Answer:

When dividing a whole number by a decimal, you can use long division to find the quotient (the answer to the division problem). Here's how to divide 9 by 0.85 using long division:

The quotient is the number above the division line, which is 10 with a remainder of 23/100. Therefore:

9 / 0.85 = 10 with a remainder of 23/100, or 10.5882 (rounded to four decimal places)

So, 9 divided by 0.85 is approximately 10.5882.

The probability of selecting a red pencil and a green M&M is calculated as follows:

p = [number of red pencils / number of pencils] x [number of green M&Ms / number of M&M's].

A probability is calculated as the division of the desired number of outcomes by the total number of outcomes.

The pencil and the M&M are independent events, hence we calculate the probability of each event and then multiply then, as follows:

p = [number of red pencils / number of pencils] x [number of green M&Ms / number of M&M's].

The number of balloons which will not be used by Anissa is 4 balloons.

To make all 5 hats the same, Anissa needs to use the same number of balloons for each hat.

Let us call the number of balloons she uses for each hat "x". Since she's making 5 hats, she'll use a total of 5x balloons. We know that she has 54 balloons in total, so we can set up an equation:

5x = 54

To solve for x, we can divide both sides by 5:

x = 54 / 5

x = 10.8

Since she can't use a fraction of a balloon, she'll need to use 10 balloons for each hat.

= 5 hats x 10 balloons/hat

= 50 balloons used

So Anissa will not use:

= 54 - 50

= 4 balloons.

Based on the calculation, we find that:

(fog)(x) = (15Vx)¹⁵
(gof)(x) = 15V(x¹⁵)
(fog)(x) ≠ (gof)(x)

Function composition can be meant as an operation that takes two functions f and g, and produces a function h = g ∘ f such that h(x) = g. In this operation, the function g is applied to the result of applying the function f to x.

To find (fog)(x), we need to substitute g(x) into f(x). This means that we will replace every x in f(x) with 15Vx. So, (fog)(x) = f(g(x)) = f(15Vx) = (15Vx)¹⁵.

Similarly, to find (gof)(x), we need to substitute f(x) into g(x). This means that we will replace every x in g(x) with x¹⁵. So, (gof)(x) = g(f(x)) = g(x¹⁵) = 15V(x¹⁵).

Now, to determine whether (fog)(x) = (gof)(x), we need to compare the two expressions.

(fog)(x) = (15Vx)¹⁵ and (gof)(x) = 15V(x¹⁵). These two expressions are not equal, so (fog)(x) ≠ (gof)(x).

&

[tex] \tt∠ 2 = 5x + 5 \\ \tt = 5(12) + 5 \\ \tt = 60 + 5 \\ \tt = 65 \degree[/tex]

The required measure of the angles ∠A and ∠C is 25° and 65° respectively.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,
Consider the given triangle ABC,

Since we know that the sum of the interior angle of a triangle is equal to 180°.

∠A + ∠B + ∠C = 180,
2x + 1 + 90 + 5x + 5 = 180

7x + 6 = 90
7x = 84
x = 12

Now,
∠A = 2(12) + 1 = 25°
∠C = 5(12) + 5 = 65°

Thus, the required measure of the ∠A and ∠C is 25° and 65° respectively.

In Mathematics, the translation of a geometric figure to the right simply means adding a digit to the value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure that is translated upward simply means adding a digit to the value on the y-coordinate (y-axis) of the pre-image.

The triangles are similar by SAS rule.

Similar triangles are those triangles which have the same shape, but different size.

The corresponding angles of similar triangles are equal and the corresponding sides are proportional.

Given are two triangles ΔGNH and ΔLNM.

∠N is common to both triangles are thus equal.

So ∠N ≅ ∠N

GN / LN = 40 / (12.5 + 40) = 40/52.5 = (16×2.5) / (21×2.5) = 16/21

HN / MN = 32 / (10 + 32) = 32/42 = (16×2) / (21×2) = 16/21

It is already given that the tanker driver worked for 5 and a half days for 9 hours daily, except on Saturday where they worked for half a day (which means 4.5 hours) and were paid double than the daily rate. It is also known that the month of June has 30 days. So calculating the number of working days, we get approximately 4 working weeks in which 20 days are week days and 4 days are Saturdays.

Total amount earned by the tanker driver = (No. of week days worked × Total hours worked × Rate of pay per hour) + (No. of working Saturdays × Total hours worked × Rate of pay per hour on Saturday)

The given situation can be modeled using a binomial distribution, where the number of trials is 30, and the probability of success is 0.75. We can use the binomial probability formula to find the probabilities for each of the given conditions. The binomial probability formula is:

To begin, let's calculate the amount of snow that evaporated. If 77% of the snow melted, the quantity of snow that is left is 100% - 77%, or 23%, of what was originally there.

This can be represented as:

Snow remaining equals 0.23x.

Assume that x inches of snow were present at the start. Thus, we may construct the equation shown below:

0.23y = 30

By finding y, we obtain:

y = 30 / 0.23 ≈ 130.43

Hence, the initial snowfall measured about 130.43 inches.

We may use the difference between the present depth of snow and the original depth of snow to calculate how much snow fell during the blizzard:

The expression ((-8x⁵)(x⁻³))/(20x²) when simplified, making all exponents positive, will become -2/5.

To simplify the expression ((-8x⁵)(x⁻³))/(20x²), we need to apply the rules of exponents and simplify the coefficients.

First, let's simplify the coefficients:

Next, let's apply the rules of exponents:

Product Rule: When multiplying two exponential expressions with the same base, you can add the exponents. That is, xᵃ · xᵇ = xᵃ⁺ᵇ

Quotient Rule: When dividing two exponential expressions with the same base, you can subtract the exponents. That is, xᵃ / xᵇ = xᵃ⁻ᵇ

This equation represents the same parabola as y=x^(2), but it has been shifted 8 units to the left and 6 units downward.

The translation of a function can be represented by modifying the equation in the form y=f(x-h)+k, where h is the horizontal shift and k is the vertical shift. In this case, h=-8 and k=-6, so the equation becomes:

y=f(x-(-8))+(-6)
y=f(x+8)-6

Substituting the original function f(x)=x^(2) into this equation gives:

The expression (z²)+10z+25)/(z²-3z-40) can be simplified by factoring both the numerator and denominator.

First, factor the numerator:
(z²+10z+25) = (z+5)(z+5)

Next, factor the denominator:
(z²-3z-40) = (z-8)(z+5)

Now, the expression can be simplified by canceling out the common factor of (z+5):
(z+5)(z+5)/(z-8)(z+5) = (z+5)/(z-8)

Therefore, the expression in simplest form is (z+5)/(z-8).

There are restrictions on the variable in this expression. The denominator cannot be equal to zero, so we must exclude any values of z that would make the denominator zero.

The product of the number and its conjugate is 29.

The complex conjugate of a complex number is the number with the same real part and the opposite sign of the imaginary part. In other words, if a complex number is a + bi, then its complex conjugate is a - bi.

For the given number -5 - 2i:

(a) The complex conjugate is -5 + 2i. This is because the real part is the same (-5) and the imaginary part has the opposite sign (2i instead of -2i).

(b) To determine the product of the number and its conjugate, we simply multiply them together:

(-5 - 2i)(-5 + 2i) = 25 - 10i + 10i - 4i^2

Since i^2 = -1, we can simplify this to:

25 - 4(-1) = 25 + 4 = 29

Likelihood that a randomly selected A Train will arrive on time is 0.44 or 44%.

What is the randomly selection?

Random selection is a process of choosing individuals, items, or samples from a population in a way that every member of the population has an equal chance of being selected.

To find the likelihood that a randomly selected A Train will arrive on time, we need to determine the number of A Trains that arrived on time and divide that by the total number of A Trains that arrived at the station.

From the table, we can see that there were a total of 50 trains that were A Trains, out of which 22 arrived on time. Therefore, the probability that a randomly selected A Train will arrive on time is:

P(A Train arrives on time) = Number of A Trains that arrived on time / Total number of A Trains

= 22 / 50

= 0.44

Therefore, likelihood that a randomly selected A Train will arrive on time is 0.44 or 44%.
