

12.56 + 50.24 + 254.34 + 615.44 = 932.58

a total of 932.58 in ^ 2 is needed

Steven rolls a 6-sided nombre cube 3 times.What is the probability of rolling a multiple of 3 on all the rolls?​

Answers

The probability of rolling a multiple of 3 on all three rolls of a 6-sided number cube is [tex]\( \frac{1}{27} \)[/tex].

To find the probability of rolling a multiple of 3 on all three rolls of a 6-sided number cube, we first need to determine the total number of outcomes and the number of favorable outcomes.

Total outcomes for each roll = 6 (since there are 6 sides on the cube).

Favorable outcomes for a multiple of 3 on each roll = {3, 6} (numbers divisible by 3).

Thus, the probability of rolling a multiple of 3 on each roll is 2 out of 6, or [tex]\( \frac{2}{6} \)[/tex].

Since each roll is independent, we multiply the probabilities of each roll:

[tex]\[ P(\text{multiple of 3 on all rolls}) = \left( \frac{2}{6} \right) \times \left( \frac{2}{6} \right) \times \left( \frac{2}{6} \right) \][/tex]

[tex]\[ P(\text{multiple of 3 on all rolls}) = \left( \frac{2}{6} \right)^3 \][/tex]

[tex]\[ P(\text{multiple of 3 on all rolls}) = \left( \frac{1}{3} \right)^3 \][/tex]

[tex]\[ P(\text{multiple of 3 on all rolls}) = \frac{1}{27} \][/tex]

So, the probability of rolling a multiple of 3 on all three rolls is [tex]\( \frac{1}{27} \)[/tex].

Answers

Answer:

The area of the baseboard is 13.5m²

Step-by-step explanation:

Given data

Length of the bed L=15m

Width of of the bed B=9/10m

Area of the board A=?

We know that the area of the board

Area A=length x width

Substituting our given data we have

A=15*9/10

A=135/10

A=13.5m²

Hence the area of the board is 13.5m²

Final answer:

The area of the baseboard that Chris needs to install in his room, represented as a rectangle with length 15 meters and width 9/10 meters, is 13.5 square meters.

Explanation:

In the field of Mathematics, to find the area of a rectangle (which is the shape being represented by the baseboard's dimensions that Chris is working with), you multiply the length by the width. Given that the length of the bed is 15 meters and the width is 9/10 meters, the area of the rectangular baseboard can be found by multiplying these values. So, area = 15 meters * 9/10 meters = 13.5 square meters. Therefore, the area of the baseboard that Chris needs to install is 13.5 square meters.
