If 54 oranges cost 36 naira, then the cost of 3 oranges​ is 2 naira

Unitary method is a method of solving problems by finding the value of one unit and then using that value to find the value of a given number of units

To find the cost of 3 oranges, we can use unitary method which involves finding the cost of one orange and then multiplying it by 3.

Let's first find the cost of one orange

54 oranges cost 36 naira

So, 1 orange will cost:

1/54 of 36 naira = (36/54) naira = (2/3) naira

Now, we can find the cost of 3 oranges by multiplying the cost of one orange by 3

Cost of 3 oranges = 3 x (2/3) naira = 2 naira

As per the unitary method, the list shows the number of each type of animal on this farm is

Number of pigs = x

Number of horses = 2x

Number of cows = 8x

Let us start by assigning variables to each type of animal on the farm. Let's say the number of pigs is "x".

From the problem statement, we know that there are twice as many horses as pigs. Therefore, the number of horses would be 2x.

Further, we know that there are four times as many cows as horses. So, the number of cows would be 4 times the number of horses. Mathematically, we can represent it as:

Number of cows = 4 * Number of horses

Or, Number of cows = 4 * (2x) = 8x

Therefore, we have the number of each type of animal on the farm as follows:

Number of pigs = x

Number of horses = 2x

Number of cows = 8x

This is the same ratio as we found using the unitary method.

Therefore, our solution is correct.

The sum of 3/5 and -6/7 is -9/35

To add fractions with different denominators, we first need to find a common denominator. In this case, the common denominator is the least common multiple (LCM) of 5 and 7, which is 35.

Then, we need to convert both fractions to equivalent fractions with the denominator of 35:

3/5 = 21/35 (multiply both the numerator and denominator by 7)

-6/7 = -30/35 (multiply both the numerator and denominator by 5)

Now that both fractions have the same denominator, we can add them by simply adding the numerators and keeping the denominator

21/35 + (-30/35) = (21 - 30) / 35 = -9/35

Therefore, 3/5 +(− 6/7 ​ ) = -9/35.

Answer: We can use a proportion to estimate the total number of fur seal pups in Rookery A. Let x be the total number of fur seal pups in Rookery A. Then we have:

6269/x = 221/1100

Cross-multiplying, we get:

221x = 6269 * 1100

Dividing both sides by 221, we get:

x = 6269 * 1100 / 221

Simplifying, we get:

x = 31,245.25

Rounding to the nearest whole number, we get:

x ≈ 31,245

Therefore, the estimated total number of fur seal pups in Rookery A is 31,245.

$2,560 needs to be invested at time 3 in order to have $3,200 at time 8.

Since the money grows according to the simple interest accumulation function a(t) = 1.05t, the amount of money A at time t, given an initial amount P, can be calculated using the formula:

A = P + Pr(t)

where r is the interest rate (in this case, 5% or 0.05) and t is the time period (measured in years).

To determine how much money needs to be invested at time 3 to have $3,200 at time 8, we can use the above formula and solve for P:

3200 = P + Pr(8-3)

3200 = P + 5P(0.05)

3200 = P + 0.25P

3200 = 1.25P

P = 3200 / 1.25

P = 2560

Therefore, an initial investment of $2,560 at time 3 would be needed to have $3,200 at time 8, assuming a simple interest accumulation function with an interest rate of 5%.

The answer to this question is  x = 6

The ratio of the weight to the mass and the value of x in the table is B) The ratio is 10/98, x = 110.

The quantity of matter in an object is measured by its mass, which is commonly expressed in kilogrammes or grammes. Since mass is a scalar quantity, the gravitational field has no effect on it. The force of gravity acting on an object is quantified by weight, which is commonly expressed in newtons or pounds. Weight is a vector quantity that is influenced by the strength of the gravitational field. While an object's mass is constant, its weight might vary depending on the gravitational field.

The ratio of weight to mass according to the given table is:

weight / mass = 196 / 20 = 98/10

The ratio is constant thus for x we have:

1078 / x = 98 / 10

Using cross multiplication we have:

x = 1078 (10) / 98 = 110

Hence, the ratio of the weight to the mass and the value of x in the table is B) The ratio is 10/98, x = 110.

We can use the trigonometric identity for the sine of a difference:

sin(a - B) = sin a cos B - cos a sin B

We are given that sina = -3 and sinß = 3, so we need to find the cosine of each angle. Since the terminal side of a lies in quadrant III and the terminal side of 6 lies in quadrant I, we can use the following relationships:

cos a = -sqrt(1 - sin^2 a) = -sqrt(1 - 9) = -sqrt(-8) = sqrt(8)i

cos ß = sqrt(1 - sin^2 ß) = sqrt(1 - 9) = sqrt(-8) = sqrt(8)i

Note that we use i to indicate the imaginary unit, since the result involves a negative square root. Therefore, we have:

sin(a - B) = sin a cos ß - cos a sin ß

= (-3)(sqrt(8)i) - (sqrt(8)i)(3)

= -3sqrt(8)i - 3sqrt(8)i

= -6sqrt(8)i

Hence, the exact value of sin(a - B) is -6sqrt(8)i.

We apply the trigonometric identity for the sine of a difference:

sin(a - B) = sin(a)cos(B) - cos(a)sin(B)

We use Pythagorean identity to find the cosine values:

cos^2(a) = 1 - sin^2(a) = 1 - (-3)^2 = -8

cos(a) = ±√8i

cos(a) = -√8 (Since a lies in quadrant III, the cosine value is negative.)

we also have that:

cos^2(B) = 1 - sin^2(B) = 1 - 3^2 = -8

cos(B) = ±√8i

cos(B) = √8. (Since B lies in quadrant I, the cosine value is positive. )

To determine if each ordered pair is a point of intersection between the line x - y = 6 and the circle y² - 26 = -x², we need to substitute the values of x and y in both equations and see if they are true for both.

For the ordered pair (1, -5):

x - y = 6 becomes 1 - (-5) = 6, which is true.

y² - 26 = -x² becomes (-5)² - 26 = -(1)², which is false.

Therefore, (1, -5) is not a point of intersection.

For the ordered pair (1, 5):

x - y = 6 becomes 1 - 5 = -4, which is false.

y² - 26 = -x² becomes (5)² - 26 = -(1)², which is true.

Therefore, (1, 5) is a point of intersection.

For the ordered pair (5, -1):

x - y = 6 becomes 5 - (-1) = 6, which is true.

y² - 26 = -x² becomes (-1)² - 26 = -(5)², which is false.

Therefore, (5, -1) is not a point of intersection.

The more bidders there are, the more likely it is that the highest bid variable bmax will be updated multiple times as each agent outbids the previous highest bidder.

Let us denote the expected number of times the variable bmax gets updated by E.

We can start by computing the probability that the ith agent updates bmax. This is equal to the probability that agent i has the highest bid among the first i bids. Since all bids are distinct and the order of the agents is chosen uniformly at random, the probability of this event is 1/i.

Therefore, the expected number of updates to bmax is:

E = ∑i=1 to n P(agent i updates bmax)

E = ∑i=1 to n 1/i

This is the harmonic series, which diverges as n approaches infinity. Therefore, as the number of bidding agents increases, the expected number of updates to bmax increases without bound.

In practical terms, this means that the more bidders there are, the more likely it is that the highest bid variable bmax will be updated multiple times as each agent outbids the previous highest bidder.

The standard deviation of the ACT scores is approximately 4.2.

Standard deviation is a measure of the amount of variation or dispersion in a set of data values. It indicates how much the data values deviate, on average, from the mean (or average) of the data set. A higher standard deviation indicates greater variability or spread in the data, while a lower standard deviation indicates less variability or spread.

According to the given information:

To find the standard deviation of ACT scores, we can use the given information about the mean and the percentage of scores above a certain threshold.

Given:

Mean (μ) = 21.4

Percentage of scores above 26 = 15%

Since the distribution is approximately normal, we can use the Z-score formula to find the Z-score corresponding to the given percentage. The Z-score is the number of standard deviations a particular value is from the mean in a normal distribution.

Z-score formula:

Z = (X - μ) / σ

Where:

Z = Z-score

X = Value (in this case, 26)

μ = Mean (21.4)

σ = Standard deviation (to be found)

We can rearrange the formula to solve for σ:

σ = (X - μ) / Z

Substituting the given values:

X = 26

μ = 21.4

Z = Z-score corresponding to 15% (which can be found using a standard normal distribution table or a Z-score calculator)

Assuming a standard normal distribution table or calculator gives us a Z-score of approximately 1.04 for a percentage of 15%, we can plug in the values:

σ = (26 - 21.4) / 1.04

σ = 4.4 / 1.04

σ ≈ 4.2 (rounded to the nearest tenth)

So, the standard deviation of the ACT scores is approximately 4.2.

The Moon and Sun's gravitational pull on the waters of Earth is what causes tides.

The Moon and Sun's gravitational pull on the waters of Earth is what causes tides. The gravitational pull between any two objects is determined by both their masses and their separation from one another. Although having a far larger mass than the Moon, the Sun is located much distant from Earth. This indicates that the Moon's gravitational pull on the oceans of Earth is greater than that of the Sun.

The water on the side of the Earth that faces the Moon is drawn towards it by the Moon's gravitational attraction, creating a high tide. Another high tide results from simultaneous pulls on the opposite side of the Earth's water towards the Moon.

The moon has a greater effect on Earth's tides than the sun because it is much closer to Earth.

Gravitational pull is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun. It also keeps the moon in orbit around Earth.

The Moon and Earth exert a gravitational pull on each other. On Earth, the Moon's gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. These bulges create high tides. The low points are where low tides occur.

The moon has a greater effect on Earth's tides than the sun because it is much closer to Earth. The gravitational force between two objects decreases as the distance between them increases, so the moon's gravitational pull on Earth's oceans is much stronger than the sun's. However, during certain times of the year, when the sun and moon are aligned, their combined gravitational pull can create especially high or low tides, known as spring tides.

The total length of all 10 ribbons is 35 inches when they are placed end to end.

Inches are a unit of length in the imperial system of measurement, which is primarily used in the United States, the United Kingdom, and some other countries. One inch is equal to 1/12 of a foot or 2.54 centimeters.

The inch is commonly used to measure the length or distance of small objects, such as the size of a computer screen, the length of a pencil, or the height of a person. Inches are also used to measure the dimensions of larger objects, such as the width of a door or the size of a piece of furniture.

If John has 10 ribbons, each measuring 3 ½ inches long, we can find the total length of all the ribbons by multiplying the length of one ribbon by the number of ribbons:

Total length = 10 × 3 ½ inches

To multiply a whole number and a mixed number, we can first convert the mixed number to an improper fraction, then multiply:

Total length = 10 × (7/2) inches

Total length = 35 inches
