The ratio of boys to girls in mrs. Cunninghams class is 2 to 3, there are 18 girls in the class. What is the total number of students in mrs. Cunninghams class

Answer: Final elevation of butterfly = 4m

Final elevation for diver = -11m

Final elevation for whale= 2m

Final elevation for fish = -20m

Step-by-step explanation:

Final elevation= Initial poistion + Change.

A butterfly starts at 20 m and changes -16 m.

Final elevation = 20m +(-16m)

= 20-16 m   [(-)(+)=(-)]

= 4m

A diver starts at 5 m and changes -16 m.

Final elevation = 5m + (-16) m

= 5m- 16 m  [(-)(+)=(-)]

= -11 m

A whale starts at -9 m and changes 11 m.

Final elevation = (-9m)+11m

= 11m- 9m   [-a+b=b-a]

= 2m

A fish starts at -9 meters and changes -11 meters

Final elevation = -9+(-11) m

= (-9-11) m     [(-)(+)=(-)]

=-(9+11)  m   [-a-b=-(a+b)]

=-20m

Hence, Final elevation of butterfly = 4m

Final elevation for diver = -11m

Final elevation for whale= 2m

Final elevation for fish = -20m

Answer:

x=3

Step-by-step explanation:

x = number of toppings on berts pizza

Berts pizza has 1x toppings

Ernies pizza has 4x toppings

there are 15 toppings on both pizzas

x + 4x = 15 (combine like terms)-> 5x=15 (divide both sides by 5)-> x=3

Therefore, the total number of ways the lights can be arranged on the string is: 14! / (2! * 4! * 5! * 2!).

To find the number of ways the lights can be arranged on a string, we need to calculate the total number of permutations.

The total number of lights is 2 red lights + 4 yellow lights + 5 blue lights + 1 green light + 2 pink lights = 14 lights.

Since all the lights are distinct, we can arrange them in 14! (factorial) ways. However, since there are repetitions of certain colors, we need to account for that.

The red lights are identical, so we divide by 2! (the number of permutations of the red lights among themselves).

The yellow lights are identical, so we divide by 4! (the number of permutations of the yellow lights among themselves).

The blue lights are identical, so we divide by 5! (the number of permutations of the blue lights among themselves).

The pink lights are identical, so we divide by 2! (the number of permutations of the pink lights among themselves).

Therefore, the total number of ways the lights can be arranged on the string is:

14! / (2! * 4! * 5! * 2!)

You can calculate this expression to find the specific number of arrangements.

The scientific notation of the wavelength of green light in a spectrum

is 3×10⁻⁶ feet.

In scientific notations numbers are written in the form of a base that is

0  ≤ b < 10 and multiplied by 10ⁿ where n represents integers.

We write large standard numbers in scientific form in a compact manner.

Given, The wavelength of green light in a spectrum is about 0.000003 feet.

Now, the decimal is 6 places before so we have to move the decimal 6 places to the right, and to maintain the actual value we'll raise it to 10⁻⁶.

Therefore, 0.000003 feet,

= 3×10⁻⁶ feet.

So, the wavelength of green light is 3×10⁻⁶ feet.

True. A lambert quadrilateral can be "doubled" to form a saccheri quadrilateral; a saccheri quadrilateral can be "halved" to form a lambert quadrilateral. So, the statement is true.

A Lambert quadrilateral is a type of quadrilateral that has three right angles and one acute angle.

To double a Lambert quadrilateral means to construct a new quadrilateral with twice the area but with the same shape.

This can be done by drawing a line through the acute angle of the original quadrilateral and constructing a new square on each side of the line.

The resulting shape is a Saccheri quadrilateral, which has two right angles and two acute angles.

To halve a Saccheri quadrilateral means to construct a new quadrilateral with half the area but with the same shape.

This can be done by drawing a line through one of the acute angles of the original quadrilateral and constructing a new square on one side of the line. The resulting shape is a Lambert quadrilateral.

The probability that atleast one ball is red is 14/15.

Given that:-

Number of red balls = 4

Number of black balls = 2

One ball is randomly selected, without replacement, the second ball is selected.

We have to find the probability that atleast one ball is red.

There are four ways in which this can happen:-

RR, BR, RB, BB

Where R stands for Red ball and,

B stands for Black ball.

We know that,

Probability that no ball is red + Probability that atleast one ball is red = 1

Hence, we can write,

Probability that atleast one ball is red = 1 - Probability that no ball is red

P(BB) = (2/6)*(1/5) = 1/15

Hence,

Probability that atleast one ball is red = 1 - (1/15) = 14/15

The simple interest earned on $1,272 deposited in a bank for 20 years at 3% annual interest rate is $764.40.

To calculate the simple interest earned on a principal amount deposited in a bank, we use the formula:

Simple Interest = (Principal) x (Rate) x (Time)

where the rate is the annual interest rate, and the time is the number of years the money is deposited.

In this case, the principal is $1,272, the rate is 3%, and the time is 20 years.

Plugging in these values into the formula, we get:

Simple Interest = (1272) x (0.03) x (20)

Simple Interest = $764.40

The probability of having three successes out of nine trials with probability of success being 0.60 is approximately 0.250.

To determine P(x=3) in a binomial situation where n=9 and π=0.60, we can use the formula for the probability mass function of a binomial distribution:

P(x=k) =\((n choose k) * π^k * (1-π)^(^n^-^k^)\)

where "n choose k" is the binomial coefficient, which represents the number of ways to choose k items from a set of n items.

Substituting the given values in the formula, we obtain:

P(x=3) = (9 choose 3) * 0.60^3 * 0.40^6 = (9!/(3!6!)) * 0.216 * 0.04096 ≈ 0.250

Step one:

given

principal= $100

rate= 5%

time = 2 years

Required

The final amount

Step two:

The compound interest formula is

\(A=p(1+r)^t\)

substituting we have

\(A=100(1+0.05)^2\\\\A=100(1.05)^2\\\\A=100*1.1025\\\\A=110.25\\\\\)

The final amount is $110.25

Part A: The stated values is; x = 31π/6

A circle has 360 degrees. We must decrease the present angle to an angle between 0° and 360° in order to determine the reference angle.

As, 360° = 2π radians, subtract 2π = 12π/6 radians for each iteration.

Iteration 1 =>  31π/6 - 12π/6 = 19π/6

Iteration 2 =>  19π/6 - 12π/6 = 7π/6

0 ≤ 7π/6 ≤ 12π/6

Thus, reference angle is found as 7π/6 radians

Part B) The value for the sin x, tan x, and sec x.

sin (7π/6) = -1/2

tan (7π/6) = 1/√3

sec (7π/6) =  1/cos(7π/6) = -1/(√3)/2

sec (7π/6) = -2/√3

Thus, the simplest values of sin x, tan x, and sec x are found.

True, when nesting loops, the inner loop must be completely contained within the outer loop and must use a different control variable.

When nesting loops, one loop is placed inside another loop. The purpose of nesting loops is to execute a set of instructions repeatedly in a structured manner. In this context, the statement is true: the inner loop must be entirely contained within the outer loop, and a different control variable must be used for each loop.

By containing the inner loop within the outer loop, we ensure that the inner loop executes its iterations every time the outer loop iterates. This nested structure allows for more complex and detailed looping patterns.

Using different control variables for the inner and outer loops is necessary to maintain independent control over their iterations. Each loop should have its own variable to track and control its progress. This distinction is crucial in preventing conflicts and ensuring that the loops function as intended.

Therefore, when nesting loops, it is essential to follow these guidelines: the inner loop must be entirely contained within the outer loop, and a distinct control variable should be used for each loop to ensure proper execution and avoid potential errors.

The ratio of the volume of the triangular prism to the volume of the cuboid is 3: 20

Step-by-step explanation:

The volume of the triangular prism V\(_{T}\) = \(\frac{1}{2}\) bh × H, where

The volume of the cuboid V\(_{C}\) = L × W × H, where

∵ The base of the triangular prime is a right triangle with legs 5 cm, 4 cm

∴ b = 5 cm and h = 4 cm

∵ Its height is 9 cm

∴ H = 9 cm

→ Substitute them in the rule of the prism above

∵ V\(_{T}\) = \(\frac{1}{2}\) (5)(4) × 9

∴ V\(_{T}\) = 90 cm³

∵ The dimensions of the base of the cuboid are 6 cm and 5 cm

∴ L = 6 cm and W = 5 cm

∵ Its height is 20 cm

∴ H = 20 cm

→ Substitute them in the rule of the cuboid above

∵ V\(_{C}\) = 6 × 5 × 20

∴ V\(_{C}\) = 600 cm³

→ Find the ratio between them

∵ V\(_{T}\): V\(_{C}\) = 90: 600

→ Divide each term of the ratio by 30 to simplify them

∴ V\(_{T}\): V\(_{C}\) = 3: 20

∴ The ratio of the volume of the triangular prism to the volume of

A unit circle has a radius of 1, so r = 1. The point P(9/10, y) in the IV quadrant will have a positive x-value and a negative y-value.

Using the Pythagorean theorem we know that, x² + y² = r², in a Cartesian coordinate system. We can solve for y by rearranging the formula, r² - x2 = y², or y = ±√(r² - x²).

y = ±√(r² - x²)

y = ±√([1]² - [9/10]²)

Simplify the expression we have

y = ±√(1 - 81/100)

y = ±√(1-0.81)

y = ±√0.19, we choose the negative for quadrant IV.

y = -√0.19

y = -0.4359

Sin -0.4359 = 26 degrees in the IV quadrant, = 360-26 =334 degrees
