As per the given number nine billion is 8.9 x 10⁹ greater than one hundred million

Numbers are a fundamental part of our lives and the world around us. Understanding how to compare and perform arithmetic with large numbers is an important skill.

In this question, we are comparing two large numbers: nine billion and one hundred million.

The correct answer is (a) 8.9 x 10⁹.

The number nine billion can be written as

=> 9 x 10⁹,

where 10⁹ means 10 raised to the 9th power, or 10 multiplied by itself 9 times, which is equal to 1,000,000,000.

Meanwhile, one hundred million can be written as 100 x 10⁶, or 100 million.

To compare these two numbers, we subtract 100 million from nine billion, which gives us 8.9 x 10⁹.

The area of the shaded region is equal to sin(2).

The shaded region is a sector of a circle with radius r and central angle 2. To find the area of the shaded region, we first need to find the radius of the circle, which is given by r2 = sin(2). Taking the square root of both sides, we get r = sqrt(sin(2)).

Next, we need to find the area of the sector, which is given by:

A = (r^2 * 2) / 2 = r^2

Substituting r = sqrt(sin(2)), we get:

A = (sqrt(sin(2)))^2 = sin(2)

Therefore, the area of the shaded region is equal to sin(2).

We know Ms. Langlois has 26 pencils.

We DO NOT know the amount of pencils that Mr.Cox has, we can use the variable "x" to represent Mr.Cox's number of pencils.

An expression is just an expression, not an equation, so it DOES NOT require a "="

The expression could be represented as 26+x

Answer:

To solve this problem, we can use a system of equations. Let x be the number of shoes sold at $66.95 and y be the number of shoes sold at $84.95. We know that:

x + y = 240 (because 240 pairs of shoes were sold in total)

66.95x + 84.95y = 17,652 (because this is the total amount of money earned from shoe sales)

To find the number of each type of shoe sold, we can use substitution method, by solving one equation for one variable and substituting that expression into the other equation.

We can solve the first equation for y:

y = 240 - x

Then we can substitute this expression into the second equation and solve for x:

66.95x + 84.95(240 - x) = 17,652

66.95x + 21,068 - 84.95x = 17,652

-18x = -3,416

x = 176

So, 176 pairs of shoes were sold at $66.95. To find the number of shoes sold at $84.95, we can substitute this value of x into the first equation:

y = 240 - 176 = 64

So, 64 pairs of shoes were sold at $84.95.

In conclusion, we can recover the information and the manager can know that 176 pairs of shoes were sold at $66.95 and 64 pairs of shoes were sold at $84.95.

A. The graph of the stock value would start at a low point on the left side of the graph and gradually increase in value as it moves to the right. The line representing the stock value would start to level off and then suddenly drop, representing the quick decrease in value.

B. If the stock gradually decreased during the middle of the day, the line on the graph would start at a high point, gradually decrease in value, and then level off.

The answer indicates that it will take 2.38 yrs to for population to treble in size.

A population is any large group that has at least one resource is common. People do not make up all populations. Population numbers can include, but aren't limited to, people, animals, groups, organizations, buildings, houses, trucks, farms, and things.

Let's call the population after it has tripled "P_triple". Then:

P(t) = 3P(0) = 3 * 95

P_triple = 285

We want to find the time t such that P(t) = 285, so we'll set the two expressions equal to each other:

95 (1.53)^t = 285

Dividing both sides by 95:

(1.53)^t = 3

Taking the natural logarithm of both sides:

t = log(3) / log(1.53)

Approximating using a calculator:

t = approximately 2.38 years

So it will take approximately 2.38 years for the population to triple in size.

The final distance of the port from the ship is 75.63 km and the final bearing of the port from the ship is 263.57° using cosine and sine rules.

Considering the triangle formed by the ship ∆ABC where A, B and C are the points for; the port, where the ship changes its course, and its final bearing. The final distance "a" of the port from the ship is calculated with cosine rule as follows;

a² = b² + c² - 2(b)(c)cosA

a² = 40² + 70² - 2(40)(70)cos82°

a² = 1600 + 4900 - 5600cos82°

a² = 5720.63 {take square root of both sides}

a = 75.63

For the triangle ABC, by sine rule;

a/sinA = b/sinB = c/sinC

75.63/sin82° = 70/sinC

C = sin⁻¹(70 × sin82°/75.63) {by cross multiplication}

C = 66.43

angle C = 60 + 6.43 {60° is an alternate angle with angle 30° at the point B where the ship chenged course and 6.43° is a complementary angle at the 3rd quadrant of point C}

The final bearing of the port from the ship is calculated as;

180° + (90 - 6.43)° = 263.57°

a. The different sequences possible are 1200.

b. The different sequences have all hip, knee, and shoulder surgeries scheduled consecutively are 720.

c. The different schedules begin and end with knee surgery is 6.

(a) To find the number of different sequences, we can use the permutation formula n!/(n-r)!

where n is the total number of surgeries and r is the number of surgeries of each type that we need to schedule.

For knee surgeries, n = 5 (total surgeries) and r = 3 (number of knee surgeries), so the number of different sequences for knee surgeries is 5!/(5-3)! = 5!/(2!) = 54 = 20.

Similarly, the number of different sequences for hip surgeries is 5!/(5-2)! = 5!/(3!) = 54*3 = 60.

Hence, the total number of different sequences is 20 * 60 = 1200.

(b) To find the number of different sequences with all hip, knee, and shoulder surgeries scheduled consecutively, we first need to find the number of sequences for each type of surgery.

For knee surgeries, n = 3 (number of knee surgeries) and r = 3 (number of knee surgeries), so the number of different sequences for knee surgeries is 3!/(3-3)! = 3!/(0!) = 3! = 6.

Similarly, the number of different sequences for hip surgeries is 2!/(2-2)! = 2!/(0!) = 2! = 2.

For shoulder surgeries, the number of different sequences is 5!

Hence, the total number of different sequences with all hip, knee, and shoulder surgeries scheduled consecutively is 6 * 2 * 5! = 720.

(c) In order to find the number of different schedules that begin and end with knee surgery, we first need to find the number of sequences for the middle surgeries.

There are 2 hip surgeries and 2 knee surgeries left to schedule, so the number of different sequences for these surgeries is (2+2-1)!/(2!2!) = 3!/(2!1!) = 3.

Hence, the total number of different schedules that begin and end with a knee surgery is 3 * 2 * 1 = 6.

The probability of winning the game with at least one Ace among the four draws is 0.736.

The probability of winning in this game is calculated as,

There are 4 Aces in a standard deck of 52 cards, so the probability of drawing an Ace on one draw is 4/52.

The probability of not drawing an Ace in 4 draws is (48/52) * (47/51) * (46/50) * (45/49) = 0.264.

The probability of winning is the complement of not winning, which is 1 - 0.264 = 0.736.

Correct option is B, function for the area of the circle in terms of the side of the square is A = [tex]\pi \frac{S^2}{4}[/tex].

Because the area of a square is one of its sides multiplied by itself, the area equals the square of the radius of a circle multiplied by two. Because the radius of the circle is a known quantity, the area of the inscribed square can be calculated numerically.

An “inscribed” square in a square is one in which all of the vertices of the smaller square are on the borders of the bigger square. To do this, the vertices of the smaller square will split each side of the bigger square into two segments, one on each side.

If a square is used to inscribe a circle, the square's side length will match the circle's diameter. As a result, the radius of an inscribed circle is S/2 for a square with length S. hence, the area of a circle is expressed as the square's sides,
